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.
