Case Study: Enpal (solar rental startup) achieves 50% CPA reduction and massive lead growth with Outbrain

Enpal Engages Open-Web Audiences to Massively Scale Lead Volume During Energy Crisis

Enpal, a Berlin-based solar startup that rents photovoltaic systems to homeowners to make renewable energy affordable, needed to drive consumer action and massively scale lead volume amid the energy crisis. The challenge was converting open-web audiences into qualified prospects for its solar rental products while minimizing manual campaign management.

Enpal partnered with Outbrain, leveraging its exclusive publisher partnerships and AI-driven automated bidding alongside high-quality advertorials, quiz-based landing pages, real-people creatives and dynamic headlines. The approach cut CPA by 50%, saved about 5 hours per week in manual optimization, and delivered a large volume of quality leads that helped the company scale during a difficult period for the energy sector.
