Enterprise ERP, built the way software should be built today.
Tier Lotus designs and engineers modern ERP platforms for the institutions that keep things running — modular, isolated, and secure by design. We replace the decade-old systems at the core of an organization with software that's fast, dependable, and a pleasure to use.
A platform, not just an app.
Every Tier Lotus product is built on the same foundation and the same principles — so it scales, stays secure, and gets out of the way of the people who use it all day.
Modular by design
A modular monolith: the velocity and reliability of one codebase, organized around clean business modules — with the seams to split out a service the day one genuinely needs it.
How we build →Your data, fully isolated
A dedicated database for every customer — the strongest isolation model there is. Simpler compliance, no noisy neighbors, and clean per-customer backup and restore.
The architecture →Secure by default
Role-based permissions, a complete audit trail, and secrets held in Key Vault — never bolted on after the fact. Security is the foundation, not an upsell.
Our approach →Cloud-native, always current
Built for Microsoft Azure from day one: elastic, observable, and continuously deployed. No upgrade projects that take a year, no on-prem servers to babysit.
See it shipping →"The economics of building excellent enterprise software have changed. A small, focused team can now take on the systems that used to require an army — and build them the way the institutions actually need them built." — Portia Altimus, Founder & Chief Architect
Aedium — the platform, proven.
Our first product is a complete ERP and student information system for community and technical colleges — a drop-in replacement for Banner, Colleague, and Jenzabar. It's the Tier Lotus platform, running in the wild.
Admissions through commencement. Finance through financial aid.
SIS, scheduling, the bursar's general ledger, financial aid, IPEDS reporting, customizable dashboards, and a connector framework — one cloud-native platform per institution.
Replacing a legacy system, or building something new?
Whether you're a college evaluating a modern SIS or an institution with a problem that doesn't fit off-the-shelf software, we'd like to hear about it.
