I launched my first productised service for Pipedrive users to visualize the data from sales activities of better using Tableau.
Like all other SaaS platforms, Pipedrive's native reporting and dashboards don't give you the flexibility to visualize just about every thing. This idea came from a heart-felt need from one of my clients, and I thought other Pipedrive users and management teams would find it useful:

Originally, this service was created for 6 fashion eCommerce brands in the UK using the sales data from their Shopify stores. I think you can pick any other SaaS platform and build something similar if the value of insights generated is worth the effort.
