The most important part of a satellite is often the part you cannot see once it’s launched. It’s the quiet negotiation between metal, vacuum, and radio waves, a conversation happening across a surface that must be both impossibly large in function and impossibly small in transit. At Space Air Technologies, that surface is a sheet. A sheet that folds, like origami, into a flat package for its rocket ride, and then unfurls in the silence of orbit to listen across five different bands of the spectrum at once [Space Air Technologies, June 2026].
Founded in Helsinki in 2026, Space Air is a hardware play in a software-saturated new space economy. Its bet is architectural: replace the constellation of rigid, band-specific antenna dishes on a satellite with a single, lightweight, multi-band membrane. The company claims this can mean a 90% reduction in mass compared to traditional reflectors, near-zero standby power, and a dramatic cut in deployment complexity [Space Air Technologies, June 2026]. For an industry where every gram costs thousands of dollars to lift, and where capability is often a trade-off against volume, the promise is a fundamental change in the satellite’s form factor.
The architectural wedge
Satellite design is an exercise in brutal constraints. Adding a new capability,say, an X-band radar for earth observation alongside a Ku-band transponder for communications,typically means bolting on another dedicated antenna system. Each one adds weight, power draw, and mechanical complexity. Space Air’s patented thin-membrane antenna aims to collapse that stack. By combining L, S, X, Ku, and Ka band functionality into one aperture, a single spacecraft could theoretically perform missions that would otherwise require multiple satellites or a prohibitively cluttered bus [Space Air Technologies, June 2026].
The technology’s current state is captured in a specific, hard-won acronym: TRL 6, or Technology Readiness Level 6. In aerospace parlance, this means the core technology has been demonstrated in a relevant environment,not just a lab bench, but in conditions that simulate the stresses of space [NASA NTRS, retrieved 2026]. It’s a critical gate, signaling to investors and potential customers that the physics work and the thing can be built. The company holds two European patent families protecting the antenna architecture and its passive deployment mechanism [Space Air Technologies, June 2026].
A founder pair built for the long game
The team behind this high-stakes hardware bet is a study in complementary depth. CEO Mikko Punnala is a retired Finnish Air Force Colonel with over three decades in defense and aerospace, who recently completed a doctorate examining the internationalization of small and medium-sized enterprises in the new space economy [Space Air Technologies, June 2026] [ESA BIC Finland, retrieved 2026]. He has co-authored research on the architecture of digital platforms in space and spoken at industry summits, positioning himself as both an operator and a strategist [ResearchGate, retrieved 2026] [Nordic Space and Defense Summit 2026, March 2026].
His co-founder, CTO Mayank, is the inventor of the core antenna technology. The company’s materials identify him by a single name, noting his doctorate in small-satellite systems and his expertise in radio-frequency and multi-band communications [Space Air Technologies, June 2026]. This pairing,the seasoned defense strategist and the PhD inventor,is a classic deeptech template, designed to navigate the twin mazes of technological risk and customer adoption in the institutional markets of satellite operators and defense agencies.

Funding and the path to orbit
Space Air is currently raising a round to fund the next, most expensive phase: flight qualification and an in-orbit demonstration [Space Air Technologies, June 2026]. While the total size of the round is not publicly disclosed, the company has secured backing from a notable set of early investors including a16z Speedrun, Golden Ventures, and Northside Ventures [PlanetGraph, August 2026]. The involvement of a16z’s early-stage program suggests investor belief in the team’s ability to execute on a deeptech roadmap where milestones are measured in years, not monthly active users.
The company is targeting three primary application areas: satellite communications, airborne platforms, and defense systems [Space Air Technologies, June 2026]. It reports being in active pilot and engagement discussions across these sectors, though it has not publicly named any customers or partners. The ultimate proof point will be a satellite in orbit, its membrane antenna successfully deployed and communicating. Every startup in this category faces the same valley of death between a promising prototype and a revenue-generating product flying on a mission someone paid for.
The risks on the trajectory
The ambition is clear, but the path is lined with the specific perils of capital-intensive hardware. The company’s public traction is currently measured in patents and a TRL rating, not in contracted revenue or named launch customers. Moving from TRL 6 to a qualified, flight-ready product that can survive the vibration of launch and the harsh environment of space is a monumental engineering and financial challenge.
- The funding gap. The cost of building, testing, and launching a demonstration satellite is orders of magnitude higher than the typical SaaS startup’s burn. The undisclosed $2.4 million in total funding reported to date is likely just the beginning [PlanetGraph, August 2026]. Closing a substantial Series A will be a critical, non-negotiable milestone.
- The customer adoption curve. Defense and satellite operators are notoriously conservative buyers with long procurement cycles. Winning a design-in on a major program could take years, requiring relentless business development and patience.
- The execution cliff. A failure in orbit,a membrane that doesn’t deploy, or a signal that degrades,would be a very public and potentially fatal setback. There is no soft launch in space.
The company’s answer to these risks is its technical head start, the patents that protect it, and the credibility of its founding team. A win at the EU’s CASSINI Challenges in 6 also adds a layer of institutional validation [Mikko Punnala X, June 2026].
What to watch in the next eighteen months
For Space Air Technologies, the immediate future is defined by a single, binary event: the in-orbit demonstration. The success of its current fundraise will dictate the timeline for that mission. A successful deployment and validation of the antenna’s performance would transform the company from an intriguing prototype into a serious contender for the next generation of satellite buses.
The cultural question Space Air is implicitly answering is one of material philosophy. In an age where software promises infinite flexibility, they are making a bet on physical intelligence,on the idea that a smarter piece of hardware, a more elegant arrangement of atoms, can still rewrite the rules of a system. It’s a reminder that sometimes, the next platform isn’t built in code, but etched onto a sheet of metal and polymer, folded carefully, and sent into the dark to listen.
