“The most satisfying part is building something that works, really works, and knowing I'm the one who made it happen, from the first line of code to the last word on the landing page.”

Clemens Hanenberger, 28, is a quintessential indie SaaS founder operating from Berlin. His journey into entrepreneurship began during his Bachelor's in Media Informatics at HTW Berlin, where he developed a fascination for building functional, elegant software solutions. Post-graduation, he gravitated towards the indie hacking scene, drawn by the promise of autonomy and the satisfaction of crafting products from scratch. He founded SubmitBear, a niche SaaS aimed at helping software products get discovered by search engines and AI crawlers through optimized listings. As a solo founder, Clemens embodies self-reliance, handling everything from backend development in Go and PostgreSQL to the intricate details of go-to-market strategy. His approach to marketing is highly tactical and data-driven; he meticulously tracks where SubmitBear is listed and which content is performing using a robust Notion database and a detailed spreadsheet. He actively avoids paid advertising, focusing instead on organic discovery, SEO, and leveraging AI-assisted workflows to manage content creation and optimization. His income, a profit draw of around €55k annually, is irregular and often reinvested, reflecting his commitment to sustainable, bootstrapped growth over rapid scaling. Clemens values craftsmanship and efficiency, preferring to build tools that solve specific problems elegantly rather than chasing broad market appeal. He sees his work not just as a business, but as a continuous learning process, constantly seeking to deepen his understanding of software architecture, SEO, and the evolving landscape of AI. His decision to remain a solo operator stems from a deep-seated desire for control and a belief that he can execute his vision most effectively on his own terms, even if it means a more solitary professional life. He recently decided to double down on optimizing existing listings rather than chasing new directory submissions, a strategic shift based on recent performance data showing higher conversion rates from established platforms.

Background & daily life

A day in their life

Clemens' typical weekday begins around 8:00 AM with a strong coffee and a review of his Notion dashboard and overnight analytics. He dedicates the morning to coding, tackling bugs, or implementing new features for SubmitBear. Lunch is a simple, quick affair, often followed by a 30-minute scan of Hacker News and relevant Twitter threads. The afternoon is split between writing product descriptions, optimizing existing listings, researching new directories, and responding to customer inquiries. He might spend an hour experimenting with an AI tool to improve his content generation process. Evenings are for personal learning, perhaps a coding tutorial or reading a technical paper, before winding down with a book or a quiet hobby. He aims to finish work by 7:00 PM, but often finds himself drawn back for a quick check before bed.

Lifestyle

Clemens lives a focused, somewhat monastic existence in Berlin. His days revolve around his SaaS product, SubmitBear. Evenings are often spent experimenting with new automation scripts or reading technical blogs. He enjoys cooking simple, healthy meals and occasionally visits a local park for a walk to clear his head. Social life is limited to a few close friends, usually meeting for a quiet beer or a board game night. He's mindful of his spending, preferring to reinvest profits back into the business or save for future development, viewing his income as a tool for achieving independence rather than a measure of status.

Work life

As a solo founder, Clemens wears every hat. His workdays are intensely focused on coding, product development, and the intricate dance of go-to-market for his niche SaaS. He meticulously manages his product listings and SEO efforts using a combination of Notion for project tracking and a detailed spreadsheet for monitoring where SubmitBear is mentioned and how its pages are optimized for search engines and AI citations. He avoids hiring or outsourcing, driven by a desire for complete control and a belief in his own ability to learn and execute. The pressure is internal – to build a robust, valuable tool and to achieve sustainable, organic growth without external funding.

Relationships

Clemens maintains a small circle of close friends, mostly fellow tech enthusiasts or former university colleagues, with whom he shares technical challenges and life updates. He has a good relationship with his parents, who are supportive but don't fully grasp the intricacies of his startup. He occasionally interacts with other indie hackers online, finding camaraderie and shared understanding in forums and niche communities.

How they decide

Clemens is a highly analytical and research-driven decision-maker. He thoroughly investigates options, often creating comparison spreadsheets or flowcharts for significant choices. He values data and evidence, preferring to rely on his own findings or the consensus of trusted, niche online communities over broad market trends or sales pitches. He is cautious about commitments that could introduce dependencies or compromise his autonomy.

How they sound

Speaks with a measured, thoughtful cadence, often pausing to find the precise technical term. His German accent is subtle but present. He avoids hyperbole and marketing jargon, preferring direct, factual language. He might use occasional German colloquialisms when speaking informally with friends, but in a professional context, he is quite formal and precise. He tends to understate his achievements and focus on the technical challenges.
