This Private Equity Investor-Turned-Founder Raised $25 Million To Solve Energy Access For 3 Billion People

Bill Lenihan’s entrepreneurial path didn’t start as an engineer, product builder, or early startup operator. Instead, his career began in the structured world of finance—investment banking and private equity—before evolving into technology operations and eventually entrepreneurship.

Today, Bill Lenihan is the Founder and CEO of ZOLA iNTELLIGENCE (ZOLAi), a company building agentic technology platforms to bring reliable, affordable energy to billions of people in emerging markets.

Bill’s story illustrates how diverse career experiences—from Wall Street finance to operational leadership—can ultimately converge into a mission-driven entrepreneurial journey focused on solving one of the world’s largest infrastructure challenges.

Growing Up in Southern California

Bill Lenihan grew up in Whittier, California, a smaller town located east of Los Angeles. His upbringing in Southern California exposed him early to diversity, community, and opportunity. He describes his childhood as grounded in a supportive family environment.

Bill had two sisters and parents who encouraged growth and ambition. Athletics also played an important role in shaping his mindset. He began swimming at a young age, later adding water polo in high school, and playing both sports through college at UCLA.

Water polo became an important formative experience. The sport reinforced teamwork, discipline, and competitiveness—traits that would later prove invaluable throughout his professional career.

After high school, Bill attended UCLA, beginning a journey that would eventually lead him into the world of finance and global business.

Starting a Career in Investment Banking

Like many future investors and operators, Bill’s professional journey began on Wall Street. After graduating from UCLA, he joined Credit Suisse as an analyst in the investment bank’s Mergers & Acquisitions (M&A) group.

Working in M&A exposed Bill to complex transactions and corporate strategy at the highest levels. It also gave him a front-row seat to the world of private equity. Many of the deals he worked on involved private equity firms acquiring businesses, requiring financing, and transforming them through strategic improvements.

Bill became fascinated by that model. Private equity firms were not simply financing companies—they were evaluating operations, improving strategy, identifying viable opportunities, and unlocking value. This blend of finance and operations deeply interested him.

However, at the time, private equity firms were not actively recruiting directly from investment banks. Bill realized that to transition into private equity, he would likely need an MBA. So, he enrolled at The Wharton School, one of the world’s leading business schools.

While pursuing his MBA, he intentionally structured his academic focus around the combination of skills required for private equity. He pursued a concentration in operations, general management, and finance, recognizing that investing in companies requires these disciplines.

Private equity, after all, involves evaluating how businesses operate and determining how they can improve. At Wharton, Bill leveraged the school’s powerful alumni network to build relationships with private equity professionals.

Those relationships ultimately led to an opportunity to join Goldman Sachs’ private equity practice.

Fifteen Years in Private Equity

Bill spent nearly 15 years working in private equity, beginning at Goldman Sachs and later joining Fremont Partners. His career eventually brought him to San Francisco, where Fremont Partners operated with a distinctive investment philosophy.

The firm was backed by the Bechtel family who built Bechtel Corporation, a 100+-year-old, fourth-generation family management organization. It was well-known for building some of the most complex infrastructure in the world. This heritage shaped Fremont’s approach to investing.

Rather than focusing solely on financial engineering, the firm prioritized operational improvement and long-term value creation. Their central questions were simple but powerful:

• What risks exist in the business today?
• How can the company become stronger in the future?
• What operational changes will unlock growth?

This operating-oriented approach resonated deeply with Bill and further shaped his perspective on business. But eventually, a new opportunity emerged—one that would shift his career in a completely different direction. At that point, Fremont Partners became Calera Capital.

Crossing the Table: From Investor to Operator

After years in private equity, Bill was invited by an operating partner from Calera to join a technology company called Switch in the Bay Area. The company’s CEO believed Bill possessed something many investors lack: an interest and potential skill in general management and operations. At the time, he was about 40 years old.

Bill realized that if he ever wanted to experience the operating side of business, the moment had arrived. He decided to take the leap. His reasoning was simple: even if the experiment failed, becoming an operator would likely make him a better investor.

Bill kept his options open—maybe he could go back to private equity. What he quickly discovered, however, was that operating a company requires an entirely different skill set.

The Reality of Being an Operator

Many investors believe they would excel as operators. Bill admits he initially thought the same. But the transition from a financial investor to operator and founder of ZOLAi revealed how different the roles truly are.

However, gaining the investor perspective and education centered on making and optimizing for profitability made a huge difference. Bill had learned that EBITDA and growth are everything in private equity.

