Propane

Propane is a Danish startup developing an AI-native customer intelligence platform designed to replace traditional, fragmented data systems. Founded in 2025 by CEO Dennis Green-Lieber, the company aims to provide product and go-to-market teams with continuous, actionable insights derived from customer conversations. The founding team has prior experience from companies including Pleo, Neurons, and Brandwatch.

The company's core service involves deploying autonomous AI agents to conduct voice-based interviews at key moments in the customer journey, such as onboarding, churn, and renewal. These AI agents are trained on a client's specific business data, including CRM, product, and support information, to ask contextually relevant follow-up questions, similar to a human user researcher. This process automates the gathering of qualitative feedback at scale, capturing insights into customer motivations for buying, staying, or churning. The platform then structures these insights and delivers them in real-time to tools like Slack, Notion, and CRMs, enabling teams to act immediately.

Propane positions itself as a next-generation Customer Data Platform (CDP) that not only stores data but actively collects, learns from, and acts on it. This approach contrasts with slower, survey-based tools by offering an always-on system for understanding customer sentiment. In August 2025, Propane announced a €1.2 million pre-seed funding round led by Heartfelt and EIFO, with participation from angel investors. This capital is intended to accelerate product development and expand its early customer base.
