Apollo.io Alternative: Pay Only for the Contacts You Find

Short answer: comparing what each vendor actually publishes, LeadSonar is the strongest pick for outbound teams that want high-quality B2B contact data billed by the workspace instead of by the seat, and here is where Apollo beats it, with the dated pricing from Apollo's own page.

• LeadSonar [Best for teams that want B2B contact data billed by the workspace instead of by the seat]
• Apollo.io [Best for teams that want prospecting, sequencing, dialling and deal management inside a single seat licence]

This page decides on one axis: the billing model. Everything else is context.

LeadSonar bills only when a lookup returns a result, and roughly 85% of contacts resolve across its 18-20 source cascade, with the remaining misses absorbed rather than invoiced. Based on 2026 LeadSonar production data.

All competitor figures verified 20 July 2026 from each vendor's own pricing page. Where a vendor publishes nothing, the cell says so.

Apollo's page states that prices exclude any applicable taxes, and that add-on pricing is introductory and may change. Apollo publishes both a monthly-billing and an annual-billing toggle: the monthly per-seat prices run $65 on Basic, $99 on Professional and $149 on Organization, and annual billing brings each down to the $49/$79/$119 figures in the table above, a savings of roughly 24%.

LeadSonar at a glance

LeadSonar is a lead-intelligence platform. It finds, enriches and scores B2B contacts, then hands them to whatever you already send with. It draws on a 120M+ B2B contact database, plus 45M+ B2C contacts. It pushes one way into HubSpot, Salesforce, Instantly, Smartlead, Maildeck and other outbound tools.

The mechanics that matter for billing:

The waterfall. Give it a first name, a last name and a company domain. The runner cascades through tiers of sources, cheapest first, and stops the moment a source returns a result. Roughly 85% of contacts resolve; the remaining misses are marked not_found and never charged.

Single credit pool. Lead credits reveal a contact. Enrichment credits pay for ICP scoring, company summaries, subject lines and openers, and email or phone enrichment. Search and filtering cost nothing at all. On CSV enrichment the meter runs per filled cell, and unfilled cells are refunded at their per-field weight.

Explainable scoring. Every lead returns an A/B/C/D grade, a 0-100 score, a fit label and a written reason, plus buyer persona and company type. Across the 103,000-contact sample the engine produced 22,772 distinct company-type descriptions, none exceeding 1.8% of the corpus.

Sonya. Natural-language prospecting on every plan including the 7-day free trial, running search, enrichment, scoring and export from one typed request.

Throughput is 23.5 profiles per second sustained on a production 5,000-record bulk run, and about 2 seconds end to end for a single lead.

Apollo.io at a glance

Apollo is a go-to-market platform that puts prospecting, outreach, dialling and deal execution behind one seat licence. Its pricing page groups every tier under four solution areas: Outbound, Inbound, Data Enrichment and Deal Execution, and states that all tiers include every solution.

Basic at $65 per seat per month, or $49 per seat per month billed annually, publishes unlimited sequences, the prospecting, Gmail and Salesforce extensions, a Deliverability Suite with Email Warmup, advanced filters, CRM integrations, Waterfall Enrichment, CSV, CRM and API data enrichment, 6 intent topics and a US dialer where credits apply, with 30,000 credits per seat per year granted upfront.

Professional at $99 per seat per month, or $79 per seat per month billed annually, adds automated workflows, unlimited Gmail and Microsoft mailboxes, 4,000 minutes of call recording with AI insights, and pre-built reports. Organization at $149 per seat per month, or $119 per seat per month billed annually, adds 12 intent topics, 8,000 recording minutes, customizable dashboards, advanced security configurations, single sign-on and bring-your-own LLM API key, under a three-seat minimum.

Apollo publishes four tiers on its own pricing page, with monthly per-seat prices of $65 on Basic, $99 on Professional and $149 on Organization, or $49, $79 and $119 per seat on annual billing, a savings of roughly 24%. Captured from apollo.io/pricing on July 20, 2026.

Billing model compared: per seat versus per result found

This is the whole page. The two models answer different questions.

