On March 11th I leave One Acre Fund and fly from Nairobi to Frankfurt, on my way back to the USA.

It feels a little like leaving Microsoft in 1982 might have if you had an inkling of the future trajectory of the company. The core model in Kenya is much more mature than it was eighteen months ago: we now have three districts with 3,000 to 4,000 clients each, all generating performance numbers that in aggregate are steady and predictable. We have very promising trials underway to achieve better economies of scale and more impact for our clients. When I first got here it felt like building a car - suspension, frame, engine, speedometer and steering wheel - while the car was already on the road. Now it feels like we have the platform and we're tuning for performance. We have incredibly ambitious growth targets (seriously. ambitious.) and I believe we'll reach them.

So it's obvious I have mixed feelings about this. But when I brought up the subject of leaving with our executive director in October, I mentioned that I've been overseas for two years, and working in operations management for, now, eighteen months. I've got a better idea of what I want in life, and it involves building a life closer to family and friends, and going back to a career with a heavier analytical component. One Acre Fund's strength is a laser focus on field results, which means living here and staying devoted to implementation. There are a lot of people that are happiest doing exactly that (did I mention how rewarding it is to see a good harvest?) so I'm not worried about One Acre.

It's not the end of my work on behalf of One Acre Fund, either. I'll be fundraising, blogging about their progress and in general not shutting up about it whenever the conversation turns to development. I'll also be doing some volunteer country scouting if the timing works out.

The next set of opportunities is looking exciting too, though. More later.
