M-Pesa agent 0001 turned multimillionaire

The morning M-Pesa officially launched on March 6, 2007, Esther Muchemi was already at her shop on Koinange Street. She had tested the system for six months. She knew the product better than almost anyone. What she did not know was that she was standing at the beginning of something that would eventually serve 40 million people and make her one of the wealthiest women in Kenya.

Samchi Telecommunications Limited was the first M-Pesa dealer when the mobile money platform was introduced in the country, and it holds till number 0001. Muchemi was the woman behind that number. “I was the first dealer to roll it out in all my shops. I didn’t know where this thing was going. I didn’t understand it. But I told my people: We’re going,” she said in a later interview with Business Daily.

Nineteen years on, M-Pesa has reached 40 million monthly active users in Kenya, handling transactions worth approximately 38.3 trillion shillings in the financial year ending March 2025, a value that significantly exceeds Kenya’s annual GDP. The woman who processed the platform’s very first transaction built a conglomerate off the back of it.

From Othaya to Nairobi

Muchemi grew up in Othaya constituency, Nyeri County, the firstborn in a family of nine. Her father, Moses Macharia, was a teacher who pushed hard for his children’s education. Primary school was a struggle. She was not a strong student, but her father kept advocating until she secured a place at Kamahuha Girls Secondary School.

High school changed everything. She buckled down, scored an A in her final Kenya Certificate of Secondary Education examinations, and that result took her to the University of Nairobi, where she completed a Bachelor of Commerce degree. She went on to qualify as a Certified Public Accountant with the Institute of Certified Public Accountants of Kenya.

After graduating, Muchemi worked as an auditor at Bellhouse Mwangi, now Ernst and Young, between 1984 and 1988, and later rose to salaried partner at PKF Kenya, where she stayed from 1989 to 1996. She was, by every professional measure, successful. Comfortable. Respected. She left anyway.

The KSh 800,000 bet

In 2000, Muchemi sunk her savings at the time, KSh 800,000, into setting up a shop at Nginyo Towers on Koinange Street that sold phones and mobile hardware. Her husband, Gerald Muchemi, was a military man and communications engineer who would later rise to head the Directorate of Military Intelligence. He had encouraged her to go into the mobile telecommunications business. The two shared a hunch that mobile telephony was about to be the next big thing in Kenya.

It was, by the standards of the time, a leap. Safaricom’s subscriber base stood at fewer than 500,000 users. She had walked away from a senior position at a top-tier audit firm to sell SIM cards and scratch vouchers in downtown Nairobi. People in her circle thought she would not last two years.

The early cash position was tighter than it looked. Samchi had only KSh 50,000 in working capital yet needed to buy stock and pay suppliers. The routine was to buy stock, sell it the same day, collect the cash, bank it, and write cheques for suppliers the next morning. “I remember one bank manager who used to call me every morning and tell me: ‘Esther, your cheque is here, and there is no money in the account,’ and I would tell her: ‘Wait. Wait. Wait. By 10 o’clock, there’ll be money in the account,'” Muchemi recalled.

The Safaricom pivot

The business originally sold products for two operators. Then, in 2001, a senior Safaricom employee walked past the Nginyo Towers shop and called Muchemi. His question was simple: would she consider becoming an exclusive Safaricom dealer and dropping the competition? Esther turned to one of her managers, phone still in hand, and said: “Mr. Ngari, Safaricom is asking whether we would consider becoming exclusive for Safaricom.” Ngari said it would be a good idea. She told the Safaricom representative the same.

It was the right call at the right time. She recruited more than 60 salespeople to push distribution beyond the walls of her single shop. “We didn’t have much to start with. We didn’t even have a big budget for marketing,” she said. “But I believed in the product, and I knew that if we worked hard enough, we could build a customer base.”

Her strategy was two-pronged: deploy agents to sell airtime outside Nairobi first, then set up shop wherever Safaricom went. The company expanded along Kenya’s highways, starting with Nakuru and Mombasa, with the populous Mount Kenya region as a second priority. “That’s why you’ll find that in most of the towns in Mount Kenya, I have a shop,” she said later. “It’s not because I come from there. It is because it was the second strongest market when we opened.”

Agent 0001

M-Pesa was piloted at Samchi for six months before the official rollout. When the service went live, the skepticism was real. Customers wanted to know how money could sit inside a phone. Whether it was safe. Whether it would actually arrive. Many early transactions failed because of network gaps, and even Safaricom was not certain the product would take off. Muchemi and her team spent hours answering questions, troubleshooting glitches and reassuring users. Some days, she barely made any transactions at all.

She stayed the course. In 2009, Safaricom honored her as the top M-Pesa agent in the country. The platform had by then crossed a threshold from novelty to essential infrastructure, and Samchi was embedded at its center.

Widowhood and grief

The same month M-Pesa launched, Muchemi’s personal world collapsed. In March 2007, she lost her husband, Gen. Gerald Muchemi, then Kenya’s chief of military intelligence, after a short illness in the United Kingdom. “When he died, of course the first thing you get is shock, because I was a much protected person. I was delicate physically as a small girl, and even from people’s perspective I was vulnerable. People never thought I would make it. They gave me just two years to live,” she later said.

She had spoken often about what his support meant to her during the years they built together. “When my husband was alive, he allowed me to be. He took pride in my success; he never oppressed it. He was comfortable in who he was as a military person, so my success was never a threat to him,” she said.

She also disclosed that it was her husband who first pointed her toward telecommunications retail, saying it was part of his plan to protect her when he was gone. “My husband, an electrical engineer in charge of communication in the army, was too exposed. He read between the lines and he knew my passion for retail business,” she said.

She carried the business forward without him. “When you lose your spouse, you are not the one who has died. You must chart a way for your life. I decided that my greatness is not over, and I decided to get where I wanted to get,” she said.

The empire

Muchemi organizes her businesses under the Samchi Group of Companies. The group includes Samchi Telecommunications, Jumbo Communications, Forward Airtime and Mergut in the telecommunications sector, alongside Samchi Credit, a microfinance company; Samchi Heights, a real estate development company; After 40 Hotel on Biashara Street in Nairobi; El-Roi Plaza, a shopping arcade on Tom Mboya Street; Heavenly Wings restaurant within El-Roi Plaza; and Space International, a virtual office company. Samchi Telecom alone has more than 50 shops across the country. The group employs over 600 people.

The name Samchi is personal. It is a combination of the first three letters of the names of her two children, Sam and Ciru. The word denotes succession, which is deliberate. Both children now work in the business alongside her.

In 2019, the group also moved into event management, acquiring two companies in that space just before the COVID-19 pandemic hit. The disruption tested the business, but its foundations held.

Muchemi earned a Doctorate in Entrepreneurship from Zetech University between 2017 and 2019. In the same year she received the Global Inspirational Women Leadership Award and was inducted into Amazon’s 100 Global Women Leaders Hall of Fame. She chairs the Safaricom Dealers Association and has authored a book, “Give Me My Mountain,” dedicated to her two children. One of her mentees is Chris Gathingu, the innovator behind Lipa na M-Pesa and the M-Pesa 1Tap solution.

She has consistently declined to quantify her net worth, saying she does not count money and that wealth without impact on society is worthless. What is not in dispute is that the woman who walked into a shop on Koinange Street in 2000 with KSh 800,000, staked everything on a mobile product almost nobody believed in, and processed the very first M-Pesa transaction, built something that will outlast her. Her children are already in the building, learning how she did it.
