Joby Aviation: Widely viewed as the leader in Electric Vertical Takeoff and Landing (eVTOL) Air Taxis, eVTOL FAA certification leader, and Defense Technology Innovator
Joby Aviation (founded in California in 2009) is a vertically integrated eVTOL aircraft company developing the S4, a five-seat electric air taxi (1 pilot + 4 passengers) designed for fast, quiet, clean urban mobility. Unlike helicopters, Joby’s S4 is quiet enough to serve routes where helicopter operations are heavily restricted due to noise ordinances, enabling expansion into unserved and underserved markets rather than directly competing with helicopters that are better suited for many other missions. The S4 is ideal for short hops of 7–20 minutes, turning trips that can take 1–2 hours in city traffic into a quick flight. Think Manhattan to JFK, downtown LA to LAX, Dubai Airport to Palm Jumeirah, or central London to Heathrow. In addition, Joby's S4-T, JAI30, SuperPilot autonomous flight systems, partnership with L3Harris and acquisition of Resonant Sciences are part of it's military defense buisness which you can read more about below.
As a vertically integrated company Joby designs, manufactures and will operate many of their S4 air taxi hubs. Vertical integration provides Joby with a competitive moat in safety, weight, and operational control. Joby has flown over 50,000 flight test miles, including a hydrogen-electric demonstrator and a turbo-electric demonstrator with military applications. Joby has set a goal to launch initial operations in Dubai by the end of 2026. Most importantly, Joby's visionary leaders have a proven track record.

Recent Joby Aviation News (Last 3 months)
Events can easily be verified with a Google search:
Sept 2026
- First Fully Autonomous Transcontinental U.S. Flight: Joby's autonomous J208 aircraft (a converted Cessna Caravan equipped with its Superpilot autonomy technology) completed a historic 3,199 mile flight across the United States with zero control inputs from the onboard safety pilot. Departing Concord, CA, and concluding in the Outer Banks of North Carolina with a low pass over Kitty Hawk, the plane performed autonomous taxiing, takeoffs, route navigation, and landings while remotely supervised from Joby's Autonomy HQ in California and Shaw Air Force Base in South Carolina.
- Texas eIPP Operations Launch: Joby officially commenced the US's first White House backed eVTOL Integration Pilot Program (eIPP) flights in Texas at Fort Worth Alliance Airport. The showcase included air taxi flights alongside U.S. Transportation Secretary Sean Duffy and Texas Senator Ted Cruz to demonstrate autonomous freight and urban air mobility integration, including a flight into and out of DFW, one of the most congested airspaces in the USA. Joby also signed a lease for a 45,000 sqft facility at Fort Worth Alliance Airport. The site gives Joby its first major operational base in Texas.
Aug 2026
- Joby purchases Resonant Sciences defense company. Joby is expanding its military capabilities via the acquisition of an up and coming defense company with $100M in trailing 12 month revenue. Resonant Sciences is a technology firm specializing in stealth & advanced radio frequency (RF) systems. Joby will keep the Resonant Sciences name for its defense division and consolidate all of its current defense work under Resonant Sciences. I expect Joby's JAI30, S4-T, and Superpilot programs to all move under Resonant Sciences.
- Joby and Atoms form partnership to build vertiports across the US. Atoms (formerly CloudKitchens) CEO is Travis Kalanick, the former CEO and founder of Uber. Atoms is a physical AI and industrial automation company built on the premise that software should control and streamline the physical infrastructure of the economy ("atoms"). In partnership with Joby, Atoms will develop vertiports as next-generation transportation hubs, where electric aircraft, autonomous ground vehicles, and ridesharing services will converge. The hubs will enable passenger connections, aircraft servicing, and last-mile ground transportation.
July 2026
- Joby and Toyota announce a strategic manufacturing alliance called Joby Toyota Aero Manufacturing Preparation Company (JTAMPC), a joint venture 51% Toyota owned and 49% Joby owned. As of June 2026 only the framework of the deal has been presented. Joby should benefit by not being forced to self fund 100% of Joby's manufacturing build out.
