What We Build
Not a consultancy. Not a reseller. A full-stack engineering team — electrical engineers, software engineers, AI engineers — that ships working systems and answers the 3 a.m. page.
Every engagement draws on the full stack — hardware, firmware, backend, AI, and ops. We don't hand off. We own it.
We build bespoke platforms end to end — ERP integrations that talk to legacy systems without ripping them out, custom operational dashboards with real-time data pipelines, and managed hosting that keeps everything alive after launch. You describe the workflow; we close the loop.
Autonomous agents for back-office workflows, customer operations, document processing, and government filings. We replace 3–5 FTE workflows with an agent that runs 24/7, escalates edge cases to humans, and gets smarter over time. No off-the-shelf chatbot — purpose-built systems that touch your real data.
Custom hardware, firmware, and software to wire industrial equipment of any age into a unified live view. Electrical engineers on payroll mean we handle opto-isolation, PoE device fleets, and encrypted mesh networks — not just the software layer. We've done this across 21 factories in 3 countries.
Machine-to-machine payments over Pix, open-protocol HTTP payment flows, stablecoin settlement, and full Brazilian tax and registry integration — NF-e, SEFAZ, and open banking APIs. We've built and operated payment infrastructure at scale for banks, marketplaces, and industrial platforms.
Six categories of problem. Systems running in production today. Different industries, same discipline: X402 ships what others spec.
Most vendors own one layer and subcontract the rest. We own all five — from the circuit board to the operations screen. Zero dependencies on third-party platforms. Zero finger-pointing when something breaks.
When something fails at 3 a.m., the same engineers who designed the circuit board pick up the phone. Zero subcontractors. Zero handoffs. Zero finger-pointing.
Four phases. One continuous commitment. We don't disappear after deployment.
We scope your problem in a structured discovery session, then ship a working pilot within 40 days — hardware and all.
We connect the pilot to your existing systems — ERPs, government APIs, machinery, payment rails — into one live data layer.
We hand your team the tools to use and monitor the system confidently, with dashboards, runbooks, and a direct line to our engineers.
We stay on as the engineering team that owns uptime, iterates on the system, and answers the 3 a.m. alert so you don't have to.
We work with decision-makers who have a problem technology can solve but lack the specialized team to build it.
Machine visibility, OEE tracking, and quality systems for factories of any age.
Fleet telemetry, warehouse ops, and real-time shipment visibility end to end.
Patient data flows, compliance automation, and connected medical device monitoring.
Payment rails, open banking integrations, and regulatory reporting on Pix and beyond.
Inventory systems, loyalty platforms, and checkout flows that scale without breaking.
SEFAZ, open data APIs, and interoperability with Brazilian federal and state registries.
Sensor networks, precision irrigation controls, and harvest-to-export traceability systems.
Document automation, client portal systems, and billing integrations that cut admin overhead.
Senior engineers take six months to hire, three to onboard, and leave when the next company offers more. The institutional knowledge leaves with them. X402 is already running — fully staffed, answerable at 3 a.m., and accountable for the system after the project ends. No ramp-up time. No attrition risk.
Agencies scope for months and hand you a deliverable. We scope in days and have a pilot live in 40 — that’s a commitment, not a goal, backed by the factory case that went from first call to commissioning in exactly that window. Then we stay: operating, monitoring, and improving the system we built.
If the platform existed, you’d already be using it. The problems we solve are the ones no vendor product covers: the integration between your circular-knitting machines and your operations dashboard, the compliance engine that knows Brazilian tax law, the rail that settles cross-border payments in 3.4 seconds. Custom, because generic doesn’t fit.
An API wrapper on a single commercial model breaks when the vendor changes pricing, can’t handle LGPD-sensitive data, and has no industrial context. We build the orchestration layer — running frontier models for complex reasoning, local LLMs on our own GPUs for sensitive data, and open-source models where cost and latency demand it. We own the whole stack. You don’t depend on a vendor.
No retainer, no pitch deck, no months of scoping. Here's exactly what working with X402 looks like.
One call to hear the problem. A technical walkthrough of what's possible and what's not. An honest assessment — within 48 hours of our first conversation, no invoice attached.
Weekly working software, not quarterly slide decks. Your team sees the system take shape in real time — with direct access to the engineers building it.
We don't hand off. We stay on — monitoring, maintaining, and improving the system as your operation grows. Your team can take over at any point; the runbooks travel with the code.
Describe the problem — we'll give you an honest assessment within a day. No pitch, no deck, no retainer required.
