Product Development

One partner for the whole product development process.

From the first mood board to the first sample on the table, product development moves through a lot of hands. I do the work I do best in-house, coordinate the rest through partners I trust, and stay in the room for all of it. One point of contact. One process. Built to ship.

Step 1: Mood Boards & Concepts

Before we draw anything, we lock the look and feel. Visual references, color direction, fabric character, and competitive context, so the product has a point of view, not just a silhouette.

Step 2: Fashion Flats

Clean 2D sketches with colored flat renderings that show your product from every angle. Front, back, side, construction details. The first version of your product anyone outside your head can actually see.

Step 3: Tech Packs

The technical design and blueprint of your product. Measurements at base size, points of measure, materials and trims, construction notes, grading rules. Everything a factory needs to make your sample right the first time.

Step 4: Pattern Making

The translation from flat sketch to a pattern your product can actually be cut from. Handled through pattern makers I've vetted and worked with directly, coordinated to fit your tech pack.

Step 5: Fabric & Factory Sourcing

Matching your product to fabrics that exist and factories that can build it. Vetted on capacity, matched on category, chosen for long-term fit, not the cheapest yes.

Step 6: Sample Making

Coordinating the first physical version of your product with sample makers I trust. I translate between you and them so nothing gets lost on the way from spec sheet to garment.

Step 7: First Sample Review

Reading the sample against the tech pack: fit, construction, fabric behavior, and what to revise before round two. The job is to read the data, not panic at it.

Step 8: Fit Revisions & Sample Rounds

The work between first sample and approved sample. Most founders don't realize this is its own phase. Reviewing fit, sending comment sheets, coordinating round two and round three samples until the product is right.

Step 9: Pre-Production Approval

The final sign-off before bulk production. Confirming the PP sample matches spec, locking the final tech pack, confirming materials and trims are ordered, and giving the factory the green light. The handoff from development into production.

The timeline

From mood board to production-ready.

How the work gets done

Whatever you need, it gets done right.

From mood board to sample approval, you get one team and one process. My team and I handle every step — design, technical, sourcing, sampling, review — so you're not chasing five different people across five different conversations. One point of contact. One standard of work.

The principle

Why I run product development this way.

The first product I ever developed taught me where the breakage points really are: not in any single step, but in the spaces between them. A clean tech pack handed to the wrong sample maker. A great pattern paired with the wrong fabric. The right factory chosen at the wrong moment. So I built a process that owns the whole arc — the work I do, the work I coordinate, and the translation between every link in the chain. That way the next founder doesn't have to learn it the same way I did.
