How a solo SaaS reached $6K MRR in 15 months

TrustMRRR, a SaaS product, reached about $6,000 in MRR after 15 months. The main lesson is to prove that people will pay before spending a long time building. A simple landing page with a Stripe payment button can test whether buyers exist before the product is finished. If the product can be built in two weeks, building first may be fine; if it will take longer, selling first is safer.

Real payments give stronger proof than surveys because they show both demand and the ability to find customers. Growth came from sharing meaningful product updates, recording app changes, posting every extra $1,000 of revenue on X, and explaining lessons learned at each step. Building and marketing need separate time blocks because making the product is often easier than getting people to notice it. Content should be shared across X, Threads, LinkedIn, Bluesky, and Mastodon, while longer-term channels like SEO and GEO should be built after validation because social media algorithms can change.

Short, natural talking-head videos can work even when they are not polished, and AI-written scripts are discouraged. Keeping stable income during the early stage can reduce stress and burnout, while helping other founders can create relationships and future opportunities. The first customers came from posting updates on X, engaging with people, and keeping a product link in the profile and pinned post.
