Summit Partners appoints Executive-in-Residence

Summit Partners, a global growth equity investor, has added JD Mullin to the firm’s Executive-in-Residence (EIR) programme. 

In this role, Mullin will work closely with Summit’s technology team to identify new investment and leadership opportunities in growth-stage software companies.

Mullin brings substantial experience in leading and scaling fast-growing SaaS businesses, as well as in building engineering and product teams that help drive rapid innovation and support high-velocity sales models.

Mullin joins Summit’s EIR program from Intuit, where he has led the QuickBooks Time business unit since 2019. He joined Inuit following the company’s acquisition of TSheets, a leading SaaS-based time tracking and scheduling platform, and he helped lead TSheets’ integration with Intuit. Mullin. originally joined TSheets in 2013 as SVP Product and Engineering and played an instrumental role in leading the company through a period of rapid growth. From 2013 until 2021, he helped scale the team from 20 to more than 400 employees, grow annual recurring revenues (ARR) from less than USD1 million through the nine-figure milestone, and expand the user base from 30,000 users to more than 1.8 million. Prior to TSheets, Mullin held engineering roles at WhiteCloud Analytics, SAP, Sybase and Extended Systems.

“We’ve worked closely with JD for a number of years, and we’ve been continually impressed with his rare combination of product vision, technical expertise and business acumen,” says Colin Mistele, a Managing Director with Summit Partners. “During his time at TSheets, he established teams and processes that allowed the company to innovate quickly to meet the demands of its high-velocity go-to-market model. He brought this data-driven, product-led growth mindset to the general manager role at Intuit where he helped scale the business even further. We are thrilled to work alongside JD and share his talents and leadership with other great SaaS businesses.”

“Over the course of my career, I’ve been fortunate to work for two Summit-backed software businesses – working most closely with the team during my tenure at TSheets,” says Mullin. “Knowing the experience, support and resources they bring as a partner to growth companies, I’m incredibly proud to join Summit’s EIR program. I’m very much looking forward to working with Summit to identify a new opportunity where I can make an impact as a leader, scale an organization and navigate a new growth journey.”
