Enrichment

Vital signs

Why it's on the table

On the table, Enrichment (En) is seat 31 of 58, in the Sales & Revenue family. It is a stable element — the category has settled, choosing is cheap, and switching is rare. Pick a holder and move on; this is not where your decision budget should go. It is marked essential: a company that leaves this seat empty is running with a gap that compounds. It sits in the mid price band — a real line item that should earn its keep visibly.

Enrichment: the top 5 — v2026.Q3

Edition v2026.Q3 · ranking, pricing and status verified 2026-08-06.

1. 1ClayClay Labs

   Free (100 credits/mo) · Launch from $167/mo · Growth from $446/mo · Enterprise custom, annual

   Best for Founders and GTM engineers who want one spreadsheet-like canvas that waterfalls dozens of data providers, runs AI research agents on every row, and pushes the result anywhere.

   The category-definer: multi-provider waterfalls, Claygent AI research agents, and now MCP for Reps (Claude, ChatGPT, Codex) plus an agent-plugin CLI for coding agents — enrichment as programmable infrastructure, not a database seat. The numbers validate it: 500% growth in 2024, $150M ARR by May 2026, and a January 2026 tender at $5B — 61% above the August 2025 Series C price.

   Watch The 'Clay tax' is real: you pay Clay credits on top of marked-up provider costs, and bills balloon quietly. It is a power tool — teams without a dedicated builder stall in table sprawl. Sequencer and CRM-sync ambitions are creeping into neighbors' territory (Sd, Cr).

   $150M ARR May 2026, up from $108M at end of 2025; 500% YoY growth in 2024 [src] · $100M Series C led by CapitalG at $3.1B post (Aug 2025); employee tender at $5B led by DST (Jan 2026) [src] · MCP for Reps (Claude/ChatGPT/Codex), Claygent Builder, and agent-plugin CLI shipped by mid-2026 [src]

2. 2ApolloApollo.io

   Free (unlimited email credits, fair-use) · Basic $49 · Professional $79 · Organization $119/user/mo (3-seat min)

   Best for Lean teams that want database, enrichment, and outreach in a single tool — the canon 'data + outreach in one' pick, with the most generous free tier in the category.

   250M+ contacts across 60M companies, 4M users at 600k+ companies, and revenue up more than fivefold since the August 2023 Series D (stated May 2026). It is also winning the agent era's distribution game: Apollo runs inside ChatGPT and Claude via MCP, and HubSpot chose it to power the Breeze Prospecting Agent.

   Watch Data quality is uneven outside US mid-market — mobiles trail Cognism in Europe. 'Unlimited' email credits are fair-use capped at 1M/year. Its AI-SDR ambitions blur focus, and there has been no priced round since the $1.6B Series D in 2023.

   $150M ARR May 2025; revenue 'more than fivefold' above Aug 2023 Series D level as of May 2026 [src] · 250M+ contacts, 60M companies, 4M users across 600k+ companies [src] · Selected as data provider for HubSpot's Breeze Prospecting Agent; Apollo MCP live in ChatGPT and Claude (2026) [src]

3. 3ZoomInfoZoomInfo (NASDAQ: GTM)

   Quote-only · credit-based exports · Professional / Copilot Advanced / Copilot Enterprise tiers · annual contracts

   Best for Enterprises that need the deepest US direct-dial and org-chart data, compliance machinery, and a vendor procurement already knows.

   Still the enterprise incumbent — $310.4M Q2 2026 revenue, 1,891 customers above $100k ACV, 76% of ACV upmarket — and the most aggressive incumbent in going agent-native: its GTM.AI 'headless context layer' ships native MCP connectors for Claude, Codex, and Gemini Enterprise, and held the #1 GTM-connector slot in Anthropic's directory for nine straight weeks.

   Watch The core business is flat-to-declining: +1.2% YoY growth, 89% net revenue retention, and a $650.5M goodwill impairment in Q2 2026, plus outstanding securities litigation. Mid-market buyers keep defecting to Apollo and Clay. Negotiate hard — the leverage is yours.

   Q2 2026: $310.4M revenue (+1.2% YoY), 89% NRR, GAAP net loss $643.7M incl. $650.5M goodwill impairment (Aug 5, 2026) [src] · #1 GTM connector in Anthropic's directory for 9 consecutive weeks (Send research, 100k+ snapshots) [src] · GTM.AI context layer: 100M companies, 500M contacts, native MCP for Claude/Codex/Gemini (2026) [src]

4. 4FullEnrichFullEnrich

   Trial 50 credits free · Pro $55/mo (1,000 credits) · Enterprise custom · email 1 credit, mobile 10

   Best for Anyone whose only problem is 'find me the email and mobile for these people' — maximum hit-rate for minimum spend, no platform to learn.

   Waterfall enrichment distilled to its essence: it cascades 20+ providers per lookup and charges only for valid results, which is why it shows up inside other people's stacks — Clay, n8n, Zapier, Make — as the contact-data layer. At $55/mo with unlimited users it undercuts a single seat of most databases.

