The Design Philosophy of DIY Partners

—— The one who does the work takes 90%. This principle dissolves the scalability wall.

1. The Scalability Wall

Sato plus one production collaborator. The number of venues we could reach equaled the number of weekend trips we could make. The collaborator had a full-time job elsewhere; Sato was running all of TokiStorage solo. At this pace, a handful of weddings per month was the ceiling. What we needed was a system that could run without us being physically present at every venue.

The root of the problem was dependence on human travel. No matter how good the product, as long as manufacturing and delivery required someone on-site, revenue was capped by available person-days. The bottleneck was not technological. It was physical.

2. Not a Dealer. The Venue Becomes the Manufacturer.

The dealer model is "buy and resell." The venue assumes inventory risk and layers on margin. The difference between wholesale and retail is the profit. Simple enough, but the venue is left feeling like a sales window for someone else's product — not offering its own service.

The DIY Partner model is different. The venue manufactures the keepsakes itself and offers them as its own service. With a UV laminator and standard A4 paper, a finished voice QR keepsake takes about five minutes to produce. For the venue, this is not outsourcing. It is an in-house menu item. A wedding planner can propose it naturally as part of the ceremony program.

This distinction matters. A dealer needs external motivation to sell. A DIY Partner's motivation to create comes from within. When you make something yourself, you recommend it with confidence.

3. The 90/10 Principle

No licensing fees. No monthly subscriptions. There is only one rule: the one who does the work takes 90%.

When a venue manufactures and delivers the keepsake through DIY, 90% of the revenue stays with the venue. Headquarters receives 10% as a technology and platform fee. Conversely, when headquarters handles manufacturing and shipping for a standard order, headquarters takes 90%. Nobody loses. Incentives align directly with action.

This principle eliminates the need for franchise contracts. No royalty negotiations, no minimum order volumes, no thick binders of contractual terms. You keep what you earn. If you do nothing, you owe nothing. Because the rule is simple, explaining it takes almost no time at all.

4. The Technical Beauty of a Single Checkbox

Implementing this entire system required one checkbox on the order form and a single if-statement in Google Apps Script.

The existing Wise payment flow, partner tags, and monthly reporting all continued to work without modification. No new API. No new database. No new admin panel. A venue creates a Wise account, enters its username on the setup screen, and the existing pipeline handles the rest.

A technically beautiful solution is not one that requires writing a mountain of code. It is one that introduces the smallest possible change to existing infrastructure and produces entirely new behavior. One checkbox changes the business model. That is the power of design.

5. What Each Side Brings

Printing QR codes and applying UV laminate requires no specialized skill. Anyone with a printer and a laminator can do it. That is precisely why it can be entrusted to the venue.

Meanwhile, the permanent storage pipeline on GitHub and the deposit at the National Diet Library of Japan are infrastructure that headquarters has built over a long period of time. Behind the promise of "preserved for 1,000 years" is the ongoing maintenance and operation of this preservation foundation.

The venue delivers the best possible experience to the couple standing before them. Headquarters safeguards the infrastructure that carries those voices a thousand years into the future. Each side contributes what it does best. This complementary relationship forms the foundation of the DIY Partner model.

6. Conclusion: Democratizing Wedding Keepsakes

Without specialized skills and without expensive equipment, a wedding venue can now create keepsakes that preserve voices for 1,000 years. Using an A4 printer and a laminator that costs less than 10,000 yen.

Everything needed was already there. All we had to do was unlock it.

The one who does the work takes 90%.
This principle dissolves the scalability wall, eliminates the need for franchise agreements, and transforms venues from outsourcers into manufacturers.
Defended by technology, driven by principle. That is the design of the DIY Partner.
