Joseph Nguthiru, Kenyan climate-tech engineer and founder, smiling with arms crossed
UN Young Champion of the Earth

I turned the weed choking our lake into a company.

Then tens of millions of people started paying attention.

I'm Joseph. Engineer, founder, and proudly Nairobi-made. A kid from Eastlands who learned to make a lot out of a little, now building climate ventures that turn the continent's hardest problems into its next industries. Fair warning: I talk fast when I'm excited, and these days I'm always excited.

The moment it broke out

A clip of one of my talks caught fire across the internet, and the counter still hasn't stopped. The reach is nice. What it really did was open doors: investors, partners, and a few people I'd grown up watching on TV.

Where it starts

Eastlands taught me to make a lot out of a little. A stuck boat showed me where to aim it.

I'm from Eastlands, Nairobi, the hard-working east side of the city, where ambition usually outruns opportunity and you learn early to build something out of almost nothing. If you're reading this from a place like that, anywhere in the world, take it as proof: the ceiling sits a lot higher than they told you.

I trained as a civil engineer. On a university field trip, our boat sat trapped for five hours in a thick mat of water hyacinth on Lake Naivasha, the same invasive weed that traps the lake's fishing families every single day, clogging their engines and cutting off the catch they live on.

Five hours staring at a weed will make an engineer restless. Everyone around me wanted it gone. I got curious about what it could become. That question became my final-year project, and then it became HyaPak.

Off the record

The founder, minus the press release.

Long before climate-tech ate my calendar, I wanted to be a DJ. I was, let's just say, more gifted at engineering, but I still think a good set and a good pitch are the same job: read the room, build the energy, and know exactly when to drop the thing everyone came for. I'm born-again, I serve on my church's media team, I'll cheerfully argue that wrestling is just theatre for engineers, and I'm a long-suffering Chelsea fan. When I say "let's grab coffee," I mean the coffee too.

They wrote off the weed. I put it on the payroll.

Because Africa's biggest problems aren't liabilities. They're its next industries, wearing a disguise.
