Today, we’re announcing our $160 million Series D funding, led by @kleinerperkins, with participation from @sequoia, @ThriveCapital, @jpmorgan, and @khoslaventures. 35,000+ financial professionals. 250+ institutions. One platform, purpose-built for finance. Thank you to our clients, our team, and our investors for their support as we continue building to raise the ceiling for what finance can accomplish.

We are honored to welcome Bob Iger back to Thrive. Bob leads with boldness and conviction because he knows what he is building and why. He is rejoining Thrive at a time when that kind of leadership matters most. We are living through the most consequential technology shift of our lifetimes, where AI will democratize access to intelligence in the way the internet democratized access to information. The companies that matter most will not just deploy the most advanced technology. They will understand what their customers truly want and place human judgment, taste, and craft at the center of what they build. Few people understand this as profoundly as Bob does. He has spent his career proving the things that feel the most human can also be the most eternal. Just as important, Bob embodies one of the firm’s core values; it is not just the business that we do, but how we do our business that will ultimately define our impact. We are deeply grateful to have him back and look forward to building together.

@DevinLewtan @lee94josh @turbopuffer @Sirupsen @afterimage @lee94josh can attest they are great, tho you might want to wait for second generation :)

@lee94josh @turbopuffer @Sirupsen need a few of these guys over at @afterimage studio

i'm excited to share that i’ve officially joined @turbopuffer to work on growth and brand! after consulting w @Sirupsen for the last few months, it's safe to say i've never met a team so hardcore & so whimsical at the same time viva la puff 🐡

we couldn’t afford the sphere so we got the next best thing costs less, hits harder

We waste too much time worrying about short term hype. Hyper-fixating on the news cycle isn’t going to fix the biggest problems facing society in the coming decades. The world needs more long term thinking. So we are launching Forecast 2050: a series of conversations with the thinkers, founders, and investors shaping the next 25 years. Thank you to @tylercowen, Scott Aaronson, @noor_siddiqui_, @soundboy, @matthewclifford, @devonzuegel, @CJHandmer, @MalcolmRifkind, Yanai Yedvab, @viswacolluru, @pablolubroth, and @PhilipJohnston for joining us. First episode with Tyler drops tomorrow. Stay tuned.

We are pleased to announce the close of Thrive X. Exceeding $10 billion, Thrive X comprises $1 billion designated for early-stage investments and $9 billion designated for growth-stage investments. We do not view this as a milestone, but as a commitment to the long work ahead. We view Thrive as a company. Our product is partnership - the willingness to commit deeply to a small number of founders, and to stand with them through momentum and adversity. This is the discipline we bring to our work, and the responsibility we accept when founders partner with Thrive. We do not hedge. Concentration demands loyalty to the founders and missions we back. In this moment, exposure alone is not a strategy. Judgment without commitment is not enough. Advantage will accrue to those who choose deliberately, commit deeply, and endure through difficult moments. Thrive was founded to be an enabling technology for the world we want to see. We are deeply aware that we are not the main character. The founders that we are fortunate enough to partner with are the artists. Our role is to help create the conditions where great work can come to life. We take a long view grounded in the belief that category-defining companies tend to create structural compounding advantages over long arcs. This fund reflects the continuity of our approach and the ways our work has deepened alongside the founders we support. We are grateful for the trust our Limited Partners place in us, and for the opportunity to work alongside those who are building with purpose, integrity, and courage. thrivecap.com/thrive-x

Molly Mielke McCarthy is on a quest to find exceptional people before the world catches on. I talked to @mollyfmielke about the art of "peopling", playing your own game, vocation, and why great founders are often the least legible. Today, she runs @mothfund, where she backs founders at the beginning. In the past, she's worked across design, product, and editorial at @figma, @NotionHQ, @stripepress, @browsercompany, and scouted for @sequoia. Her background in film and design echoes in the people she backs and in the quality of her curation and writing. Molly is people-centric yet fiercely individual, intuitive yet pragmatic, and truth-seeking yet full of care. We discuss: - Why it takes 3 months for her to know someone well enough to invest - Why authenticity is magnetic - The difference between agency and ambition - Why commerciality is a lens you can learn - Illegibility as private confidence, not public uncertainty - How your brand is a bell in other people's heads - Vocation as "stalking your calling" and then yielding to it - Why we should focus on doing something rather than being someone Timestamps: 0:00 - Opening Highlights 1:29 - Intro to Molly 3:36 - Thanks to Notion 5:14 - Start: People, Spikeyness, and Discernment 21:36 - Agency and Ambition 34:45 - Commerciality 49:19 - Investing, Feedback Loops, and Creating a Bat Signal 59:46 - Coaching and Working with Young People 1:06:54 - Self-Knowledge, Uncertainty, "Should," Others' Acceptance, Motivations 1:16:38 - Illegibility & Legibility, Principles, Authentic Service 1:29:28 - Friends, Seeing in the Third Person, Femininity in a Masculine World, Love 1:42:07 - Grab Bag: Art, Catholicism, Gratitude, Beauty @DialecticPod Ep. 38: Molly Mielke McCarthy - The Art of Peopling - is out now, below and on all platforms.

