Ignition Partners added two high-profile names to its roster, including former Microsoft chief information officer Jim DuBois. DuBois and Datasphere CEO Satbir Khanuja will serve as “venture advisors” at Ignition, a Bellevue, Wash.-based venture capital firm that’s backed companies such as Splunk, Docker, Icertis and Tempered Networks.

“I joined Ignition Partners because I have great respect for their team and I believe in their mission: Ignition aims to be a transformative partner for the companies in which it invests,” DuBois said in a statement. “Adopting their mission as my own, I will deploy my time, contacts, experience and expertise to help Ignition’s founders succeed.”

DuBois began his career at IT company Accenture and later spent 24 years at Microsoft. He served as both a general manager and vice president in the company’s IT and product divisions before becoming CIO in 2013. He left the company in 2017 but continues to work in the tech sector as an author and adviser.

Khanuja is currently the CEO of web hosting service DataSphere.com and has previously held executive roles at Amazon and Amazon-owned IMDB.com, including spending a year as Amazon’s VP of worldwide traffic.

“I’ve enjoyed a close relationship with Ignition Partners since they led the Series A for Datasphere. As a former portfolio company CEO, I’m excited to ‘pay it forward’ and share what I’ve learned with companies that are still in the early stage,” Khanuja said in a statement.

The firm is led by partners including former Microsoft CFO John Connors; Nick Sturiale, formerly of Icon Ventures; and Bob Kelly, who most recently served as corporate vice president for the cloud + enterprise business development and strategy team at Microsoft. In July of last year, Ignition Managing Partner Frank Artale resigned after allegations of “misconduct.”

— Amazon is losing yet another high-powered executive: The company’s VP of voice and natural user interface shopping, Assaf Ronen, recently joined Uber as VP of product, according to a report by Recode. He replaces former Twitter and Google executive Daniel Graf, who served as the head of product at Uber for just more than a year.

Ronen’s departure comes just days after longtime Amazon executive Greg Greeley left the company for a position at Airbnb. His move to Uber is also indicative of the company’s increased ties to the Seattle area following the appointment of former Expedia CEO Dara Khosrowshahi as Uber’s new CEO.

Ronen joined Amazon in 2013 to head its voice efforts. He was previously a general manager at Microsoft, managing groups across the tech giant’s consumer divisions. His new role at Uber is an influential one as the company grapples with a significant number of changes in senior leadership following several scandals, including accusations of rampant sexism and the unveiling of secret, legally questionable programs.
