PROFILE OVERVIEW
Editorial Brief
Hayyan builds products for people who participate in financial markets — and then runs them.
He co-founded SwapNet, a Telegram-native crypto exchange, and led it as CEO for roughly two years after launch. The product reached around 200,000 users on a simple bet: a familiar chat interface removes most of the friction of buying and swapping crypto. A separate automated product he built reached around 130,000.
Across seven years in the sector — crypto exchanges, payment platforms, proprietary trading — his work sits on the line between product and growth, because on a trading platform that line barely exists. The onboarding flow is the campaign. The fee structure is the positioning. Simplifying a transaction that used to take six steps does more for acquisition than the campaign promoting it.
At Sigma he works on exchange and broker growth, KOL and influencer distribution, and the partnership structures that connect them.

QUOTE / PERSONAL NOTE
The best growth work on a trading platform usually looks like product work. If people are dropping off at verification, no campaign fixes that.
I don't work around financial markets — I build products for the people in them.
Most crypto products ask users to learn a new interface first. The ones that grow meet people where they already are.
