01 · Challenge
Krestline introduces investors to pan-African infrastructure and energy projects in the $5M–$50M range. Deals involve confidential documents, many parties and a facilitator who has to prove who saw what, and when.
Email threads and shared folders could not enforce NDAs, separate parties, or produce an audit record that would stand up to scrutiny.
02 · Approach
We built one application covering the marketing site, public intake for investors and project owners, a facilitator admin and the full deal pipeline. Investors and project owners get their own portal with invitations, search and notifications.
Each deal gets a room with private threads, an NDA gate before anything is shown, live message delivery and a hash-chained message log, so any tampering is detectable. Every data access goes through a single permission-checked layer, backed by a CI-blocking authorisation test suite.

What shipped
Key capabilities.
01
Deal pipeline
Facilitator view of every opportunity from intake to close, with search and notifications.
02
NDA-gated deal rooms
Nothing confidential is visible until the NDA is accepted. Private threads per party.
03
Verifiable message chain
Messages are hash-chained so any alteration of the record can be detected.
04
Investor & owner portal
Invitations, password reset, deal access and live updates for each party.
05
Permission-first data layer
Every read or write takes the acting user as a required argument; the database client is never imported anywhere else.
06
Authorisation test suite
Negative-case tests that block CI, plus append-only and hash-chain integrity tests.
