Pull Reminders
Abi Noda, a 27-year-old developer from Chicago, had spent a decade working full-time jobs while building side projects. When he left his job in December 2018, he had a specific problem in mind: the inefficiency of code reviews dragging on and developers getting fatigued from repeated reminders. As an engineering manager, Abi had spent significant time manually monitoring pull requests and pinging team members on Slack. He wasn't sure if this was just his company's problem, so he validated the idea by asking peers in the "Chicago CTO" Slack group if they experienced pull requests dragging on—many responded affirmatively. He also discovered several similar "pull request reminder" projects on GitHub, confirming the problem was widespread.
Abi built the first version of Pull Reminders in just a couple of weeks using Ruby on Rails, deliberately choosing the framework for its philosophy of enabling "small teams to do big things." When he launched at the end of January 2019, he had no monetization strategy—he planned to offer it for free as a marketing vehicle for future products. The product solved a clear pain point: teams could set up reminders in Slack channels so developers would receive direct messages about assigned code reviews, plus metrics on pull request size, code review turnaround time, and reviews completed.
Abi's initial growth came through the Slack App Directory, which provided a small trickle of organic signups. Rather than wait for customers to come to him, he emailed every early user to understand who they were and what they needed. Some early users were from large companies and were clearly taking the product seriously—they requested many changes. Abi iterated based on their feedback, and by March 1, 2019, he had convinced his first paying customers to subscribe. This breakthrough moment revealed that Pull Reminders could be a real business. He eventually added a pricing page and payment form ($10/mo, $49/mo, and $99/mo plans at roughly $2 per developer per month) rather than asking each customer individually.
The biggest growth accelerant came in April 2019 when Pull Reminders was published in the GitHub Marketplace, providing a significant boost in signups. By the time of this interview (February 2019, though discussing progress through early 2019), the product was being used by over 400 companies including Pivotal, Instacart, WeWork, and Trivago. Pull Reminders benefited enormously from being parasitic on GitHub and Slack—two tools developers already used daily, making adoption frictionless. However, Abi's referral program (initially offering free gourmet coffee, then Amazon gift cards, then dual incentives) gained no meaningful traction. He also built reporting features that users didn't value, learning the hard way that he should have validated designs with mockups before investing engineering time. He wasted considerable effort on a redesigned logo that ultimately wasn't necessary.
Abi remained a solo founder focused on product improvement rather than aggressive marketing, though he planned to start writing content guides for developers interested in starting businesses—aligning his audience with his customer base. He attributed much of his success to mental resilience: the ability to push through doubt, perfectionism, and the emotional rollercoaster of entrepreneurship. His biggest personal obstacles were self-doubt when signups dipped or admired customers didn't convert, and perfectionist tendencies that led him down unproductive rabbit holes. Despite these challenges, he recognized that his "disadvantages" (solo founder, dependency on GitHub and Slack) were actually major advantages that allowed autonomy and made adoption seamless.
- •Abi validated a real, widespread problem before building—he asked peers in his network and discovered existing competing projects on GitHub, proving demand before investing significant time.
- •He chose a distribution strategy (Slack App Directory, GitHub Marketplace) aligned with where his target customers already were, rather than trying to pull them to new platforms.
- •By converting early free users into paying customers through direct conversation and iteration, he proved unit economics and business viability before scaling—reducing the risk of building features nobody wanted.
- •He remained a solo founder with low overhead and complete autonomy, allowing him to ship quickly in Ruby on Rails and pursue opportunities larger teams would reject as unprofitable.
- •His persistence through emotional ups and downs—actively managing his mental health and staying positive through growth plateaus—allowed him to sustain momentum when others might have quit.
- 1.When you identify a potential startup idea, validate it in communities where your target customers congregate (e.g., industry Slack groups, forums, Reddit). Ask directly if they have the problem you're trying to solve, and research whether existing solutions already exist.
- 2.Launch an MVP quickly using a framework optimized for speed (Rails, Django, etc.) and distribute it through platforms your customers already use daily (app marketplaces, integrations with existing tools), rather than building your own marketing engine first.
- 3.Email every early user or trial signup personally to understand their context and needs. Iterate your product based on their feedback, and after showing clear value, ask them directly if they'd pay. Use their willingness to pay to refine your pricing model.
- 4.Before investing weeks in building large features or cosmetic improvements (logos, reports, etc.), validate the approach with customers through mockups, wireframes, or written descriptions. This prevents shipping features that sound good but don't solve the real problem.
- 5.Take seriously the emotional and mental health aspects of solo founding—build a support network, take breaks when you're discouraged by temporary setbacks, and focus on your product and customers rather than getting distracted by perfectionist tangents that don't move the needle.
