Sherman: Angel investors refused a refund 30 days into Spotfronts

Sherman: SMB MarTech unit economics make no sense
“I wouldn't wish like SMB MarTech on my worst enemies. The unit economics make no sense. It is, it's just a really, really tough, tough space and props to companies like HubSpot that, you know, like figured it out.”
Sherman: JPMorgan Chase was the first customer for his ad tech startup
“Our first customer was JP Morgan Chase. They had their Chase Inc. Credit card that was marketed to SMBs.”

Alex Sherman: Enterprise PMF feels like a river current reversing direction
“It's like the current of a river reversing direction.
Capitalization.
One day you're sort of going against the current and all of a sudden the next day the current switches and everything is that much easier.
So you feel it, unless you're not paying attention,…”
Sherman: PromoteIQ scaled fundraising from $2M to $10M-$15M after hitting PMF
“I think we went from having raised like two million dollars to raising like somewhere between 10 and 15. So we took that first big kind of slug of capital.”
Sherman: Founders must assume competitors see the exact same PMF inflection points
“Anytime you have a sort of inflection point in the business or you discover something or you feel like you have real fit, My second thought is paranoia. My second thought is like, okay, there is some other team somewhere that is learning the same thing or that…”
Sherman: Ad tech was completely out of favor in 2016-2017
“There could not possibly have been a less sexy category than ad tech in 2016, 20 17. Forget it. No one was touching that.”
Sherman: Microsoft had a $10B ad business when acquiring PromoteIQ
“It was a ten billion dollar ad business, something like that. You know, they saw retail media as kind of a really strategic expansion opportunity. And so that was what led to our acquisition.”
Sherman: Startup M&A decisions are like taking exits off a highway
“There's this metaphor of like exits off the highway that a lot of founders use. And when you get an exit off of the highway, if you say no, then you need to know like the next exit is 50 miles away or a hundred miles away. And I think M&A for founders is Is ab…”
Sherman had $2,000 in his account before Microsoft acquired PromoteIQ
“I still remember I had 2000 dollars in my checking account. And so I was like looking at my Wells Fargo app and it was like, 2010 dollars like that.”
Sherman: Second-time founders overrate early ideas due to prior knowledge
“And as like second time founders, you know more. And so you sort of believe that these ideas are better.”
Sherman: A new marketing channel emerges every 5 to 10 years
“Every five to 10 years, you get a new marketing channel that emerges and it plays out the same way every single time. You get new technology that changes how consumers use the internet, right? Like the rise of search, the rise of social, the rise of mobile.”
Sherman: Enterprise marketing stacks will need rebuilding for AI channels
“This is where the market's going over the next five to 10 years. Your marketing stack is going to need to be rebuilt for this new AI channel.”
Sherman: Bluefish raised its first round on just an idea and deck
“In our earliest days as Bluefish, we raised our first round without a business. It was an idea and a pitch deck.”
Sherman: Second-time founders must be discerning because venture capital is not
“I think that is another trap is that as second time founders, there is no shortage of capital that is chasing you. And if you're not discerning, the capital won't be.”
Sherman: Many founders cannot replicate their startup success a second time
“Realistically, there are a lot of people, and this includes founders that can do it once and they can't do it again because it's just fucking hard.”
Sherman: Brands' first need in any new marketing channel is visibility
“Anytime there's a new channel, there's kind of this like hierarchy of needs that a brand has. And this applies to social. It applies to mobile. It applies to search. It applies to every time there's been one of these new channels. The first thing you need is v…”
Sherman: AI platforms like ChatGPT will inevitably introduce pay-to-play ads
“As soon as your brand and you recognize that their transaction has moved into the AI funnel and that a consumer can go to ChatGPT and say, Hey, I'm training for a marathon and 10 minutes later can buy a pair of sneakers within that same conversation on ChatGPT…”
Sherman: Bluefish clients spend $1B to $5B annually on marketing
“Our customers individually spend anywhere from one to five billion dollars a year on marketing across, you know, organic and paid and analytics and data infrastructure, the whole marketing stack.”
Sherman: Product-market fit must be rebuilt for each new industry chapter
“I think of industries and like deployment cycles as having different chapters and your product market fit might be fine for one chapter, but you have to rebuild it for the next and the one after that.”
Sherman: Always fly out to meet enterprise customers in person
“My number one piece of advice is just get on the plane. Always get on the plane, go meet with your customers. It never makes sense. No one wants to get on the plane. It's always like, well, this is an informational meeting. Why do I need to be there in person?…”
