Investment Thesis

MAF II targets a 35 / 35 / 30 capital deployment split across three thesis pillars. Every opportunity in the pipeline is mapped to one of these buckets to ensure thesis discipline and portfolio balance.

Target geography: East and Southern Africa, consistent growers (Kenya, Tanzania, Rwanda, Uganda, Ethiopia) and recent accelerators (Zimbabwe, Mozambique, DRC), with selective post-conflict exposure where Maris has on-the-ground operating capability.

The Maris Opportunity Screener

Every opportunity is evaluated through Maris's proprietary 11-criterion screening framework before any capital commitment is contemplated.

Eleven assessment criteria

Verdict bands

Each opportunity is scored across the 11 criteria, weighted, and converted to a percentage that maps to one of three verdict bands:

Pipeline by Investment Thesis

Use the tabs to filter the geography map and the deal scoreboard by thesis. Click any deal row for the one-pager; click any country count for a thesis-by-country breakdown.

Pipeline geography

Active-book opportunities by country. Country shading scales with deal count; hover the map for the country name, click a number in the table for the thesis breakdown.

Deal scoreboard

Sorted Advance, then Hold, then Discard; tie-broken by Phase 1 score. Click any column to re-sort, click any row for the one-pager.
