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 Clay?
Clay closes the data-to-execution gap: Sequencer 2.0 ships outbound natively
Clay has moved well beyond enrichment. The last two months confirm it is now a GTM execution platform: Sequencer 2.0 runs cold outbound sequences inside the same workspace where data is enriched; Clay Ads 2.0 pushes audiences to six ad platforms; Claygent gained programmable Skills for repeatable AI-agent workflows. The MCP integration now supports cross-entity search from Claude and ChatGPT, positioning Clay's data as infrastructure for AI-native sales stacks.

◆ 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.

Clay closes the data-to-execution gap: Sequencer 2.0 ships outbound natively
◆ Current state
Clay has moved well beyond enrichment. The last two months confirm it is now a GTM execution platform: Sequencer 2.0 runs cold outbound sequences inside the same workspace where data is enriched; Clay Ads 2.0 pushes audiences to six ad platforms; Claygent gained programmable Skills for repeatable AI-agent workflows. The MCP integration now supports cross-entity search from Claude and ChatGPT, positioning Clay's data as infrastructure for AI-native sales stacks.
◆ Where it's heading
Each release closes one more gap between data preparation and campaign execution. Functions replacing legacy Recipes signals a push toward developer-grade reusability, which opens the door to a template or marketplace ecosystem. The addition of Snowflake AI-generated SQL and SOQL imports suggests Clay is building toward owning the data pipeline upstream of CRM, not just the enrichment step inside it.
◆ Prediction
The logical next move is a native HubSpot or Salesforce bidirectional sync—moving beyond Pardot to cover the CRM record itself. Without it, users still need a separate system to track engagement after sequences fire. A deeper CRM write-back would complete the loop Clay has been building.
