Every B2B company hits the same inflection point — enterprise customers show up and they need SSO, directory sync, audit logs, and role-based access before they'll move forward. Most teams lose months building that infrastructure. It doesn't have to be that way.

DIGITAL TWINS ARE ABOUT TO MATTER FOR AI AGENTS

When a key employee leaves, their judgment and pattern recognition usually walk out the door with them. Digital twins are being repurposed from manufacturing (where you build a digital copy of a physical asset) to capture that kind of workflow knowledge, things like quote-to-cash, onboarding, any process that lives in someone's head, so an agent can run it.

SERVICES: THE NEW SOFTWARE

The next $1 trillion company will be a software company masquerading as a services firm. In 2025, the fastest-growing AI companies were copilots. This year, many will try to become autopilots. This will result in a dilemma where selling the work means cutting their own customers out of doing it.

FROM HIERARCHY TO INTELLIGENCE

Companies move fast or slow based on information flow. Hierarchy and middle management impede information flow. For thousands of years, there was no alternative to hierarchical systems, and layers were needed. AI removes the need for humans operating in these layers.

HOW FOUNDERS GET BETTER AT STORYTELLING

Storytelling is a skill that compounds. It starts with articulating your story to yourself, then editing and clarifying it until the story becomes both simple and specific. As your story gets clearer, everything downstream gets easier. This takes time, so find opportunities to practice.

WHAT'S GTM AS PRODUCT?

Most teams treat GTM like a junk drawer of sales scripts, one-off automations, and whatever worked last quarter. Teams should treat GTM like an actual product, with memory, workflows, guardrails, and version control baked in. That's where "vibe marketing" needs to end up if it's going to last.

TRADER MINDSET

The "Trader Mindset" suggests a cultural shift towards short-term gains over long-term investment, driven by trends like crypto and day trading. This approach explains job-hopping, multiple VC investments in similar spaces, and the quick pivot from web3 to AI. While it can lead to financial success, true greatness and enriching relationships come from sustained commitment and belief.

THE ONLY MOATS THAT MATTER NOW

AI is compressing the value of "hard to do" but not "hard to get." Five moats that still hold up: compounding proprietary data, network effects, regulatory permission, capital at scale, and physical infrastructure. If your moat is complexity or execution speed, it's shrinking. If it's access to something scarce, it's probably getting stronger.

UNLOCK THE DATA YOUR PRODUCT CAN'T SEE

Most tools are still locked to their own database, blind to everything users already have in Slack, GitHub, Salesforce, Google Drive, and dozens of other apps. That's the ceiling on what you can build.

YC W26 DEMO DAY: 14 COMPANIES HIT $1M ARR BEFORE PRESENTING

190 companies presented this week. 85% were AI-first. 14 hit $1M ARR before demo day, the highest ever for any YC batch. The bigger signal here is that the bar for what counts as "early stage" keeps moving. $1M ARR used to be a Series A milestone. Now, it's table stakes for a demo day presentation.

REFLECTIONS ON THE STATE OF THE SOFTWARE AND AI MARKET

The AI market isn't the same as the Dotcom bubble of the past. The technology is still early, and demand is pulling spending forward. The software selloff is real, but it won't hit every layer equally, as each has its own moats. Across the last few technological revolutions, the companies that became durable winners were predominantly founded in years four and five of each platform shift. We are now in that window for AI.

SELLING TO AI AGENTS

Every major tech shift creates a new growth channel. AI is becoming a decision-maker - they're starting to choose products. This new growth channel is embedding products directly into the AI tools that people use. This impacts strategy, product, and engineering. The companies that will be marketing to the interface layers that make decisions on users' behalf.

PER TOKEN PRICING IS COMING FOR EVERY AI COMPANY

The hardest problem in AI right now isn't the model, it's the pricing. In traditional SaaS, you could underprice a seat, and it didn't matter because the marginal cost of serving another user is basically zero. Now every agent action, every "magic" feature triggers real inference costs on the backend. Price too low and you're literally paying customers to use your product. Price too high and you lose to the competitor who figured it out first. Per-token and credit-based pricing models are about to become the default because they're the only ones that align cost structure with value delivered.

WHO TO HIRE AT STARTUPS: ANTIFRAGILE PEOPLE

Antifragility is the premise that some things, including people, improve from stressful situations. Disorder and uncertainty are the rule at startups. Over time, antifragile people will consistently improve their value/skills due to the continued exposure to a startup's disorder.

THE ONLY PATH LEFT IN SOFTWARE: ACCELERATE OR DIE

Software companies have three paths right now: accelerate revenue 10%+ YoY through AI-native products, get stuck in the messy middle, or rebuild to 40-50% operating margins. Even the profitability path is deceptive. Most companies that look profitable on FCF margins are still in the messy middle once you account for stock-based compensation. The only real option is to accelerate. If you're not rewriting your product around AI, you're choosing a slow death.

AI COMPANIES ARE BUILDING FOR THE WRONG USERS

The gap between the early adoption and maturation phases is closing fast. The early adopters of AI have gotten the industry to where it is now. The next phase of growth will come from users who are curious but skeptical, willing to try but not interested enough to figure out how to work around the rough edges of the technology. This audience will determine whether AI delivers on its productivity promises.

AI FEATURES ARE ERODING YOUR SUBSCRIPTION APP'S MARGINS — HERE'S HOW TO FIX IT

AI features introduce variable costs that scale with user engagement. This disrupts the near-zero marginal soft model of traditional subscription apps. The most successful businesses are designing their entire systems around the economics of usage. Teams need to manage AI the same way they manage acquisition spend or infrastructure. Consider whether the AI feature is worth the cost - the improvements from implementing AI need to be measurable.

THE IMAGINATION CHASM: WHY 99% OF USEFUL AGENTS HAVEN'T BEEN BUILT YET

Most industries still can't define what an "agent" actually is. You can't build what you can't picture. This post lays out the six things still missing before agent-to-agent economies work: a communication layer (MCP/A2A), vendor-agnostic infra, dynamic auth, a payments layer, a marketplace, and real benchmarks. OpenClaw expanded imagination, but it's still the first 1%.

AVOIDING THE EYE OF SAURON

Founders in AI face heightened competition from incumbents, startups, foundation models, and empowered customers, risking obsolescence if their products remain at the workflow level. Companies building horizontal applications for high-agency, high-capability customers are particularly vulnerable, as these customers can easily replicate such tools. Founders must prioritize deep domain mastery, addressing human-centric problems, and developing chassis products to maintain a competitive edge.

SAAS WAS ABOUT UNBUNDLING. AI IS ABOUT REBUNDLING

The SaaS playbook was simple - own one workflow, expand from there. AI companies are doing the opposite - they're expanding into adjacent categories almost immediately because the cost of building is near zero. Models change every 42 days now, and buyers would rather trust one platform for 3-5 years than stitch together a best-of-breed stack that's outdated by next quarter.

2026 STATE OF GTM: THE BENCHMARKS THAT ACTUALLY MATTER

Companies under $100M ARR are accelerating again, likely driven by AI-native companies growing abnormally fast. CAC payback period is the metric to watch - revenue durability is uncertain, and shorter contract lengths are becoming the norm. GTM efficiency on AI products with 30% gross margins looks very different from that of traditional software with 75% margins.
