Also, you're adding a discovery platform where businesses have to compete against other businesses for visibility and customers. Why would I choose to, yet again, help create another "aggregator" to the already saturated "aggregator" market (Amazon, Shopify, Google, ChatGPT, etc.)?
Btw, I'm not trying to bash your idea. The reason I ask is that businesses (even smaller ones) don't pay just for software, but for everything else (support, etc), and among those things, software too, and frankly, the main problem 15 years ago was discovery, but with social media (Twitter, ig, and now TikTok), discovery itself is a solved problem.
This marketplace doesn't charge transaction fees because stores already have their own infrastructure. We're just connecting to it. Marketplace operators who fork this can charge flat listing fees or affiliates, but the model works because discovery is separate from infrastructure.
On discovery being solved: social sends traffic to your site, but checkout still happens on your platform. Same here. The difference is stores aren't locked in. They expose a standard interface once and automatically work with every marketplace using that protocol. One store can be listed on multiple marketplaces serving different audiences without any extra integrations.
You're right that businesses pay for more than software. But they also shouldn't have to pay 15-30% transaction fees when they already own the checkout stack. That's the shift.
