Are founders building features instead of viable businesses?

A three-part series on Reddit by a self-described MVP developer argues that most SaaS failures stem from poor positioning and unit economics, not from imperfect code or missing features.

Where it happened

In early July 2026, a three-part series of posts by Reddit user Warm-Reaction-456 gained traction in the r/SaaS and r/micro_saas subreddits. The author, claiming extensive experience building MVPs for founders, presented a framework for why many new SaaS products fail to find a market, attributing the issue to business fundamentals rather than technical execution.

Side A: Business fundamentals are the real product

This position argues that the product itself is rarely the cause of failure. Proponents, represented by the original poster, contend that founders are mesmerized by the ease of “vibe coding” an application without validating the business it's supposed to support. The core argument is that success depends on three non-technical pillars. First is positioning: targeting a specific, narrow audience instead of a general one. As the author notes, “The version for the group sold 22 times more than the general one.” Second is creating a unique offer that doesn't compete on price in a crowded market. Many founders build a generic tool, becoming one of forty similar options where the cheapest wins. Third is viable unit economics. Founders often ignore their customer acquisition cost, celebrating revenue while losing money on each new user. The author describes a common scenario: “You make 44$ in the month but it costs 150$ to get a new customer.” For this side, a product with messy code that nails these three points will outperform a beautifully engineered one that fails them. “I have seen beautifully architected products make $0 and absolute spaghetti code disasters do $80k MRR.”

Side B: The product is the problem

This side represents the implicit strategy of the founders described in the posts. The core belief is that traction is a direct result of product quality and feature set. When a launch is met with silence, the diagnosis is a deficient product. The prescribed solution is to build more, refine the code, and improve the UI. This leads to a cycle of adding features like AI enhancements, dark mode, or unrequested integrations in the hope that one more addition will finally attract users. When that fails, the conclusion is that a more fundamental technical rewrite is needed. The author captures this mindset: “The founders come to me and say, I think I need to build it properly this time.. Maybe the UI needs to be improved.” In this view, the path to product-market fit is paved with code. The business model is assumed to be sound, and the lack of customers is interpreted as a signal to keep building the product until it is compelling enough on its own.

What's underneath

The debate hinges on the definition of a “Minimum Viable Product.” One side defines viability commercially (can it make money?), while the other defines it technically (does it work well and have enough features?). The rise of AI-assisted development tools has made achieving technical viability easier and faster than ever. This allows founders to skip the less tangible, often more difficult, work of market research, positioning, and financial modeling. The ease of building creates a powerful illusion that building is the most important work, obscuring the less glamorous business strategy that ultimately determines if the product survives past launch.

The investor read

The proliferation of AI-native development tools is rapidly commoditizing the technical act of building a SaaS product. This debate signals a market shift where the primary risk and defensibility are moving away from engineering and toward go-to-market strategy. A flood of technically competent but commercially undifferentiated products will likely increase competition and customer acquisition costs for generic tools. The signal is that value is accruing to founders who demonstrate deep customer knowledge in a specific niche and possess a clear, economically viable distribution strategy. Technical execution is becoming table stakes, while mastery of positioning, offer creation, and unit economics is becoming the key differentiator.
