We just published Stripe's 2025 annual letter: stripe.com/annual-updates….

When @karpathy built MenuGen (karpathy.bearblog.dev/vibe-coding-me…), he said: "Vibe coding menugen was exhilarating and fun escapade as a local demo, but a bit of a painful slog as a deployed, real app. Building a modern app is a bit like assembling IKEA future. There are all these services, docs, API keys, configurations, dev/prod deployments, team and security features, rate limits, pricing tiers." We've all run into this issue when building with agents: you have to scurry off to establish accounts, clicking things in the browser as though it's the antediluvian days of 2023, in order to unblock its superintelligent progress. So we decided to build Stripe Projects to help agents instantly provision services from the CLI. For example, simply run: $ stripe projects add posthog/analytics And it'll create a PostHog account, get an API key, and (as needed) set up billing. Projects is launching today as a developer preview. You can register for access (we'll make it available to everyone soon) at projects.dev. We're also rolling out support for many new providers over the coming weeks. (Get in touch if you'd like to make your service available.) projects.dev

@RichardMCNgo @freed_dfilan The food was all English!

@freed_dfilan @patrickc huh, maybe I’m underestimating how segregated different Twitter bubbles have become. A version of the meme relevant to your biblical interests btw is people analogizing our situation to Esau’s: trading one’s birthright for tastier food.

There’s a lot of discussion in these parts about all the things that are degrading (public safety, disorder, architecture, institutions, …), but it is remarkable how much better food has gotten over the course of my lifetime. I was recently traveling in the UK, and even in small towns, the restaurants were consistently great. (I particularly recommend Isla in Durham.) Ireland has similarly improved by leaps and bounds. The US is very good these days. Has there ever been a better time to eat?

Very enthusiastic about what @centivax is doing. We still suffer from an outrageous number of infectious diseases. axios.com/pro/biotech-de…

Why do new buildings seem, on average, uglier than old buildings? We discuss some options: - Survivorship bias: only the beautiful old buildings have survived (we reject this option); - Cycles of taste: everyone always finds new buildings uglier (we mostly reject this too); - Ornament became too expensive because of rising labour costs (we reject this); - Ornament became too cheap because of mechanisation and then became low status (we reject this); - Some sort of Protestant or Puritan anti-beauty inheritance (we are doubtful); - Some kind of elite status game, perhaps a response to democratisation or elite overproduction (we think there is promise here, but serious work is needed on the details). I discuss this and more with @Aria_Babu and @bswud. Apple podcasts: podcasts.apple.com/gb/podcast/did… Spotify: open.spotify.com/episode/2pIka6… Youtube: youtube.com/watch?v=qvueKt…

@dwlz @stripe Good feedback! @kevinyien

Feedback for @stripe folks: it's counterintuitive that contraction bars on the ARR growth chart are green and the expansion bars are red. Whoever works on this, can you please invert the colors?

Excellent choice by OpenAI!

Have wanted something like this for ages — it looks great.

@jeff_weinstein Can we have this but for noise?

