9 best Seamless.AI alternatives in 2026
Ranked for a 10 to 300 person B2B team, with each vendor's own published price.
1. Clu: Best for lean GTM teams that want one platform in place of 3 to 5 tools: AI agents
We make Clu. Its 98% verified email and 85% direct dial figures come from our own 500-lead benchmark, which named no other vendor. Each lookup runs through 25+ data providers and stops at the first verified hit, so one row comes back with a verified work email and a phone number. Starter and Pro are self-serve and monthly, and Sequences sends email from your own inbox on every paid plan.
- Waterfall across 25+ providers
- Work email and phone number on one row
- People and Company Search at 0 credits
- Chrome extension
- CRM sync on Pro and Enterprise
Strengths
- Published prices, monthly billing and self-serve signup
- Every seat adds its credits to one shared balance (750 on Starter, 1,500 on Pro)
- Pay per result: search costs 0 credits and a miss costs nothing
Limitations
- No built-in dialer today
- No intent data or technographic filters
- Smaller brand than Seamless.AI or ZoomInfo, with fewer public reviews
2. Apollo.io: Best for reps and small teams that want a contact database and built-in sequences in one tool
Apollo.io combines a large B2B contact database with sequences, a dialer and mailboxes, and publishes its per-user prices. It is the most common Seamless.AI replacement for a rep who wants data and sending in one tool.
- Large B2B contact database
- Built-in sequences and dialer
- Chrome extension
- Free plan
Strengths
- Data, sequences and dialer in one bill
- Published prices and a free plan with 900 credits a year
- Self-serve signup
Limitations
- Per-user pricing grows with every rep
- 78% email match rate in Clu's 1,000-lead March 2026 test
- Organization tier needs 3 users on annual billing
3. ZoomInfo: Best for enterprise sales teams that need intent data, org charts and one vendor on an annual contract
ZoomInfo is the enterprise sales intelligence platform: contact data plus buyer intent, org charts and deep firmographics, sold through a sales cycle on annual contracts.
- Buyer intent signals
- Org charts
- Deep firmographic filters
- Enterprise CRM integrations
Strengths

- Intent data and org charts for account-based selling
- 84% email match rate in Clu's 1,000-lead March 2026 test
Limitations

- Annual contracts quoted per account
- More platform than a small SDR team usually uses
4. Cognism: Best for teams selling into the UK and Europe that need GDPR-compliant data and verified mobile numbers
Cognism sells GDPR-compliant data built around phone-verified mobile numbers, which it calls Diamond Data. Like Seamless.AI it quotes the price on a call, but it is built for selling into the UK and Europe.
- Phone-verified mobile numbers (Diamond Data)
- GDPR and CCPA compliance
- Standard and Pro plans, 5 seats each
- Salesforce and HubSpot integrations
Strengths
- Phone-verified mobiles for EMEA selling
- Compliance documentation European legal teams ask for
- 5 seats included on both plans
Limitations
- No published price and no free plan or trial
- Sales-led buying
- Its main strength is Europe, which a US-only team may not use
5. Artisan: Best for teams that want an AI BDR to run outbound
Artisan sells Ava, an AI BDR that runs outbound for a sales team. Ava searches Artisan's 250M+ B2B contacts or your CRM, enriches leads from 22+ data sources, sends personalized email in your reps' names from your own domains, handles the replies and books meetings on the reps' calendars. Artisan suits a team that wants the outbound run for it, rather than a contact database a rep works one lookup at a time.
- Ava, an AI BDR that runs campaigns, replies and booking
- 250M+ B2B contacts, enriched from 22+ data sources
- Message-level governance: approve every message, lock tone and CTAs, ban phrases
- Enterprise rollout led by a forward-deployed strategist
- Power dialer for reps
Strengths
- Finds leads, sends the emails, handles replies and books meetings
- Approve every message before it sends, with locked tone, CTAs and banned phrases
- Enterprise plan includes a full onboarding build-out, advanced security controls and audit logs
Limitations
- No published prices: every plan is quoted on a sales call

- Enrichment and Prospector APIs
Strengths
- One credit covers email and direct dial
- Published 95% accuracy claim, UpLead's own figure

