Craig Newmark, the 71-year-old retired founder of Craigslist, has four focus areas for philanthropy: military families and vets, cybersecurity, journalism, and pigeon rescue.

On Wednesday, he pledged $100 million to support U.S. cybersecurity, bringing his total giving and pledges to $400 million since 2015.

According to the Wall Street Journal, Newmark has already committed over 20% of the $100 million pledge to organizations and projects around cybersecurity. Common Sense Media, for example, received $2 million to support efforts like a cybersecurity awareness campaign for parents and teachers.

Newmark was worth $1.3 billion in 2020 and pledged to give away almost all his wealth to charitable causes in December 2022. He told the Journal that his giving was inspired by the Judaic concept of tikkun olam, Hebrew for “repairing the world.“

Newmark’s approach is to find the right people, give them the resources they need, “and then get outta their way,” according to his philanthropy’s website. He doesn’t give organizations who receive grants requirements to hit certain targets.

Newmark has yet to commit $88 million of his latest $100 million pledge. Applications are open through his foundation’s website where he personally vets the proposals.

Days after proposing to settle a data breach lawsuit for $30 million, 18-year-old genetic testing company 23andMe now faces another public hurdle: Seven independent directors of its board resigned on Tuesday through a pointed letter addressed to CEO Anne Wojcicki, who is now the only remaining member of the board.

The resigning directors, among whom were YouTube CEO Neal Mohan and Sequoia VC Roelof Botha, called out Wojcicki for not submitting a “fully financed, fully diligenced, actionable proposal” to take the company private over the past five months. They wrote that their strategic direction for 23andMe was different from Wojcicki’s.

“Because of that difference and because of your concentrated voting power, we believe that it is in the best interests of the Company’s shareholders that we resign from the Board rather than have a protracted and distracting difference of view with you as to the direction of the Company,” they stated.

Wojcicki, who co-founded the company in 2006, controls 49% of 23andMe votes. In July, she submitted a proposal to buy all the shares she didn’t already own at $0.40 per share and take the company private. A special committee created by the company rejected her proposal, stating that it wasn’t in the best interests of shareholders.

Wojcicki told employees in a memo on Tuesday that she was “surprised and disappointed” by the resignations and would immediately begin finding replacement directors. She stated that “taking 23andMe private will be the best opportunity for long-term success.”

23andMe, which was valued at $6 billion in 2021 shortly after going public, is now a penny stock worth 34 cents per share at the time of writing. The company has until November 4 to bring its stock price up to at least $1 per share or risk being delisted.

23andMe has faced a number of public setbacks, including a data breach in October that impacted nearly 7 million accounts and appeared to target people with Chinese or Ashkenazi Jewish ancestry. Customers filed a class action lawsuit in January and 23andMe proposed a $30 million settlement earlier this month.

23andMe’s core product is a $99 ancestry kit that requires a customer to submit their spit in exchange for genetic insights. A $199 kit advertises health predisposition reports. The company is also developing drugs in-house and testing them.

As the co-founder and former CEO of Yum! Brands, one of the world’s largest restaurant companies with a portfolio including franchises like KFC and Pizza Hut, David Novak drove tangible results.

In the 17 years he was CEO, from 1999 to 2016, Novak helped scale the company to eight times its original size, from a market capitalization of $4 billion to $32 billion. However, Novak credits the numbers to a more qualitative than quantitative aspect of leadership — creating the right work culture.

In a conversation with Masters of Scale host Jeff Berman that aired earlier this month, Novak explained how he steered Yum! Brands from the beginning.

“I made my number one priority to really create a powerful culture where everyone counts,” Novak said. “That became job number one for me as a CEO, because if I can create that right work environment, people will innovate and people will go further.”

Novak explained that early on, he tried to learn from companies that were winning or consistently delivered good results. He went out and visited companies including Walmart, Home Depot, and General Electric.

“We met with them,” Novak said. “Then we came back and we codified what’s really driving the success of these companies that allow them to get to great results year after year.”

Novak, who oversaw 1.5 million employees globally, began emphasizing recognition and encoding it into Yum!’s culture. In previous interviews, he talked about how he would use recognition to motivate employees. In one case, at KFC, Novak gave away rubber chickens and $100 as an award for a job well done.

Today, Yum!’s culture remains one of recognition and collaboration, per its public-facing culture page.
