Our Mission

Make the practice of science as open as its findings should be.

For the past century, science has had a structural problem: the people most likely to discover what comes next — curious young people — are also the least likely to have access to mentorship, equipment, lab time, or a venue to present their work. XTF exists to close that gap.

We do not believe a student in Lagos, Manila or La Paz is one drop of brilliance short of a student in Cambridge. We believe they're often one mentor, one piece of lab equipment, or one airfare short. So we built a foundation that delivers exactly those things — without strings, without IP claims, and without the pay-to-play architecture that has crept into too many "global" student competitions.

What we do

What we don't do

Why XTF

Three problems we were built to fix.

The student science ecosystem in 2019 was — in our reading — already broken in three specific ways. XTF is the operational answer to each one.

1 · Geographic asymmetry

The four largest student science competitions in the world were collectively held in three countries. We made XTF a single global pool, with travel funded for every finalist.

2 · The mentorship cliff

Most national programs end at the trophy. We built a Mentor Network that continues for two years after the competition closes — university applications, lab placements, research follow-up.

3 · IP capture

A surprising number of "free" competitions quietly take a share of student work. XTF's bylaws prohibit any claim to participant IP. We're audited annually on it.

Leadership

Board of Directors

XTF is governed by an unpaid, independent board of nine members serving staggered three-year terms. No more than three board members may be affiliated with the same institution. Board meeting minutes are published quarterly.

Mentor Network

1,200+ working scientists. Matched 1:1. Free for students.

Every team that advances past the first review round is matched with at least one XTF Mentor. Mentors commit to 8–15 hours of consultation between September and the Grand Finals. We screen, train and rotate them annually.

Who they are

PhD students, postdocs, professors, and industry engineers from 47 countries. About 35% are themselves XTF alumni.

How matching works

Teams self-describe their project. Our reviewers tag it on 14 dimensions (sub-track, method, stage, language). Mentors are auto-suggested; a coordinator confirms.

How to become one

Applications open every January. Mentors must be at least 2 years past their bachelor's, in a related field, and pass a youth-safeguarding check. Apply →

Seed Grants & Residencies

Money for the things scholarships rarely cover.

XTF seed grants are not academic scholarships. We don't pay tuition. We pay for the friction that actually stops young researchers — a microcontroller kit, three weeks of cloud compute, a one-way ticket to the lab that said yes.

TierFormWhat it coversOpen to
Builder Microgrant Hardware, software licenses, prototyping materials, lab consumables. Any registered team (rolling)
Compute Cloud credits Compute and storage on partner clouds; one-year terms. AI/ML and Quantum tracks (rolling)
Lab Residency Mid-tier grant + travel 2–8 weeks in a host lab, including travel and stipend. Shortlisted teams (annual cycle)
Continuation Grant Major continuation grant Post-competition follow-on to mature a finalist project. Finalists, by panel review

Educator Hub

Built so a teacher can run an XTF club on a Tuesday afternoon.

The XTF Open Curriculum is a CC BY-SA 4.0 library of modular teaching materials, designed for after-school clubs, STEM teachers and home-schoolers. No subscription, no login wall, no premium tier.

Each module includes a teacher guide, student workbook, slide deck, and an assessment rubric. Modules ship in English, Spanish, French, Mandarin, Arabic and Portuguese.

Browse the Curriculum

Eight tracks, each with 6–10 modules

  • AI & ML — from "what is a model" to fine-tuning small open-weights models
  • Climate & Sustainability — life-cycle analysis, carbon accounting, climate datasets
  • BioTech & Health — wet-lab safety, PCR, basic synthetic biology, open data
  • Robotics & Hardware — sensors, microcontrollers, control loops, CAD/CAM
  • Quantum & Computing — qubits in plain language, error correction, simulators
  • Space & Aerospace — orbital mechanics, CubeSat basics, remote sensing imagery
  • Cybersecurity & Privacy — threat models, cryptography, privacy by design
  • Social Innovation Tech — accessibility, ethics, deployment in real communities
Governance

How we stay independent.

Independence isn't a slogan; it's a set of bylaws. The short version:

History

From a single judging panel in Geneva to 61 countries.

  1. XTF is registered in Geneva

    An ad-hoc panel of seven researchers — frustrated by the lack of open student competitions — files for non-profit status. First call for projects goes out in June; 412 teams apply from 18 countries.

  2. A fully remote inaugural challenge

    The first XTF Grand Finals are held virtually. 24 finalist teams; first Grand Champion is a biosensor project from a public high school in Buenos Aires.

  3. Open Curriculum launches

    In partnership with Mozilla Foundation and EMBL-EBI, XTF publishes the first 18 modules of the Open Curriculum under CC BY-SA 4.0.

  4. XTF Proceedings begin publication

    The first volume of the XTF Proceedings is indexed by DOAJ; 38 student-led papers across the eight tracks.

  5. Crossing 50 countries

    XTF receives submissions from 54 countries, half of them low- or middle-income. Travel-funded finalists from 22 nations land in Geneva.

  6. Seventh edition · largest prize pool to date

    The 2026 Challenge is the largest in XTF's history, with eight tracks, three divisions and continuation grants for every finalist team.
