Fireworks hires former Meta executive Dave Wehner as CFO

Dave Wehner spent years managing the money at one of the largest companies on the planet. His next job is at a startup that is four years old.

Wehner, who most recently served as Meta’s chief strategy officer, is leaving the company to become chief financial officer of Fireworks, an AI startup. He announced the move on X on Friday. It is a notable jump: a seasoned Big Tech finance executive betting his next chapter on a company that did not exist until 2022.

From Menlo Park to the inference business

Wehner’s résumé is about as Meta as it gets. He joined the company in 2012 and took over as CFO in 2014, a role he held until 2022.

After that, he moved into the chief strategy officer seat, where he stayed until this month. That adds up to more than a decade inside a company that grew into one of the most closely watched businesses in tech.

At Fireworks, his mandate is straightforward on paper. CEO Lin Qiao told CNBC in a statement that Wehner will be responsible for scaling the startup’s finances and operations.

The hire also has a bit of a reunion quality. Fireworks was founded in 2022 by former Meta engineers. Qiao herself previously led Meta’s PyTorch team, which built one of the most widely used frameworks for developing machine learning models.

What Fireworks actually does

Fireworks operates in AI inference. Think of an AI model like a chef who has already gone through culinary school. Training is the schooling. Inference is the part where the chef actually cooks meals for paying customers, over and over, as fast and cheaply as possible.

More specifically, Fireworks trains and serves open-source AI models built for enterprise use. Its pitch centers on letting businesses take open models and customize them with their own proprietary data, rather than relying solely on closed models from the biggest labs.

The volume is substantial. Fireworks processes more than 40 trillion tokens every day, with most of that traffic coming from models its clients have customized. A token is a small chunk of text, roughly a word or part of a word, so that figure represents an enormous amount of AI-generated output flowing through its systems daily.

The customer list includes names like Uber, Shopify, and Doximity. Those are companies with large amounts of their own data and clear reasons to want models tuned to their specific needs.

The numbers behind the hire

Fireworks’ financial trajectory explains why it needed a heavyweight CFO.

In July 2026, the company raised $1.505 billion in a Series D round. That deal valued Fireworks at $17.5 billion on a post-money basis, meaning the valuation includes the fresh cash from the round.

Revenue has been moving even faster than the fundraising headlines. By mid-2026, Fireworks hit a $1 billion annualized revenue run rate. It got there after climbing from $100 million in annualized revenue in approximately 16 months.

Annualized revenue run rate, for the uninitiated, takes current revenue over a short window and projects it across a full year. It is a useful snapshot of momentum, though it assumes the current pace holds, which is not guaranteed.

Why a former Meta CFO matters here

Hiring someone who ran the finance function at Meta for eight years is one way to address that gap. Wehner has experience with financial planning, investor relations, and capital allocation at a scale few executives can match.

For Fireworks, the immediate value is likely operational. A business processing tens of trillions of tokens a day has serious infrastructure costs, and managing compute spending against revenue growth is the kind of balancing act that separates durable AI companies from expensive experiments.

What this means

For the AI industry, the move is a signal about where executive talent sees opportunity. Wehner had a senior post at one of the world’s most valuable tech companies. He chose to leave it for an inference startup, which says something about how seriously insiders view the business of serving models, not just building them.

For Meta, the departure removes a long-tenured executive who helped steer its finances through a major chapter of growth. The company has not lost a sitting CFO, since Wehner had already moved into the strategy role, but it does lose a figure with deep institutional knowledge.
