5 Best Apollo.io Alternatives in 2026

Apollo.io is the self-serve B2B prospecting platform that bundles a large contact database with outreach tooling. Here is the shortlist worth your time, compared on verified pricing, coverage, and the catch each vendor’s own page will not tell you.

The best Apollo.io alternative depends on what you actually use. For pay-per-search data without seats or sequences, 1Lookup exposes prospect search and verified reveals as flat-priced API calls. ZoomInfo is the enterprise-depth upgrade, Lusha the simpler extension-first tool, Hunter the domain-first email finder, and HubSpot's Breeze (Clearbit) the native choice for HubSpot shops.

Disclosure: this site is built by 1Lookup. It appears on this list where it genuinely fits, and we say plainly when a competitor is the better choice.

Why teams look beyond Apollo.io

Phone numbers consume 8 credits vs 1 for a verified email, and enrichment up to 9 credits per record (pricing FAQ), so the advertised credit allowances stretch far less for mobile-heavy or enrichment-heavy workflows (e.g. Basic's 30,000 credits = only 3,750 phone numbers/yr)
Unused credits expire at the end of the billing cycle and do not roll over (per Apollo's ToS as quoted in its knowledge base and about-credits page); phone-number credits are never refunded
Plan gates throttle scale: record-selection limits (25/1,000/2,500/10,000 by tier) cap bulk actions, daily email sends are capped at 250 on both Free and Basic (unlimited starts at Professional), non-Google/Microsoft (SMTP) mailboxes start at Professional (5 per user), and SSO plus advanced security are Organization-only
Monthly billing carries a roughly 25-33% premium ($65 vs $49 on Basic, $99 vs $79 on Professional per seat/mo) and the Organization plan is sold with annual billing only; annual plans are billed upfront per seat
Plans are licensed for internal business use only: powering external products or reselling Apollo data requires a separate custom agreement, and legacy 'unlimited email credit' plans are governed by a fair-use cap (lesser of amount-paid/$0.025 or 1M credits/account/yr for paying accounts)

These are factual scope and pricing characteristics, not knocks; Apollo.io remains the right tool for the buyers described in the verdict section below.

The shortlist, in order

1. 1LookupOur product

Best pay-per-search alternative: prospect data as API calls, no seats

Pick 1Lookup when you want Apollo-grade contact data (1Lookup's prospect products query the same Apollo-backed database) as flat-priced searches and success-billed reveals on shared credits, without per-seat plans or outreach features you will not use.

Starting price: $99/mo for 20,000 credits ($4.95 per 1,000, down to $2.00 on Enterprise)
Free option: Free single lookups via the online tools at 1lookup.io/tools, no account required
The catch: Younger brand with a smaller public review footprint than long-established incumbents

2. ZoomInfo

Best enterprise-depth upgrade with intent and org-chart data

Pick ZoomInfo when you are moving upmarket and need the deepest US coverage, buyer-intent signals, and admin controls, with budget for a sales-quoted annual contract.

Starting price: Core platform: not publicly listed - every contract is sales-quoted. Self-serve GTM AI by ZoomInfo: pay-as-you-go top-ups starting at $20; data credits list at $0.35/record ($0.10/credit limited-time launch promo, auto-applied to your first 5,000), AI credits $0.05/credit flat.
Free option: ZoomInfo Lite: permanent free tier, no credit card, no expiration - 10 credits/mo (25/mo with Community Edition contribution), advanced contact/company search, contact exports, Chrome extension (ReachOut), WebSights Lite (up to 10 visitor reveals/day), email sending, HubSpot CRM integration. GTM AI: 100 data + 500 AI credits free at signup, free search/lookup/find-similar, and free-tier MCP, API, and CLI access (5 req/sec, 5 apps).
The catch: Core platform pricing is not published anywhere: ZoomInfo's own pricing guide states no dollar amounts are listed because pricing is consumption-based and varies by organization; paid plans are "billed annually, not monthly" with "no standard monthly billing option"

Reviewers rate it 4.5/5 on G2 from 9,100+ reviews (verified July 2026). Full review breakdown

3. Lusha

Best browser extension for rep-driven contact grabbing

Pick Lusha when your team's core motion is pulling contact details from LinkedIn profiles one at a time while browsing, and a simple monthly credit tier beats API flexibility.