A per-seat model answers "how many people are allowed to use this?" The invoice is set on the day you sign, before a single lookup runs. Apollo's page is explicit: Basic, Professional and Organization all read "Per seat per month, billed annually", Organization adds "(min 3 seats)", and credits are granted per seat per year.

A pay-per-result model answers "how much data did you actually get?" LeadSonar bills the workspace, shares both credit pools across it, and moves the meter only when a source returns a result.

The seat math at three seats

Both figures use each vendor's entry paid tier at monthly billing, the rate each vendor charges with no annual commitment. Apollo's Basic tier runs $65 per seat per month; LeadSonar's Starter tier runs $29 per month for the whole workspace. Both vendors also publish an annual discount: Apollo's Basic drops to $49 per seat and LeadSonar's Starter drops to $24 per month for the workspace.

| Team size | Apollo Basic, monthly billing | LeadSonar Starter, monthly billing | |---|---|---| | 1 seat | $65/mo, $780/yr | $29/mo, $348/yr | | 3 seats | $195/mo, $2,340/yr | $29/mo, $348/yr | | 5 seats | $325/mo, $3,900/yr | $29/mo, $348/yr | | 10 seats | $650/mo, $7,800/yr | $29/mo, $348/yr |

Apollo figures verified 20 July 2026 from apollo.io/pricing, monthly-billing toggle; taxes excluded per Apollo's page. On annual billing, Apollo's Basic tier runs $49 per seat per month instead.

Cancel one Apollo seat and pay for LeadSonar for a year. At monthly billing on both sides, one Basic seat runs $780 over twelve months, and LeadSonar Starter runs $348 over twelve months for the entire workspace. At annual billing on both sides, the same seat runs $588 and LeadSonar runs $288.

The size of the gap matters less than its shape. One number is a function of headcount and the other is a function of volume. A five-person SDR pod that pulls 3,000 contacts a month pays five times for the privilege under the first model and once under the second.

The second variable: what a miss costs

Normalizing cost per contact found across a seat-based tool and a credit-based tool takes two steps. Fix the team size and the monthly volume, then divide the invoice by the contacts that actually resolved.

Step one is where seat pricing multiplies the numerator. Step two is the denominator, and it is the part almost no comparison page does. If a lookup returns nothing, does it still count against you?

LeadSonar's answer is written into the runner. A lead that every source misses is marked not_found and is never billed. On a CSV pass, unfilled fields are refunded at their per-field weight, so a 30-column enrichment that fills 19 columns bills 19.

What Apollo's pricing page publishes on this question is the allotment and its grant schedule: 900 credits per seat per year granted monthly on Free, and 30,000, 48,000 or 72,000 credits per seat per year granted upfront on the paid tiers. Consult their documentation for how those credits are consumed, because their pricing page does not state it in words we can quote.

On CSV enrichment, LeadSonar bills per filled cell and refunds unfilled cells at their per-field weight, so an enrichment that populates 19 of 30 requested columns bills 19. Based on 2026 LeadSonar production data.

Where each tool fits

LeadSonar is focused lead intelligence: find, enrich and score. Pair it with any sender you already use. That focus is the reason the billing can be pay-per-result.

Choose Apollo if:

If you want prospecting, sending and dialling in one subscription, Apollo is the better fit. LeadSonar does the data half and pushes into your sender; Apollo bundles the sending motion behind one seat licence.

If SSO is a hard requirement for your security review. Apollo publishes single sign-on on its Organization tier. LeadSonar does not publish an SSO commitment on any tier, though it publishes team collaboration and SLA on Pro and unlimited team members on Scale.

If your reps live in the tool all day. A per-seat licence stops looking expensive once every seat is genuinely used across prospecting, calling and pipeline.

Which one fits you

Best for: email-first outbound teams already running Instantly or Smartlead, LeadSonar, because the sending layer is solved and the remaining problem is finding contacts that do not bounce.

Best for: agencies running outbound for five or more clients, LeadSonar, because the workspace bills once while operators rotate, and credit rollover from the Growth tier up means a slow client month is not money burned.

