Hello, from the world's most beautiful calendar.
*No credit card required
TLDR: Vimcal is the best calendar app for founders. It started as a calendar built by founders, for founders, and years later, founders are still the largest group of people who use it.
It's built for what a founder's week actually looks like: dozens of meetings with investors, customers, and candidates, across time zones, with little time in between.
Vimcal came out of my own fundraise.
After YC Demo Day, we suddenly had to schedule 30+ investor meetings a week. Every one of them involved emails back and forth, time zone math, and checking who on our side was free.
Booking links felt too impersonal to send to investors we were trying to win over. So we did it by hand, and it ate our days.
We built Vimcal to fix that for ourselves. Our only test for a feature was simple: do we like it, and would we use it?
We weren't the only ones with the problem. More than 10,000 people joined our original waitlist, and over 40% of them were founders.
Today Vimcal is used by executives, EAs, salespeople, and VCs, but founders are still our largest group of users.
A founder's calendar is three jobs stacked on top of each other: selling to customers, raising money, and hiring.
Almost all of it involves people outside your company. That's the hard part of scheduling, and it's exactly what most calendar apps aren't built for.
Calendar apps tend to fall into two camps. Some are built for meeting-heavy work. Others are built to protect your focus time and plan your tasks.
Most founders, at least once the company has customers or a round to raise, live in the first camp.
The fastest way to find out whether a calendar works for you is to run a fundraise on it.
When you're trying to land 30 meetings in two weeks, the time it takes to reply to an investor matters. An intro that sits for a day goes cold.
With Slots in Vimcal, you pick open times on your calendar and they're turned into text in the investor's time zone, ready to paste into your reply. It takes seconds.
It feels like a personal email because it is one. You picked specific times for a specific person.
Not every meeting deserves your best hours. A lead investor's partner meeting and a first call with a recruiter shouldn't compete for the same Tuesday morning.
Slots lets you choose exactly which times to offer each person. Your best hours go to the people who matter most right now, and lower-priority meetings get what's left.
It works across meeting types too. A founder's week mixes fundraising, hiring, customer calls, and things like a check-in with your lawyer.
You can offer investors your mornings, give candidates your afternoons, and push the lawyer to Friday. Everyone gets a short, personal list of times, and you stay in control of your week.
A single booking link shows everyone the same open times, so whoever clicks first gets your best slot.
Ask most founders how they spend their time and they'll say customers, product, and hiring. Look at their calendar and it's often internal meetings.
Vimcal can tag meetings automatically, for example investors, customers, candidates, and internal, based on who's in the meeting or what it's called.
The weekly metrics then show how much time went where, including internal vs. external time and who you met with most. It's an honest mirror.
It also shows your Swiss Cheese Time: the gaps between meetings that are too short to do real work in.
For a founder, those gaps are where the thinking and building time disappears. Seeing them is the first step to protecting a few real blocks.
Founders don't have time to wait on software. Vimcal follows the 100ms rule: every action is meant to feel instant, and nearly everything has a keyboard shortcut.
You can type an event in plain English, like "Coffee with Sarah Friday 3pm at Blue Bottle," and it's on your calendar.
On iPhone, you can check when a cofounder or teammate is free while walking out of a pitch, and schedule by voice.
Most founders have more than one calendar: the company account, a personal account, maybe an advisor role or a side project.
Vimcal shows them together and merges duplicate events, so the same meeting doesn't show up three times.
If you're a solo technical founder writing code most of the day, with five meetings a week, you probably don't need a calendar built for meetings.
A planner like Motion or Reclaim, which schedules your tasks and protects focus time, may serve you better.
That usually changes the moment you start selling or raising.
Vimcal. It was originally built by founders for fundraising and is designed for meeting-heavy weeks with lots of outside scheduling.
Reply to each intro with a few specific times in the investor's time zone. It's faster and more personal than a booking link. Vimcal turns open times on your calendar into that text in seconds.
Many founders avoid it, because it can feel impersonal when you're the one asking for time. Sending specific times in a short email tends to land better.
Tag meetings by type, such as investors, customers, candidates, and internal, then review the totals weekly. Vimcal does the tagging and the weekly metrics automatically.
Vimcal's iOS app is free. The desktop app is paid, with a free trial.
If your week is full of investors, customers, and candidates, start a free Vimcal trial. No credit card required.
