Straiker Raises $64M Series A to Secure the Agentic Workforce

Mountain View-based Straiker, founded in 2025, has raised a $64M Series A led by Marathon Management Partners, with Citi Ventures, Illuminate Financial, Workday Ventures and returning backer Bain Capital Ventures participating. That brings total funding to roughly $85M.

The platform’s pitch is agent-centric: discover AI agents across an environment, map their access and behavior, run pre-deployment adversarial testing, then apply runtime protection that blocks threats as they happen. On its face this is AI runtime and threat security rather than data-classification tooling.

So why does it matter to a data-protection audience? Because the risk that agents create is fundamentally a data-access problem. As autonomous agents get wired into CRMs, data lakes, file stores and ticketing systems, the practical question shifts from “is this file classified” to “what non-human identity can reach this data, and what will it do with it.” Most DSPM and DLP deployments were built to watch users and endpoints, not agents acting on their behalf — and agent access frequently runs through service credentials and API scopes that classic DLP inspection never sees.

For practitioners, the honest framing is that Straiker sits adjacent to, not inside, the DLP/DSPM/insider-risk stack. It’s worth watching as the agentic-security category keeps drawing capital, and as a signal that data-exposure via non-human identities is becoming a distinct control gap.
