Use Hubspot? Could you help?

Hi IHers!

I've built a (free) Hubspot app I hope will act as a way of upselling a side project I'm working on.

The free app will create value for B2B sales teams working leads in the UK, and help me build a segment to market the fuller service to.

If you use Hubspot to support your business/side-project/startup I would love it if you could help me with giving feedback on the installation process.

Bonus if you use Hubspot to do B2B sales in the UK it would be great to understand how this service could work for you (not pitching, just exploring ideas/feedbacK).
