On November 7, 2026, Meta chief strategy officer Dave Wehner announced on X that he is leaving Meta to become chief financial officer of Fireworks, an AI inference startup. CNBC and The Information reported the move the same day. It is the most closely watched move yet this year of a Big Tech executive into an AI infrastructure startup: a man who spent 14 years at Meta, running finance and then strategy, has decided to manage the money at a company only four years old.
What Fireworks offers a former CFO
Founded in 2022 by former Meta and Google employees, Fireworks provides inference and training services for open models, helping developers and companies customize, train and run open models quickly. Its customers include Cursor, Perplexity and Uber. In July 2026, the company closed a $1.505 billion Series D round at a $17.5 billion valuation; by mid-year, annualized revenue had reached the $1 billion mark and it was processing more than 40 trillion tokens a day. In September, it also published a code benchmark of DeepSeek V4.1 Flash. Founder and CEO Lin Qiao told CNBC that Wehner's job is to scale the company's finances and operations.
Wehner's resume is exactly what Fireworks is missing
Wehner joined Facebook in 2012, became chief financial officer in 2014, and moved into the newly created chief strategy officer role in November 2022, a tenure that spanned Meta's transformation into an AI company. Fireworks is growing fast, but it also has messes to clean up: in October, the company disclosed a security incident in which an unauthorized third party used internal credentials to access environment variables in evaluation jobs on a small number of customer accounts. At the same time, reports say it is in talks for a new funding round that could value it at $30 billion to $40 billion. A person who has lived through a public company's financial discipline and full capital-market cycles is exactly what a company at this stage needs.
What it means for Meta and for Fireworks
For Meta, the departure removes a veteran who knew the company's finances and strategy inside out, and no successor has been named. But the exit of a strategy chief does not by itself change Meta's AI investment direction: on November 5, Meta acquired Conductor, continuing to bring multi-agent coding tools in-house. For Fireworks, the appointment reads as a public statement: it is no longer just a technically strong inference provider, but is filling the finance and governance gaps ahead of larger fundraising and expansion. Its valuation story still lives entirely in the private market, and the company has announced no IPO plans.
Neither side has said when Wehner formally starts. Two things are worth watching next: whether Fireworks closes its new round and whether the valuation reaches $30 billion, and whether Meta promotes from within or hires from outside for its next strategy chief.
