How does your pricing work?

Our pricing is success-based. What you pay scales with the referral ARR you generate through Cello, so your cost always tracks the revenue the channel is actually bringing in. You start on a low entry plan and move up as the program grows.

Can you talk more about user rewards?

Rewards are designed to be customisable for your individual business needs. We recommend recurring rewards calculated as a % of MRR generated from users they’ve referred. Rewards can be capped by setting a maximum reward limit per referral. Users receive payouts directly to their PayPal or Venmo accounts. Reward options such as gift cards, donations, and product rewards (e.g., discounts) are coming soon.

What languages and geos are supported?

We support rewarding users in Austria, Belgium, Brazil, Canada, Czechia, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, India, Netherlands, Norway, Poland, Philippines, Portugal, Romania, Spain, Sweden, Switzerland, United Kingdom, United States. Cello’s referral experience supports localization for users. We provide English, German, Norwegian, Spanish, French, and Dutch by default, and Cello will help you add additional languages on request.

How do you deal with compliance, legal, and security?

Your privacy and that of your users is our top priority. We offer DPAs with all our plans and are GDPR-compliant with servers based in the EU. We collaborate with data protection as a service provider to comply with international regulations for data protection.
