Where we focus

Early-stage B2B SaaS, with the deepest edge in security and AI

Most startups win their first logos on the founder's hustle, then stall when nobody owns onboarding, adoption, and renewals. We back founders at that moment.

B2B SaaS

Pre-seed through Series A companies with early customers and a post-sales function to build in the next 12 to 24 months.

Cybersecurity

Products sold to security and technical buyers, where trust, onboarding, and proof of value decide renewals.

AI-native products

AI products where adoption is the real risk, and disciplined Customer Success turns pilots into lasting contracts.
