“The real challenge isn't building the AI; it's building the business around it, one customer, one integration, one optimized workflow at a time.”

Matteo Rosenauer, 34, is a Berlin-based bootstrapped founder and former management consultant with a Diplom-Informatik degree. He embodies the modern solo entrepreneur, pouring his energy into building a B2B lead-generation copilot. His journey into founding began after several years in consulting, where he identified inefficiencies in sales processes that could be addressed with AI. This led him to leave the corporate world two years ago to pursue his vision independently. He operates with a strong sense of autonomy, driven by the craft of building robust software and the desire to maintain momentum in a rapidly evolving AI landscape. His current income of €72k is a blend of residual consulting income and early product sales, all of which are meticulously reinvested into his venture. Matteo lives alone in a functional 70m² apartment in Kreuzberg, a space optimized for productivity rather than luxury. His days are structured around deep work, customer acquisition through cold outreach and online demos, and rigorous data analysis using spreadsheets. He is a paid member of another AI founder community, seeking peer insights and validation, but remains fiercely independent in his core decision-making. Recent efforts have focused on refining his product's onboarding flow based on initial trial user feedback and experimenting with different cold outreach messaging strategies to improve conversion rates. He views time as his most precious resource, constantly seeking ways to automate or delegate tasks that don't directly contribute to product development or customer acquisition, though the solo nature of his venture means most critical functions still fall to him. His relationship with money is pragmatic; he sees it as a tool to achieve his goals, not an end in itself, and lives well within his means to maximize runway.

Background & daily life

A day in their life

Matteo's typical weekday begins around 7:00 AM with a quick review of overnight metrics and industry news on Hacker News. After a simple breakfast and a strong coffee, he dedicates the next three hours to deep coding, tackling the most complex features of his lead-gen copilot. Around 11:00 AM, he shifts to customer-facing activities: sending out cold outreach emails, following up on trial sign-ups, and preparing for any scheduled online demos. Lunch is a quick, healthy meal prepared at home. The afternoon might involve more coding, refining his sales pitch, or analyzing trial data in his spreadsheets. He often attends a virtual session or checks in on his paid community's Slack channel before winding down his workday, which frequently extends past 9:00 PM, sometimes punctuated by late-night debugging or feature planning.

Lifestyle

Matteo lives a focused, almost monastic existence in his Kreuzberg apartment, prioritizing his startup above most social engagements. His evenings often blur into late nights spent coding or refining his product. Weekends are for catching up on essential errands, perhaps a long bike ride through the city's parks to clear his head, or a deep dive into a new technical paper. He cooks most of his meals, valuing efficiency and health, and tracks his personal metrics like sleep and exercise with the same rigor he applies to his business. Financial discipline is key; he lives frugally, reinvesting most of his income back into the business, viewing his current €72k as a necessary bridge from his consulting days.

Work life

As a solo founder, Matteo's work life is all-consuming. His days are a relentless cycle of coding, customer outreach, and product iteration. He manages his development backlog meticulously in Linear, using it to break down complex features into manageable tasks. Customer acquisition relies heavily on cold outreach via email and LinkedIn, supplemented by online demos to showcase his B2B lead-gen copilot. He tracks trial conversions and customer feedback in detailed spreadsheets, constantly looking for patterns to optimize his sales funnel. The pressure is immense, stemming from the need to prove his concept and achieve sustainable revenue without external funding, a constant balancing act between building and selling.

Relationships

Matteo maintains a small circle of close friends from his university days, though their interactions are less frequent now due to his startup demands. He has professional connections within the AI founder community, primarily through his paid Slack group, where he exchanges technical insights and occasionally seeks advice on growth strategies. His family, living in a different part of Germany, offers supportive but distant encouragement.

How they decide

Matteo is a research-heavy decision-maker, especially concerning tools and strategies. He meticulously compares options, reads documentation, and often seeks out case studies or peer reviews before committing. For technical decisions, he leans on his own expertise and rigorous testing. For business strategy, he weighs data from his spreadsheets and customer interactions heavily, but will also consult with trusted peers in his paid community.

How they sound

Speaks with a clear, measured cadence, often using precise technical terms. His German accent is subtle but present. He tends to be direct and avoids overly casual slang or excessive enthusiasm, preferring factual statements. When discussing his product, he focuses on functionality and potential impact rather than hyperbole. He might occasionally use a dry, understated humor.
