Case Study: International TEFL Academy achieves 1,055% ROI and automates its referral program with GrowSurf

How An Education Company Achieves 1055% ROI using GrowSurf

International TEFL Academy, an award‑winning TEFL certification provider with 21 locations and 25,000 alumni, faced an antiquated, manual referral program that forced their 20‑person sales team to use individual landing pages and manually enter and track referrals after phone calls. Seeking to automate the entire referral process and improve the experience for both salespeople and alumni, ITA evaluated eight referral platforms and selected GrowSurf to run their first fully automated referral program.

Using GrowSurf’s platform (and its direct HubSpot integration), ITA automated referral tracking, launched shareable landing pages and emails, and built custom reports and communications workflows to drive referrals. GrowSurf’s easy campaign setup and responsive support helped ITA achieve measurable impact — a 1,055% ROI (roughly a 10X return) over six months, consistently exceed monthly sales goals (137% average), and gain clear revenue tracking and optimization insights.
