Sorry for the delay here! One person you might reach out to is @kirsti.rehler, she’s helped quite a few other folks get going on Tiller 
We’re also always happy to help via chat/email through our official support channels and I’ll include some other resources below.
Check out the Tiller Foundations Guide. It’s where you’ll find quick video demos that cover how to get started with Tiller and how to use the Foundation template for budgeting and tracking.
If you’re using Excel, join us for a live Excel Foundations webinar with a demo and the opportunity to ask questions live. Register at the link (even if you can’t attend) and we’ll send you the recording afterward.
If you’re using Google Sheets, this on-demand Foundations webinar recording is available to watch anytime.
[Edit March 2023] We’re also offering 1:1 coaching for a limited time for an additional fee Tiller Coaching - Tiller
