ColdHubs was founded in 2015 in Owerri, in Imo State, Nigeria. The main objective was to provide an option for farmers and merchants who lost income as a result of the spoilage of fresh produce due to a lack of cold storage facilities.

Each 3m2 cooling unit can hold three tonnes of food, with customers renting 20kg capacity crates to store their products at the hubs that are available all day, every day.

In 2017, two years after starting operations, the company ran 25 cold hubs in three states of Nigeria with a team of just seven. Today, it has 54 hubs in 22 states, with a total staff of 68. 

The startup will have an additional 18 hubs switched on before the end of the year, with staff likely increasing to 85.

In 2021, the company reported it had been able to store 50,700 tonnes of food that could, otherwise, have gone to waste. For this year, it hopes to reach 150,000 tonnes.

Over the years, ColdHubs has benefited from various grants to execute its expansion plans, including funds from USAID, the Swiss RE Foundation, and the Government of Japan. 

As part of funding received from GIZ, the German agency for international cooperation, it is now looking to expand to neighboring Benin.

In the future, ColdHubs wants to position itself for commercial equity and debt funding. To attract this funding, it is diversifying operations. 

ColdHubs has also increased its production of returnable plastic crates used for the packaging of fresh produce.

Furthermore, to increase the possible client base, the company successfully developed solar-powered phase-change cooling technology suited for the fish and meat value chains.

 Phase-change materials are cooled when there is sufficient sunshine to power the unit and then, owing to their material properties, keep a steady cool temperature during nightfall or overcast conditions.

How it Works

Extending Shelf-life of Perishable Food

Their innovation, ColdHubs, is a “plug and play” modular, solar-powered walk-in cold room, for 24/7 off-grid storage and preservation of perishable foods.

It adequately addresses the problem of post-harvest losses in fruits, vegetables, and other perishable food.

ColdHubs are installed in major food production and consumption centers (in markets and farms), farmers place their produce in clean plastic crates, these plastic crates are stacked inside the cold room. 

This extends the freshness of fruits, vegetables, and other perishable food from 2 days to about 21 days. 

The solar-powered walk-in cold room is made of 120mm insulating cold room panels to retain cold.

Energy from solar panels mounted on the rooftop of the cold room is stored in high-capacity batteries, these batteries feed an inverter which in turn feeds the refrigerating unit.

For its unique pay-as-you-go storage service, ColdHubs has predominantly used cash transactions. 

A customer would pay 200 Nigerian naira (about half a US dollar) to store fresh produce in a 20kg returnable plastic crate, for one day. If they don’t pick it up the next day, they must pay the additional daily rate for the time it was stored.

As the company serves mostly lower-income small-scale farmers and vendors, it has been difficult to introduce any digital form of payment. 

ColdHubs is working on a unique payment option, which will be launched next year, and hope to see adoption from its existing customer base.

ColdHubs’ existing facilities can run for three days without full sunshine. The maintenance of the units is digitally managed; every unit sends a digital signal to the central operating team who can determine whether it is functioning. 

Routine maintenance is done every three months and a technical team collects data daily on the solar irradiation levels, ambient temperature, and even the number of times the doors are opened. 

Flexible Pay-As-You-Go- Store Model

Coldhubs offers farmers a flexible pay-as-you-store subscription model. In preparation for storage, farmers transfer their perishable foods into our reusable crates, which fit neatly onto the shelves. 

Farmers pay a daily flat fee for each crate of food they store.

Heifer International Selects Founders of ColdHubs and Hello Tractor as Winners of Inaugural AYuTe Africa Challenge.

As winners of the AYuTe Africa Challenge, the companies will receive a sizable monetary investment, a total of US$1.5 million in grants, along with ongoing support from a team of expert advisers—accomplished business veterans—to help them translate their funding into an aggressive expansion strategy. 

This is part of Heifer International’s efforts to support young entrepreneurs in developing affordable tech innovations to scale their businesses. 

Doing so ensures greater access to services that enable African farmers to overcome long-standing challenges while encouraging a new generation to pursue opportunities in agriculture.

While many agritech competitions focus on early-stage companies and ideas, the AYuTe Africa Challenge seeks innovations that are market-tested, farmer-ready, and poised to provide an impact that will cascade across the food systems of multiple countries. Both Hello Tractor and ColdHubs meet those criteria. 

Heifer International conceived the idea for the AYuTe Africa Challenge (AYuTe stands for Agriculture, Youth, and Technology) based on four decades of work as a trusted partner of African farmers—and seeing first-hand the stark difference between local farms that have access to new technologies and those that do not.
