Summary
Nicolas Toper is a founder and systems engineer who designs compiler- and runtime-level optimizations for JVM-scale workloads, currently commercializing that work as FastJVM—a drop-in JVM replacement that accelerates Spark-style jobs to cut cloud costs. He brings 8 issued U.S. patents in automatic parallelization, branch removal, dependency/side-effect analysis and dynamic-language compilation to production-grade runtime tooling, with public experiments and production-like benchmarks informing the product. Previously he bootstrapped and scaled multiple infrastructure businesses—CritSend (SMTP relay, ~$1M ARR) and Inboxbooster (~$200K ARR)—and applied bytecode-level optimization to Android at Manycore (YC W17). Comfortable across low-level compilers, distributed systems and operational growth, he has a track record of turning advanced research into profitable, resilient services. Based in Palo Alto with an M.Sc. from CNAM, he also explores web and mapping projects on GitHub, showing a practical curiosity beyond core runtime work.
