Company Summary We're a product studio and tech lab that embeds with startups and growth-stage companies to turn early traction into scalable systems. Our model combines product, engineering, and AI as a unified solution led by a team of former Amazon and Google leaders with deep experience building at scale, fast. We work through a product-led model that aligns strategy, data, and delivery across three core capabilities: - Full Stack Analyst (FSA) - Analytics-as-a-service with insights, automation, and reporting full-time data team is needed. - Data Maturity Journey - From raw events to AI-readiness, we help teams unify their data, define key metrics, and build ML-ready infrastructure. - Z21 Pods - Embedded cross-functional pods that build and scale products fast, with tight iteration loops and full end-to-end ownership. We also developed the minimum scale velocity (MSV) framework, our proprietary system for helping startups scale without overbuilding, overhiring, or burning out. MSV defines the smallest viable momentum a business needs to grow, intentionally bridging the gap between PMF and real scale.
