Cool business model and something that makes sense for more online retailers to adopt. My question is how do you differentiate yourselves from Mirakl (https://www.mirakl.com) and F13 Works (https://www.f13works.com)

We have never seen F13 in a deal but they do seem like a valid alternative. Mirakl starts at $500k/year and minimum three years, and are pretty focused on existing offline retailers moving online and going marketplace, so they are pretty limited in who they can work with.

Our general feeling is that niche / values based aggregators are where the puck is going, as opposed to everyone being a worse version of Amazon, where people are shopping their values more often.

The other thing I would say, not to pick on any one of those offerings, is that we actually have a bunch of prebuilt seller apps to making onboarding easier. To our knowledge, that's unique, most of them just have an API and CSVs where as part of our product includes the seller side integration. Merely offering an API instead of EDI doesn't necessarily solve the problem, most of the sellers don't have ERPs or in-house IT at all so facing down JSON via API instead of X12 via EDI is equally impossible for them.
