About
Hi, I’m Lennart. I’m a Business Economics master’s student with a background in entrepreneurship and e-commerce.
During my bachelor’s degree in Business Administration, I founded and built “Mein Malen nach Zahlen,” a D2C e-commerce brand selling paint-by-numbers kits and personalized sets made from customers’ own photos. I grew it to six-figure annual revenue while managing paid acquisition, conversion optimization, supplier management and day-to-day operations.
Alongside my master’s degree, I work in AI Consulting & Business Development at Lucid Labs, a Berlin AI studio building productive AI agents for mid-sized companies.
Outside of work and university, you can usually find me kitesurfing, playing table tennis, hanging out with friends or heading outdoors for my next adventure in nature.
