BIG NEWS: We just launched CheckThat[.]ai Buyer Intent + Free AEO Platform + Shared Prompt Library No cold start. Historical data included. --- "Seriously!? Yet another AEO tool?" I get it. I felt the same way. But I'm convinced the AEO category is fundamentally broken. Not the tools themselves. The assumption behind ALL of them: That tracking = improving. It DOES NOT. Google Analytics doesn't grow your traffic. An AEO subscription doesn't grow your AI visibility. What actually happens: Sign up → bad context → random prompts → zero data → $500-$3K/mo invoice. For prompts you're not even confident in. --- We took the complete OPPOSITE approach with CheckThat: We did the heavy lifting before you show up: → Top B2B software categories mapped → 5,800+ brands researched (and growing) → Millions of AI responses tracked daily → Human-reviewed prompt library (shared + free) Why? Working with 100+ brands at @GrowthXAI taught us: CONTEXT is everything. Your context drives your content quality. Your content quality drives your AI visibility. You can't create great content without context. You can't get context without understanding your buyers. You can't understand your buyers without data. --- To celebrate the launch, I'm doing 50 Free AEO Audit + Strategy sessions over the next month Retweet this post & comment "checkthat" and I'll send you a DM to get scheduled.

Today is my birthday, and I keep thinking about a school cafeteria table. I was 11 when we moved from Brazil. I didn’t speak English. I was a stranger in what felt like a completely different universe. School became a daily exercise in trying not to be laughed at. Trying to blend in. Trying to get through lunch. I can still see the cafeteria. It seemed like everyone had a table. Everyone knew where to go. I didn’t. I think some part of me has been standing in that room ever since, looking for a place to belong. For a long time, my answer was to work harder. Outsmart everyone who wouldn’t let me in. I watched people closely. I learned to spot patterns, think ahead, figure out how to get their attention. Those skills have helped me build a life. They also came from a kid who was scared. Then I learned graphic and web design. I could sit for hours making things, like I used to with Lego. I built a website and figured out how to get customers online. The first time a real business filled out my form and paid me for work, I was blown away. I was a teenager. They had no idea. I’d made something and someone found it. For once, I didn’t have to wait for someone to pick me. I can see that thread through so much of my life now. Building things people might care about. Giving away value. Hoping the right people would find their way to me. MY PEOPLE. I wanted more than customers. I wanted a team I loved being around. I wanted to make a place where we could do work we believed in and where other people felt they belonged too. My team and I are building that table at @GrowthXAI. We help companies figure out what they stand for, make something valuable, and find the people they’re here to serve. I think of a website as their TABLE: a place to show up as themselves and invite those people in. And honestly, the fear hasn’t gone away. I still wonder if I’m faking it. If I’ll fail and everyone will see. I know where that voice came from. I’m trying to hear it without letting it run my life. … Today, I just want to express my gratitu to the people around me. Those that have joined my table in some way. At the team building this with me. At everyone who made room for me along the way. Thank you. It means the world to me. Much love ❤️

Survey is live. 27 questions on AI adoption, budget, content ops, and AI visibility. Not asking if you use AI -- asking how your strategy has actually changed. Link in comments.

yea.. AI agents can build anything now building isn’t impressive anymore context and data decide who actually gets visibility

Just dropped on @lennysan’s podcast. We bootstrapped @HelloSurgeAI to >$1B revenue with <100 people by obsessing over one thing: data quality matters more than everything else. Lenny and I talked about: • Why Anthropic and Google are winning • The brutal choice model builders face: Engagement vs. Values • The underappreciated post-training skills: Taste and Sophistication • Why Fields Medalists love teaching models on our platform • What RL environments teach us about agents • Why we're still a decade from AGI Listen to it here: lennysnewsletter.com/p/surge…

great time w/ @saranormous @eladgil about the perils of benchmarks, SV startup monoculture, why you'll throw out 95% of your synthetic data (6 mo after the mess it made), RL richness, and why frontier math is a lot like poetry.
New 🔥 episode drop! Edwin Chen, CEO of Surge AI, is one of the best placed to understand the model landscape and evolution of data needs in AI. His hot takes: differentiation, Scale/Meta, why human data will prevail, why LMArena is “trash” and why founders need to stop hiring.

my first ever podcast! great time jamming with @HarryStebbings @20vcFund about @HelloSurgeAI, why the best researchers don't sacrifice data quality for anything, and why startups should focus on building the best product instead of hype machines
$1BN+ in revenue. $0 in funding. “I would not sell to Zuck for $100BN.” Surge AI. The best company in tech that you might not have heard of. Their Founder, Edwin, never does interviews. Today he shares all with 20VC and my top 7 takeaways 👇

Context: I was @scale_AI marketing leader for 2 yrs. @HelloSurgeAI is truly the antidote to all the Scale AI type human body shops out there. Claude and best frontier models out there are that much better bc of human expert data, not bounding boxes. More founders should aspire to be like @echen: - First principles building - Quiet confidence - Focusing on the right primitives - Build for customer and quality, not for VC hype $1B in revenue, profitable, zero outside funding.

Surge has scaled to $1BN in revenue with $0 funding. Scale AI, their closest competitor, raised $1.6BN to get to $850M in ARR. Surge is the most underdiscussed story in tech. Tomorrow, I have their founder on 20VC for a special one. What are the must ask questions?

"We all know about Scale and its epic $14B investment from Meta. But what about @HelloSurgeAI 'quietly' doing $1B+ ARR in same space -- with zero VC fundraising??"

$1B in ARR. Profitable. No funding. 5 years. ~100 people. Today, I’m insanely proud to announce a partnership between @GrowthXAI and @HelloSurgeAI.

@echen and team took a completely opposite approach (in all the right ways IMO). Fast forward to today and they are the biggest provider of frontier data that power most of the models we use everyday and… They are the fastest company ever to reach $1B in ARR without funding.

Sometimes the best companies are the ones nobody's hyping.

Big NEWS! @GrowthXAI raised $12M Series A led by @MadronaVentures. We scaled to $7m+ profitably in less than a year. We get to be growth-as-a-service for companies like Ramp, Webflow, Reddit, Superhuman, Abnormal, Bolt, Vapi and many others.

With this funding, we're accelerating our platform vision to tackle more types of services and will soon open it up more broadly. The future isn't AI replacing experts. It's AI turning your organization's best thinking into repeatable systems.
