News on portfolio companies and acquisitions
We look for companies with strong or niche market positions that can benefit from a more structured, institutional foundation. Our approach is to partner with founders and support management in driving long-term value.
We’re hands-on where it counts—not in the day-to-day, but in unlocking growth through strategy, business development, and our deep network of institutional relationships.

About:Kingchih Fan (‘KC’) is an adjunct professor at NYU Stern School of Business, where he teaches Entrepreneurship through Acquisition, a course focused on finding, valuing, and acquiring an existing business. He is an entrepreneur, investor, and operator with extensive experience in private equity, growth marketing and technology entrepreneurship.
KC is a founder and General Partner at The Buy Build Fund, a firm that focuses on acquiring cash flow-positive companies and enhancing their value through digital transformation. The firm’s partners have collectively invested in over 100 companies.
iGOTHAM owns equity in a number of businesses with combined annual revenues exceeding $100M. The company leverages AI, technology, and automation to accelerate the acquisition process.
Previously, KC served as an Operating Partner at The Riverside Company, a $10B private equity firm, where he worked on growth marketing and scaling B2B SaaS portfolio companies. Prior to this, KC was the Chief Business Officer at SIB Fixed Cost and led Venture Capital Engagement in New York for Microsoft.
KC co-founded LiftDNA, a technology company that commercialized a programmatic advertising process which allowed publishers to sell ad space in real time. LiftDNA was bootstrapped and reached $10M in gross revenue within 2.5 years before merging with OpenX.
We’re a fit for founder- or family-owned companies facing succession planning, teams seeking growth or partial liquidity, and underperforming businesses with operational or financial complexity. Our sweet spot includes buyouts, recapitalizations, corporate carve-outs, and special situations where we can add value through strategy, business development, and our institutional network.
What sets us apart is our operator-first mindset and deep experience across both entrepreneurship and institutional investing. Our founder, Kingchih Fan, is a serial entrepreneur and former Operating Partner at The Riverside Company, with a track record that includes building and exiting companies like LiftDNA and investing in businesses such as OpenX and SIB Fixed Cost Consulting. That blend of founder empathy and private equity discipline runs through everything we do.
We take a partnership-first approach—working closely with founders and management teams as strategic allies, not just capital providers. We focus on alignment, long-term growth, and unlocking hidden value through thoughtful structure, digital enablement, and business development. Our acquisitions reflect this: strong niche businesses ready to scale with the right partner beside them. We’re not here to just own a company—we’re here to build with you.
We know that for many owners—especially those running family-founded businesses—the sale process can feel overwhelming and deeply personal. That’s why we’ve designed our acquisition process to be low-disruption and high-trust, with the goal of making the experience additive, not exhausting.
It all starts with a no-pressure conversation to explore fit. If there’s alignment, we’ll visit the business, walk the floor, and get a feel for operations firsthand. From there, we move quickly to share a clear indication of interest—centered around the top 2–3 drivers of value that matter most to both sides.
We often bring in trusted partners early in the process—whether for co-investment, operational expertise, or strategic alignment—but always under strict confidentiality to protect the integrity of the process and the business.
Once aligned, we move into an exclusive letter of intent, followed by confirmatory diligence that’s focused, respectful, and tailored to minimize disruption. We’re experienced in working with first-time sellers and pride ourselves on being transparent, thoughtful partners every step of the way.
We don’t get involved in the day-to-day unless absolutely necessary—but we’re deeply engaged where it matters. Our role is to support management in executing the investment strategy and unlocking long-term value.
We give leadership teams the freedom to run the business while offering hands-on support when needed—whether it’s acting as a strategic sounding board, helping evaluate growth opportunities, recruiting key talent, or driving specific initiatives.
Our involvement often leads to measurable gains in business development, cost savings, operational efficiency, financial reporting, banking relationships, and governance.
From day one, we bring a strategic lens to the table. That might mean introducing a value-add co-investor, bringing on a seasoned board member, or facilitating access to new customers or vendors. We ask tough, unbiased questions during diligence to uncover angles others might miss—and we stay committed as partners long after the deal is done.
