Claudiu Murariu, InnerTrends
Signs You Chose the Wrong SaaS Co-Founder
Claudiu Murariu is the founder and CEO of InnerTrends, a growth analytics platform for SaaS and web products. InnerTrends uses data science to help companies understand their user onboarding process and convert more first-time users into customers. The company was founded in 2015 and is based in Romania. Before InnerTrends, Claudiu built PadiCode, a behavioral targeting product that reached $300K in annual revenue with just three employees. The company attracted major clients including Adidas, Reebok, and Vodafone, largely through clever integration partnerships with email platforms like Campaign Monitor and AWeber. But a SaaS co-founder conflict nearly destroyed everything. Claudiu and his partner had fundamentally different visions for the business - he wanted to grow it, while his partner wanted to build something she could exit from without being needed. They avoided the hard conversations until the conflict exploded, and Claudiu left as a passive shareholder. When he started InnerTrends, Claudiu made two deliberate changes based on the SaaS co-founder lessons he had learned. First, he brought on investors to serve as external mediators who could catch problems early. Second, he chose co-founders based on skills they had now, not skills they might develop later. The product journey was equally instructive. InnerTrends started by trying to answer any analytics question, but user testing revealed nobody could even formulate a question. After scrapping months of work, Claudiu narrowed the focus to user onboarding - solving one problem deeply rather than many problems superficially. That pivot led to 10 paying customers within months of the public launch.
