(ITA - 2017 - 1 FASE) INSIDE THE BILL GATES-BACKED ACCELERATOR THATS TRAINING THE NEXT GENERATION OF VENTURE CAPITALISTS Lauren Gensler, FORBES STAFF In an airy converted furniture store in Seattles Pioneer Square neighborhood, five novice impactfund managers from Zimbabwe, Guatemala and the Netherlands are rehearsing the sales pitches theyll make the next day to 60 mostly institutional investors, representing $10 billion in capital. The presentations will be a graduation ceremony of sorts. Despite their impressive resumes, the five men have just completed a four-week boot camp covering everything from term sheets, accounting and mezzanine debt structures to dealing with corruption to defining and marketing their brands. Theyll head home with golden contacts (investor cocktail hours were built into the packed schedule) and a commitment for up to $500,000 in seed capital from Capria Accelerator, a first-of-its-kind venture whose initial investors include Microsoft cofounder (and worlds richest man) Bill Gates. One of those rehearsing is Patrick Makanza, 51, an M.B.A. and veteran of Unilever and BarclaysBank, who1quit a cushy job at a top Zimbabwe private equity firm and launched Vakayi Capital. The first fund being formed by Vakayi (which means to build) will back for-profit businesses providing essential services in Zimbabwe, which has per capita gross domestic product of about $1,000. That fund will make loans (with an option to convert some to equity) for an average of four years to small and medium-size businesses that2want to expand and cant get adequate bank financing. Among potential investments: an eye clinic thats building a new operating room so it can double its daily procedures and bring down the cost of cataract surgery; an education microlender; and a builder of low-cost housing. The next day, in their presentation, Makanza and his Vakayi cofounder tackle head-on the tough issues they might be asked about, including Zimbabwes endemic corruption, economic challenges and currency dramasit squelched hyperinflation in 2009 by switching to foreign currencies, primarily the U.S. dollar. But in the question period Tracy Washington, principal investment officer for the International Finance Corp.s global private equity funds, lobs a personal query at Makanza, a father of four who3is partial to conservative business suits and golf. With your resume, she asks, why get involved with so risky an enterprise, and will you stick to it?Makanza responds that4he worked in venture capital back in the 1990s and came to miss the highs and lows of investing in early-stage entrepreneurs. I still have at least ten years to do this. Its a real roller-coaster lifestyle. But I enjoyed it, and I want to have more of that experience again. Impact investing which5aims to produce both financial and social or environmental returns is in vogue. Big names in finance, from BlackRock to Goldman Sachs to Bank of America Merrill Lynch, have beenpiling in recently, seeing it as a way to appeal to the socially conscious Millennials now building and inheritingwealth. But this alternative asset class is still small $77 billion invested worldwide, according to a new survey from the Global Impact Investing Network. To grow, it needs experienced, hands-on fund managers, and those are in short supply, particularly in areas with the greatest needs, such as sub-Saharan Africa.
