$0 → $1M+

Direct-to-consumer orders for independent jewelers.

Ad Research

50,000+

Jewelry and watch ads analyzed.

Ad Spend

$20M+

Managed, with $200M+ in spend audited.

How We Work

Full-service, and we prove every dollar of it.

The Operation

Full-Service. Full Proof.

Strategy, paid media, creative, SEO, web development. We run it all for luxury retailers and track every dollar to a real outcome — online checkout, phone call, or showroom visit. No piecemeal vendors. No guessing what worked.

The Proof

Then We Show You What It Did

CRM integration, appointment tracking, e-commerce attribution, geo-fencing. Every campaign tied to actual sales. You check it against your own records.

Access

You Talk to Us

Senior strategists run your account. The person who builds the plan is the person you call on Tuesday.

Patience

Built for the Considered Purchase

High-ticket buyers research for weeks, compare, come back. We stay in front of them until they're ready.

The Attribution Moat

We connect your ad spend to your register.

The hard part in jewelry isn't running ads. It's knowing which one brought someone into the showroom three weeks later, then closed over a glass of scotch. Our attribution platform ties an Instagram tap or a Google click to the actual sale, online or in person. It pushes past Safari's cookie limits, matches in-store email captures back to the original click, and dedupes revenue across Google and Meta, so the ROAS you see is the ROAS you got.

The Gray-Market Problem

Your Buyer Is Price-Checking You on Their Phone, In Your Store

Every serious buyer walks in with a tab already open to a gray-market dealer. The fight is not price, it is trust, warranty, and the experience of buying from an authorized dealer. We build campaigns that sell all three, so you never have to discount to win.

The Long Research Arc

An Engagement Ring Buyer Shops for Three Months. A Watch Collector for Six.

Nobody buys a $12,000 watch on impulse. We build retargeting, email nurture, and review programs that keep your store in front of buyers across the entire research window, then turn every closed sale into the relationship that brings them back.

Why H&CO

What Makes This Agency Different

6+ Year Average Client Retention

Our average client has been with us for over six years. We keep clients because we produce results they can verify against their own books, not because of long contracts.

100% USA-Based Team

No outsourcing. No offshore teams. Every strategist, designer, and developer working on your account is in the United States. You talk to the people doing the work.

AI-Native Agency

We use AI across every discipline to deliver more output with less overhead and build personalized campaigns that were not feasible three years ago. The savings go into your results, not our margins.

Most agencies show you a dashboard. We show you which campaigns put people in your store, which ads drove online sales, and which dollars were wasted.

If you can't tie it to the register, it didn't work.
