Capital that lit cleaner kitchens

A celebration of early Signina Capital investors — and the DelAgua platform that carried Tubeho Neza to millions of rural Rwandan homes.

Investor legacy

From European belief to Rwandan hearths

Early Signina Capital investors backed a thesis that patient capital could seed climate and health infrastructure at household scale.

That bet helped build the platform behind DelAgua’s Tubeho Neza programme — free, high-performance Rwanda cookstoves for rural families who could never have bought clean cooking hardware over school fees or healthcare.

Today the story is measured in cleaner air, lighter fuel loads, protected forests, and Verra-verified carbon finance that keeps the clean cooking impact flywheel turning for Signina investors’ living legacy.

Tubeho Neza — “live well”

Capital sequence — read this first

1. USD capital in 2. Later: preference shares

Early Signina-era funding was not preference shares from day one. Public Companies House filings show USD-denominated capital (Preferred share allotments in USD; articles also provide for convertible notes) flowing into DelAgua Water Testing Ltd first. Only later do the filed accounts treat the position as redeemable preference share equity (YE 2016 prior-period restatement of ~£24.69m prefs from debt-like treatment to equity). See the timeline for dated filings.

On the public record The UK vehicle is DelAgua Water Testing Ltd (Companies House 05940720) — later the platform seed behind Tubeho Neza. Signina Capital Funds AGmvK segments appear on the public DWT shareholder list as holders of USD Preferred shares (AR01 2015).

The arc

How belief became distribution

A simple chain — from investor conviction to community health workers at the door — that still delivers every day.

01

Patient capital

Early Signina Capital investors funded the architecture for scale — USD capital into DelAgua Water Testing first, later held as preference shares — patient platform funding, not a one-off charity drop.

02

Platform & partnership

DelAgua built Tubeho Neza with the Government of Rwanda across nearly every district.

03

Free at the point of need

High-quality stoves reach households who would otherwise stay on three-stone fires.

04

Verified climate finance

VCS-certified credits fund education, CHWs, monitoring — and the next wave of stoves.

Impact in numbers

Tubeho Neza, measured

Featured figures from DelAgua’s public impact materials — the scale early capital helped make possible.

To Date

0 stoves distributed to households
0 lives improved

Our Stoves By Numbers

0 reduction in household air pollution when using the stove outdoors
0 reduction in cookstove emission exposure among children
0 reduction in diarrhoea in children under 5 when using boiled water
0 less wood required than a traditional 3-stone fire

On Project Completion

0 of forestry saved annually — an area the size of Manhattan
0 football pitches of forest protected each year
0 tons of CO₂ saved annually
DelAgua impact infographic: stoves distributed, lives improved, health and climate metrics

The same story Verra tells in its Rwanda case study — health, forests, and high-integrity carbon finance working as one system.

Featured “To Date” figures (1.8 million stoves; 7 million lives) per DelAgua public materials / impact infographic. Verra’s case study (July 2026) cites 1.7 million households with a stove and 6.8 million people impacted — earlier programme snapshots that may lag the latest DelAgua totals. Percentage and completion figures also from DelAgua public materials; Verra additionally notes ~3.1 MtCO₂e reduced annually under current verification framing. Sources: delagua.org, Verra case study.

Verified impact

How Verra frames Tubeho Neza

Independently told on Verra’s case-study desk: free clean cookstoves, community health workers, and VCS-certified carbon finance that funds the programme at scale.

Live well, free of charge

Tubeho Neza (“live well” in Kinyarwanda) delivers high-performance cookstoves to rural households who cannot afford the upfront cost — replacing three-stone fires that drive smoke exposure and long firewood walks.

Health, time, and forests

Verra highlights ~71% less firewood, sharply lower household air pollution, and lighter fuel collection for women and children — with education and follow-up through thousands of community health workers.

Integrity through VCS

Projects registered under Verra’s Verified Carbon Standard (including Projects 3699 and 4150) use methodology VM0050 so emission reductions track real, household-level stove use — the credits that keep free distribution possible.

Immediate, multi-benefit impact

As Verra’s energy lead puts it: few interventions change lives as immediately as a clean cookstove — climate finance delivering health and opportunity while cutting emissions at scale.

What capital made possible

Homes, health workers, cleaner air

Tubeho Neza pairs every stove with education and support through community health workers — so the technology is used, trusted, and lasting.

Community health workers instructing a family on stove use

Education at the door

CHWs visit families to teach safe use — Verra notes 8,000+ local jobs for community health workers supporting the programme.

DelAgua cookstove in daily use

Less smoke, less wood

Up to 73% less household air pollution outdoors; 71% less wood than open fires.

Families carrying new cookstoves home after distribution

Free at the point of need

Stoves reach rural households who could not otherwise choose a stove over school fees or care.

Climate & forests

Carbon finance that keeps kitchens clean

High-integrity carbon credits fund free distribution — a model that turns climate finance into daily dignity.

On project completion, DelAgua materials describe saving 64 km² of forestry annually and 4.08 million tons of CO₂ each year — while families cook with far less firewood.

That flywheel — capital → stoves → verified credits → more stoves — is the lasting architecture early investors helped make possible.

Improved cookstove using far less wood than traditional methods

For the Signina community

Your capital has a living legacy

“Tubeho Neza” — live well.

To every early Signina Capital investor: thank you. The kitchens lit, the hours of firewood saved, and the cleaner air in rural Rwanda are part of what your belief helped unlock.

What is delagua-signina.capital?

A historical investor-impact celebration for early Signina Capital investors and DelAgua’s Tubeho Neza clean cooking programme in Rwanda — public KPIs, Verra framing, and the living legacy of patient capital.

What is Tubeho Neza?

Tubeho Neza (“live well”) is DelAgua’s Rwanda clean cookstove programme, delivering free high-performance stoves to rural households and linked to Verra-verified climate outcomes.

How are Signina Capital investors connected to DelAgua?

Early Signina Capital investors backed the platform thesis behind DelAgua Water Testing Ltd (UK Companies House 05940720), helping seed the architecture that later scaled Tubeho Neza across rural Rwanda.

Where can I verify the impact figures?

Start with DelAgua’s Project Rwanda and Verra’s Tubeho Neza case study, plus the film in the section above.

What does the funding timeline cover?

A detailed public chronology (52 milestones): Companies House capital filings show USD-denominated Preferred share allotments into DelAgua Water Testing first; YE 2016 accounts later restate redeemable preference shares as equity. Then Tubeho Neza scale-up, Verra Projects 3699 & 4150, Article 6 labels, VM0050, and today’s measured impact. Scroll #timeline; capital cards are highlighted.

Was Signina capital preference shares from day one?

No. Public Companies House filings show large USD Preferred allotments (e.g. 30 Sep 2014: 21,999,650 × US$1) and articles that also provide for convertible notes. Only later do the YE 2016 accounts restate ~£24.69m redeemable preference shares as equity rather than debt. See #capital-sequence and the highlighted timeline cards.
