Cello

What Cello does

Cello (legally PowerPlay GmbH) is a Munich-based SaaS company that operates an AI-powered referral platform enabling other SaaS companies to launch and automate user-referral and partner-referral programs. Its product combines embedded web and mobile SDKs (JavaScript; iOS, Android, React Native, Flutter) with a no-code Growth Portal, a Partner Portal for affiliate management, automated payouts via PayPal and Venmo across 60+ countries, and 10+ default languages. Underlying technology includes first-party cookie-based attribution (3-month persistence), webhook integrations with billing providers (Stripe, Chargebee, Paddle, Recurly), CRM connectors (HubSpot, Salesforce), a Zapier link to 5,000+ apps, and an AI layer branded Cello AI that delivers fraud/anomaly detection and category-specific benchmark analytics.

Cello monetizes through a volume-based platform fee that scales with referral impact, supplemented by pass-through advertising services and referral reward administration lines, with monthly invoicing around mid-month. Pricing is not publicly disclosed; enterprise customers access sales-assisted onboarding with SSO, custom implementations, and dedicated customer success. The go-to-market is hybrid: a PLG self-serve motion (SDK live in under 30 minutes, Growth Portal for no-code campaign management) for SMB and mid-market, with direct sales for enterprise.

The company targets a horizontal SaaS customer base and reports notable enterprise logos including Typeform, Miro, Pleo, Veed, Descript, HomeToGo, Moss, Riverside, and Shore, with documented customer outcomes such as 600% YoY referral ARR growth (Moss), 5.7x referral ROI (Plancraft), and 15%+ of ARR driven by referrals (Hera). The legal entity is PowerPlay GmbH, headquartered at Sumpfmeisenweg 3a, 81249 München, Germany, and is GDPR and CCPA compliant with EU-based OVHcloud hosting, while SOC2 Type II certification is in progress.
