In this episode of The Sunny Ray Show, host Sunny Ray talks with John Frankel, founding partner at FF Venture Capital and a technology investor for more than 25 years. The conversation opens with a deep dive into declining global fertility rates, with Frankel, a father of six, arguing that people drift through life without a long term plan and end up having fewer children than they might have wanted. He connects this to broader ideas about wealth, gratitude, and societal envy toward billionaires. The discussion then shifts to Frankel's path from studying mathematics, philosophy, and logic at Oxford, through 21 years at Goldman Sachs in prime brokerage and equity research, to becoming an early angel investor during the 1999 dot-com boom. He shares stories from Goldman's early internet skepticism, explains why accounting discipline is an underrated edge in venture investing, and reflects on what it actually takes to know whether a VC is good at the job. The episode blends personal philosophy, career history, and hard won startup investing lessons.
A Goldman veteran turned VC on fertility, wealth, Oxford logic, and why accounting discipline wins in venture investing.
What's got you thinking about kids and declining fertility?
I got married young, had a bunch of kids, and now have over 15 grandkids. At a societal level fertility is dropping everywhere, well below the 2.1 replacement rate. I think people just drift through life instead of planning, and by the time they settle down and get married they've lost fertility or capacity to have more than one or two kids. If that's genuinely what someone wants, fine, but most people never actually decide.
How many children do you have?
We have six, five biological and one we kind of adopted who's a wonderful girl.
You studied mathematics, philosophy, and logic at New College, Oxford. What were you chasing back then?
I was a naive 17 year old. I could do math but didn't enjoy it, and I couldn't string two sentences together, so I figured math would be my fallback and philosophy would teach me to write and think in a structured way. A third of my degree ended up being logic because Michael Dummett, the Wykeham Professor of Logic, was at my college.
How does that math, philosophy, and logic training show up today when you sit across from a founder?
It compounds with everything after it. Accounting training from Arthur Andersen gave me the numbers side, and 21 years at Goldman, including as an equity research salesperson covering hedge funds, forced me to understand dozens of industries and business models and communicate ideas fast. Philosophy shaped how I express ideas. Now when I sit with a founder I have a rich mental library of business models to place them against.
You were building technology inside Goldman Sachs before anyone used the word fintech. What did you see coming that the outside world missed?
In prime brokerage in the mid-90s I proposed running our reconciliation application on our own servers instead of on hedge funds' desktop PCs, with clients accessing it through Mosaic. The chief technology strategist told me the internet was just a plaything for me and that we dealt with real business. There was zero institutional expectation the internet would matter, which gave me an early read on where things were heading.
Late 1999, still at Goldman, you start writing angel checks in the middle of dot-com mania. What pulled you in and what was the first deal?
The first deal was Theatermania, a ticketing technology company that exited 23 years later at about a 3% IRR. Back then roughly a quarter of the firm was focused on tech and telecom and a lot of colleagues were leaving for startups, so my Rolodex shifted from Wall Street to the startup community, and that natural exposure led to opportunities, some of which turned out very well.
Your contrarian belief as an investor is that accounting matters. Can you unpack that?
GAAP accounting alone doesn't tell you if you can make payroll, since accrued expenses aren't cash. You need cash accounting and, with multiple products, product line contribution margin cash accounting to know whether you can actually fund growth with what you have. Negative working capital businesses can look great while growing fast and then run out of cash the moment growth slows. Most investors miss this.
