Warmly Review, Pricing & Alternatives (2026)

Warmly was founded in 2020 by Max Greenwald, Carina Boo, and Alan Zhao. The company announced an $11 million Series A in October 2023 and a $6 million Series A+ round in February 2025, bringing reported funding to $17 million. In 2024, Warmly reported more than 300 customers, $3 million in annual recurring revenue, and a global team of 50 people. The company is based in San Francisco and was built for B2B sales and marketing teams. On June 30, 2026, Warmly announced an agreement to be acquired by HubSpot. It says existing contracts, pricing, account teams, product experience, and integrations remain unchanged during the transition.

Warmly begins with a website snippet and connected data sources, giving revenue teams a way to turn visitor activity into operational signals. It can identify companies and, through permitted methods, contacts, then apply ideal customer profile filters and intent signals to prioritize activity. Teams can send real-time alerts to Slack, route leads into customer relationship management systems, and activate follow-up through webhooks. Inbound Chat adds an AI chatbot, live Warm Calling, chat metrics, and automated email follow-up, supporting conversations and qualification while visitors are active. Retargeting supports email, LinkedIn, and advertising workflows for continued engagement. Integrations include Salesforce, HubSpot, Marketo, Outreach, Salesloft, Apollo, 6sense, Clearbit, Bombora, Demandbase, Slack, Microsoft Teams, and ActiveCampaign.

Warmly’s current product language includes AI Web-Deanonymization, Inbound Chat, and AI Inbound Autopilot. Inbound Chat includes one AI Studio Agent, while Autopilot adds unlimited agents, goal setting, qualification, decision-making, mini-demo slide generation, written chat follow-up, automated email generation, and chat improvement. Warmly describes a Context Graph with more than 220 million people profiles, 40 million company profiles, and 33 million annual intent signals. Its Trust Center lists SOC 2, GDPR, CCPA, and EU Data Act materials, giving buyers reference points for security and privacy review. Company-level JavaScript identification does not identify individuals by itself. Person-level identification comes through other permitted methods, so teams must evaluate consent, notices, and applicable privacy obligations before using those capabilities.

Warmly publishes a free plan and three main paid product levels. Free costs $0 and identifies up to 500 website visitors monthly at company level, with real-time Slack alerts but no automation. AI Web-Deanonymization starts at $10,000 annually with annual billing, or $4,875 quarterly, and includes at least 10,000 monthly credits. Inbound Chat starts at $20,000 annually, or $6,500 quarterly. AI Inbound Autopilot starts at $30,000 annually, or $9,750 quarterly. GTM Signals, the 24/7 Video Chat Agent, and Warm Experiences each cost $10,000 annually. These options let teams begin with basic identification or add chat, automation, signals, and personalized experiences as operational needs expand. Credit use and privacy requirements need active oversight.

Warmly’s main tradeoff is price combined with operational breadth. Paid entry is high for teams seeking visitor identification alone, and credit consumption requires monitoring so usage stays aligned with traffic and campaign volume. RB2B concentrates more narrowly on person-level website identification and alerts, which may simplify adoption for focused prospecting teams. 6sense focuses on account-based intent and buying-stage signals, while Demandbase offers broader account-based marketing capabilities. Qualified is a closer website-agent comparison, especially for Salesforce-centered teams, but uses custom pricing. Warmly can require coordination among marketing, sales, and revenue operations because its value depends on connecting several workflows. Choose Warmly when a revenue team wants to connect identified intent with chat, CRM routing, automated follow-up, and retargeting across one workflow.
