Pair Programming Tracking - Is there a market need?

Hello fellow Indie Hackers,
as a Pair-Programming (PP) enthusiast, I developed a PP tracking web application (SaaS).

The product itself is in almost finished MVP status. I even started designing a Landing Page (again, this is more a work in progress, than how it should look in the end)

After I tried to contact possible customers (calling, mailing), roughly 15 developers who have PP experience replied. But not a single one showed interest. I did not try to sell them my product. I rather asked if they see a need for that kind of tool.

So now my questions are:
Does anyone of you see a market need for such a tool?
Do you think 15 noes is enough to bury my idea?
