The corkage clause. The florist's VAT line. The cancellation window that closes Tuesday. All in one place, the way a planner who's done two hundred of these would lay it out.
She put three things on your calendar this morning. Two appointments and a reminder. Your phone will ping in the morning — you don't have to remember a thing.
She read the invoice while you were on the train. She filed it under flowers. She flagged the deposit. You opened the Workshop and it was done.
Forward her the florist's first reply. She files it on their card, pulls out the contact, the quote, the deposit. By the time you've made tea, the card is current.
The pot, the spend, the headroom. She tells you when photography's reached its ceiling and where the florals have room to give.
A hundred and thirty-eight names across fourteen tables. Two flagged conflicts she spotted before you did.
Your maid of honour holds the flowers. Your mother holds the timeline. Each gets their own dashboard, with just the parts they need.
About I Do
The biggest hurdle isn't the wedding day. It's the year before it.
Twelve months of admin, filing, chasing, watching the money. We looked at the apps trying to help and noticed they weren't really helping — so we built one that does.
The problem
Every other wedding app is paid for by someone else.
Some sell adverts. Venues, photographers, florists pay to sit at the top of your search. Others quietly harvest your data — your guest list, your date, your budget — and sell it on. Either way, the couple isn't the customer. The couple is the audience.
The answer
Build something that only works for the couple.
No adverts. No supplier kickbacks. No data sales. Your contracts, your guest list, your conversations with Iris — they live in your own Google Drive. We never hold them.
How it works
A senior planner, for the parts you'd rather not.
Iris is the assistant. The Workshop is the desk. You bring the wedding. She takes the year.
1
She meets you where you are.
Date set, venue booked, guest list half-written — wherever you are in the year, she picks it up. Tell her once. She remembers everything.
2
She reads what you forward her.
Send her the florist's invoice, the venue's contract. She reads it, files it, flags what needs your attention, drafts the reply if you want one.
3
She holds the year.
Calendar, budget, guest list, seating plan, dietaries, contracts, deadlines — all in one place, in your voice, in your hands.
4
She talks like a person.
Bring her the supplier who quoted twice, the seating argument. She's heard worse. She'll know what to do.
Journal
Coming soon.
Writing on the year before the wedding — what couples actually need, what the industry doesn't tell you, what Iris has learnt. Worth waiting for.
Privacy
Your data, kept where it belongs.
We hold as little of it as we can. What we do hold, we hold for you — never to sell, never to share with suppliers, never to feed back to advertisers.
What we hold
Your name and email, so we can recognise you and write to you about your invitation. The handful of identifiers that make the service work — your account ID, last sign-in.
What we don't hold
Your contracts, guest list, seating plan, budget figures, conversations with Iris — these live in your Google Drive. Your card details — Stripe handles those.
Who we share with
Google, Resend, Stripe, Anthropic. That's it. No suppliers. No advertisers. No brokers.