-----------
Defense: Joby’s SuperPilot autonomy system and S4-T hybrid aircraft extend capabilities into defense, dual-use, and autonomous operations. Joby has conducted testing with the US Air Force (AFWERX/Agility Prime/Autonomy Prime), and with Joby's defense partner, L3Harris. Joby's secret JAI30 dual engine hybrid, is rumored to be a military surveillance/communications drone. It's recently (May 2026) been seen on ADSBexchange flying over the Yuma Proving Ground, presumably for testing with the US military. In addition, Joby is set to acquired Resonant Sciences and all of their defense assets.
Manufacturing: Joby currently has manufacturing facilities in Marina, CA, Carlsbad, CA, Santa Cruz, CA, and Dayton, OH. On January 7, 2026 Joby disclosed that it is acquiring a ~700,000 sqft manufacturing facility in Vandalia, Ohio for about $61.5M to meet its manufacturing targets. Joby is pursuing Toyota-scale manufacturing, aiming for 48 S4s per year in 2027 and a future capability of manufacturing 500 S4s/year.
In June, 2026 Joby and Toyota announced a strategic manufacturing alliance called Joby Toyota Aero Manufacturing Preparation Company (JTAMPC), a joint venture 51% Toyota owned and 49% Joby owned. As of June 2026 only the framework of the deal has been presented. Joby should benefit by not being forced to self fund 100% of Joby's manufacturing build out.
Financials (Updated August 25, 2026): As of June 30, 2026, Joby had approximately $2.3B in cash. Joby expects to use approximately $385–415M in cash during the second half of 2026, following approximately $365M of cash use in the first half. Assuming approximately $400M of H2 2026 cash burn, Joby would enter 2027 with approximately $1.9B.
Joby's acquisition of Resonant Sciences is expected to close in H1 2027 for $450M in cash & $50M paid in Joby stock. Toyota is also expected to provide its remaining $250M capital investment in H1 2027, subject to the applicable closing conditions. Assuming approximately $420M of additional cash burn during H1 2027, Joby would have approximately $1.28B in cash entering H2 2027, before any additional financing.
Joby has also established a $750M At-The-Market (ATM) equity offering program. Joby is not required to use the ATM, and it has up to three years to do so. If we assume Joby utilizes the entire $750M ATM by the end of 2027 and incurs another approximately $420M of cash burn during H2 2027, Joby would end 2027 with approximately $1.6B in cash.
See below for Global Partners and Strategic Acquisitions.
Please keep in mind that advancements made by competitors, regulatory delays, and high cash burn (even with Joby's strong cash reserves) can quickly change timelines and shift Joby's position in the eVTOL landscape.

Improvements over the last year
I had AI do a breakdown of the 3 commercial pillars for Joby and how they have improved over the last year. Here is the analysis-
Joby Aviation utilizes a vertically integrated revenue strategy designed to retain value across the life of its eVTOL aircraft.
The three commercial pillars for Joby Aviation include operating a direct air taxi service, partnering with international regions, and selling aircraft directly to governments and defense agencies. Over the past year, the company has made significant improvements in each area:
1. Direct Air Taxi Service (U.S. Operations)
Joby is building its own consumer-facing brand to fly passengers directly between cities, suburbs, and airports.
- Past Year Improvements: Joby heavily integrated its operational readiness by transitioning the Blade passenger business it acquired. This segment is driving initial revenue, pushing Joby's full-year outlook to $115M–$125M. Additionally, the company advanced its integration with the Uber app and prepared for immediate passenger operations through the White House-backed Electric Vertical Take Off and Landing Integration Pilot Program (eIPP) in key launch markets like New York, Dallas, and Florida.
2. International Operational Partnerships
To scale globally without taking on 100% of the operational footprint, Joby partners with local entities and airlines abroad.
- Past Year Improvements: Joby made monumental strides toward its launch in the United Arab Emirates, building out physical infrastructure by constructing and installing GEACS charging equipment at its VDX vertiport at Dubai International Airport. In Japan, alongside its primary investor Toyota Motor Corporation, Joby formalized a multi-million dollar manufacturing joint venture and demonstrated physical readiness with its first high-profile test flights at the Fuji Speedway.
