Engineering assets, sold outright, to teams who own their own stack.
Vlaander LTD designs and sells deterministic source code in C++ to enterprise procurement desks, defense integrators, and quantitative research groups. Nine assets in the catalog. Each one is formally specified, fuzzed, sanitizer-clean, and shipped as a signed source tarball you own forever — with the independent security review published per asset as it lands.
We sell to anyone who wants to build with what we wrote. The advantage is not the code — it is the team that ships it first, integrates it best, and operates it cleanest. We provide the starting line. Survival of the fittest.
