CallMerlin
Breda, Netherlands
What it is
CallMerlin is an AI assistant for business systems, available through phone, chat, a widget, desktop, mobile, Slack and Teams. It supports workflows that span multiple systems, respond to triggers and include an analysis step with auto-inject. Reads can take place immediately; writes, emails and payment files require approval unless direct execution is enabled. The integrations page lists 96 native deep integrations and more than 900 options through managed connectors, with examples including HubSpot, Salesforce, Slack, Moneybird, Microsoft 365, Gmail, Stripe, Shopify and Zoom. The company says each teammate has an individual PIN and permissions are enforced server-side. Its Trust Center describes AES-256-GCM credential encryption, TLS protection in transit, and PIN plus 2FA access. By default, call transcripts and AI summaries are kept for up to 90 days, while audio is not retained. Plans start at €55/mo (annual), with a 7-day trial and no free plan. Android is in closed alpha; the iOS App Store listing is coming soon.
