Antonio
Key.

Antonio Key is not waiting for the Series A deck. By the time most funds know a company exists, his wire has already cleared and the founder has his cell number.

That is the working position of Sunset Ventures, the pre-seed fund he co-founded and runs as General Partner from offices anchored in Los Angeles and San Francisco. The portfolio is the resume: more than seventy companies in roughly five years, including the avatar layer of the consumer internet (Ready Player Me), one of the most argued-about crypto franchises of the decade (Yuga Labs), the AI-assisted filmmaking studio acquired by Autodesk (Wonder Dynamics), the climate finance bet Flow Carbon, and the building-electrification builder BlocPower.

Sunset is a small fund. Antonio is a small-fund partner by choice. The thesis is plain: write early, write conviction, and stay close enough that the founder can call at 11 p.m. without checking which time zone you are in.

The first business Antonio built was not a fund. It was K.O.T. Marketing Group, an LA event marketing firm aimed at what the world would eventually decide to call millennials. K.O.T. ran the door, the room, and the after, and it ran them for the audience luxury brands later spent a decade trying to learn. He grew it into a multi-million dollar business while everyone else was still arguing about whether Facebook ads worked.

What that taught him is something most investors never get to learn firsthand: how to read a room of consumers who have not yet been named. Years later, that habit shows up in the portfolio. Sunset's bets cluster around companies that take a culture seriously before the culture is profitable - avatar marketplaces, creator tooling, healthcare interfaces designed for people who do not enjoy the word "patient," carbon software for builders, AI infrastructure for engineers who would rather not write a glue script ever again.

After K.O.T., Antonio got the institutional version of the same lesson. Deloitte management consulting. Then Wall Street, specifically Bank of America Merrill Lynch in New York, where he closed ten technology M&A transactions totaling roughly twenty-six billion dollars in enterprise value. The number is large enough to make a point and small enough to remember: ten deals, twenty-six billion. That is what it looks like when somebody learns the back end of the tech industry from the deal lawyers and the model builders, not the press releases.

Then Samsung Next. He started in corporate development - the team that quietly decides which startup gets acquired or partnered with across ad tech, IoT, digital health, and fintech - and graduated to Director of Investments on the venture side, where Samsung writes seed and Series A checks into software and services. It is the kind of seat that turns curious people into very specific people. Antonio came out of it convinced that the most interesting work happens about thirty-six months before the corporate development team ever hears of a company.

So he started Sunset.

The Sunset thesis, said plainly

Sunset is pre-seed. Sunset is sector-agnostic. Sunset is small on purpose. Those three sentences sound like a tagline, and in venture they almost always are. Antonio's version is operational. The fund has to be small because at pre-seed the only thing the GP can scale is attention. The fund has to be sector-agnostic because the founders worth backing at that stage do not arrive in a tidy sector folder. They arrive as a person who quit their job and is about to do something embarrassing on the way to being right.

The job, then, is to find that person, fund them quickly, introduce them to the next five conversations they need, and not get in the way. Antonio's investors keep funding him because he is unusually good at the first part and disciplined about the last.

Why diversity is in the operating manual

Antonio is a proud alum of Toigo, MLT, and the UCLA Anderson Riordan programs. He chairs the San Francisco chapter of Stanford's OVAL undergraduate admissions program and previously sat on the national board of the Stanford Black Alumni Association. These are not lapel pins. They are the calendar. He treats access to early-stage capital as a civic project rather than a marketing line, which is partly why the Sunset deal flow includes founders who would otherwise have to spend a year collecting warm intros.

This is a quiet thing about the way he works. Most investors talk about pipeline. Antonio builds it - through the Wharton Black Alumni community, through Kauffman, through years of being the person who answers a cold email from a stranger.
