The Follow-On Signal


The most persuasive thing in a fundraising room is not a slide. It is an investor who already knows the company and chose to put in more. PitchBook–NVCA’s Q3 Venture Monitor says U.S. venture deal value reached a record $515.8 billion through September — but AI took 82.7% of it, funds of $500 million or more captured 78.1% of fundraising, and just 18 companies went public in Q3.

Two rounds from the last two days show what breaks through that concentration. Seva Money raised a $5 million seed with all three of its pre-seed investors coming back in. Light Frame raised an oversubscribed $5.1 million seed with its existing investors returning. Neither group re-upped because of a deck — they re-upped because they had watched the company and liked what they saw.

The lesson: the follow-on is earned between rounds, and it is earned with measured results. As I wrote in The Impact Factor: “Measuring over time paints a picture of your impact.” And: “Setting a goal or intention is NOT what provides the power to cause the desired outcome.”

About Ken McArthur

Ken McArthur is the founder of ConnectLab.live, an AI relationship-intelligence and warm-intro platform that helps founders who are raising find the funds that fit and the people who can introduce them, and helps fund managers connect with the founders they back. He was recently accepted into Harvard Business School Foundry. He also writes Raise Smarter, a daily newsletter on what's really moving in early-stage fundraising. Ken challenges us to realize we ALL have an impact, whether we want to or not, on thousands of people we touch in our day-to-day lives, and he shows that simple things make a HUGE difference. ConnectLab.live grew out of that belief. Connection is the currency of the 21st Century, and the right introduction can change a company's future. Long before ConnectLab, Ken was the popular host of live events that brought together top-level marketers, entrepreneurs, business owners, corporations and non-profit organizations to build multi-million dollar joint venture relationships. He has managed product launches ranked in the top 400 sites on the Internet and is regularly asked to speak at leading marketing events. He created AffiliateShowcase.com, a pioneering affiliate program search engine and directory. He also founded the MBS Internet Research Center, which conducted the world's largest survey ever attempted on creating and launching successful information products. Ken was the official mentor for Sterling Valentine as he took his launch from zero to over $100,000 in less than 8 days, a proof of concept documented in Info Product Blueprint. Today he puts that same skill for connecting people and launching ideas to work for founders and the investors who back them.
