A year after President Mwai Kibaki came into power, he ordered a probe through a British company identified as Kroll and Associates, which established some of Mzee Moi's hidden properties.
One of the biggest investments unearthed was in the name of Siginon Group, where the report established that ownership was at 12.5% for Joshua Kulei (Moi's long-term PA), 12.5% for Gideon Moi, and 75% for Kabarak University, where Gideon is currently the Chancellor.
Siginon Group is an integrated end-to-end logistics and air cargo solutions provider based in Kenya, Tanzania, and Uganda and has been in existence since 1985.
According to Forbes magazine in 2017, Siginon Group is a 100% Kenyan entity that began as a small clearing and forwarding company before growing into a regional leader in logistics with $100 million(Ksh10 billion) in annual revenues.
The company has specialised in supply chain management with interests in supply chain logistics, ground handling, container freight stations, clearing and forwarding, trucking, warehousing, distribution, and project cargo logistics.
The current Siginon Managing Director Meshack Kipturgo told Forbes that at the time Siginon started, there were no locally-owned freight companies and thus it took advantage of the gap to forge itself into an industry leader.
He revealed that the Group started out as a small clearing and forwarding company in Mombasa and grew bit by bit into being the largest indigenous 'Source to Doorstep' logistics company in East and Central Africa.
"As we cleared cargo, we started getting a lot of requests from our customers who wanted their cargo transported from point A to B. So we bought some trucks to move the cargo to the final destination.
"Then from there, we had the customer asking us whether we could hold the cargo for them for some time because they didn’t need the goods urgently; so we started investing in warehouses.
"We also went into ground handling because we were putting a lot of cargo into aircraft and airlines require terminal handling services such as ground handling, ramp handling, and air cargo handling," Kipturgo stated.
He further stated that Siginon Global Logistics currently provides transportation by sea, air, road, and rail within 12 countries in East and Central Africa through the port of Mombasa and the Jomo Kenyatta International Airport (JKIA).
Kipturgo further stated that the company also banks on Siginon Aviation, a provider of ground and air cargo services located at the Jomo Kenyatta International airport (JKIA) and also Moi International Airport in Eldoret.
"We have invested more than Ksh1 billion in a state-of-the-art air cargo terminal in Nairobi which includes a 5,000 square-metre general cargo warehouse, a 3,000 square-meter perishables centre, a 2,000 square-metre basement parking for transit vehicles and a specialized storage area for dangerous, valuable and temperature-sensitive cargo," Kipkturgo informed in 2017.
The company also runs Siginon Container Freight Station (CFS) located in Miritini, adjacent to the Mombasa Port which caters for importers and exporters moving local cargo or transit containerised cargo as well as vehicular cargo at the Port of Mombasa.
