Founders reading this will remember the joy of that first validated POC. “You like me! You really, really like me!” If that POC is from an enterprise client or other white-whale situation then the whole experience is magnified and so, too, is the importance the founder might ascribe to what that successful POC signals. Let’s back up though, and examine what that one success actually means, and what it should not be conflated to represent.

We’ve seen this a few times at Well Founded Advisory, and a few examples stick out. Take one founder who had a good existing relationship with the hero customer, so the win did not actually represent the broader market. Yes, this particular win was easy, but the actual client was an exception with the wrong size (enterprise, when the existing product was better suited for mid-market) and a sales cycle that was deceptively short. When we partnered with this founder, we showed that there were lots more promising leads in that mid-market category but realistically we were still looking at two to three months of active conversations before we had a deal signed. Resources should be allocated based on reality to avoid hanging all hopes on just one success.

Another founder was so thrilled to be in open conversation with a white whale that he modified the product significantly to be tailored to that client’s needs. Great, but not repeatable, and not a great use of time. That modified product was so bespoke it would not work anywhere else. Even worse, setting a precedent that a product could be that heavily modified for each individual use case was not sustainable.

A single successful POC is a key first step to market validation, but it’s just part of the equation. It bears examining if others in the market are echoing that enthusiasm and are ready to commit to POCs or trials too. If the market is lukewarm or the product just isn’t gaining traction outside of this one example that promising sign might not actually be representative. Although that can be disappointing, it’s important to note before strategizing further market expansion with valuable time and resources that could potentially be spent opening a market that is ultimately a much better fit.

All those well-worn adages relating to sunk cost fallacy exist for a reason: don’t throw good money after bad, cut your losses, don’t double down on a bad bet and so forth. The reason is that one successful trial probably cost the founder and team incredible amounts of effort. It’s natural to want there to be a justifiable reason that proves it was worth it. However, as those axioms encourage, it is better to learn valuable lessons and move on rather than continue to burn through resources that could be better allocated elsewhere.

It’s also especially hard when you have investors championing that one win because historically, funds love these logos! It makes a great story but the narrative can’t be built around one example no matter how much enthusiasm it generates. It pays to be cautiously optimistic. Communicate the win, absolutely, but make it clear that further market exploration is necessary. Think about how strongly this lands when it can be followed up with demonstrated commitment to validating the market: “On the heels of this success, we are also having conversations with multiple similar profiles to validate this ICP so we can open the market strategically!”

Here are some crucial questions to ask before the enthusiasm for one client drives an entire strategic push that is potentially going in the wrong direction:

Would this same deal have closed with a client without a prior relationship?

Did you have to modify the product to close this deal? If so, is the new version appropriate for a broader market, or does it now represent an entirely bespoke solution?

If the product was heavily modified, can the process be replicated for future clients, or is a dangerous precedent being set that is unsustainable on a broader scale?

A single good story is not a solid enough foundation for building a market. If you want a second opinion before doubling down, let’s connect.
