Chalk is a feature engineering platform that allows ML teams to define real-time and batch features in Python and serve them with sub-millisecond latency for production inference.
Chalk is a machine learning infrastructure company founded in 2021 by former Google and Stripe engineers, raising $26M to build a developer-friendly feature engineering platform. The platform allows data scientists and ML engineers to define features as Python functions that Chalk automatically computes, caches, and serves with millisecond latency for real-time model inference. Chalk handles the complexity of managing feature freshness across multiple data sources, computing features on-demand or through scheduled batch jobs, and maintaining consistency between training and serving environments. The company targets high-performance ML applications including fraud detection, credit decisioning, personalization, and real-time recommendation systems where feature latency directly impacts user experience and model effectiveness. Chalk's Python-native interface dramatically reduces the friction of building and maintaining real-time ML features compared to custom Flink or Spark streaming infrastructure. The company differentiates from Tecton and Feast through its emphasis on developer experience and the simplicity of its Python feature definition syntax that requires no distributed systems expertise to use.
Global network platform securing 20% of internet traffic; $1.6B revenue growing 28%, expanding into AI inference infrastructure at 300+ edge locations.
Cloudflare is a global cloud platform providing web performance, security, and network services to millions of websites and applications worldwide. Founded in 2009 by Matthew Prince and Michelle Zatlyn and headquartered in San Francisco, Cloudflare started as a DDoS protection and CDN service and has evolved into one of the most comprehensive network infrastructure platforms, serving as the connectivity layer for nearly 20% of all internet traffic. The company went public in September 2019 at a valuation around $4.5 billion.
