Iron Gate Capital

A.J. Schreiner serves as Managing Partner and leads investment decisions, drawing on his own experience as a technology founder and operator. The firm maintains a flat decision-making structure typical of seed-stage funds, with Schreiner working directly with portfolio founders through the due diligence and post-investment phases.

Iron Gate invests primarily at the seed stage, often as the first institutional capital into a company. Initial check sizes generally fall below $3 million. The firm reserves capital for follow-on investments into Series A and B rounds, particularly when portfolio companies demonstrate strong capital efficiency and revenue traction.

Iron Gate leans on Schreiner's network across the Intermountain West, tapping into regional accelerator programs, university spinouts, and founder referrals from existing portfolio CEOs. The firm also participates in syndicates with other early-stage funds, both regional and coastal, that share its thesis on B2B software outside major tech hubs.

Iron Gate does not invest in consumer-facing companies, hardware, life sciences, or capital-intensive cleantech. The firm's operating expertise and thesis are concentrated entirely on enterprise software, applied AI, and adjacent B2B technology sectors where capital efficiency and go-to-market discipline are the primary levers on early returns.

Iron Gate typically leads or co-leads seed rounds, actively setting terms and structuring the financing. The firm will join syndicates as a co-investor when another lead has already established the round, particularly for companies outside its immediate geographic focus but within its B2B enterprise thesis.

The firm concentrates on the Intermountain West and broader North American markets, with a particular emphasis on founders building in Colorado, Utah, and surrounding states. Iron Gate believes these regions hold a concentration of undercapitalized B2B software talent that is systematically overlooked by coastal venture funds.

Iron Gate Capital is a pure-play venture capital firm, not a family office. It raises committed capital from institutional limited partners and family offices, then deploys that capital into seed-stage B2B software companies. There are no affiliated philanthropic vehicles or single-family wealth management operations.
