We turn
complexity
into clean systems.

Legacy Logik is a small, AI-assisted SaaS studio. We design, build, and run lean B2B software for operators who have a real problem to solve and no engineering team to throw at it. We work across sectors and go deepest where the numbers have to be right: real estate and property.

What we do

A few things
we're shipping.

A snapshot of current work, not the limit of what we'll take on. Today: a custom-build practice and a validated product live in production with real estate teams. Bring us a B2B software problem that doesn't fit cleanly into either, and we'll still scope it.

SVC · 01: custom build

Custom SaaS development.
Scope to ship, fully documented.

We take B2B software problems from zero to a deployed product. Every engagement begins with a defined scope, moves through a documented architecture phase, and builds at a controlled cadence.

PRD · 01: validated

White-label ROI platform.

A branded, embeddable ROI calculator for real estate developers and sales orgs. Models pre-construction and resale scenarios. Live in production at AMARI Tulum.

REF · how we work

Proof, not promises.

We run it before you do. Every product is built and validated in our own production environment before it reaches a single one of your customers. Disciplined, documented, and built to outlast the handoff.

REF · operating thesis

Disciplined, not fast-and-loose.

Every decision logged. Every phase gated. Every system documented. The same discipline that ships our own products is the discipline we bring to yours.

// how we build

A structured pipeline.
Five phases. Every project.

Click a phase. Every Legacy Logik engagement moves through these five stages: scoped before we build, validated before we ship.

01Scope+
Defined intake. We start with a written scope, a problem statement, and a constraint map. Nothing leaves this phase without sign-off.
02Architecture+
Stack picked, data model drawn, decision log started. Architecture is documented and approved before any code is written.
03Build+
Phased implementation in reviewed cadences. Every change is reviewed and gated before the next phase begins.
04Validate+
QA matrix run before any handoff. We deploy to a Legacy Logik production environment and run the product ourselves first.
05Operate+
Documented handoff with runbooks, ops dashboards, and on-call protocols. The system survives without us in the room.

AMARI Tulum: a dual-scenario ROI builder for pre-construction and resale villas.

Buyers were drowning in static PDFs and inconsistent calculations. We shipped a branded, white-labeled tool that turns complex investment projections into shareable, presentation-quality scenarios.

operating thesis

A small team can outbuild a department:
if the system holds.

Legacy Logik was founded on the idea that a small, disciplined team with the right systems can build and operate a portfolio of scalable software products, without the cost, complexity, or overhead of a traditional development organization.

Avoidcomplexity. Simplicity compounds.
Documenteverything. Systems outlast memory.
Validatebefore it ships. Nothing reaches your customers unreviewed.
