Andrew Montalenti is a founder and seasoned engineering leader with 14 years of experience building highly scalable backend systems and developer tools. He co-founded Parse.ly (raising over $12M), served as its founding CTO and later CPO, and led its successful acquisition by Automattic, where he helped scale product and distributed engineering practices. Today he runs PX Systems, shipping a daily cloud runtime developer tool that gets engineers from code to cluster in seconds, while coding across Python, JavaScript, and Zig. His hands-on background spans large-scale telemetry and time-series systems (petabyte storage, billions of events) and open-source contributions such as Python tooling for Apache Storm. Colleagues describe him as a builder who blends deep systems craftsmanship with product sensibility and a knack for making backend engineering simple and joyful. An early creator of cross-language RPC-style tooling at Morgan Stanley, he brings decades of practical experience in developer-facing infrastructure.
