A living library of what we’re learning, building, and testing at Propane — our voice-driven customer intelligence platform.

Here you’ll find:

• Learning notes – insights from customer interviews, research, and product discovery.
• Customer stories – real examples of how teams use Propane to uncover always-on user insights.
• Experiments – things we’re testing across product, GTM, and operations (and what we’re learning from them).
• Playbooks – frameworks and best practices we’ve developed for using voice and AI to stay close to customers.

This space is open by design — part transparency, part collaboration, and part ongoing experiment.

We believe sharing how we think and build helps us (and others) make better decisions. → Explore. Learn. Steal what’s useful.
