Nautilus Strategic Ventures is a Boston-based venture-building firm focused on creating companies and helping a select group of outside founders develop theirs. Founded by people with hands-on operating experience, the firm treats building businesses as its core work and draws on that experience to support early-stage teams. Its assistance includes strategy, go-to-market planning, hiring, and practical execution.

Nautilus is currently building several ventures. CarbonPulse is a consumer mobile app that tracks carbon emissions associated with everyday lifestyle activity and enables users to offset them by purchasing carbon credits in the app. SimConnect is a peer-to-peer marketplace for hourly bookings at privately owned and commercial golf simulator bays. DecreeIQ is an AI-powered legal case intelligence platform for family law and litigation work.

Separately, Nautilus operates The Syndicate, a private investment network whose members consider early-stage companies together. Participation is by introduction, and the network operates as a separate entity from the venture-building work. Through its own ventures, founder support, and investment network, Nautilus brings an operator-led approach to early-stage businesses.
