API integration customers are our ideal customers, and that is our major focus. We still get a few online signups for small accounts as low as $7/month...thinking about removing that entirely from our offerings. Worth discussing in our session.

We have a few larger clients that use the online app extensively and create support tickets regularly. Profitable, but kind of pulls us in a different direction than API integration partners (no UI required and very little support). Our largest client, LexisNexis, is a hybrid of online app, personal support, and API integration (we actually rewrote all their API integration recently because it had broken, they didn't have internal resources to fix/rewrite it, and it was causing us a great deal more customer support).
