How Do I Find My First Customers?

Hi r/startups,

I've just launched a SAAS platform for ecommerce and digital advertising - automation without full black box campaign management or "AI" led decisions.

My question is how do I go about getting people into my platform so I can get feedback/new ideas of things to add? I'm a one man band and am much more comfortable on the technical side than sales etc.

I'm happy to offer a couple of months trial - but am lacking the confidence to do stuff like cold messages on LinkedIn (All I see from my connections is moaning about people selling on there)

Any tips of how I should reach potential customers?

Thanks!
