For businesses that depend on petrol and diesel to power vehicles, generators and daily operations, knowing how much fuel is purchased is only part of the challenge.
The bigger question is whether the fuel is being used as intended.
This is the problem Tango Brook Technologies Limited is trying to address with technology, data and real-time monitoring, as the Nigerian energy technology company expands its operations across five African markets.
One year after launching its Tango Fuel App in September 2025, the company says it has evolved from a fuel management solution into an energy technology and intelligence platform serving businesses in Nigeria, Ghana, Sierra Leone, the Democratic Republic of Congo (DRC) and Zimbabwe.
The company now has more than 150 corporate customers, including Flour Mills of Nigeria, Seven-Up Bottling Company, LAGRIDE, United Bank for Africa, CardinalStone and ICS Outsourcing.
At the centre of its strategy is the use of data to give businesses greater visibility over energy expenditure.
The Tango Fuel App combines payment cards with fuel tracking technology to enable organisations to control and trace fuel transactions.
According to Tango Brook, the objective is to help businesses understand not just how much they spend on fuel, but where the money is going and how consumption relates to actual operations.
The company recorded significant growth between January and August 2026.
Wallet funding increased 12.4 times, while revenue grew by 46.7 per cent. App transactions and active transacting cards both increased 3.4 times.
The growth comes as businesses continue to look for ways to improve operational efficiency and control costs associated with fuel consumption.
Chairman of Tango Brook Technologies Limited, Peter Atuma, said the company was established to address what he described as a persistent accountability problem in energy spending.
“Across emerging economies, organisations spend billions on petrol and diesel to power vehicles, generators and operations, yet rely on manual processes that create fraud, leakages and zero visibility,” Atuma said.
He said Tango Brook’s first year had demonstrated the demand for technology capable of providing greater control over energy expenditure.
“From an idea to a solution, from a solution to more than 150 corporate customers, from Nigeria to Africa and beyond — the Tango journey has begun,” he added.
Tango Brook has expanded its platform beyond fuel payments with the introduction of two additional products: Tango Fleet Management and Tango GenVault.
Tango Fleet Management uses telematics and fleet intelligence to provide vehicle tracking, route optimisation and operational visibility.
Tango GenVault focuses on generators, monitoring runtime, diesel consumption, refuelling events and unusual consumption patterns.
Together with the Tango Fuel App, the products create an integrated system covering fuel transactions, vehicles, generators and energy consumption.
The company said this allows finance and operations teams to bring different areas of energy spending into one technology ecosystem.
Rather than relying solely on manual records, businesses can use transaction and operational data to identify consumption patterns and investigate unusual activity.
This represents a broader shift in Tango Brook’s business model, from fuel and fleet management to energy technology and intelligence.
Tango Brook’s expansion is also being supported by its ISO 27001:2022 certification, an international standard focused on information security management.
Managing Director, Africa, Obiajulu Wemambu, said the certification was part of the infrastructure required to build trust and support the company’s expansion into new markets.
“One of the most significant milestones in our journey has been the development of the infrastructure, partnerships, and governance required to scale beyond our original market,” Wemambu said.
He said the company was positioning itself for a pan-African future, with expansion into Ghana, Sierra Leone, the Democratic Republic of Congo, Zimbabwe and other prospective African markets.
The company’s Chief Executive Officer, Tango Brook Technologies Nigeria, David Ita, who assumed leadership in January 2026, said the business had to rebuild its technology architecture and strengthen partnerships as it scaled.
“We had to rebuild our technology architecture, strengthen critical partnerships, and navigate resource constraints. The market has validated that work,” Ita said.
According to Ita, Tango Brook has established entities in five African markets as it builds towards an African and ultimately global footprint.
As the Tango Fuel App enters its second year, the company said its focus will increasingly shift towards deeper data intelligence and predictive analytics.
It also plans to expand its local teams and partnerships in new markets and introduce features aimed at SMEs and individuals seeking greater control over energy costs.
The broader objective is to use data to move energy management from a largely reactive process to one where businesses can identify patterns, monitor consumption and make more informed operational decisions.
For Tango Brook, the opportunity extends beyond tracking fuel purchases.
It is about using data to answer a fundamental business question: Are companies getting the value they pay for every litre of fuel they consume?
