Project-based companies operate on a cash flow mindset, accepting any custom work that brings in immediate revenue. A true product company uses an investment mindset, strategically saying 'no' to short-term revenue to invest in building a scalable asset that can win a market long-term.

For established software companies with sluggish growth, the path forward is clear: find a way to become relevant in the age of AI. While they may not become the next Harvey, attaching to AI spend can boost growth from 15% to 25%, the difference between a viable public company and a sale to a private equity firm.

Mark Ein's investment model focuses on finding fantastic existing companies that have plateaued. He then applies a venture-style growth mindset to accelerate their trajectory, combining the stability of an established business with the rapid-scaling tactics of a startup.

Unlike SaaS startups focused on finding product-market fit (market risk), deep tech ventures tackle immense technical challenges. If they succeed, they enter massive, pre-existing trillion-dollar markets like energy or shipping where demand is virtually guaranteed, eliminating market risk entirely.

The true differentiator for top-tier companies isn't their ability to attract investors, but how efficiently they convert invested capital into high-margin, high-growth revenue. This 'capital efficiency' is the key metric Karmel Capital uses to identify elite performers among a universe of well-funded businesses.

Companies like Amazon (from books to cloud) and Intuitive Surgical (from one specific surgery to many) became massive winners by creating new markets, not just conquering existing ones. Investors should prioritize businesses with the innovative capacity to expand their TAM, as initial market sizes are often misleadingly small.

The era of generating returns through leverage and multiple expansion is over. Future success in PE will come from driving revenue growth, entering at lower multiples, and adding operational expertise, particularly in the fragmented middle market where these opportunities are more prevalent.

A core investment framework is to distinguish between 'pull' companies, where the market organically and virally demands the product, and 'push' companies that have to force their solution onto the market. The former indicates stronger product-market fit and a higher potential for efficient, scalable growth.

Recent acquisitions of slow-growth public SaaS companies are not just value grabs but turnaround plays. Acquirers believe these companies' distribution can be revitalized by injecting AI-native products, creating a path back to high growth and higher multiples.
