About Flux Tailor

Data infrastructure for the energy transition.

Flux Tailor was founded in 2017 after years of deep utility data work and a growing recognition that the sector was missing something fundamental: the data structure and tools needed to make rate plan information usable, accurate, and transparent. While standards exist for customer usage data and grid operations, no comprehensive standard has existed for the rate plan data that determines how customers are charged. In 2025, Flux Tailor completed its pivot from consulting to a SaaS company, with UtiliPub™ as its core product and URPX as the open standard beneath it.

Flux Tailor LLC is a New York State certified Women Business Enterprise (WBE).
