Building a highway to Series A for Africa's leading Climate Tech startups 


A critical time for climate in Africa

Greenhouse gas emissions (GHGs) need to be reduced from 50bn tons currently to zero tons by 2050 to avoid a global climate disaster.


While Africa is currently contributing around 3% of global GHGs, this will drastically change in the future with Africa’s population expected to double in size by 2050.  It is imperative that Africa forges a low carbon growth trajectory for the future of our planet.  We are determined to grow the companies that will get us there.

We offer the financial and human capital to ensure incredible Pan-African climate tech reaches scale and creates impact.

Our 12-month business builder program offers the following:

  • $50,000 through a SAFE agreement with a valuation cap:

    • $25,000  of cash up front

    • $25,000 of co-building and other services

  • 12-month bespoke program consisting of 8 months of active business building and 4 months of support services

  • Dedicated business building team working with cohort companies

  • World-class experts allocated to each team to complete project deliverables   

  • Curated board of directors to provide strategic and governance support

  • Package of additional benefits  (see FAQ’s for more information) 

We're focused on tangible outcomes

Startups don't need talk; they need proactive action to be successful.

Climate Lab executes on defined deliverables to drive growth.


We develop a report with key strategic insights and opportunities to share with stakeholders, investors and ambassadors.


The report serves as the foundation for business building support. 


Startups are in a race against time between product-market-fit and runway. A clear, usable, actionable financial model is not only a must for raising investment but also provides the leadership team with a clear path to success. 

Every team receives a world class model based on their unique operations and objectives. 

Professional Pitch Deck & Training 

A pitch deck is the ideal format to clearly articulate the key aspects of the customer problem, business model, team and milestones.


Every startup will be pitch perfect through training and employing data driven story telling.   

Expert-Led Deliverables

We utilise our robust network of seasoned, experienced experts to help our teams make creative mistakes.

Our Experts work directly with teams in 4-6 week sprints with a clear deliverable as determined through the Diagnostic Report.

Food & AgriTech

The world is a farmer. We support cutting edge technology to make that farmer- and the logistics and processing that gets food on people's plates- more environmentally efficient. This leads to better personal and climate outcomes.

Clean Energy 

Most Africans live off grid. They need to come online. The only way this can occur without massive negative environmental effects is for the lights to turn with clean renewables from day 1. We make that happen.


African cities are growing at an alarming rate. They need solutions that optimize energy efficiency and air quality. We leverage the research and technical ability of Stellenbosch University to design these startup solutions.


The cleanest energy is the energy we don't consume.

 We love technologies that do the same amount of work (or more) but using less energy.
