What is Clay?

Clay lets teams publish workflows as templates and adds healthcare data.

Clay is a go-to-market data platform that combines enrichment, audiences, ads and outbound sequencing. Late October brought Claygent Auto-mode, which picks a model per row for cost, plus MCP client allowlists and per-workflow credit caps. The week of November 2 added Workflow Templates that anyone can copy, a Definitive Healthcare integration, Salesforce traffic through a customer's own proxy, and tags for Audiences segments.

What is Surfer SEO?

Surfer shipped the MCP server its May API release said it was building toward

Surfer has spent 2026 collapsing the distinction between ranking on Google and being cited by AI models, and the last month completes the delivery path it laid out in May. The API rebuild was described at the time as the foundation for an MCP server; that server is now in beta, exposing the Content Editor lifecycle, Auto-Optimize, SEO and AI Search guidelines, AI Tracker visibility data and Recommendations as tools an agent can call. Alongside it, Recommendations began consuming AI Tracker signals to prioritise which mentions to earn and which sentiment to fix.

Clay lets teams publish workflows as templates and adds healthcare data.

◆ Current state

Clay is a go-to-market data platform that combines enrichment, audiences, ads and outbound sequencing. Late October brought Claygent Auto-mode, which picks a model per row for cost, plus MCP client allowlists and per-workflow credit caps. The week of November 2 added Workflow Templates that anyone can copy, a Definitive Healthcare integration, Salesforce traffic through a customer's own proxy, and tags for Audiences segments.

◆ Where it's heading

Clay ships a weekly roundup that alternates between widening its data sources and adding the admin controls larger customers ask for. Workflows have become its main unit, now with budgets, triggers from signals and, with templates, a way to share them between workspaces.

◆ Prediction

Expect templates to grow into a shared gallery and more vertical data providers like Definitive Healthcare to follow.

Surfer shipped the MCP server its May API release said it was building toward

◆ Current state

Surfer has spent 2026 collapsing the distinction between ranking on Google and being cited by AI models, and the last month completes the delivery path it laid out in May. The API rebuild was described at the time as the foundation for an MCP server; that server is now in beta, exposing the Content Editor lifecycle, Auto-Optimize, SEO and AI Search guidelines, AI Tracker visibility data and Recommendations as tools an agent can call. Alongside it, Recommendations began consuming AI Tracker signals to prioritise which mentions to earn and which sentiment to fix.

◆ Where it's heading

The direction is Surfer as a capability an agent uses rather than an application a writer opens. Everything shipped since May points that way: the API first, then the agent interface, with the scoring and guideline logic being the part that stays proprietary. The AI Tracker work suggests the second front is measurement — owning the data on whether models cite you, which is what makes the recommendations worth calling in the first place.

◆ Prediction

Expect the MCP beta to move to general availability with the Agentic Surfy work the May release named, and for AI Tracker data to keep spreading into the surfaces that already existed.
