FOUNDER & PRODUCT BUILDER

Sina Estavi I turn ideas
into products.

Working across AI, fintech, software and digital culture — turning complexity into clear, useful experiences.

NOW / LONDON

Build beyond the moment.

For me, building begins with a question: what still does not work the way it should? Sometimes the answer is a new product. Sometimes it is a clearer workflow, a simpler experience or a way of turning complex technology into something people can actually use.

My work has moved across blockchain, digital-asset infrastructure, artificial intelligence, visual creation and content operations. What connects these projects is not one technology but a way of thinking: understand the problem precisely, make the solution usable and let its value prove itself over time.

This website is the official home of my work, writing and professional journey — a clear record of what I have built, what I am building now and the questions shaping what comes next.

SELECTED WORK

Technology matters when it becomes useful.

DOCUMENTARY RECORD / CRYPTOLAND & BRG

When the story is incomplete, the evidence must be visible.

Iran International reported — citing court documents, a court-appointed expert’s report, blockchain records, video and audio — that more than 2.4 billion BRG were sold after my arrest, estimating the value above $21 million. The new record separates documents, reported findings, first-person account and evidentiary limits.