Investors operate with a broad perspective. They must understand pattern recognition when evaluating multiple companies, analyzing across business models, and assessing risk across portfolios. Their task is very data-oriented.

Operators, on the other hand, must focus deeply on execution within a single organization. Bill views both as very different skill sets, but also complementary. The job involves building teams, structuring organizations, setting operational targets, and managing execution day after day.

Bill quickly realized that success as an operator depends heavily on organizational development. Strategy matters—but the ability to organize people around that strategy matters even more. Despite the steep learning curve, his PE background proved invaluable in one critical area: capital allocation.

Capital Allocation: The CEO’s Most Important Skill

Bill believes that one of the most important responsibilities of a CEO is allocating scarce capital effectively. Early-stage companies have limited resources. Every dollar must be directed toward the highest-return, lowest-risk opportunities.

These decisions might involve funding a new product initiative, expanding into a new market, hiring key personnel, and investing in technology infrastructure.

Private equity experience and the analytical capabilities he had developed sharpened Bill’s ability to evaluate these trade-offs using data and financial discipline. He considers it highly beneficial because he learned pattern recognition for determining whether initiatives would be fruitful.

But after spending 15 years as both an investor and an operator, a new opportunity would soon emerge—one that would define the next chapter of his career. By this time, Bill was ready to embrace the other side of the table, from being an investor to going at it on his own.

Discovering a Global Energy Crisis

Bill eventually encountered a company called Off Grid Electric, which would later evolve into ZOLAi. It was his first role on the operations side of the technology. As he reveals, he enjoyed the organizational dynamic of a company relative to a private equity firm.

Bill had been looking for a specific role, such as a COO or a CEO, and a specific technology-driven company. Most importantly, he needed it to be big and impactful. Off Grid Electric fit the bill because it was a renewable energy company and tackling a worldwide problem.

At the time, the company operated in Africa, installing small solar systems and lithium-ion batteries in rural communities and among off-grid farmers in the Serengeti who lacked access to reliable electricity. Essentially, it was doing IoT distribution.

Users were displacing kerosene lanterns with small connected devices that required mobile payments. Initially, Bill was unsure whether the opportunity was right for him. He had little experience with Africa, renewable energy, or rural infrastructure.

But before making a decision, Bill traveled to Africa to see the business firsthand. That trip changed everything.

The Moment That Changed Everything

During his visit, Bill witnessed something that left a lasting impression. He encountered a massive problem that needed solving. The impact: three billion people lacked reliable, affordable energy. The solution was relatively unique to those markets.

The main competitor here was kerosene, and the company was installing small, connected devices to generate energy for farmers—an entirely unique concept.

From a private equity perspective, it was unclear whether there was any return on investment or capital in the business, or whether it was sustainable. In fact, it was far from being sustainable at the time. But then Bill had firsthand experience of how the system worked.

The team had installed a solar-powered system capable of running a television in a small rural home. One evening, after fixing a malfunctioning unit, they switched the system on. The hut lit up in the darkness. Within minutes, the entire community gathered around the house.

Children played outside while adults gathered inside to watch television and socialize. For the first time, the home had reliable light and power. That moment revealed something powerful. Energy access wasn’t just about electricity—it was about transforming lives and communities.

Bill realized he had discovered a mission worth pursuing. What he initially thought might be a two-year short-term experiment turned into a decade-long commitment.

The Birth of Zola Intelligence

As Bill explains, ZOLAi is a mission-oriented company. He strongly believes in the mission and in their ability to change the world. Ultimately, it transitioned from distribution IoT to its current model—an agentlc enterprise technology platform.

Now, ZOLAi is an enterprise company that sells technology to companies of all sizes to solve on-the-ground energy problems in their countries.

Bill reveals how he quickly realized that the hardware distribution model, even if it was IoT, could be a problem. The grid was unreliable, and gaps were bridged using diesel generators, inverters, batteries, solar panels, and other hardware.

Close to 80 countries and 3 billion people worldwide relied on them for energy. The grids and hardware distribution model didn’t have any return on investment (ROI), and the customer experience was terrible, as Bill realized.

Distributing hardware—solar panels, batteries, and inverters—had its limitations. It was not enough to solve the energy problem in emerging markets. The result is often an inefficient and expensive energy ecosystem.

Bill’s vision was to shift the industry away from hardware distribution and toward Energy-as-a-Service. They had the technology—all it needed was funding.