Starting price: $49.90/mo for Starter with 400 credits/mo (= up to 400 email reveals or 40 phone reveals); $37.45/mo billed annually ($449.10/yr for 4,800 credits/yr)
Free option: Free plan at $0 with up to 40 credits/month (= up to 40 email reveals or 4 phone reveals at current credit costs); includes the browser extension and CRM integrations. Free-plan credits reset monthly and do not carry over.
The catch: Phone numbers cost 10 credits vs 1 credit per email (per the live pricing page), so plan allowances effectively shrink 10x for phone-centric workflows - Starter's 400 credits buy only 40 phone numbers (~$1.25 each)

4. Hunter.io

Best for domain-first email finding with built-in verification

Pick Hunter.io when your prospecting starts from company domains and you want found addresses with confidence scores plus verification in one simple tool, and phone numbers are not the priority.

Starting price: $49/mo for 2,000 credits ($34/mo billed yearly, -30%); 2,000 credits = up to 2,000 email searches or up to 4,000 verifications (verification costs 0.5 credit)
Free option: Free plan: 50 credits/mo (= up to 100 verifications or 50 searches), 1 connected email account, 500 recipients per sequence, basic Discover filters, unlimited team members
The catch: Email-only: no phone number or IP address validation/intelligence

5. Clearbit (HubSpot Breeze Intelligence)

Best for enrichment living natively inside HubSpot

Pick Clearbit (HubSpot Breeze Intelligence) when you run your CRM on HubSpot and want enrichment (now Breeze Intelligence) applied to records and workflows inside the platform itself.

Starting price: Not purchasable standalone; the effective entry point is a paid HubSpot subscription - Core Seats "start at $20/month per seat" at the Starter tier (HubSpot Product & Services Catalog), which includes data enrichment with no per-record charge. Extra HubSpot Credits cost $10 per 1,000-credit capacity pack or $0.010/credit pay-as-you-go
Free option: None. Clearbit's legacy free offerings (free platform, Weekly Visitor Report, TAM Calculator, Connect, free Risk/Name-to-Domain APIs) were sunset April 30, 2025 and free Clearbit accounts are no longer created (help.clearbit.com); HubSpot's free CRM does not include data enrichment (paid tiers only), and "Free users and View-only Seat users cannot use HubSpot Credits" (HubSpot knowledge base)
The catch: Not available outside HubSpot: new customers cannot buy Clearbit standalone ("Clearbit is no longer offering new standalone Clearbit subscriptions" - help.clearbit.com), so Salesforce, Pipedrive, or custom-stack teams are excluded; legacy Clearbit APIs serve existing contracted customers only

Migration effort

If you used Apollo for data only, migration is an endpoint swap: point your enrichment or search calls at the new provider and spot-check a sample of your ICP. If sequences and the dialer are live, plan a real cutover: export contact lists and suppression data, rebuild active sequences on the new outreach tool, and overlap both for one cycle so replies are not orphaned.

Apollo.io alternatives FAQ

What is the best Apollo.io alternative?

It depends on the job. If you mainly consume Apollo's data, 1Lookup offers pay-per-search access to the same Apollo-backed database without seats. If you need deeper enterprise coverage and intent data, ZoomInfo. If you want a simpler extension-first workflow, Lusha; for domain-first email finding, Hunter; and for HubSpot-native enrichment, Breeze Intelligence.

Why do teams leave Apollo.io?

The recurring public-review themes are credit mechanics rather than data quality: phone numbers consume several credits each, exports are capped by tier, and billing disputes are the loudest complaint on consumer-review sites. Teams that only need lookups also end up paying for sequences and dialer seats they never open.

Is Apollo.io's data any good?

Its database is among the largest in self-serve B2B, US coverage is its strongest area, and its G2 ratings are excellent. Like every vendor in the category, accuracy drops outside North America and on fast-moving titles, so test reveals against a sample of your own ICP before committing either way.

When is Apollo.io itself the right choice?

When you want database plus outreach in one place: SDR teams running sequences and calls all day get real value from the bundle, and the free plan plus published per-seat prices make it easy to start. The alternatives here win when you need only the data, only the enrichment, or enterprise depth.
