Your alumni want to help. Your students can't find them.
Arcus puts your students and alumni in one directory, on a domain that belongs to your school or organization. Counselors see every mentorship connection. Nothing in the feed comes from outside.
Your community deserves a home of its own, not a spreadsheet and a newsletter.
Most schools and organizations keep their alumni in a database, their students in a portal, and the connection between them in somebody's inbox. The people who could help each other most never actually meet.
Arcus replaces that with one private site your whole community lives in: a directory that stays current because people keep their own profiles, a feed your school or organization runs, events people actually RSVP to, and mentorship that happens on the record instead of around it.
And because it's yours, it lives at your domain and carries your school or organization's name. Arcus stays off the door.

One site your whole community actually uses.
Students find their people, alumni find each other, and your office finally has the roster it always wanted. Everything below is the real product, shown with people from our synthetic demo community. Your school or organization starts with its own roster imported on day one.
Mentorship with a counselor in the loop
A student finds an alum through safe fields (class year, field, city) and asks for an introduction. The request goes to a counselor first, every time, by design. Approved intros open monitored conversations the school or organization can stand behind.

A directory that stays alive
Every member of your school or organization on one list and one map, keeping their own profiles current. And when your office needs someone, the search speaks plain English: the database does the finding.

Giving that goes straight to your school or organization
Campaigns run through Stripe and settle to your school or organization's own account. Arcus never touches the money, and your office watches it land in real time.

Know who to ask, before you ask
Most advancement offices are guessing. A reunion year, a first gift five years ago, a mentor hour given last spring — the signals are already in your data, and nobody has time to read them.
Arcus ranks your alumni by how likely they are to give, and says why in a sentence. Your office spends its calls on the fifty people worth calling instead of the whole list, which is the difference between a campaign that hits its number and one that doesn't.
The ranking runs on your school's own data and never leaves it. Every suggestion shows its reasoning, and a person decides who to contact — the model does not send anything.

Built for the office that runs it.
Advancement teams are small, often one or two people. Arcus is built to give them leverage, not another queue to babysit.
Roster import, done for you
Send us what you have: spreadsheets, exports, the works. We bring in alumni and students, and invitations go out under your school or organization's name.
Profiles that keep themselves current
Only the owner can edit a profile, so members maintain their own records, and your database stops aging the moment people log in.
One moderation queue
Member reports and flagged messages land in a single queue with the context to act: review, clear, or remove in one sitting.
An audit log you can stand behind
Admin actions, data exports, and every adult–student interaction are recorded immutably. When someone asks, you have the answer.
AI where it earns its place. Nowhere else.
Arcus is built on the working half of AI — the part that saves a small office real hours — and it stays in its lane: the model drafts, ranks, and explains; people decide.
Search that speaks plain English
Type “a lawyer in New York who could talk to a senior about law school” and the right people come back. AI translates the request; your directory does the finding. Nobody learns the filter syntax, because there isn't one.
Introductions that come with a reason
When a student looks for a mentor, matching runs across your whole community — and every suggestion says why in a sentence, like the shared industry or the city in common. A counselor reads the reason, not a score.
Profiles that fill themselves in
A member pastes their résumé or LinkedIn and Arcus drafts the profile — role, industry, skills, a short bio in their own words. They fix what's wrong and save. Thirty seconds instead of a blank form, which is the difference between a directory that fills and one that doesn't.
The rules it runs under
Your community's data never trains anyone's model — ours or a provider's — and runs under zero-retention terms: nothing is kept after an answer is produced. Each school's data stays its own, and the model only ever sees the minimum a task needs. AI never messages anyone, approves anything, or acts on its own.
From roster import to first introduction. Here's how.
What getting started looks like, with us doing the heavy lifting for our first schools and organizations.
1
We set up your site
Your own domain or a subdomain, your logo on the door, and the modules you want turned on.
2
Your roster comes in
We import alumni and students from whatever you have today, and invitations go out under your school or organization's name.
3
Members claim their profiles
Everyone keeps their own page current. Only the owner can edit it — not us, not even your admins.
4
Students ask, counselors approve
A student finds an alum through safe fields and requests an introduction. A counselor reviews it before it ever reaches the alum.
5
The community runs
The feed fills, events get RSVPs, gifts settle to your school or organization's account, and your office finally sees all of it in one place.
Our students are minors. The product is built like it.
The safeguarding rules aren't a policy page — they're enforced at the data layer, for every school and organization, and no configuration can loosen them.
Rule 1
Adults never make first contact
An adult can never start a conversation with a student. Ever, by any path. It's blocked in the database, not just the interface.
Rule 2
A counselor approves every introduction
Students reach alumni only through mentorship requests a counselor or admin has reviewed and approved first.
Rule 3
Every conversation is on the record
Adult–student conversations are monitored and immutably logged for the school or organization. Nothing happens off the books.
In July 2026, Charlie was volunteering with a network of school admin teams throughout Cleveland. Across all the schools, there was one common thread — their lack of funding largely came from an inability to reach alumni, and when they were reached, to keep them engaged. We started Arcus because the most valuable thing a community owns — the people who have been through it — mostly sits in a spreadsheet.
To keep alumni engaged, we built Arcus with connection at the forefront. An alum can finally reconnect with their class in a chat group, and a student interested in medicine can find those who went to the same med schools they're looking at.
We're starting deliberately: one pilot community at a time, built properly, with safeguarding enforced in the database rather than promised in a policy. If that sounds like your school or organization, we'd like to talk.
