Should SaaS founders specialize in a niche or expand to adjacent markets?

An indie SaaS founder building a CRM for service businesses grapples with the strategic dilemma of deep specialization versus broader market expansion. This recurring challenge highlights the tension between focus and growth.

Where It Happened

The debate unfolded on Reddit's r/SaaS subreddit, initiated by user SoloDevArchive in a post titled "Building a CRM for one niche made me question the entire product strategy" on May 8, 2026. The thread garnered significant attention, with dozens of comments from other founders and developers weighing in on the strategic dilemma.

Side A — Steelman: Stay Niche

Some founders argued that staying deeply specialized in a single niche allows a product to achieve perfect fit and become indispensable. By focusing on the unique workflows, terminology, and specific pain points of, for example, cleaning businesses, a CRM can offer a superior experience that generic solutions cannot match. This hyper-focus simplifies marketing efforts, making it easier to identify and target the ideal customer profile (ICP) and craft messaging that resonates directly. Proponents argue that this leads to higher conversion rates, stronger word-of-mouth referrals, and the ability to command premium pricing due to the specialized value offered. The risk of becoming a "jack of all trades, master of none" is avoided, ensuring the product remains highly effective for its intended audience rather than diluting its value by trying to serve too many masters.

Side B — Steelman: Expand to Adjacent Markets

Other participants contended that once core functionality like "scheduling, invoicing, client management, and team features" is built, the marginal cost of adapting it to adjacent service niches (such as plumbers, tile installers, or landscapers) is relatively low, while the potential market expansion is significant. This approach allows founders to leverage their existing development investment across a wider Total Addressable Market (TAM), increasing revenue potential and reducing reliance on the fortunes of a single industry. Expanding thoughtfully, perhaps through configurable terminology or modular features, can prevent the product from becoming "too generic" while still capturing a broader audience. Diversification also provides resilience against downturns in a specific niche and can reveal new product opportunities or synergies across similar business types.

What's Underneath

The core tension often lies in the definition of "product-market fit" itself. For some, fit means solving a highly specific problem for a narrowly defined user with tailored features and language. For others, fit means solving a common problem for a broader category of users, where the underlying solution is largely transferable. Both sides are optimizing for value creation and capture, but they disagree on whether value is best delivered through depth of customization or breadth of applicability. The debate frequently overlooks the founder's own capacity and desire to manage the complexity that comes with either extreme.