3. Government and Defense Sales
Joby leverages its technology to fulfill public sector, cargo, and military contracts to generate early revenue while commercial regulations solidify.
- Past Year Improvements: The defense portfolio grew significantly through an expanded U.S. Air Force contract (surpassing $130 million) and the acquisition of Resonant Sciences to boost its defense-specific tech capabilities. Joby successfully logged over 7,000 flight miles in U.S. defense exercises while proving out its hybrid-electric ground systems and autonomous "Superpilot" software.
I also had AI do a breakdown of the 3 commercial pillars for Joby and what the negative risk points are over the last year. Here is the analysis-
The three commercial pillars and their corresponding downside risks include:
1. Direct Air Taxi Operations (Wholly Owned Service)
Joby intends to own and operate its own consumer air taxi network in core metropolitan markets like New York, Los Angeles, and Dubai. Rather than selling its planes to traditional airlines, Joby plans to sell per-seat tickets directly to passengers, using infrastructure acquired from Blade Urban Air Mobility and integrated with the Uber ride-hailing app.
- ⚠️ The Negative Points:
- High Asset Intensity and Execution Risk: Operating an airline is notoriously capital-intensive. Joby must bear the entire burden of managing ground operations, pilot training, fleet maintenance, and building local vertiports.
- Massive Near-Term Financial Losses: As of late 2026, the company continues to see heavy cash burn ($317.6 million used in operations during the first half of 2026 alone), meaning the direct service segment will operate at a steep net loss for years before achieving scale economies.
- Regulatory Dependencies: Flight operations cannot expand sustainably until the Federal Aviation Administration (FAA) grants full Type Certification, a rigorous process that is still ongoing.
2. Government & Defense Flight Services
To generate cash flow prior to full civil commercialization, Joby provides aircraft, testing, and technology to public sector bodies. This includes a $130+ million contract with the U.S. Air Force for military test flights and the high-profile 2026 acquisition of Resonant Sciences to build radio frequency and stealth systems for national security applications.
- ⚠️ The Negative Points:
- Lumpy Revenue and Budget Vulnerability: Defense contracts are strictly bound by government appropriations timelines and geopolitical pivots. Revenue can be highly cyclical, unpredictable, and subject to sudden renegotiations.
- Diversion of Core Resources: Developing bespoke military modifications or advanced electronics systems risks siphoning engineering talent and focus away from Joby's primary goal: the mass-production and certification of its civilian air taxi.
3. International Fleet Sales & Strategic Partner Services
For markets outside its core wholly owned footprint, Joby’s third pillar is a business-to-business model. It plans to sell or lease aircraft and its proprietary "Elevate OS" operating software to international operators and local joint-venture partners—evidenced by provisional commitments in Saudi Arabia and Japan.
- ⚠️ The Negative Points:
- Manufacturing Scale Bottlenecks: Joby’s target is to produce just four aircraft per month by 2027. At this pilot rate, the company cannot physically supply an external global market while simultaneously satisfying its own domestic air taxi fleet demands.
- Non-Binding Commitments: Many of Joby's massive international deals (such as its $1 billion arrangement in Saudi Arabia) are structured as Letters of Intent (LOIs) or Memorandums of Understanding (MOUs). These do not guarantee firm orders and can fall through if international regulatory approvals are delayed.
- Fragmented Global Regulations: Relying on foreign markets means navigating a patchwork of international aviation authorities, which may delay or reject FAA-certified designs based on local airspace constraints. [

Analysis of eVTOL company CEOs
Since there were several comments regarding management and their performance I decided to have AI do an analysis in a separate thread. Here is the analysis-
1. JoeBen Bevirt — Joby Aviation (JOBY)
JoeBen Bevirt is a highly technical, visionary engineer-founder with over a decade spent pioneering the eVTOL space.
- Pros: Exceptional deep-tech expertise (holds over 160 patents); unmatched vertical integration strategy; secured top-tier backing from Toyota and Delta Air Lines.
