Meet the Team

  • Sean Im

    CEO

    I was born in Seoul, Korea, and grew up following my diplomat parents to new destinations every three years. My early years were spent in Asia, later in South America, and the remainder in North America and Europe. This unique upbringing has given me a broad perspective on the world and who I am today. I am grateful to my parents for providing me with this enriching experience.

    My entrepreneurial journey began in high school in South America, where I transformed one of my father’s living rooms into a startup hub. I placed a newspaper ad offering consulting services to small Ecuadorian businesses on setting up PC-based operations. The venture’s success led me to hire my younger brother, and it sparked a lifelong passion for launching successful businesses.

    Over the past three decades, I’ve had the privilege of working in the technology industry. My early career was shaped at Accenture, later becoming a partner at PWC consulting. I then spent a decade as an executive at IBM, driving growth for our top 100 accounts in North America and Asia Pacific. Most recently, I spent ten years at Samsung SDS, the technology arm of Samsung. I started as Chief Strategy Officer and progressed through senior leadership roles in global business development, solution and IT services, culminating in my position as CEO of our $2B North America business.

    What drives me is creating businesses that endure. Today, technology is no longer just a support system for a company’s strategy; it defines it. I joined Delta-v because it offers me the opportunity to collaborate with exceptional talent and combine capital, technology and entrepreneurship to build something that leaves a lasting impact.

    The business leaders that I admire most are not household names. Instead, they are the incredible entrepreneurs and CEOs I’ve worked with over the years. These leaders have become friends with whom I’ve shared life shaping experiences. We’ve shared in successes and disappointments, both personally and professionally. Fundamentally, we value treating people right, serving our customers, and building great, lasting companies.

    The meaning behind “Delta-v” is the total effort required to change from one trajectory to another. Nothing fuels me more than helping management teams build their company into a highly scaled, durable business.

    When I co-founded Delta-v in 2009, our strategy was novel. We focused on providing liquidity for minority shareholders in great companies (ie secondary directs). Today, we support teams with both secondary liquidity and primary capital (ie cash on the balance sheet). The evolution of Delta-v and our strategy is similar to the evolutionary path many of our portfolio companies have traced. In 2009, secondary directs was a nascent, unproven market. It took perseverance, steadfast belief in our true north, and grit to build the team into the institutionalized growth equity firm that we are today.

    Before Delta-v, I was a partner at Centennial Ventures. I learned so much about investing in great companies during the dot-com bust of 2001 to 2003. In 2008, Centennials’ founders were retiring, giving me the opportunity to create something of my own. I had conviction that innovation would continue to march forward during and after the financial crisis, and that revolutionary tech companies led by great entrepreneurs would emerge.

    Since the founding of Delta-v, we’ve partnered with technology companies that I am truly honored to be associated with and whose success I'm proud to have played a role. I remain as excited today as I did then, to creatively, flexibly, and humbly support the next wave of category-defining companies.

    While my childhood included many of the classic entrepreneurial experiences (think lemonade stands, paper routes, and starting my own lawn care business), my first professional experience was a summer job at the Cleveland Clinic. Working in the radiology department, I developed a taste for using technology to solve inefficiencies.

    I attended the Wharton School of Business at the University of Pennsylvania, graduating summa cum laude as a Joseph Wharton and a Benjamin Franklin Scholar. I finished in five semesters, led by an aha moment that the school charged by the semester and not the credit hour.

    I went on to Commonfund, a pioneer in developing the endowment model of investing on behalf of nonprofit institutions. We were helping world-class, institutional LPs and evaluating high-growth, innovative technology businesses.

    I joined Delta-v because it offered me the opportunity to work with a growing platform of investors who share my values and support my approach to investing. I partner with existing growth-minded management teams of cloud services and vertical software companies, and support growth initiatives and strategic acquisitions designed to drive long-term value. I often apply a buy-and-build methodology leveraging Delta-v’s sector expertise and operational capabilities. My job is to know what we know, and do it well, on behalf of our limited partners and portfolio companies.

    My investment philosophy is to invest in people first and foremost. I believe that the strongest companies of tomorrow will have exceptional leaders, low attrition, career paths for employees, and an inclusive culture.
