Oh god, please don't go paying a bunch of randoms to click around your site. That's like testing if a restaurant is good by paying strangers to eat cold lasagne and tell you it's "interesting."
That sort of thing has its place for usability later, but it won't tell you the real deal: does your thing solve a problem people actually give a damn about? Enough to change how they do stuff or fork out cash?
Here's the proper, less expensive way I've seen work:
Get dead specific about who your customer is. Not "small business owners" - I mean what's their job title, what keeps them up at night, what's their Starbucks order.
Map out the shitshow they're in before your solution shows up. What's the pain? The workaround? The duct-tape fix they're using right now?
Track down 10-20 humans who match that profile. Real ones, not your mum's neighbour.
Ask them how they solve the problem today. Don't pitch your idea - just listen. They'll tell you if it hurts enough.
Watch five of them try to use your site. Let them talk out loud about what they expect at each step. The awkward silence? That's gold.
Give them one clear action - join a waitlist, book a chat, start a trial, pay. Whatever fits.
The signal isn't "they said it was cool." The signal is the right person gets it fast and takes the next step without you explaining like they're five.
An agency can polish the funnel later, but don't outsource this bit. You need to hear the confusion straight from their mouths - preferably while they squint at your landing page.