- Extra credits cost $0.50 to $0.60 each
- No free plan, only a 7-day trial

- Email finder & verifier
- Drip email campaigns
- LinkedIn prospecting extension

Lusha: Clu treats it as a supplier to its waterfall, so it is credited here and left out of the ranking above. Clu is not scored against it.
Why do teams look for a Seamless.AI alternative?
Teams shopping for a Seamless.AI alternative usually want one of three things: a published price, a plan they can start and cancel without a sales call, or contact data they can check before they send. Seamless.AI's homepage FAQ says it is free for up to 50 credits and sends larger buyers to its sales team, and its pricing URL redirects to a demo form (read October 3, 2026). Its pricing page, read September 1, 2026, said one credit covers a phone number and an email.
Seamless.AI describes itself as a real-time search engine for B2B contacts. Reps mostly use it through a Chrome extension, and it now also sells emailing, a built-in dialer, AI agents and an MCP server. It suits reps who look people up one at a time all day. A team that wants a fixed monthly cost or a CRM-ready list in bulk has more choice now.
6 of the 9 tools below publish a dollar price. Each one wins a specific team, named in the picks further down.
How we picked these Seamless.AI alternatives
Every tool here sells B2B contact data that a small or mid-size team can buy today and covers the job Seamless.AI does: finding emails and phone numbers for named people. Prices come from each vendor's own pricing page. Apollo, Snov.io, UpLead, Kaspr and Cognism were re-read on October 1, 2026, Artisan on October 26 (from Artisan, after it retired its self-serve plans), ContactOut on September 22, and Seamless.AI on September 1. Accuracy figures are either the vendor's own published claim, named as such, or one of Clu's own lead tests, named with its sample size. Clu has not run Seamless.AI through those tests.

Frequently asked questions
What teams ask before they move off Seamless.AI.
How much does Seamless.AI cost?
Seamless.AI publishes no dollar price for its paid plans. Its homepage FAQ says it is free for up to 50 credits and points everything above that to sales, and seamless.ai/pricing redirects to a demo form (read October 3, 2026). Every other tool on this page except ZoomInfo, Cognism and Artisan prints its price.
Is Seamless.AI any good?
It is a workable choice for a rep who looks people up one at a time all day and is comfortable buying through a sales call, and one credit covers a phone number and an email. The trade-offs are the buying process and the lack of a public price. Clu has not run Seamless.AI through its own lead tests, so this page makes no accuracy claim about it.
Are there free alternatives to Seamless.AI?
Yes, though every free plan is small. Apollo's gives 900 credits a year with sequences, ContactOut's 5 emails, 5 phones and 5 exports a day, Kaspr's 15 email and 5 phone credits a month, and Snov.io's renewable trial 50 credits. Clu's Free plan gives 50 credits a month after a 14-day Pro trial with 250 credits.
How do Cognism and Seamless.AI compare for verified email?
Neither publishes a price, so the comparison comes down to data and region. Cognism's strength is phone-verified mobiles and GDPR-compliant sourcing for the UK and Europe; Seamless.AI's is real-time lookups from a Chrome extension. Ask both for results on the same 100 records from your own list and compare verified emails and connected dials.
Does Clu have a Chrome extension like Seamless.AI?
Yes. Clu has a Chrome extension, and the same waterfall runs on CSV uploads and in People Search. The finished list goes to Sequences, Salesloft, Lemlist, your CRM or a CSV.
How should an SDR manager test a Seamless.AI alternative?
Run 100 records from your real target list through each trial and count verified emails, bounces on a small send and dials that connect. Then price your volume: seats, phone lookups a month and what a phone costs on each plan. Check the renewal date and notice period on your Seamless.AI order form before you sign anything new.
What Clu runs for you.
One sentence to Clu, our GTM agent, builds an agent. Every Monday it finds 500 new people who match your ICP in 1B+ profiles, gets their emails and phone numbers from 25+ providers, verifies them, adds them to your sequence and posts the run to Slack. All of it is in the 14-day Pro trial. The full feature list is on the pricing page.
