The Silver Tsunami: The Crisis in Small Business Ownership
Over the next two decades, a significant demographic shift is set to reshape America’s small business landscape. On October 27, 2025, Joe Lonsdale and Denis Aven of 8VC published an article highlighting this impending “Silver Tsunami,” where over 3 million small business owners aged 55 or older will seek to exit their companies.
The Scale of the Challenge
According to the authors, this wave is estimated at $10 trillion in business value. However, nearly half of these owners have no succession plan, and only 30-40% of those with plans will successfully sell their businesses. This means that many small businesses are at risk of closing their doors permanently.
Impact on Local Economies
The loss of these businesses would have profound implications for local communities. These firms often sponsor community events like Little League teams and provide good-paying jobs, making them vital to the economic fabric of neighborhoods across America.
A Solution: Entrepreneurship Through Acquisition (ETA)
To address this crisis, Lonsdale and Aven propose a new strategy known as Entrepreneurship Through Acquisition (ETA). This approach involves raising capital to find, buy, and run a single business as CEO. ETA offers an alternative to the traditional private equity model, which often prioritizes short-term gains over long-term community impact.
Challenges in Scaling ETA
Despite its potential, ETA has struggled to scale due to several barriers. Rigid criteria, heavy investor oversight, and a bias toward Ivy League backgrounds limit access for skilled operators who have built relevant industry experience through years of work.
Mainshares: A New Platform for Small Business Ownership
Enter Mainshares, an initiative that aims to unlock this new model. Mainshares connects experienced operators with businesses for sale, creating opportunities for aspiring owners and ensuring local enterprises can thrive. The platform supports community involvement by prominently displaying its stickers in small businesses.
Investment Strategy and Goals
Mainshares’ goal is threefold: to access talent, operate as a tech-first company, and foster an aligned partnership structure. By leveraging the expertise of 8VC’s team, Mainshares aims to overcome these structural barriers, making small business ownership accessible at scale.
Key Partnerships and Objectives
Denis Aven will spin out from 8VC to lead this new strategy, focusing on three core objectives:
- Access to Talent: Nurturing a talent ecosystem to attract top operators who want to transition into entrepreneurship through acquisition.
- Tech-First Operation: Using technology to augment human capability and streamline operations, financing, and due diligence processes.
- Aligned Partnership: Ensuring that when operators win, Mainshares wins. This non-control structure supports independent ownership and long-term value creation for American entrepreneurs.
The authors emphasize the importance of this mission, stating it can help save tens of thousands of jobs while empowering new generations of entrepreneurs to build wealth and success in their communities.
