Meet the people and companies changing the way people work

Great companies start with great people.
We partner with innovative founders to build extraordinary companies that disrupt the status quo. ​Below are some of the companies in the Slimmer AI portfolio.

Uncover

Caroline Korteweg and Ingrid van de Pol-Mensing are co-Founders and co-CEOs at Uncover. Uncover uses AI to help litigators structure, manage, and analyse the documents in their case files — freeing up their time and helping them focus on winning their case. Uncover launched in June 2022 with 3 customers.
We are so happy to have joined forces with Slimmer AI. Their level of support is tremendous and is helping us get off to a flying start.
Why we’re thrilled to co-build Uncover

Vesper

Alexander Sterk is the founder and CEO at Vesper. Vesper uses AI to eradicate the asymmetry of information on food commodity prices​. Launched in 2019, Vesper raised a €5M Seed round in August 2021 and is rapidly expanding into new markets.
I know better than to think I can do it all myself. Slimmer AI is pushing our ambition while providing practical hands-on support to me and my team. ​
Why we're excited about Vesper

Hadrian

Rogier Fischer is co-founder and CEO at Hadrian. Hadrian uses AI to power the first fully autonomous offensive security solution. Hadrian raised a €2.5M pre-Seed round in September 2021 and went live with their first 4 launching customers in November.
Slimmer AI is a hands-on, loyal and trustworthy partner, even as a second-time founder I am grateful and impressed with the value they provide.
Why we believe in Hadrian

Sentinels

Joost van Houten is the founder and CEO at Sentinels. Sentinels uses AI to fight financial crime at global payment service providers and banks​. Launched in 2020, Sentinels raised a €7M Seed round in 2021 and is growing ARR at 5x year-over-year. In April 2022 Slimmer AI exited Sentinels, selling a majority stake to Fenergo.
Building with Slimmer AI in the early stages was instrumental in breaking into this market and for our early traction.

Biller

Derek Vreeburg is co-founder and CEO at Biller. Biller uses AI for credit risk assessment to democratise B2B commerce​​. Started in May 2021, the product went live within 3 months. In January 2022 Slimmer AI exited Biller, selling a majority stake to Banking Circle.
Slimmer AI was our ‘experienced believer in us’. The speed at which we’ve built Biller is still absolutely mindboggling.
