Slimmer AI

Slimmer AI (also styled Slimmer.ai) is a Groningen-based AI startup studio that builds B2B software-as-a-service ventures combining AI research with product development. Jan_Wilmake worked there as a senior contract developer from May to July 2024, embedded in the ClaimWise venture.

Model

Slimmer AI operates as an internal startup accelerator: it finds or generates venture concepts, assembles engineering teams around them, and builds early-stage SaaS products. As the company puts it: "Slimmer doesn't build for you, but with you." Engineering staff rotate across ventures rather than being permanently assigned to one product.

The company is backed by institutional investors including NOM (Noordelijke OntwikkelingsMaatschappij), the regional Northern Netherlands development fund.

ClaimWise

During Wilmake's engagement, Slimmer AI's primary active venture was ClaimWise — an AI-powered patent search and claim construction platform targeting US patent attorneys and IP managers handling approximately 100 patent applications per year.

Technical Stack

ClaimWise ran on AWS using a microservices architecture:

Application code was written in Python (backend) with Lambda Powertools (FastAPI-compatible) and React (frontend).

Wilmake's Work

Wilmake's work included ML model deployment UI, frontend and backend feature tickets, data migration pipelines, and claim construction interface improvements.

Mika

A second Slimmer AI venture active during the same period was Mika — an AI-powered tax and accounting advisory tool targeting small German businesses (under 50 employees). Mika aimed to reduce the cost of tax advisor hours by 80% using bank account integration, receipt upload, email invoice parsing, and Slack-based input.
