The Marketplace List

I was looking for a list of marketplaces so I could look for opportunities to build B2B SaaS products.

I couldn't find it, so I spent some time pulling one together. Hopefully this is useful for someone else.

Let me know if you have recommendations for which are worth exploring, or which aren't!

Creative & Design Tools

E-commerce & Online Stores

CRM & Sales

Marketing & Email Automation

Business Operations & Finance

Project Management & Productivity

Communication & Collaboration

HR & People Management

Content Management & Web Development

File Storage & Cloud Services

Data & Analytics

Automation & Integration Platforms

Enterprise & IT Systems

    You're onto something. I built Pick an Agency as a directory first, and the real leverage came after indexing enough supply to let buyers see patterns themselves. The marketplace impulse (to take transaction cuts) is tempting, but most directories monetize better by staying free to the buyer side and letting the supply side claim profiles. The data becomes valuable later, not the commissions.
