Why are testers so hard to find...

Here's an updated version without "the concept": Hey everyone, Over the past year, my dad and I have been working on a startup called WinByWorking. It transforms your sprint board into a multiplayer video game! We were inspired to create this after seeing how isolated and disengaged my dad’s team became during COVID, where he worked as an agile manager. We’ve completed Version 1 of the product but are facing a big challenge: finding people to test and play it! Does anyone have suggestions on how we can best connect with testers? Also, here’s the link to our demo: https://www.youtube.com/watch?v=UXTLqIiWI9k. If you'd like to try it out, we have a demo sprint board all set up. Just let me know, and we can play a round! Thanks! Hope :)
