vs Last Round — unlabeled: the secondary share price against the round's price per share (the tape's own comparison). print: the latest observed print's implied valuation against the last priced round's post-money. mark: the valuation shown against that post-money — no independent print yet. = last round means the two legs are within 0.5%; for a mark basis that means the valuation shown was set by the round itself. A cell that says no priced round on record has a secondary price but no round to test it against — it is never rendered as 0.
Ranked by tracked Developer Tools portfolio companies — counted from disclosed round participation and each firm's notable holdings, so a firm only appears here if it actually holds companies in this ranking. Full capital-side ranking: Top Private Market Investors by AUM.
By latest disclosed valuation, the largest tracked private Developer Tools companies are DeepSeek ($60B), Cognition ($48B), Moonshot AI ($35B), Reflection AI ($25B), Fireworks AI ($18B). The full ranking of 111 companies refreshes daily at quantlogix.ai/private/developer-tools.
Ranked by tracked Developer Tools portfolio companies, the most active investors are Y Combinator (11 tracked), Sequoia Capital (9 tracked), Andreessen Horowitz (9 tracked), Lightspeed Venture Partners (7 tracked), Index Ventures (6 tracked). Full ranking: Top Private Market Investors by AUM.
Valuations are each company's latest disclosed mark, dated per row; secondary share prices refresh daily (34 of 111 tracked companies currently carry one). Rows without a usable number say so rather than showing zero.
Methodology. Rankings are by each company's latest disclosed valuation (roster + weekly enrichment); the "mark" chip shows when that valuation was set. Secondary share prices are point estimates from secondary-market activity — one implied price per name, no bid/ask — refreshed daily (marks overlay as of 2026-10-01), each carrying its own date. "vs Last Round" compares the secondary price to the company's own last primary round per-share price; rows without a usable comparison say so rather than showing zero. Companies marked acquired, defunct, or public are excluded. Educational data, not investment advice.
