About Alpha Partners
Steve Brotman is listed as founder and managing partner, and he is the person the firm names when it describes its origins. The firm's own materials date its start to 2013, while some third-party profiles give 2012 or 2014. Brian Smiga appears as a co-founding partner and Gal Gitter as a partner. Reporting on the third fund says the first fund was about $10 million. Fund III reached a final close in September 2024 with $153 million in commitments, nearly three times the prior fund, which lifted assets under management above $300 million. A third-party profile reports six funds and more than $400 million in assets as of June 30, 2025.
The firm backs mid-stage companies that its network of early-stage VC partners brings to it, and it reports more than 1,000 such partners. It does not source cold deals or lead rounds, and it generally does not take board seats. Its AI-related deals include a Series B in Rad AI, an AI platform for radiologists, made with Santa Barbara Venture Partners in 2024. It also backed Pearl, an AI platform for dental x-ray review, in a 2024 round alongside Crosscut Ventures. In 2025 it invested in EliseAI, which automates communications for housing and healthcare organizations. It also joined the $400 million Series B of Generalist AI, a robotics foundation model company led by Radical Ventures, and it lists Decart, a real-time generative AI developer, in its portfolio.
Fund III invests $3 million to $15 million into primary financing rounds. Reporting on the firm's criteria says it favors companies with more than $10 million in revenue, growing about 50% a year and near profitability. Its portfolio and tagged stages center on Series B and later rounds.
