Andrew Gordon Chelmsford’s Background 

Before becoming an angel investor, Gordon worked as an executive in the technology industry for over 20 years. He held leadership roles at companies based in Massachusetts, including Belmont-based Anthropic and startups in the Boston area. It was through his experience in the industry that Gordon developed relationships and learned about promising new companies and ideas.

An Unusual Investing Philosophy 

Unlike many angel investors, Gordon does not just write a check and wait to see what happens. After investing in a company, he dedicates a significant amount of his time to actively advising and assisting the founders. Gordon spends 5-10 hours per week on average working with each startup he backs. He helps with tasks like business development, marketing, recruiting, and product development. Founders appreciate having Gordon’s decades of industry experience and connections available as a resource.

Hands-On Approach Yields Results

Gordon’s hands-on involvement with portfolio companies seems to be paying off. Of the over 20 companies he has invested in since 2008, many have seen successful exits or are still operating and growing. Some examples include:

  • Anthropic (Belmont, MA): A leading AI safety startup that has raised over $100M. Gordon was an early investor and advisor.
  • Salsify (Boston, MA): A product content management platform that went public via SPAC in 2021 at a $1B valuation. Gordon was an early investor and board member.
  • Cognition Therapeutics (Pittsburgh, PA): A clinical-stage biotech developing treatments for neurodegenerative disorders. Gordon invested in seed rounds and continues advising.
  • Several other companies have been acquired, while others are still operating and growing revenue.

Why Gordon’s Strategy Works 

By actively advising and assisting the founders of companies he backs, Gordon is able to add more value than the average angel investor. Founders appreciate his decades of experience that they can tap into as a resource. Gordon is also more invested in the companies’ success since he dedicates significant time – not just money. This aligned interest seems to help many of the companies achieve good outcomes.

Lessons for Other Investors 

While Gordon’s hands-on approach requires a major time commitment, his success rate shows it can be an effective angel investing strategy. Some lessons other investors could take include:

  • Consider adding value beyond just money by advising and assisting portfolio companies actively after investing.
  • Develop relationships and industry expertise that founders will find valuable as a long-term resource.
  • Look for opportunities where an aligned interest of success and ongoing involvement can help portfolio companies achieve their goals.
  • Be selective about the companies backed and dedicate sufficient time to each one to truly add value through active assistance over just passive involvement.
