2009
In 2009, Andreessen Horowitz made its two first investments: one in business management SaaS developer Apptio and the other in Skype stock.
The investment in Skype was seen as particularly risky by other experts, who believed the company would be crippled by ongoing intellectual property litigation and direct competitive attacks from Google and Apple.
The company's founders, however, viewed the investment as a success following Skype's sale to Microsoft in May 2011 for $8.5 billion.
This early success set the stage for the firm's future growth, as Andreessen and Horowitz continued to invest in multiple tech companies, eventually growing their investment from $300 million to $4 billion in just four short years.

Venture Capital Beyond Unicorns
The traditional venture capital partnership model is flawed, relying on a small group of founding partners' expertise and holding little lasting value once they retire.
Marc Andreessen, co-founder of a16z, aims to transition the firm into an enduring company by adopting practices seen in long-lasting financial institutions like J.P. Morgan and Blackstone.
This involves focusing on structured management, scalability, and long-term sustainability to ensure a16z continues to operate and support founders across multiple generations.
The VC partnership model can incentivize rapid growth at the expense of a company's long-term health and founder autonomy.
Critics of the model include unrealistic growth expectations, misaligned incentives between founders and investors, and a focus on short-term profits over long-term sustainability.
Vinod Khosla, founder of Khosla Ventures, believes that 90% of VCs do not bring value to startups and 70% even harm them by chasing short-term gains and quick exits.
By shifting focus to long-term company building and sustainable growth, VCs can support startups in achieving steady, manageable growth that aligns with their long-term vision.
