Why we built Joulely

We’re a small team of quants. We normally spend our days modelling financial products, building forecasting systems and wrestling with big, multi-dimensional optimisation problems. We got fed up with a corner of the energy industry — and figured the same techniques we point at portfolios might help ordinary people get a fairer deal on their own bills.

• What we’re actually doing. Taking the methods we’d normally aim at markets — optimisation, forecasting, working from real data rather than averages — and turning them on your home. The question we care about: are you paying more than you need to, and what would genuinely change that?
• Free — and the catch. We want this to be free for everyone. But some of the data feeds that make it effortless to connect your home cost real money to run. So part of the job is funding those without bending the product — we’ll always be clear about how we make money, and the ranking is never for sale.
• As people find us. If visitors start arriving, we’ll study how the site gets used — anonymised, first-party only, no third-party trackers — purely to make the journey easier and more useful. Nothing about you is sold.
• No favourites. We don’t pick winners for anyone’s benefit but yours. The ranking follows your numbers, not our revenue.

That’s the whole idea: serious modelling, pointed at your home, kept free and straightforward. If it saves you money, tell a friend — that’s how we’d like to grow.
