Do databricks partners need to pay for databricks account?

Hi guys, our company is new to databricks and we want to become marketplace provider, so for that we have become databricks partner. and now that we want to develop our app/accelarator that we will put on databricks marketplace, do we need to get a paid databricks account or does databricks provide it for free to their partner companies? We already have free tier account but i don't think it will be possible to develop apps on it and use the free account to deploy app to marketplace. sorry if it is stupid question, but we are still trying to figure out how things work here. submitted by /u/Cap
