Knowledge platform giants like Databricks and Snowflake do nice relating to constructing knowledge pipelines and operating low-latency analytics to generate AI options, however they don’t clear up the necessity for contemporary knowledge and complicated compute necessities at AI inference time. That’s in response to Chalk, the AI startup that in the present day introduced it has raised $50 million to construct AI inference knowledge pipelines.
Chalk was based in 2022 by three engineers, Marc Freed-Finnegan, Elliot Marx, and Andy Moreland, to develop a real-time knowledge platform for AI inference. The trio had expertise constructing AI techniques at startups like Affirm, Haven (acquired by Credit score Karma), and Index (acquired by Stripe), in addition to business giants like Google and Palantir, and noticed a wider want for higher AI inference techniques.
The engineers developed the Chalk knowledge platform with a particular concentrate on dashing up the AI inference course of and delivering entry to “ultra-low latency” knowledge to energy AI apps, reminiscent of detecting id theft, qualifying mortgage candidates, boosting power effectivity, and moderating content material.
Builders work together with the Chalk platform by declaring machine studying options in Python, which is then executed in parallel characteristic pipelines atop a Rust-powered compute engine. This engine then “resolves options instantly from the supply” at inference time, which eliminates stale knowledge and brittle ETL knowledge pipelines of present AI knowledge platforms whereas additionally bettering latency.
Over the previous three years, Chalk’s distinctive strategy to AI inference has attracted various prospects, together with Doppel, Nowst, Sunrun, Whatnot, Socure, Discovered, Medely, and iwoca, amongst others. The San Francisco firm has been notably profitable at serving to prospects within the monetary companies business construct AI inference pipelines.
“Chalk helps us ship monetary merchandise which can be extra responsive, extra customized, and safer for hundreds of thousands of customers,” acknowledged Meng Xin Loh, a senior technical product supervisor at MoneyLion. “It’s a direct line from infrastructure to affect.”
“Chalk has reworked our ML growth workflow. We are able to now construct and iterate on ML options sooner than ever, with a dramatically higher developer expertise,” acknowledged Jay Feng ML Engineer at Nowstaw. “Chalk additionally powers real-time characteristic transformations for our LLM instruments and fashions–important for assembly the ultra-high freshness requirements we require.”
When the co-founders began Chalk, they knew real-time inference was important for fintech, stated Marc Freed-Finnegan, Chalk’s CEO. “Over time, we’ve found that its significance extends far past fintech–to id verification, fraud prevention, healthcare, and e-commerce,” he wrote in a weblog submit in the present day.
With a couple of notches on its AI inference belt, Chalk is now able to scale up operations and make some extra noise within the house. Specifically, Chalk sees the big knowledge platform like Snowflake and Databricks being prone to the market’s shift away from AI coaching in the direction of AI inference.

“AI compute is shifting quickly from coaching to real-time inference, creating new calls for for contemporary knowledge and complicated computations on the actual second selections are made,” Freed-Finnegan wrote. “Current options have enabled massive, complicated coaching workflows and have shops (low-latency caches of pre-processed knowledge), however real-time inference stays underserved.”
The CEO says Chalk addresses this hole “by offering infrastructure designed explicitly for instantaneous, clever selections. “Our mission stays clear: to ship intuitive, highly effective knowledge infrastructure that integrates seamlessly with builders’ favourite instruments,” he says.
Aydin Senkut, the founder and managing associate at Felicis, one of many enterprise capital companies that led Chalk’s Sequence A spherical, stated that Chalk is poised “to change into the Databricks of the AI period.”
“It’s one of many fastest-growing knowledge firms we’ve ever seen,” Senkut acknowledged. “The group has essentially redefined how knowledge strikes via the AI stack, a vital development for chain-of-reasoning fashions. What’s much more exceptional is Chalk’s capability to ship 5-millisecond knowledge pipelines at huge scale–one thing that, till now, was thought-about out of attain.”
The Sequence A spherical, which included participation by Triatomic Capital and present traders Common Catalyst, Uncommon Ventures, and Xfund, valued Chalk at $500 million. That’s about what Databricks was valued round 2017, simply earlier than the corporate embarked upon a exceptional string of venture-fueled progress. Because it raked in billions in enterprise cash from 2018 via 2024, Databricks’ annual recuring income additionally grew, from about $100 million in 2018 to about $3 billion in ARR on the finish of 2024, when the corporate introduced in a whopping $10 billion Sequence J spherical at a valuation of $62 billion.
Will Chalk ever attain these nice heights? Solely time will inform.
