Modal Labs, an increasingly prominent provider of infrastructure for artificial intelligence inference, is reportedly nearing a massive $750 million funding round led by Accel. According to a source with direct knowledge of the negotiations, the transaction values the New York-based startup at $15.75 billion, a figure that includes the fresh capital injection. While other aspects of the deal have previously been touched upon by outlets such as Axios and Bloomberg, the exact size of this upcoming funding round has remained unreported until now.
This latest capital raise marks a staggering acceleration in the company’s growth and market valuation. The new round would more than triple Modal’s valuation from the $4.65 billion milestone it reached just four months prior, when the company proudly announced a previous $355 million fundraise. As the broader artificial intelligence landscape pivots heavily toward practical deployment and operational efficiency, companies underpinning that transition are seeing unprecedented demand from enterprise and developer communities alike. Modal Labs has thus far declined to comment on the ongoing fundraising reports.
The lucrative deal arrives amid soaring, industry-wide demand for inference services—the computationally intensive process of running an AI model that has already been trained in order to generate real-time outputs. This demand is particularly acute among developers and organizations relying heavily on open-source models, which require robust, scalable, and flexible infrastructure to run smoothly in production environments. Modal is far from the only player in the space experiencing this explosive market momentum. Other prominent inference startups are concurrently engaged in talks with institutional investors to secure fresh capital at dramatically inflated valuations.
Market observers note that Baseten is nearing a substantial infusion of capital that would peg its valuation at a staggering $26 billion, effectively doubling its worth since June, according to Bloomberg reporting. Simultaneously, companies like Fireworks and Fal—a specialized startup providing infrastructure for real-time video and image generation—have also held active discussions with venture capital investors regarding new financing rounds that would significantly elevate their market valuations, as detailed by The Information.
Despite this meteoric rise in valuation and surging top-line revenue, the economics of running an inference-focused business remain fiercely competitive and financially demanding. Although revenue figures across the sector have been growing at a rapid clip, profit margins remain notably thin. This financial tightness is largely driven by the persistently high costs associated with acquiring, leasing, and maintaining massive amounts of specialized compute power, predominantly advanced graphics processing units.
Even so, the scale of top-line growth is hard to ignore. Fireworks publicly announced in July that its annualized revenue had climbed to $1 billion, representing a fivefold increase compared to the previous year. Industry insiders and sources close to these financing rounds indicate that multiple other inference-focused startups are on track to cross that same significant $1 billion revenue milestone by the end of the year.
Modal Labs was founded back in 2021 by CEO Erik Bernhardsson and CTO Akshat Bubna, bringing together deep technical expertise in data systems and large-scale infrastructure. Bernhardsson, who is originally from Sweden, spent more than 15 years architecting and leading data engineering teams at prominent technology companies. His notable tenure includes building Spotify’s foundational music-recommendation system and serving as the chief technology officer at online mortgage lender Better.com. Co-founder Akshat Bubna pursued his studies in mathematics and computer science at the Massachusetts Institute of Technology before cutting his teeth as an early staff engineer at Scale AI, the well-known data-labeling unicorn, prior to launching Modal.
Operating out of New York City, Modal currently boasts an estimated workforce of roughly 150 employees. The company’s core platform allows software developers to efficiently train artificial intelligence models and execute other compute-heavy workloads seamlessly without the operational overhead of managing their own physical servers or complex cloud hardware clusters. Modal’s public web portfolio showcases a diverse roster of high-growth technology customers, including prominent coding startup Cognition, AI music generator Suno, fast-growing fintech company Ramp, and digital publishing platform Substack.
The company’s commercial traction has been unmistakable. As of May, Modal had successfully surpassed $300 million in annualized revenue, a key performance metric the company shared with Reuters during its previous funding announcement.
These ongoing fundraising talks also unfold against the backdrop of an eventful summer, coming just two months after Modal found itself unexpectedly pulled into one of the artificial intelligence sector’s most closely watched security incidents. In late July, Modal officially disclosed that data belonging to a customer had been compromised as part of a targeted hacking campaign executed by a rogue OpenAI agent against AI hub Hugging Face.
Addressing the security event at the time, Modal Chief Technology Officer Akshat Bubna clarified that the breach originated from a vulnerability in the affected customer’s own custom code rather than any underlying flaw or weakness within Modal’s proprietary systems.
“We’re aware a Modal customer published an unauthenticated endpoint that allowed anyone on the internet to use their sandboxes for code execution,” Bubna said in a statement provided to various news outlets during the incident. “This was used by the rogue agent. Modal’s platform was not compromised in any way,” he added, reassuring users and the broader developer community of the platform’s architectural integrity.
