|---|---|---|---|---|---|---|
| Bill Magnuson's Formative Experiences at Google and Bridgewater | 3 | 5 | 1 | 1 | Brett asks targeted exploratory questions about Bill's path through MIT, Google, and Bridgewater. Bill explains how Bridgewater's extreme operational transparency and systems thinking prepared him for company scaling challenges. | |
| First Principles in Practice: Early Data Privacy Conviction | 4 | 6 | 2 | 2 | Brett pushes for a concrete instantiation of the overused 'first principles' buzzword.

| The TechCrunch Hackathon and the Inception of Appboy | 3 | 4 | 1 | 1 | Brett prompts Bill on the founding mechanics and hackathon project. Bill shares the story of winning the TechCrunch Disrupt Hackathon, meeting Mark and Bipul Sinha, and conceptualizing Appboy over a single dinner. | |
| Architecting a Real-Time, Cross-Channel Engagement Platform | 4 | 5 | 1 | 1 | Brett probes how early whiteboard sessions led to a multi-channel architecture rather than a single-point solution. Bill and Kevin describe why they rejected single-channel push tools in favor of building cross-channel infrastructure from day one. | |
| Kevin Wang Joins Appboy as Employee Number Eight | 3 | 4 | 1 | 1 | Brett inquires into Kevin's recruitment and background. Kevin and Bill recount the scrappy early days in a sweltering WeWork office and how Kevin's neuroscience and technical background complemented the team. | |
| Early Market Skepticism and the Bet on the App Economy | 4 | 6 | 3 | 1 | Bill and Kevin explain why they deliberately ignored early customer feedback that suggested mobile apps were ephemeral hobbyist products.

| Pioneering Real-Time Event Streaming over Batch Processing | 4 | 7 | 2 | 1 | Bill and Kevin educate Brett on the architectural difference between real-time event streaming and legacy SQL batch processing. Marketers accustomed to overnight batches did not initially grasp instant stream classifiers. | |
| Customer Discovery, Growth Teams, and Enterprise Traction | 4 | 6 | 2 | 1 | Brett asks how Appboy landed its earliest paying customers. Bill and Kevin describe discovering emerging growth teams, avoiding the short-term gaming whale trap, and deliberately rejecting lean startup advice to build a broader product. | |
| Pivoting the Business Model and Scaling Globally | 4 | 6 | 1 | 1 | Brett asks about early monetization pivots and global expansion. Bill outlines moving from an ad-network monetization model to enterprise SaaS contracts, noting that 45% of revenue was international from the start. | |
| Navigating Dynamic Product Market Fit and Competitive Noise | 5 | 6 | 2 | 2 | Brett pushes the guests on whether PMF is an uphill climb or downhill acceleration, and asks them to distinguish skill from luck. Kevin explains that PMF is dynamic and requires continuous shots on goal across new adjacencies. | |
| Tactical Founder Advice: Long-Term Conviction and Product Velocity | 3 | 6 | 2 | 1 | Brett asks what core advice they give to prospective founders. Bill emphasizes long-term decade-scale conviction and capital strategy, while Kevin highlights the inevitability of product velocity foot races. | |
| Competitive Strategy, Product Jujitsu, and Leadership Lessons | 5 | 5 | 2 | 1 | Kevin rejects common startup advice to ignore competitors, advocating situational awareness and product jujitsu. Brett synthesizes this insight by noting the value of picking the right customer rather than bending product architecture. |
Statements from this episode (18)
Magnuson: Early App Store pricing models held back mobile software businesses
“Paradoxically, even the purchasing of mobile apps in the app store, I think in the early days was holding back people thinking about building those businesses because you didn't have any recurring revenue or ongoing revenue streams from your mobile app users. …”
Magnuson: Braze never rolled back features due to privacy or OS changes
“I feel confident saying, I don't think we've ever had to roll back a feature we've built over time because of new data privacy legislation. Legislation or new changes in the operating systems.”
