A small company on purpose
Destello AI Incorporated sells fixed-scope AI engineering to US businesses. The founder does the work himself, so there is no handoff between the person who scopes your project and the person who builds it.
What we do
We fix, build and verify systems built on large language models: assistants that cite their sources, migrations off retiring models, document extraction, cost reduction, evaluation harnesses and automation. Each engagement has a written scope, a published price and a paid first step that is credited to the build.
We also build our own AI tools, including the open-source UnvibeCode.
Destello is Spanish for a flash or glint of light: the moment you can see clearly what a system is doing.
Suresh Rajendran

He builds production systems that give reliable results to large numbers of non-expert users, in real time, at a unit cost low enough to sell. He is first author of a peer-reviewed 2026 paper in applied finance and reviews manuscripts in applied AI for Elsevier and Springer Nature journals.
