We are a HubSpot App partner, offering an advanced sales reporting tool embedded in HubSpot. Called Dear Lucy 
We are now thinking of adding support for custom object reporting, so my question would be - do you have a need to report on custom object data and what is it specifically?
Thanks so much!

Hey, @TainaSipilä 
Thanks for sharing. I hope you get some great feedback. Additionally, if you’d like, you can repost your question over in the Third Party apps section. I’ll let the other moderators know in case they see a duplicate post shows up there. — Jaycee
