Funding Brief|Reco Raises $55M Series B Extension, Agent Security Valuation Tops Hundreds of Millions

Sep 30, 20261 min
TL;DRReco closed a $55M Series B extension, with a strategic investment from AT&T Ventures and new backers Forestay and Quadrille Capital, at a valuation the CEO says has 'more than doubled' since February — into the hundreds of millions. The signal: agent security already has at least two dozen competitors, and surviving isn't about discovering agents — it's about turning an existing SaaS security customer base into agent-governance trust.

What the company does

Reco secures AI agents inside the enterprise — helping security teams see which agents are running, what identities and permissions they use, what data and systems they can reach, and revoking access they shouldn't have.

The company started out in SaaS security and expanded its scope last year to cover the entire "agentic ecosystem." Its core technology is the Reco Graph, which maps the relationships among agents, identities, applications, permissions, data, and workflows. CEO Ofer Klein says the shift came because enterprises are building and deploying AI agents faster than they can track them: at one Fortune 100 customer, a single scan turned up 21,000 agents the company didn't know existed; at a large financial services customer, Reco found an agent set up by a former employee that could access Salesforce and leak data to a domain the company couldn't see.

Reco now has more than 100 customers, with financial services accounting for roughly 40% of the business. Annual recurring revenue is in the "double-digit millions," and Klein expects it to triple this year. The platform integrates with more than 280 applications, including OpenAI, Anthropic, Microsoft Copilot, Salesforce, ServiceNow, and Workday.

What this round signals

What it means for the agent ecosystem

Reco's own press release cites Gartner's forecast that the average Fortune 500 enterprise will run more than 150,000 agents by 2028, up from fewer than 15 in 2025 — that gap is exactly what this round is betting on. TechCrunch's coverage the same day pointed out that Crunchbase and PitchBook alone list at least two dozen "agent security" startups, including Air (which vets the tools agents use), Cymphony (which helps companies control what data their agents can reach), and CrowdStrike (building detection and response). The category has entered a crowded phase where every vendor wants to help govern your agents.

What investors are betting on

AT&T Ventures' logic is direct — AT&T is already a Reco customer, so this strategic investment is putting money behind a product it has validated internally. Reco's differentiation is leaning on its existing SaaS security customer base and its 280-plus app integrations, so customers don't have to swap systems just to cover agents. The new entrants, Forestay and Quadrille Capital, are classic growth-stage capital betting that the projected 3x ARR growth actually materializes.

Numbers worth watching

  • Less than eight months after the February Series B, valuation has "more than doubled" and total funding has climbed from $85M to $140M
  • A single customer environment turned up 21,000 unknown agents — concrete evidence of the scale of "agent sprawl"
  • 187 employees (per Tracxn) against double-digit-million ARR is a relatively high revenue-per-employee figure for a security startup, suggesting the product still leans on automated platform detection rather than heavy services

Watchlist status

Reco is not yet on the watchlist. Recommend adding it to section B7 (Agent Security / Governance) alongside Zenity, Hidden Layer, Prompt Security, and Noma Security, with tracking focus on: how fast the Reco Graph extends from SaaS security into agent governance, the customer-endorsement effect of strategic investors like AT&T, and how its positioning compares to recently funded rivals like Cymphony and Air.

Today's takeaway

The real signal in Reco's round isn't the dollar amount — it's the speed of the pivot. A company that started in SaaS security more than doubled its valuation in eight months by extending its existing customer relationships and tech stack into agent governance, which suggests that in the crowded agent-security category, locking down customer trust first beats building technical differentiation first.
