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.

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.

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.
