Seth presenting PageMD on stage at the STARTedUP Challenge

Sebastian “Seth” Donea

Hi, I’m Sebastian, but my friends call me Seth (and if you’ve read this far I’d consider us friends (yes, the bar is that low)). I’m currently a Senior at Signature School (we just ranked #2 again!!! USNews) in Evansville, IN. If you don’t know where that is, start by closing your eyes, then imagine the shape of Indiana, that sort of Y-like structure. Evansville is on that very bottom left tip. A beautiful place to fly over on the way to somewhere more stimulating.

I’m interested in Entrepreneurship and Finance, particularly within the Healthcare space. I grew up in and around the hospital–my mom’s a doctor–meaning I’ve seen a lot of the issues and inefficiencies that plague the system. I would’ve probably gone into medicine myself if my friend Yuto hadn’t convinced me to try a pitch competition. I fell in love with solving problems for the people I care about. Seeing the look on someone’s face when you take a chip off their shoulder is a feeling I’ll always chase.

There’s more to my story, but now I’ll give you the opportunity (you’re welcome) to discover it yourself. Below, I’ve recreated my actual room in Evansville, Indiana. Most of what I'm working on is somewhere in it. As Dostoevsky said, “Show me your room, and I will tell you exactly who you are.” Look around, I’m sure you’ll find something interesting.

The plain version

  1. PageMD

    Founder · the pager on the nightstand

    An AI agent that triages inbound calls and pages on-call staff at outpatient clinics. My mom is a doctor and her pager kept interrupting dinner. Doctors can't be taken out of the loop, so we build for the nurses and staff on the other end.

    I lead a 3-person team; we're in beta at 2 clinics in Vanderburgh County. 1st at regionals, 3rd of 1,174 at the STARTedUP Challenge final, $5,500 in funding ·pagemd.ai

  2. Holomap

    Builder · the glowing chart above the bed

    A straight line is the shortest way across the sea, but rarely the cheapest. Holomap pulls today's ocean currents, the 16-day wind forecast and live ship positions, draws them on a glowing tactical table, and plans the route that spends the least fuel.

    Every day a GitHub Action runs the planner on 58 trips off the US East Coast and posts the biggest saving. holomap-eight.vercel.app

  3. Dove

    Builder · the drone flying around the room

    A drone that works as a police officer's sidekick: it keeps eyes on a subject so nobody goes in blind, and it decides nothing about people. Tell it "follow the person in the red hoodie" and it finds them with its own camera, follows from 20–30 m, searches when they duck behind a building, picks them back up, and flies home on command. No face recognition; it only knows people by what they're wearing.

    Simulation only so far: a PX4 autopilot in Gazebo, YOLO tracking, and a safety supervisor that every command passes through. In the scored demo it found the target again 7 seconds after losing them, with zero safety violations. dove-kohl.vercel.app

  4. Field Dex

    Builder · the cards on the bed

    Enter a US ZIP code and every species people logged on iNaturalist within 10 km this week becomes a collectible card, rarest first. The dove on your feeder is Common; the fly someone photographed down the road might be one of a few hundred ever logged.

    Every evening a GitHub Action posts the rarest find near Evansville. fielddex-delta.vercel.app

  5. Helping Hands

    Developer · the trophy on the TV stand

    Community service runs on paper and trust. Volunteers find shifts, organizations confirm hours in a two-step handshake, and every hour ends up on a signed record.

    The team won the University of Evansville High School Changemaker Challenge (champion, full-tuition prize), then brought me on to build the website and platform. helping-hands-mu.vercel.app

  6. Send Energy

    Operator · the jar by the lava lamp

    Pre-workout gummies. I built the store and a custom checkout myself, and it has taken live payments since August 2026.

  7. Honors

    The medals on the wall by the bed
    • National Merit Scholarship Semifinalist
    • Morehead-Cain Nominee (1 of 2 school nominees)
    • Presidential Scholars Nominee (1 of 2 school nominees)

  8. Alumni Mentoring

    Founder · Signature School · the pennant by the hutch

    My school had no alumni network, so I started one. I recruit mentors, match them with current students, and track check-ins. 22 pairs and about 100 mentoring hours so far.

  9. Circular Venture Lab

    Intern since June 2025 · the lanyard on the door

    Wrote the CultivatID healthcare talent pipeline strategy: a 20-question intake form, 4 benchmarked state programs, and 8 retention strategies. To keep going through senior year, I got my school to bring back an internship course it hadn't offered since 2003.

  10. Does a knowledge graph actually help?

    Research, starting fall 2026 · the monitor

    Every "company brain" assumes a knowledge graph makes AI answers better. I'm measuring it: hybrid retrieval vs GraphRAG on the Rust RFC corpus, with questions I write by hand. If the graph doesn't help, that's the finding.

  11. Does private equity make dental care worse?

    Research · the books at the foot of the bed

    For my IB Extended Essay I coded 300 patient reviews across PE-owned and independent dental practices. Continuity of care dropped significantly at the acquired ones.

  12. Mock Trial

    Captain · the certificate by the TV

    Outstanding Witness from the Indiana State Bar Association. I run case strategy and witness prep, and took the team to state, where we placed top 20.

  13. Indiana Youth and Government

    Governor's Cabinet · the ribbons on the wall

    Wrote a bill that passed both chambers and was signed by the Youth Governor, which about 10 of 150 bills do. Appointed to the 4-person Governor's Cabinet from about 20 applicants.

  14. Tutoring

    SAT & AP Physics 1 · Elite Tutoring Place · the books on the gaming chair

    I diagnose gaps from practice tests, write study plans, and retest weekly. 9 students, average gain of 186 SAT points.

  15. Skateboarding

    Outside of work · the board on the floor

    I skateboard two or three times a week if I have the time. I'm still learning. Landed my first pop shove-it recently.

  16. Table Tennis

    Outside of work · the paddle on the floor

    I love table tennis. Currently running a STIGA Cybershape Eclipse. HMU for a 1v1.

Outside of work I also play League of Legends (Pyke main), and I speak conversational Romanian and French.
