THE HOUSE NEW YORK CITY EST. MMXXV

One operator. Every account. On purpose.

Endico Data Strategic is a New York City marketing studio built around a single conviction: the person who wins your business should be the person who does your work.

THE OPERATOR · I

One name on every account.

No partners · No juniors

Most agency relationships are sold by a partner and delivered by a rotating bench of juniors, then measured in impressions and reach because those numbers are easy to make look good. William Endico built this studio to remove that gap: one operator, four channels, and a scoreboard that only counts revenue.

That is not a slogan. We care about your growth as much as our own. The person who took your call is the person running your account next month and next year, and you can check the work yourself: find the founder in public on LinkedIn.

I absolutely love working with Will and Endico Data Strategic, and I am so happy he found us! Over the years I have worked with a variety of digital marketing and ads teams. They have done a fine job, but used vanity metrics without any explanation to keep us on to maintain their retainers. They never deep dived into our business our customers to figure how to strategically make our ads and money work for us. When Will found us, I was so frustrated and felt like I was just throwing money away.. and in many ways I was. He is so thorough with the work he does and it's clear he's passionate about what he does, while taking great efforts to get us the results we're looking for. I look forward to working with Will and Endico Data Strategic long into the future and would recommend him to anyone looking who is looking for a high level of care and attention.

THE HOUSE RULES · II

Four rules, kept before the first handshake.

House law · Not marketing copy

No junior handoffs

The founder is on every account. From the first call to every report after.

No binding contracts

No binding contracts. Stay because the work is good, not because a document says you must.

You own everything

You own everything. Accounts, pixels, creative, audiences, websites, dashboards. Leave any time and take all of it with you.

One jeweler per trade area

We do not work with two jewelers in the same trade area. Signing locks your competitors out of this bench.

WHY JEWELERS · III

Built for how jewelry actually sells.

High-consideration · Trust-driven · Local

We do not work with two jewelers in the same trade area.

HOUSE LAW · ENDICO DATA STRATEGIC

Fine jewelry is a high-consideration purchase: an engagement, an anniversary, a milestone, decided a handful of times in a life. Trust settles it more than price, and trust is local, tied to the handful of other jewelers working the same trade area. Agencies built for ecommerce at large treat that as a footnote. This bench is built around it, one trade area at a time.
