Why founders switch

Your calendar doesn't know what matters. Arrangr does.

Every week, founders lose their best hours to meetings that shouldn't have been booked. Here's what that actually costs you.

Fundraising

A warm intro to a Tier 1 VC dies in a scheduling thread.

You got the intro. You sent availability. Three days of back-and-forth later, they've gone cold — or worse, booked a competitor. The meeting never had a chance.

Arrangr sends a personalized 1:1 invite in seconds. Investors book directly — no thread, no friction, 94% close rate.

Hiring

Your best candidate accepts another offer while you're coordinating interviews.

You're running a five-person interview loop across two time zones. The candidate is fielding three other offers. Every day of scheduling delay is a day they're closer to saying yes to someone else.

Arrangr syncs your whole interview panel in one link. Candidates see real availability and book instantly — no coordinator needed.

Deep Work

A low-priority internal sync just ate your only 2-hour focus block.

Someone booked a "quick check-in" at 10am — right in the middle of the only uninterrupted window you had all week. Now your most important work gets pushed to whenever that's left.

Priority Mode protects your best hours. High-stakes meetings get the prime slots — low-priority holds get bumped automatically.

How it works

Two features. One calendar that finally works for you.

Most tools add features. Arrangr adds intelligence. Priority Mode and Ari are the reason founders don't go back.

Priority Mode

Your calendar, ranked by what matters most.

Priority Mode is the core of Arrangr's intelligence. You tell it which relationships and meeting types matter most — investor calls, key customers, top candidates — and it books them into your prime hours automatically. Low-priority holds don't just get deprioritized. They get bumped, and the other party gets notified and rescheduled without you lifting a finger.

  • Set priority rules once — Arrangr applies them to every incoming request automatically
  • High-stakes meetings always get your sharpest hours — not whatever's left
  • Bumped meetings are auto-rescheduled with a notification — no awkward follow-up
  • Deep work blocks stay protected — internal syncs can't sneak in

Ari, Private AI

AI that schedules for you — without seeing your data.

Ari is Arrangr's built-in scheduling AI. It handles the coordination work — finding time, sending invites, predicting meeting priority based on your history — without routing your private calendar data through an external LLM. That means you get the speed of AI without the privacy trade-off every other tool forces you to make.

  • Predicts meeting importance based on who you've historically prioritized
  • Drafts and sends personalized 1:1 invites in seconds — not templates, actual context
  • Your calendar data never leaves Arrangr's infrastructure — Glass Box™ AI
  • Works silently in the background — no prompting, no babysitting required

I just got a warm intro to Maya Chen at Sequoia. Can you help me reach out?
On it. Based on your history, investor intros convert best when you reach out within 24 hours with a specific ask. I've drafted a personalized invite for Maya.
1:1 invite ready · "Maya, 20 min to explore fit?" · Send?
Yes — and protect my Tuesday morning for prep.
Invite sent. Tuesday 9–12am is blocked as deep work. If Maya books that window, I'll suggest Wednesday instead automatically.
Your calendar data stays inside Arrangr — never sent to an external AI model
