Pricing Transparency: GrowSurf publishes all plan tiers and pricing on its website. Ambassador lists starting prices, but full quotes require a sales conversation.
Fraud Protection: GrowSurf automatically blocks burner emails, applies IP thresholds, blocks data-center IPs, and lets you tag fraud manually. Ambassador provides fraud and incentive controls as part of its enterprise tooling.
Automation & AI: Both platforms include automation and AI — but they focus on different problems. GrowSurf provides marketer-facing AI tools (reward recommendations, promotional-copy suggestions, and landing-page assessments) to help teams optimize campaigns quickly. Ambassador offers Hiro, an AI assistant tuned for customer relationships that generates prompts and subject lines, predicts next-best-actions and reward eligibility, and summarizes sentiment and routes follow-ups to Sales or Support.
Ease of Setup: GrowSurf is self-service – you can be live in hours. Ambassador offers extensive onboarding and managed services for larger programs.
Team Access & Roles: Granular team roles are built into GrowSurf plans from the start. Ambassador supports role-based security and advanced enterprise controls depending on the package.
Flexibility & Rewards: GrowSurf supports multi-step campaigns, dynamic rewards, automated payouts, and offline triggers out-of-the-box. Ambassador supports highly customized workflows and advocacy use-cases, often through higher tiers or managed services.
" I had about ten other referral software providers I looked at. We chose GrowSurf because it was something we could customize without having to get developers to build the whole thing out. The price was another big plus for us."
"We use Growsurf to track ALL of our referrals, from paid acquisition channels to newsletters. GrowSurf is responsible for 15% of our new ARR from the last six weeks."
" No need to compare other referral marketing solutions. I've compared them all, and we went with GrowSurf.…Their quick-campaign creation and super fast customer support are amazing. Value for price is also unmatched."
