Agents are eating discovery, so what happens to marketplaces? I see two futures: 1/ Marketplaces build their own agents, and each one stays the destination for search 2/ Agent-to-agent infra is built out and my agent searches across marketplaces and suppliers via API Future 1: Each marketplace has an agent Resy has an agent. I text it in iMessage, use it in the app, or have my personal agent talk to it. Resy is still the destination for reservations in my mind. > Likeliest where brand and taste matter or supply is exclusive: restaurants, events, fashion Future 2: Marketplaces become suppliers behind my agent I tell my agent I need a doctor. It checks my insurance, location, and medical history, queries across marketplaces/practices, verifies credentials, and brings back three options. I approve one, and booking happens between agents. I never see the exchange. My agent is my entrypoint, and the marketplace is a supplier behind the scenes that I never see. > Likeliest where supply is fragmented and fit matters more than brand: care, in-home help, moving, home repair IMO these aren’t mutually exclusive. Both can exist, but they compete for the entrypoint. Under 1, the marketplace still owns the relationship and brand in my mind. Under 2, it’s one source - supply becomes headless to me. Today, marketplaces do four main jobs: discovery, trust, transaction, and operations. With discovery melting away, the value moves to what sits underneath the marketplace: > Trust and verification layers agents can query (credentials, identity, insurance, outcomes) > Supply-side agents that manage availability, pricing, and listings across channels > Structured-data registries for fragmented categories (care, home services, specialty health) > Agent-to-agent transaction rails: payments, dispute resolution

Dee Hock (Visa founder) built a world in which you can transact with anyone, anywhere, in a trusted fashion. His vision for a global network transcends the business that Visa became: it created many trillions in shareholder value for companies he could never have envisioned and never could have existed without it. His framework below is must read for anyone trying to comprehend our current moment.
One of my favorite Dee Hock frameworks is what he called trying to master the "four ways of looking at things: As they were, as they are, as they might become, and as they ought to be." Through that lens, it's easy to see AI as a technology driving significant change between the way the economy worked five years ago and the way it works today. It's also easy to speculate on where it might lead, especially given the many real risks and challenges around AI alignment. But I'd argue the most important thing anyone can do is develop a perspective on how it "ought to be," and then build toward that. To me, AI shouldn't just be a technology that accelerates the automation of tasks humans used to do. It ought to supercharge our ability to coordinate economic activity, giving people leverage to connect their unique expertise, taste, and data traces with the people and companies that need them. While the AI data labeling ecosystem is one of the first examples of new economic activity with people and companies getting paid by labs for their expertise or data traces, I'd love to see an explosion in AI-enabled freelancers across other sectors of the economy.

PFPs make a lot more sense for agent swarms than for people
NFTs are an area of crypto that i think deserves another look the 2021 boom and subsequent crash left a lot of people with a negative view of them, but the underlying concept still makes sense to me as more businesses move onchain, NFTs could become a useful way to represent ownership, experiment with revenue sharing and build communities around products i expect there's still a lot of room for experimentation beyond the NFT models we saw last cycle

How do you pay out pesos in Mexico without keeping pesos in a Mexican bank account? On @TokenizedPod, @cuysheffield put that question to @manueljgodoym of @Felixpago. Wise-style remittance models fund local accounts in every corridor ahead of time. Félix sends USDC and buys pesos in a 24/7 market when the payout happens, at an FX rate Manuel says comes close to interbank. Cuy names the trade-off: no capital sits idle in each country, but you need a liquidity partner on the receiving side.

Prior tech platform shifts (web, mobile) have involved: (1) a new technical capability; and (2) a new distribution mechanism In AI, we've seen a lot of (1) - and little of (2) Agents are primed to fix this, and will become arguably the best distribution channel of all time

Incredibly high signal podcast on the evolving payment infrastructure powering agentic commerce with @terryangelos and @arampell
The wallet wars are here. Very Good Security chief strategy officer Terry Angelos joins a16z's Alex Rampell, his TrialPay co-founder from back in 2006 (TrialPay was later acquired by Visa), to discuss how agents are learning to spend money. "Agents have all of a sudden become significantly more helpful and useful because they effectively have arms and legs, which are payment credentials." VGS holds the payment credentials behind about 1/3 of all e-commerce, and now it's helping AI agents pay merchants. If you've bought anything online, there's a good chance VGS has already helped keep your card safe. In the last three months, Terry says agents went from "spectators to actors." Once an agent has your payment credentials, it can book the piano teacher it previously could only find and recommend. Now Stripe's Link, Shopify's Shop Pay, and PayPal are racing to connect to agents. It's all headed toward open standards from the card networks: agentic tokens that let an agent pay with your actual card. VGS went from zero agentic tokens to a few million a week in three months. 0:55 From TrialPay to Visa to VGS 2:05 How VGS vaults 1/3 of e-commerce 6:05 Why big merchants use 3-5 processors 9:55 Why AI agents need a payment vault 12:15 Agents go from "spectators to actors" 13:40 The wallet wars, old and new 19:55 Walled gardens vs open standards 23:55 How agents can pay with your real card 26:40 Your saved card goes multiplayer 29:40 How do you trust an agent's purchase? 32:35 Who pays when your agent gets it wrong 35:40 Why Amazon blocks agents 39:50 What's overhyped and underhyped 43:35 When merchants get agents too 45:40 Why agents could break card rewards 47:00 VGS's eras: vault, updates, network @terryangelos @arampell

