Includes native integrations with HubSpot, Salesforce, and 500+ other tools via API and MCP. - **[lemwarm]**: Automated email warmup and deliverability booster, included with every lemlist seat. - **[Claap]**: Acquired by lemlist; a meeting intelligence product that records, transcribes, and analyzes sales calls – now integrated into the lemlist ecosystem. ## Market Standing - **Valuation/Market Cap**: Not disclosed - **Key Metric**: Total funding of $30M (Venture Round, November 2021); public goal of $150M ARR by 2030. - **Notable Investors/Partners**: Lead investor in the $30M round is not publicly named.
