Kaspr
Buzz AI is an AI-powered multichannel sales engagement platform built by Buzz Outreach Limited, co-founded by Tristan Lefler in 2020 in Brantford, Canada. It enables sales teams to automate and personalize outreach across Email, LinkedIn, Video, and Phone from a single dashboard, backed by a proprietary B2B database of 150 million contacts.
Its AI suite — including Magic Campaigns, Sentiment Detection, and AI Reply Generation — is designed to eliminate the manual work between prospecting and closing.
Kaspr is a B2B contact data enrichment platform founded in 2018 by Allan Benguigui and Omar Ghorbel in Paris, France, and acquired by Cognism in April 2022. It operates as a LinkedIn Chrome extension and web dashboard that surfaces verified email addresses and phone numbers for 200M+ professional profiles in one click — powered by Cognism's network of 500M+ data points from 150+ real-time sources.
GDPR and CCPA aligned by design, it is the leading contact enrichment tool for European B2B sales teams, with a 4.4/5 rating from 750+ G2 reviews.
• Magic Campaigns (AI Campaign Builder) — Generates full multichannel outreach sequences from a simple prompt about your business and target audience, automating copy, channel selection, and targeting logic in one step.
• Multichannel Sequences (Email + LinkedIn + Video + Dialer) — Run synchronized campaigns that touch prospects across Email, LinkedIn social actions, personalized video messages, calls, and SMS from a single campaign workflow — no tool switching required.
• Inbox Sentiment Detection — AI automatically reads and labels every inbound reply as interested, not interested, out of office, or referral so reps can prioritize hot leads without manually reviewing every conversation.
• AI Reply Generation — Generates contextual one-click replies to prospect messages in seconds, handling objections, booking meetings, and advancing conversations at scale.
• Buzz Dialer & SMS (Scale/Unlimited) — Built-in calling with local numbers, up to 5,000 calling minutes on the Unlimited plan, and SMS sequences — so phone outreach lives inside the same platform as email and LinkedIn.
• B2B Lead Database & Data Enrichment — Access 150 million contacts and 11 million companies with enrichment powered by ZoomInfo and Crunchbase integrations; the Unlimited plan includes unlimited data enrichment via Buzz Credits.
• AI Employees (Auto-Booking) — AI agents that learn your outreach style, dynamically adjust targeting, and autonomously book meetings on your behalf — letting reps skip repetitive follow-up and focus on closing.
• Video Outreach Activities — Integrates automated video touchpoints natively into campaign sequences to deliver a high-engagement channel that stands out against standard text-only outreach.
• LinkedIn Chrome Extension (One-Click Enrichment) — Installs in seconds and overlays a Kaspr widget directly on any LinkedIn profile, search result, Sales Navigator list, or event attendee page; returns verified B2B email, direct email, and phone number simultaneously with one click — no copy-pasting or tab switching.
• 500M+ Verified Data Points from 150+ Real-Time Sources — Powered by Cognism's data infrastructure, Kaspr enriches contacts with phone numbers and email addresses sourced and cross-verified in real time from 150+ providers; 90%+ accuracy on European contacts with GDPR and CCPA alignment across all data.
• Unlimited B2B Email Credits (Starter and Above) — All paid plans include unlimited B2B email address lookups per month — no credit counting, no caps, no per-email charges for standard business email addresses; only phone and direct email credits are quota-managed.
• Enrichment Automations (Bulk Enrich from LinkedIn) — Launches background bulk enrichment jobs directly from LinkedIn search results, Sales Navigator lists, LinkedIn Groups, and LinkedIn Events; processes up to 2,500 contacts per run on the Organization plan without manual profile-by-profile clicking.
• CSV Enrichment — Accepts an uploaded CSV file of LinkedIn profile URLs and returns a fully enriched contact list with verified emails and phone numbers; supports up to 10,000 rows per file on the Enterprise plan for large-scale list building.
• Lead Management Dashboard (Lists, Tags, Notes, Tasks) — Stores all enriched contacts in the Kaspr dashboard with organized lead lists, custom tags, notes, tasks, activity history, and a Waiting List that notifies you when previously unavailable contact data becomes available.
