Storm Ventures Research
Investment Thesis
Storm Ventures is an early-stage venture capital firm focused exclusively on B2B enterprise software. Founded in the early 1990s and headquartered in Menlo Park, California, the firm has spent over three decades building enterprise leaders across North America, Europe, and Asia. Their core thesis is that the best enterprise companies emerge from teams combining deep technical excellence with exceptional go-to-market execution.
The firm employs a distinctive "paddling to surfing" growth methodology — the belief that catching the right market wave enables compounding scale after the hard work of finding product-market fit. Storm's investment view is encapsulated in the phrase: "the interface layer will disappear. The infrastructure layer will compound," reflecting a strategic emphasis on foundational enterprise technology that becomes more valuable over time.
Storm targets companies with early revenue signals — typically a few hundred thousand dollars in ARR — as evidence of product-market fit before investing. They have successfully partnered with founders navigating the journey from inception to $100M+ ARR, drawing on insights from their "Survival to Thrival" book series on building enterprise leaders.
Sector Focus
Storm focuses on several key enterprise software verticals:
AI-Native Enterprise Software: The firm has aggressively moved toward AI-first companies across all enterprise verticals, particularly LLM applications for sales automation, HR intelligence, security operations, and data infrastructure. Blog essays like "AI Is Eating SaaS" (April 2026) and "AI in B2B SaaS: What's Changed in Two Years?" reflect deep thesis conviction in AI transforming enterprise software.
Cybersecurity: One of Storm's strongest verticals with notable portfolio companies spanning mobile security (MobileIron, acquired by Ivanti), application security (Heeler Security), confidential computing (Opaque), data governance (Dasera, acquired by Netskope), browser security (Seraphic Security, acquired by CrowdStrike for ~$400M in January 2026), cyber threat intelligence (Digital Shadows, acquired by ReliaQuest), and MDR (AirMDR).
Enterprise SaaS: Core vertical SaaS investments in automotive (Tekion), construction AI (Datagrid, acquired by Procore in January 2026), life sciences quality management (Carta Healthcare), government and legal tech (NextRequest, Logikcull), and remote desktop (Splashtop).
Developer Tools & Infrastructure: Observability and production monitoring (Honeycomb), DevOps automation (System Initiative), enterprise voice/video APIs (SignalWire), AI search (Algolia), and testing automation (Rainforest).
HR & Workforce Technology: Strong track record in talent management, performance coaching, and workplace tools including Talview, SucceedSmart, Praisidio, Modo Labs, Classum, and Blind.
Marketing Technology: Account-based marketing (Demandbase), communication analytics (Onclusive), AI marketing (Blueshift), and attribution (Airbridge180).
Stage Focus
Storm Ventures primarily invests at pre-seed, seed, and Series A, with selective follow-on participation through Series B:

- Series A: Scaling companies with demonstrated growth patterns
- Series B: Selective follow-on investments for existing portfolio companies
The firm describes itself as an "early stage investor" and "the first institutional investor" for many portfolio companies.