Magnuson: Braze launched as a cross-channel platform, avoiding single-channel silos
“Unlike a lot of companies that are built to just be, oh, we're going to be a push notification service, or we're going to do email marketing. Like they all start on a single channel. We were just trying to solve a business problem. And so we knew that we neede…”
Magnuson: WeWork ran out of money building its Meatpacking location
“It was down in the meatpacking district. It was the early days of WeWork and they actually ran out of money while they were building it.”
Wang: Early startup peers were way smarter than big consulting colleagues
“This is very, very different from big consulting, I would say. The people are way smarter, and this is a very much more scrappy environment.”
Magnuson: Braze targeted developers early on because mobile apps lacked marketing teams
“Interestingly, didn't start out building for marketers, which is interesting, but it's just primarily because mobile apps didn't have marketing teams when we first started the company. You know, if you don't have a business model, there's not a lot of reason t…”
Magnuson: Early app makers rejected Braze because engagement raised server costs
“And even when we went and talked to some of our potential early customers, I remember someone telling me that they didn't want our service because the sooner people stopped using their app, the sooner they could stop paying the server bill for those people. An…”
Magnuson: Braze removed user feedback module after sales cycle distractions
“We actually removed the user feedback module entirely. You know, first we experimented with stopping demoing it because it ended up being a distraction during sales cycles. And we felt that the space we were working in around specifically in fully automated en…”
Wang: AI in 2025 is earlier in evolution than early-2010s mobile
“I think there's some interesting parallels, say, to where like AI is today, where I think that AI is probably a few quarters earlier than that, and people still don't know what's, what's going to happen, and there's a lot more change going on, so it's probably…”
Magnuson: Mobile apps freeze risk force-quits if latency exceeds 50 milliseconds
“And if it freezes for more than 50 milliseconds, you think that it's died and you're going to force quit it, right? Like you had to be interactive in terms of the personalization of the delivery.”
Magnuson: Early GTM must target customers willing to overlook missing table-stakes features
“We needed to make sure that our go to market was targeted at the people that appreciated our differentiators enough that they were willing to ignore the things that we were missing that were table stakes.”
Magnuson: Braze never received multiple term sheets until its Series D
“It wasn't until our series D six years into the business that we ever had a fundraising round where we got more than one term sheet.”
Magnuson: 85% to 90% of mobile SaaS in 2012-2015 targeted gaming
“If you go back to 2012 to 2015, probably 85, 90% of the SaaS businesses that were in mobile were very focused on helping the gaming industry because it was the kind of quickest route to make money in the early days.”
Magnuson: Competitors burned out raising $50M Series As in an immature market
“We actually had a number of competitors in the early days who went out You know, at the same time we went and raised 10 to fifteen million dollar Series A, they went and raised a fifty million dollar Series A, and they actually burned themselves out. Despite h…”
Wang: Marketing creates power-law outcomes and intense competitive selection
“These marketing buyers did have, there are a lot of network effects of marketing, because if I'm running much better marketing than you are, and we have a very similar sort of brand, I'm going to win and I'm going to win really big. I'm going to win sort of li…”
Magnuson: Only one of Braze's first 10 major customers was in NY
“Cause our first. 10 very large customers. Like one of them was in Berlin. One was in Norway. One was in Armenia. We had one in Singapore, you know, and then there were another half a dozen that were in the U S I think only one of them was in New York.”
Magnuson: Raising venture capital forces founders into relentless hyper-scaling
“There's a lot of businesses that people may start that are not appropriate to be venture backed. And when they go and they try to kind of back them with other investors, they very quickly lose control of exactly what trajectory it needs to be on and, you know,…”
Wang: Thinking about competition under $5M ARR is generally distracting
“And even I would say up through maybe two million to five million ARR, I think that thinking too much about competition is generally distracting for two reasons. One is that you don't really know the identity of your company and also you don't know You are not…”
