A funding instrument that resolves

Simple Agreement for Future Redemption

A SAFR™ is a claim that grows on a published schedule, elected once at issuance, and settles in cash each quarter, or converts to equity, with verified numbers published on the same calendar every year. No maturity date to default against. No valuation to argue over. A cap, so it cannot run away from you.

If you are a founder

It is a mortgage you can pay off, not a claim that lingers on your cap table with no way to clear it.

If you are an investor

It is an early-stage claim with a believable path to getting paid back, and a quarterly look at how the company is doing.

01

What a SAFR is

You invest. In return you hold a claim on the company worth your money times a Multiple that rises on a published schedule elected at issuance. For a typical startup that is the Fixed Pool schedule: 1.50 from the day you invest, with a hard cap of 2.50. The company settles that claim in cash at quarterly windows, as much as it declares it can afford, or you can convert into stock. That is the core of it.

The convertible note

Comes due on a date. If the company cannot pay or raise by then, everyone is in a default fight nobody wins.

Fails on time

The SAFE

Solved that by deleting the date. But if the company never prices a round, the SAFE never converts and never resolves. It just sits there.

Never resolves

The SAFR

Keeps the schedule but ties payment to what the company can verifiably afford each quarter. The claim is capped, and it always resolves.

Resolves on capacity

It replaces a deadline that can be missed with a budget set to what the company can afford, on a calendar everyone shares.

02

Why it exists

The SAFE was built for one world: high-velocity companies where a priced round was nearly certain and speed was the only constraint. Exported to everyone else, it became a trap.

Most companies that raise on a SAFE never reach a priced round or an exit, which are the only two events that make a SAFE convert. So most SAFEs become what the research calls zombie paper: held by people who will never get equity and can never get paid, with no maturity to force the question and no information rights to even see what happened. The instrument’s defining feature, that it never comes due, is exactly what strands the ordinary angel.

SAFR is for that large unpriced middle: companies that may never raise a Series A but can generate cash. Instead of a claim resolved by an event that may never come, it is resolved by the company’s own capacity, measured and published every quarter.

03

How the Multiple works

Your claim is your unreturned investment times the Multiple. The Multiple follows one of two published schedules, elected once on the first page of the agreement, for the life of the position. For a typical startup that is the Fixed Pool schedule: the Multiple is 1.50 from the day you invest and never below it, holds at 1.50 through month 36, rises to 2.00 at month 60, and is capped at 2.50 from month 90 on. Between the anchors it moves in a straight line, and it never decreases.

The other schedule: Direct Ledger

The second schedule, Direct Ledger, is calibrated for an issuer whose conversions mint ledger-backed units rather than issuing shares from a fixed pool. It opens at 1.00, holds there through month 12, and is capped at 1.60 from month 90. A venture carries one elected schedule across all of its positions, and every Quarterly Update states which one. When and why a company elects it is covered in section 08 below, on companies that are not corporations.

The ways it can resolve

You can join the redemption queue and be paid in cash from the company’s declared budget, pro rata with other holders; the queue opens at month 60, or as early as month 36 if the company opens it. From month 36 the company can also buy you out at the schedule price, and if it does, you may choose to convert the noticed amount instead rather than take the cash. From month 36 you can convert a slice each quarter into common stock at the published Ledger Base price, the path for when you reach the cap and would rather own equity than keep waiting. The company can also extend you a Conversion Offer: an invitation to convert at the Ledger Base price that must state what the converting capital is for, and that you can simply decline; ignoring it declines it, your position is unaffected, and silence never accepts equity. A priced round is different, and better: you can convert the entire position at the round’s own price, less a 20% discount, in a single move rather than the quarterly slice.

Zero is never default. If the company declares a budget of zero in a slow quarter, nothing breaks, nothing accelerates, no one is in breach. It owes a one-line written explanation, and the meter keeps running on the schedule. That is the difference between a budget and a deadline.
04

What it costs the company to wait

On the Fixed Pool schedule the claim stands at 1.5× from day one and holds there through month 36, so early on, waiting adds nothing: the floor was priced in at issuance. From month 36 the claim climbs toward the 2.5× cap, and that is what the figure below shows: the cost added each quarter, as an annual rate, for a position that stays outstanding. The climb is steepest just after month 36, eases at month 60, and falls to zero once the Multiple is capped, at which point the company owes the full amount and it simply stops growing. The company decides quarter by quarter, so the cost is drawn as steps.

