Pave Space Closes $40 Million for LYOBA Project

Key Takeaways

1. Pave Space SA, a Swiss deep-tech startup, has closed a $40 million funding round to accelerate development of its orbital kickstage vehicle, LYOBA.
2. The company aims to slash the average 9-month satellite orbit-insertion time down to under 24 hours — a 10x+ improvement for the commercial space industry.
3. Pave Space is set to begin hot-fire testing of LYOBA’s main engine at the former Chavalon thermal plant in Valais, Switzerland, as early as summer 2026.
4. The round arrives as global private space investment hit $12.4 billion in 2025 — a record-breaking 48% year-on-year surge — signaling strong institutional appetite for orbital infrastructure plays.

What Happened?

In a landmark moment for European new-space, Swiss orbital logistics startup Pave Space SA has officially closed a $40 million funding round, marking its most significant capital raise since the company’s founding in November 2023. The announcement was shared via the company’s official social channels and confirmed by industry observers tracking the Swiss deep-tech ecosystem. Headquartered in Renens, Vaud — just minutes from EPFL — Pave Space emerged directly from the Gruyère Space Program (GSP), the student-led initiative that built Europe’s first free-flying, student-made reusable rocket, which flew over 50 times in 2024.

LYOBA Takes Center Stage: What the Capital Will Fund

The $40 million will accelerate development of LYOBA, Pave Space’s flagship kickstage vehicle — a roughly 20-tonne in-space transfer stage designed to bridge the gap between a rocket’s low Earth orbit (LEO) drop-off point and a satellite’s final destination orbit. The vehicle uses storable propellants (rather than cryogenic fuels that boil off quickly), a key engineering choice that eliminates boil-off issues and dramatically simplifies logistics for satellite operators.

Most immediately, a significant portion of the capital will fund the first engine test campaign at the decommissioned Chavalon thermal power plant in Valais, Switzerland — a site described by the team as offering the “isolation, terrain, and infrastructure required for propulsion system testing, just 20 minutes from our offices”. The first test stand is expected to come online in summer 2026, with commercial launch targeting 2029.

Beyond LYOBA, the funding roadmap also supports:

1. In-Orbit Demonstration (2027): Pave’s first satellite inspection mission, entering the Space Situational Awareness (SSA) market to monitor debris and satellites in increasingly congested orbits.
2. GNC Engineering Services (Now): Already revenue-generating today through Guidance, Navigation and Control (GNC) simulation contracts — the company secured two such contracts in 2024.
3. Satellite Life Extension (2030): The company’s ultimate commercial crown jewel — a “Space Handyman” service to refuel, reposition, and maintain aging GEO telecom satellites, delaying costly replacements.

The company’s CEO and co-founder, Julie Böhning, has articulated a step-by-step profit architecture: each phase — from engineering services to kickstage to life extension — is designed as a standalone revenue center, building toward the broader vision of making orbit a permanent industrial environment.

Why This Matters Now: A Perfect Storm for Orbital Infrastructure

Pave Space’s funding close lands at a pivotal inflection point for the global space economy. According to Seraphim Space, private investment in the space sector hit a record $12.4 billion in 2025, up 48% year-on-year — surpassing the previous high set in 2021 and completely recovering from the 2022 downturn. The United States led with $7.3 billion (roughly 60% of the global total), but European players are catching up fast, driven by sovereignty concerns and national security imperatives.

The orbital logistics sub-sector specifically is experiencing surging demand. Impulse Space, the US in-space mobility leader founded by SpaceX engine architect Tom Mueller, raised a $300 million Series C in 2025, bringing its total to over $525 million. French smallsat manufacturer U-Space closed a $28 million Series A backed by the French Ministry of Armed Forces. Toulouse-based Infinite Orbits secured €40 million for GEO inspection and life-extension services. The consistent message from investors across these deals: in-space mobility is the new infrastructure, and early-mover kickstage providers stand to capture significant value as satellite constellations grow denser and more complex.

Switzerland specifically has emerged as a hotbed for this activity. The Swiss Aerial & Space ecosystem counts over 40 VC-backed startups that have collectively raised USD $513 million since 2019, with key talent clusters around ETH Zurich and EPFL. Pave Space’s W.A. de Vigier Foundation prize win in 2025 — earning CHF 120,000 and recognition alongside five other top Swiss startups — underscored its credibility within that ecosystem.

Competitive Landscape: Who Is Pave Space Up Against?

The orbital transfer vehicle (OTV) and kickstage market is becoming intensely competitive, but Pave Space occupies a differentiated European niche. Below is a head-to-head comparison with its two most directly comparable rivals at similar or adjacent stages:

Pave Space leads on propellant practicality and multi-orbit flexibility — its storable-propellant architecture is a genuine engineering differentiator versus cryogenic competitors. However, Quantum Space’s cislunar focus and Infinite Orbits’ operational GEO fleet represent tangible first-mover advantages in their respective niches that Pave will need to navigate carefully as it scales toward its 2027 demonstration.

Bayelsa Watch’s Takeaway

I’ll be direct: this is a genuinely exciting deal, and not just because of the dollar figure. What makes Pave Space’s $40 million round bullish for me is the architecture behind it. Most space startups burn through capital on a single moonshot bet. Pave has built something rarer — a revenue-generating base today (GNC contracts), a near-term catalyst (engine testing in 2026, orbital demo in 2027), and a long-term prize that could reshape the satellite economy (life extension by 2030). That’s not one bet; that’s three stacked bets where each success funds the next.

In my experience covering deep-tech funding rounds, the startups that survive the “valley of death” between seed and Series B are precisely the ones that don’t wait for a single product to work before generating revenue. Pave Space is already in that camp. The Gruyère Space Program heritage — over 50 rocket flights in 2024 alone — gives this team a flight heritage most paper-and-PowerPoint space startups can only dream of.

I generally prefer companies that are building infrastructure over those building applications, and orbital logistics is as infrastructure as it gets. If the global space economy is heading toward $1 trillion+ (as widely projected), someone has to be the shipping lane. I think Pave Space is positioning to be exactly that — Europe’s answer to the orbital delivery problem. For investors watching the Swiss deep-tech scene, this is the round worth paying attention to in 2026.
