Why Investors Are Watching Prove
Growth Signal
Private markets still reward select high-growth software names
SVB said nearly $350B flowed into U.S. venture deals in 2025, even as VC fundraising fell to a seven-year low. That backdrop suggests Prove can still attract capital if it shows durable revenue growth and efficient scaling.
Market Opportunity
Private markets are replacing public markets for growth exposure
a16z noted that across public software, internet, and fintech, fewer than 5 companies are expected to grow above 30% in 2026. That scarcity makes private tech companies like Prove more relevant for investors seeking growth.
Competitive Moat
Access to concentrated private-tech capital remains a moat
Altra said it builds concentrated exposure to top private tech companies through creative structures such as equity swaps and co-investment partnerships. For Prove, that kind of financing ecosystem can support follow-on growth and signal investor confidence.

No. As of March 2026, Prove is a private company and does not trade on any public stock exchange. Accredited investors can access Prove shares through UpMarket, a FINRA-registered broker-dealer that specializes in pre-IPO investments.

Yes. Accredited investors can indicate interest in Prove 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 more than $500M in alternative investments since 2019.
Pre-IPO investments carry significant risks. Prove 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.
Prove provides digital identity verification and authentication for 1,000+ companies worldwide and is valued at $6.8B, as private markets still reward select high-growth software names — accredited investors can access Prove stock through UpMarket.
