Portal26, a GenAI governance platform, just closed a $9 million Series A led by Shasta Ventures. Fusion Fund and a Fortune 500 financial services company also invested, bringing total funding to $15 million since 2022.
The problem Portal26 solves is simple but urgent: employees are secretly uploading sensitive company data into ChatGPT, Claude, and other public AI tools. Companies have no visibility into this “Shadow AI” activity, creating massive legal and security exposure.
What Portal26 Does?
The platform detects all generative AI tools employees use—licensed, private, or public—in real-time. It analyzes prompts and flagged content, then blocks risky activity automatically.
This matters because GenAI outputs are now legally discoverable evidence after the 2024 Tremblay v. OpenAI case.
Beyond security, Portal26 extracts business value: it identifies which AI use cases boost productivity, tracks ROI across different tools, and enables compliance reporting.
Why Investors Backed Portal26 Now?
Enterprise GenAI adoption is exploding, but governance lags far behind. Larger players are noticing—CrowdStrike acquired AI governance startup Pangea for ~$260 million in September 2025, signaling serious venture interest in this category.
Portal26's timing is strong. The company already has multi-year enterprise contracts, heavy customer trust, and established partnerships across security, systems integrators, and major cloud platforms.
Arti Raman, Portal26's CEO, spent over 20 years in cybersecurity and risk management at Symantec before founding the company in 2022.
