Advanced AI has changed how startup funding works. Raising large amounts of money used to be a risk, but now it gives AI companies a growing advantage.

David George and Jen Kha of A16z (Andreessen Horowitz), alongside Aram Verdiyan of Accolade Partners, explain how computing power builds a strong defense. They also discuss how AI tools are taking over human tasks, why older software companies must adapt, and the strict rules investors must follow to survive.

AI compute turns capital into a compounding moat

While traditional rules punished excessive funding, AI infrastructure rewards massive capital by improving models and strengthening a company’s technical advantage.

David George notes that throwing dollars at compute compounds a company’s advantage, establishing benefits for startups:

• Snowballing momentum: Compute spending improves AI models and allows companies to meet customer demand.
• Market domination: The cost of doing business pushes out competitors who lack technical resources.
• Redefined warning signs: A massive investment proves a business has the technical capability to dominate the market.

Generative tools devour human resource budgets

The advantages gained from compute spending allow these models to replace human labor and access corporate budgets.

Aram Verdiyan notes that AI reached “US$100 billion in revenue” in four years, compared to 15 years for software. This growth is accelerating automation across sectors, including:

• Healthcare administration tasks facing automation.
• Legal work reliant on human billing hours.
• Customer service divisions burdened with labor costs.
• Coding and software development workflows.

Software companies now struggle to maintain valuations as buyers demand proof of growth. Selling these businesses to investors is impossible when a leadership team lacks AI expertise.

Market concentration requires investor discipline

Because only a few winners will capture these labor budgets, boards and investors must adopt rules to survive this concentration:

• Demand workflow integration: Kha warns that rushing to automate damages the user experience, noting that “just because you put Sears on a website doesn’t make it Amazon.”
• Abandon legacy products: Companies like Intercom rebuilt their platforms around AI technology to retain users.
• Prioritize deal access: Portfolios require managers who secure investments with market leaders before financial data becomes obvious.
• Make large bets: Investment amounts need to be large enough that a single success boosts the fund.

Verdiyan notes that since only a small fraction of firms perform well, investors “should concentrate in those 15 or 20 firms pretty consistently.”
