ByteAsk on the record

What they shipped

  • From its YC profile: ByteAsk is an AI coding agent built for C and C++, the code that runs trading systems, cars, chips, and operating systems. It does not stop at a diff that looks right. ByteAsk builds, debugs, and tests every change with the real toolchain until the change holds. If the compiler, the debugger, or the tests can catch it, then ByteAsk catches it too. It runs from the terminal or inside VS Code, Neovim, and Emacs, and is available fully on-prem. (source)
  • Its own site describes it as: "ByteAsk edits your repo from the terminal, then drives the sanitizers, the debugger, and your test suite before you see a diff. Built-in support for LLVM, GCC, gdb, Valgrind, CMake, and more." (source)

Who is behind it

  • Anirudha Kulkarni, Founder/CEO: Building coding agents for C and C++ - Prev. low-latency C++ at Optiver and Quantbox - built SOTA Python-to-C++ optimizing transpiler - CSE @ IIT Delhi - Founder/CEO LawSutraAI, acquired by Manupatra, India's largest legal tech firm, where it serves 100k+ lawyers - solo travelled to 12 countries (source)
  • Pratyush Saini, Founder/CTO: Pratyush is the co-founder and CTO of ByteAsk, an AI coding tool for C and C++. He studied Computer Science at IIT Delhi. He was a core engineer on NeuralDB and BOLT, ThirdAI's CPU-only search and deep learning engines, then a founding engineer at Simbian, where he co-built the AI security agent that handles over a million incidents a year.
