About the Innovation
Kenya’s horticulture sector faces a number of significant supply chain and marketing challenges that
hurt smallholder farmers and discourage private sector efforts to invest in improvements. These
include poor market linkages, information and power asymmetries, high costs, low traceability from
farm to market, and cash flow challenges.
Agrimanagr is a produce-purchasing innovation that provides transparency and integrity in the supply
chain. The technology accurately tracks production and quality for individual farmers, ensuring that
they are properly paid and rewarded for exactly what they deliver. It provides buyers with complete
visibility into the supply chain, quick electronic reconciliations, and a powerful platform to efficiently
provide extension services, mobile money payments, among others. Agrimanagr represents a major
departure from current practice in most Kenyan agricultural where the typical set-up involves an
inaccurate manual weighing scale and a buying process that provides many opportunities for errors
and fraud.

Mr. John Waibochi is the Founder and CEO of
the Virtual Group of Companies. In 2010, the
company won the Nokia Growth Economy Venture
Challenge - which came with a US$1,000,000 cash
prize - beating competition from 54 other countries
to take the prize and putting him squarely on the
world map as a top tech entrepreneur. The firm
has also received a US$1.5 million convertible
loan from the Acumen Fund for the development
of a mobile-based agricultural application to help
small-scale farmers market their produce. John’s
innovations have also earned him/the firm other
honors such as the World Summit Award Mobile
2010; Moran of the Order of the Burning Spear;
Africa Enterprise Challenge Fund; Legatum Africa
Award for Entrepreneurship; and the Dale Carnegie
Highest Award for Achievement.

become a formidable force in East Africa because
it is not only transforming logistics management for
big companies, but because it is addressing the real
issues by pioneering mobile business management
solutions for smaller traders. Virtual City is a
mobile supply chain and knowledge management
company. According to John, when it comes to
mobile’s next-big-thing, Kenya is the country to
watch because of its early and leading adoption of
m-commerce, large investments in terrestrial and
submarine fiber, the government’s strategy to grow
the Business Process Outsourcing sector and lastly,
the position of Nairobi as the “unofficial” business
capital of the East African community’s common
market. Acquiring high-level technological talent is
what keeps him up at night. While there are enough
entry-level programmers in Kenya for Virtual City
to take its pick, a business as successful as this
creates a hungry demand for top talent. John’s
goal is to consistently develop innovative mobility
solutions that simplify lives.

About the Innovation
It is estimated that 30% to 50% of horticultural commodities are lost between production and
retail sites. This is two to three times the losses that occur in developed countries. The losses
mean lost income, labor, inputs, and natural resources for smallholder farmers. Temperature
control is the single most important factor in the preservation of perishable food; the rate of
deterioration of perishables increases an approximated two to three-fold with every 10°C
increase in temperature in the commodity’s physiological temperature range. While most farmers
may be aware of the benefits of maintaining a cold chain for perishable commodities, most of
them, especially smallholder farmers, lack capital to invest in standard refrigeration equipment and
cold storage rooms. As a result, they are forced to sell perishable commodities as soon as they are
harvested through middlemen or brokers who often exploit them.
Our innovation is a cooling and cool-storage technology, especially useful for perishable
horticultural commodities. The CoolBot is an inexpensive controller for a standard window or
split-unit air conditioner unit that enables these units to cool rooms down to optimal storage
temperatures of 0 to 150C, without ice accumulation on the evaporator coils. In combination with
a well-insulated room constructed from local materials, this locally-available, relatively-inexpensive
cooling system makes cold storage a viable option for smallholder farmers. The technology will
initially target farmers who are organized in producer/commodity groups, market groups or
cooperatives, and can therefore benefit from economies of scale. With these facilities, farmers
can store their produce for prolonged periods thus extending the marketing period.The potential
for bringing cooling power to rural communities is evident, and the intention is to continue this
research through the Innovation Engine project.

Unit at the University of Nairobi’s Department
of Plant Science and Crop Protection. Since
2008, Jane has lectured, carried out research
and outreach at the University, and coordinated
students’ research projects, as well as the Msc
Horticulture Program. Over the years, through a
number of research grants she has won, she has
supported several graduate students’ research
and played the role of mentor. Her outstanding
authorship/co-authorship of six papers in
referred journals and over 20 conference papers
locally and internationally has earned Jane the
prestigious AWARD Fellowship (African Women
in Agricultural Research and Development, 2013
-2014) and the Norman Borlaug Fellowship
(2012-2013). Activities of the two fellowships
have helped her foster collaborative activities and
created linkages with other local and international
institutions.
