The Promise That Became a Movement: Navjot Sawhney and the Washing Machine Project

Most startups begin with a market gap. This one began with a promise. When aerospace engineer Navjot Sawhney told his neighbor in South India that he would one day build her a washing machine, he had no product, no funding, and no roadmap. What he did have was 20 hours a week, the time Divya was losing every single week just to hand wash her family’s clothes. That promise is now the Washing Machine Project: a social enterprise operating in 15 countries, with 100,000 lives positively impacted and a Time Magazine Best Invention to its name.

From Dyson to dust roads

Sawhney’s path was not a straight line. Born into a South Asian family where university was non-negotiable, he studied aerospace engineering, joined Dyson’s graduate program, and spent three and a half years designing products for, as he put it, “a rich person’s vacuum cleaner.” The mismatch was obvious. He left to volunteer with Engineers Without Borders in South India, designing fuel-efficient cookstoves for communities that still relied on wood fires. It was there that he met Divya and everything changed.

His first instinct was simple: buy her a washing machine. Her response was simpler still. She had no generator, no running water. His off-the-shelf solution meant nothing. So he made the promise instead: one day, he’d build her one that worked.

The world’s first flat-pack washing machine

What followed was not an overnight invention. Sawhney enrolled in a master’s program in humanitarianism, began pitching the idea to colleagues at the UN and Oxfam, and eventually prototyped the first version with a friend over a single weekend, sourcing parts from Amazon. The two flew to Iraq to test it. It leaked. The clothes barely cleaned. And yet, the people who tried it said: this could work.

That prototype has since evolved through four or five generations, shaped almost entirely by user research. The team has conducted over 3,000 interviews with families across 15 countries, mapping water access, detergent habits, clothing types, washing time, and what people would do with the hours they got back. The result: a direct-drive, flat-pack washing machine with no gears, engineered for low-resource environments. No generator required.

Built for where the need is

The Washing Machine Project does not chase the easiest deployments. Its machines have gone to orphanages in Kenya, hospitals in the Republic of Congo, refugee camps in Uganda, and hospitals in Gaza. The mission statement is unambiguous: washing clothes should leave no one behind.

“We’ve been so sensitive to where the need is and the need is global. So if someone wants to request a machine, we honor it.”

To date, approximately 1,000 machines have been built and distributed. The next order will add another 1,000, with 3,000 more planned for the following year. The target is bulk orders from NGOs, UN bodies, and governments, shipped out of India at scale. A 40-foot container holds 150 machines. Sawhney’s ask to potential partners is straightforward: if you can impact people through volume, let’s talk.

Profit with purpose

Sawhney is deliberate about the enterprise model. The Washing Machine Project is registered as a Community Interest Company, a social enterprise, with a separate charitable foundation alongside it. He has no interest in personal wealth from the project, but he is adamant about one thing: sustainability cannot be an afterthought.

• End users receive machines free of charge
• Revenue comes through NGO, government, and foundation partnerships
• Whirlpool Foundation has been a key corporate partner for three to four years
• The organization started volunteer-run; paid talent now drives scale

The logic is pragmatic. US foreign aid cuts and UK aid reductions have shown exactly what happens to organizations built entirely on grants. Sawhney is building to outlast the funding cycle.

Resilience as a design principle

Asked what keeps him going through the hard stretches, Sawhney’s answer was quiet and direct: fall in love with the problem, not the solution. Solutions change. The problem does not. And for him, the problem is still staring back. Fifty percent of the world hand-washes clothes, a burden that falls disproportionately on women and girls, and nobody else is tackling it at this scale.

“You need something deeper than awards, money, respect. It has to go somewhere deeper than external validation.”

He is not looking for an exit. He describes the Washing Machine Project as his last job, for as long as possible.
