StageOne Ventures closes $165M fifth fund for Israeli AI infrastructure startups
What's the deal? Israeli early-stage VC firm StageOne Ventures has closed its fifth fund at $165 million, pushing its total assets under management past $650 million.
The Tel Aviv-based firm, founded in 2001, will use Fund V to back inception-stage startups in AI infrastructure, cybersecurity, physical AI, agentic orchestration, and vertical AI — sectors where it says Israeli engineering talent holds a strong global edge.
The fund is backed by repeat institutional and private investors from the US, Europe, and Israel. No individual LPs were named.
Why now? The close marks StageOne's 25th anniversary, and it comes as enterprise AI shifts from experimentation to infrastructure build-out — precisely the layer the firm has always targeted. Past funds tracked major platform shifts in enterprise computing, from telecoms to cloud; Fund V is explicitly a bet that AI infrastructure is the next such shift.
StageOne has backed 69 companies to date, with 21 exits. Notable exits include EpsagonDealroom has a profile for this one. Try Dealroom → by Cisco, Cyberint and AvananDealroom has a profile for this one. Try Dealroom → by Check Point, TraffixDealroom has a profile for this one. Try Dealroom → by F5, and GuardiumDealroom has a profile for this one. Try Dealroom → by IBMDealroom has a profile for this one. Try Dealroom →.
What could go wrong? Inception-stage investing in Israel carries outsized geopolitical risk. The firm's own press release acknowledges "global and local uncertainties" — a reference to the ongoing conflict and its effects on talent, capital flows, and deal timelines. A prolonged security situation could hamper the firm's ability to source, fund, and scale companies at the pace Fund V anticipates.
The AI infrastructure market is also attracting fierce global competition. US and European funds are increasingly writing early checks into the same categories, raising the bar for Israeli startups trying to win international customers and follow-on capital.
The signal: StageOne is among the clearest expressions of a thesis gaining momentum in Israel's venture ecosystem: that the country's deep engineering talent is especially well suited to building the unglamorous but essential infrastructure that makes AI systems reliable, secure, and governable at enterprise scale. The fund's focus areas — AI infrastructure, cybersecurity, and agentic orchestration — mirror almost exactly where the largest enterprise software buyers are now spending.
For a firm that has spent 25 years at the earliest stage of each major computing cycle, the $165 million close suggests its LPs believe this cycle will be the biggest yet.
