Why not use your own platform? It might come off as a joke, but this is a serious question. Why not dogfood your own needs?

our platform is for developers and other tech specialists, while I'm asking for advice on a sales partner

Perhaps you could leverage the power of the platform to have people come to you?

I've found my business partner through craigslist and its going great, we are in progress of forming an LLC. In fact, I'm on my way to buy 2.5k worth of google play gift cards to send him as his bank account was frozen due to some bank error. We are planning to apply to YC Winter 2022 batch with our prototype

2022 really? thanks for your advice on craiglist!
