Welcome Home, West Coast

A hundred people, one new headquarters, and a lot of competitive mahjong. Chalk's San Francisco office is officially open.

Chalk celebrated the opening of its new San Francisco headquarters with 100+ engineers and builders from the Bay Area AI and ML infrastructure community.

Chalk's Spring Fling: Where to Find Us This Season

We're celebrating our new office — and the timing couldn't be better. We've got a packed spring ahead, from Snowflake Summit to AI Council and more.

Chalk's Spring Fling is its most ambitious events season yet. From an SF office warming party to Bronze sponsorship at AI Council, a first-time presence at Snowflake Summit (booth #2611, June 1–4), and something in the works at Databricks Data & AI Summit, Chalk is showing up everywhere AI and data infrastructure is being built.

Feature Store Freshness 

Most feature stores are built around batch pipelines and materialized storage, which creates an inherent freshness ceiling. Tightening staleness settings cannot overcome architectural limits. This article explains why traditional feature stores struggle with real-time freshness and how a compute-first approach enables on-demand feature computation, lower latency, and improved correctness for time-sensitive ML use cases like fraud detection and underwriting.
