Seamless.AI is a B2B sales intelligence platform that finds business email addresses and phone numbers in real time, mostly through a Chrome extension that works alongside LinkedIn and company websites. For impact organizations the realistic use is narrow but real: partnership and fundraising teams building lists of corporate CSR, ESG, and foundation contacts.
Key features
- Real-time contact search: looks up and verifies emails and direct phone numbers at the moment you search, rather than only reading from a static list.
- Chrome extension: reveals contact details while you browse LinkedIn profiles or company websites.
- CRM integrations: sends contacts to Salesforce and HubSpot, among other tools.
- Credit system: one credit reveals one contact, including email and phone where available.
- Add-ons on higher tiers: buyer intent data, data enrichment, job change tracking, and an AI writing assistant, sold as extras or bundled into larger plans.
Pricing
| Plan | Reported price | Notes |

| Enterprise | Custom quote | Custom credit volumes and account management |
Seamless.AI does not publish all of its prices publicly. The figures above come from independent pricing reviews published in 2026 (for example Landbase and Lindy), not from Seamless.AI itself, so treat them as indicative. The same reviews report that paid plans usually run on annual contracts with a cancellation notice period, and that unused standard credits do not roll over.

Pros and cons
| Pros | Cons |
|---|---|
| The Chrome extension fits naturally into LinkedIn research | Pricing is opaque and mostly quote-based |
| One credit reveals a contact’s email and phone number | Annual contracts and renewal terms are a recurring complaint in user reviews |
| Rated 4.4 out of 5 on G2 across thousands of reviews | Reviewers report bounced emails and outdated numbers, so results still need checking |
| Native Salesforce and HubSpot sync | Reviewers describe coverage as strongest in North America; contacts in Africa and the Middle East may be thinner |
Seamless.AI vs Apollo.io
Apollo.io, which Impact DOTS also covers, pairs a contact database with built-in email sequencing and lists its plan prices publicly. Seamless.AI concentrates on contact discovery and relies more on sales-led, annual pricing. For a small partnerships team that wants to test prospecting without a long commitment, Apollo.io is easier to trial. Seamless.AI is aimed at teams that prospect at volume every day.
Who it’s best for
Corporate partnerships and major-donor teams at larger NGOs, foundations, and impact funds that run structured outreach to companies, especially companies with a strong US presence. It also fits impact ventures that sell B2B services and need a steady pipeline.
Most small NGOs should skip it. If you contact a few dozen organizations a year, the free plan or careful manual research is enough. Data protection matters too: emailing people found through a contact database can raise GDPR questions in Europe and similar obligations elsewhere, so confirm your legal basis before any outreach campaign.
How to get started
Create a free account and test the Chrome extension on 10 to 20 contacts from your real target list, including organizations in the countries you actually work in. Check how many emails bounce before discussing a paid plan, and ask for the contract length, renewal date, and cancellation notice in writing.
FAQ
Is Seamless.AI free? There is a free plan with a limited number of credits, which is enough to test data quality. Exports and higher volumes require a paid plan.
Can I pay month to month? Independent reviews report that paid plans are usually annual contracts. Confirm the term and the notice period before you sign.
Does Seamless.AI cover contacts in Africa and the Middle East? It returns contacts worldwide, but reviewers describe its US coverage as the strongest. Test your own target countries with free credits first.