After ~two years of getting to know @Sirupsen and the @turbopuffer team, excited to officially puff

Today, Ramp raised another $300M at a $32B valuation. In the past year our revenue has doubled to over $1B, growing 10x faster than the median public SaaS. We all know money talks — we're teaching it to think. Getting big no longer means getting slow.

Today we are announcing our $1B Series C, but money isn’t the story. The story is what we’ll do with it, and the scale of the challenge ahead. Our mission isn’t constrained by capital, supply, or demand. It’s constrained by talent. To build America’s next great power company, we need the engineers, operators, and creatives ready to take on the challenge to join us. Power is the most important product in the world. It runs through everything: our homes, hospitals, schools, factories, and future. And the grid that delivers it is breaking. At Base, we’re building the future of power so human progress can accelerate. In the past two years, we’ve grown from an idea into one of the fastest growing energy companies in America. Now we’re entering a new phase of growth. Our first manufacturing site is rising in the heart of Austin, inside the former Austin American-Statesman printing press. Here we’ll build our own hardware to meet surging demand and scale nationwide. This is a key step in putting a battery on every home in the country. Few teams get to say their work powers human progress. We do. With a billion dollars of fuel, our next wave of growth will be defined not by capital, but by people who choose to step up, take ownership, and build the next great American power company. The old system is breaking. Come build the new one. Our Series C was led by Addition, with participation from both new and existing investors including Trust Ventures, Valor Equity Partners, Thrive Capital, Lightspeed, Andreessen Horowitz, Altimeter, StepStone, Elad Gil, 137 Ventures, Terrain, Waybury, Ribbit, CapitalG, Spark, BOND, Lowercarbon, Avenir, Glade Brook, Positive Sum, and 1789.

Five years ago, @tryramp launched its first product. Last month, we crossed $1B in annualized revenue—while generating free cash flow. Banks sell money. Ramp sells something different: time. Grateful to @leomschwartz and @packym for two of the most extraordinary deep dives yet

We're growing our AI eng team at @browsercompany! We have a bunch of new roles to help us move more quickly towards our vision of a new way of interacting with the internet in the AI era If you're interested, please reach out and apply!

Today, @tryramp raised $500M at a $22.5B valuation. Finance is at an inflection point. How does an industry change? Gradually, then suddenly. Decades where nothing happens; months where decades happen. Now, we’re teaching software to think like people. Exciting times ahead.

we’re ready to bring on another team member - full-stack eng w/ a love for reimagining + building new ways of operating, empowering creative minds, defining what modern product dev is, and working in a flat “collapsed talent stack” team to help unforgettable stories get made. DM!

Excited to share that we’ve raised a $40M Series B at @unifygtm to transform growth into a science. Many of the fastest growing companies like Cursor, Perplexity, Flock Safety and Airwallex choose Unify to reimagine growth in an AI-native world. This round comes just 9 months after announcing our Series A, and was led by Battery with participation from OpenAI, Thrive and Emergence 👇

Here’s my talk on @doji_com at the Humans in The Loop AI Conference.

I shared a bit about our vision and founding story, a product demo, and why now is the perfect time to build this. If you’re curious to learn more about Doji, this is a good place to start.

Today we’re launching @unifygtm for Sales Reps. We don’t believe AI is going to replace people in GTM, we believe its going to make them 100x more effective 🧵

I'm thrilled to share our latest collaboration with OpenAI The Unify Observation Model: a generalized framework / system to get deep, realtime knowledge of companies in your TAM Read more about it at the link below on OpenAI’s blog post
