What “Radar” means for this product
Radar is home to early-stage products looking to gain traction. Here’s the lowdown of what these deals are and aren’t.
Where it is in its life
Radar products are at the start of their journey. They're fresh on the scene and building a customer base.
How we vouch for it
We've verified the basics and reviewed the listing for safety. Success isn't guaranteed — we haven't fully vetted every claim, feature, or result.
Code & security review
All AI skills are reviewed for security purposes. We do not review software code — partner owns security and what ships.
Refund policy
60-day refund on most deals. AI skills are non-refundable once redeemed.
Pricing
Prices are set by the founder. Simple as that.
Where you'll see it
The Radar section of our site exclusively. These products are in early discovery and not quite ready for the AppSumo limelight yet.
Radar is a discovery engine — because we aren’t vetting these products, our We Got Your Back guarantee doesn’t apply. Should these products show traction, our team will work with theirs to get them ready for the main stage (and protected).
