What it claims
HiddenLayer announced on 2 September 2026 a $100 million Series B led by Delta-v Capital, with participation from Ten Eleven Ventures, Morgan Stanley, M12 (Microsoft’s venture fund) and Booz Allen Ventures. Secondary coverage puts total raised at roughly $150M following a ~$50M Series A about three years earlier. The release states the funds will “deepen its enterprise platform, including its Agentic Runtime Security capabilities, and Agent Harness Security” (the coding-agent product launched 3 Aug 2026), deepen channel relationships and expand internationally.
Performance claims (vendor-asserted): annual recurring revenue grew “more than 10x” and the company signed “more than 50 new platform customers, including some of the largest names in securities brokerage, banking, insurance, accounting, government, technology, IT services, pharmaceuticals, airlines, and the US defense and intelligence communities” — sectors described, no customer named. The release also restates the recent appointment of Mike Gesnaldo as CRO (see S-2026-08-12-hiddenlayer-cro-gesnaldo).
TechCrunch adds, from its own interview, that “Financial services and large tech companies building AI products are currently the company’s largest verticals”, that it holds Department of Defense and intelligence-community contracts, and that it “plans to expand into Europe and EMEA”.

What’s speculative vs. asserted
Asserted and corroborated: round size, lead and participating investors, announcement date, use-of-proceeds headings.
Vendor-asserted, unverified: 10x ARR growth; 50+ new customers and the sector list; “trustworthy AI” framing. FS being the largest vertical is TechCrunch’s report of the company’s own statement.
Notably absent: no named customer; no regulatory standard (EU AI Act, NIST AI RMF, ISO 42001, DORA) named in either source; no EU/UK entity or data-residency commitment described alongside the EMEA expansion intent.
Topics this feeds
- HiddenLayer — funding, investor base, stated FS concentration and EMEA expansion.
- AI Governance Platforms — capitalisation of the AI-runtime-security cohort; consistent with the Gartner consolidation forecast S-2026-08-26-gartner-securing-ai-forecast.
Open questions raised
- Which regulated-FS firms are among the “largest names in securities brokerage, banking, insurance” — none named; the vault’s standing gap (no named EU/UK regulated-FS reference) persists.
- What the EMEA expansion means for EU data residency of runtime telemetry and for DORA ICT third-party contracting — unaddressed.
- Whether Morgan Stanley’s participation is a strategic (customer) or purely financial investment — not stated.
