Built by
We are Julia and Finn, the Co-Founders of Contact Book. We answer the support email ourselves, and ship with our small team.
Contact Book is built and run from Germany. We do not sell to enterprise on the side, we do not have a sales team to escape from, and we do not call anyone who did not ask first.
Your people, kept where you can find them.
Parents, freelancers, volunteers - the people who use Contact Book describe what changed for them.
"My kid's class list, my mum's birthday list, plumbers I trust - all in one place. Nothing leaves my account."
"I keep my lead list and my friends here side by side without mixing them up. The owner-scoping is invisible but it is the whole point."
"I tried five 'CRMs for individuals'. This is the first one that does not try to sell my data to a third-party agency."
