you can finally afford.

For people who run things
You shouldn’t need a 6·a.m. wake-up just to remember what you owe people.
Most days you’re holding the whole picture in your head. The reply you owe Sarah. The follow-up from Tuesday’s call. The Stripe invoice you keep meaning to check. The intro you promised back in March.
Maraithon is the assistant who quietly remembers all of it — and gently tells you when it’s your turn to move.
What you get
One calm screen. The whole picture.
- Today
- The five things that actually need you, picked from your inbox, calendar, and open threads. Open the app, see the day. Close the app, get on with it.
- Open Work
- Capture in a word. Maraithon fills in the rest — who it’s for, when it’s due, where it came from. Waiting on someone? It nudges them so you don’t have to.
- People
- Every conversation, in one place. Last time you talked. What you promised them. What they promised you. The intro you owe. The birthday you almost missed.
- Chat
- Tell it what you need. “Draft a reply to Mark.” “Remind me to ask Yitong about the redesign.” “Who haven’t I talked to in a month?” It just… handles it.
Before & after
The same day. Different week.
Without Maraithon
- · Three apps open, none of them right.
- · “I’ll get back to you next week” emails piling up.
- · You forgot to reply to your investor again.
- · You meant to introduce them six weeks ago.
- · Sunday night feels like a homework deadline.
With Maraithon
- · One screen. Five things. Done by lunch.
- · A reply is drafted; you tap send.
- · You knew about the investor before they nudged you.
- · The intro went out on Tuesday.
- · Sunday night feels like Sunday night.
Mac companion
Your assistant sees what you see.
Install the Mac companion and Maraithon quietly catches up on everything that lives on your laptop — iMessage, Notes, voice memos, calendar invites, Reminders. It connects the dots between a Slack message at 9, a Notes outline at 11, and an email at 3.
You stay in control. Pause it whenever you want. Delete what you want gone.
- iMessage & SMS. The thread you forgot you were in.
- Apple Notes. The thought you jotted at 2 a.m.
- Voice memos. The walk you talked through last week.
- Calendar. The meeting you forgot to prep for.
- Reminders. The things you told Siri so you wouldn’t forget.
Stored privately in your account. Never shared. Never sold. Deleted when you say so.
Everywhere you are
One assistant. iPhone & Mac.
The iPhone app is where you check in. The Mac companion runs quietly in the background. The two stay in sync without you thinking about it.
