How the Weekly Pot Works

2026-07-14 · Raiden Team

Every dollar that moves through Raiden takes the same trip: an advertiser pays for impressions, the charity portion of that revenue lands in a shared weekly pot, and at the end of the week the pot is divided up and pointed at real charities. There's no mystery step, no black box in the middle. This post walks the whole path, because we think you should be able to follow a dollar from one end to the other.

Where the money comes from

Ads appear in feeds on Raiden, and advertisers pay for the impressions those ads get — the same arrangement that funds most of the internet. The difference is what happens next. After Raiden's operating costs, the charity portion of that revenue goes into one transparent pot for the week. Not a pot per person. One pot, for everyone, refilled continuously as ads are shown.

The week is the unit

Raiden runs on ISO weeks: Monday through Sunday. All the ad impressions tracked during that window, and all the charity revenue they generated, belong to that week. When the week closes, a distribution runs, and it runs exactly once — each week's run is recorded so it can't accidentally happen twice or get quietly re-done with different numbers.

How the pot gets divided

The distribution answers one question: whose attention generated this week's pot? Each profile's slice is proportional to its share of that week's tracked impressions. If the ads shown alongside your activity accounted for 2% of the week's impressions, then 2% of the pot is directed according to your choices.

Two conditions apply, and they exist for the same reason: money is never left undirected. A profile participates in a week's distribution only if it had impressions that week and has a giving allocation set. No impressions means no share to direct; no allocation means no instructions for where a share should go. Money without a destination doesn't sit in limbo — the pot divides among the profiles that can actually direct it.

Your split does the pointing

Every member sets a giving split: percentage allocations across up to five charities, summing to 100%, editable anytime. When the distribution runs, your slice of the pot is divided by those percentages. Then everything is aggregated per charity — your 40% to a food bank joins everyone else's allocations to that same food bank, and the week produces one total per organization.

The arithmetic is exact, and that's on purpose

Dividing a pot by impression shares and then by percentages produces fractions that don't fall neatly on cent boundaries. Most systems handle this by rounding and shrugging at the leftover. We don't. Raiden does the math in micro-precision integers and uses largest-remainder rounding — an old, boring, well-understood method — at every split. The result: the per-charity amounts always sum back to the pot exactly. No dust dropped, no dust invented, conserved to the micro.

Underneath all of it sits a double-entry ledger. Advertiser money in, charity money out, every entry matched against another. The totals you see are computed from those entries, not read from a stored number someone could edit. We've written about that structure before; the short version is that all the entries have to sum to zero, and the math itself catches anything that doesn't.

The last step: Every.org and the EIN

Per-charity totals route to their organizations through Every.org, which supports more than a million U.S. 501(c)(3) organizations, each identified by its IRS-issued EIN. That's why your split can point at a tiny local nonprofit as confidently as a household name — the EIN, not the name, is what gets matched.

Where we are right now

Raiden is in founding preview. The weekly runs happen exactly as described — impressions tracked, pot computed, splits applied, per-charity totals produced and recorded — but they're projections: they show precisely what the model would direct, and no real money has moved yet. When giving goes live, nothing about the mechanics changes. The pipeline you can watch today is the pipeline that will carry real dollars, which is exactly why we built it in the open first.

That's the whole trip. Advertiser to pot, pot to shares, shares to splits, splits to charities, charities by EIN. Every step is arithmetic you could check yourself, and that's the point.
