Christex Foundation · Problem Bank

A research-backed library of Sierra Leone’s most important unsolved problems, sourced by Christex Foundation. Studied, documented, and currently building on.

Every entry in the Library is a problem that has been used, repeated, and validated against evidence. Each one is documented to the standard an investor, funder, or developer can build from. By the time a problem reaches the Library, it has already survived the field. The work of naming it, testing it, and writing it up is already done. What you see is the residue of the work before the work.

Not a hypothesis. Not a hunch. Researched.

Every entry carries the data to decide and build. The kit is sized to the research: some entries ship all six documents, others two or three. The floor is the same: enough evidence to act.

What a kit can include.
01Concept Note

The problem in plain language. Who, where, why now.

02PRD

Product requirements, scoped. What v1 ships, what comes after.

03Technical Design

Architecture, data model, integrations. Reviewed by engineers.

04Wireframes

User flows, screen by screen. Ready to hand to a designer.

05Roadmap

Week one, month one, quarter one. Concrete milestones.

06Pitch Deck

The story, on slides. For funders and founding team.

And, where possible,an optional proof of concept.

The Library is built to fill from two doors: problems raised by the community, and problems Christex Foundation researches directly. Today, every entry comes from Christex research. As the community feed opens, problems raised there will run through the same pipeline and land on the same shelf.

Build. Ship.

The library is open. Start from the research that’s live today, not a blank page. More problems, and the kits that come with them, are landing entry by entry.

Christex Foundation researches each problem and builds the first proof. You take it further.
