Five kinds of follow-up. You keep sending the sixth.

The follow-up most founders send

You met an investor on Tuesday. The meeting felt good. By the following Tuesday you have heard nothing, so you open your email and write some version of this:

Hi Sarah, just wanted to follow up on our conversation last week and see if you had any questions. Happy to jump on another call. Looking forward to hearing from you!

You read it back, decide it sounds fine, and send it. It is not fine. It asks the investor to do the work of figuring out why they should re-engage. It adds no new information. It restarts the conversation from zero instead of advancing it from where it stopped. And it signals that you are tracking time, not progress.

The investor reads it in two seconds, thinks "nothing new here," and archives it. Now you have spent one of your limited touchpoints making yourself look like every other founder in their inbox.

The problem is not that you followed up. The problem is that you sent a follow-up with no job. Every email you send into a live round should do one specific thing that the conversation needs next. There are only five things it can usefully do. If your draft does not match one of the five, you are writing the sixth.

The five follow-up types

A useful follow-up is defined by its trigger, not by its timing. Before you write a word, name which of these five jobs the conversation needs.

1. Proof update. Something measurable changed since you last spoke. You shipped, signed, grew, or hit a number. The follow-up exists to put new evidence in front of the investor that strengthens the exact thing they were skeptical about. Trigger: a real metric or milestone moved.

2. Objection answer. In the meeting they raised a specific doubt, and you either did not have the answer or gave a weak one. The follow-up exists to close that open loop with a real answer. Trigger: an unresolved question is sitting on the table.

3. Intro loop. The investor passed, went quiet, or is not the right fit, but they know people who are. The follow-up exists to convert one dead-end relationship into two or three live ones. Trigger: this particular path is closing but the person still has reach.

4. Timeline prompt. Your round has real structure: a lead is circling, a date is set, allocation is filling. The follow-up exists to give the investor a true reason that waiting has a cost. Trigger: external timing in the round genuinely changed.

5. Diligence response. They asked for materials, data, references, or a model. The follow-up exists to deliver exactly what was requested, fast and complete, and to make the next step obvious. Trigger: they asked you for something concrete.

Notice what every one of these has that "just checking in" does not: a trigger that comes from the investor's side of the conversation. You are not following up because a week passed. You are following up because something happened that changes what they should do next.

The before and after

Here is the same dead conversation, rescued by matching the type to what happened.

The investor's last words in the meeting were: "The story is interesting, but I'd want to see whether the early usage holds up past the first month."

The sixth type (what most founders send):

Hi Sarah, following up on last week. Any thoughts? Would love to find time to continue the conversation. Let me know!

The objection answer (what the conversation needed):

Hi Sarah, you flagged month-two retention as the thing you'd want to see hold. I pulled the cohort data: of the 40 teams that activated in April, 33 were still active in May (82%), and weekly active sessions per team went up, not down. Chart attached. That was the open question from our call, so I wanted to close it with real numbers rather than a promise. If it's useful, I can walk through how we drove the month-two number on a 15-minute call this week.

The second email does the investor's work for them. It reminds them of their own objection, answers it with evidence, and offers a low-friction next step. It is longer, and that is fine, because every extra sentence carries new information. The first email is shorter only because it says nothing.

The artifact: follow-up selection tree

Run any open conversation through this before you draft. Start at the top and take the first branch that is true.

Did they ask you for something specific (data, refs, model, deck access)?
   YES → DILIGENCE RESPONSE. Send exactly what was asked, complete, within 24h.
   NO  ↓

Is there an unresolved objection or question from the meeting?
   YES → OBJECTION ANSWER. Name their doubt, answer with evidence, offer next step.
   NO  ↓

Did a real metric / milestone move since you last spoke?
   YES → PROOF UPDATE. Lead with the number tied to their thesis or skepticism.
   NO  ↓

Did the round's external timing genuinely change (lead, date, allocation)?
   YES → TIMELINE PROMPT. State the true change and the cost of waiting.
   NO  ↓

Is this path closing, but the person still has reach into your space?
   YES → INTRO LOOP. Ask for 2-3 specific intros, make forwarding easy.
   NO  ↓

None of the above is true today.
   → DO NOT SEND YET. You have no job for this email.
     Go create a trigger (ship, close, line up the lead) or wait until one exists.

That last branch is the one founders skip. If nothing has changed and they did not ask for anything, the honest answer is that there is no follow-up to send right now. Manufacturing one is how you train an investor to ignore you.

The template bank

Five jobs, five drafts. Fill the brackets from your actual notes.

Proof update

Subject: Update on [the thing you were skeptical about]

Hi [name], when we spoke you wanted to see [specific concern]. Since then [concrete change with a number]. [One line on why it matters for the thesis you discussed.] Happy to share the underlying data if useful.

Objection answer

Subject: The [topic] question from our call

Hi [name], you raised [their exact objection]. I didn't have a clean answer in the room, so I dug in: [evidence / reasoning]. [One sentence of what it means.] If it's worth a deeper look, I can walk through it in 15 minutes this week.

Intro loop

Subject: Quick ask

Hi [name], sounds like this isn't the right fit for [fund] right now, and I appreciate the straight read. You know this space better than almost anyone. Are there 2-3 people you'd point a founder like me toward at [stage/thesis]? Happy to send a forwardable blurb so it's one click for you.

Timeline prompt

Subject: Timing on the round

Hi [name], wanted to give you a real heads-up: [true change, e.g. "we have a lead circling and are aiming to close the round by [date]"]. I'd rather you have the full picture than feel rushed. If you want to take a closer look before [date], let's find time this week.

Diligence response

Subject: Materials you asked for

Hi [name], here's everything from our call: [list, each item linked]. [If anything is pending: "The one open item is X, you'll have it by [date]."] Let me know what's most useful to dig into and I'll prioritize it.

Print this. The discipline is not in the wording. It is in refusing to send anything that does not map to one of these five.

Where the triggers live

The selection tree only works if you can see the triggers. In practice they are scattered: the objection is buried in a meeting note from three weeks ago, the diligence request is in an email thread you have stopped opening, the proof update is a metric that just moved in a dashboard, and the intro opportunity is a "this isn't for us, but…" line you skimmed past.

This is the part of fundraising that breaks under load. By the time you have 25 live conversations, no founder can hold each investor's last objection, open ask, and next logical move in their head. So the follow-ups regress to the mean, and the mean is "just checking in."

RoundOS is built to keep that context in one place. It pulls your meeting notes, email threads, and investor list together, tracks what each investor last said and asked, flags the threads that have gone stale, and surfaces the next move per conversation. So when you sit down to write, you are not staring at a blank inbox guessing who to nudge. You are looking at a queue that already knows which of the five follow-ups each conversation needs, with the trigger attached. The writing is the easy part once the type is decided for you.
