Everything about Cello, from programs to channels and pricing.
Sold. When can I get started?
We’re currently in early access and are onboarding a limited number of new customers. If you are interested in being part of our early adopters and helping shape the future of referral experience together, we’d love to have you.
How does your pricing work?
We’ve designed the pricing to be entirely success-based. You only pay us when your program is generating revenue. Our free tier gives you a low friction way to launch and validate if incentivised referrals work for your business.
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 with 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 all countries where PayPal is available. Cello’s referral experience supports localization for users. You can localize and translate every touch point—Just add translations during the setup process.
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.
