Tangerine Design Platform
The workspace where factories and their customers design, quote, and ship custom products together.
Brands bring an idea. The factory's real cost model turns it into a priced, dated quote. Everyone watches the same order through sampling, production, and reorder.
Auto-quote from your real cost model
Your tooling, material, finish, and MOQ rules become instant quotes. No spreadsheet round-trips.
Free customer acquisition
Buyers arrive with a finished spec, not a 'just looking' email. You pay nothing until an order closes.
AI design that cuts labor
Concepts and DFM checks come back drafted. Your designers refine instead of starting from zero.
Free AI hardware design
Describe the part. Get concept directions back in a day — no design firm, no retainer.
Real factory-grounded quotes & lead times
Pricing computed from the factory's actual costs, not a guess. Dates you can plan a launch around.
Live order + yield tracking
Watch every batch move through the floor. First-pass yield, defect notes, QC photos — nothing hidden.
How it works
Five steps from idea to repeat order.
Design
Configure the part or describe it. AI returns concept directions in the factory's house style.
Quote
The factory's cost model prices it instantly — unit cost, MOQ, lead time, payment terms.
Sample
Approve a direction, get a physical sample. Sign off before any tooling is cut.
Produce
Track the run live — stage by stage, batch by batch, with first-pass yield in view.
Reorder
Ship it, then reorder the exact spec in one tap. The factory keeps the relationship.
