Information platform giants like Databricks and Snowflake do nice on the subject of constructing information pipelines and working low-latency analytics to generate AI options, however they don’t clear up the necessity for recent information and complicated compute necessities at AI inference time. That’s in response to Chalk, the AI startup that at the moment introduced it has raised $50 million to construct AI inference information pipelines.
Chalk was based in 2022 by three engineers, Marc Freed-Finnegan, Elliot Marx, and Andy Moreland, to develop a real-time information 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 information platform with a particular give attention to dashing up the AI inference course of and delivering entry to “ultra-low latency” information to energy AI apps, resembling detecting identification 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 function pipelines atop a Rust-powered compute engine. This engine then “resolves options immediately from the supply” at inference time, which eliminates stale information and brittle ETL information pipelines of current AI information platforms whereas additionally bettering latency.
Over the previous three years, Chalk’s distinctive method to AI inference has attracted quite a lot of clients, together with Doppel, Nowst, Sunrun, Whatnot, Socure, Discovered, Medely, and iwoca, amongst others. The San Francisco firm has been significantly profitable at serving to clients within the monetary providers business construct AI inference pipelines.
“Chalk helps us ship monetary merchandise which might be extra responsive, extra customized, and safer for tens of millions of customers,” said Meng Xin Loh, a senior technical product supervisor at MoneyLion. “It’s a direct line from infrastructure to impression.”
“Chalk has reworked our ML improvement workflow. We are able to now construct and iterate on ML options sooner 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–crucial for assembly the ultra-high freshness requirements we require.”
When the co-founders began Chalk, they knew real-time inference was crucial for fintech, stated Marc Freed-Finnegan, Chalk’s CEO. “Over time, we’ve found that its significance extends far past fintech–to identification verification, fraud prevention, healthcare, and e-commerce,” he wrote in a weblog publish at the moment.
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 house. Specifically, Chalk sees the big information platform like Snowflake and Databricks being prone to the market’s shift away from AI coaching in direction of AI inference.

“AI compute is shifting quickly from coaching to real-time inference, creating new calls for for recent information and complicated computations on the precise second choices are made,” Freed-Finnegan wrote. “Present options have enabled giant, advanced coaching workflows and have shops (low-latency caches of pre-processed information), however real-time inference stays underserved.”
The CEO says Chalk addresses this hole “by offering infrastructure designed explicitly for instantaneous, clever choices. “Our mission stays clear: to ship intuitive, highly effective information infrastructure that integrates seamlessly with builders’ favourite instruments,” he says.
Aydin Senkut, the founder and managing companion 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 information corporations we’ve ever seen,” Senkut said. “The group has essentially redefined how information strikes by means of the AI stack, a vital development for chain-of-reasoning fashions. What’s much more outstanding is Chalk’s capability to ship 5-millisecond information pipelines at large scale–one thing that, till now, was thought of out of attain.”
The Collection A spherical, which included participation by Triatomic Capital and current buyers Basic 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 outstanding string of venture-fueled development. Because it raked in billions in enterprise cash from 2018 by means 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.