Months since the investment, along the bottom, on the Fixed Pool schedule. This is the cost added each quarter for a position the holder neither redeems nor converts; the amount owed itself stands at 1.5× from day one, then rises to the cap and never shrinks. While the floor holds, through month 36, nothing further is added. The climb begins after month 36, at roughly 17% a year, and steps down. The clear drop at month 60 is the schedule easing from a 0.0625 to a 0.05 quarterly climb, the moment pressure rotates off the company. After the cap at month 90 nothing more is added, so a struggling company is never crushed by a compounding penalty, while a company with cash is rewarded for resolving early. Throughout, the holder’s alternative to waiting is conversion: trading the cash claim for equity rather than staying in the queue.

Months 36–60

The climb begins, and favors resolving

  • Reporting begins, the company can buy out positions, and the holder can begin converting; the climb is steepest here.
  • The holder earns a steady return for the wait.
  • Resolving early is genuinely cheaper than almost any other startup capital.

Months 60–90

In the middle, both sides have room

  • The queue is open and the climb eases, so the company can defer when cash has better uses.
  • The holder can redeem, keep converting, or keep waiting.
  • Neither is forced; the schedule steps back and lets capacity and preference decide.

At the cap (month 90+)

At the cap, the holder chooses

  • The Multiple stops growing, so waiting adds nothing further.
  • The amount owed stands at the cap; it neither grows nor shrinks.
  • A quiet nudge to pick a path: redeem through the queue, or convert to equity.
05

The life of a quarter

Every SAFR company runs on the same four fiscal quarter-ends, which turns reporting into a shared rhythm: the whole network publishes in the same weeks, like an earnings season for companies that never had one.

You elect

Holders lock in their moves for the quarter: redemption requests, conversion elections, and responses to any buyout notice or conversion offer.

The company updates

The Quarterly Update publishes: standardized net worth, expected capacity, the declared budget, and a single owners-and-leaders pay total. Computed from the data feed, not asserted.

within 10 business days of the update

It settles

Cash redemptions and buyouts pay, conversion shares issue. The update already fixed the budget and each holder’s share, so settlement just pays it out. Then the cycle begins again next quarter.

The numbers in the update are produced by one fixed formula applied to every company, so the market forms an expectation before the company says a word, and the company then meets it, misses it, or beats it. Over time that sequence becomes a quarter-by-quarter capacity history, the kind a SAFE never produces.

06

The two numbers that matter

The formulas behind a Quarterly Update live in the open Standard. To read one, you mainly need to know what two figures mean.

Ledger Base: the company’s standardized net worth

One fixed formula values what the company owns, the product development it has funded, and its revenue weighted by quality. It is never a negotiated valuation and never uses comparables, so it means the same thing across every company. Every dollar of economic value enters through exactly one category: revenue a company’s own leased-out asset produces, for example, is never counted on top of the asset itself. It sets the conversion price and feeds the capacity figure.

Expected Capacity: what it could prudently pay this quarter

A quarter of free cash flow, after keeping a working-capital reserve. The company’s own declared budget can be more, less, or zero, but when it is less, it must say why. The figure below is the real worked example from the sample Quarterly Update.

Ledger Base composition and Expected Capacity (worked example)

Tangible net assets
$620,000
Development asset
$111,000
Revenue value
$470,000
Ledger Base
$1,201,000
Expected capacity
$37,000
Declared budget
$25,000
Tinwheel Systems (a worked example), quarter ending March 31, 2026. Ledger Base of $1,201,000 is the sum of tangible net assets, the amortizing development asset, and revenue value. Expected Capacity of $37,000 is bounded by a quarter of free cash flow; the company declared $25,000 and explained the gap.
07

Reading it from your seat

If you are a founder

A forcing function you can live with

  • The data feed runs from closing, with free tools to set it up; Quarterly Updates only begin after month 36.
  • You control the levers: the declared budget each quarter, whether to buy out positions or offer a conversion, whether to open the queue early.
  • The data you share is aggregate. No individual pay, no customer names, no pipeline.
  • Conversion lands in common, never preferred, so it never complicates your next round.
  • The Form D is generated at closing, so the round is filed rather than left undone.

If you are an investor

A claim that resolves, and that you can watch

  • Three real paths to resolution, not one event that may never happen.
  • A quarterly, verified look at the company’s net worth and capacity.
  • Conversion is your option for the upside cases; you are never forced into it.
  • The downside is real: the claim is tied to net worth and, in failure, drops to your unreturned capital. This is risk capital.

