B2C & D2C founders! Do you retarget your customers?

if anyone running retargeting ads, or planning to do, or have done in the past, I would like to talk to you. I'm building this solution for people like you. I'd like to brainstorm this idea and build a better product that you "actually" need rather than what I think you will need.
If you're interested, comment here with your email address. I promise you, I won't spam. :)
