Now in private beta

Your calendar knows
when you're free.
It has no idea how you think.

Calenderly is a scheduling agent you train in plain English. Tell it your preferences once. It enforces them — automatically, for every person who books you. The person booking sees nothing different. The intelligence is invisible.

1,200+ founders in beta
3 slots not 30
Zero AI at booking time

You have a philosophy about your calendar.
Your scheduling tool has no idea.

You know mornings should be for deep work. You know investor calls should be batched on specific days. You know that showing 15 open slots makes you look like you have nothing going on. You enforce these opinions manually — blocking time, declining requests, rearranging your week every Sunday night. And by Wednesday, it's all fallen apart.

📅

The Sunday Night Ritual

Every week you block "deep work" and "no meetings" on your calendar. By Tuesday, someone’s booked over them. You let it slide because saying no feels worse than losing your morning.

🌍

The Timezone Lottery

Your SF investor and your London advisor see completely different slots. Same link, same day — different options. There’s an invisible advantage to being in the "right" timezone, and you can’t control it.

📉

The Availability Signal

You send your booking link with 15 open slots showing. The investor sees a founder with nothing going on. During a fundraise, that signal costs you leverage you can’t get back.

🔗

The Multi-Link Mess

During your last fundraise you had 3 booking links — one per timezone — with manually curated slots. When someone booked, you had to rotate the next slot in. 30 minutes a week managing the tool that’s supposed to save you time.

The Blind Booking

"Quick 15 min chat?" No agenda. No context. No idea what it’s about until you’re on the call. 30% of your meetings are brain-picks from people who never articulated what they actually need.

🧩

The Scattered Day

Four meetings today — at 9am, 11:30am, 2pm, and 4:30pm. Four context switches. Four blocks of dead time in between too short to do real work. Your tool put them there because they were "available."

Every scheduling tool on the market does the same thing: it checks when you're free, then shows every open slot to whoever has your link.

That's not scheduling intelligence. That's a filter with a pretty UI.

The gap between “when am I free” and “when should I actually take this call” is enormous. That gap is filled by you — manually, imperfectly, every single week.

What if your calendar could close that gap for you?

Train your agent in plain English.
It runs on autopilot.

Type what you want. Your scheduling agent compiles it into deterministic rules. It shows you exactly what it understood. You confirm. From that moment, every slot it shows to every invitee reflects your philosophy.

you → Keep mornings free for deep work
you → Batch investor calls on Tuesdays and Thursdays
you → No meetings on days I have board prep
you → VIPs get my mornings. Everyone else, afternoons.
you → Stack calls together — I hate scattered meetings

Zero AI at booking time. Your instructions compile once. At runtime, same input → same slots. No latency. No hallucination. No “the AI booked you at 6am.” Deterministic. Predictable. You see every rule before it runs.
Natural language

Say it like you’d tell an EA

No toggles to learn. No docs to read. If you can say "keep Fridays light," your agent knows what to do. It compiles your plain English into rules and shows you exactly what it understood.

Deterministic

No AI at runtime. Ever.

The LLM is the compiler, not the runtime. Once your rules are set, they execute the same way every time. Your invitees never wait for AI. There’s no "oops."

Invisible

Invitees see nothing different

A clean calendar. A few time slots. Pick one. Done. No chatbot, no AI interface, no "tell our assistant what you need." The revolution is behind the curtain.

Compounding

It gets smarter as you teach it

Add rules over time. Layer preferences. Your first week, it protects your mornings. By month three, it’s running your entire scheduling philosophy on autopilot.

Stop showing everyone
how available you are.

Every scheduling tool maximizes availability. Calenderly optimizes for strategic unavailability. Show 3 slots, not 15. Same 3 for everyone — SF, NYC, London, Singapore. When one gets booked, the next-best slot unlocks automatically.

15 open slots. The invitee scrolls lazily, maybe picks one, maybe comes back later. No urgency. The signal: “this founder has nothing going on.”

3 curated slots. Your agent picked the best times. Same 3 everywhere in the world. Book one — the next-best slot unlocks. It fills forward like there's a line.

“I went from 15 visible slots to 3. Booking rate went up. No-shows went down. People started sending agendas before the call.”

— Founder, Series A, 22 investor meetings/week

Know the “why” before
you give the “when.”

Other scheduling tools ask when you're free. Calenderly asks your invitee why they want to meet — before they see a single time slot. You get context. They get accountability. Low-effort “quick brain-picks” quietly disappear.

Step 1

Invitee answers “why”

Before seeing any slots, they describe what the meeting is about and what outcome they're looking for.

Looking for a 30-min intro + term sheet overview
Step 2

Your agent routes it

Based on the intent, your agent decides which tier of slots to show — VIP mornings, default afternoons, or tighter constraints for cold inbounds.

→ Tier: High-stakes · Morning slots · 60 min
Step 3

Invitee picks a slot

They see the curated slots your agent selected. Pick one. Done. The intelligence was invisible — they just saw a clean, simple calendar.

A fundraising call and a cold inbound
are not the same meeting.

Your agent runs different rules for different meeting types. High-stakes meetings get the best slots automatically. Low-priority requests get tighter constraints. It's not about blocking people out — it's about routing them correctly.

Every mode has its own rules, constraints, and slot logic. Switch between them or run them simultaneously — your agent handles the overlap. One link, multiple meeting types, zero conflicts.

Settings are for parameters.
