Plexe

Plexe is an applied AI lab and platform that builds production AI agents and machine learning models into a customer's product. Rather than selling seat based software, its senior engineers are embedded with the customer's team to scope, build, evaluate and deploy an agent, then hand it over. The vendor states that the customer owns the code, models and prompts. The underlying platform is the backend its engineers build on. It includes a builder that turns a plain English problem description into a trained model, and a way to describe an agent and watch it assembled through planning, building, verifying and testing steps, with integrations such as Gmail and Slack shown in the example. Deployment can run inside the customer's own cloud so that data does not leave it, or be hosted and managed by Plexe. The vendor reports SOC 2 Type 2 audit status and Y Combinator backing. Past work described includes a recommendations engine for a travel company, supplier routing, an enrollment acceptance predictor with a talk to your data agent, and churn prediction with semantic search. It suits product and engineering teams that want a custom AI capability shipped in weeks and kept in house. Pricing is by quote. The vendor does not publish tiers, and prices each engagement after scoping the workflow, integrations and support needed. Starting points include a scoped pilot of one workflow, a full custom build and an embedded team arrangement.
