6sense vs Lusha: pricing, features and which to choose

6sense was founded in San Francisco in 2013 and grew into one of the two largest account-based marketing (ABM) vendors, alongside Demandbase. It raised a $200 million Series E in 2022 at a $5.2 billion valuation. The product watches anonymous research activity across the web, matches it to companies, and tells sellers and marketers which accounts are likely in market and how far along they are. 6sense now calls itself an intelligence engine for agentic go-to-market, and most 2026 releases push its data into other tools, including Claude, ChatGPT and Salesforce Agentforce, instead of asking users to live in its dashboards.

The platform splits into Revenue Marketing and Sales Intelligence. On the marketing side, teams define keywords and personas, 6sense scores accounts into buying stages, and the system builds segments for display and LinkedIn ads, website personalization and email. An account that crosses a threshold becomes a 6QA, or 6sense Qualified Account, and is routed to sales. Sales Intelligence gives reps account pages, a Chrome extension that works inside LinkedIn, Sales Navigator, Salesforce, Salesloft and Outreach, alerts, buying-group discovery and contact data. Credits buy access to emails and phone numbers and power list building. AI Email Agents can write, send and reply to prospecting emails based on intent signals.

The common complaints are cost, a long setup before predictions become trustworthy, and intent signals that some buyers find noisy for niche categories. Contact data coverage outside North America draws criticism on review sites. Demandbase is the closest rival, with similar intent and advertising features and a median contract slightly higher, at about $68,600 according to Vendr. ZoomInfo leads on contact data and is often bought for that alone. Clay and Apollo cover account research and outreach at published prices from under $100 a month. 6sense fits B2B companies with enough deal volume and ad budget to act on account scoring; small teams should start with Apollo or Clay.

Lusha is a B2B data and sales intelligence company founded in 2016 by Assaf Eisenstein and Yoni Tserruya. The company says its database covers more than 515 million business contacts and 29 million company profiles across North America, EMEA, APAC, and LATAM. It reports 280,000 or more revenue teams, 300 employees, and 7 million new signals processed each week. Lusha says email verification ranges from 95% to 98% by region, while direct dial accuracy exceeds 86%. The privately held company says it raised $245 million across a $40 million Series A and a $205 million Series B in 2021. Its customers include sales, marketing, recruiting, and RevOps teams, with access through Workspace, a browser extension, CRM connections, API, and MCP.

A typical Lusha workflow begins with a person, company, domain, or filter-based search. Users preview records, reveal verified emails or phone numbers, save prospects, enrich existing records, and monitor account activity. The browser extension displays contact information while users browse professional-network pages and business websites. Workspace organizes prospecting tables, while CRM integrations move records into connected systems. Developers can use the REST API for search, enrichment, prospecting, lookalikes, decision makers, website visitors, signals, and webhooks. The API supports real-time and bulk operations. Lusha MCP adds a conversational route through compatible AI clients, including Claude, ChatGPT, n8n, and Cursor. It can search, enrich, find lookalikes, pull signals, score lists, and manage Workspace tables, but it does not send messages or add contacts to sequences.

Lusha’s credit model is its main constraint: phone reveals consume five credits, and API charges vary by field and signal activity. The agreement limits data to internal B2B sales, marketing, recruiting, intelligence, and fraud-prevention purposes, and prohibits resale or embedding without written consent. Apollo.io adds email sequences and engagement tools, making it better suited to teams that want prospecting and outbound execution together. ZoomInfo targets larger enterprise deployments with broad intelligence and sales workflows. Cognism offers another enterprise-focused contact data option with compliance positioning. Lusha publishes a free tier and self-serve prices, while its API and MCP materials emphasize search, enrichment, signals, and AI access. Pick Lusha if your team needs credit-based B2B prospecting across web, CRM, API, and MCP workflows.
