Kenandy has 100 employees and is tripling annual revenue as businesses move their enterprise resource planning applications to the cloud. Notable customers include Big Heart Pet Brands (formerly Del Monte) and Philips.
Kurtzig came out of retirement to start the Redwood City, California-based company in 2010, some 38 years after founding her first business ASK Group. ASK's software helped manufacturing companies manage their operations.
She built ASK to $400 million in revenue. It was eventually sold to Computer Associates (now known as CA), though the company was suffering from mounting losses by the time of the deal. Kurtzig left before the sale.
While she declined to provide her net worth, Kurtzig said that she would rank high on Forbes Magazine's recent list of the 50 richest self-made women, if her numbers were public. The list ranges from $250 million to $4.5 billion, with 18 billionaires at the top.
One distinction Kurtzig will always have is being the first woman to take a Silicon Valley tech company public. She led ASK's IPO in 1981.

"She had a fantastic career, sold her company and basically retired," said Marc Benioff, the founder and chief executive of Salesforce.com, which invested in Kenandy to help get it off the ground. "She decided to do it all again. It's very cool."
Not that Kurtzig was ever really out of tech.
Her two sons, Ken and Andy (the inspiration for Kenandy), are themselves successful technology entrepreneurs, who have worked with their mother in formal and informal ways.

Andy, 42, is the founder and CEO of JustAnswer, a question-and-answer site that attracts 26 million visitors a month. Ken, 39, founded cloud software maker Arizay (named after his two kids, Arie and Alizae) in 2013 and previously started iReuse, whose software helps companies run sustainability programs.
The three worked together for a brief stretch from 2000-2001 at eBenefits, a human resources software company, where Andy was chief executive, Sandra (who goes by Sandy) was chairman and Ken was a product manager.
In her second go-round as a founder and CEO, Kurtzig said she has observed an environment with much more focus on gender, even though the numbers haven't improved dramatically. According to the Kauffman Foundation, fewer than 10 percent of high-growth companies are founded by women.