If you hold a SAFE, note, or CISA

You can graduate onto these rails

  • Your existing claim crosses into a SAFR at par, once the company has four clean quarters of capacity.
  • A note or income share keeps its age on the schedule; a SAFE, which never priced time, starts fresh.
  • Side letters fall away; everyone gets the same reporting. Any equity you held stays yours, untouched.
  • The offer is made to every holder of your instrument on the same terms.
08

When the company is not a corporation

A SAFR works for any company, corporation or not. If the company is not a stock corporation, conversion delivers that entity’s version of common: ownership units carrying the same economic rights, with governance set by the entity’s organizing documents. Conversion never produces anything senior: no preferred, no liquidation preference, no special voting or blocking rights.

Some of these entities keep their books in one unit of account. The ledger is stated in it and ownership is denominated in it, so a unit is a direct claim on what the ledger holds. The instrument prints a schedule calibrated for that bookkeeping, named Direct Ledger, elected by checkbox on the first page alongside Fixed Pool. The two names describe two mechanics.

Fixed Pool

Shares served from a pie

Fits a company whose conversions issue shares from a fixed equity pool: the company is a pie, cut into shares, and every conversion serves slices from that same pie. Because the pie is fixed, the dilution cap protects it: no single position converts past 25% of the company, enforced as a price floor.

Direct Ledger

Units minted against the ledger

Fits an issuer whose conversions mint new units against assets already on the books. Conversion is priced straight off the ledger, Ledger Base per fully diluted unit, with no floor, because there is no fixed pool for a cap to protect. Units issue at the ledger’s own measure, so total claims stay matched to the base behind them. The schedule opens at 1.00 and holds for twelve months; in that window the claim is the money in.

1.00× for the first 12 months · capped 1.60× at 90

The election is made once at issuance and is independent of the company’s form and tax status. Direct Ledger is simply the calibration built for ledger-denominated structures, which is why you will usually meet it there.

In some of these structures, economics and governance can be held separately. Operators hold both; passive holders hold the economics, and the entity’s documents set how governance is delegated. If you convert into such a structure, your economic claim is the same as common, and your conversion materials state plainly how governance works there. The instrument stays the same for everyone; the structure you convert into is disclosed up front.

One more record sits on the first page, whatever the entity’s form: how the company is taxed. It earns its own section, because taxes are where the SAFE and the SAFR part ways.

09

How taxes are handled

The SAFE assumes one kind of company, a Delaware corporation, and says nothing about tax. A SAFR can be issued by any entity, so it writes the tax facts down and keeps the paperwork matched to them. The first page records whether the company is taxed as a corporation or as a partnership, whatever its legal form, including a trust or series taxed that way. It is a record, not a choice, and it is carried in every Quarterly Update, so a change is visible to every holder in the quarter it happens. A change of tax classification alone triggers nothing.

Where the record earns its keep is conversion. When you accept a Conversion Offer, the exchange is executed through a short Conversion Declaration matched to the company’s tax classification, so the paperwork is right for the entity you are converting into, on the day you convert.

First-page record · how the company is taxedrecorded, not elected

Taxed as a corporation · Exhibit 1-A

Your conversion papers as an exchange with the company itself: the claim is surrendered for common stock, intended as a contribution to the company or a recapitalization of its existing obligation, not as a sale of your position.

IRC §351 / §368(a)(1)(E)

Taxed as a partnership · Exhibit 1-B

Your conversion papers as a contribution to the company in exchange for ownership units, not as a sale, and you are admitted as a member or partner from the day the conversion takes effect.

IRC §721(a)

Whichever column applies

  • The date is fixed in writing. The Conversion Declaration sets the effective date, and you own the units, with the benefits and burdens of ownership, from that date. Where an offer is made to align your equity with a specific asset purchase, that date comes before the asset is acquired and placed in service, so the order is never in doubt.
  • Both sides file consistently. The parties agree in the Declaration to file their returns on the intended treatment and to take no position against it.
  • The instrument gives no tax advice. It states the intended characterization and stops there. The treatment itself lives in the offering’s separate tax materials, which are what you review with your own advisor.

The point is not a tax opinion. It is that the tax facts are written down, the paperwork matches them, and nothing about your position turns on a fact you cannot see.
