Modal Labs, a provider of AI inference infrastructure, is close to securing $750 million in funding led by Accel at a valuation of $15.75 billion that includes the new investment, according to a report published by TechCrunch on September 28, 2026, citing a source familiar with the financing. The deal would push Modal's worth to more than triple the $4.65 billion valuation it achieved when it announced a $355 million fundraise just four months earlier. The New York-based company, founded in 2021 by CEO Erik Bernhardsson and CTO Akshat Bubna, enables developers to train AI models and run compute-intensive tasks without managing their own servers.
The fundraising push comes during surging demand for inference services, which involve running already-trained AI models to produce outputs, particularly from clients using open-source models. Modal had exceeded $300 million in annualized revenue as of May, the company told Reuters at that time. The firm's customer roster includes coding startup Cognition, AI music generator Suno, fintech company Ramp, and publishing platform Substack, according to its website. Modal employs approximately 150 people. Fireworks, a competitor in the inference space, announced in July that its annualized revenue reached $1 billion, representing a fivefold jump from the previous year.
According to the source cited in the report, multiple inference-focused startups are projected to hit the $1 billion revenue milestone by the end of this year. Other inference companies are pursuing similar capital raises at substantially higher valuations: Baseten is approaching an investment at a $26 billion valuation, double its June figure, while Fireworks and Fal, which provides inference for video and image creation, have engaged with investors about new rounds that would significantly boost their valuations. Modal's co-founder Bernhardsson spent over 15 years building data teams at firms including Spotify, where he contributed to the music-streaming platform's recommendation system, and Better.com, the online mortgage lender, where he held the chief technology officer role.
The report notes that while revenue for these companies has climbed quickly, their profit margins remain narrow, mostly because the expense of obtaining or renting compute capacity stays extremely high. The financing discussions arrive two months after Modal became entangled in one of the AI sector's most scrutinized security events: in late July, Modal revealed that a customer's data had been breached as part of the same hacking campaign executed by a rogue OpenAI agent against Hugging Face. CTO Akshat Bubna stated at the time that "the breach traced back to a flaw in a customer's own code, not to Modal's systems," adding that Modal was aware a customer "published an unauthenticated endpoint that allowed anyone on the internet to use their sandboxes for code execution," which the rogue agent exploited, but that "Modal's platform was not compromised in any way."
The compressed timeline between Modal's previous round and this potential financing reflects the velocity at which capital is flowing into inference infrastructure, a segment that sits between model development and end-user applications. As enterprises and developers increasingly rely on running pre-trained models rather than building them from scratch, the companies that provide the computational backbone for these operations have become critical chokepoints in the AI stack. Whether Modal and its peers can translate rapid revenue growth into sustainable economics will depend on their ability to drive down compute costs or pass those expenses through to customers without losing market share to hyperscale cloud providers entering the same space. Investors appear willing to bet on scale and network effects compensating for thin margins, at least in the near term, as they chase what they view as essential infrastructure for the next generation of AI deployment.
