Proving Your Market Size Can Double Your Value

When a buyer evaluates your business, they are looking past what you have already built. However successful you are today, they need to see how much bigger it could become to justify their return. That is where your total addressable market — the full revenue opportunity if you captured all the demand for what you sell — comes in.

If that market looks small, your growth prospects look capped. And if your growth looks capped, so does your multiple.

That was the challenge Tad Fallows faced with iLab, a software platform serving research labs at universities and hospitals. The product worked, customers were sticky and margins were strong. But at first glance the addressable market looked tiny — only a few hundred institutions fitted the profile. Early offers reflected that ceiling, coming in at around three times revenue.

Prove the market, do not just pitch it

Rather than accept the deal, Tad set out to prove the market was larger. Buyers heavily discount hypothetical growth stories — it is not enough to say “we could sell internationally” or “we could upsell more modules”. You need evidence. Here is how he built it:

• Go global, even in small steps. Signing a handful of international customers proved the platform was not confined to one country. Even a sliver of overseas revenue reframed the company as a global solution.
• Show new use cases. By launching add-on modules and winning paying customers for them, iLab demonstrated that existing clients would buy more — turning one revenue stream into several.

These moves transformed the perceived size of the opportunity. Instead of a small, capped niche, iLab could show a credible path into a far larger market with much more upside.

The payoff

With a larger, proven market, the valuation multiple doubled: a three-times-revenue offer became a six-times exit. That is a vast difference in pounds, driven not by short-term sales tactics but by reshaping how buyers thought about the ceiling.

And Tad is not an outlier. Value Builder analytics show that companies which can readily expand into new geographies receive offers around 18% higher on average. In a study of more than 3,000 businesses, those who found it easy to replicate in another region averaged 4.1 times earnings; those who found it hard averaged just 3.5.

The practical move is to start small. Land one or two customers in a new region. Pilot an add-on to prove appetite for more. Do that, and you raise the ceiling on your company's value long before you ever think about selling.
