We operate like the in-house CMO and marketing team you have always wanted to hire.

Trade areas served

NYC and tri-state at the bench. Anywhere remote.

The studio is in New York City. The work runs from here for jewelers in the city, the surrounding trade areas, and brands across the United States. Single jeweler per trade area, defined by the founder before any engagement starts.

// 01
Diamond District & Midtown
The Forty-Seventh Street corridor and the surrounding Manhattan jewelry trade.
// 02
Manhattan & Brooklyn
Independent fine jewelers across the boroughs, including the Williamsburg and DUMBO showroom scene.
// 03
Long Island & Westchester
Brick-and-mortar fine jewelers north of the city and out to the East End.
// 04
Connecticut & New Jersey
Tri-state jewelers within trade reach of the NYC market, including Greenwich, Stamford, and the Jersey shoreline.
// 05
National & remote
Fine jewelers anywhere in the United States outside a competing trade area. Operated remotely from NYC with monthly working sessions.
// 06
One per trade area
We will not work with two jewelers in the same trade area at the same time. Onboarding is selective by design.
Why NYC, and what that means for your account

The studio is in NYC. The discipline is in every account.

Being based in New York City is not a marketing line. It is how the studio operates. The founder lives within walking distance of half the trade. The pace of the city, the standard of the jewelers here, and the directness of the work get applied to every engagement, in NYC or out.

No junior account managers. No binding contracts. You own everything when an engagement ends.

What we operate, end to end

Two ways in

Apply, or audit first.

If your trade area is open, apply for a partnership and the founder reads it within one business day. If you want a written look at your visibility before any conversation, request the AEO and SEO audit. No binding contracts on either path. You own everything.
