Business Angel

As an investing member of the Sophia Business Angels (Sophia Antipolis France) Marilyn was one of the founders of the Venture Academy, formed to coach entrepreneurs to become investment ready. The SBA Venture Academy hosted an international group of entrepreneurs from Saudi Arabia, Turkey, Spain, Bahrain, France, Russia, and UK as well as from France.

Marilyn coached entrepreneurs to move a great idea through the process of team selection, business model formation, presentation development and eventual delivery of their “pitch” to angel investors.

Start up Entrepreneurial Story

Marilyn has experienced firsthand the thrills and challenges of entrepreneurship. In the early 1990s with her late husband, Michael Rogosin, founded Whycroft Industries, designing, manufacturing and marketing a dog walkers' accessory, Bagtime.

Bagtime won the Best New Product award at the National Pet Supply Trade Show. There was great interest from buyers at the trade show as well as excellent press coverage, including articles in the Washington Post and the Boston Herald.

They launched the first pet supply “shopping mall” on the Internet and gave seminars on Internet shopping opportunities at the National Pet Supply Trade Show. Their innovative Whycroft offered a mall with boutiques from an international client base.

But it was not a sustainable business model.

Marilyn and Michael moved to Europe to take up positions with firms

that left them no time to maintain Whycroft. They discontinued

operations and distributed the large inventory to charitable

organizations in Boston.

Some of the mistakes they made are common to many of the

entrepreneurs that Marilyn coaches.

They thought that winning prizes and getting great press coverage

made the business viable – but they were wrong.

They thought that large scale manufacturing in China in was a good

idea. Manufacturing prices dropped dramatically. However there

were unanticipated quality issues,  challenges of storage of the large

quantities of product, and distribution problems.

In addition to painful leaning experiences, Marilyn and Michael had

the feeling of what it is like to be totally engaged, “working in the flow”

entrepreneurs – loving what  they did, crafting the best possible

working and environmental practices, and ignoring current realities

of the business model.

The many learning experiences with Whycroft continue to inform

Marilyn's entrepreneurial coaching and judging work today.
