What an AI Chief of Staff actually does: a Tuesday morning

What an AI Chief of Staff actually does: a Tuesday morning

We rolled out new homepage copy this week. It positions Marvin as your AI Chief of Staff. A fair question, one we got within hours of shipping, is: what does that actually mean? What does a day with Marvin look like?

So here's a Tuesday. Specifically, here's the first ninety minutes of one Tuesday in an investor's inbox, with the parts that involve Marvin annotated.

7:03 AM. The daily portfolio brief lands. The investor has fifteen holdings; the brief surfaces material news on four of them. Two earnings beats, one regulatory development, one acquisition rumor. Each bullet cites the original source. Reading time: under two minutes. The investor flags the regulatory development for follow-up and moves on.

7:12 AM. A founder she met at a dinner forwarded their seed deck overnight. She forwards the email straight to Marvin with three words:

To: marvin@ccmarvin.com

Hi Marvin,

memo on this

By the time her coffee finishes, the response is in her inbox: a structured analysis of the deck. What's interesting, what's missing, follow-up questions for the founder, a brief read on comparable round sizes in the space. She skims, edits two paragraphs, and forwards her partner a clean memo with her own take added.

7:34 AM. She's reading a Bloomberg article that references an X thread. She copies the thread URL, emails it to Marvin: "what's actually being said here?" Marvin reads the post (noting it can't see replies without their URLs) and sends back the actual content. No screenshots, no hallucinated context. She has what she needs in 30 seconds.

7:51 AM. Her assistant emailed her a calendar invite for a 1:1 with a portfolio CEO next week. She forwards it: "add to my calendar and pull the CEO's last update so I can prep." She gets back both: Google Calendar and iCal links, plus a summary of the CEO's last quarterly update.

8:09 AM. She wants more depth on the regulatory item from the 7 AM brief. She replies to that thread: "deep research report on the EU AI Act's implications for companies like XYZ in our portfolio." Marvin acknowledges and she gets back to her morning. Around 8:35, the full report lands: a few thousand words with citations, ready to share.

8:42 AM. A junior associate cc'd her on a deal thread, six replies deep. She adds Marvin to the cc: "summarize this thread and tell me if I need to weigh in." Marvin summarizes the key disagreement and flags the one question where her input would unblock the rest. She replies with two sentences. Done.

8:50 AM. The acquisition rumor from the morning brief got more interesting overnight. She replies: "for tomorrow's brief, lead with [Company], and go deeper if there are new developments." Marvin updates the recurring task.

That's roughly ninety minutes. Marvin handled eight discrete asks. Her input across all eight was maybe four minutes: a forward, a couple of replies. The work happened in her inbox, asynchronously, while she did the things only she can do.

What's actually going on

What makes this work is not that Marvin is "smart." Lots of things are smart. It's that the interface is email: the inbox she's already in. No new app, no tab to manage, no place to context-switch to.

That's the entire bet. Email is where knowledge work ends up anyway. We made an AI assistant that lives there and emails back like a colleague would, using the verbs you already use. You don't ask Marvin to "do a search," you forward him a thread. You don't paste a deck into a chatbot, you forward the email. You don't say "use the calendar tool," you forward the invite. The product's surface is your existing workflow.

The four jobs we see most

Across all the Tuesday-morning patterns we watch, four recurring uses dominate:

  1. Daily intelligence briefs: portfolio, topical, custom. Set once, arrive every weekday morning, tunable by reply.
  2. Document analysis: forward a deck, a PDF, a data room link, a 10-K. Get back analysis in minutes.
  3. Deep research: multi-hour synthesis on a question, delivered as a structured memo.
  4. Thread coordination: cc Marvin on a thread to get a summary, a recommended response, or an action plan.

If you do any of those things repeatedly today (paying for newsletters, opening ChatGPT to analyze a doc, copy-pasting context to ask follow-ups), Marvin is probably the missing piece of your inbox.

How to start

Email marvin@ccmarvin.com from your normal inbox. Forward him something, ask him a question, or just tell him what you want him to set up.

That's the entire onboarding. There's no app to install.
