Altss is a fundraising intelligence platform that supplies verified data on family offices and institutional LPs for alternative-investment capital raisers.
Altss operates an OSINT-powered allocator intelligence platform covering family offices, institutional investors, funds, and private companies. It combines regulatory filings, public disclosures, and licensed partner data into verified profiles refreshed within a 30-day cycle, giving fund managers live contact, mandate, and relationship signals rather than static contact lists.
The Miami-based company was founded in 2025 by Dawid Siekiera, a former General Partner at Infinium Venture Studio, after he hit the limits of legacy LP databases while raising capital. Altss is bootstrapped and founder-backed, serves venture, private equity, private credit, and investment banking teams, and sells access on an annual per-seat subscription.
