How to start - App for entrepreneurs

Hi everyone,

I’m in the early stages of developing a platform that connects small, emerging brands (both product-based and service-based) with independent investors who are specifically looking to support smaller businesses.

The idea is to create a more transparent and trust-based space where:

• Brands can create verified profiles
• Investors can clearly state their focus, ticket size, and involvement level
• Both sides can connect based on aligned values, sector, and growth stage

I’m currently at the “how do I structure this properly from the start?” phase - especially around things like:

• What features are absolutely essential in version 1?
• What builds the most trust between founders and investors?
• Common mistakes in marketplace-style platforms?
• Legal considerations I should be aware of early?

I’m intentionally keeping the concept lean for now, and I don’t want to overbuild before validating the demand.

For those who’ve built platforms, marketplaces, or worked in startup/investor ecosystems — where would you start? What would you prioritize first?

Appreciate any insights 🙏
