Hardware & Software Engineering
Architecture, component selection, firmware, embedded systems and full-stack software — the disciplines that meet where the physical and digital worlds touch.

Idea → Prototype → Product.
Then to market.
WIPLash Limited helps founders and product teams turn ambitious technology into shipped, sellable products — de-risking the journey from first sketch, to factory gate, to go-live.

// WHAT I DO
End-to-end technology consulting
Five ways I help teams get from "what if" to "shipped" — engage for one, or for the whole journey.
AI & IoT
From sensor to insight: connected devices, edge AI, data pipelines and LLM integration — designed to survive contact with the real world, not just the demo.
Idea → Prototype → Product
Structured de-risking: feasibility studies, rapid prototyping, design-for-manufacture, certification prep and the long climb from working demo to production unit.
Go-to-Market Strategy
Positioning, pricing, channels and launch plans for deep-tech products — the ones that need explaining before they get bought.
Startup Operations
Running the machine: fundraising prep, technical hiring, supplier and factory management, and building process without killing pace.

Book a call// HOW WE WORK
A path, not a guessing game
01
Discover
Pin down the problem, the constraints and the fastest way to prove the concept is sound.
02
Prototype
Build the risky parts first. Get something tangible in hands fast, and let it argue with the assumptions.
03
Productise
Engineering for the real world: reliability, manufacturability, certification and cost.
04
Launch
Position, price and route to market — then an operating rhythm that keeps the ship moving.
de-risk early. build honestly. ship deliberately.
// ABOUT
Hands-on, not slideware
WIPLash Limited is Sean Greenhalgh — a Hong Kong-based technology director, entrepreneur and start-up advisor with 15+ years in early-stage start-ups. As founder and CEO/CTO of TimeChi he took a smart hardware product from napkin sketch to a TIME Magazine Top 100 Invention of 2021, raising USD $450k from crowd and private investors along the way. As co-founder and CEO/CTO of Angelflow he now builds AI-powered platforms for the investment world. He has stood where you are standing: ideation, prototype, production, launch.
The consulting spans the full stack of building things: embedded C/C++ and PCB design in Altium and KiCad, CAD plus CNC and 3D-print prototyping, applied AI from TensorFlow models to production LLM systems deployed on Azure for a global luxury brand under NDA — and the commercial craft of pricing, positioning and channels. As founder of I'm New Media he took an unknown product to AUD $500k of sales in six months on a $100-a-week marketing budget. Advisor to three Australian start-ups, co-director of Startup Grind Sydney, founder of the OzHard hardware community: an engineer's judgement and an operator's pragmatism, not a 90-slide deck.
