Case Study: Preply doubles user sign-ups and cuts customer acquisition cost by 50% with TUNE

Preply Increased User Sign-ups 100% and Cut Acquisition Cost 50% with TUNE

Preply, an online language-learning marketplace connecting over 49,000 tutors with learners worldwide, needed a partner-marketing solution that made it easy to recruit and manage diverse partners while supporting customizable payouts, flexible commission tiers, and built-in fraud protection. Their primary goals were to acquire more learners and tutors, reduce advertising fraud, and improve ROI.

Preply implemented the TUNE Partner Marketing Platform—using Connect to rapidly recruit education partners, custom payout structures to optimize commissions, and a creative asset manager plus native fraud and optimization tools. The results: new user sign-ups rose by more than 100% quarter over quarter, customer acquisition cost fell by 50%, and the affiliate program grew to 1,700+ partners (a 122% increase), freeing budget to reinvest and deepen partner collaboration.
