Caplight secondary marketplace

Caplight’s secondary marketplace combines institutional-grade pricing data and live order flow for pre-IPO companies. Secondary funds, venture capital firms, shareholders, and brokers can discover opportunities, view and inquire about bids and offers, and connect with institutional buyers and sellers. The marketplace includes deal flow from more than 200 independent brokers, company and investor data, and Caplight Connect, which routes interest anonymously until both parties agree to talk. Instant Connect facilitates full trades on the platform. MarketPrice provides daily price points and estimated valuations for actively traded, venture-backed private companies, using funding-round pricing, trade and order data, and other observable signals.
