After my freshman year, I interned at a small company in Texas that had the same business model as Utiliz. Send us your bill, we analyze your usage data and get you on the best plan. You split the savings with us.
Do NOT underestimate the energy bills in Texas... The average prices I saw were ~ $800. Obviously this was a luxury market, but your perception that people are spending 80-150 on energy is completey wrong. Not only that, but they are often far overspending from what they need to.
The problem with electricity deregulation is that every company is selling and reselling the same service, often even from the same plants. So the only differences are superficial pricing and marketing differences. Two customers living a mile apart, in similar size houses, using similar amounts of electricity, might be paying drastically different amounts of money.
When I got there, the processes were all manual... but I automated a bunch of it. The whole business is very automate-able, as it's just a matter of parsing .pdf electricity bills and comparing prices on the homepage.
