residualGet paid for the parts you've already made.
AI companies are paying manufacturers for years of engineering changes, quality reports, RFQs and supplier email. We check if yours qualify, introduce you to the right buyer and stay with you until you're paid.
Two minutes. No access to your systems. Nothing upfront.
What manufacturing companies like yours can earn.
It depends mostly on how many office, engineering and planning staff you have, and how many years of records you keep.
Our market estimate for a US company with 8–12 years on its tools, built from three buyers' published pricing. Staff means office, engineering and planning staff. Not an offer: the buyer sets the price after review.

Engineering changes and drawings
How a design change moves from request to production without breaking anything downstream.

Quality reports: NCRs and CAPAs

Your clients and team are never named.
Before anything is delivered, an independent firm swaps every name, contact detail, address and reference number for a consistent placeholder. The work stays readable. The people in it don't.

Illustrations; all names are made up. Before you sign anything, you see the method and a de-identified sample of your own records.
Nothing upfront. You only pay if a deal completes.
Our success fee is agreed privately, in writing and under a mutual NDA, before we introduce you to anyone. No deal, no fee.

8–16 weeksManufacturing companies with years of decisions in writing.
- 30+ office, engineering and planning staff, now or at your peak
- 3+ years on the same email and ERP
- Changes and problems handled in writing: email, ECOs, NCRs, tickets
- Customer drawings under NDA and export-controlled data can be left out
- US or UK, mostly in English
Line and warehouse workers don't count toward size, and don't need to. Operating, winding down or closed: all can qualify.
Questions owners ask us
What about customer drawings under NDA?
Left out by default. Only records your company owns and is free to license are included, and you approve the scope in writing.
We handle ITAR or export-controlled work. Can we still qualify?
Often, yes. Export-controlled data is excluded entirely, and the rest of your operational record can still qualify. We check this on the first call.
Do line workers count toward the 30 staff?
No. Buyers count office, engineering, quality, planning and admin staff.
What does it cost?
Nothing upfront. If a deal completes, you pay our success fee, agreed in writing under a mutual NDA before any introduction. No deal, no fee.
