Alt Capital is an early-stage venture capital firm founded in 2024 by Jack Altman, co-founder and chairman of HR software company Lattice. The firm operates as a solo general partner fund, reflecting Jack Altman’s direct experience as both a founder and operator. Alt Capital focuses on backing ambitious entrepreneurs building transformative companies, drawing on Altman’s network and track record in scaling startups.
The firm invests in early-stage technology companies across multiple sectors, with an emphasis on software, artificial intelligence, and infrastructure.
Alt Capital’s strategy leverages Jack Altman’s founder background to identify and support teams with strong product vision and long-term potential.
In September 2025, Jack Altman announced the close of Alt Capital Fund II at 275 million dollars, raised in just one week. This follows the firm’s inaugural 150 million dollar fund raised in early 2024.
Fund II represents a significant step up in scale, designed to increase both the number of portfolio companies and the size of individual commitments. The fund will continue to target early-stage rounds, writing meaningful checks to lead or co-lead financings.
The quick fundraising reflects strong investor demand and confidence in Altman’s ability to identify promising startups, supported by his reputation as the founder of a 3 billion dollar company.
Leadership
Alt Capital is led by Jack Altman, who runs the firm independently as a solo general partner. Altman brings direct founder experience from building Lattice, where he served as CEO until 2024 and continues as chairman. He is part of the broader Altman entrepreneurial family, with his brothers Sam Altman and Max Altman also active in venture capital, though neither are investors in this fund.
Investment Strategy
Alt Capital takes a high-conviction approach, concentrating on a relatively small number of companies where it can be an active partner.
The firm prioritizes founders who are product-driven, mission-oriented, and building in sectors with the potential for long-term category leadership. Altman leverages his operating background to provide hands-on support, particularly in scaling teams and navigating growth challenges.
Notable Investments
From its first fund, Alt Capital invested in about 20 early-stage companies. These include David AI, a Y Combinator–backed startup developing datasets for speech models, and Owner.com, a unicorn building software for the restaurant industry.
The fund’s portfolio reflects a mix of frontier AI applications and practical vertical SaaS companies.
Notable Exits
As a relatively new firm, Alt Capital has not yet reported notable exits.
Other
Alt Capital is notable for its speed of fundraising, with Fund II closed in a single week, and for operating under a solo general partner model, unusual at this scale.
The firm benefits from Jack Altman’s strong founder credibility and deep ties in Silicon Valley.
