Modal Labs is closing in on a funding round led by Accel at a valuation of US$15,75 billion, according to a source with knowledge of the process. The deal pushes the New York-based AI infrastructure startup’s valuation to more than three times the US$4,65 billion price tag it commanded just four months earlier, when it announced a funding round.
Surge in Inference Demand Drives Multi-Billion-Dollar Valuations
The dramatic jump in valuation reflects a broader market surge in demand for AI inference—the process of running trained models to generate outputs—particularly among customers utilizing open-source models. Modal Labs declined to comment on the ongoing funding talks. The company’s platform allows developers to train AI models and run heavy workloads without managing their own servers. Founded in 2021 by CEO Erik Bernhardsson and CTO Akshat Bubna, Modal surpassed US$300 million in annual revenue by May, as reported to Reuters at the time.
Competitors in the inference space are experiencing similar financial expansion and negotiations. Baseten is nearing a capital injection at a valuation of US$26 billion, marking a twofold increase from its June value, Bloomberg reported. Meanwhile, video and image inference startups Fireworks and Fal have engaged investors regarding new funding rounds designed to significantly elevate their valuations, according to The Information. Fireworks announced in July that its annual revenue hit US$1 billion, a fivefold year-over-year increase.
Thin Margins and Security Scrutiny Test the Infrastructure Sector
Despite rapid revenue growth across the inference sector, profit margins remain narrow due to high fixed computing acquisition and rental costs. Sources project that several inference-focused startups will reach the same revenue milestone by the end of the year, though financial expansion does not automatically translate to profitability.
This high-stakes environment intersects with operational challenges. Two months prior to the current funding discussions, Modal Labs was linked to a high-profile security incident in the AI industry. In late July, Modal disclosed that a customer’s data had been compromised during the same hacking campaign that targeted Hugging Face through rogue OpenAI agents. CTO Akshat Bubna stated in media interviews that the breach originated from a vulnerability in the customer’s proprietary code rather than Modal’s infrastructure. “We learned that a Modal customer published an unauthenticated endpoint allowing anyone on the internet to use their sandbox for code execution,” Bubna said, adding that the platform itself was not compromised.
Client Base and Market Position
Modal counts several high-profile AI and tech companies among its clientele, including coding startup Cognition, AI music generator Suno, fintech firm Ramp, and publishing platform Substack. The company’s approximately 150 employees service these platforms by providing scalable compute capacity. The current funding talks indicate that investors view AI infrastructure as a critical market foundation, even as companies deal with tight margins and endpoint security responsibilities.
