Clay
GTM data platform with AI research agents, enrichment waterfalls and outbound workflow automation.
From FreeWhy it's on this listModel choice · YesThe buyer picks the model per AI action from a published catalogue spanning several providers, and can substitute their own provider account entirely by supplying an API key.Source ↗
Where it improves on Apollo
- +API access · YesA documented Public API with its own key is available on every plan including free and trial, though tables are read-only and structured queries or paging past 100 rows need Enterprise API table sync.Source ↗
- +Bring your own key · YesBringing your own provider keys is included on every tier down to Free; doing so skips Data Credit charges entirely and only consumes one Action per run, though Clay's own keys run AI roughly twice as fast.Source ↗
Trade-offs against Apollo
- −Seat model · NoClay does not charge per seat at all: every tier from Free upward includes unlimited users and tables per workspace, so there is no seat floor or ceiling and spend scales on Actions and Data Credits instead.Source ↗
- 02
SEOmaticVerified
Autonomous SEO agents that read Search Console data and publish approved fixes into your CMS.
From FreeWhy it's on this listOpt out of training · YesThe vendor trains nothing of its own on your data and routes EU-sensitive workspaces to Anthropic in code, but is explicit that its default Moonshot provider gives no equivalent guarantee.Source ↗
Where it improves on Apollo
- +Getting out · YesContent exports to spreadsheet or JSON on any plan, published work stays in your own CMS if you cancel, and purchased credit packs roll over until used.Source ↗
Trade-offs against Apollo
- −GPT · PartlyOpenAI is used for images, embeddings and some text tasks rather than as the main writer, though a workspace may elect to run its text generation on OpenAI with its own key.Source ↗
- −Certifications · PartlyGDPR compliance is substantiated with a published Article 28 DPA and EU rights process, but the vendor states plainly that it holds neither SOC 2 nor ISO 27001.Source ↗
- 03
ArgorantVerified
Verified B2B contact data, email verification and outbound campaigns, drivable by your own AI agent over MCP.
From $99/monthWhy it's on this listDone-for-you service · YesArgorant Managed is a done-for-you engagement where their team buys domains, warms inboxes, writes and runs campaigns and works replies; it is quoted on a call rather than priced publicly.Source ↗
Where it improves on Apollo
- +Model choice · YesThe buyer picks the model by picking the client: Argorant is the tool layer behind one MCP endpoint and takes whatever agent you already pay for.Source ↗
- +API access · YesA documented REST API is included on every paid plan and on pay-as-you-go, sharing one account and credit balance with the app, with rate limits rising by tier.Source ↗
Trade-offs against Apollo
- −Open source · NoThe terms reserve the software, models and database compilation to Argorant and grant no rights beyond using the service, so nothing is source-available.Source ↗
- −Free tier · PartlyYou can start without a card, but it is a 14-day trial rather than a standing free plan: campaigns pause and unused trial credits expire at day 14.Source ↗
- −Single sign-on · NoSign-in is email and password or Google only; no SAML, OIDC enterprise connection or SCIM provisioning appears on the pricing page, in the docs or in the help centre's account and security section.Source ↗
- 04
Lead Scorer
AI SDR that finds, scores and drafts to B2B leads, with the whole workflow exposed as an MCP server.
From FreeWhy it's on this listGetting out · YesCSV export of leads and companies is a free-plan feature and the Terms point to export before closure; what is not stated is whether monthly credits roll over or expire.Source ↗
Trade-offs against Apollo
- −On the command line · PartlyThere is no Lead Scorer CLI of its own; terminal use means connecting the MCP server from Claude Code or Codex, for which the vendor publishes a plugin bundling the OAuth MCP and its skills.Source ↗
- −Open source · NoThe product itself is proprietary; what is published openly is the playbook layer, 25 downloadable SKILL.md files, not the application the vendor retains rights in.Source ↗
- −A company can buy it · PartlyAn organisation can contract for it and billing details include organisation data, but every published plan is a single-user workspace with one connected inbox; no team or enterprise plan is offered.Source ↗
- 05
Gong
Revenue AI platform with pre-built and custom agents over calls, emails and CRM data.
Why it's on this listAPI access · YesA documented public REST API covers calls, transcripts, users, stats and permission profiles, with Basic or OAuth credentials and published rate limits.Source ↗
Where it improves on Apollo
- +Single sign-on · YesSAML 2.0, OIDC and OAuth 2.0 are all supported with named IdPs, alongside SCIM provisioning and configurable SAML session timeouts.Source ↗
- +Opt out of training · YesNo opt-out is needed because the default is exclusion: Gong states customer data never trains generative models and outputs stay inside the tenant's own data environment.Source ↗
Trade-offs against Apollo
- −Done-for-you service · NoYou buy and run the software yourself; Gong's people provide implementation, training and support around it rather than running revenue work as a service.Source ↗
- −Claude · PartlyClaude is supported as an external AI client that queries Gong's MCP server, not as a model you can point Gong's own AI at; a tech admin must enable the connector.Source ↗
- −GPT · PartlyChatGPT appears only as an MCP client an admin can connect to Gong; Gong does not document running GPT models behind its own features.Source ↗
- 06
RevnuVerified
AI growth agent that runs outbound, paid ads and SEO/GEO with a human approval queue.
From $99/monthWhy it's on this listAPI access · YesA documented REST API with an OpenAPI 3.1 description, bearer tokens, seven scopes and published rate limits covers review, agent chat, results, workflows and leads.Source ↗
Trade-offs against Apollo
- −Free tier · PartlyYou can start without a sales call and the first day is free, but a card is taken up front on Pro and there is no standing free plan.Source ↗
- −Seat model · NoPricing is not per seat at all: one flat account price with no seats to count, though the account itself is capped at twenty-five people.Source ↗
- −Admin controls · PartlyReal constraints exist on the agent — approval queue, per-lane auto-send, a do-not-contact block list, ad caps — but there is no role model to constrain teammates.Source ↗
What to watch for
- ClayCosts scale non-linearly with row count and AI usage; budget the Actions and Data Credits sliders carefully and remember failed lookups still consume credits.
- Lead ScorerPrimary discovery is the French SIRENE registry; web discovery fills gaps but the platform is tuned for French B2B sourcing.
