Auriga Cyber Ventures

Managing Partners Michael Kluse and Bryan Rosensteel make all investment decisions. Both founders previously built and exited a cybersecurity company before launching the firm, which means technical diligence and partnership decisions sit with the same two people. No investment committee or external advisors are publicly disclosed.

Auriga typically leads or co-leads pre-seed and seed rounds, taking board seats when leading. In later Series A rounds, the firm has followed on alongside larger institutional investors. This posture reflects the partners' preference for active, concentrated positions where they can meaningfully shape product and go-to-market strategy.

The firm writes first checks at pre-seed, seed, and occasionally Series A stages. Initial check sizes are estimated below $3 million based on disclosed portfolio rounds. Follow-on reserves are held for select companies, though the firm does not publicly disclose its reserve ratio.

Auriga does not invest outside cybersecurity and adjacent enterprise infrastructure, explicitly passing on consumer technology, digital health, fintech, and climate. Within cybersecurity, the firm avoids traditional MSSP models and reseller-heavy businesses, preferring product companies with strong engineering cultures.

Auriga operates as a classic venture capital partnership managed by its two founders. It is not structured as a family office or corporate venture arm, and no institutional parent or anchor LP is publicly disclosed. The lean structure keeps all diligence, sourcing, and portfolio support within the core partnership.

The firm sources primarily through the founders' direct networks within the cybersecurity engineering community. Kluse and Rosensteel maintain active GitHub repositories and contribute to open-source security projects, which generates inbound from technical founders who recognize their work. The firm also co-invests with other operator-led seed funds, receiving referrals from former colleagues and portfolio company CTOs.

Auriga actively co-invests with other early-stage cybersecurity specialists and generalist seed funds. Publicly disclosed co-investors in portfolio rounds include prominent seed funds active in Silicon Valley. The firm's partners emphasize they prefer co-investors who can contribute technical due diligence rather than just capital.
