About ByteAsk
Summary
ByteAsk builds an AI coding agent purpose-built for C and C++, the languages at the core of trading systems, automotive software, chip firmware, and operating systems. Rather than generating a plausible-looking diff and stopping, it runs the actual compiler, sanitizers, debugger, and test suite against every change until the output is verified clean. Engineers replace the manual cycle of writing code, building, running tests, and triaging failures by hand.
Business model
Paid plans at tiers shown on the pricing page, with a free entry point.
Go-to-market
Individual C and C++ developers adopt it through a one-line terminal install on Linux or macOS, with editor integrations for VS Code, Neovim, and Emacs, and a fully on-premises deployment option for teams with strict data requirements.

The AI coding agent for C and C++
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.

Score every batch against your own thesis
GPAgent's sourcing agent reads every company in a batch, scores each one against your fund's thesis in a private workspace, and lines up the founders worth meeting before Demo Day. You decide who to contact. Your scores, notes, and pipeline never appear on these pages.
