Knowledge platform giants like Databricks and Snowflake do nice with regards to constructing knowledge pipelines and working low-latency analytics to generate AI options, however they don’t resolve the necessity for contemporary knowledge and complicated compute necessities at AI inference time. That’s in keeping with Chalk, the AI startup that right now 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 methods at startups like Affirm, Haven (acquired by Credit score Karma), and Index (acquired by Stripe), in addition to business giants like Google and Palantir.
The engineers developed the Chalk knowledge platform with a particular deal with rushing up the AI inference course of and delivering entry to “ultra-low latency” knowledge to energy AI apps, corresponding to detecting id theft, qualifying mortgage candidates, boosting vitality 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 function 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 current AI knowledge platforms whereas additionally enhancing latency.
Over the previous three years, Chalk’s distinctive method to AI inference has attracted plenty of 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 providers business construct AI inference pipelines.
“Chalk helps us ship monetary merchandise which might be extra responsive, extra personalised, and safer for thousands and thousands of customers,” said Meng Xin Loh, a senior technical product supervisor at MoneyLion. “It’s a direct line from infrastructure to influence.”
“Chalk has reworked our ML growth workflow. We will now construct and iterate on ML options quicker than ever, with a dramatically higher developer expertise,” said Jay Feng ML Engineer at Nowstaw. “Chalk additionally powers real-time function transformations for our LLM instruments and fashions–vital for assembly the ultra-high freshness requirements we require.”
When the co-founders began Chalk, they knew real-time inference was vital for fintech, stated Marc Freed-Finnegan, Chalk’s CEO. “Through the years, we’ve found that its significance extends far past fintech–to id verification, fraud prevention, healthcare, and e-commerce,” he wrote in a weblog publish right now.
With just a few notches on its AI inference belt, Chalk is now able to scale up operations and make some extra noise within the area. Particularly, Chalk sees the massive 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 giant, 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 accomplice at Felicis, one of many enterprise capital corporations that led Chalk’s Collection 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 said. “The crew has essentially redefined how knowledge strikes by way of the AI stack, an important development for chain-of-reasoning fashions. What’s much more exceptional is Chalk’s means to ship 5-millisecond knowledge pipelines at huge scale–one thing that, till now, was thought of out of attain.”
The Collection A spherical, which included participation by Triatomic Capital and current traders Normal 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 by way of 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 Collection J spherical at a valuation of $62 billion.
Will Chalk ever attain these nice heights? Solely time will inform.
