We have 150 paying customers and $4k MRR. I finally realized our market is too small.

For the last two years, my co-founder and I have poured everything into our B2B SaaS tool. We built it for a very specific niche: independent veterinary clinics. We launched, iterated based on feedback, and actually got traction. We now have 150 paying customers at $27/month**, bringing us to roughly **$4,000 MRR.

On paper, we have product-market fit. Our churn is low, our NPS is high, and our users genuinely love the product.

But I just ran the market size numbers for our next investor meeting, and I feel sick. There are only about 3,000 independent vet clinics in our target geography. Even if we captured 100% of the market, we would only hit $81k MRR. And it's taking us 6 months and thousands of dollars in marketing to acquire just 30 new clinics.

The math simply doesn't work. We built a great product for a market that is too small to build a venture-backed business. We are essentially running a "lifestyle business" that requires 60-hour work weeks.

Now we are faced with a brutal decision: do we try to pivot the product to serve human medical clinics (a much bigger market with massive compliance hurdles), or do we just sell the company to a larger player in the veterinary space and move on?

For founders who hit this wall: How did you realize your TAM (Total Addressable Market) was too small, and what did you do about it?

Did you pivot to a larger adjacent market? Did you raise your prices drastically to squeeze more out of the niche? Or did you just accept that you built a great small business and stop trying to force hyper-growth?
