Why side projects die

Most side projects die after launch, not at launch: they target weak problems, lose users in setup, and leave one person buried in support. (cbinsights.com) CB Insights said in a March 5, 2026 analysis of 431 startup shutdowns since 2023 that 70% ran out of capital, but the deeper causes were poor product-market fit at 43%, bad timing at 29%, and weak unit economics at 19%. The firm said running out of money was usually the final event, not the first mistake. (cbinsights.com) That pattern shows up in smaller software projects too: builders often ship something technically functional before proving anyone urgently needs it. An older CB Insights review of 101 post-mortems found startup failures usually had multiple causes, not one fatal bug. (s3-us-west-2.amazonaws.com) Onboarding is one common break point. In an April 11, 2026 Indie Hackers post, Harsh Garg said 41% of his support tickets came from users in their first 14 days, and he cut that early-ticket volume 44% in six weeks after changing four onboarding steps. (indiehackers.com) That means a side project can look “done” to its maker while still feeling confusing to a new user. If people cannot find a feature, understand the first task, or see the payoff quickly, many leave before the builder gets a second chance. (indiehackers.com) Maintenance is the other trap. A solo founder does not just build features; the same person also fixes bugs, answers email, handles billing issues, updates dependencies, and keeps the app working after every browser, model, or application programming interface change. (cbinsights.com) That workload has grown as more builders use artificial-intelligence coding tools to ship products faster. VibeStack, a discovery site for builders, pitches itself as a directory of 500-plus hand-picked tools and resources, and its catalog shows how many low-code and AI app-building products now promise near-instant launches. (vibestack.io) Faster building does not solve distribution. VibeStack also presents itself as a curated library for non-coders and a place to browse real projects, which helps explain why creators increasingly treat directories as ongoing traffic channels instead of one-day launch events. (vibestack.in) The portfolio approach follows from that math. If one side project stalls on demand, onboarding, or upkeep, a builder with several small products, listings, or experiments has more ways to find users and more chances that one project keeps compounding. (vibestack.in) So the side project graveyard is usually less about code quality than about fit, friction, and follow-through. The projects that last are the ones that keep solving a real problem after the first week, the first bug report, and the first hundred confused emails. (cbinsights.com)