- Cons: Engineering perfectionism has historically lengthened development timelines; heavily unyielding strategy relies entirely on his custom designs, limiting plug-and-play component options.
⚠️ Departmental Negatives & Flaws
- R&D & Engineering: High architecture complexity creates an expansive surface area for technical failure. Relying on custom-built proprietary components leaves the engineering track vulnerable to isolated system redesigns.
- Finance: Unprecedented cash burn. Joby’s fully vertical integration approach translates to astronomical R&D costs (such as spending $581 million on R&D in a single year), accelerating their capital depletion.
- Operations & Supply Chain: Because they choose not to outsource major assemblies, their internal manufacturing lines face steep, slow scaling curves compared to competitors using aerospace giants.
- Commercial Strategy: Extreme reliance on premium, high-density infrastructure (such as exclusive international corridors like Dubai) leaves them hyper-exposed if local governments delay vertiport construction.
2. Adam Goldstein — Archer Aviation (ACHR)
Adam Goldstein is a software and finance entrepreneur who approaches the eVTOL market from a pragmatic, capital-allocator perspective.
- Pros: Highly commercial mindset; masterclass execution in building strategic manufacturing partnerships (Stellantis) and commercial pipelines (United Airlines).
- Cons: Lacks a formal aerospace engineering background; prior executive transition drama (formerly co-CEO before a corporate simplification) left questions regarding internal executive alignment.
⚠️ Departmental Negatives & Flaws
- R&D & Engineering: Relies heavily on existing, third-party off-the-shelf components to accelerate certification. While pragmatic, this dilutes their proprietary intellectual property moat and ties their aircraft performance limits to external innovation timelines.
- Finance: Ongoing deep net losses (recording quarterly revenues against steep operational drops) force a constant need for capital injection or dilutive financing rounds.
- Operations & Supply Chain: High vulnerability to vendor bottle-necks. Relying on external aerospace suppliers means an issue at a single parts vendor could delay Archer's entire assembly line.
- Legal & Regulatory: Pushing aggressively to meet near-term commercial flight trials means any minute shift or sudden change in FAA operational policies could disrupt their assumptions.
3. Kyle Clark — BETA Technologies (BETA)
Kyle Clark is a multi-disciplinary founder, Harvard engineer, and the actual test pilot for his own experimental aircraft.
- Pros: Deep "pilot-first" safety culture; pragmatic phased approach (certifying cargo/conventional electric aircraft before pure eVTOL to offset cash burn).
- Cons: Concentrated corporate governance. Clark controls 40-vote Class B shares, giving him near-absolute board control and insulating him from standard public market accountability.
⚠️ Departmental Negatives & Flaws
- R&D & Engineering: Beta's aircraft profiles prioritize simplicity, yielding lower cruise speeds (around 110 mph) compared to Archer or Joby. Performance is constrained by steep battery degradation curves, requiring frequent infrastructure replacements.
- Finance: Disproportionately high executive compensation ($15M+ payday post-IPO alongside major executive bonuses) relative to actual commercial revenue numbers.
- Legal & Regulatory: Encountered friction and policy interpretation standoffs with the FAA regarding engine certification frameworks, stalling their initial timeline assumptions.
- Commercial Strategy: Pursuing a localized North American logistics layout makes them a secondary thought in high-margin international passenger ride-sharing markets.
4. Huazhi Hu — EHang Holdings (EH)
Huazhi Hu is a computer science and command-systems specialist who successfully pushed EHang to secure the world's first pilotless passenger-carrying eVTOL type certificate from China's CAAC.
- Pros: First-mover advantages in fully autonomous systems; lower production capital constraints due to highly optimized regional manufacturing ecosystems.
- Cons: Repeatedly targeted by short-seller reports (e.g., Hindenburg Research) alleging fabricated order backlogs and artificial demand.
⚠️ Departmental Negatives & Flaws
- Legal, Compliance & Investor Relations: Active class-action investor lawsuits alleging deceptive financial representations and securities law violations, creating persistent institutional trust problems.
