Electrical Engineers · Software · AI — one team, end to end
We build the software your operation runs on — and we’re the ones who answer the 3 a.m. page.
From the factory floor to the back office, X402 designs, builds and operates the systems your company runs on — with AI woven through every layer. We ship in weeks what agencies quote in months, and we stay on to run it in production.
- 4,073+industrial machines monitored across 21 factories, 3 countries
- 35,000+bank customers on stablecoin rails we built & run
- 24/7systems we run in production, never hand off
- 40 daysour last factory deployment — traditional integrators quoted 12–18 months
No pitch deck. Tell us what’s breaking — you get a straight, no-jargon answer within a day.

We secured the systems first. Then we gave them AI.
Thirty years of information security and infrastructure management are why our AI can be trusted with real operations. Anyone can give an agent power; we know how to take it away. Because we build the core layer ourselves — networks, identity, storage — our agents get exactly the access they need and not one permission more, and your data stays protected from rogue automation, accidental deletion and unauthorized access alike.
An agent can only touch what its least-privilege credentials allow — and it cannot escalate. We build the cage before we build the agent because containment must be by construction, not by policy: segmented networks, scoped keys, zero standing access.
Immutable, locked backups that no automation — and no mistake — can erase. We design storage to survive rogue agents because we operate these systems in production — we’ve seen what bugs and runaway automation can do. If an agent goes rogue, the blast radius was drawn before it was deployed.
Every action an agent takes is attributable, logged and reviewable. We build the audit trail before the agent runs because trust without evidence is just hope — and hope doesn’t pass an audit. Ours comes with the trail built in.
The agent orbits its permitted scope. Any attempt to escalate hits the permission boundary and is blocked — containment is by construction, not policy.
Real systems. Running in production. We’re still the ones on call.
Every result below is live — not a demo, not a case study from a consulting deck. We built it, we operate it, and the client still calls us when something needs to change.
4,073 machines. Pilot live in 40 days.
Electrical engineers and software engineers on one team: real-time telemetry from circular-knitting machines on a factory floor, unified into the system that runs the entire operation — OEE, downtime, yield, all live.
See the case study → Financial rails3 banks. 35,000+ customers. Settlement in 3.4 seconds.
Stablecoin payment rails under three banks — direct government registry integration, instant settlement, and under $0.01 per transfer replacing wire fees that cut straight into margin.
See the case study → Zero-trust network6,000+ endpoints. Self-defending, active-active.
Private mesh across 3 datacenters — if one goes dark the others carry every tunnel automatically. Zero standing access, every action attributable, blast radius drawn before any agent deploys.
See the case study → Precision agriculture500+ drones. Not one pilot. 18,000 acres/day.
RTK GPS and computer vision driving fully autonomous field surveys — zero human pilots, zero missed passes. The client’s team watches the output on a dashboard while the fleet does the work.
See the case study → Enterprise campusWhen the membership expired, the door stopped opening.
Access control, network policy, and billing unified into one system. A single badge event cascades through all three simultaneously — no reconciliation, no staff intervention, no billing exceptions.

