Seamless AI is a real-time B2B contact and company database used by 200,000+ customers, sourced from LinkedIn, job boards, SEC filings, and public web data, and refreshed daily instead of on a static quarterly cycle. It adds job change alerts and buyer intent signals for sales teams doing daily outbound prospecting, primarily SDRs and account executives at B2B SaaS companies.
About Seamless AI
Founded in 2015 by Brandon Bornancin and Granville Schmidt in Columbus, Ohio, Seamless AI raised $4.39M in seed funding from Rev1 Ventures, Right Side Capital Management, and Newark Venture Partners, and has grown to 200,000+ customers. The core product is a real-time B2B search engine sourced from LinkedIn, job boards, news outlets, SEC filings, and direct web scraping, refreshed daily as jobs change and companies raise funding, unlike static data vendors that refresh quarterly. The platform also checks email addresses against mailbox availability and validates phone numbers against carrier databases before serving them up. Its Chrome extension enriches LinkedIn Sales Navigator profiles during prospect research, Autopilot builds fresh daily lead lists from saved filters, and Job Change Alerts flag decision-maker moves so reps can reach out first. Buyer Intent Data and Lead Scoring focus outbound effort on the accounts most likely to convert, and Contact Enrichment fills in missing emails and phone numbers on existing records. Native integrations push discovered contacts into Salesforce, HubSpot, Salesloft, Outreach, and Pipedrive. Seamless AI suits sales development reps, account executives, and sales ops teams at B2B SaaS companies running daily outbound prospecting.
Pricing
Free tier: 50 lifetime credits, not a monthly refresh. Basic is the main paid plan at $147/month on annual billing for 250 monthly credits. Pro and Enterprise are quote-based: Pro typically runs $79-$150 per user per month with a 5-user minimum, and Enterprise pricing is fully custom. Buyer Intent Data and the AI Writer add-on each cost $79-$199 per user per month on top of any base tier. All plans auto-renew and require 60-day written notice to cancel.
Key Features
- 1.7B+ Verified Contacts: Provides access to 1.7 billion B2B contacts with verified email addresses, direct cell phone numbers, and job titles, updated daily from LinkedIn, job boards, and public records.
- Chrome Extension for LinkedIn: Adds verified contact info and company insights directly to LinkedIn Sales Navigator profiles, enabling prospect research without leaving the platform.
- Job Change Alerts: Notifies users within 24 hours when saved prospects or key accounts change jobs, enabling warm outreach to decision-makers at new companies.
- Buyer Intent Data: Identifies 12,000+ intent signals including account growth, funding news, and hiring activity, prioritizing high-probability buying signals for focused outreach.
- Autopilot List Building: Automates daily lead generation by creating fresh smart lists matching saved search filters, reducing manual list-building by an estimated 80%.

Pros
- Daily database refreshes and job change alerts surface job moves faster than typical quarterly-refresh vendors, giving reps first crack at decision-makers who just changed roles.
- G2 rating of 4.4/5 across 5,096 verified reviews, indicating consistent user satisfaction despite known issues with email accuracy and billing practices.
- The Chrome extension enriches Sales Navigator profiles with verified contacts on the same page, skipping manual data entry or tab-switching.
Cons
- Email accuracy runs 20-30% below the marketed 98% accuracy claim, with users reporting matching bounce rates and outdated job titles.
- Billing issues are endemic: auto-renewal without clear cancellation reminders, 60-day written cancellation windows, and pricing changes mid-contract are widely reported across review platforms.
- No built-in outreach sequencing or deal-stage pipeline tracking: once you export a list, follow-up emails and pipeline management need a separate sales engagement tool such as Salesloft or Outreach.
Frequently Asked Questions
What does Seamless AI actually cost?
Beyond the free tier, Seamless AI's paid plans move to quote-based pricing past the entry Basic tier. Pro typically runs $79 to $150 per user each month with a 5-user minimum, and Enterprise is fully custom and sales-assisted. The Buyer Intent Data and AI Writer add-ons each tack on $79 to $199 per user monthly on top of whichever base tier you pick.
What do you get on Seamless AI's free tier?
50 lifetime credits, not a monthly refresh, which is enough to pull data on roughly 50 prospects in total. That covers testing the search engine, the Chrome extension, and job change alerts. Daily prospecting past those 50 lookups needs a paid tier.
Which tools compete with Seamless AI in 2026?
Apollo.io is the closest match, with a similarly sized contact database, a free tier, and built-in email warmup that Seamless AI lacks. Clay suits teams that want waterfall enrichment across many outside data providers instead of one proprietary database. Crunchbase is a lighter option for teams that mainly need company and investor intelligence rather than individual contact records.
Is Seamless AI better than Apollo.io?
Apollo.io bakes email warmup directly into its platform, something Seamless AI doesn't offer without a separate tool. Seamless AI counters with a stronger job change alert system that flags moves fast enough for same-day outreach, plus a database built from daily-refreshed public records rather than a single static crawl. Apollo's published per-seat pricing is generally seen as more predictable than Seamless AI's mix of a flat Basic tier and quote-based Pro and Enterprise plans.
What does it take to start using Seamless AI?
A free account and the Chrome extension, which pulls verified emails and phone numbers straight from LinkedIn profiles as you browse. Save a target list as a filter so Autopilot keeps refreshing it with new matching prospects daily, and connect Salesforce, HubSpot, Salesloft, Outreach, or Pipedrive so discovered contacts sync into your existing workflow. Once the 50 free credits are gone, a paid tier is required to keep prospecting.
Top Alternatives
- Apollo.io: Apollo.io bakes in email warmup and publishes simpler pricing, while Seamless AI answers with Job Change Alerts and a database rebuilt from daily-refreshed public records.
- Clay: Clay blends several outside enrichment sources through one AI agent workflow; Seamless AI is a single proprietary contact database with job-change and buyer-intent signals built in.
