SellSide DB, Acquire.com, and Flippa solve different parts of the SaaS acquisition workflow. Marketplaces (Acquire.com, Flippa) connect buyers and sellers and host the transaction. SellSide DB adds an analyst layer on top - AI buyer thesis, attractiveness scores, semantic search, comparable benchmarks - so you can review dozens of listings in the time it used to take to review three. Here's how the three compare.

When to use SellSide DB
Use SellSide DB when your bottleneck is filtering. If you're sifting through hundreds of listings to find a handful that match your buy box, the AI scores, semantic search, and benchmark layer save days. SellSide doesn't replace marketplaces - it makes them readable at scale.
When to use Acquire.com or Flippa
Use a marketplace when you're transacting. Once you've identified a target on SellSide DB, the actual deal-making (escrow, NDA, asset transfer) happens on the marketplace where the seller is listed. SellSide DB links out to the source on every listing.
Marketplaces are also where you list a business for sale. SellSide DB is buyer-side only.
How they work together
The optimal workflow: filter and analyze on SellSide DB → click through to the source marketplace → run due diligence with the marketplace's tooling → close. You get the analyst layer and the transaction infrastructure both.
FAQ
Does SellSide DB charge a success fee?

Marketplaces show raw listings. SellSide DB adds the analyst layer - AI thesis, scores, benchmarks, semantic search - so you can review 50 listings in the time it takes to read 5 by hand.
Does SellSide DB cover all SaaS marketplaces?
Coverage is being expanded continuously. The dataset is built to source-agnostic, so additional marketplaces can be added without changing the analysis layer.
