TLDR Founders 2026-03-23

As your business grows, your payments and billing infrastructure can become a bottleneck. While some struggle with operational complexity, companies like ElevenLabs and Runway built systems that scale smoothly with user growth.

Stripe's scaling AI playbook unpacks those companies' blueprints for hyper-growth and offers suggestions to reduce operational drag. These leaders automated billing complexity and designed pricing strategies that adapt with their business. As a result, teams can focus on building next-generation AI products, while their billing and revenue operation largely operates in the background.

85% of YC's W26 batch is AI-first, with 56 of 198 companies building fully autonomous agents explicitly positioned as AI employees targeting every $50-150K knowledge worker role, from AI accountants closing books without human touch to AI law firms staffed entirely by models. Healthcare is the largest vertical with 22 companies going after clinical work itself rather than EHR wrappers, while 13 robotics companies are actively deploying alongside a full picks-and-shovels ecosystem for physical AI.

Every major technology era follows the same arc - consumer first, then enterprise, then infrastructure - and AI is no exception. The first wave of winners built directly for consumers, but the pattern from prior eras says the durable businesses will be the ones building tooling and infrastructure layers underneath. If you have seen this cycle before, the playbook is clear: the picks-and-shovels companies outlast the gold rushers. Recognizing where you sit in this arc shapes when to enter, who to build for, and how to time your raise.

Revenue and bank balance stop being enough the moment an investor or board member asks a hard question. A fully linked FP&A model connects revenue forecasts to hiring plans, burn rate, and fundraising timelines in a single living document - change one input and every downstream assumption updates automatically. This is what lets you stress-test scenarios like a churn spike or a delayed round before they actually happen. It is also the kind of financial infrastructure sophisticated investors expect to see when you are defending your raise.

To vet a co-founder, work directly with them on a real project to gauge compatibility and efficiency authentically. Lay the groundwork for collaboration by evaluating past outputs, seeking references, and discussing values to identify potential long-term challenges or alignments. Avoid superficial interviews, and prioritize genuine trials to make informed decisions about meaningful partnerships.

Posting times, hashtag counts, and emojis have almost nothing to do with LinkedIn virality - emotional architecture does. The gap between posts that explode and posts that die in silence comes down to how the information makes people feel, not what information is being shared. Think identity validation, status signaling, and tribal belonging baked into every sentence. One company went from crickets for 8 months to booking 96 calls in a single month after rebuilding content around emotional psychology instead of information delivery. Spend less time on the insight and more time engineering the feeling.

Companies no longer need engineers to win. They need someone who treats deployment as a core job function - an agentic deployment expert. These hires are worth more than anyone else you can hire right now. They don't need to be technical, they just have to know how to use AI tools to get to deployment. Companies that don't hire an agentic deployment expert risk wasting years of work.

Supermemory is an agent memory system that achieves ~99% SOTA accuracy.

Status update 1:1s are a waste of everyone's time, and the fix is simpler than you think. The shift that matters is moving from "what did you do this week" to questions that uncover blockers, ambitions, and candid feedback - the things people will not volunteer in a group setting. A well-run 1:1 builds trust, surfaces problems weeks before they escalate, and develops your team in ways that compound as you scale. Getting this cadence right early creates a management culture that becomes a genuine competitive advantage.

Most people don't like computers and only tolerate them because they have to. They likely would rather not think about them at all, given the choice. These people might use AI, but they won't be using the technology to build their own systems and tools to maintain. They just want to get the task done.

Silicon Valley treats scale like a moral good when it's actually just a strategic choice.

The "cold start" trap hinders promising social infrastructure by requiring mass initial adoption for value, causing most projects to fail.

Vibecoding has quietly turned software creation into a creative act, and that shift puts a large class of consumer utilities on shaky ground.