   Watch A point solution by design: no company database or search of its own worth relying on, so you bring the lists. Mobile numbers at 10 credits each make phone-heavy motions pricier than the headline suggests. Young company, thin public track record.

   20+ providers per waterfall; 'highest enrichment rate in the market' claim; pay only for valid results [src] · Pro $55/mo for 1,000 credits ($0.055/credit); emails 1 credit, mobiles 10, personal emails 3 (Aug 2026) [src]

5. 5Ocean.ioOcean.io

   Pay-as-you-go or from $32/mo (9,000 credits/yr at $0.064) · email 1 credit, phone 10 · unlimited users

   Best for Founders who define their ICP as 'companies like our best customers' — paste your top domains, get AI lookalike accounts, then enrich contacts at them.

   The lookalike-first alternative to filter-query prospecting: AI lookalike filters plus waterfall enrichment from 16+ sources under one credit system, strong in Europe where US-centric databases thin out. Credible enough that Clay itself partnered with Ocean.io for B2B lookalike prospecting.

   Watch Contact depth trails ZoomInfo and Apollo in the US; it is company-first, people-second. Small vendor — most capability claims are single-source from its own site. No orchestration layer; treat it as a targeting engine feeding a bigger stack.

   AI lookalike filters + waterfall enrichment from 16+ data sources; $0.064/credit at 9,000-credit annual minimum (Aug 2026) [src] · Clay partnership for B2B lookalike prospecting (2026) [src]

Enrichment: the top 8 compared

Edition v2026.Q3 · ranking, pricing and status verified 2026-08-06.

How to choose your enrichment

If you have a GTM engineer — or a founder willing to become one — and more than one data source

Clay Growth. Treat provider credits as COGS, set rollover alerts, and feed it Ocean.io lookalikes when filter queries stop describing your ICP.

If you are pre-seed and doing your own outbound this quarter

Apollo free or Basic at $49 — database, enrichment, and sequences in one seat. Graduate to Clay when you outgrow single-source data.

If your lists exist and the only gap is emails and mobiles

FullEnrich at $55/mo (BetterContact is the runner-up) — a 20-provider waterfall beats any single database on hit rate, per the whole market's move to waterfalls.

If enterprise procurement, compliance review, or US phone coverage decides

ZoomInfo — and negotiate hard: 1.2% growth and 89% NRR (Q2 2026) means the leverage sits with you.

If you already run HubSpot

Turn on Breeze Intelligence credits and the Apollo-powered prospecting agent before buying any standalone tool — the ex-Clearbit engine is already in your CRM.

Enrichment: the category in numbers

Edition v2026.Q3 · ranking, pricing and status verified 2026-08-06.

• Sales intelligence market $4.99B in 2026 → $9.15B by 2031 (12.89% CAGR) [src]
• Clay: $108M ARR end-2025 → $150M by May 2026; $5B employee tender (Jan 2026) just five months after the $3.1B Series C [src]
• Apollo revenue up 'more than fivefold' since Aug 2023 Series D (company statement, May 2026); still valued at 2023's $1.6B on paper [src]

• Data providers are becoming embedded layers: Clearbit dissolved into HubSpot Breeze (2024), Apollo now powers HubSpot's Breeze Prospecting Agent (2026) [src]

Enrichment: method & sources

Charter: ranked on data coverage/hit-rate, workflow leverage per dollar, agent-readiness (MCP/API), and momentum; no affiliate consideration. Pricing caveat: apollo.io/pricing renders client-side, so Apollo tier prices ($49/$79/$119 annual) are taken from G2's pricing snapshot — re-verify at renewal; ZoomInfo, Cognism, and Common Room publish no prices at all. Source caveat: Clay and Apollo ARR figures are Sacra (aggregator) estimates quoting company statements — no audited numbers exist; ZoomInfo's #1-connector study was vendor-amplified (research by Send). Conflict resolved: Clay's valuation appears as $3.1B (Aug 2025 Series C) and $5B (Jan 2026 tender) in different sources — both are real, the tender is secondary-market pricing, not a priced round; we cite both. The known claim 'Clay $100M Series C at $3.1B' checks out (CapitalG, Aug 2025). Kaspr ownership listed as Cognism per its 2022 acquisition; Kaspr's own homepage is ambiguous about branding. Scope pointers: AI SDRs that use this data to send (Artisan, 11x, Amplemarket, and Unify's outbound half) → Sd; CRMs that store it (Attio, HubSpot) → Cr; intent/ABM suites (6sense, Demandbase, Bombora) have no home element and get no entries here. Findymail's advertised entry price roughly doubled ($49-class to $99 Starter) versus 2024-era coverage — vendor page wins. Ranking criteria: verified commercial traction, independent satisfaction surveys, agent benchmarks, and founder-fit (price floor, lock-in, surfaces). Editorial, never paid — the charter. Machine-readable twin: en.json.

Our take

Clay compressed a three-person SDR function into a part-time ops role. This is what 'agents instead of headcount' looks like in sales.
