Not every great idea is investable. Mindsheet helped Northstar Equity evaluate PinOptic — a genuinely elegant security innovation — and made the difficult but correct call: saying no, not because the technology was weak, but because the market had already made its choice.
A Solution You Want to Believe In
PinOptic was one of those ideas you want to succeed.
It replaced numeric PINs with memorable pictures and colours, dynamically changing the keypad layout every time. Shoulder surfing became pointless. Keypad cameras became useless. From a human point of view, it was intuitive and elegant — and when I tried it, I could recall the picture combinations effortlessly.
My heart said yes.
But this evaluation was for Northstar Equity, and hearts don’t make investment decisions — markets do.
The timing was the problem. PinOptic emerged just as the UK had finished rolling out Chip and PIN, a £1.1 billion national infrastructure investment involving 120 million cards, 850,000 terminals, and 1.5 million trained retail staff. The market had already paid the price of change and had zero appetite to do it again.
Our analysis showed that while PinOptic was technically superior in several dimensions, it only delivered a marginal improvement over the incumbent solution in the point-of-sale market — nowhere near enough to overcome entrenched behaviour, sunk costs, and standardisation pressures PinOptic evaluation.
Human factors mattered just as much as security metrics. Once people learn a skill at scale, they resist relearning it. We’re still using the QWERTY keyboard for exactly this reason — not because it’s optimal, but because the switching cost is intolerable.
The data reinforced the instinct. Focus groups showed no realistic path to rapid adoption. Even optimistic scenarios suggested five to seven years before meaningful traction — far beyond a viable venture horizon PinOptic evaluation.
So the recommendation was clear, and uncomfortable.
The idea was good.
The market was not ready.
And timing, not technology, killed the investment case.
When Markets Lock In
PinOptic was like inventing a better alphabet after the world had already learned to read. Technically superior, logically sound — but asking millions of people to relearn a basic skill they’d already mastered was never going to work.
The Decision That Matters
At Mindsheet, we don’t just assess whether an idea works — we assess whether it can win. That means understanding market inertia, human behaviour, timing, and adoption economics, not just clever technology.
If you need a clear-eyed investment or innovation decision — especially when the answer might be “no” — Mindsheet can help you avoid expensive mistakes before they happen.
