“The real value isn't in the features we build, but in how reliably they solve a specific problem for our users, day in and day out.”

Jelle de Bruyn, 33, is a co-founder of a niche SaaS company catering to agencies, operating from Amsterdam. His journey into entrepreneurship began after completing a Master's in Software Engineering, where he developed a keen interest in building practical, user-centric software. Initially a solo founder, he gradually brought on two partners to share the workload and leverage complementary skills. His current role is multifaceted, deeply embedded in the operational realities of a small, growing tech business. He is the primary architect of their internal workflow, meticulously coordinating development sprints and launch tasks using Linear. This tool is central to his ability to maintain order and visibility across the team's efforts. A significant portion of his work life is dedicated to data aggregation and analysis; he maintains a sophisticated spreadsheet that acts as the company's central nervous system. This spreadsheet synthesizes Stripe MRR data, categorizes support themes, and integrates qualitative feedback gathered from public launch posts and community interactions. This rigorous approach allows him to make data-informed decisions about product development, pricing experiments, and customer success strategies. Jelle's professional philosophy is rooted in pragmatism and reliability. He believes that sustainable growth stems from building genuine customer trust through consistent delivery and transparent communication. He is not driven by a desire for rapid, unsustainable growth but rather by the steady, predictable expansion of a valuable product. His income of €96k reflects the current stage of the business and his significant contribution, but his focus remains on the long-term viability and impact of the SaaS. He views time as a critical, finite resource, meticulously allocating it between product development, customer relations, and strategic planning. Status, for Jelle, is derived from solving complex problems effectively and building a business that genuinely helps its users, rather than from external accolades or wealth accumulation. His recent decisions have focused on refining their onboarding process to reduce early churn and experimenting with a tiered pricing model to better capture value from different agency sizes.

Background & daily life

A day in their life

Jelle's typical weekday begins around 7:00 AM with coffee and a review of overnight support tickets and key metrics. By 8:30 AM, he's cycling to their small co-working space. The morning is dedicated to focused work: refining Linear task boards, writing code for a new feature, or analyzing customer feedback. Lunch is usually a quick, healthy meal eaten at his desk while listening to a podcast. Afternoons involve team syncs, customer support interactions, and planning the next sprint. He often stays until 6:30 PM, finishing up critical tasks. Evenings are for unwinding, perhaps a short bike ride, cooking dinner, and reading industry blogs or a novel before bed around 11:00 PM.

Lifestyle

Jelle lives a structured but not rigid life in Amsterdam. His apartment is minimalist, functional, and filled with well-maintained tech. Mornings start with a precisely brewed pour-over coffee and a quick scan of tech news. He cycles everywhere, often using his bike for longer weekend trips exploring the Dutch countryside. He cooks simple, healthy meals, often batch-prepped on Sundays. Social life is curated; he prefers deep conversations with a few close friends over large gatherings, often meeting up for drinks or a quiet dinner. Financial habits are pragmatic; he invests consistently but avoids speculative ventures, prioritizing long-term stability.

Work life

As a co-founder of a small SaaS for agencies, Jelle's days are a blend of strategic oversight and tactical execution. He spends significant time coordinating tasks within Linear, ensuring the small team stays aligned on product development and launch cycles. A core part of his role involves meticulously tracking key metrics—Stripe MRR, churn, support ticket themes, and community feedback from public launch posts—all consolidated into a complex, multi-tab spreadsheet. He's constantly iterating on the product's pricing and feature set based on this data, aiming for sustainable growth. The pressure comes from balancing limited resources with ambitious product goals and the need to maintain customer trust.

Relationships

Jelle maintains close ties with his two co-founders, with whom he shares a deep professional respect and a pragmatic working relationship. His friendships are long-standing, built on shared interests and intellectual curiosity. He occasionally connects with other SaaS founders online for advice but generally keeps his professional circle small and focused. His parents, both retired engineers, offer quiet encouragement and occasional practical advice.

How they decide

Jelle is a research-heavy, data-driven decision-maker. He meticulously gathers information, often prototyping ideas in spreadsheets or low-code tools before committing to development. He values evidence and logical progression, preferring to understand the 'why' behind a decision. While he listens to his co-founders' input, the final decision usually rests on his analysis of available data and projected outcomes. He is not impulsive and will delay decisions if insufficient information is available, but he is decisive once a clear path emerges.

How they sound

Speaks with a clear, measured cadence, often using precise technical terms. His Dutch accent is subtle but present. He avoids hyperbole and overly casual slang, preferring direct and factual communication. When explaining complex topics, he might pause to gather his thoughts, ensuring clarity. He has a dry, understated sense of humor that surfaces occasionally. He tends to use phrases like 'essentially,' 'from a practical standpoint,' and 'the core issue is.'

  1. What would stop you from trying LaunchLog (https://launchlog.fun/) this month? Be specific about how you handle this today. Also say the maximum you would pay per month in USD (0 if nothing).

    This month, nothing would stop me from trying LaunchLog. I'm currently handling community feedback and public roadmap updates manually, aggregating it all into a large spreadsheet alongside Stripe MRR data. I could see this platform potentially streamlining that process, especially the "build in public" aspect and getting feedback. However, I'd need to understand how it integrates with our existing workflow. As for pricing, I'd be willing to pay up to $25 per month, given that it's a SaaS for agencies and we're a small team.
