The problem
A price chart is hygiene. Guidance is position.

YOUR BRANDMissing from the apps they open
SAME PRICE. INTERCHANGEABLE BRAND.
01
Customers already get the spot price elsewhere.
A third-party chart does not carry your brand, your offers, or your relationship.
02
A number alone does not create a sales path.
Interest in saving rarely becomes a lead or a contract conversation inside a generic price app.
03
Building the real layer in-house is slow and risky:
optimisation, ledgers, scenarios, grid context, web, and mobile.
04
Without an owned interface, you rent attention.
Every open in someone else's app is brand and messaging you do not control.
Commodity price apps do not become the household’s energy interface. A branded guidance layer can.
The solution
An optimisation layerunder your brand.
OptiSähkö is not a widget and not a static brochure. It is a full product surface: live prices, a probabilistic estimate for the day after tomorrow, device-level timing, an immutable savings ledger, a Savings estimate for the home, investment scenarios with quote request, and live grid intelligence.
The web application is the core. iOS and Android are part of the white-label package. One brand, one deployment.

Little wind, price under upward pressure

Factors pushing the price up are clearly ahead
Wind is only 9 % of production, against a typical 15-20 %, so costlier balancing power sets the price.

Questions
Direct answers to the questions that usually remain.
Q1Is white-label real?PRODUCT SHAPE
Yes: brand, tokens, and copy. ONE BRAND PER DEPLOYMENT on standard tiers.
Q2Why web if there are apps?PRODUCT SHAPE
Web is the full core product and the diligence surface. iOS and Android extend distribution.
Q3Is the forecast tomorrow’s price?BOUNDARY
No. Tomorrow’s prices are published on the exchange the day before. The model estimate targets the DAY AFTER TOMORROW.
Q5What does setup include?COMMERCIAL TERM
Brand implementation, environment readiness, native package bootstrap, and launch onboarding per tier. Not a hollow fee.
Q6Is the pilot credited?COMMERCIAL TERM
Yes. The €5,500 pilot is FULLY CREDITED if you convert to STARTER, PROFESSIONAL, or ENTERPRISE WITHIN 30 DAYS of pilot end.
