If you run a newsletter or sell ads for a newsletter and ever wonder 'how can I find new brands to pitch?' this is the answer. Sales Pro is super sick and a massive time saver for seeing who’s got fat pockets. This is not an ad, just an ode to an amazing product that I'm thankful someone built.

Katy Huff, Co-Founder, Madrev

We love Who Sponsors Stuff. We’ve had a great and seamless experience, and the leads we’re getting from this stellar product more than pays for itself!

Several of my clients are using Sales Pro and love it...

Sell a single sponsorship thanks to Sales Pro, and it pays for itself. Sell more than that and it's a steal.
