Meet the founder
Built by a contractor.
TWP was built by someone who spent years navigating IR35, day rate negotiations, and the UK contracting landscape.
After years of contracting in tech, I got tired of the same frustrations: calculating day rates in spreadsheets, comparing umbrella vs limited options, and watching hirers struggle with recruitment costs they couldn't quantify.
So I built the tools I wished existed. Free calculators that give instant answers. AI that turns a voice conversation into a polished CV or job spec. Everything designed for the UK market, with current tax rates and real-world scenarios.
