The record, in short

Their most notable supported claim
Song: Older Social Security numbers are predictable by birth year and location
“Back in the day, like, social security numbers weren't random. In fact, like, if you're born, like, I think prior to 1991 or something, your social security number is a company. The first five Is identified by the location of where, which hospital you were bor…”
Everything Rick Song said on A Product Market Fit Show that made the record, most notable first. Filter by type, assessment or year in the ledger →
Song: Persona paused vertical outreach after closing one customer per industry
“Once we close one customer of a certain industry, no more customers of that use case or industry. Like we're not even like going to talk to anymore unless it was in balance.”
Song: Hiring technical team members without prior working history multiplies failure risk
“If you're just out trying to hire, like, some random engineer or technical person that you have zero experience with or otherwise I've seen some of the statistics around this. Your probability of, like, failure is, like, not just, like, two x higher. It's, lik…”
Song: Fast growth to $1M ARR indicates an easily replicable product
“The faster that your product can get to a million, the faster your product is likely easily replicatable.”
Song: Decision velocity matters more than decision quality for early startups
“It's actually unlikely thinking a long time about decision will actually dramatically improve outcomes. Especially for like very difficult, you know, like uncertain decisions, actually like making a decision and then quickly reverting or like just learning fro…”
Song: Persona's success was 80% luck and 20% input
“I would say it's 80% luck, 20%, you know input, right? Like, it's so much luck that just went right, and it's not just luck from, like, a, oh, we stumbled on the right idea, the right timing. People who, like, ended up just in the right situations at the right…”
Song: Refactoring is driven by product requirements, not tech debt
“And I actually think refactoring fundamentally is a product-driven question, not just a, like, tech debt-type question, right? I think, like, this quote-unquote, like, tech debt thing sometimes is overly how do I put it? It's I think, like, overly abstract of …”
Song: Many founders self-delude rather than trying to disprove their ideas
“I think a lot of founders have a tendency to self delude into believing like, oh, as long as they just like keep on, you know doing it, it'll work out. But while they think that they also aren't actively trying to prove that it's going to fail, like, you know,…”
Song: Persona actively anti-sold candidates until reaching 100 employees
“No, I mean, I think this went on again, like even up until we were like a hundred people, I was like, look, like if you're joining us, it's probably a waste of your time and a terrible choice in your career, but you may like it, right?”
Song: There is no silver bullet for identity fraud
“A lot of these vendors would promise you some sort of silver bullet saying like, this is the, you know, one silver bullet to solve all your identity problems, fraud would disappear, you know, very, very extreme claims. But the reality for us as a business and …”
Song: Face ID confirms same-user access, not government-recognized identity
“Face ID may be able to tell you that it's the same person, but again, our challenge is not about, is it the same person? The fundamental question we have is who are you within like some sort of registry? Who are you as recognized by the government?”
Song: Online identity verification friction has increased over the past five years
“Even from the start of persona over the past five years, the amount of friction, the amount of effort to do that has not only has not decreased. It's actually only increased. Like we're watching the complication of how to be ourselves online get progressively …”
Song: Founder psychology is harder than finding first customers in zero-to-one
“I think actually the hardest stage, like if you're talking from like the zero to one phase, the hardest stage is not so much like, you know, something external, like finding a first customer's all of that. I actually think the heart, like, the biggest enemy yo…”
Song: Persona rewrote its codebase after almost every early customer
“Almost after every single first of, like, our first 10 customers, we would almost rewrite things from the ground up to make sure that, like, it didn't feel overly specific for that one use case.”
Song: Persona still lacks product-market fit despite hitting $100M ARR
“I mean, a common question I actually get a lot is like, have we found product market fit or when did you feel as if you found product market fit? And I'll be honest with you, I still don't feel it.”
Song: Product-market fit only felt distinctly different when Persona reached 50 customers
“There's definitely a bit of that, but I will say, like, the only point I really felt, like, as a truly major jump on the product market fit questions, when I got one customer at 50, like, that actually felt, like, meaningfully different. After that, I wouldn't…”
Song: A long tenure at Square was Persona's biggest success factor
“If there were one thing I credit to, the best thing that made personas, like, increase the persona success, it was how long I was at Square. And I'd like to say, you know, I was dedicated and like did a fairly decent job, but I think like above all else that a…”
Song: Persona refused investment capital from friends and family
“I think we had a rule that we did not take any funds from any friends or family, because we just didn't want that additional pressure of any way, shape, or form.”
Song: Persona has never pivoted since its founding before its MVP
“Literally from day one, we've never really pivoted. We've never, like, our long-term vision was, like, almost crystallized even before our MVP.”
Song: Older Social Security numbers are predictable by birth year and location
“Back in the day, like, social security numbers weren't random. In fact, like, if you're born, like, I think prior to 1991 or something, your social security number is a company. The first five Is identified by the location of where, which hospital you were bor…”
Persona's first customer paid roughly $50 a year for age verification
“It was an e-commerce site. Actually it was a friend's friend of a friend's e-commerce site and they needed to do you know, like age verification. The only thing we were willing to really focus on was we will do anything around identity. It wasn't even like our…”
