Durham-based pre-seed investment partnership co-founded April 2026 by Austin Carroll (CEO of Warrant) and Austin Armstrong (CEO of Syllaby; Co-Founder of AI Marketing World Conference). HQ at 601A Foster Street in Downtown Durham, physically co-located with Warrant. Writes $5,000 angel checks and leads deal-by-deal SPVs up to $100,000; states a target of 10-12 investments per year. Invests post-product, often first check in. Stated thesis: founders with an unfair insight or distribution advantage, in sectors where the Triangle has a structural edge. Core sector focus: financial services and fintech, martech and GTM infrastructure, healthcare and diagnostics. Conviction-building: education and edtech, defense and government tech, sports tech, hardware and deep tech, energy and battery tech. In-person founder community with office space, founder dinners, GTM workshops, pitch practice, investor office hours, and operator-led tactical sessions. Stated exclusions: no pre-product, no stealth software (hardware exception), no fully-remote founding teams, no pharma/biotech with 7-10 year commercialization runways, no services firms, no brick-and-mortar retail. Disclosure: Austin Carroll and Austin Armstrong are married; Warrant (also in this directory) is a portfolio-eligible company under this fund's thesis.
