We build software that gives humans their time back.
Calendeur is an engineering-first scheduling and voice AI platform designed for high-velocity teams who refuse to let administrative friction throttle their growth.

Why we created Calendeur.
In 2024, our founders noticed a glaring paradox: while AI made software development and generative media instantaneous, business scheduling remained stuck in 2012. People were still exchanging ten emails to confirm a 20-minute Zoom call.
Meanwhile, businesses were paying exorbitant fees to legacy vendors for basic calendar links filled with aggressive third-party branding. We set out to build the definitive alternative: an autonomous, beautifully designed, all-in-one system combining voice reception, conflict management, e-signatures, and custom domain white-labeling.
Our Commitment to You
- Zero Host Penalties: We believe in simple, transparent pricing with unlimited booking links.
- Direct Engineering Support: Every customer speaks directly with technical engineers who write the code.
- Continuously Evolving: Weekly shipping cadence with transparent public changelogs and roadmap voting.
Guiding Principles
The foundational values driving every engineering decision we make.
Autonomous Intelligence First
Scheduling should not require humans to play email tag. AI should answer phone calls, verify timezones, and confirm reservations seamlessly.
Unyielding Privacy & Isolation
Client calendar data is sacred. We never train public foundation models on your meeting transcripts or customer contact records.
Apple-Grade Tactile Design
Software should feel alive, responsive, and exquisitely crafted. Every button, shadow, and interaction is engineered with purpose.
True White-Label Sovereignty
Your brand belongs to you. We empower businesses to deliver world-class client portals without vendor watermarks.
