SI Ventures

SI Ventures is a Fort Myers, Florida-based venture capital firm founded in 1996 as the venture capital affiliate of Gartner Group (now Gartner, Inc.) in partnership with private-equity firm General Atlantic. That founding structure gave SI Ventures a rare differentiator: portfolio companies could tap Gartner's research platform — more than 1,000 analysts and direct reach into over 1 million IT professionals — as a competitive due-diligence and go-to-market accelerant unavailable to founders backed by purely financial VCs. The firm invested primarily at Series B and Series C in US enterprise technology companies across information technology, communications infrastructure, semiconductors, security, alternative energy, and software applications. Fund III alone targeted $350 million to $450 million in committed capital. Across its history, SI Ventures made approximately 37 investments, with top-sector concentrations in enterprise applications and communications. The portfolio has produced 1 IPO and 5 acquisitions: Skillsoft listed on the NYSE in July 2019; RelayHealth, Inceptor, OpenNetwork Technologies, and TruSecure were acquired; and Brainshark was acquired by Bigtincan for $86 million in August 2021 — the fund's most recently disclosed portfolio exit. SI Ventures built a team of approximately nine professionals including five partners across multiple funds. The firm's Gartner affiliation positioned it uniquely at the intersection of research credibility and growth-stage capital, enabling portfolio companies to validate their market positioning with the world's leading IT research organization while simultaneously accelerating enterprise customer acquisition.
