Straiker

Agent security platform with autonomous red teaming (Ascend AI)

Automated platformAgents and toolsRuntime guardrailsCompliance mapping

Straiker came out of stealth in Mar 2025 with $21M from Lightspeed and Bain Capital Ventures, then raised a $64M Series A in Jun 2026. Ascend AI runs continuous autonomous red teaming of agents before deployment, or one-time risk assessments, and its findings become policies in Defend AI, the runtime product. Discover AI inventories agents and MCP servers.

Best for: Agent builders who want pre-release red teaming tied directly to runtime policy.

$64M Series A (Jun 2026), $85M raised in total
