B2B revenue AI platform with $5.2B valuation; predicts in-market buyer intent from anonymous "Dark Funnel" signals to prioritize ABM outreach for Cisco, Zendesk, and enterprise clients.
6sense is an account-based marketing (ABM) and revenue intelligence platform that uses AI to identify in-market buyers, predict purchase intent, and prioritize accounts for B2B sales and marketing outreach — enabling revenue teams to engage prospects at the right time with relevant messaging. Founded in 2013 and headquartered in San Francisco, 6sense has raised over $500 million at a $5.2 billion valuation and serves enterprise B2B companies including Cisco, Zendesk, and Salesforce partners who need to prioritize among thousands of target accounts.\n\n6sense's core capability is its "Dark Funnel" analysis — detecting buying signals from anonymous research activity (website visits, content consumption, competitor comparisons) before prospects fill out a form or contact sales. The platform aggregates intent data from 6sense's proprietary data network, third-party sources (Bombora), and first-party signals to build an AI model that predicts which accounts are actively in a buying cycle and should be prioritized. This enables sales teams to focus outreach on accounts with genuine buying intent rather than spray-and-pray cold outreach.\n\nIn 2025, 6sense competes directly with Demandbase and Bombora for B2B intent data and ABM platform market share, and increasingly with Gong, Clari, and emerging AI sales tools that incorporate intent signals. The company acquired Slintel (technographic data) and Saleswhale (AI email automation) to expand its platform scope. 6sense's 2025 strategy focuses on its Revenue AI platform that unifies intent data, predictive scoring, and outreach orchestration — helping revenue teams compress sales cycles by reaching buyers earlier in their decision process before competitors do.
Salesforce-native sales engagement platform acquired by Clari in 2023. 4,700+ G2 reviews at 4.7/5. Sequences, email tracking, and activity sync built natively inside Salesforce for enterprise teams.
Groove is a Salesforce-native sales engagement platform founded in 2014 and acquired by Clari in August 2023. Operating as Groove by Clari, the platform provides email and calendar automation, multi-step sales sequences, meeting scheduling, and real-time Salesforce activity sync—all built to work natively within Salesforce without data synchronization complexity. Groove has accumulated over 4,700 G2 reviews at a 4.7/5 rating, reflecting strong enterprise user satisfaction.\n\nGroove's Salesforce-native architecture eliminates the sync issues that plague third-party sales engagement tools, writing all activity data directly to Salesforce objects rather than a separate data layer. This makes Groove particularly attractive to enterprise sales organizations that require audit trails, RevOps reporting accuracy, and tight CRM governance. The platform supports multi-step email sequences, phone tasks, LinkedIn steps, and account-based plays, with AI features that surface recommended actions and flag at-risk deals.\n\nFollowing Clari's December 2025 merger with Salesloft, the combined entity now offers overlapping capabilities in sales engagement (Groove and Salesloft Cadence) and conversation intelligence (Clari Copilot and Salesloft Conversations). This consolidation positions the merged company as an end-to-end autonomous revenue platform spanning engagement, forecasting, and pipeline management. Groove remains the preferred choice for enterprises deeply embedded in Salesforce that prioritize native integration over broader platform features.
