A LITTLE BIT UNCOMFORTABLE

Moving into a leadership role means your relationship with fear shifts. You now have to also help others take risks. Even asking simple questions can be a great starting point to encourage the people you are invested in to push themselves. It is important to learn to spot fear in others so you know when to step in to move things forward.

WHAT'S NEXT AFTER YOU LOSE SOMEONE'S MONEY

After losing an investor's money, founders should follow up with honest self-assessment and feedback requests to preserve relationships and improve future endeavors. Engaging in open communication with past investors can mitigate misunderstandings, demonstrate growth, and possibly spark interest in new ventures. This proactive approach ensures prior investors can accurately represent the founder to new potential backers, maintaining the founder's reputation.

THE BIFURCATION IN THE AI MARKET

The AI market has split into two. Enterprises are paying for precision with proprietary models, while consumers are using cheaper open source models for play. Proprietary providers don't need to compete on price because they've won the segment that pays. This is why, despite open source models being significantly cheaper, proprietary providers haven't lost pricing power.

LONG LIVE SYSTEMS OF RECORD

Everyone keeps saying AI agents will kill systems of record. The opposite might be true. Ask sales what your ARR is, and you get one number. Ask finance, and you get another. Humans can talk it out - agents can't. The more we automate, the more someone needs to decide what the correct answer actually is.

THE REAL STATE OF SEED TODAY: THE TOP 10 LEARNINGS FROM 50,000 STARTUPS, PER CARTA'S LATEST DATA

The seed market is healthy but bifurcated. AI companies are operating in a different universe than everyone else, who is competing for a smaller share of attention with leaner teams and longer runways. SAFEs have become completely standardized, and solo founding is increasingly viable, but remains a handicap for fundraising. The fundamentals are still the same: build something people want, get to metrics that matter, and raise when you have the leverage.

THE AI VALUE GAP: WHERE DOES THE $7,000 PER SEAT GO?

OpenAI claims that AI saves the average white-collar worker 54 minutes per day. Currently, vendors capture 10% to 15% of that value, leaving employers and employees with 85% to 90% value capture. This gap suggests that significant pricing power remains untapped. Bundling further complicates the picture - there appears to be a market for best-in-class vertical tools even when bundled alternatives exist.

THE AGE OF COMPOSABLE SOFTWARE

Software has always faced a brutal trade-off - you can have customization or affordability, never both. Affordability always won. That's why personal computers were never really personal, and most apps follow "one codebase to rule them all." AI changes this math so dramatically that the trade-off might finally break down. Instead of killing software, AI could make it infinitely personalized - built for an end-market of one.

PLAY RIGGED GAMES

Unfair advantages come in three flavors: product insight, go-to-market edge, or technical moats. One common thread among successful founders is an obsession that rational people would walk away from. They solved problems they couldn't stop thinking about. Find your edge and stop fighting fair.

HOW MUCH EQUITY CAN YOU GIVE TO EMPLOYEES BEFORE IT'S A PROBLEM?

The median public tech company spends 12% of revenue on stock-based compensation. Sounds outrageous until you see that actual shareholder dilution is under 2%. The math is simple - SBC is measured against revenue, dilution against market cap. A company trading at 4x revenue spending 12% on SBC only dilutes 3% of market cap. The companies getting killed aren't spending 20% on SBC. They're the ones growing 5% while pretending they're still a growth story.

AI PULLS VC AND PE INTO THE SAME ORBIT

AI is transforming labor-heavy service sectors, putting SMB and mid-market businesses within reach for tech startups and collapsing the historical divide between venture capital and private equity. PE funds are becoming distribution channels for AI products, while founders use PE portfolio pages as idea maps as AI expands TAM for legacy software categories. AI native rollups accelerate the convergence as VC-backed platforms acquire traditional services firms and rebuild them around automated operations.

THE MAP IS NOT THE TERRITORY

VCs treat the power law like a selection tool when it's actually just a description of what happens after the dust settles. They look at seed-stage startups and ask, "Is this a power law company?" - but that's a category error. Uber looked like a black car service for rich people. Airbnb was for travelers who couldn't afford hotels. Both got passed because investors couldn't model a $10B outcome. The irony is that power law returns almost always come from market creation, not capturing predictable share of existing markets.

8 TAKEAWAYS FROM CARTA'S STATE OF SEED REPORT

Seed funding is back to near-peak levels, but the money is significantly harder to touch. Investors are piling more cash into fewer rounds, essentially ignoring everything outside of SF and NY. The most telling stat is headcount: the average seed startup has slimmed down from 10 people to just 6, likely because AI is picking up the slack. However, don't let the tools fool you into going it alone: VCs still fund co-founders at double the rate of solo acts, despite the data showing that 25% of those partnerships end in a breakup by year four.

HARDWARE IS A FRUIT

The feedback loop for physical products is speeding up. We used to assume that building hardware meant long timelines and high costs for every mistake. That dynamic is fading. Modern simulation tools and AI assistants now let engineers iterate on physical designs almost as fast as they write code. The barrier to entry is shifting from manufacturing logistics to pure design capability.

DRIVING EXTREME CLARITY

At your startup, it's important to recognize that a "messy yes" is often more dangerous than a hard "no." Teams tend to drift into "strategic ambiguity" - nodding along to avoid conflict without actually agreeing on the trade-offs. The fix is to force the friction upfront: make the team stack-rank priorities (no ties allowed) and write down exactly where you disagree.

RL IN REAL LIFE: DURABLE MOATS

Reinforcement learning (RL) has gone from being a promising path towards general intelligence to a taboo phrase over the past year. It has proved highly effective inside AI labs, but outside of the labs, its use cases remain surprisingly underdeveloped. Most efforts appear to be largely experimental and have yet to scratch the surface of the sophisticated techniques used within the frontier labs. This post looks at the intricacies of building effective RL approaches, assesses current use cases, and discusses what founders should consider when commercializing RL-based systems.

A FEW THOUGHTS ON CONVICTION

The venture capital industry is full of sheep. Funds blindly follow others without thinking for themselves. They lack all conviction. As a result, they don't blaze new trails - and blazing new trails is the only way to earn outsized returns in a hyper-competitive market as an investor or an operator.
