A letter from the founder

Dear Founders,

We built Switzerland’s most used legal AI platform, trusted by over 8’000 legal professionals. When we were building Foundersign, we faced the same legal challenges many of you know well. We needed LOIs, SaaS contracts, employment agreements, terms & conditions, DPAs, and many other legal documents.

Doing this ourselves was time-consuming and uncertain. Asking lawyers to handle everything is secure, but too expensive and slow.

Today we are using Foundersign ourselves for our own legal matters. We want to make this advantage available to startups as well: we take care of your legal matters. You focus on building the next generation of great startups.

Warm regards,

Marco Henri, signed
