Renée Adams

Head of Operations, Founder

Renée is co-founder and Head of Operations for PullString. Renée's background centers mainly around Program Management where she's worked on a variety of projects for all aspects of business. At Apple Computer, where Renée spent four years, she worked on projects for IS&T, Americas Operations and Logistics, and Retail Development. After leaving Apple, Renée joined Pixar Animation Studios where she spent nearly eight years as part of the Studio Tools software team. While there, Renée headed up the Project Management team on the next generation software effort as well as managed the department budget and hiring. Renée completed her MBA with a focus in Organizational Behavior and Change Management at night while working for Pixar. When she’s not working at PullString, you can find Renée hanging out with her family or shopping for shoes.

The culture of PullString is vibrant and diverse. Engineers and scientists work on AI, NLP and the expansion of our authoring tool. Conversation designers bring to life an array of branded bot and interactive character experiences. Audio engineers record original voice-over performances and mix soundscapes. These teams have been collaborating seamlessly for more than 5 years to pioneer a new era of computer conversation, and the company culture that has emerged is one of constant enthusiasm, creativity, insight and momentum.

Working in the conversation field, it’s been important to us to assemble an office full of thoughtful and respectful communicators. Our culture is one of transparency, trust and support. We enjoy each other's company, work hard to remove each other's roadblocks, and give credit where credit is due.

And, of course, we are a startup: we get free food, have an in-office whisky bar, play Friday afternoon games, and enjoy our off-sites to wine country. But we're also a mature startup -- family friendly -- with an emphasis on work/life balance.