Best for: teams targeting founders, owners and C-suite at small companies, LeadSonar, because in a 37,040-record US outbound sample 95.2% of contacts held founder, C-suite or VP-level-plus titles and 58.7% of rows carried an employee-count field.

Best for: founder-led sales at pre-Series-A companies, LeadSonar, because $29 a month for the workspace with no card on the trial and no seat minimum is a smaller commitment than a three-seat annual floor.

Best for: phone-first outbound teams that dial more than they email, Apollo, because a dialer, call recording and call analytics are published on its tiers and LeadSonar ships no dialling surface.

Best for: teams buying for a whole revenue org of ten or more daily users, Apollo, because the seat multiplier stops mattering once every seat is genuinely in use and the platform replaces three other subscriptions.

Best for: RevOps teams that need enrichment inside a CRM workflow with reporting attached, Apollo, because CRM enrichment, automated workflows and pre-built reports are published on its Professional tier.

We mailed a real 37,040-contact list and only 0.55% of it bounced. That is measured 2026 production data with the sample size stated.

The distinction most comparison pages skip

A syntactically valid email and a deliverable email are different objects. Anything with an at-sign and a dot passes a regex, and RFC 5321 governs the syntax alone. Delivery is a separate question answered only by a mail server.

LeadSonar measures both on the same file. In the 37,040-record outbound sample, 99.98% of contacts had a valid MX record, so only 6 records had no mail server at all. The list was then mailed, and 0.55% produced a hard bounce, 204 rows, dominated by Google's 550-5.1.1 NoSuchUser and 550-5.2.1 DisabledUser responses. The first number is domain reachability. The second is whether the human exists.

That is the number worth demanding from any vendor: what fraction bounced when someone pressed send, on how many records, in what period. Appearance passes a regex. Delivery passes a mail server.

One more figure from the same file, with its denominator. Personalization fields (subject line, opener, two-liner, PS line, buyer persona, company type) were populated on 100% of all 37,040 records. Four columns in that export were empty or constant and were excluded as unusable.

Where LeadSonar Fits

Hold every vendor in this category to one standard: make them state, with a denominator and a date, what happened when their data was actually used. Reach and badges are inputs to the question. The answer is what bounced, on how many records, in what period.

LeadSonar's answer is 0.55% hard bounce on 37,040 mailed records, alongside 99.98% valid MX on the same file, and over 91% of a separate 103,000-contact sample graded B-or-better on ICP fit. Both from 2026 production data. The reach behind that is a 120M+ B2B database plus 45M+ B2C contacts, and the billing follows the same logic: roughly 85% of contacts resolve across the cascade, and the misses are absorbed rather than invoiced.

If your team is paying for seats you do not fill or for lookups that come back empty, the 7-day trial takes no card and grants 1,000 leads, which is enough to run one of your own real lists through the waterfall and check the bounce rate yourself. That is the only comparison that settles anything.

FAQ

How much does Apollo.io cost in 2026?

On apollo.io/pricing captured July 20, 2026, Apollo publishes four tiers with both monthly and annual per-seat prices: Free at $0, Basic at $65 per seat monthly or $49 per seat annual, Professional at $99 monthly or $79 annual, and Organization at $149 monthly or $119 annual with a three-seat minimum. Annual billing saves roughly 24%, and their page states that prices exclude applicable taxes.

What is the cheapest Apollo.io alternative?

LeadSonar's paid entry tier is $29 per month for the whole workspace, with 50,000 lead credits. There are no seat licences, so adding a second or fifth user does not change the invoice. For comparison, Apollo's Basic tier is $65 per seat per month, or $49 per seat per month billed annually, as captured from apollo.io/pricing on July 20, 2026.

Does LeadSonar charge for failed lookups?

No. LeadSonar's waterfall stops on the first source that returns a result, and a lead that no source resolves is marked not_found and never billed. Roughly 85% of contacts resolve across the cascade, and the remaining share is absorbed by LeadSonar. On CSV enrichment the billing is per filled cell, and unfilled cells are refunded at their per-field weight.

Is Apollo.io worth it in 2026?

