David Bartenwerfer is a business professional and entrepreneur with over two decades of experience leading companies through transformative growth, primarily by harnessing the power of advanced analytics, technology, and strategic thinking. With a career spanning multiple industries—including real estate, finance, high-tech, professional sports, and private equity—David Bartenwerfer has built a reputation for applying quantitative methods to solve complex business challenges. His expertise in driving profitability and implementing change management strategies has been demonstrated in leadership roles at companies such as The Boston Consulting Group, Charles Schwab, and Verizon.
As the co-founder and Chief Technology Officer (CTO) of REALbasis Inc., David Bartenwerfer has made significant contributions to real estate investing and asset management through the innovative application of predictive analytics and other quantitative methods. REALbasis Inc. assists investors in identifying top-performing markets and cash-flow-generating assets, optimizing investment strategies in an ever-changing market landscape. Alongside his work at REALbasis Inc., he is also the founder and principal of Quantum Consulting and Technology, a firm specializing in business growth and strategy across various sectors.
David Bartenwerfer’s career is marked by a deep understanding of how analytics can be leveraged to optimize business performance. His educational background is a testament to this, having earned a Bachelor of Science degree and graduating at the top of his class in Systems Engineering from the University of Virginia, where he also minored in applied mathematics and economics. He later earned an MBA from Stanford University, further equipping him with the tools needed to drive results in a competitive business environment.
One of the hallmarks of David Bartenwerfer’s approach is his ability to lead cross-functional teams and foster collaboration in fast-paced settings. His work is often focused on the integration of sophisticated algorithms, predictive models, and data-driven strategies to enhance decision-making processes and profitability. Whether it’s optimizing lead management for customer acquisition or using mathematical models to predict market shifts, Bartenwerfer’s influence has been broad and impactful.
In his writings, such as “Customer Retention is Not the End Game,” David Bartenwerfer explores the idea that retaining customers should be about more than just preventing defection. According to Bartenwerfer, understanding customer dynamics at a granular level can offer businesses unique opportunities for growth. He advocates for using analytics to track purchasing patterns, highlighting the importance of acting on early indicators of customer behavior changes. By identifying when customers are either scaling back their spending or increasing their investment, companies can take proactive steps to improve customer satisfaction and revenue retention.
Customer acquisition, another key area in Bartenwerfer’s body of work, also benefits from his analytical approach. In his article “Drive New Revenue Growth with Predictive Analytics,” Bartenwerfer discusses how improving lead management can dramatically increase a company’s ability to capture new customers. He emphasizes the importance of integrating predictive analytics into marketing and sales strategies, enabling companies to more effectively prioritize leads based on potential value and readiness to buy.
By streamlining lead management processes and using data to inform decision-making, Bartenwerfer believes businesses can reduce acquisition costs and increase sales productivity. His strategies aim to help companies not only generate more leads but ensure that those leads are acted upon in a timely and efficient manner, with high-potential prospects receiving the most attention.
David Bartenwerfer’s focus on the quantitative side of business extends to sales strategies as well. In his work on ROI (Return on Investment) selling, particularly in business-to-business (B2B) contexts, Bartenwerfer argues that a product’s value proposition must be clearly articulated in terms of its potential economic return. This approach is especially important for companies offering complex or high-cost solutions, where decision-makers such as CFOs demand a clear business case before approving significant purchases.
According to Bartenwerfer, the key to successful ROI selling is developing tools that allow sales teams to present a fact-based, financial rationale to prospects. These tools, often in the form of ROI calculators, can help sales representatives demonstrate how a product will deliver measurable benefits in terms of cost savings or increased revenue. When implemented correctly, ROI selling can lead to increased win rates, faster sales cycles, and greater confidence among buyers.
However, Bartenwerfer is quick to note that simply having an ROI tool is not enough. The tool must be easy to use, credible, and adaptable to the specific needs of each prospect. By treating the ROI calculator as a product in its own right—complete with training, support, and regular updates—companies can ensure that their sales teams are equipped to leverage it effectively. For Bartenwerfer, the goal of ROI selling is not just to close deals but to build long-term relationships based on trust and demonstrated value.
Throughout his career, David Bartenwerfer has demonstrated an ability to apply his analytical skills to a wide range of industries, including real estate, finance, telecommunications, professional sports operations, and technology. His work at Quantum Consulting and Technology has allowed him to advise companies across these sectors on how to optimize their operations, manage change, and drive growth.
One area where Bartenwerfer’s expertise has been particularly valuable is real estate. At REALbasis Inc., his focus on using data-driven methods to identify high-performing assets has enabled investors to achieve returns that outperform the market. By applying the same principles of predictive analytics and optimization that he has used in other industries, Bartenwerfer has helped bring a new level of rigor to real estate investment strategies.
In addition to his professional accomplishments, David Bartenwerfer is an avid world traveler, having visited over 100 countries. His global perspective and willingness to explore diverse cultures have likely influenced his approach to business, particularly when it comes to understanding the complexities of different markets and industries.
David Bartenwerfer’s career is a testament to the power of analytics in driving business success. Whether through his leadership at REALbasis Inc. or Quantum Consulting and Technology, his work has consistently focused on using data to inform strategy and improve outcomes. With a strong background in engineering, mathematics, and economics, Bartenwerfer has positioned himself as a leader in applying quantitative methods to real-world business challenges.
As companies across industries continue to seek ways to optimize their operations and drive growth, David Bartenwerfer’s insights into customer dynamics, analytical marketing, lead management, and ROI selling will remain highly relevant. His emphasis on integrating data into every aspect of decision-making serves as a reminder that, in today’s competitive marketplace, success often comes down to understanding the numbers behind the strategy.