Just discovered Ruskin's The Nature of Gothic. Remarkable essay: #page151" target="_blank" rel="nofollow noopener">gutenberg.org/files/30755/30…. "The charts of the world which have been drawn up by modern science have thrown into a narrow space the expression of a vast amount of knowledge, but I have never yet seen any one pictorial enough to enable the spectator to imagine the kind of contrast in physical character which exists between Northern and Southern countries. We know the differences in detail, but we have not that broad glance and grasp which would enable us to feel them in their fullness. We know that gentians grow on the Alps, and olives on the Apennines; but we do not enough conceive for ourselves that variegated mosaic of the world’s surface which a bird sees in its migration, that difference between the district of the gentian and of the olive which the stork and the swallow see far off, as they lean upon the sirocco wind. Let us, for a moment, try to raise ourselves even above the level of their flight, and imagine the Mediterranean lying beneath us like an irregular lake, and all its ancient promontories sleeping in the sun: here and there an angry spot of thunder, a grey stain of storm, moving upon the burning field; and here and there a fixed wreath of white volcano smoke, surrounded by its circle of ashes; but for the most part a great peacefulness of light, Syria and Greece, Italy and Spain, laid like pieces of a golden pavement into the sea-blue, chased, as we stoop nearer to them, with bossy beaten work of mountain chains, and glowing softly with terraced gardens, and flowers heavy with frankincense, mixed among masses of laurel, and orange and plumy palm, that abate with their grey-green shadows the burning of the marble rocks, and of the ledges of porphyry sloping under lucent sand. Then let us pass farther towards the north, until we see the orient colors change gradually into a vast belt of rainy green, where the pastures of Switzerland, and poplar valleys of France, and dark forests of the Danube and Carpathians stretch from the mouths of the Loire to those of the Volga, seen through clefts in grey swirls of rain-cloud and flaky veils of the mist of the brooks, spreading low along the pasture lands: and then, farther north still, to see the earth heave into mighty masses of leaden rock and heathy moor, bordering with a broad waste of gloomy purple that belt of field and wood, and splintering into irregular and grisly islands amidst the northern seas, beaten by storm and chilled by ice-drift, and tormented by furious pulses of contending tide, until the roots of the last forests fail from among the hill ravines, and the hunger of the north wind bites their peaks into barrenness; and, at last, the wall of ice, durable like iron, sets, deathlike, its white teeth against us out of the polar twilight. And, having once traversed in thought its gradation of the zoned iris of the earth in all its material vastness, let us go down nearer to it, and watch the parallel change in the belt of animal life: the multitudes of swift and brilliant creatures that glance in the air and sea, or tread the sands of the southern zone; striped zebras and spotted leopards, glistening serpents, and birds arrayed in purple and scarlet. Let us contrast their delicacy and brilliancy of color, and swiftness of motion, with the frost-cramped strength, and shaggy covering, and dusky plumage of the northern tribes; contrast the Arabian horse with the Shetland, the tiger and leopard with the wolf and bear, the antelope with the elk, the bird of paradise with the osprey: and then, submissively acknowledging the great laws by which the earth and all that it bears are ruled throughout their being, let us not condemn, but rejoice at the expression by man of his own rest in the statutes of the lands that gave him birth. Let us watch him with reverence as he sets side by side the burning gems, and smoothes with soft sculpture the jasper pillars, that are to reflect a ceaseless sunshine, and rise into a cloudless sky: but not with less reverence let us stand by him, when, with rough strength and hurried stroke, he smites an uncouth animation out of the rocks which he has torn from among the moss of the moorland, and heaves into the darkened air the pile of iron buttress and rugged wall, instinct with work of an imagination as wild and wayward as the northern sea; creations of ungainly shape and rigid limb, but full of wolfish life; fierce as the winds that beat, and changeful as the clouds that shade them."

Worth playing around with wallet.tempo.xyz if you haven't. Very slick experience.

if you'd like to skip the line for accepting mpp via @stripe, email machine-payments@stripe.com with a sentence or two on your use case. (we're rolling out early access to the first ~100 users later today.)

Parallel is built for a world where agents are the primary users of the web. Agents can now autonomously pay per API call for web access via Parallel using MPP. parallelmpp.dev

Tempo is live!

@patrickjwitt @stripe Thanks for your leadership!

Thought it was fitting to spend St. Patrick’s Day with @patrickc and the @stripe team. Shame on us for not wearing green though. Grok, pls fix.

Everyone’s talking about the K-shaped economy—the rich pulling away while everyone else stagnates. In our inaugural Stripe Economics post, I take a look at @stripe + macro data, and I see the K on Wall Street, but not yet on Main Street: • The most profitable third of US public companies now account for ~2/3 of total market cap—the highest on record. • The S&P 500 rose 16.5% in 2025, and the top 1% own ~40% of all equities. So unsurprisingly the top 1% wealth share has risen (~2pp) since 2022. • BUT, Stripe data suggest lower-income household spending has been growing faster than high-income households over the last few years. • Wages tell a similar story: real earnings at the 10th percentile grew ~0.5pp slower than the 90th since 2022, but BOTH posted positive real wage growth. • Why? 1) The wealthy hold lots of equities but only account for ~25% of consumer spending. 2) Real wages at the bottom have been supported by continued labor market tightness post-pandemic, though this may cool.

Oh, and, one should follow @sytses to get a concrete sense for how the system suppresses experimentation and autonomy.

• According to the story, the dog's cancer has not been cured. • Absent all regulatory and manufacturing constraints, we could not just synthesize magic mRNA cancer cures. The technology is very promising, but it's not yet any kind of panacea. • The emergent system of regulators and manufacturers is indeed far too conservative, and small-scale experimentation is much harder than it should be. More people should read the first part of The Rise and Fall of Modern Medicine. Recommend @RuxandraTeslo, @PatrickHeizer for more.
