Joy fixes a boiler and her customer taps to sign on her phone. A year later when the part fails, both of them can pull up the sealed job record without arguing about dates.

Why it is new

What exists today, and what this does differently

What is new

Blockchain-anchored job photos exist; a tradesperson repair warranty flow is less common.

Closest things out there

Kura and Record360 anchor inspection photos to blockchains, and WarrentChain stores warranties onchain, but none combine repair logs with customer signatures for tradespeople.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

Pro$9 a monthUnlimited sealed jobs, service reminders, Friday record, custom profile link
Crew$29 a monthEverything in Pro for up to 6 engineers, shared history, export for insurers

Prices are yours to set. Illustrative, not a promise of income.

BLUEPRINT

Why it matters and how it really works

The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.

The need

Small tradespeople lose time and money when customers dispute what was done and when. Paper job sheets get lost, and platform reviews belong to the platform, not the worker.

What exists and what is new

Close neighbours exist: Kura and Record360 anchor inspection photos to blockchains, and WarrentChain stores warranties onchain. What is less common is one simple flow built for a solo tradesperson: photos, a customer signature that works on any phone, warranty terms, and a public work history the worker owns. The pieces are not new, the combination for this user is.

The data it runs on

Unlocked when your app is paid in full

1.The mission

Every honest repair becomes a fact both people can check, and every tradesperson owns the proof of their craft.

2.Why people can't resist it

The argument that never happens When a part fails, both sides open the same sealed record. Dates and terms stop being a matter of memory.

A profile that is yours Hundreds of signed jobs form a work history no lead site can delist or charge to show.

Friday record A weekly summary of jobs sealed, a streak, and warranties ending soon, which doubles as a list of people to call for a service.

3.How it works for real

4.Pricing

Pro $9 a month

Crew $29 a month

5.Growth loop

Every sealed job sends the customer a copy with the worker's name and a link. Customers forward it to neighbours and family, profile links get shared in local groups, and service reminders bring the same customer back each year.

8.Where this is going

  1. Now
    Solo tradespeople seal jobs and settle warranty questions in minutes.
  2. Next
    Customers carry a home record: every repair on the boiler, wiring and roof, ready when they sell the house.
  3. Later
    Insurers and landlords accept sealed job records as evidence, saving inspections and paperwork.
  4. The world it builds
    Skilled workers everywhere own a verified history of their craft, which travels with them across cities, platforms and borders.

OWNER PLAYBOOK

Own it, then chart your voyage

NRevenueVentureBuilder statusHackathonsProductivityInspire othersPartnershipsPortfolioAgencyFIX PROOF

Nine routes from one vessel. Tap a port to open its chart.

Why own Fix Proof

Fix Proof lets a tradesperson seal each repair with photos and a customer signature, so a warranty claim a year later is a lookup, not an argument. Owning it means the trades firms that rely on it pay you, and every sealed job carries your brand into homes in your area. It is a quiet, trusted record nobody can edit, and you are the one who runs it.

What’s stopping you?

“I can't code.”

You don't need to. The app ships deployed to your wallet with a setup guide. Your work is standing next to one tradesperson for a morning and helping their first customers sign.

“Tradespeople hate new apps.”

Many do. Keep it to one tap after the job, and pitch it as fewer warranty arguments, not as crypto. Some will never switch, so start with the ones who already photograph their work.

“Is a sealed record a legal warranty?”

It is evidence of what was done and when, not a legal contract by itself. Firms should keep their normal written terms and use Fix Proof as the proof behind them.

“Is it really mine?”

Yes. The contracts deploy from your wallet, and the brand, domain and customer list are yours. DEPLOYR takes no cut of what you charge after purchase.

“What if it breaks?”

Records live onchain on contracts deployed from your wallet, so a page outage does not erase anything. Setup issues are covered by the get-it-shipped promise.

The million-dollar ladder

Trades firms pay a monthly plan per van or technician, and trade associations pay for a branded version for members. Reaching $1M a year is a target to plan toward, not a promise. Most growth comes from associations and suppliers, not single traders.
