Jack Altman raised a new $275M early-stage fund in a mere week

In an impressive display of venture capital prowess, Jack Altman has successfully launched a new $275 million fund under his firm, Alt Capital, in just a week's time. The co-founder of the HR software startup Lattice, which boasts a valuation of $3 billion, shared this exciting news with The Wall Street Journal. This latest fund marks a significant increase from his initial fund, which raised $150 million in early 2024. With the new capital, Altman plans to invest in approximately 20 early-stage companies. Notable investments from his previous fund included David AI, a startup that specializes in creating datasets for speech models, and Owner.com, a software company for restaurants that has already achieved unicorn status. Jack Altman’s extensive connections and firsthand experience as a founder undoubtedly contribute to his success in the venture capital arena. Although he stepped down as CEO of Lattice in 2024, he remains actively involved as the chairman. His brother, Sam Altman, who gained fame as the president of Y Combinator and continues to be an active angel investor, is not a limited partner in this new fund. Another brother, Max Altman, has also made strides in the investment world, co-founding Saga Ventures, which raised its own $125 million fund in 2024.
