I started writing about company-building frameworks and principles about 18 months ago to share with Team @Sequoia. I'm now sharing them more widely in the hope that they provide you with the provocation to get better at getting better. Learn more at

.@Kalshi is on one of the most impressive trajectories we have ever seen @sequoia. @mansourtarek_ & @luanalopeslara have assembled a team that uniquely blends Silicon Valley and Wall Street talent with the ambition and execution to fundamentally transform financial markets.
I’m excited to announce our $185M Series C valuing Kalshi at $2B. The round was led by Paradigm with participation from Sequoia, Multicoin, Peng Zhao, Neo, and Bond Capital. People choose to work at Kalshi not because of the money we've raised, but because of our ambition:

For high-growth startups, every minute shaved off contract negotiations = faster revenue. @crosbylegal combines AI’s speed & intelligence with the safety of lawyers to review contracts in under an hour. Proud to partner with @Ryanjdaniels & @jsarihan .
Today we’re introducing Crosby, a hybrid AI law firm that helps rapidly growing businesses execute faster. Contracts are connection points. They allow companies to transact with one another and create economic growth. But while every aspect of business has sped up, the way we.

Long development cycles have become cripling, and testing has become a chokepoint for hardware engineers. Thanks to @CameronLMcCord, @jrshoch, @brycestrauss, and their team at @Nominal_io for bringing hardware into the modern age of agile development. We are proud to be their.

1/ Today, we're proud to announce that Stripe is acquiring Privy. We couldn’t be more excited. Privy will continue as an independent product – but now we’ll move faster, ship more, and serve you even better, so you can stay focused on your users.

Congrats to @sadbryce, @whojackjones, and the @turnkeyhq team on the Series B!. @turnkeyhq powers millions of wallets and transactions weekly with secure, programmable infrastructure. The future of crypto is non-custodial, user-friendly, and built on open systems.
1/ We’ve raised a $30M Series B led by @BainCapCrypto to build the open infrastructure that powers crypto’s next era. This is a major moment for @turnkeyhq. For our team, our customers, and the entire space.

CFOs are under pressure to capture the potential of AI. But the general ledger was still stuck in the past, until @NicCKopp, @StelMod, and the @RilletHQ team came along. We @Sequoia are excited to support them and lead their Series A.
Announcing our $25M Series A led by @sequoia . Ten months ago, we came out of stealth to rebuild the general ledger from the ground up with AI at the core. Today, we power the finance stack behind some of the fastest-growing companies like @windsurf_ai and Decagon. Why are we.

The best companies invest in their people. @kareemamin & @vxanand are allowing employees to monetize some of their equity on their timelines. @clay_gtm has become the essential data engine for modern GTM teams and is only getting started. Excited to deepen our partnership.
Today, we're announcing a tender offer led by @sequoia at a $1.5B valuation, giving Clay employees the option to sell some of their vested shares for immediate liquidity. This is an increase from our $1.25B valuation announced 4 months ago. Startups are a long journey and teams

.@Kalshi launched sports markets in January 2025. The results come from intense execution, superior product experience, and strong partnerships.
The 2 book hierarchy is being overthrown as we speak. Insane volume by @Kalshi who has only been in the space a few months. The Robinhood mesh brings retail liquidity to all 50 states & should make for an exciting future for bettors

.@mwseibel - you've had an incredible impact on countless founders and helped so many companies get started. Thank you for everything you've done for the startup ecosystem. Excited to see what you do next.
Today after 12+ years at Y Combinator I’ll be transitioning to a Partner Emeritus position. This role allows me to continue to do office hours with the 1000+ companies I’ve worked with in the past decade while giving me the free time to explore new adventures. It also means.

A decade ago, Robinhood pioneered commission-free trading and took stock ownership mainstream. A year ago, Kalshi defined a new asset class and brought prediction markets to critical mass. Today, we at Sequoia are proud to see these two category-defining companies partner to.
Lior, Rainer, Noah, and team were up till 4:20am working to get every single march madness game listed after Selection Sunday. The Robinhood engineering team was working in lockstep with up to ensure a smooth launch at market open. We did it with elections and now we will do.

Ask your doctor if they use @EvidenceOpen. If not, it might be time to get another doctor. Better yet, use it yourself and be informed than your doctor. 🤣.
Doctors are using @EvidenceOpen millions of times every month to make better decisions at the point of care. This may be the fastest any technology product (outside of the iPhone) has been embraced by the healthcare industry. and this is only the beginning.

7/ If you’re an early-stage founder, another pathway to @Sequoia starts with an Arc application. Could your story be next?. Applications close on February 23rd.

6/ @Keller noted two @Zipline alums to keep an eye on: @bennbuilds and @4TristanS. Their viral video caught our attention & their vision to sell sunlight to solar farms after dark was too intriguing to ignore. @Sequoia led @reflectorbital’s seed last year.

5/ @zoink introduced @andrew__reed & @christinacaci via email. Andrew knew that if Dylan made an intro without a double-opt-in, then Christina was special. After one hike and rapid diligence over a few days, @Sequoia led @TrustVanta’s Series A.