• CRM & Dialer Integrations (HubSpot, Salesforce, Pipedrive, Aircall) — Pushes enriched leads one-click directly to HubSpot, Salesforce, Pipedrive, Zoho, Lemlist, and Brevo; integrates with Aircall and Ringover dialers so teams can call enriched contacts without leaving the workflow; Zapier available from Starter.
• Credits Roll Over + Shared Team Credits — Unused monthly credits roll over to the next billing period on all paid plans; all users in an account share from the same credit pool without per-user restrictions, enabling flexible team-wide usage management.
Buzz AI is best suited for sales teams and agencies running high-volume, multichannel outbound where consolidating tools and automating follow-up is a core business need.
• SDR and outbound sales teams at SMBs and mid-market companies — use synchronized Email, LinkedIn, Video, and Dialer sequences to reach prospects across every channel and let AI handle reply triage and follow-up drafting.
• Lead-generation agencies managing multiple client campaigns — run parallel campaign workflows for different clients from a single dashboard, use the unified inbox for reply management, and leverage the 150M+ contact database for rapid list building.
• Recruiting teams sourcing candidates at scale — reach candidates across LinkedIn and email simultaneously with personalized AI messaging and video touchpoints, then use Sentiment Detection to prioritize the most engaged responses.
• Revenue operations leaders evaluating tool consolidation — replace separate subscriptions for email sequencing, LinkedIn automation, a sales dialer, video outreach, and data enrichment with one platform at a potentially lower blended cost.
Kaspr is built for B2B professionals who need fast, accurate, GDPR-compliant contact data from LinkedIn and do not want to leave their prospecting environment to find it.
• SDRs and outbound sales reps — enrich LinkedIn prospects with verified emails and phone numbers in one click during active prospecting sessions, push directly to CRM without manual data entry, and use Enrichment Automations to bulk-process entire Sales Navigator search results overnight.
• Recruiters and talent acquisition teams — source candidate emails and direct phone numbers from LinkedIn profiles, LinkedIn Recruiter Lite, and group member lists at scale with GDPR-compliant data that passes HR compliance reviews in European organizations.
• European B2B sales teams — benefit from Kaspr's strongest-in-class European phone number coverage (powered by Cognism's database which adds nearly 30% more mobile coverage in key European markets) and a data sourcing approach that satisfies GDPR requirements without additional legal review.
• Lead-gen agencies building prospect lists — use CSV Enrichment to process client-provided LinkedIn URL lists and Enrichment Automations to bulk-enrich entire LinkedIn event attendee lists or group member pools, delivering verified contact data files to clients without manual lookup work.

Buzz AI stands out from point-solution competitors by unifying every major outreach channel — including video and phone — under a single AI-powered platform.
• Native Video Outreach in Campaign Sequences — Buzz is one of the very few sales engagement platforms to integrate automated video activities directly into multichannel sequences. Reps can send personalized video messages as part of a drip workflow, not as a separate manual step, which meaningfully increases reply rates on campaigns where text alone goes unnoticed.
• AI Employees for Autonomous Meeting Booking — Beyond message drafting assistance, Buzz's AI Employees are agents that learn your outreach style, dynamically adjust targeting based on engagement signals, and book meetings on your behalf without rep involvement. This moves Buzz beyond a sequencing tool into territory closer to an autonomous SDR.
• Magic Campaigns AI Generation — Sales reps enter a plain-language description of their business and ideal prospect, and Buzz generates a complete, ready-to-launch multichannel campaign — copy, targeting, and channel mix included. Competitors offer AI writing assistance; Buzz generates the entire campaign architecture.
• Proprietary 150M+ Contact Database with Native Enrichment — Unlike most engagement platforms that rely entirely on third-party data, Buzz maintains its own contact database alongside ZoomInfo and Crunchbase integrations, giving teams a single system for data sourcing, enrichment, and sequencing without a separate data subscription.
