About
Customer.io is a marketing automation and customer messaging platform founded to give product-led businesses precise, behavior-driven control over how they communicate with users across email, SMS, push notifications, and in-app messages. The company was built on the philosophy that the most effective marketing messages are triggered by what users actually do — not by static lists or scheduled blasts — and that every growth and lifecycle marketing team deserves tools as powerful as those used by engineering teams. Customer.io targets product-led SaaS companies, e-commerce businesses, and subscription platforms where user behavior data is rich and timely communication drives retention.\n\nCustomer.io's platform allows marketers to build sophisticated behavioral trigger campaigns using event data streamed from their applications, segment users by real-time attribute combinations, run A/B tests on message content and timing, and analyze campaign performance through cohort-level revenue attribution. The platform is designed to be developer-friendly while remaining accessible to non-technical marketers, with a robust API layer alongside a visual campaign builder. Its 117% net revenue retention rate — meaning existing customers expand their spending by 17% annually on average — reflects deep product stickiness and growing platform adoption within its customer base.\n\nCustomer.io crossed $100 million in ARR in September 2025, representing 37% year-over-year growth, on a total funding base of less than $40 million — a capital efficiency ratio exceptional by any SaaS benchmark. With 439 employees, the company generates significantly more revenue per employee than most comparable SaaS businesses. Customer.io competes with Braze, Iterable, and HubSpot but differentiates through superior behavioral event handling, API-first architecture, and its lean, profitable growth model that has made it a widely cited example of capital-efficient software scaling.

About
Ankr is a Web3 infrastructure platform offering remote procedure call node access to more than 30 blockchain networks through a globally distributed network of nodes run by independent operators.

Its public free-tier RPC endpoints — available for Ethereum, BNB Chain, Polygon, Avalanche, Fantom, and dozens of others — have made Ankr one of the most widely used infrastructure providers in the multi-chain developer ecosystem.
