GrowSurf is the referral platform that growth and product teams choose when they need speed, control, and results. Launch multi-step, multi-channel campaigns in hours, automate rewards and payouts, and use AI-guided recommendations to tune programs that actually move the needle.
Cello is more suitable for launching an affiliate program that lives in your SaaS product. It’s a low-risk way to validate programs — but if you want more native integrations, deeper campaign logic, and advanced analytics from day one, GrowSurf is the clearer path.

" 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."
