Seamless.AI1Lusha — best Mantis Ai alternative for outbound sales teams that need verified direct-dial phone numbers and work emails while prospecting on LinkedIn, reachable through a Chrome extension rather than a separate export step
Also used for finding business contacts, with a simpler and cheaper footprint than the big platforms. It enriches contacts you already have a target list for; Mantis Ai is aimed at producing that target list in the first place.
Pros
- 290M+ verified contacts across 29M+ companies, with 87.8M contacts in the US, published by Lusha
- Chrome extension reveals verified emails and phone numbers directly on LinkedIn and company websites
- Native connectors for Claude, ChatGPT, and any MCP-compatible AI agent for in-conversation prospecting
- Certified under SOC 2 Type II, ISO 27701, and ISO/IEC 42001, with GDPR and CCPA compliance validated by third-party auditors
- Native integrations with Salesforce, HubSpot, monday CRM, and Zoho, plus a full API
Cons
- Paid tier pricing above the Free plan is not listed on the site; teams over 5 seats must contact sales for a quote
- Revealing a phone number costs 5 credits versus 1 credit for an email, so phone-heavy outreach burns through monthly allotments fast
- Free plan is capped at 40 credits per month, which a single prospecting session can exhaust
- Per-user credit limits and custom plan features are gated behind the Scale tier, which requires a sales conversation
Pricing: Free
2Apollo.io — best Mantis Ai alternative for outbound sales teams that need verified decision-maker emails and phone numbers plus a built-in sequencer to run cold email and dialer campaigns without buying a separate data vendor.
The usual comparison when the need is contact data at scale. Apollo is a large prospect database with sequencing built in; Mantis Ai starts from a described ideal customer and searches live sources instead of querying a stored database.
Pros
- Large, frequently refreshed B2B contact database (240M+ contacts, 30M+ companies) bundled with outreach tools
- Free plan exists with no credit card required, useful for testing before committing
- 200+ integrations including Salesforce, HubSpot, Outreach, and SalesLoft reduce workflow disruption
- Parallel dialer and AI-drafted sequences let small teams run outbound without extra headcount
Cons
- Credit-based pricing (separate export, mobile, and enrichment credit pools) is hard to predict and can force mid-cycle top-ups
- Sending from non-Gmail/Microsoft email accounts requires a paid plan, not the free tier
- Enterprise-grade governance and security features are gated behind a custom-quoted Organization/Custom plan
- Contact data accuracy varies by region and company size, requiring manual verification for some records
Pricing: Free tier · paid from $59/mo (verified )
3Hunter — best Mantis Ai alternative for sales and marketing teams that need to find and verify decision-maker emails at target companies and launch cold email sequences without switching tools.
Overlaps on the contact half of the job - finding and verifying email addresses for a domain. It does not help you decide which businesses to approach, which is the part Mantis Ai is built around.
Pros
- Free tier with 50 credits/month and no credit card required
- Combines lead finding, verification, and cold email sequences in one platform
- Browser extension, Google Sheets add-on, API, and MCP server for AI tools
- Annual billing cuts listed monthly prices by roughly 30%
Cons
- Credit-based pricing model makes costs harder to predict than flat per-seat pricing
- Monthly billing costs noticeably more than annual (e.g., Starter is $49/month billed monthly vs $34/month billed yearly)
- Free plan is capped at 50 credits/month, limiting it to very light use
- No listed native desktop or mobile app; access is via web, browser extension, or API
Pricing: Free tier · paid from $34/mo (verified )
4Seamless.AI — best Mantis Ai alternative for B2B sales development reps and account executives who need to build outbound call and email lists of verified prospects, rather than teams looking to manage existing customer relationships.
Another real-time B2B contact search tool, so buyers weigh the two on data freshness. The difference is the entry point: a search query versus a plain-language description of the customer you want.
Pros
- Free plan gives 50 credits with no credit card required, covering email addresses, cell phones, and export download.
- 100% credit-back protection automatically refunds credits for invalid emails.
- Real-time search engine claims 1.8B+ verified business emails and 414M+ phone numbers, updated continuously.
- Chrome extension finds contact data directly on LinkedIn and other websites while browsing.
- Integrates with 6,000+ tools plus MCP connections for Claude and ChatGPT.
Cons
- No public pricing for Pro or Enterprise plans; both require contacting sales for a quote.
- Free tier's 50 credits are consumed quickly since every email or phone lookup uses one.
- AI Assistant, Data Enrichment, Autopilot, and Buyer Intent Data are paid add-ons, not included by default.
- Advanced org management and dedicated success manager are reserved for Enterprise, not Pro.
