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.
Alphabet (GOOGL) cloud platform with $43.2B revenue and #3 global market share; BigQuery data analytics, Vertex AI/Gemini, and GKE competing with AWS and Azure for enterprise cloud and AI workloads.
Google Cloud is Alphabet's cloud computing platform — providing infrastructure (compute, storage, networking), managed data services (BigQuery, Cloud Spanner, Firestore), Kubernetes and container management (Google Kubernetes Engine, the origin of Kubernetes), AI/ML infrastructure (TPUs, Vertex AI, Gemini APIs), and developer tools to enterprises, startups, and developers globally. Listed under Alphabet (NASDAQ: GOOGL), Google Cloud generated $43.2 billion in revenue in fiscal year 2024 and achieved its first full year of consistent operating profitability, representing approximately 11% of Alphabet's total revenue.
