Claude Ritter: “At Lieferheld, it was just a crazy couple of years in the beginning. I literally did not go home for like 10 days in a row. I just went to H&M and bought some new t-shirts and boxers and was just changing clothes like that. We were just working all the time. And I believe it was fairly similar at Lieferando. Both teams had sort of an insane level of wanting-to-win and competitiveness. And, obviously the competition between the two teams further fostered and accelerated the success.”

From Founding in China Twice to Starting Lieferheld and BOOK A TIGER

Claude Ritter is one of Germany’s online entrepreneurs who can be labelled as to have been quite successful in his career so far. He co-founded online food delivery service Lieferheld in 2010, which was later sold to the widely known Delivery Hero Group. After the acquisition, Claude served as CPO and was in charge of global product and engineering at Delivery Hero. Law suits, police raids and almost getting into fist fights with his rivals at other Berlin-based food delivery startups were part of the experience of digitalizing the food delivery market in the early 2010’s – having him go through extremely tough times and fierce competition while trying to make it as a founder. Prior to his work in the online food delivery market, he had been active as entrepreneur before though – he started Aionics (a Swiss-based web agency) and co-founded two companies (The NetCircle, DUQI) in China where he lived for 5 years.

In 2014, Claude started his latest venture: As co-founder & CPO of Book A Tiger, he is now working on digitalizing the cleaning service market. Again being in a competitive situation with another Berlin-based startup (Helpling), BOOK A TIGER offers a modern alternative to traditional cleaning services. With its online platform, it makes household cleaning accessible and affordable to everybody. The startup connects customers with reliable cleaners. Like this, BOOK A TIGER is reducing illicit work within the industry and is giving its client the benefit of having more available free time.

In this regard, the company did an interesting pivot in 2016: A first only connecting its clients with freelance cleaners, BOOK A TIGER started to employ its cleaners directly and to focus more on its B2B activities. This turned out to be a smart decision leading to some impressive success: The startup raised a double-digit financing round in early 2017 (by now 20m€ have been invested into BOOK A TIGER) and the B2B business grew by 1,600% from starting the pivot to the point of the financing round. The customer retention rate improved by the factor of 2,5x. About 1,000 employees work for the startup by now.

Besides his main work on BOOK A TIGER, Claude is also a Partner at Cavalry Ventures, a Berlin based (pre-)seed fund, and invests into early-stage startups as a business angel.

Claude Ritter on Startup Notes

In this episode, we discuss Claude’s journey and his learnings as an entrepreneur so far, how to start a startup and his work on Book A Tiger. During our very insightful conversation, Claude gives advice for aspiring founders, answers some of our listeners’ questions, talks about mistakes and also describes his criteria for investing into early-stage startups as a business angel.

Out of the many points discussed with Claude in this regard, there are a few that stand out. Besides the exciting ‘behind the scenes’ stories that he shared with us about the intense competition between Lieferheld and Lieferando from the early 2010’s, he explained in detail what matters to him when considering an investment into a startup as a business angel/VC. According to Claude, the assessment of an investment opportunity especially comes down to the personal fit between founders and investors. As he states in our conversation, in this regard also the little things matter – like being on time for a coffee meeting or pitch and being attentive and not replying to emails while in a discussion. But of course any investment opportunity must also be backed up by a business idea that makes sense. As he explains, this could either be by a company solving a specific problem that people have or by developing a technology that is simply ‘amazing’. The best way to get in touch with Claude for pitching a startup is definitely via personal introduction. As he describes in our episode, he e.g. does not accept any invitations on LinkedIn by people that he does not know or has not gotten an intro to.
