Fortastra Raises $30M Series A Led by First In for On-Orbit Security Spacecraft

Fortastra Closes $30M Series A

Fortastra, a spacecraft manufacturer focused on on-orbit security, has raised $30 million in Series A funding. The round was led by First In and included participation from Rsquared, ATX Venture Partners, Upfront Ventures, Side Door Ventures LLC and Space Capital. The funding date is recorded as October 8, 2026.

What Fortastra Does

Fortastra builds low-cost, maneuverable spacecraft for on-orbit security, protecting government and commercial satellite infrastructure. The company is headquartered in Torrance, California.

Its approach combines:

• Commercial components to keep costs low
• High-rate manufacturing to produce spacecraft at scale
• Onboard autonomy so its spacecraft can operate with limited ground intervention

According to the company description, these spacecraft are designed to hold position near critical assets, assess surrounding activity and respond before an anomaly becomes a threat.

Company Background

Fortastra was founded by CEO Mike Smayda. The company moved from its December 2025 seed round to its first on-orbit mission, Watchdog V0, in about a year — a notably short timeline that speaks to its manufacturing and deployment model.

Deal Context

The Series A brings $30 million in equity capital to a company operating in the emerging on-orbit security segment. The investor list spans several venture firms with space and deep-tech exposure, including Space Capital and Upfront Ventures, alongside the lead, First In.

No valuation, use-of-proceeds details or additional terms were included in the funding data.

Why It Matters for Acquisition Watchers

On-orbit security is a niche but strategically important category as government and commercial operators seek to protect satellite infrastructure. Fortastra's positioning — low-cost, maneuverable spacecraft with onboard autonomy — targets a capability gap that defense and space customers are actively evaluating.

The company's rapid progression from seed to first on-orbit mission suggests execution velocity that could be attractive to larger aerospace and defense primes or to space-infrastructure consolidators. Its investor base, which includes space-focused funds, may also signal continued syndicate support for follow-on rounds.
