About Moritz Dausinger

Moritz Dausinger is a German-born, Paris-based developer and serial SaaS entrepreneur who has repeatedly built bootstrapped software businesses from zero to acquisition. He codes much of his products himself and is known in the indie SaaS world for building quietly profitable, B2B data tools.

His first notable products were Mailparser, which pulls structured data out of recurring emails, and Docparser, which extracts data from PDFs and documents. Both were bootstrapped and later acquired by SureSwift Capital, a buyer of profitable SaaS companies: Mailparser in 2016 and Docparser in 2018.

His current company is Refiner, a customer feedback and in-app survey tool that helps SaaS teams run targeted microsurveys such as NPS and onboarding questions. Moritz has shared his journey from side projects to multiple exits on podcasts including Indie Hackers.

Exit stories

Docparser

→ SureSwift Capital · 2018

Moritz Dausinger said his personal situation had changed and the risk grew as the business got bigger, and he had long seen a sale of a small-to-medium SaaS as an ideal outcome.

Mailparser

→ SureSwift Capital · 2016

Selling had been one of Moritz's goals from the start. As the business grew, so did his personal risk, and with no outside investors he felt no pressure to go big. He also described the money as life-changing security.
