Built to last: The Bangladeshi climate start-ups that don’t depend on grants

By Eshrat Waris, Director, Strategic Partnerships & Investments, British Asian Trust 

All over the world, climate projects start with big promises and end quietly when the funding runs out. The technology may work, the need may be real but if there is no solid way to earn money, the impact fades once the grant ends.

In Bangladesh, some climate enterprises are trying to break this pattern by building businesses where climate impact and income go hand in hand. This matters because climate finance is still limited and often short-term. Developed countries had promised to mobilise USD 100 billion a year; by 2021, they had reached around USD 89.6 billion, according to the Organisation for Economic Co-operation and Development (OECD), and much of it was delivered through time-limited projects.

Start-ups such as Deshifarmer, Nodes Digital, and BAU Silage are taking a different route: commercially sustainable solutions that continue operating through flood years, high inflation and political cycles, because customers see value worth paying for. 

That is where the British Asian Trust’s expertise in social finance becomes especially relevant. Social finance structures funding so it rewards results and helps effective ideas grow, often by blending philanthropic funding with investment capital, and using tools like outcomes-based funding, repayable finance and technical assistance to make early-stage ventures investable. Applied to climate, it can move solutions from pilot to scale. 

Deshifarmer: Less waste, more income 

Deshifarmer focuses on what happens after harvest. In many places, fruits and vegetables rot in fields, at collection points and on the road; globally, the Food and Agriculture Organization of the United Nations (FAO) estimates about 14% of food is lost between harvest and retail.Deshifarmer connects farmers to markets through an integrated “seed to market” model: 

  • It supports contract farming, providing farmers with better seeds, advice and a guaranteed buyer. 
  • It uses technology to plan harvesting, transport and sales. 
  • It builds a network of local microentrepreneurs to coordinate everything on the ground. In its targeted areas, food waste has fallen to about 5% and farmer incomes have risen by at least 25%.  Emissions drop because less food is being wasted. 

Revenue comes from input sales, produce sales and service contracts; the climate impact is inseparable from the commercial model. 

This is the kind of venture that social finance is designed to back. With the British Asian Trust’s support, models like Deshifarmer can strengthen their unit economics, sharpen their measurement of outcomes such as reduced loss rates and income gains, and become ready for financing that rewards performance, expanding into new districts without a new donor round every year. 

Nodes Digital Limited: Savings comes from little information 

Nodes Digital tackles a quieter form of waste: water. Its tool is deliberately simple, a length of PVC pipe fitted with a small sensor that measures the water level in a field and sends instant updates, so farmers know when to irrigate and when there is already enough. The model: 

-Cuts pumping costs by helping farmers apply the right amount of water and irrigate less often, while maintaining or improving yields. 

-Keeps digital records that evidence the environmental benefits and may open future carbon credit opportunities. 

-Let's several farmers in a community rent and share one unit, making it far cheaper than individual ownership.

Because the equipment earns its keep through rental and lower running costs, farmers adopt it on commercial grounds rather than as a subsidised trial. At scale, that same record-keeping positions them to benefit from environmental incentive and carbon markets as those mature.

BAU Silage: Simple ideas that last 

BAU Silage, developed out of Bangladesh Agricultural University, looks less high‑tech but matters just as much. It helps farmers preserve fodder as silage, so animals have good feed year round, an approach the FAO has long promoted to protect livestock from seasonal feed shortages. The model: 

  • Supports farmers to grow special fodder crops under guaranteed purchase contracts. 
  • Turns harvest into stored silage for livestock farms. 
  • Uses manure as fertiliser to close the loop. 

Farmers pay because their animals stay healthier and productive, even when floods or droughts hit. Combining technical assistance to strengthen production and distribution with repayable capital to fund working capital and inventory, this model can widen its reach while staying focused on smallholder realities. 

Why these initiatives matter 

Together these examples point to a bigger shift thinking: climate solutions that last tend to rest on a business model, not a donor project plan. That is the logic behind impact investing, where investors look for both financial returns and measurable social or environmental benefits, as described by the International Finance Corporation (IFC). With the British Asian Trust’s innovative finance expertise, structuring funding around outcomes and commercial viability, these ventures can move beyond pilots and scale what works.

Bangladesh is often framed as a climate victim. These enterprises highlight a country where practical, durable climate innovation is being built to survive in the real economy. They are built to stay.
