In their own words
Factors.ai
Factors.ai is an account intelligence platform that identifies companies visiting a website and brings together cross-channel intent and engagement signals. It collects account-level signals from LinkedIn, Google, Meta and Bing campaigns, G2 pages and uploaded third-party sources. Its buyer-journey view combines account- and user-level engagement from awareness through a won deal, highlighting paths to wins and drop-off points. Predictive scores based on intent, engagement and fit are intended to help prioritize accounts for sales outreach and advertising. Factors says enrichment across multiple providers can reveal more than 75% of anonymous website traffic. It does not identify people individually, though geography and job-title filters can help narrow down likely visitors. Listed integrations include HubSpot, Salesforce, Zoho CRM, advertising platforms, Slack, Microsoft Teams, Segment, G2, Google Search Console, Zapier and Make.com. Web and API access are listed. Factors states it is SOC 2 Type II certified and GDPR, CCPA and PECR compliant. Paid plans start at $199/mo, with a free plan and 14-day trial listed.
