Custom R&D · Prototypes · MVPs · POCs

From idea to working prototype, MVP or POC — in one team

Voltron builds prototypes, MVPs and proof-of-concepts end-to-end — custom electronics, embedded firmware and full-stack software in the same workshop. Batmobiles, LED installations, car dashboards on CAN bus / OBD-II, fleet trackers, on-set movie tech, ERPs, BMS + telemetry integration for sourced battery packs, medical sensors. For companies, artists, film crews and creatives.

PCB design and custom electronics prototype

PROTOTYPE · MVP · POC WORKFLOW

Discovery → Prototype → MVP → Production

Most custom projects fail because someone jumps straight to production before validating the idea. We do it the other way around, at each stage with an honest verdict:

  • Discovery — a real conversation about the problem. What does “working” actually mean? What must it survive?
  • Prototype / POC — typically 2–8 weeks. A proof-of-concept you can hold, drive, touch, or run — enough to answer “can this work at all?”
  • MVP — the first real, deployable version. Enough features to solve the actual problem and put in front of your first users or customers.
  • Production — hardening, documentation, spare-parts kit, training, ongoing support. Only if the MVP proved out.
  • Honest verdict at every step — kill, iterate, or scale. The prototype and MVP are yours either way.

👥

Who this is for

🎨

Artists, creatives, event producers

You have an idea for an interactive installation, a themed vehicle, a lighting piece or a custom prop. We build the electronics + software to make it work reliably in the real world.

🚗

Vehicle owners & garages

Custom conversions, restorations, fleet trackers and dashboard upgrades. If the vehicle has electricity in it, we can extend it.

📈

Startups & product founders

You want to validate a hardware or software idea before raising money or committing to production. We build the proof-of-concept end-to-end in 2–8 weeks so you know it actually works.

🏭

Established businesses

You have an internal workflow, a fleet, a legacy product line, or a new sensor idea that needs custom electronics + software. We design, deploy and support.

Applied AI

Applied AI — in-house, for your business

Not another chatbot. We build custom AI that lives inside your workflow — trained on your data, deployed on your infrastructure, and honest about what it can and cannot do.

Documents & data
OCR · classification · extraction

Invoices, offers, contracts — extract fields into your ERP instead of typing them.

Customer & sales
Product & support chatbots

Trained on your catalogue, docs and past tickets — not on the whole internet.

Sensors & ops
Predictive maintenance & anomaly detection

Time-series models on your BMS, motor or machine data — catch failures before they cost you.

Vision
QA inspection & counting

Camera + model at the production line for defects, counts and part identification.

Automation
Email & ticket triage

Auto-route incoming mail, extract action items, draft replies for humans to approve.

Voice & language
Speech → structured data

Voice notes to invoices, phone calls to CRM entries, multilingual pipelines.

Tell us what you need — we’ll draft a plan

Send us a short description of the workflow, decision or task you want AI to help with. Within a few days we send back a written plan: what data you already have, what model fits, integration approach, realistic timeline and honest cost estimate. If AI isn’t the right tool, we’ll tell you that too.

Honest note

We’re a small in-house engineering team, not a 500-person consultancy. That means: we take on projects where our hands-on hardware + firmware + software combination is actually needed. We don’t chase enterprise SaaS-only work, we don’t pretend to do smart-city deployments, and we don’t sell you a slide deck. If your project fits, we’ll say so. If it doesn’t, we’ll tell you that too and often point you to someone better.
