Three clients need your attention. Crucible already started.

The real problem

Your coaching platform is a
filing cabinet.

You store programs in one app. Meal plans in a spreadsheet. Content in Canva. Captions in ChatGPT. Four tools that don't share a single data point between them.

A client's weight stalls for a month and you don't notice until the next check-in. Someone skips three sessions in a week and there's no flag, no alert, nothing. You catch it late, scramble to re-engage, and wonder how you missed it.

× One app for programming
× Spreadsheets for nutrition
× Canva for content
× ChatGPT for captions

That's 10-15 hours a week on admin. A quarter of your working week, gone. And you're still reactive.

Crucible connects all of it. And watches what you'd miss.

Your second pair of eyes

Crucible catches what
you'd miss.

Every weigh-in, every logged workout, every skipped session feeds Crucible. When a pattern needs your attention, it surfaces on your dashboard with a recommended next step already drafted.

Weight trend flat 4 weeks → Nutrition plan drafted
Draft: Nutrition Adjustment — Sarah M. Ready

Weight held at 68.2kg for 28 days on 1,850 kcal. Likely adapted. Suggested: drop to 1,650 kcal for 2 weeks, add a 10-min walk on rest days, reassess at next weigh-in. Protein stays at 140g.

Review & Send
3 missed sessions in 7 days → Engagement alert
Draft: Check-in Message — Jake R. Pending

Edit Message
Program ends in 7 days → Next phase ready
Draft: Phase 3 Program — Megan K. Ready

Review Program
Target weight reached → Message drafted
Draft: Milestone Message — Emma L. Ready

“You did it — 63.0kg this morning. Twelve weeks of work, right there on the scale. Let me know when you want to chat about what’s next.” Maintenance plan templated.

Send Message
Check-in 2 days overdue → Reminder queued
Auto: Gentle Reminder — Tom S. Queued

Sunday check-in not received. Tom’s been consistent for 9 weeks — probably just forgot. Gentle nudge queued for tomorrow 9am. Auto-cancels if he checks in before then.

What's inside

Everything your coaching business runs on.
One login.

AI Programs

Describe what you need. Get a periodised program built from your client's history, goals, and limitations. Every edit teaches the system your coaching style.

AI Nutrition

Meal plans from real calorie and macro targets. When a client's weight trend shifts, Crucible recommends an adjusted plan. You review and send.

AI Memory

Every edit trains it. Remove barbell rows three times, it stops suggesting them. Rewrite a check-in message, it learns your tone. After a month, first drafts feel like yours.

Content Engine

Carousels, posts, and stories from a single prompt. Your photos, your voice, export-ready. Sunday Canva sessions are over.

Client App

Clients log workouts, track food, and complete check-ins from their phone. You see everything without chasing a single message. iOS and Android.

Payments

Sign up a client during the call. Card clears before you hang up. Billing, invoices, pauses, cancellations. You never chase a payment again.

Common questions

When does Crucible launch?
We're building now and letting founders in as we go. Claim your spot and you'll hear from us directly when it's your turn.
What will it cost?
Founding coaches lock in the lowest monthly rate when pricing goes live. Once it's yours, it's yours — no price hikes, ever.
Can I bring my existing clients over?
Yes. Add clients manually at launch, with bulk import tools following shortly after.
Is the client app real?
Native iOS and Android. Your clients download it, log in, and train from an app branded to your coaching business.
I'm already using Trainerize / TrueCoach / Everfit. Can I switch?
Yes. Crucible is built to replace your entire stack, not sit alongside it. We'll help you migrate clients over when you're ready — no awkward transition period.
