Client Atrium grew up inside a working agency.
I’m Ryan. I run RMH Websites, a small web agency, and Client Atrium started as the internal tool I built for my own clients.
Here is what kept happening. I would set up a client portal, one of the ones you have seen advertised, and my clients would not use it. Not out of stubbornness; they are dentists and lawyers and bakery owners with a business to run, and one more login was one login too many. They kept replying to my emails instead, which meant the portal showed a tidy, empty workspace while the real project lived in my inbox. Meanwhile the portal billed me for every client I added to it. I was paying more each month for software my clients used less.
So I built around the one fact I could not change: clients live in their inbox. In Client Atrium, replying to a normal email IS using the portal. The reply lands in the right thread, the attachment files itself, and the waiting-on-client status clears on its own. My clients never changed their behavior, and I stopped losing track of who owed me what.
Then came the parts an agency needs around that: contracts they could sign without me paying for a separate signature tool, a list of everything I was waiting on across every client, and projects with stages a business owner understands. My agency has run on it every day since. The product shown on this site is the one my agency runs on; the client names are invented.
Now I’m opening it to other agencies. The trial is self-serve, so you can start tonight, and when you decide to move your whole client book over, I help with the migration myself, one agency at a time. I will not pretend there is a big team behind this. There is me, an agency that depends on this software working, and a product that gets better every week because I feel its rough edges before you do.
If any of this sounds like your agency, try it with one client and see. And if you have a question, email me. I answer the hello@ inbox myself.

What the product believes.
Clients should not need accounts.
Email is the front door, not a workaround. Anything that requires your client to change their behavior will eventually fail.
Price the team, not the client list.
Your growth is your reward, not our revenue. Unlimited clients on every plan, permanently.
Archive, never delete.
Client history is too valuable to lose to a misclick. Destructive actions archive, and real deletion is deliberate.
AI is opt-in, per switch.
Helpers can save real time, and they ship off. You choose each one, and drafts wait for your edit.
Leaving must be easy.
Full export in readable formats and source escrow in the terms. Software you cannot leave is software you cannot trust.
