It’s not easy to combine all those passions but Marangu has managed to strike a good balance.

Marangu is the co-founder of Mall Networks, an affiliate that builds shopping portals tailor-made for affinity organizations such as school districts, charities, sports teams and consumer associations.

The company, which was formed in 2005, already has a handful of private-label online malls. One of the most recent ones includes a fundraising mall to support Epilepsy research at ( But Mall Networks isn’t just about dealing with nonprofit organizations; it provides professional services as an affiliate to for-profit business including NASCAR and The Los Angeles Dodgers. For NASCAR, built the NASCAR Racepoints’ Online Mall (

“A lot of our clients are strong brands with large customer bases. The bread and butter of our business is going to come from partners like NASCAR or MLB – including the Dodgers. Loyalty is important and enhances those kinds of efforts.”

Maybe that’s why Marangu, always the team player, notes that his two favorite sports or teams are NASCAR and the LA Dodgers.

Marangu helped start Mall Networks in mid-2005 several months after being introduced by a mutual friend to David Andre, the company’s president and CEO. Andre, a performance marketing veteran, was formerly the founding chief technology officer of Upromise, one of the largest consumer loyalty programs. Prior to developing and implementing the business model for Upromise Online Shopping, he was vice president of engineering at Lycos and Direct Hit (acquired by Ask Jeeves).

The two bonded over a shared love of performance marketing, online shopping malls and the ability to provide services to organizations that didn’t have the resources.

“Working in the performance marketing arena is something that I’m very comfortable with. I like working on projects that deliver measurable results.”

At the time, Marangu was running his own consulting business, called Seaspray, so he had the freedom to go out and start something new when the opportunity arose. Andre’s idea for Mall Networks was already in advanced discussion regarding funding by the time Marangu joined the company.

Once on board, part of the challenge for Marangu was getting buy in from merchants. “It was a little chicken and egg problem. Affiliates don’t get approved by merchants without a website to point people to. Yet it was impossible to put up an online mall with merchants. It was an infinite loop we had to break through.”

But Marangu’s past experience and relationships he had previously established in the performance marketing and affiliate marketing space paid off. He was able to get a core group of merchants to sign on, which then led to other merchants coming on board. The company also works with the big affiliate network players including LinkShare, Performics and Commission Junction.

As of early February, Mall Networks had grown to eight employees. Marangu lives just a few miles from his Burlingame, Calif. office. But he is the sole Mall Networks’ worker in the office suite. Still, he shows up every day dressed in business attire ready to tackle his workload. He could work from home, but likes the idea of going into an office.

When he isn’t traveling to the company’s Lexington, Mass. headquarters or other locales for business, he’s up by 7 a.m. and off to the office to “track down an East Coast client.” He keeps in constant communication with his team using Skype and email. He also travels to the East Coast at least once a month. Marangu thinks that being so far apart “is a crucial reason to show up physically every month” in the main office.


Marangu started off his professional career with a Stanford M.B.A. in hand as an investment banker at Morgan Stanley and J.P. Morgan in New York and Australia.

“I’d taken entrepreneurship in business school. I was very interested in being an entrepreneur. I thought that investment banking provided a solid basis of understanding how businesses and business models are developed. It was great for a broad range of understanding the fundamentals.”

Back in 1998, Marangu attended a reunion of business school alumni (he is the current president of the Stanford Business School Alumni Association) in Palo Alto, Calif. At that event he had an opportunity to catch up with a lot of his classmates who had joined or started Internet companies. “That time was ripe to join a venture. Many people I knew had taken the plunge,” Marangu says.

Not long after that gathering he relocated from New York City to the San Francisco Bay Area and joined as Director of Business Development. is an online resource that allows shoppers to research local specials and sale items at stores close to home. Just by typing in their ZIP code, shoppers can search by product category, store or brand name. The venture is now part of ShopLocal, which is the result of a partnership by newspaper giants The Tribune Co., Knight-Ridder and Gannett Inc.

Marangu then moved on to be the General Manager of, a school fundraising company that connects schools and merchants together in a loyalty program. He was brought into the company by a former colleague who ran SchoolPop’s business development and merchant relationships for the online mall.

Not unlike many online ventures of that era, the website and the business were well under way; but Marangu says, the “revenue model needed a closer look.”

What he found was some good news and some bad news.

“On the good side, there was a strong metric among the consumers, high conversion rates and high order rates,” Marangu says. “The bad news was that SchoolPop was not getting full credit with the merchants for delivering the shoppers. We were getting paid a basic affiliate rate and in 2001 that was, relatively speaking, a pittance. The online marketing money was still going to the big portal deals. Affiliates were the last at the table to get budget allocated to them. The commission rates were quite low and not very substantial.”

Still, during his tenure, Marangu developed and deployed SchoolPop’s business model, which delivered over $250 million in trackable multichannel sales to merchants, and as a result raised millions to support public and private schools in every U.S. state.

After three years, in 2003, Marangu left to form his own consulting business with clients including Apple Computer’s online store, where he ran the affiliate program and helped grow it to become one of the largest in the industry. He also designed, negotiated and implemented search and comparison shopping partnerships with Google, Yahoo Shopping, BizRate/Shopzilla, Overture, and PriceGrabber.

Outside Interests

But before going out on his own, Marangu took a much-deserved vacation to Africa. Although he was born in the Midwest, he had attended high school in Kenya, before returning to the United States to go to college at Vassar in Poughkeepsie, New York. His parents still live in Kenya and although he hasn’t been back there since he took his family for that trip in 2003, it’s one of his favorite places in the world.

Years before that trip back, he had deferred his admission to business school to spend a year serving a special assistant to renowned paleoanthropologist and environmentalist Dr. Richard Leakey at the Kenya Wildlife Service, who, at the time, was leading the war on poaching.

For Marangu, who is a wildlife conservationist, it was “a once in a lifetime experience” to work with a figure often described as one of the most controversial, influential and inspirational figures in African politics and world conservation.

Marangu’s job with Leakey came at a crucial time as the conservationist successfully campaigned for a worldwide ban on trading ivory. This huge achievement was symbolized memorably when Kenya’s President Moi set a

mountain of ivory tusks on fire.

“I got the opportunity to work on a number of projects that were constructive in nature [such as] being able to prepare proposals and budgets for World Bank projects,” Marangu says. “We were able to help fund water, school and nursing facilities for communities near the national parks.”

He was also involved in negotiating lease agreements for lodges in Kenya’s national park, which were paying outdated rates, which were not in line with the hefty prices they were charging Western tourists. “They were not paying for the benefits they were getting for security and other services.”

He was also responsible for changing antiquated ticket pricing for the national park.

“If you compare how much one would spend to go to the zoo and what was being charged for two whole days inside a wildlife national reserve in Kenya, it was a pittance by comparison,” says Marangu, who notes that under his plan the entrance fee for locals was not raised. ‘I wanted to encourage the local population to enjoy the reserve.” Aside from the lure of working with Dr. Leakey, there were many things that attracted Marangu to that position.

“I had been away from Kenya for several years and I really want to try and contribute to the well being of the country and help the environment and saving wildlife,” he says.

However, these days his interaction with wildlife is limited to weekend trips to the San Francisco zoo with his wife and three children (aged 5 and under), where they are members. While he prefers to see animals in their natural habitat, Marangu enjoys spending the time with his family.

Marangu says, the lessons he learned early on working in Kenya and in his previous jobs are all very applicable to affiliate marketing. “The most important things are integrity, responsibility, transparency and accountability.”