For a team whose bottleneck is B2B contact data, LeadSonar is usually the better value: a published $29 per month for the whole workspace, pay-per-result billing and a no-card trial, so all your reps cost the same as one. Apollo earns its price when you want prospecting, sequencing and dialling inside a single seat licence and your reps live in the tool all day, which is a broader purchase than a data platform.

What is the best Apollo alternative for agencies?

Agencies serving several clients usually want workspace billing, because operators rotate and client lists do not. LeadSonar bills the workspace at $29 per month on Starter and $79 on Growth, with credit rollover from Growth up. One anonymized data-services engagement ran roughly 5,000,000 enrichments through the same pipeline on a flat package, and a 220,000-record batch plus a 293,000-record gap-fill ran as routine jobs.

Does Apollo.io have a free plan?

Yes. Apollo publishes a Free tier at $0 with 900 credits per seat per year granted monthly, an AI Assistant limited to 5 chats, 2 sequences and basic filters, captured July 20, 2026. LeadSonar's free trial runs 7 days with no card and grants 1,000 leads, including Sonya.

How many contacts does LeadSonar have?

LeadSonar draws on a 120M+ B2B contact database plus 45M+ B2C contacts. The size is the reach: records are revealed at the moment you request them through the waterfall. When we mailed a real 37,040-contact list built this way, only 0.55% of it bounced. That is measured 2026 production data with the sample size stated.

Is Apollo.io per seat or per workspace?

Per seat. Apollo's pricing page states 'Per seat per month, billed annually' on Basic, Professional and Organization, and Organization additionally states a three-seat minimum, captured July 20, 2026. Credits are also granted per seat per year. LeadSonar bills the workspace, and its a single credit pool are shared across everyone in it.

Can LeadSonar replace Apollo for cold email?

Only for the data half. LeadSonar finds, enriches and scores contacts, and pushes them into HubSpot, Salesforce, Instantly, Smartlead and other outbound tools. It does not send email, run sequences or warm up mailboxes. If you want one vendor for data and sending together, Apollo covers both.

Methodology

Competitor pricing. Every Apollo figure was captured from apollo.io/pricing on July 20, 2026 with a headless browser so both the monthly-billing and annual-billing toggles rendered fully. Apollo publishes per-seat prices on both toggles: $65, $99 and $149 monthly for Basic, Professional and Organization, and $49, $79 and $119 annually for the same tiers, a savings of roughly 24% on annual billing. Their page states that prices exclude applicable taxes and that add-on pricing is introductory and subject to change. No review site, forum or listicle was used, because none of them is the vendor and none carries a capture date you can check.

Normalization. Every price comparison uses each vendor's entry paid tier, and the seat math is stated at three seats, because a one-seat comparison understates how a per-seat model behaves on a real sales team.

LeadSonar pricing. Published plans as of July 20, 2026: Free Trial $0 for 7 days, Starter $29, Growth $79, Pro $199, Scale $499, annual billing at roughly 16-17% off. Enterprise is quote-only and excluded from all arithmetic. LeadSonar plan prices were captured from leadsonar.io on July 20, 2026: the month-to-month prices ($29 Starter, $79 Growth, $199 Pro, $499 Scale) are published directly on the site, while the Pro $199 and Scale $499 month-to-month figures are derived from the site's stated 16% annual discount.

LeadSonar performance data. Two anonymized 2026 production datasets. Dataset one: 103,000 ICP-scored B2B contacts, full file streamed, zero pipeline errors, source of the grade distribution (40.6% graded A and 50.8% B, so over 91% at B-or-better) and the company-type counts. Dataset two: 37,040 US outbound records, source of MX validity, hard-bounce rate, title seniority and personalization fill. Throughput of 23.5 profiles per second was measured on a separate 5,000-record bulk run. The 120M+ B2B and 45M+ B2C figures describe the database scale.

Limitations. Both samples are single files reflecting their own composition; dataset two skews toward software, advertising and IT services and toward founder-led small companies, so seniority and industry figures are not population-level. Open tracking was not recorded in that export. The roughly 85% cascade resolve rate is a running production average and varies by list. No competitor data quality, accuracy, match rate or coverage was tested, measured, estimated or claimed anywhere on this page; this comparison is confined to business model and product scope, both checkable in one click.
