A guarantee is only as good as its ruler. Here's ours.
Most guarantees hide their measurement method. We publish ours, because the whole point is that you can check us.
What we measure
Yield is finished flower divided by total dried weight, where total dried weight is finished flower plus trim. Two numbers your compliance records already contain. Trim means plant material removed in processing that is sold or processed as trim; unusable waste (stems, contaminated material) is excluded from both sides of the equation, and we agree on that classification with you in writing before anything is measured.
The moisture rule
Flower weighed wet reads heavier than flower weighed dry, so two honest measurements can disagree by points if they happen at different dryness. Every weight in the baseline and every weight after install is taken at 0.60 water activity or below, matched within 0.02 between baseline and result, verified by meter on both sides. Without this rule a yield guarantee is an argument waiting to happen. With it, the number is the number.
Your baseline is your own data
The yield guarantee is set from five harvests of your records, pulled from your books, computed with the formula above. We don't measure your baseline; you already did. If your five harvests swing wildly, we work with you to understand why before any number is guaranteed, because a guarantee against a noisy baseline protects nobody.
Where the guarantee is payback rather than points, the same principle holds harder. Before install, our solutions engineering team freezes the savings model in writing: your flower reference price, your loaded labor rate from payroll, your grade price deltas from your own price sheet. After install, quantities get measured and plugged in; the model never moves. Payback is assessed at month three: your actual monthly run rate against the frozen model, extrapolated to six - documented savings against everything you've paid to date (implementation and fees; the deposit doesn't count, it's yours). A miss triggers then, not after six months of fees. No post-hoc modeling, no negotiated spreadsheets.
The Performance Guarantee, in full
| The yield guarantee | A recovery of 5 to 10 points, with your exact number set from five harvests of your own records. Eligibility: operations currently below 70% yield. |
|---|---|
| The payback guarantee | Marvel pays for itself within six months, measured against a savings model frozen in writing before install - your flower reference price, your loaded labor rate, your price sheet. The value counts wherever it lands: yield, labor, or grade. |
| The accuracy floor | At least 80% grading and sorting accuracy, specified for your operation by applications engineering and written into the guarantee. |
| How the numbers are set | We guarantee 80% of what our model expects to deliver - the expected number and the guaranteed number appear on the same page you sign. If the model can't clear the bar with room to spare, we don't take the deal. The highest guarantees attach to the lowest starting yields - below the range where our documented evaluations ran, which is why the guarantee band tops the documented one. |
| How it's measured | By the published method on this page: yield as finished ÷ (finished + trim), weights at matched moisture, meter-verified, classification agreed in writing before anything is measured. |
| The clocks | Operating claims run 90 days from install. The payback guarantee is assessed at month three - your actual run rate against the frozen model, extrapolated to six - so a miss triggers early, not after six months of fees. |
| If we miss | Your deposit comes back and your monthly fees stop. The implementation fee is retained - it paid for real work. |
| Where it applies | The managed model. Outright purchases don't carry the guarantees - which is most of why the managed model exists. |
How the demo is scored
Before any demo, the Keirton Blueprint runs: data collection, value stream mapping, and a tailored ROI case - the same model the payback guarantee freezes in writing. The demo itself is run by our team, because the improvement comes from changing how the line runs, not from bolting a machine onto the old process. Every weight is recorded jointly and you verify each one live, on your scale. Nothing goes in the books that you didn't watch land on the scale.
What happens if we miss
Simple, and in the contract in the same words: if Marvel doesn't perform as guaranteed, your deposit comes back and your fees stop. Operating claims run 90 days from install; the payback guarantee is assessed at month three, your actual run rate extrapolated to six - you know early, not after six months of fees. Both measured by the method on this page, on your records. We're not the scorekeeper. You are.

Seriously. Ask us to walk through every line of it against your operation. A vendor who flinches at their own measurement protocol is telling you something.
