Moved from a consumer backup product to a purpose-built space-security protocol (OrbitSecure) with real hardware demonstrations across multiple platforms (ISS, Ball Aerospace payload) within a few years -- a genuine technical pivot, not a relabeling.

Small team (reported in the 20s-30s employees) running a specialized product for a narrow customer base of aerospace and defense integrators; capable of shipping and flying real payloads, but scale is inherently limited by the niche.

Accenture Ventures' 2023 strategic investment and the Defense Innovation Unit contract are independently reported, concrete signals of growing traction in the space-security niche.

Applying no-knowledge encryption and decentralized key management to spacecraft, where devices are physically unreachable and connectivity is intermittent, addresses a genuinely different threat model than terrestrial zero-trust products and has few direct competitors.

The ISS demonstration and Ball Aerospace payload deployment are independently reported (PR Newswire, SpaceNews) as achieving flight heritage, which is meaningfully more verifiable than a typical vendor claim, though no adversarial red-team results were found.

Space-based infrastructure security is a small but growing niche as commercial and military reliance on satellites increases; relevant to a narrow but strategically important buyer set (defense, aerospace primes) rather than the broad enterprise market.
