About this list
Generative work at startup scale usually means one of two things: a feature that reads documents and returns structure, or a feature that writes something a user sees. This page is much stronger on the first. Dashbouquet publishes the clearest model-selection record here, evaluating Llama 3, Mixtral, GPT-4 and VILA for BetterYou's therapist dashboard, alongside an extraction platform pulling menus from 10,000-plus venues in 12 languages at 100 GB a day. Yield Studio's Greensight module reads ESG documents and fills questionnaires inside Greenscope's platform, cutting report editing to under 30 minutes. Modulai brings the deepest production machine-learning bench on the page, and Lizard Global's generative exposure sits at the application layer around models the client already licenses.
Read the evidence lines before shortlisting, because two things get conflated here constantly. A documented model bake-off proves a team can choose; a published usage or accuracy figure proves the choice survived contact with users, and several of the generative engagements on this page publish the former without the latter. Imobisoft's documented delivery is risk scoring and compliance reporting rather than content generation, which is worth knowing before the first call. Ask each candidate for a generative feature in front of users today, and what it does when the model returns something wrong.
Expert Insight
Why startup fit matters for Generative AI
Startup budgets buy scoped builds, not programs—the agencies here document work shipped in weeks to months, priced for companies that measure runway.
At small agencies the case-study authors are the delivery team, which removes the seniority lottery that makes large firms risky for small engagements.
Code ownership decides whether the engagement was an asset or a dependency: every documented build here describes a system the client runs, and that question belongs in your first call.
