TLDR
- South African electrotech startup Plentify has raised an undisclosed Series A round to expand into the U.K., Australia, and Brazil
- The round, which brings Plentify’s total funding to nearly $15 million, includes backing from Secha Capital, Buffet Investments, E3 Capital, Fireball Capital, Endeavor
- Plentify plans to scale a model built in South Africa’s unstable power market to regions experiencing similar pressure on ageing grids
South African electrotech startup Plentify has raised an undisclosed Series A round to expand into the U.K., Australia, and Brazil, markets facing growing renewable-energy constraints such as grid congestion and intermittency.
The round, which brings Plentify’s total funding to nearly $15 million, includes backing from Secha Capital, Buffet Investments, E3 Capital, Fireball Capital, Endeavor SA’s Harvest Fund, Satgan, and several family offices.
Founded in 2017, Plentify builds hardware and software that make household appliances operate more efficiently by shifting energy use to periods when power is cleaner and cheaper. It connects devices such as water heaters, batteries, and solar inverters through an AI-based system that coordinates demand. Deployments have grown more than tenfold since 2023, with the company citing South Africa’s load-shedding crisis as the environment that forced rapid innovation.
Plentify now remotely manages nearly 100 MWh of combined water-heater and battery capacity through partners including Balwin Properties, Conlog, and Wetility. The startup says its system has saved 9.9 GWh of electricity and helped households avoid more than R40 million in energy costs.
With smart-energy adoption rising, Plentify plans to scale a model built in South Africa’s unstable power market to regions experiencing similar pressure on ageing grids.

Key Takeaways
Plentify’s raise underscores how South Africa’s energy instability has become a proving ground for smart-energy technologies, now attracting global interest. Rather than focusing on more hardware, Plentify targets the demand side, using software to orchestrate when and how household devices consume power. This approach—similar to early virtual-power-plant models—offers a cost-efficient way to stabilise grids, manage rooftop-solar output and reduce household energy bills. The broader competitive landscape in South Africa reflects a maturing smart-energy ecosystem, with players such as Vesofy, Switch Energy, Evolve Battery, Smappee and CBI-electric offering complementary monitoring, storage and load-management tools. International firms like Sun King, M-KOPA and Zola Electric continue to dominate off-grid markets. But Plentify’s strength lies in tackling grid-connected households that face volatility rather than full energy scarcity. As countries in Europe and Latin America confront rising grid stress from electrification and renewables, Plentify is betting that its South Africa-tested solution can scale. If successful, it could show how software-led demand management becomes a key pillar of global energy-transition strategies.
