Case Study · Built & Run by Lux

We built Dominican Bridge from zero. Same playbook we run for clients.

Newsletter, podcast, sold-out events across three cities, server-side conversion tracking, an authenticated member portal, and an AI-researched newsletter system. One brand, the full Lux stack, end to end.

Live numbers pulled from public profiles. Engagement averages 358 likes / 84 comments per post across the last 12.

Disclosure: Julio Lopez, founder of Lux, co-owns Dominican Bridge with a partner. We’re showing this case study because it’s the most complete picture of the Lux stack on a single brand. Every system below is one we deploy for clients.
The Brand
Dominican Bridge

A community brand built for repeat, in-person revenue.

Dominican Bridge is a community hub for the diaspora and internationals living in the Dominican Republic. Newsletter, podcast, member portal, and recurring events in Cabarete, Punta Cana, and Santo Domingo.

The business model needs the marketing stack to do three things well: pull cold attention online, convert it into a confirmed contact record, and fill seats at real events. Every system below was chosen to serve one of those three jobs.

The Stack

Seven systems. One brand. All of it transferable.

Each card below is a system we deploy for paying clients. Dominican Bridge happens to run all of them at once.

01 / SOCIAL

Organic social that produces revenue, not vanity.

We ran the content strategy and posting cadence that took the Instagram account from zero to 5.3k engaged followers, averaging 358 likes and 84 comments per post, and built a YouTube presence with 51.7k views and 575 subscribers in nine months. Reels are the engine. Every campaign maps to an event we need to fill.

02 / VISITOR IDENTIFICATION

We identify the Instagram handle behind anonymous landing-page traffic.

A Lux-built capability. When a visitor lands on the page from social, we resolve their identity back to the IG handle that sent them. Enriched contact records get scored, segmented in Mautic, and routed into the right follow-up sequence, without asking the visitor for anything.

03 / META CAPI

Server-side Meta CAPI with custom conversions and full value tracking.

Pixel-only attribution loses signal on iOS, on ad-block, and on anything that fires after the user leaves the site. We wired Dominican Bridge to Meta’s Conversions API server-side, with deduplication keys for every browser event, custom conversions per funnel stage, and monetary value passed on RSVPs and event registrations. Meta’s algorithm then bids against real downstream actions, not page views.

It’s the same tracking architecture we deployed for the Santa Monica History Museum to attribute fundraising revenue end-to-end during their digital campaign.

04 / INFLUENCERS

Creator partnerships added a secondary awareness layer on top of the ads.

The tickets were sold by the paid advertising we ran. To extend reach, we also identified relevant local creators, negotiated co-promotion terms, briefed them on the angle, and handled content approvals. Creators added a top-of-funnel awareness boost, but the conversions, RSVPs, and sell-outs were driven by the ad stack Lux built and operated.

CREATOR WORKFLOW
  1. Identify creators by audience overlap
  2. Negotiate co-promo terms
  3. Brief on event angle & CTA
  4. Approve content + track UTMs
  5. Attribute RSVPs server-side
05 / EVENTS

Every event filled. Every event sold out.

Events across Cabarete, Punta Cana, and Santo Domingo. Paid ads with proper CAPI signal did the selling, with creator content and newsletter announcements as supporting amplification and the portal’s RSVP system with location reveal handling conversion. Cold traffic to confirmed attendance, predictably enough that we sold every seat on every event.

06 / NEWSLETTER + AI AGENTS

A Mautic-powered newsletter where AI agents do the web research.

We built an automated newsletter system on top of Mautic. AI agents crawl the web for relevant signals (news, events, threads, listings), synthesize what matters, and assemble the next issue. A human approves the final draft. The result: a high-relevance newsletter at a fraction of the production cost, with full segmentation, drip campaigns, and confirmed-subscriber gating wired into the same database the portal authenticates against.

07 / PAID MEDIA + PORTAL

Ad placements, advanced bid structuring, and a custom member portal.

We handle Meta and Google ad placements with bid strategies structured around the custom conversions we defined, not the default platform events. The signal feeding the algorithm is the same downstream signal the business actually cares about. We also designed and built the authenticated member portal at dominicanbridge.com: magic-link auth, event RSVPs with reveal-on-RSVP location, guides, podcast hub, member spotlights, and admin tooling, all wired into the same CRM and analytics stack.

Dominican Bridge isn’t where our ad track record starts.

The ad stack that filled every event is the same one we’ve been running for clients for years. Three of them, in their own words:

“Your work on my AdWords campaigns has been invaluable. Having the flexibility to discuss things with you and put into practice only what I am comfortable with has been the biggest difference between other specialists.”

Dr. Bo Andel
Smart Pain Solutions

“Julio is a top notch Google partner for us. He is up to date on all the changes that Google constantly throws at you and is fast to respond to all our needs. Highly recommended.”

James Marshall Berry
Chief Strategy Officer, Wine and the Web

“Julio really did a great job with my SEO and Google Adwords. He increased my conversions for my medical practice. I saw many patients as a result of his marketing!”

Lawrence Silverberg

Why we’re showing you this

A case study from a client is a slide. A brand we run is the receipts.

Most agencies show you a logo wall and a dashboard screenshot. We’re showing you a live brand we built and operate: public Instagram, public YouTube, public portal, where every claim above is verifiable in the open web.

If your business needs any one of those seven systems, we already run all seven for ourselves. The work to deploy them for you is the same work, minus the part where we figured out what doesn’t work.

“We don’t pitch capabilities we haven’t run end-to-end. Dominican Bridge is how we keep that promise honest.”

— Julio Lopez, Founder, Lux Marketing
