Thanks for the great question. With nearly 90 FINRA regulated funding portals and thousands of broker dealers all eligible to facilitate issuers for their crowdfunding raises, you aren't alone in looking for deals that meet certain characteristics (e.g. impact investments). Luckily, there do exist aggregators that collect data about live offerings and sort them into categories.
Another place where you can learn more generally about companies operating at the intersection of impact investing and crowdfunding is at the SuperCrowd conference where companies, including impact companies with live offerings, pitch, present, and discuss case studies. It's a major gathering of leaders in this sector and you can find more info here: https://thesupercrowd.com
We created a shorter URL for the KingsCrowd search: http://screen.impactcherub.com. We created it for members of the Impact Cherub Club, a group of friends who invest for impact via crowdfunding. We're having a ball and making a difference while we make a few pennies.
