What is Cello?
Cello is wrapping its referral platform in AI assistants — for growth managers, referrers, and now AI coding tools via MCP.
Cello has been shipping every week, layering in three parallel AI surfaces: an in-portal Assistant for growth managers, AI-powered sharing-message suggestions for referrers, and a brand-new MCP Server that lets developers' AI tools introspect, validate, and recommend changes to a Cello account. Around those, the team is hardening the developer experience (Event Feed for integration debugging, Flutter SDK in beta) and polishing the referrer widget (dark mode, dual-offer layouts, micro-loop reminders).
What is Privy?
Privy ships A/B testing, MCP integration, and checkout abandonment flows in a rapid automation buildout.
Privy is executing a fast expansion from its popup/form origins into a full e-commerce marketing automation suite. Over the past three months: A/B testing for email campaigns (up to 5 variants with auto-winner selection), MCP server integration for AI assistant access, checkout abandonment flows for Shopify, Facebook Custom Audiences, and dynamic product recommendations in campaigns. The pace is one major feature per two to three weeks.

◆ Current state
Cello has been shipping every week, layering in three parallel AI surfaces: an in-portal Assistant for growth managers, AI-powered sharing-message suggestions for referrers, and a brand-new MCP Server that lets developers' AI tools introspect, validate, and recommend changes to a Cello account. Around those, the team is hardening the developer experience (Event Feed for integration debugging, Flutter SDK in beta) and polishing the referrer widget (dark mode, dual-offer layouts, micro-loop reminders).
◆ Where it's heading
Cello is positioning itself as the AI-augmented referral platform across three personas: program operators get AI recommendations and benchmarks, end-users get AI-assisted personalization, and developers get an MCP Server they can wire into their own coding agent. Performance Benchmarks and Recommendations indicate Cello also wants to own the optimization layer, not just the rails — telling customers what to do next, not only what's happening.
◆ Prediction
Expect the MCP Server and AI Assistant to converge — likely an agentic workflow where the AI Assistant proposes a change and an MCP-connected coding agent applies it. Mobile (Flutter, the existing React Native and iOS/Android components) will probably keep gaining feature parity since referral flows are still desktop-biased today.
Privy
7.5MARKETING
Privy ships A/B testing, MCP integration, and checkout abandonment flows in a rapid automation buildout.
◆ Current state
Privy is executing a fast expansion from its popup/form origins into a full e-commerce marketing automation suite. Over the past three months: A/B testing for email campaigns (up to 5 variants with auto-winner selection), MCP server integration for AI assistant access, checkout abandonment flows for Shopify, Facebook Custom Audiences, and dynamic product recommendations in campaigns. The pace is one major feature per two to three weeks.
◆ Where it's heading
Privy is methodically closing the feature gap with Klaviyo and Omnisend for small-to-midsize Shopify stores. Each release targets a capability that larger platforms already have: A/B testing, abandonment flows, Facebook audiences, AI assistant integration. The MCP server signals that Privy expects its users to manage campaigns via AI assistants, not just the dashboard.
◆ Prediction
Expect SMS A/B testing and cross-channel automation triggers next. The MCP server will likely expand from read-only to write-capable actions within a few releases, enabling AI assistants to draft and schedule campaigns directly.
