TL;DR

ZoomInfo's SalesOS plans run on annual, sales-led-only contracts with realistic all-in costs of $30,000-$60,000 a year, putting it out of reach for many SMB and mid-market teams. Apollo.io offers self-serve pricing from a free tier up to $119/user/month (Organization, annual, 3-seat minimum) with a 230M+ contact database and 30M+ companies, and holds the highest G2 rating of the alternatives at 4.7/5 from over 9,600 reviews. Cognism is quote-only but estimated at $15,000-$60,000+/year depending on seats, built around "Diamond Data," its manually phone-verified mobile numbers aimed at UK/EMEA cold calling, and carries a 4.5/5 rating from 1,324+ reviews. Lusha is the cheapest self-serve option, with Starter at $37.45/seat/month and Pro at $52.45/seat/month (both annual), a Chrome extension for pulling verified contacts from LinkedIn, and a 4.3/5 rating from roughly 1,600 reviews, though it lacks built-in outreach sequencing and buyer intent data.

Bottom line: ZoomInfo's high cost and lack of self-serve pricing are exactly why SMB and mid-market teams increasingly turn to Apollo, Cognism, or Lusha depending on whether they need built-in sequencing, phone-verified EMEA data, or the lowest-cost entry point.

Best ZoomInfo Alternatives for 2026: Apollo.io, Cognism, and Lusha Compared

This comparison looks at what each tool actually costs, what you get, and which teams tend to be happiest with each one — based on vendor pricing pages, G2 review data, and published company data, all cited below.

Product Overview

Direct answer: Apollo.io is a combined sales intelligence and engagement platform — database plus sequencing, dialer, and a built-in AI assistant — self-serve from a free tier up through enterprise. Apollo reports a database of 230M+ contacts and 30M+ companies and roughly 100,000 paying customers (Landbase). It carries a 4.7/5 rating from more than 9,600 reviews on G2 (G2 via search snapshot).

Cognism is a GDPR-first data provider best known for "Diamond Data," its manually phone-verified mobile number pool aimed at improving cold-call connect rates, particularly for UK/EMEA contacts (Cognism pricing breakdown, Zeliq). It holds a 4.5/5 rating from 1,324+ reviews on G2 (G2, via search snapshot).

Lusha is a lighter-weight contact database tool, popular for its Chrome extension that pulls verified emails and phone numbers directly from LinkedIn profiles and company sites. It has a 4.3/5 rating from roughly 1,600 reviews on G2 (G2 comparison page).

Quick Answer

  • If you're an SMB or mid-market team priced out by ZoomInfo's $30,000-$60,000/year cost → choose Apollo.io, Cognism, or Lusha, because all three offer lower or self-serve pricing compared to ZoomInfo's annual sales-led-only contracts.
  • If you want a built-in dialer and sequencer alongside your contact data → choose Apollo.io, because it's the only one of the three alternatives with a native sequencer and dialer included, while Cognism and Lusha both require integrating outreach elsewhere.
  • If you need phone-verified mobile numbers for UK/EMEA cold calling → choose Cognism, because its "Diamond Data" is manually phone-verified and purpose-built for improving cold-call connect rates in that region.
  • If you want the lowest-cost self-serve entry point → choose Lusha, because its Starter tier runs $37.45/seat/month annually, undercutting Apollo's $49/user/month Basic tier and ZoomInfo's lack of any published pricing.
  • If buyer intent data matters to your workflow → choose ZoomInfo, Apollo, or Cognism, because all three offer buyer intent data (Apollo includes it in higher tiers) while Lusha doesn't offer it at all.

Pricing Comparison

Direct answer: Apollo.io publishes self-serve pricing: Free ($0), Basic ($49/user/month annual), Professional ($79/user/month annual), and Organization ($119/user/month annual, 3-seat minimum), with monthly (no-annual-commitment) billing running higher — for example $65–$149/user depending on tier (Landbase; Salesmotion). Apollo's split mobile/data credit system means real per-seat costs can run well above the sticker price if phone reveals are heavy (Landbase).

Cognism is quote-only. Third-party pricing trackers estimate a platform fee of roughly $15,000/year for its Standard package and $25,000/year for Pro (with Diamond Data), plus $1,500–$2,500 per seat per year — putting a small team's realistic annual cost between $15,000 and $60,000+ depending on seats and add-ons (Zeliq; Derrick).

Lusha is the only one of the three with published, low-cost self-serve tiers: Free (40 credits/month, 1 seat), Starter at $37.45/seat/month (annual, 4,800 credits/year), Pro at $52.45/seat/month (annual, 7,200 credits/year), and Premium starting at $299.95/month for 5 seats, scaling up with volume; monthly (non-annual) billing runs up to $79.90/user (Landbase; SalesIntel).

Who Should Choose What

Direct answer: Choose Apollo.io if you want one platform that combines data with sequencing, a dialer, and an AI assistant, with a genuinely usable free tier and self-serve pricing — good for SMB and mid-market teams that don't want a sales-led buying process and are comfortable managing a credit system.

Choose Cognism if your team sells into the UK/EMEA and cold-calling connect rate is the metric that matters most; Diamond Data's manual phone verification is the clearest differentiator here, and GDPR-native compliance matters for EU-heavy outbound. It's a weaker fit if you need built-in sequencing or a sub-$15K entry point.

Choose Lusha if you mainly need fast, LinkedIn-linked contact lookups (via its Chrome extension) at the lowest published price point, and don't need built-in outreach tooling or intent data — it's the most budget-friendly self-serve option of the group, though its data-accuracy scores on G2 (7.6/10) trail Apollo and Cognism (Landbase).
