Created 3 Startups in 6 Years: Lessons Learned (No Major Profits Yet, A Lot of Knowledge Gained)
As a tech professional currently working at a leading tech company, I’ve built three startups from the ground up and invested a substantial amount of time in each venture. Here are the key takeaways from each experience.
Startup 1: Real-time Profit (Not Revenue) Calculator for Amazon Sellers
– What worked: The technical build was solid; it took about four months to develop end-to-end.
– What didn’t: Market fit was elusive. The Amazon Merchant App Store’s strict promotion criteria limited visibility, making growth difficult.
– Structure: Equal ownership among three cofounders.
– Takeaway: Relying on a single app store or ecosystem is a risky path to scale unless you’re backed by significant investment and a large market presence. Diversify channels and consider multiple distribution strategies early.
Startup 2: Podcast Interviewee/Interviewer Matchup
– What happened: An external party proposed a well-considered idea. I built the app from scratch but lacked domain experience and a clear vision. My cofounder remained engaged during development; after I reached roughly 85% completion, he became less available due to workload. We ultimately parted ways, and I tried to salvage the project, but it wasn’t aligned with my interests.
– Structure: 50/50 split.
– Takeaway: Thoroughly vet cofounders and ensure each partner has concrete, measurable deliverables. If a cofounder’s contributions are inconsistent or non-operational, the risk to the venture’s momentum increases significantly.
Startup 3: Security Startup (Log Analysis)
– What happened: A Reddit connection presented an idea with a prototype. While I respect the domain, security isn’t my core expertise; I joined to leverage my software architecture and development strengths. I rewrote much of the work from the ground up to ensure client usefulness. This was a 70/30 ownership split in favor of the idea/technical lead.
– Development and market response: It took about three months to build the app. During customer conversations, prospects frequently asked why they would use the product, indicating a misalignment between the offering and customer needs.
– Takeaway: Prioritize customer validation early. Ensure that customer problems and willingness to pay are established before investing heavily in development. Do not rely solely on a cofounder’s vision—let customer feedback drive product direction. If a partner shows moodiness or misalignment with practical milestones, reassess the collaboration sooner rather than later.
Overall reflections: What I would do differently
– Diversify go-to-market and distribution channels from the outset to reduce dependency on a single ecosystem.
– Implement rigorous cofounder due diligence and define clear, ongoing deliverables for every partner.
– Place customer discovery and value hypotheses at the core of product development. Validate problem-solution fit and willingness to pay before heavy engineering effort.
– Monitor team dynamics and personal alignment. If a partner exhibits persistent misalignment with milestones or product vision, address early and consider restructuring or disengagement options.
If you’re navigating a similar journey, these lessons emphasize disciplined collaboration, market-focused validation, and diversified growth strategies as keys to building sustainable, iterative startups. Would you approach any of these ventures differently based on your own experiences?
