Calculator · Founders

Customers, candidates, investors and your co-founder all land in the same queue, and there's no EA yet to hand any of it to. Start from a founder's week below, then move every slider until it matches yours.

Starting point: Founders

A starting point rather than a measurement of any real founder's time: an inbox that runs on customers, candidates and investors, a role that regularly spills into the weekend, and a recurring investor update. Every slider below is yours to move. See [the numbers](https://beemy.co/the-numbers) for how we picked it.

## Where these numbers come from — no black box.

### The time

Hours/day × working days = hours/week on email. Add recurring reports and newsletter/news reading, then multiply by 52 weeks. No hidden multipliers.

### The $45/hr starting point

A placeholder for the value of your time, yours to adjust. Move the slider to match your own rate, and the rest of the maths follows it.

### The 60% reclaim

Triage (read, classify, decide, draft a first pass) is repetitive and context-dependent rather than judgement-heavy, and it's most of the time in most inboxes we've looked at early in beta. The remaining share is judgement calls that still come back to you. This is our own working assumption rather than a measured industry figure, and we haven't yet published usage data from our own beta to replace it with a real one.

### The 20% review share

We have not measured this figure. Every draft still waits for a one-tap review until its category earns level 2, and only four categories (meeting_confirmation, scheduling_ack, simple_ack, routing_filing) can ever reach auto-send — see /what-you-still-do for the full case. Twenty percent is our own guess at what that ongoing review still costs you, not a study of it. Move the slider to your own number; this default exists to be replaced. See [what you still do](https://beemy.co/what-you-still-do) for the full case.

**Sources & assumptions:** the 117-emails-a-day figure above is Microsoft WorkLab's own 2025 telemetry; the 60% reclaim rate, the 20% review share we subtract back out, and every preset's starting numbers are our own assumptions, not citations. Every number this calculator uses, sourced or assumed, is on [/the-numbers](https://beemy.co/the-numbers).

Where the hours actually go

## A founder's week keeps producing the same four jobs, split between the inbox and the admin pile behind it.

### The pricing question, again

Pricing, the security review and the integration list come from a new contact every week. The answer already exists in last month's thread, so writing it twice wastes time. A saved answer, lightly edited, would take a fraction of that time.

### The candidate who's gone quiet

A promising candidate stops replying after the second interview, and chasing them feels awkward without a script. A short, well-timed note brings most of them back before the role goes cold. Sending it takes almost no time, and it decides between a filled role and a restarted search.

### The industry newsletters nobody has time for

A dozen newsletters and a few subreddits promise to keep a founder ahead of the market. Reading all of them properly would eat a whole morning, so most go unread instead. A short, curated version covers the same ground and leaves the morning alone.

### The investor update, rebuilt from scratch

The numbers for the update already exist somewhere in a spreadsheet before anyone starts writing. Pulling them together into one document each month is the part that actually eats the time. Once that first pull is done, the rest of the update is just a read-through.
