Keeping SAโs Heads Above Water
SAโs drowning in the impacts of a serious water crisis, with almost half of the 4.3 trillion litres of municipal water supply never even reaching your taps โ but this companyโs got a planโฆ
South Africa ranked 144th in rainfall with an average precipitation of 495mm. Barely a sixth of 1st-placed Columbiaโs 3โ240mm, but way better than 182nd Egyptโs mere 18mmโฆ
Problem is nearly 98% of SAโs available water resources are already allocated, while per capita water use is around 237 litres per person per day, well above global averages of 173 litres.ย
Why? Well, due to leaks and other issues, SA loses an avoidable 40.8% of its water (1.8 trillion litres, almost a third of the Gariep Dam every year), so water conservation and demand management are the name of the game.

Billions of Rands of drinking-quality water gone (after itโs already been purified and moved).
The local player clawing back SAโs water
Re-Solve is a turnkey water engineering company with two decades of experience in reducing water losses and helping public and private sectors use water more efficiently.ย
Using innovative interventions and data-driven performance models, Re-Solve has saved more than 60 million kilolitres (about 24k Olympic-sized swimming pools) of water nationally, equating to over R1 billion in verified financial savings for its clients.
What makes Re-Solveโs approach really interesting is its performance-based contracting model, where Re-Solve fully funds projects and recoups only on verified savings. So their clients (we're talking government, municipalities and big private sector players) pay them from their water savings. No upfront capital outlay or budget constraints.
Smart backing
By focusing on verified outcomes and real-time monitoring, Re-Solve ensures that every litre saved translates into tangible cost reductions and improved system performance.ย ย
And their model completely de-risks investment: If they canโt cut your consumption, they donโt get paid. Talk about betting on yourself. And in a country leaking almost half of its treated water, thatโs accountability engineered into the contract.

FROM OUR FRIENDS AT SIDEKICK LAB
If you canโt find it, you canโt use it
Many organisations rush into analytics, AI or automation without first identifying and cataloguing their data. Without knowing what exists or where it lives, every strategy relies on assumptions instead of facts.
Up to 68% of business data is unused or unknown, hidden across databases and departments. This โdata paralysisโ slows decisions, blocks progress and weakens trust in insights.
Sidekick Lab helps teams see what they already own.
Our AI agents scan your environment, catalogue your data and build a real-time, searchable map, securely inside your infrastructure.
In days, Sidekick turns data chaos into clarity:
โ
A super-index with business context and guardrails
โ
Natural language queries for real-time answers
โ
Reliable, actionable insight you can trust
Because until your data is known, your roadmap isnโt real.
See what your data is hiding.
IN SHORT

๐ฐ Locstatโs โฌ2.5M Boost. SA AI startup Locstat has secured โฌ2.5 million to take its graph-based AI solutions from Africa to Europe and beyond in a funding round spearheaded by Portugal Gateway Fund (PGF) and joined by ANZA Capital. Nice one.
๐ An e-bike for your feet? Nike has unveiled Project Amplify, basically โa second set of calf musclesโ for peeps wanting to run more while expending less effort. Soon, we won't have to do anything for ourselves.
๐ Goodbye Grey List. South Africa is off the global dirty-money grey list, with the Financial Action Task Force officially removing SA together with Nigeria, Mozambique and Burkina Faso on Friday. Noice.
๐ค Maximus Struts into SA. Maximus, a 35kg, 1.27m tall humanoid robot, made its SA debut at the Singularity Summit last week. Interesting.

BUILDING A BUSINESS IN SA
5 things we learnt in The Founder Collab
You can scale outbound on autopilot. Automation + AI can book calls while you sleep and grow B2B faster than headcount.
โShip earlyโ applies to websites, too. Most users donโt care how itโs built if it solves their problem today.
Collab reach is real. One memberโs survey got instant responses and real user insight within minutes.
SAโs informal economy keeps evolving. New ideas and books like GG Alcockโs Kasinomics Unleashed fuel where the next markets emerge.
Banks arenโt sleeping. AI and agents are already fixing issues live and some players plan to eat the rest for lunch.
Find your founder community. Join The Founder Collab, itโs where 100+ real SA founders help each other to build better, faster every day.
