What's your minimum product-led motion tech stack?

To support Paperless.io PLG motion, we want to let our product usage data inform our engagement campaigns. So we need an easy way to sync your customer data with our engagement tools. At the moment, we're looking at: • Rudderstack (Data Collection) • Mixpanel (Product Analytics) • Intercom (Product Led Engagement) Does this make sense or do you have any other recommendations? How does your tech stack look like?
