Cognism vs Apollo (2026): Data, Pricing, Compliance

The 30-second answer

Cognism and Apollo solve the same surface-level problem — turning a target account list into contactable humans — but the two platforms sit in different price brackets, cover different geographies, and answer different compliance questions. Cognism is the premium, GDPR-first, EMEA-strong data layer with phone-verified mobiles (Diamond Data) and quote-based enterprise pricing that typically starts around $22K per year for a small team. Apollo is the self-serve, US-strong, all-in-one prospecting suite with a $49/seat entry point, a native outreach sequencer, and a Chrome extension aggressive enough to be its main acquisition channel. If you're an EMEA-focused sales org that needs mobile numbers that actually ring, Cognism wins. If you're a US-based team under 50 people that wants data plus sequences plus a dialer under one login, Apollo wins. Both platforms exist alongside a third layer — relationship intelligence — which surfaces the warm paths your existing team and customers already have into the accounts these tools help you cold-call.

The comparison table (2026)

Pricing verified August 2026 via published procurement data and vendor pricing pages. Both companies have raised entry pricing in the last 12 months — factor 10–15% headroom into any budget model.

The decision tree

You don't need a scorecard. You need to know which of three sentences describes you.

Use Cognism if… - More than 30% of your target accounts are headquartered in the UK, EU, or DACH. - You've had a deal die because a mobile number was disconnected, wrong, or triggered a DNC complaint. - You're in a regulated vertical (financial services, healthcare, insurance) where "how did you get this number" is a question your prospects actually ask. - Your sales cycle is enterprise (7-figure ACV, multi-quarter) — data quality per record dwarfs data cost per record. - Your outbound stack already includes Outreach, Salesloft, or a mature Salesforce install — you don't need Cognism to be your sequencer.

Use Apollo if… - Your ICP is US-first, mid-market or SMB. - Your team is under 50 people and you'd rather have one login than five. - You want a Chrome extension your reps will actually open every day. - You're running a founder-led or lightweight outbound motion and $49/seat is the difference between shipping and not shipping. - You value transparent, self-serve pricing over a 3-week enterprise procurement cycle.

Use both if… - You have a bifurcated ICP (US SMB via Apollo for volume; EMEA enterprise via Cognism for quality). - You want Apollo as your everyday prospecting UI and Cognism as your enrichment API for high-value accounts only. - Your RevOps team is mature enough to route the right accounts to the right provider based on geography, ACV band, or seniority — most teams under $10M ARR won't get the ROI on running both.

The honest third option: where relationship intelligence fits

Cognism and Apollo answer the question "who should I cold-contact?" Both are good at it. Neither answers the question underneath: "who at my target account do we already have a warm path into?"

That's a different tool category. Relationship intelligence platforms pool the collective network of your team, your existing customers, your investors, and your board into a firm-wide graph — then map warm paths into your target account list. When you already have an intro path into a CFO, a warm introduction routed through a mutual connection converts 3–5x higher than the best cold sequence Apollo can generate against the best mobile number Cognism can supply.

The mature 2026 outbound stack doesn't pick between data providers and relationship intelligence. It runs both. Data providers (Apollo or Cognism, or both) answer the accounts where you have no warm path. Relationship intelligence platforms like Boomerang work the accounts where you do — usually 20–40% of your target list, and disproportionately the ones with the highest close rates.

If you're picking your stack from scratch, most Series A–B teams start with one data provider and layer relationship intelligence on top. See the 2026 GTM stack for Series B companies for a full stack diagram, or the modern prospecting stack with RI combo for how the two layers work together.

Where each platform is actually strong

Cognism, in one paragraph. The Diamond Data mobile-verification layer is genuinely differentiated — third-party tests put pickup rates at 87–93% versus Apollo's 72–78%. If your reps make outbound calls, this compounds. The EU/UK coverage is not marketing — Cognism was built in London, and continental European mobile numbers, DACH firmographic depth, and DNC scrubbing against national do-not-call registers are structurally better than any US-first competitor. The tradeoff is procurement friction (annual contracts, quote-based pricing, minimum 5 seats in practice) and a platform surface that stops at the data layer — Cognism isn't trying to be your sequencer.

Apollo, in one paragraph. The best self-serve outbound platform on the market for teams under 50. The $0 free tier alone is genuinely useful for founder-led sales. The Chrome extension is the daily driver — reps live in it, not the main app. The sequencer, dialer, and meeting scheduler are good enough that you don't need Outreach or Salesloft until you're past $10M ARR. The tradeoffs: mobile numbers are patchier (roughly 1 in 4 numbers is wrong or disconnected in independent testing), the EU dataset is shallower, and the "unlimited" credits marketing hides real per-seat throttles. Apollo raised prices in the last 12 months; the effective floor for a 3-seat team on the Organization plan is roughly $4,300/year.

Common failure modes

Buying Cognism for a US-only, sub-50-person team. You're paying enterprise pricing for European data you won't use. Apollo covers the US SMB use case at ~1/5 the annualized cost.

Buying Apollo and expecting European deliverability. The EU records are there, but the DNC-scrubbing rigor isn't the same. If you're cold-calling German or French mobiles, you need Cognism.

Assuming "data provider" is the whole stack. Neither Cognism nor Apollo tells you which of your existing colleagues, customers, or investors already knows the CFO you're trying to reach. That's a separate layer — relationship intelligence — and it consistently produces the highest-converting pipeline in mature outbound orgs.

Ignoring the annual-contract lock-in. Cognism is annual-only. If your team churns, restructures, or shifts ICP mid-year, the seat commitment is stuck. Apollo's monthly billing (at a premium) is genuinely useful when you're still figuring out the motion.

Trusting vendor mobile accuracy claims without a sample test. Both companies market 90%+ accuracy. Both will let you run a 100-record sample against your ideal ICP. Do that before signing anything.

The verdict

Cognism if EMEA and enterprise. Apollo if US and self-serve. Neither if you haven't first checked which accounts you already have a warm path into — that's the layer that converts, and it sits above both.