Great framing - “Your product now has to sell itself twice. First the agent has to pick it, then the human has to trust that pick enough to say yes.”
More SF observations: 1. Seeing the word "inference" on billboards in SF still blows my mind. 99.9% of america has no idea what inference is and I wonder how many know what an agent is. Will Muse, Instinct, Dots etc will change that over the next 12 months? 2. You know who doesn't get enough credit? Manus. In March 2025 they shipped the blueprint for AI agents: every task gets its own computer in the cloud, you can watch it work, it writes a todo list and checks it off, and you walk away while it finishes. So much of what we use today runs on those ideas! 3. Your product now has to sell itself twice. First the agent has to pick it, then the human has to trust that pick enough to say yes. 4. I was talking to a guy who told me we should just destroy all the data centers. I think that sentiment is more common than people in SF realize. You can already see some of the big AI companies adjusting positioning their AI as something that helps people and gives them more time/cures for cancers etc. 5. AI is making people work 5x faster (at least), so for freelancers/agencies that charge per hour you're earning 5x less per unit of work. But your rate is the same? I think a lot of freelancers and agencies are about to have to rethink how they price. 6. Running a company now feels kinda dystopian sometimes, especially with a small team of a few humans and a lot of agents. Some days the Slack channel is mostly bots reporting to each other, and you're the only one in the room with a pulse. 7. Every product company is turning into a product studio. I see it firsthand as a co-founder of @meetLCA , which is basically a Labs as a Service company incubating new products for companies. (DM me if you want to work together in 2027). 8. Personal software is exploding. People at every company are building their own little tools for their own jobs. It's amazing for productivity and a nightmare for IT, because nobody knows what's running or who owns it. 9. Revenue per human is the new flex. Founders used to brag about headcount. Now they brag about how much they're doing with how few people. 11. More founders are using agents for customer research. Agents run the interviews, read every support ticket and summarize what people are begging for. Synthetic market research is the new thing. 12. Shipping technology that actually takes 3-6 months with unique partnerships that are hard to replicate. So, partnerships are sooo back! 13. Insane amount of young people (22 or younger) making absurds amounts of money. At least it feels that way. Never seen anything like that, even during mobile era. 14. Only 2% of the US is paying for AI products, but it feels like 110% SF is. 15. Advice for college grads used to be “follow your passion” and now it’s follow careers that are not document- driven, rules-bound and verifiable 16. Seeing the word inference on billboards in SF still blows my mind. 17. Agents paying for things feels futuristic. I think its coming, only a matter of time, but I’m wondering when it becomes mainstream. 2027? 18. Lots of talk about proactive agents being the next phase of personal agents. Right now you ask your agent to do something. In 2027, it’s all going to be about noticing things (context/memory) and acting first. "Your flight got delayed, I already rebooked you." 19. The quote "what the smartest people do on the weekend is what everyone else will do during the week in 10 years." by Chris Dixon. It feels like that length of time isnt 10 years anymore, its 12 months. 20. This is the most asymmetric window I've ever seen in business. My DMs are open. Respond to the most interesting ones. Loved my trip to SF. Until next time. Maybe NYC next? Thank you for everything. I'm rooting for you.

Love @alexandr_wang's positioning that "Muse makes you money." But most of the use cases I'm seeing today (canceling subscriptions, renegotiating bills) are really "Muse saves you money." Has anyone actually used Muse to generate income? If so, how?

Cool concept, excited to see "groupon for agents" experiments that create agent collectives to aggregate purchase demand and then negotiate discounts with merchants across verticals Instead of everyone booking travel through their agent solo, why can't I add my agent to a collective that can buy out a resort for a weekend at a discount

After a great conversation with @hrkrshnn from @cantinaxyz about the agentic cyber arms race, one idea I keep coming back to is that it's turning into a cost war. Models are now good enough to find most vulnerabilities if you spend enough tokens looking. That puts defenders in a tough spot. If they default to frontier closed models for pen-testing and defense, they burn a lot on expensive tokens. Meanwhile attackers can run swarms of agents on cheap models for as long as it takes. It's the drones vs aircraft carriers problem in cyber. When cheap drones need expensive missiles to shoot them down, defense eventually becomes unaffordable. The cyber companies that win will own their data. Every customer audit feeds a pipeline that post-trains their own models on open weights, getting close to frontier performance at a fraction of the cost. Lower cost means they can search longer and defend longer without breaking the bank. In the age of agents, the advantage goes to whoever can afford to keep looking.
