How to Use the Lean Startup Method in Kenya: A Practical Guide

To use the lean startup method in Kenya, write down the assumption your business depends on most, build the smallest thing that tests it, measure what customers do, and then decide whether to keep going or change course. The method comes from Eric Ries' book The Lean Startup. In Kenya, a WhatsApp number and an M-Pesa till are often enough for a first test.

The method was written up in the United States, but the loop at its centre works anywhere people buy things. Below I set out the method as Ries describes it, then show how it can look here. The Kenyan scenarios below are made-up examples, written to show the steps.

What is the lean startup method?

Eric Ries set out the method in The Lean Startup, published by Crown Business in 2011 (Wikipedia). The book's own site lists five principles (The Lean Startup):

1. Entrepreneurs are everywhere. You do not need to work in a garage to run a startup.
2. Entrepreneurship is management. A startup is an institution and needs managing like one.
3. Validated learning. A startup exists to learn how to build a sustainable business, and that learning should be tested with evidence.
4. Innovation accounting. Measure progress, set milestones and decide what to work on next.
5. Build, measure, learn. Turn ideas into products, measure how customers respond, and learn whether to pivot or persevere.

Two more terms come up often. A minimum viable product (MVP) is the smallest version of your idea that lets you start learning. A pivot is a change of direction based on what you learned, keeping what still works.

How does build, measure, learn work?

Run the loop backwards when you plan it. Decide what you need to learn, then what you would measure to learn it, then the least you could build to get that measurement.

• Learn: write the assumption as a sentence you could prove wrong. For example: "Parents in our estate will pay KES 500 a month for school pick-up alerts."
• Measure: choose one number that would settle it, and set the pass mark before you start. For example: at least 15 of 50 parents pay for a second month.
• Build: make the cheapest thing that produces that number. Often that is a manual service run over WhatsApp, with the app built later.

Write the pass mark down before you start, because without one any result can look like good news.

What does build, measure, learn look like in Kenya?

Here are two made-up examples.

Example one: a laundry pick-up service in Ruaka. The founder's assumption is that young professionals in apartment blocks will pay for weekly pick-up. She builds no app. She sets up a WhatsApp Business number, puts flyers up in three blocks, and takes payment through an M-Pesa till. She measures one thing: how many first-time customers book a second pick-up within a month. If fewer than a third return, she tests a different price or a different estate before writing any code.

Example two: a restocking tool for duka owners in Kayole. The founder believes shopkeepers will order stock through him if it saves them a trip to the wholesaler. He starts by taking orders by phone and WhatsApp and buying the stock himself. He measures how many shops order again in each of the next four weeks and how much he earns per order after transport. If shops reorder but he loses money on each delivery, the learning is about his costs, and he changes the delivery model before building an ordering app.

In both examples, money changing hands is the signal. Payment through M-Pesa or a card tells you far more than someone saying they like the idea.

How do I choose what to measure?

Ries calls the practice of measuring progress innovation accounting. In practice, pick numbers that show customer behaviour and that you can act on:

• How many people pay, and how many pay again.
• How much you earn per customer after the cost of serving them.
• How long it takes a new customer to come back.
• Where people drop off, such as between seeing the offer and paying.

Be wary of totals that only ever go up, such as page views, followers or app downloads. They can grow while the business stands still. Compare groups instead: of the people who joined in October, how many were still paying in November?

When should I pivot and when should I persevere?

Set a review date before you start, for example every four to six weeks, and look at the evidence against your pass mark. If you keep missing it after a few honest attempts, change one big thing: the customer, the problem, the price or the channel. Keep what worked. If you are hitting it, keep going and test the next assumption on the list.

Small early bets make pivots cheaper. The less you have built on an untested assumption, the less it costs to change course.

What mistakes do founders make with lean startup?

• Building too much. A full app with log-ins and dashboards is rarely the smallest test.
• Testing only with friends. Friends tend to be kind, so strangers who pay give you better data.
• Counting interest as demand. "Interested" replies on WhatsApp are a starting point. Ask for payment or a deposit.
• Changing the pass mark afterwards. Decide it in writing and stick to it.
• Running tests forever. Each experiment should end with a decision.

Where can I practise the lean startup method with other founders?

Work alongside people running the same loop. The Hackhouse Residency is a 12-week programme that takes no equity and asks for about 20 hours a week, with sessions on Wednesdays from 3 to 9pm and Saturdays from 2 to 4pm. Applications for HH Gen 27.1 are open for the Spark track (idea stage, KES 25,000) and the Scale track (growth stage, KES 35,000). You can also see other programmes on our programmes page.

Key facts

• The lean startup method comes from Eric Ries' book The Lean Startup (Crown Business, 2011).
• Its loop is build, measure, learn, with each cycle ending in a decision to pivot or persevere.
• An MVP is the smallest version of your idea that lets you start learning.
• Set the number you will watch, and its pass mark, before you run the test.
• In Kenya, a WhatsApp number and an M-Pesa till can run many first experiments without code.
• Payment and repeat purchase are stronger evidence than likes, sign-ups or downloads.

Frequently asked questions

Does the lean startup method work outside Silicon Valley?

Yes. Its first principle is that entrepreneurs are everywhere. The loop of testing an assumption with customers works in any market, and Kenya's mobile money makes paid tests easy to run.

What is a good MVP for a Kenyan startup?

Often a manual version of the service: a WhatsApp number, a simple form, an M-Pesa till and a person doing the work by hand. Build software once you know which parts customers pay for.

How long should a lean experiment run?

Long enough to see repeat behaviour, which for many consumer products is a few weeks. Decide the length before you start.

Do I need to read the book?

It helps. The Lean Startup explains the reasoning behind each step, and the principles are summarised on theleanstartup.com.
