Who is Sunil Vallath?

I work as a product leader and founder. The line I use publicly is simple: I build products that make complex technology useful. The domains are fintech, digital assets and blockchain — places where the stack is sophisticated and the user still needs something clear, trustworthy and shippable.

This essay is the short version: present identity first, career chapters in order, and the through-line that connects them.

Present identity

My recent work has centered on company-building and product ownership in digital assets. At Lume I served as Co-Founder and CEO, leading product work in that space. Before that, at Sonic, I was Co-Founder and CEO focused on a decentralized exchange and token launches — connecting product strategy to go-to-market, not just shipping features into a vacuum.

Earlier, as Senior Product Owner at Input Output (IOHK / IOG), I owned product areas in the Cardano ecosystem, including work around Midnight Network — privacy-oriented products where wallet experience, DAO tooling and the underlying stack had to move together. At NEM Group I worked as a Product Strategist across the Catapult Mobile Wallet, Block Explorer and NEM Academy.

Those chapters share a pattern: roadmaps owned end to end, launches that had to survive real markets, and collaboration with counsel when regulatory constraints shaped what could ship. The craft is the same whether the surface is a mobile wallet, a privacy product or an exchange.

Earlier still, Exploride was a founder chapter — useful context, not the lead story.

I have co-founded companies, built products for global financial access, and helped blockchain projects bring new tokens to market. Across those roles I have owned roadmaps, led launches, managed product managers, and stayed close to the unpleasant details — localization, custody models, permissions, recovery — that decide whether a product is usable or merely impressive.

What “useful” means here

Complex technology is easy to admire and hard to adopt. A protocol can be elegant and still fail the first user who needs to move money, protect data or understand risk. My bias is toward products that close that gap — localized launches, clear defaults, interfaces that respect the depth underneath without forcing everyone to become an expert.

That is the through-line I want associated with my name: open access where it matters, honest product strategy, and shipping work that connects roadmap to distribution. If you are evaluating me for product leadership, that is the lens.

Useful is also a team standard. It means the product can be explained in one sentence, defended under scrutiny, and returned to without coaxing. Demos are cheap; trust surfaces — fees, confirmations, recovery, language — are where products earn keep.

Education and how I work

I studied product management at Carnegie Mellon (Tepper) and hold a B.S. in Computer Science from the University of Calicut. Formal training helps; so does having built under constraint — hardware timelines, protocol releases, wallet security, token launches. I am most useful where strategy, product management and go-to-market have to stay in the same room.

Practically, that looks like owning the narrative of a product as carefully as the backlog: what we ship, who it is for, which constraints we accept, and how the launch will be measured. I have little patience for roadmaps that ignore distribution, or for marketing that ignores what the product can actually deliver.
