 > We only provide our default BAA for platform add-on subscribers - customization requires >$20k annual spend. The BAA only remains active for as long as the customer is subscribed to a platform add-on - if they unsubscribe, we send them a message that their BAA will become inactive at the end of the month in which they cancelled. A customer who is on a platform add-on trial (with a credit card in PostHog) is eligible to sign a default BAA, but you should make it clear to them that the default BAA will be voided if/when the platform add-on subscription lapses. If the lead is not sure whether they will need a custom BAA and their usage wouldn't put them at $20K, then it is worth pushing them to get legal feedback by sending them our BAA before moving forward, else you risk spending a lot of time on an evaluation that ends up at $450/month.
