In their own words

Clay

Clay turns a business’s Google listing, photos, reviews, and hours into a live website. A business can preview and edit the generated site before claiming it, without signing up, giving an email address, or paying. Users can change words, images, colors, and sections directly on the live site, including from a phone. Clay says it rereads the Google listing nightly to refresh ratings and reviews and update SEO information. It can create pages for services and towns, add a sitemap and structured data, and run a weekly audit to find and repair problems. Sites can include bookings and a shop with product options and a basket; Clay says it takes no cut of sales. Hosting is included. Businesses without a Google listing can start with a blank site. The free plan provides an editable site on a name.clay.site address. Pro costs €29/mo and adds a custom domain, bookings, menu, shop, SEO, weekly audit, visitor numbers, and an email list. Clay says users own their site content, domain, and email list, but does not promise a Google search ranking position.

OpenGTM

OpenGTM is an open-source, self-hosted workspace for go-to-market teams and their agents. It handles lead sourcing and enrichment, AI research with cited answers, buying-intent tracking and sending qualified records to other tools. Workbooks combine imports, formulas, HTTP columns, enrichment waterfalls, AI research and output columns, with estimated spend visible before runs. Teams can segment live audiences, monitor hiring and buying signals, and schedule refreshes and automations. Listed activation destinations include HubSpot, Salesforce, Slack, Sheets, Airtable, Instantly, Smartlead, webhooks, warehouses and consent-gated ad audiences. The workspace is also available through REST, webhooks and an auditable MCP server with scoped read and write access. The project says data remains on the user's infrastructure and external calls use provider keys selected by the user. Teams can set workbook budgets to stop paid calls at a ceiling, although provider charges may apply. The software is free under AGPL-3.0. Installation requires Git, Docker with Compose v2 and roughly 4 GB of RAM. The project is pre-1.0; public multi-tenant hosting needs further work beyond team-controlled Compose deployment.
