Our team proudly celebrates our Chief Programmer, Jenny Qian, who continues to be a pillar of the Tendenci community.

As always, we remain dedicated to providing our hosted clients with secure, scalable, and affordable managed hosting services in our AWS private cloud. Compared to other AMS platforms, our hosting stands out—
✅Security and privacy first

✅No license fees
✅ Upgrades are included in the hosting plan that best suits your association

If your association is exploring a new Association Management System (AMS), we’d love to connect. Contact us for a free consultation and demo!