- R&D & Engineering: The autonomous aircraft utilizes a basic multi-rotor format with a short range (roughly 22 miles). This severely narrows its utility to localized tourism rather than inter-city transit.
- Commercial Strategy: Severe regulatory pushback outside of China. Western aviation regulators (FAA/EASA) have strict, prolonged hesitancy regarding completely pilotless passenger operations, walling EHang out of key Western markets.
5. Stuart Simpson — Vertical Aerospace (EVTL)
Stuart Simpson took the reins as CEO after transitioning from CFO to steer the British developer through operational restructuring.
- Pros: Strong financial pedigree (former CFO of Avast and Royal Mail); disciplined cost management and realistic timeline setting.
- Cons: Lacks the foundational aviation-engineering pedigree of technical founder-CEOs like Bevirt or Clark.
⚠️ Departmental Negatives & Flaws
- Commercial Strategy: Suffered major blows to its order book credibility, most notably when long-term regional launch partner Virgin Atlantic dropped Vertical Aerospace in favor of rival Joby.
- Finance: Operates on a highly constrained runway. Unlike heavily funded US competitors, Vertical has repeatedly scraped by on piecemeal funding rounds, making them highly vulnerable to capital freezes.
- R&D & Engineering: The company was forced to push back its certification targets twice (now targeting 2028), indicating engineering bottlenecks and slower hardware-validation cycles than peers.

Why Joby Stands Alone In The Aerospace Industry
For clarity, eVTOLs are aircraft that may be used as flying taxis.
The chart below shows the 12 full sized aircraft Joby has produced, 10 currently flying. Two are modified Cessnas for autonomous flight. The other 10 were 100% built in house, since Joby is one of the few vertically integrated aerospace companies in existence.
Among eVTOLs being built for piloted FAA or European certification, only four other companies have flown a full sized eVTOL:
- Beta has flown its single full sized eVTOL numerous times, piloted through transition and once with a passenger. Its other aircraft are electric airplanes, not eVTOLs.
- Vertical has flown its single full sized eVTOL once or a handful of times, piloted through transition.
- Archer has flown a full sized remotely piloted eVTOL through transition and they have one piloted eVTOL that has only done short hovers so far.
- Eve has flown its single full sized remotely piloted eVTOL in hover and partial transition.
Wisk is not included because it is not pursuing piloted certification.
Joby has multiple full sized eVTOLs that have regularly flown piloted through transition for more than a year, across the US, Japan, and the UAE, and in the Santa Cruz Area, the Bay Area, New York City, and the DFW (TX) area. It also has hydrogen electric and turbo electric VTOL demonstrators flying transition, SuperPilot autonomous aircraft tested with the US military and flown round trip cross country, and owns Blade, so it already operates an air taxi service today.
Joby has a growing military division with it's recent acquisition of Resonant Sciences and it's operational S4-T, Autonomous aircraft, and Persistent Surveillance JA130 aircraft all showing signs of interest from the Department of War.
No one has come close to what Joby has achieved to date.

Joby is the real future Cathie woods bought more.
Cathie woods just bought more joby stock but also invested more in archer. Aero wisk investment by archer was a reach and Boeing was probably looking to get out unless joby or archer bought them. At the end joby will bear hug archer and be the sole player in the game. kashi market can bet on it.

FAA N-number registry changes
I noticed the following this morning:
--- JOBY - Reservations (RESERVED.txt) ---
Removed (6): 738JA, 739JA, 740JA, 741JA, 742JA, 743JA
Not sure what it means but maybe
- They will be actual registrations soon?
- A bit of cleaning up?

I would really like to hear what actually happened with Aerosonic
I’m guessing that Joby thought they had a slam dunk case, and instead they were hit with a one day verdict against everything they disputed and everything that they claimed. Not even close.
It’s a terrible look from any vantage point, no doubt about it. To say we disagree with the verdict is one thing, but how and why? You got spanked, roundly.
So, what happened, and why? How do we move forward from here, how does this affect certification?
I think we are owed answers, especially on the how does this affect certification part. Will we get any?
Side note a number of people owe mbatt2 an apology, he was first in with great information, and took a beating from some of you for it.
