Choose your processor. Not theirs.
Optix integrates with limited payment providers. Nexudus has regional payment gaps. Calisto connects to 55+ payment gateways across 9 global regions. Collect membership fees, day pass payments, meeting room charges, and event tickets with the processor you already use.
Workspaces need more than reservations
Booking desks and rooms is table stakes. Running a thriving coworking space requires access control, community building, event management, branded WiFi experiences, and marketing that fills empty desks — capabilities Optix and Nexudus were never built for.
Access Control: Not a Third-Party Add-On
Optix and Nexudus rely on third-party integrations for door access, each charging $5–10 per door per month. Calisto Access integrates smart locks natively — no third-party middleware. Members get digital keys in Apple Wallet and Android that activate with their membership and deactivate automatically when their plan expires or gets cancelled. Zone-based access controls restrict after-hours entry, premium areas, and storage rooms by membership tier.
- ✓Digital keys in Apple Wallet and Android
- ✓Automatic activation and deactivation with membership
- ✓Zone-based access by membership tier and time-of-day
- ✓Keys activate and expire automatically with membership status
Community Events: Not Just a Calendar Listing
Nexudus has a basic events calendar. Optix has community announcements. Calisto gives you a full event management engine: ticketed and free community events, member-only networking sessions, workshops with capacity limits, speaker series with seat reservations, and launch parties with POS for food and drinks. Every event builds your community and generates additional revenue.
- ✓Ticketed events with capacity management
- ✓Member-only events gated by membership tier
- ✓Speaker series with seat designer for layouts
- ✓Event POS for food, drinks, and merchandise
Branded WiFi Portal: Your Network, Your Brand
Neither Optix nor Nexudus touches WiFi. Calisto Signal provides a branded captive portal for your workspace WiFi. Members authenticate with their account, guests sign in with email. You capture every visitor's contact information automatically, see real-time occupancy data from connected devices, and deliver a branded first-impression that reinforces your space's identity from the moment someone connects.
- ✓Branded captive portal with your logo and colors
- ✓Member authentication tied to membership status
- ✓Guest WiFi captures contact information automatically
- ✓Real-time occupancy data from connected devices
2% of revenue. Everything included.

Switching questions

Calisto Access integrates with major smart lock brands. If you already have smart locks installed, we connect to them. If you're using traditional key fobs or keycards, we can help you transition to digital keys. Either way, Calisto Access connects to your smart locks natively — members get digital keys that activate and expire automatically with their membership.
Yes. Calisto Navigator gives every member a mobile-first portal where they browse available desks on the floor plan, book rooms by the hour, view and pay invoices, register for community events, message staff, and manage their membership. Digital keys let them tap to enter with their phone.
Yes. Start for free with full access to all 15 products. No credit card required, no time limit, and no feature restrictions. You only pay the 2% revenue share once you begin processing transactions.
Because it makes us partners, not just a vendor. A fixed subscription means your software company gets paid whether you have a record month or an empty lobby. A revenue share means we are financially invested in building tools that actually grow your business. If you have a slow month or a seasonal closure, your bill scales down with you.
