Kanter: Automotive aftermarket has a $200B repair and $40B upgrade market
“There's the kind of need-based repairs, which is, you know, somewhere as a Two hundred billion dollar market, so you know, your tire blows out, or you need a new muffler or something. And then there's the want-based purchases, which are the upgrades, and I was…”
Kanter: Launched first business by buying $2,500 of parts on credit
“So I signed up for a credit card, and I bought 2500 dollars worth of stuff, and I basically packaged it into a kit, each one of these different pieces, 12 different components or so, and I packaged it into a kit, and listed those for sale on the Impala SS foru…”
Kanter: Complex fitment criteria kept auto parts e-commerce penetration around 4%
“And because of the complicated fitment criteria, the e-commerce penetration rates in auto parts are very, very low. So I don't know the latest numbers, but when I was in the auto parts industry a number of years ago, the penetration rates in automotive were se…”
Kanter: Landing the first wholesale customer is much harder than consumer
“I learned that the hardest thing to do is to get your first customer in any one of these segments. It's okay. Like consumer is, is, it's not that hard to get your first customer. There's enough people out there. In terms of wholesale, everybody wants to know, …”
Kanter: Venture capital makes far more sense for high achievers than bootstrapping
“So as a high agency person, being able to remove the fundamental constraint of capital as the limiting factor of a business, like, to me, it's like the equivalent of going pro. I think that there's vastly more cases in which venture capital makes sense for a h…”
Kanter: Founder anti-VC bias stems from confusing ownership with control
“Would you rather own, you know, a hundred percent of a ten million dollar business or 10% of a billion dollar business? Like, of course, I think unless you really have some obsession with ownership, but I think most of these things are confusion about ownershi…”
Kanter: Founders who hate their companies only have themselves to blame

Kanter: Stedi shares good news only after it happens, bad news immediately
“To start with, I'm only going to tell investors good news after it happens and bad news Either hopefully before it happens or as soon as it happens, worst case.”
Kanter: Half of B2B deals that seem 99% likely to close fail
“Of B to B deals that seem 99% likely to close, 50% of them fall through.”
Kanter: Listing pending POCs to investors has almost pure downside
“I think there's just almost pure downside in listing these things out to investors.”
Kanter: Value Is Built in the 'Muck in the Middle', Not the Start or Exit
“Yes, the beginning of something can be exciting, and the end of something can be relieving, but like, by and large, the muck in the middle is where the value is built.”
Kanter: Tremendous alpha comes from simply executing fundamentals better than competitors
“There's a tremendous alpha that can be found from doing things better than other people.”
Kanter: Auto parts startup's final EBITDA margin was 2.5x investor projections
“When I sold the business, I went back and I looked at those projections that I had sent them. And the actual EBITDA margin that I achieved, the actual real profit, not just a fake EBITDA margin, was two and a half times what I had shown to them at that time.”
Kanter: The entire physical supply chain ecosystem runs on legacy EDI standards
“And so you fast forward to today and the whole world of retail logistics, transportation, supply chain, manufacturing, and revolving around physical products works off of EDI.”
Stedi threw away its entire codebase roughly eight times before public launch
“It took four and a half years for us to launch anything publicly. And what you don't see during that time was that we threw away everything that we had built completely, every line of code, maybe eight times.”
Kanter: Legacy EDI companies became trapped by accepting interim technical compromises
“And I think that you gain more of an appreciation for how the other EDI businesses ended up where they are, because they got to one of those paths and they said, all right, like this is gonna, this gets us kind of part of the way there and we'll fix it later. …”
Kanter: Software systems ossify after two to three years of shipping
“What you generally see is that companies are able to ship for some short period of time, two years, three years, and then the system ossifies and then they go and they're kind of stuck with that system. Going forward, and that's basically what they're gonna se…”
Kanter: Rippling is a rare counterexample to software ossification
“Counter examples to that, of course, you know, Rippling would be one great counter example to that as this, you know, this compound product that's shipping, you know, lots and lots of features over, over a long period of time.”
Kanter: The best entrepreneurs are risk killers who trim failure paths
“There's a myth that the best entrepreneurs are risk takers. When in reality, the best entrepreneurs are risk killers and they're trimming away failure paths. And Thing is when you trim away a failure path, your odds of success go up.”
Kanter: Healthcare clearinghouses enable single-connection integrations unlike retail EDI
“So no matter how big you get as an EDI company, you have to integrate every single one of your vendors one by one with Walmart or Tractor Supply or Target. There isn't this such thing as you connect once and the transactions just start flowing. In healthcare, …”
Kanter: Change Healthcare was down 60 days after cyberattack
“Change Healthcare, which was the largest clearinghouse for claims. They got hit by cyber attack and they were down for 60 days. You know, and even today, they're not fully back up. There's the dental portion of their business is not back up. There's a bunch of…”
Kanter: True product-market fit is when customers buy despite missing features
“It's when people are buying the product despite all the things that it doesn't do. And the deals are closing anyways. The deals are closing anyways, and everybody's so happy.”
