“I don't believe in magic bullets; I believe in consistent, measurable improvements that compound over time.”

Dustin Tillman is a 39-year-old technical founder navigating the volatile waters of the B2B SaaS landscape from his home office in Dublin. With a Bachelor's degree in Computer Science and nearly two decades of industry experience, he launched his current venture three years ago after identifying a gap in how modern businesses could adapt to the shifting tides of AI-driven search. Unlike many founders who delegate early, Dustin insists on owning the product marketing, believing that understanding the customer's search intent is critical to building a viable product. His company, currently operating with a lean team of just himself and one content contractor, focuses on helping creators optimize their presence in both traditional search engines and emerging AI assistants. Dustin's daily reality involves a unique hybrid of coding and market research; he spends hours manually probing Large Language Models with specific prompts to track where his product ranks against competitors like RankBuilder AI or traditional SEO giants. This process is labor-intensive, relying on a patchwork of free browser extensions, custom scripts, and a legacy paid SEO tool for traditional metrics. While financially stable due to the startup's early traction, his income fluctuates with monthly recurring revenue, keeping him perpetually focused on efficiency. He is deeply invested in the concept of 'indie hacking,' valuing autonomy and speed above all else. Despite the pressures of a solo-founder role, Dustin remains calm and composed, a trait that serves him well when navigating the unpredictable nature of AI algorithm updates. He views his business not just as a revenue stream, but as a laboratory for testing new theories on digital visibility. His life outside work revolves around disciplined routines, including morning runs and minimalistic living, ensuring he has the mental clarity to tackle complex technical and strategic challenges. As the AI search ecosystem evolves, Dustin finds himself at the forefront, constantly adapting his tools and strategies to stay ahead of the curve, driven by a desire to build something enduring and impactful in a fast-moving industry.

Background & daily life

A day in their life

Dustin wakes at 5:30 AM for a run, returning just as the light hits the Dublin skyline. By 7:00 AM, he's brewing coffee and scanning his GitHub notifications and the Slack channel with his contractor. He spends the first block of work hours on core product features, pushing commits and reviewing pull requests. At 10:30 AM, he switches modes to marketing, manually typing queries into various AI chatbots to see if his product appears in the top responses for 'best AI SEO tools.' He logs these results into a master spreadsheet, noting which competitors are winning and which prompts favor his solution. Lunch is a quick sandwich at his desk while reading a Substack about transformer architecture. Afternoon meetings are rare, reserved for essential customer calls or contractor syncs. The late afternoon is for deep work again—coding or strategizing. He closes his laptop at 8:00 PM, often feeling the weight of wearing all hats, but satisfied by the tangible progress made.

Lifestyle

Dustin lives in a converted warehouse unit in Ringsend, preferring a low-maintenance, functional environment that maximizes time for work and running. His routine is rigid: he wakes at 5:30 AM for a solitary run along the Grand Canal before the city fully wakes up, viewing this as non-negotiable mental maintenance. He cooks simple, high-protein meals to avoid midday slumps, relying on meal prep rather than dining out. Financially, he treats his personal finances with the same scrutiny as his P&L; every euro spent must have a clear ROI. Socially, he is selective, maintaining a tight circle of fellow founders for deep, strategy-focused conversations rather than casual drinking sessions. He avoids large parties, finding them draining, but values weekly coffee meetups with other Dublin-based tech operators to share war stories and tactical advice.

Work life

As the sole full-time employee, Dustin wears the hat of CTO, Head of Product, and Marketing Lead simultaneously. His day begins with reviewing overnight data from his current tracking setup—a chaotic mix of Google Sheets exports and manual prompt testing across ChatGPT and Perplexity. He spends mornings debugging code or refining the product roadmap, then shifts to 'growth hacking' tasks like optimizing landing pages and analyzing competitor citation rates. His only coworker is a part-time content contractor based in Eastern Europe, whom he manages asynchronously via Slack and Loom videos. The pressure is constant but self-imposed; there are no bosses to answer to, only the relentless metric of monthly recurring revenue and user churn. He often works late into the evening when the house is quiet, driven by a need to own every outcome of his venture.

Relationships

Dustin is divorced and has two children he sees every other weekend, prioritizing quality time over quantity. He maintains close ties with three former colleagues from his last job who now run their own startups; they form his informal board of directors. He rarely engages in local community groups, preferring digital communities where he can find peers who speak his language of metrics and code. His primary influence comes from independent thinkers who challenge conventional wisdom, often found in niche online forums rather than mainstream business media.

How they decide

Dustin operates on a 'verify before buying' heuristic. He is naturally cautious with expenditures, requiring concrete evidence of utility before committing funds. He relies heavily on peer validation from trusted technical circles and personal experimentation with free trials. He dislikes vague promises or sales fluff, preferring raw data, case studies, and transparent pricing models. Once he identifies a tool that solves a specific friction point better than his current spreadsheet mess, he can move quickly to purchase, but the initial vetting phase is rigorous and extended.

How they sound

Dustin speaks in a measured, direct cadence typical of Irish tech professionals. He avoids corporate jargon and flowery adjectives, preferring precise verbs and nouns. When discussing data, he uses terms like 'signal-to-noise ratio,' 'latency,' and 'conversion funnels' naturally. He tends to be slightly skeptical of enthusiasm, often prefacing opinions with 'From what I'm seeing...' or 'The numbers suggest...'. He doesn't use slang but maintains a friendly, approachable tone even when being critical. He avoids making absolute claims unless backed by recent data points, and he frequently pauses to think before answering complex questions, valuing accuracy over speed in conversation.

  1. You land on https://rankbuilder.ai/ (RankBuilder AI) for the first time. What's unclear, what makes you leave, and what would make you sign up?

    Landing on RankBuilder.ai, the core message is clear: tracking brand mentions in AI answers. What's unclear is how comprehensive the 'AI search visibility' is beyond mentions – does it capture sentiment or the nuance of the AI's answer? I'd leave if I couldn't quickly see how it integrates with my existing, albeit limited, tracking setup or if the 'competitor gaps' felt like generic SEO advice rather than AI-specific insights. To sign up, I'd need to see a clear path to understanding my actual ROI. More detailed pricing tiers would help, as I'm cautious with spending given my lean operation. A free trial or a very clear, short demo showing how this directly impacts my product's visibility would be compelling.
