American company. For businesses too specialized for off-the-shelf platforms. We've built it, operated it, and proven it works.

Generic platforms
don't fit
specific businesses.

Automation is hard. Off-the-shelf tools weren't built for dive operations, tour logistics, multi-region travel, or Dominican tax compliance. Your business has unique rules. Your infrastructure should too.

Domain complexity

Certifications, regulations, operational workflows — generic tools miss what matters.

Integration debt

Stitching incompatible platforms creates fragile, expensive-to-maintain systems.

Scaling friction

What works for one location or one team breaks when you grow.

Two paths.
One outcome.

We engineer custom infrastructure from scratch, or we deploy TADR — our proven multi-tenant platform. Either way, you get a business that runs itself.

Custom Build

Built for your exact domain

When your business is genuinely unique — specific regulations, unusual workflows, niche compliance — we engineer from first principles.

Purpose-built for your domain logic
No compromise on edge cases
CEBA Scuba is proof it works
You own the infrastructure
TADR Platform

Proven platform, fast deployment

Multi-tenant SaaS built specifically for travel and tourism businesses. Already running BlackBeards Tours and Zona Sur Travel as live tenants.

We help foreign businesses
operate inside America.

Two of the hardest problems for international operators: getting paid in the U.S. system and establishing a legal presence. We solve both.

U.S. Payments

Accept U.S. payments from anywhere

Foreign businesses lose revenue because they can't plug into the American payment system. We bridge that gap — so your customers pay in USD through familiar U.S. processors, and the money flows to you cleanly.

U.S. payment processor integration
USD collection for foreign operators
Stripe, PayPal, and ACH-compatible
Already running across our businesses
U.S. LLC Formation

Build your American entity

We help foreign individuals and companies establish a legal U.S. business presence — an LLC that unlocks American banking, payment processors, contracts, and credibility in the world's largest market.

LLC formation for foreign founders
U.S. banking access
EIN registration support
Designed for minimal overhead

We built it.
We operate it.

These aren't client stories. These are businesses we built and run. The infrastructure is live. The results are real.

Scuba Tourism · Custom Build

CEBA
Scuba

Scuba tourism. Engineered for complexity.

The challenge

Existing software comes with expensive subscriptions and is nearly impossible to modify. With CEBA, we engineered the entire system from scratch — and the client owns it outright. No recurring license, no vendor limits.

What we built

A custom operations dashboard handling the full complexity: booking management, certification tracking, equipment inventory, digital waiver signing, customer profiles, and calendar coordination across multiple dive sites.

"This is what we engineered for a specialized vertical. Every domain has this level of complexity. We know how to build for it."
Travel & Tours · TADR Platform

BlackBeards
Tours

Travel operations. Automated and profitable.

The challenge

Tour operations need seamless booking flows, real-time availability, customer communication, DGII compliance, and revenue optimization — working together, not stitched apart.

What we built

Deployed on TADR with custom tenant configuration: automated booking pipeline, customer management, multi-language support, DGII fiscal engine, and integrated analytics dashboard.

"Custom infrastructure built for travel operations. Repeatable at scale. BlackBeards was proof of concept. TADR is the platform."
Multi-Region Travel · TADR Platform

Zona Sur
Travel

Travel scaled across markets.

The challenge

Operating travel across different geographic regions means localized pricing, market-specific offerings, regional customer expectations, and separate compliance requirements — all under one operation.

What we built

Multi-tenant TADR deployment with regional configuration: localized product catalogs, market-specific pricing, independent tenant management, and cross-region analytics.

"We scale specialized infrastructure across markets. Zona Sur showed TADR can support geographic expansion without rebuilding from scratch."
