WitnessAI announced a $58 million strategic funding round on Jan. 13, 2026 to support global expansion. The company said the AI security platform is trusted by leading enterprises and is adding new ways to secure AI agents.
WitnessAI says its platform gives enterprises visibility, control, and guardrails across AI tools and agents. The company positions the product as a “confidence layer” for enterprise AI to reduce leakage, compliance, and prompt-injection risk.
Ballistic Ventures said WitnessAI was launched from stealth with $27.5 million in Series A funding, signaling early investor conviction. The company targets the fast-growing enterprise need to govern chatbots, copilots, and AI agents without exposing sensitive data.

Yes. Accredited investors can indicate interest in WitnessAI shares through UpMarket by filling out the form on this page or creating an account at upmarket.co. All pre-IPO offerings are subject to availability and require a $50,000 minimum investment. UpMarket is a FINRA-registered broker-dealer and has brokered alternative investments since 2019.
Pre-IPO investments carry significant risks. WitnessAI shares are illiquid, meaning there is no public market to sell them quickly. There is no guaranteed exit timeline or return. The investment is speculative in nature, and investors should be prepared for the possibility of total loss. Valuations of private companies can fluctuate substantially between funding rounds. Investors should consult their financial advisor and review all offering documents before investing.
In a pre-IPO transaction, accredited investors purchase shares from existing shareholders (such as employees, early investors, or other holders) through secondary market platforms. The company itself does not issue new shares in these transactions. UpMarket facilitates these trades as a FINRA-registered broker-dealer, handling compliance, documentation, and settlement on behalf of both parties.
There are two primary exit paths for pre-IPO holdings: selling your shares on the secondary market to another buyer, or holding until the company completes an IPO or is acquired. Both paths are subject to transfer restrictions, company approval (right of first refusal), and market conditions. The timing of any exit is unpredictable, and investors should plan for a multi-year holding period.
The minimum investment for most pre-IPO offerings on UpMarket is $50,000. This amount may vary depending on the specific offering and share availability. There are no fees to create an UpMarket account or browse available investments. Investors only pay transaction-related fees when they complete an investment.
UpMarket's valuation estimate of is derived from a proprietary model that incorporates multiple data sources: funding round data (Caplight), revenue estimates (Sacra), secondary market pricing, and public company comparables. The model applies a private company discount to the public comp multiple to account for illiquidity and information asymmetry. This estimate is not investment advice and may differ substantially from the price at which shares actually trade.