Kaspr's competitive advantages are rooted in its parent Cognism's data infrastructure and its uniquely deep integration with the LinkedIn ecosystem across all three major LinkedIn account types.
• Deepest European Phone Number Coverage — Powered by Cognism's acquisition of Kaspr and subsequent data merger, Kaspr provides nearly 30% more mobile phone number coverage in key European markets than any competing tool. LaGrowthMachine's independent review confirms approximately 90% accuracy for European contacts — a benchmark that Apollo, Hunter.io, and Lusha do not consistently match for EU-based prospects. For any sales team calling into France, Germany, the UK, or Spain, this coverage gap is a material productivity difference.
• Enrichment Directly From LinkedIn Events — Kaspr lets you bulk-enrich the entire attendee list of any LinkedIn event in a single automated run. You paste the LinkedIn event URL, launch the automation, and Kaspr returns verified email and phone data for every enrichable attendee without individual profile visits. No other mainstream contact enrichment tool offers this LinkedIn Event enrichment natively as a one-click workflow.
• Credits Roll Over Across Every Paid Plan — Unlike Hunter.io, Apollo, and most credit-based enrichment tools where unused credits expire at month end, Kaspr rolls all unused phone and direct email credits forward indefinitely on Starter, Business, and Organization plans. For teams with variable monthly prospecting volume — high some months, low others — this structural feature meaningfully reduces effective cost-per-enrichment over a full year.
• Unlimited B2B Email Credits From $49/Mo — Kaspr includes genuinely unlimited standard B2B email lookups on all paid tiers with no fair-use cap that would realistically affect a standard sales team. Combined with Cognism's 150+ source real-time verification, this makes Kaspr the most cost-effective email enrichment option for teams doing high-volume LinkedIn-native prospecting — provided their primary need is email rather than phone.
Buzz AI integrates natively with the platforms and data sources that B2B sales teams depend on most, plus a broad automation layer for custom workflows.
• LinkedIn (Native Social Outreach) — Automates LinkedIn connection requests, messages, profile visits, post likes, and other social activities as part of campaign sequences directly from the Buzz platform; the Chrome Extension also enriches LinkedIn profiles in-browser.
• Email Providers — Gmail and Outlook connect natively, allowing teams to automate outreach using their existing email domain or a mirror domain; unlimited email account connections are available across all paid plans with up to 250 emails/day on Growth.
• CRM Integrations (Salesforce & HubSpot) — Syncs lead data, deal stages, and activity history bidirectionally with Salesforce (available from Growth) and HubSpot, enabling 2-way pipeline management without duplicate data entry.
• Zapier & Webhooks — Native Zapier integration connects Buzz to 3,000+ external apps for automated lead import, notification triggers, and cross-platform workflow automation; ZoomInfo and Crunchbase integrations power native data enrichment within the platform.
Kaspr integrates natively with the CRMs, sales engagement tools, and dialers that SDRs and sales teams rely on daily, available across all plans including the free tier.
• HubSpot, Salesforce, Pipedrive & Zoho CRM (Native One-Click) — Pushes enriched contact records directly to all four major CRMs from either the Chrome extension or the Kaspr dashboard with one click; contact properties, email, phone number, and LinkedIn URL are auto-mapped to the correct CRM fields without manual configuration.
• Lemlist & Brevo (Native Email Sequence Integration) — Exports enriched prospects directly into Lemlist and Brevo campaign sequences for immediate cold email outreach without CSV export and re-import; enables a one-click find-and-sequence workflow that eliminates manual handoff between Kaspr and your email outreach tool.
• Aircall & Ringover (Native Dialer Integration) — Dials verified phone numbers from Kaspr's lead dashboard directly through Aircall or Ringover with one click; call activity and outcomes sync back to the dashboard so teams can track contact engagement across prospecting and calling in one system.
• Zapier & API (Starter and Above) — Zapier integration (available from Starter plan) connects Kaspr to 5,000+ tools for automated lead routing, CRM enrichment triggers, and Slack notifications; API access (upon request, Starter and above) enables programmatic enrichment for engineering-led GTM teams building Kaspr into custom prospecting workflows.
