Information platform giants like Databricks and Snowflake do nice with regards to constructing information pipelines and operating low-latency analytics to generate AI options, however they don’t remedy the necessity for contemporary information and sophisticated compute necessities at AI inference time. That’s in line with Chalk, the AI startup that at this time 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 trade 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 deal with rushing 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 instantly from the supply” at inference time, which eliminates stale information and brittle ETL information pipelines of current AI information platforms whereas additionally enhancing latency.
Over the previous three years, Chalk’s distinctive strategy to AI inference has attracted numerous clients, together with Doppel, Nowst, Sunrun, Whatnot, Socure, Discovered, Medely, and iwoca, amongst others. The San Francisco firm has been notably profitable at serving to clients within the monetary providers trade construct AI inference pipelines.
“Chalk helps us ship monetary merchandise which are extra responsive, extra customized, and safer for thousands and thousands of customers,” acknowledged Meng Xin Loh, a senior technical product supervisor at MoneyLion. “It’s a direct line from infrastructure to influence.”
“Chalk has remodeled our ML growth workflow. We will 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 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, mentioned 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 this time.
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. Particularly, Chalk sees the big information platform like Snowflake and Databricks being vulnerable 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 information and sophisticated computations on the precise second selections are made,” Freed-Finnegan wrote. “Present options have enabled massive, complicated 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 selections. “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 companies that led Chalk’s Sequence A spherical, mentioned that Chalk is poised “to grow to be the Databricks of the AI period.”
“It’s one of many fastest-growing information firms we’ve ever seen,” Senkut acknowledged. “The crew has basically redefined how information strikes via 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 huge scale–one thing that, till now, was thought of out of attain.”
The Sequence A spherical, which included participation by Triatomic Capital and current traders 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 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.