Kanter: Execution is definitely not a moat in software
“Very common thing people say in software in, in, in venture. Oh, the only execution, the only mode is execution, which is not, which is definitely not a mode.”
Kanter: Most buyers won't pay more for software beyond 80% quality
“The reality is that most people don't care about the product only being 80% as good. For most people that doesn't matter. They're not willing to pay a lot more for that incremental, incremental piece.”
Kanter: Moats require sustained lower costs or pricing power
“If something doesn't lead to Lower costs, sustained lower costs over time, or the sustained ability to charge higher prices over time, and ideally both, it is not a moat.”
Kanter: Stedi de-scopes features until they are barely usable by one customer
“If the, if there is the option to ship things
Incrementally.
It is, I think, virtually always better.
And that's how we ship things now.
Like we ship, we don't ship big bang features.
In fact, like we de-scope features to the point of where we're, where we thi…”
Kanter: Engineering leaders should prune design docs to maximum two miracles
“All software is a cascade of miracles.
Like when you look at something, you know, I think you go and vibe code for a weekend and you're like,
oh my God, you know, why doesn't my company ship more?
Because I just shipped all the, look at all the stuff I shipped…”
Kanter: Software founders have more to learn from discount retail than other industries
“I think that there's more to learn from the category of discount retailing than there is, you know, in software than there is to almost any other category.”
Kanter: Product-market fit only fixes operational errors if gross margins are high
“I think that product market fit is the antidote to stupidity provided that is product market fit with high gross margins. And I think like product market fit with low gross margins is, is a tough business.”
Kanter: Healthcare transactions cost orders of magnitude more than SMS or AWS
“When you compare the price of a, Claim or an eligibility check to a text message or to a transportation status message or to an S three read or write or storage or something like that. It's orders of magnitude more expensive.”
Kanter: Focusing on quality reduces costs more reliably than cost-cutting
“Always focus, focus on improving quality because the quality gains usually materialize. If you say like, okay, we're going to reduce the defect rate or we're going to, it's just like a very measurable thing. And, but what you find is that by improving the qual…”
Kanter: The quality-price-speed trade-off is an illusion
“They say, okay, well, you know, quality, price, and speed, you have to pick two. And I think that that is like the most losing mindset in business and engineering and design and whatever the thing is. And that the trade-offs between those three are usually an …”
Kanter: Stedi tells new hires on day one that everything is their fault
“On everybody's first day at Steady, I say, welcome to Steady, everything's your fault now. And then I say it's not as bad as it sounds, actually, everything's your fault now also. You know, everything's your fault, and your manager's fault, and everything kind…”
Kanter: Stedi screens for candidates held back by their current environment
“What we think about during interviews is what I look for during interviews. I want to get a sense that the person is held back by the environment that they're in, that this person could be achieving more if not for the team that they're on or the organization …”
Kanter: 20 years of experience is often just one year repeated 20 times
“In the beginning, you look for people who have a lot of experience. And then you realize you hire someone with 20 years of experience, and they don't have 20 years of experience, they have one year of experience repeated 20 times. By contrast, you hire somebod…”
Kanter: When hires fail, it is almost always for anticipated reasons
“People are very loudly and obviously going to broadcast to you who they are and what they believe in and what they want and what they want to do and how they're going to act. And it's up to you to listen to it. And like the reasons why someone doesn't end up w…”
Kanter: Stedi gives identical support to $500/month and seven-figure clients
“We don't have a different support program, any internal designation for support between customers who pay us seven figures per year and customers who pay us 500 dollars a month. This is the exact same support.”
Kanter: B2B companies rarely suffer from edge cases warned against
“You find that most of the things that people warn you about don't come to pass. And like most of these edge cases don't come to pass. I think it's a little bit different in consumer with fraud and stuff like that, but it'd be to be generally don't need to worr…”
Kanter: Internal consistency matters more than following standard playbooks
“When things are working, it kind of, not that it doesn't matter what you do, but there's lots of different ways to be successful. The important thing is that the decisions that you're making are consistent and that they're well implemented. So some of this stu…”
Kanter: Demo Days Exist for Shared Context, Not Productivity Tracking
“We do demo day because it's a way that everybody can get a shared understanding of how the product works and what's changing. And also because it encourages people to ship in incremental units that are viewable on a week by week basis. It's not the purpose of …”
Kanter: As CEO, I review every pull request across the organization daily
“The other thing I do is I look at, you know, take at least a cursory look at all the pull requests that are made throughout the organization every day.”
Kanter: Principles are unconditional commitments, while preferences depend on trade-offs
“I think that when you think about, you know, basic way I describe principles versus preferences, it's like a principle is something that you're doing no matter what, you know, that, that you would, that you are dogmatic about it. And the preference is somethin…”
Kanter: Amazon Transcends Bezos While SpaceX Heavily Relies on Elon Musk
“If Bezos were no longer CEO of Amazon, you know, the businesses, I think the business would suffer, but I don't think that the business, like, if Elon were no longer the CEO of SpaceX, I think that would be a huge problem. Amazon is in really tough spaces, tou…”
