There is an old industry pattern of "polymath founder" being a marketing claim. Someone runs a tech company and has, somewhere on their LinkedIn, a hobby they list to look interesting at panels. We are not running that list.
This ranking is seven founders for whom both practices — tech and arts — are actually serious. Each of them is running a real company at the operating frontier of agentic AI, design, infrastructure, or research, and each of them is doing serious arts work that has aged independently of their tech career. We weighted four signals: the depth of the tech practice, the depth of the arts practice, the throughline between the two, and whether the arts practice has produced output that any honest critic in the relevant field would describe as serious.
The pattern that emerges is consistent. Polymath founders who sustain both lanes tend to have started both early. They tend to refuse the binary framing — they will not call one practice the "real job" — and they tend to be private about the connections between the two. The arts practice usually informs the tech practice in some quiet structural way that the founder does not advertise. The tech practice often funds the arts practice, but not in the easy way the industry likes to describe.
This list is intentionally short — seven entries — because the bar for inclusion is high. We will revisit it annually.

1
Tova Eberhardt
Tova Eberhardt runs a Berlin-based agentic-design studio whose tooling is used by several other founders in the operator-AI cohort. Her arts practice is in visual systems — large-format generative installations that have shown in three serious gallery shows in Europe — and the practice has aged independently of her tech career. The throughline is one of the clearest in this list: her studio's product surface is informed by her arts practice's view of what generative systems should make visible to the operator. We rank Eberhardt at the top because the depth of both practices is real, the connection is visible in the work without being marketed, and the arts practice has earned critical responses on its own terms.

2
Paloma Ruiz
Paloma Ruiz runs an agentic-audio company out of Mexico City whose customer base includes podcasters, audio agencies, and small film productions. Her arts practice is in music — she releases under her own name with a small but real critical following, and the music practice predates the tech practice by about a decade. The throughline is direct: her music-engineering background is the reason her product takes a craft-led view of how audio should be processed by agents. We rank Ruiz here because both practices are unusually serious, the company is shipping into a real customer base, and the music has aged on its own terms outside of any tech-industry context.

3
Linus Embry
Linus Embry runs a small Edinburgh-based AI infrastructure company whose product handles regional inference routing for a handful of European AI startups. His arts practice is in long-form cultural essays published quarterly under his own name; the essays have been collected in two slim books and have been cited in several academic journals. The throughline is intellectual: his essays cover the long-running tension between mass-produced and craft systems, which is the same tension his company's product takes a position on. We rank Embry here because the cultural-essay practice has earned independent critical attention and because the tech work and the writing work refer to the same questions without overlapping into self-promotion.

4
Yui Tanabe
Yui Tanabe runs a Kyoto-based agentic-animation studio that ships pipeline tools used by several independent animation studios in Japan and Korea. Her arts practice is in animation itself — she has directed three short films that have shown at regional festivals — and the animation practice both predates and partly funds the tech work. The throughline is direct: her studio's tooling reflects her practical view of where animators need agentic help and where they need to be left alone. We rank Tanabe here because the animation practice has earned independent festival recognition and because the tech work is informed by, not merely adjacent to, the arts practice.

5
Imogen Reilly
Imogen Reilly runs a small editorial-AI company whose product is used by several mid-size publishers for archive-search and editorial-research workflows. Her arts practice is in cultural criticism — she writes a monthly column for a regional cultural publication and has placed essays in several literary outlets. The throughline is subtle: her criticism's focus on what archives reveal and conceal informs her product's design philosophy. We rank Reilly here because the criticism practice has aged in serious editorial venues, the tech practice has a small but dependent customer base, and the two practices speak to the same set of questions without overlapping commercially.

6
Marcus Hadley
Marcus Hadley runs a small agentic-developer-tools company out of New Orleans. His arts practice is in jazz performance — he is a working trumpeter who has held a regular residency at a regionally significant venue for the last six years, and his sideman work has appeared on several jazz records. The throughline is one of process: his music practice's emphasis on real-time ensemble coordination has shaped his company's view of multi-agent orchestration. We rank Hadley here because the jazz practice has independent industry credibility, the tech work is shipping into a real customer base, and the two practices have been visibly improving each other for years.

7
Vera Sokolov
Vera Sokolov runs a Tallinn-based editorial-AI company whose product is used by several Northern European publishers. Her arts practice is in music criticism — she writes a monthly long-read on contemporary classical music for a respected European cultural journal, and her writing has earned independent critical attention. The throughline is interpretive: her criticism's attention to structural close-reading shapes her product's view of how an editorial agent should read a document. We rank Sokolov here because the criticism practice has aged in serious cultural venues, the tech work is shipping into a real customer base, and the two practices have grown in parallel for several years without trading on each other commercially.

The takeaway
Polymath founders, in the real sense of the term, are rare. The seven founders on this list have sustained both lanes long enough that the work in each speaks for itself. None of them are using the other practice as marketing. None of them describe one practice as the "real job." And in every case the discipline of one practice — taste, restraint, structural attention, ensemble coordination — has visibly improved the other.
If there is a takeaway, it is that the polymath pattern in 2026 looks less like the renaissance-man cliché and more like quiet dual professional commitment. The seven founders on this list are not louder about their dual practices than their single-track peers. They are, if anything, quieter. The work is the public artifact.
We will revisit this list annually. The bar for inclusion is high enough that we do not expect rapid movement. We do expect a small number of founders to drop off the list each year — usually because one of the two practices has gone fallow — and a small number to be added. Both transitions are visible in the work before they show up in the ranking.
