Altman Capital is the venture capital fund of Jack Altman.
Alt Capital is an early-stage venture capital firm founded in 2024 by Jack Altman, co-founder and chairman of Lattice, the HR software company.[1] Operating as a solo general partner fund, Alt Capital reflects Altman's direct experience as both a founder and operator, leveraging his track record in scaling startups to identify and back ambitious entrepreneurs building transformative companies.[1] The firm's mission centers on partnering with product-driven, mission-oriented founders to provide not just capital but hands-on operational support, particularly in scaling teams and navigating growth challenges.[1]
Alt Capital's investment philosophy emphasizes high-conviction investing in a concentrated portfolio of early-stage technology companies, with particular focus on software, artificial intelligence, and infrastructure sectors.[1] Rather than pursuing a spray-and-pray approach, the firm writes meaningful checks ranging from $1-25 million, investing from inception through Series A, and prioritizes founders building in sectors with the potential for long-term category leadership.[1][6] This selective approach—backing roughly 20 companies from its first fund—reflects a deliberate strategy to be an active partner in each investment rather than a passive capital provider.
Jack Altman's journey to founding Alt Capital is rooted in his success as a founder and operator. As co-founder and chairman of Lattice, a 3 billion dollar HR software company, Altman built deep expertise in scaling technology companies and understanding the challenges founders face.[1] This operational background became the foundation for Alt Capital's launch in early 2024, when Altman raised the firm's inaugural 150 million dollar fund.[1]
The firm's rapid growth trajectory demonstrates strong market validation. In September 2025—less than two years after its founding—Alt Capital closed Fund II at 275 million dollars, remarkably raised in just one week.[1] This dramatic capital raise reflects not only investor confidence in Altman's ability to identify promising startups but also the broader market's appetite for emerging managers with proven founder credentials and operational track records.[1] The quick fundraising stands in contrast to the challenging fundraising environment many emerging venture managers faced in 2025, underscoring Altman's unique positioning.[2]
Alt Capital's defining characteristic is its founder-centric approach. Unlike traditional venture firms staffed primarily by career investors, Altman brings hands-on operating experience from building and scaling Lattice.[1] This translates into tangible value for portfolio companies: Altman provides direct support in team scaling, navigating growth challenges, and leveraging his extensive founder network to connect startups with talent, customers, and future investors.[1]
Rather than diversifying across hundreds of companies, Alt Capital maintains a deliberately concentrated portfolio, allowing the firm to be a meaningful partner to each founder.[1][6] This approach contrasts sharply with mega-funds that deploy capital across dozens or hundreds of companies. By writing checks of $1-25 million and focusing on early-stage rounds where the firm can lead or co-lead financings, Alt Capital positions itself as a true partner rather than a passive investor.[1][6]
The firm demonstrates clear conviction in frontier AI applications and practical vertical SaaS companies, as evidenced by portfolio companies like David AI (developing datasets for speech models) and Owner.com (restaurant industry software).[1] Yet this focus remains flexible enough to back transformative companies across multiple sectors, reflecting Altman's belief in investing in founders rather than categories.[6]
The speed at which Alt Capital raised Fund II—275 million dollars in one week—signals exceptional investor confidence and positions the firm to deploy capital quickly into promising opportunities, a significant advantage in competitive early-stage markets.[1]
Alt Capital emerges at a pivotal moment in venture capital's evolution. The 2024-2025 period marked a significant shift away from the "spray-and-pray" mega-fund model that dominated the pandemic era toward more disciplined, founder-led investing vehicles.[2] Emerging managers with strong operational credentials and founder networks—like Altman—have proven better positioned to navigate this transition than traditional venture firms that accumulated frothy valuations during the zero-interest-rate environment.[2]
The firm's success also reflects a broader trend: the increasing value of founder-operators in venture capital. As the startup ecosystem matures, limited partners increasingly recognize that investors with direct operating experience can provide superior support to portfolio companies, not just capital.[1] Alt Capital capitalizes on this shift by positioning Altman's Lattice experience as a competitive moat.
Additionally, Alt Capital's focus on AI and infrastructure aligns with the most consequential technological trends of the moment. By concentrating on these sectors, the firm positions itself at the intersection of where venture capital's attention and capital flows are converging, increasing the likelihood of backing category-defining companies.[1]
Alt Capital represents a compelling model for the next generation of venture capital: founder-led, operationally engaged, and strategically focused. Jack Altman's ability to raise 275 million dollars in a single week—a remarkable feat in any fundraising environment—suggests that limited partners increasingly value founder credibility and operational track records over traditional venture pedigree.
Looking ahead, Alt Capital's trajectory will likely be shaped by three forces. First, the firm's concentrated portfolio approach will be tested as it deploys Fund II capital; success will depend on whether Altman's founder instincts translate into outsized returns. Second, the AI and infrastructure sectors where Alt Capital is concentrated will continue to attract intense competition from mega-funds, requiring the firm to leverage its founder-operator advantage to win deals and support companies. Third, as emerging managers like Alt Capital prove their model, we may see a broader shift in venture capital toward smaller, more focused funds led by operators rather than career investors.
For the startup ecosystem, Alt Capital's rise signals that founder-led venture capital is no longer a novelty but an increasingly mainstream approach. This shift should ultimately benefit founders, who gain access to investors with direct operating experience and genuine empathy for the challenges of scaling companies. The firm's success will likely inspire other successful founders to launch their own venture vehicles, further reshaping the venture capital landscape toward more founder-friendly, operationally engaged capital.
