Case Study: FINN achieves $100M ARR growth with Retool

How FINN scaled operations to reach $100M ARR in 3 years with only 300 employees

FINN, a German automotive subscription company, needed a way to scale complex operations quickly while staying lean. As the business grew to more than 20,000 cars and expanded into new markets, its teams faced manual, spreadsheet-heavy workflows for fleet management, partner communications, and identity verification. FINN turned to Retool to help build flexible internal software without adding significant engineering headcount.

Using Retool, FINN built over 100 internal apps, including tools for car operations and KYC workflows, connected to databases and partner APIs. The results were substantial: the company says it builds operations software 10x faster than from scratch, saved hundreds of engineering hours, reduced customer verification from 15 minutes to 1 minute per ticket, and saved the support team about 200 hours per month. Retool helped FINN reach $100M ARR in under 3 years with fewer than 300 employees.
