callio.tech ↗EU-hosted, GDPR-compliant
All data sits in EU data centers. No cross-border transfers, no compliance question marks. Your customer data is yours — not the tool's.
Branded booking pages
Add your logo, colors, custom domain, and custom form fields. The booking page feels like a part of your brand — not an external service.
GA4 and Meta tracking
Every booking, every calendar open, every completed checkout fires into your GA4 and Meta Pixel. Lead marketing data lives where you already use it.
Multi-calendar and organizations
Connect multiple calendar sources (Google, Microsoft, iCal) and manage them from one workspace. Create an organization, invite the team, share a common pipeline.
Built-in lead pipeline
Every booking automatically creates a card in a Kanban pipeline. Track the lead from first contact to closed deal — without exporting to a separate CRM.
Stripe payments
Charge for time or service directly in the booking flow. Set price per event type, accept payments to your bank account, auto-issue confirmations.
Free plan with no feature limits
Getting started costs nothing. No credit card, no 14-day trial. You only pay when you need more seats or organization features.
Webhooks and Zapier / Make
Connect Callio to your own backend or to automation tools. Trigger workflows on every booking, reschedule or cancellation.
Who Callio is for
For sales teams that book client meetings. For marketing teams that manage consultations. For customer success teams, recruiters, hairdressers, tutors — for anyone who needs customers to book time.
What sets us apart
Calendly and Cal.com were built for the US market. Callio is built for the European context — with a GDPR-first stance, native tracking into the tools companies actually use here, and a built-in pipeline for teams that don't need a separate CRM.
We built Callio because none of the popular scheduling tools gave European companies what they actually need: control over data, a branded experience for the end customer, and tracking that fits into the marketing stack already in place. Other tools are “just a calendar.” Callio is a calendar, a lead generator and a pipeline in one.
