Flapping Airplanes' $1B Series A, and Meta's new share class to fund AI

Covers roughly midday Oct 21 to 5am ET Oct 22, plus three Oct 20–21 rounds our Oct 21 issue missed (marked "catch-up"). Every round below is confirmed by the company or its lead investor. Figures the companies report about themselves (ARR, customer counts, benchmarks) are labeled company-reported.

The year-old San Francisco research lab, which works on training AI with far less data and compute, raised a $1B Series A co-led by Index Ventures and Lux Capital. Index confirmed it led the round and said partner Mark Xu is joining the board (Index Ventures). The company's site now lists "a $180M seed round and a $1B Series A" (Flapping Airplanes). Sequoia, GV and Kleiner Perkins also invested (TechCrunch). The company hasn't disclosed a valuation. Bloomberg reports $6B (Bloomberg), and TechCrunch says the seed priced the company at $1.5B nine months ago. Why it matters for investors: If Bloomberg's number holds, a team of a couple dozen people with no commercial product went to $6B by betting that compute and data will run short before demand does. Research-stage labs selling "more from less" now draw $1B rounds. NVIDIA is on its backer list (per the company site), so even the main seller of compute is backing the efficiency bet. For seed and Series A investors, the likelier opportunity is the people these neolabs train and who later leave to start companies, not the labs themselves.

Meta's Q3 revenue rose 26% to $64.60B. Capex, including finance-lease principal, was $34.91B, against $32.79B of operating cash flow, so free cash flow was negative $2.12B. Meta narrowed its 2026 capex outlook to $135–145B (from $130–145B). Its board also approved a new non-voting Class C stock, intended for Nasdaq listing, effective Jan 19, 2027, to be issued as a one-for-one stock dividend. The company names "capital raising" first among its uses, along with employee pay and acquisitions, and keeps Mark Zuckerberg's voting control intact. Long-term debt stood at $80.92B on Sept. 30, up from $58.74B at the end of 2025. Note that Q3 costs include a $9.89B legal charge. Meta Q3 2026 release Why it matters for investors: In Q3, one of the largest buyers of AI infrastructure spent more on capex than its operations brought in, and it has borrowed more and built a way to sell equity without giving up control. The hyperscaler demand behind AI infrastructure startups' revenue now depends partly on capital markets, not just on cash flow. When a deck projects hyperscaler demand, ask how it fares if capex budgets flatten in 2027.

French AI business-planning platform Pigment raised $250M at a $2.3B valuation. The Scaleup Europe Fund, managed by EQT, led, with WIL (World Innovation Lab), existing investors Greenoaks, ICONIQ, IVP and Meritech, and a planned investment from NVIDIA. Pigment says it passed $100M ARR earlier this year, doubling again year over year, and that 85% of new metrics on its platform are now created by an AI agent (both company-reported). Pigment · Sifted Why it matters for investors: At $2.3B against a $100M-plus ARR figure, Pigment is priced at no more than about 23x ARR. Legora was priced at no more than about 44x its $200M-plus ARR on Wednesday. On these two data points, systems of record that are adding agents are getting about half the multiple of agent-first vertical leaders. Also new: a Europe-focused growth fund that pools public and private capital (it targets €5B, per Pigment's release) is now leading late-stage AI rounds, giving European scale-ups an alternative to US crossover funds.
