RA 
Raz is a serial entrepreneur with a background in data systems and product development. He built CostLiving after identifying a consistent gap in the market: people making high-stakes relocation decisions based on cost data that was either paywalled, outdated, or impossible to compare across locations. He designed the underlying data architecture, the four-tier cost methodology, and the scoring model that powers every location page. He still reviews the methodology and output regularly.
