Building AI productspeople can use.

AI can generate an answer. The hard part is connecting it to messy data, real tools, and the decisions people need to make.

One person,
the whole product

From the first idea through design, engineering, and launch, I build the whole product.

About

I'm Nitai Aharoni, a product builder and software engineer in Israel.

I build products for property research with Tesse, hiring assessments with Bloom, grocery price comparisons with SuperMCP, browser tools for AI with Reflex, and home services with Handi. From the first idea through design, engineering, and launch, I build the whole product.

I've spent over ten years building software. At Oobit I led a 12-person engineering team and rebuilt the backend while 100,000 people kept using the product. Before that I led a team at Fireblocks and worked at Dynamic Yield and SAP.

I'm in Israel, so European hours overlap fully and US mornings still work. I have an EU passport too.
