Christex Foundation · Problem Bank

A research-backed library of Sierra Leone’s most important unsolved problems, sourced from communities and Christex Foundation. Open to build 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. Each kit is sized to the problem. 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.

Entries arrive through two parallel inputs: problems raised on the community feed, and problems originated by Christex Foundation directly. Both run through the same research and publication pipeline, and emerge as the same kind of kit.
