FINTECH'S MOATS DON'T COMPILE

Fintech's primary moats reside in regulatory permissions, credit data, and risk-bearing capacity rather than replicable software code. While AI compresses margins for pure SaaS by commoditizing code, it strengthens fintechs that own their licenses and underwriting history. Competitive advantage is shifting away from UI toward those who control the "fin" side by managing money movement and proprietary risk models that AI optimizes but cannot replace.

MANAGEMENT IN THE AGE OF AI

Managers must be builders in 2026 because not building now is the bigger waste of time. They need to learn AI tools, and building is often the most efficient path for the team. The ability to build will be a key differentiator between teams that win and teams that drown in their own output. The gap between good management and bad management is now a lot wider.

BUILDING WHERE THE BUYERS ARE

For the last twenty years, the hardest part of building a tech company was the development itself. AI is dissolving that constraint. Companies no longer need to have large teams to ship products. This means Silicon Valley may no longer be the center of the tech industry. Companies needed to be near the engineers when the hard part was writing code, but they will now move to where the buyers actually are.

HOW YOU SOURCE GREAT DESIGNERS

If you want the best designers, you have to go where they are and be someone they want to talk to. X is a good platform for designers who are exploring startup opportunities. Look for designers who actively follow tools and communities that signal taste. Most self-aware designers move quietly through trusted networks. Founders need to be plugged into those networks before they need them.

BEN HOROWITZ ON WHAT MAKES THE BEST FUNDRAISING PITCH

The fundamentals haven't changed nearly as much as people think. Strategy is still about articulating a clear 'why'. Product management is still about shipping the right product at the right time. The best fundraising pitch is the one you actually believe. The landscape around the fundamentals has changed, but there are still massive new opportunities hiding in plain sight.

THE NEW GTM PLAYBOOK: OUTBOUND ALONE WON'T CUT IT

AI has commoditized cold outreach, forcing a shift from outbound-only tactics to a multi-channel flywheel of content, community, and retargeting. ColdIQ nearly doubled revenue by using content to prime prospects, resulting in conversion rates 3x higher than traditional cold contacts. Success in 2026 requires building this organic distribution early, as the 6-12 month startup time creates a massive lead over competitors still relying on saturated outbound channels.

HOW POSTHOG BUILT A MARKETING ENGINE THAT ACTUALLY DRIVES GROWTH

Tens of millions in ARR, $1.4B valuation, zero outbound sales calls ever. Usage-based pricing with a generous free tier means one engineer installs it for a side project and it spreads inside the company the way Figma did. Their newsletter has 75K subscribers and never mentions PostHog - just teaches engineers how to build better products.

FISH AUDIO

Expressive text-to-speech and voice cloning platform.

NOTTE

Turn any website into a callable API.

FIGR

Spot UX blind spots before writing code.

STRATEGIC CHOICES: WHEN BOTH OPTIONS ARE GOOD

"Customer-first" isn't a strategy - nobody picks "customer-last." Real strategy means choosing between two good options where smart companies exist on both sides. "All-in-one" means you personally own every feature request forever. "Infinitely extensible" means your UX becomes a patchwork quilt. If the opposite of your strategy sounds stupid, you haven't decided anything.

REVENUE ADDICTION KILLS COMPANIES

If revenue is your North Star, your company is destined to die. Revenue-addicted companies kill every initiative that doesn't move the number this quarter, which is exactly the opposite of what you need during the AI transition when you have to make big product bets. Lovable swapped its North Star to daily active apps and built a qualitative "Lovable Score" combining NPS, PMF score, effort score, and CSAT. Revenue still matters, but it's the output of the system, not the thing you optimize for.

PRODUCTIVE INDIVIDUALS DON'T MAKE PRODUCTIVE FIRMS

Individual AI gains often create organizational chaos and "slop" rather than firm-level value, mirroring the 30-year lag in productivity seen during factory electrification.

SERVAL'S PATH TO PRODUCT-MARKET FIT

"What's your biggest pain point?" is dead as a discovery question.

BEING A “SYSTEM OF RECORD” WON'T SAVE YOU. IT'LL JUST MAKE YOUR DECLINE MORE COMFORTABLE

System of Record businesses that don't own the AI layer on top of their platforms will see spend flowing around them - while they will get renewals, they won't see growth.

AGENT SKILLS ARE THE RECIPE. VERTICAL AGENTS ARE THE CAKE

Selling skills is like selling the recipe, and you want to be in the cake business.
