Sympify

Fueling Futures Foundation

It started as a reverse-dictionary prototype: instead of looking up a disease and finding its symptoms, start with the symptoms. It has since become an organisation with chapters in three countries. This page is not the organisation's pitch — it is what building it actually looked like.

Sympify.org explains what the organisation is and what it does, and the app itself lives at sympify.ai.

This page is the other half: what it was like to build, how it changed shape, and the parts that do not fit on an about page.

The starting problem

Sympify began as a small reverse-dictionary prototype: instead of starting with a disease name and looking up its symptoms, a user could start with symptoms and receive a list of conditions worth discussing further with a clinician. I built the early version while learning more computational work at USC.

The first prototype was useful mainly as a proof of concept — it could show that the interaction was possible, but it was not yet accurate, complete, or robust enough to be treated as a clinical tool.

Turning a prototype into a team

The project stopped being a solo prototype once other students began joining with very different interests. Some cared about research, some about coding, some about outreach, and some about building chapters at their own schools.

We eventually organized the group into research, technical, business, and chapter leadership structures so that people could contribute without everyone doing the same thing. Learning to build that structure was as important as building the software itself.

Growing beyond one school

Growth came mostly through students who wanted to build something locally rather than simply join a central online team. Chapters gave them room to organize events, recruit members, and adapt the mission to their own communities while staying connected to the larger organization.

The challenge was creating enough structure to keep the work coherent without turning every chapter into a copy of the same club.

Building a place for younger students to lead

Instead of keeping every decision at the founder level, Sympify developed multiple layers of responsibility across departments, directors, chapter leaders, and local members. The goal was to make it possible for a new member to start with a concrete task, grow into ownership of a project, and eventually lead other students.

That structure also forced me to learn a harder version of delegation: giving someone enough context to make decisions without requiring them to ask me about every detail.

About the numbers

The figures on this page — 70+ members, 8 chapters, $55,000+, 8,520+ hours — are organisation-wide. 8,520+ hours is the total service contributed across Sympify, not Jalen’s personal hours, and the $55,000+ is organisation-wide funding rather than money raised personally.

Hours are reported by each member and by the director directly above them, which is what makes the total verifiable.

↳Milestones

  1. Building the First Sympify Prototype

    A small reverse-dictionary prototype: start with symptoms, get back a list of conditions worth discussing with a clinician. Useful mainly as proof that the interaction was possible — not yet accurate or robust enough to be trusted.

    Chapter
    • Add early screenshots or mockups
  2. Turning a Prototype into a Team

    Other students started joining with very different interests — research, coding, outreach, chapters — and the group had to be organised so that people could contribute without everyone doing the same thing.

    Taking Sympify to the Congressional App Challenge

    Sympify was recognised with the Community Impact Award for California's 38th District. The Certificate of Special Congressional Recognition, signed by Rep. Linda T. Sánchez, was presented at the district's award ceremony and is dated 30 January 2025.

    • Add the official announcement link
  4. Health Awareness Events: From an App to Actual Conversations

    Running events in person, where the value was less the software and more the conversations it started.

    Chapter
    • Add individual event names
    • Add photographs
  5. Growing Sympify Beyond One School

    70+ members, 8 chapters, 8 schools, 3 states, 3 countries — grown mostly through students who wanted to build something locally rather than join a central online team.

    Chapter
    • Add a chapter map or list once chapter names are approved for public use
  6. Working with Hospitals and Clinics

    Collaborations with four hospitals and clinics.

    Chapter
    • Add approved organisation/partner names and links (not listed on the sympify.org landing page)
  7. Raising Over $55,000 for the Mission

    The organisation has raised more than $55,000 in total support. This is organisation-wide funding, not money raised personally by Jalen.

    Chapter
    • Add the major fundraising channels
    • Note whether any portion was restricted for specific programmes
    • Add a public-safe breakdown of how the funds were used
  8. 8,520+ Hours, but What Were We Actually Doing?

    Community outreach, health-awareness events, chapter activities, research, technical development, organisational operations and other approved service work — reported by each member and their director, so the total can be verified. Organisation-wide, not Jalen's personal total.

    Chapter
    • Add an approximate breakdown by category if one exists
    • Confirm whether all technical/research hours qualify as volunteer service under the same accounting method
  9. Building a Place for Younger Students to Lead

    Departments, directors, chapter leaders and local members — so a new member can start with a concrete task, grow into owning a project, and eventually lead other students.

    Chapter
  10. Sympify Goes International

    Sympify expanded beyond the United States through international student chapters and community work, including activity in China.

    Chapter
    • Add approved chapter and city names
    • Add event names
    • Add international chapter photographs and captions
    • Add current international impact figures to display
