Cello

Cello turns your existing users into a referral channel. It embeds a referral experience inside your product through web and mobile SDKs, gives each user a personal link with automatic attribution, and pays rewards without your team touching a spreadsheet. A second product, Partner Referrals, runs a lighter affiliate program for agencies and consultants who recommend you.

User referrals include branded landing pages, automated reward calculation, payouts by PayPal or Venmo in multiple currencies with tax and compliance handled, and 0% currency conversion or transaction costs. Integrations cover Stripe, Chargebee, HubSpot, Salesforce, Segment and Mixpanel, with SDKs for iOS, Android, React Native and Flutter. Cello publishes customer results such as Hera at 15.8% of ARR growth from referrals and Plancraft at a 5.7 times program ROI.

User Referrals has no free tier. Grow is $200 a month for up to $50,000 in referral ARR. Scale is $750 a month for up to $100,000, and Enterprise is custom with no limit. Partner Referrals starts free with one campaign and five transacting partners, then Plus at $80 a month for three campaigns and 25 partners, Pro at $280 for ten campaigns and 100 partners, and Enterprise on request. Partner payout fees fall from 5% to 2% as you move up.

Cello is the right choice when the referrer is your customer rather than a publisher. For a classic affiliate program with bloggers and creators, pick a dedicated affiliate tool.