Building Agentic Energy Platforms

Three years ago, Bill raised $20M to build a new enterprise technology platform. That platform now powers ZOLA iNTELLIGENCE. Rather than selling hardware directly, ZOLAi provides a comprehensive technology platform that enables companies to deliver energy as a service.

Storytelling is everything that Bill was able to master. The key is capturing the essence of what you are doing in 15 to 20 slides. For a winning deck, take a look at the pitch deck template created by Peter Thiel, Silicon Valley legend (see it here), where the most critical slides are highlighted.

The ZOLAi platform consists of three layers:

1. Hardware Infrastructure: Batteries, inverters, and connected devices that generate and store energy.
2. Control Layer: Software that manages and optimizes energy systems.
3. Application Layer: Enterprise tools that allow companies to manage operations, workflows, and customers.

One of the platform’s most powerful features is its use of agentic software systems. Zola’s customer companies don’t just sell hardware to consumers; they sell leases or energy-as-a-service. Consumers pay for energy, just as users in the US, without worrying about maintenance issues.

For example, Zola’s underwriting agents can automatically assess whether customers qualify for energy financing. These systems evaluate customer identity (KYC), credit information, and risk profiles.

The platform can then approve financing and price the energy service to ensure sustainable returns. This dramatically improves efficiency, reduces defaults, and allows companies to scale energy services in emerging markets.

The principle is simple. If energy companies are going to solve the problem of expanding energy access for 3 billion people, they have to have an ROI.

The Challenge of Raising Capital for Emerging Markets

Raising capital for ZOLAi required a very different strategy than that of typical venture-backed startups. Emerging-market infrastructure projects require patient, risk-tolerant investors.

Bill underscores that, as this is deep technology, it takes a lot of time. He needed to be intentional about securing capital.

He focused on identifying investors who understand emerging markets, believe in long-term infrastructure investments, care about global energy access, and are aligned with the company’s mission. In short, they needed to be technology and mission-oriented.

This intentional investor selection process allowed ZOLAi to secure the funding required to build its platform. As Bill points out, if you can “find that specification of investor, then you’ve got a good business model, because the opportunity obviously is what drives the investment.”

A Vision for the Future

Bill envisions a future in which energy distribution across emerging markets is powered by major service companies, such as telecommunications or Energy Service providers. He explains that telecom operators tend to be the biggest, most profitable companies in their countries.

These operators already provide critical infrastructure in many developing economies by delivering connectivity, mobile payments, and financial services. They provide the most needed service and deliver an exceptional experience for customers.

Now, through partnerships with ZOLAi, they may also deliver energy services. Bill recently secured a partnership with a telecommunications company that will integrate Zola’s technology into its platform.

If ZOLAi succeeds, similar partnerships could expand across 80 countries where reliable energy remains scarce. In addition to driving data, connectivity, and payments in their country, they will also drive energy-as-a-service for their country and all their customers.

The goal is clear: Deliver reliable and affordable energy to three billion people worldwide.

Advice to His Younger Self

Looking back on his career, Bill offers three key lessons.

1. Trust Your Instincts: If you believe you are suited for operating or entrepreneurship, trust that intuition.
2. Be Patient Finding the Right Opportunity: Unlike private equity investors who build portfolios, operators get one opportunity at a time. Choosing the right one matters.
3. Align with a Mission: The most successful operators are driven by purpose and passion for the problems they are solving.

When these elements align, the chances of success increase dramatically.

A Mission Worth Pursuing

Bill Lenihan’s journey—from investment banker to private equity investor, from operator to founder—demonstrates how diverse experiences can converge into a mission-driven entrepreneurial path.

Today, through ZOLA iNTELLIGENCE, he is working to solve one of the world’s most important infrastructure challenges: reliable energy access. For billions of people across emerging markets, that solution could transform entire communities.

Just as Bill witnessed in that small village years ago, when a single light illuminated the night.

Listen to the full podcast episode to know more, including:

• Trust your instincts when choosing between investing and operating if you feel drawn to building companies.
• Patience is critical because operators often have only one major opportunity, unlike investors managing portfolios.
• Finding the right opportunity matters more than moving quickly into the wrong one.
• A founder’s career is often a “rifle shot,” requiring focus on a single mission rather than diversified bets.
• Passion and belief in the mission are essential to sustain the challenges of building a company.
• Alignment between skills, patience, and purpose significantly increases the odds of success.
• Without conviction, patience, and mission alignment, the entrepreneurial path becomes far riskier.