Six systems. All running right now.
Every number below is live — not a slide, not a historical average. This is what 24/7 operations looks like from the inside.
Blocks we're minting. Right now.
We operate one of the top block producers on a major public blockchain. We pull it straight from the public chain — refreshed every few minutes, and every row below is a real block our infrastructure produced.
What it takes to stay at the top.
Running one of a network's top block producers is the opposite of "spin up a node." It is a 24/7 operation where a single missed block is revenue gone and trust spent — so every layer is engineered for it.
Under 200ms, worldwide
A new block has under five seconds to reach every node on Earth or it gets orphaned. Ours typically propagate in under 200 milliseconds — which only happens with relays on multiple continents and tuned, low-latency peering.
Redundant, always
Redundant block-producing and relay nodes, hardened key handling, UPS-backed power and automated failover with instant cutover. Five minutes of downtime is measured in missed blocks and lost rewards.
Peered with the network
We coordinate directly with other major producers on topology, relays and connectivity. A healthy chain is shared infrastructure — block production is a team sport, not a solo node.
Watched every second
24/7 monitoring of slot timing, missed-slot rates, peers and chain density, with alerting and on-call response — problems on a producer have to be caught in seconds, not the next morning.
Upgrade & hard-fork ready
Coordinated node upgrades and hard-fork rehearsals across the operator community, staged and verified before every protocol change so we cross each transition without missing a block.
Stake that compounds
A producer only mints in proportion to the stake that trusts it. We run the delegator relations and marketing that attract stake and keep it — turning reliability into reputation into more stake.
Every team in your company deserves an AI co‑worker. We deploy them.
Your people still make the calls. AI agents handle what they’ve been doing manually — sourcing data, running checks, drafting outputs, flagging anomalies. We audit, deploy, and operate agents across every team that has repeatable decisions to make.
- Across every team Sales, finance, operations, compliance, marketing. We start with the team bleeding the most time on repeatable decisions — then expand.
- Your data stays inside When LGPD, GDPR, or your own policy requires it, agents run inside your infrastructure. We build for the constraint, not around it.
- Contained and audited Every agent has a defined scope, a human escalation path, and an audit trail built before it runs. Containment by construction, not policy.
- Operated in production We don’t hand you a deployment and leave. We run the agents, monitor performance, and improve them as your operations evolve.

Common questions
- What exactly does X402 build?
- Industrial control systems and factory-floor software, financial rails and payment infrastructure, AI agents for back-office automation, zero-trust security networks, and the custom integrations that tie all of it to your existing stack. We work end-to-end — hardware, firmware, backend, AI, dashboard.
- How quickly can you start?
- A working pilot is typically live within 40 days of scoping. That’s not a slide — that’s the factory case above, where 4,073 machines were in production in 40 days from kickoff.
- Do you operate what you build?
- Yes. Everything we architect, we can run — 24/7 under contract, with on-call response, monitoring, and maintenance. The documentation is real because we depend on it at 3 a.m. No handoff to a team who didn’t build it.
- What industries do you serve?
- Manufacturing, fintech, agribusiness, healthcare, logistics, professional services, and government-adjacent operations. If your business has regulatory filings, machine data, financial flows, or back-office processes — and you don’t have the engineering team to automate them — we’re probably the right call.
Let's work together.
Have systems that need an owner?
Tell us what you're running — or what keeps breaking — and we'll tell you honestly whether we can help. Replies come from a human, usually within a day.
“Every project I say yes to, I am personally responsible for. Not a team manager, not a senior engineer standing between you and the work — me. If something breaks at 3 a.m., that’s my phone. I built X402 around that commitment because it’s the only way I know how to build things worth operating.”

First messages look something like these.
Machine visibility — can you help?
“We have 140 injection-molding machines on our floor. Supervisor walks the floor every 2 hours for updates. I want real-time visibility — which machines are running, cycle counts, fault alerts. Is this the kind of system you build?”
Invoice processing — looking to automate
“We process around 4,000 invoices per month, all entered manually. I’ve been told 80% could be automated. We use an older ERP. Looking for someone who actually builds this — not just consults on it.”
AI for customer support — where to start?
“Our team handles 1,500 messaging app messages a week — mostly order status and billing questions. I want to build an AI agent for the routine ones. Don’t know what this costs or how long it takes. Can we talk?”
Shipment tracking — too many manual touches
“We have 400+ active shipments at any time and track them by calling the carrier or checking email. Three people spend half their day on this. I’ve seen systems that do it automatically — not sure what’s realistic for us. Is this your kind of problem?”
Pipeline lives in messaging app groups
“Our reps track leads in messaging apps and personal notebooks. I can’t see pipeline, forecast revenue, or know why deals died. I need something that works for a team that lives on their phones. Is that the kind of thing X402 builds?”
NF-e rejections — can we automate the fixes?
“We issue around 800 NF-e a week. About 40 get rejected by the tax authority — wrong field, late correction, weekend batch fails. Two people spend their mornings chasing rejections. I want automatic validation before submission and auto-retry on fixable errors. Do you build this?”
