I just published “My Mother’s Greatest Gift” medium.com/p/my-mothers-grea…
As @btaylor & @claybavor say: “We have never had such conviction in the opportunity for @SierraPlatform and our customers."
And I have never had such conviction that now is the best time to join Sierra.
The momentum has just begun... 🚀
Sierra is raising $950 million from new and existing investors, led by Tiger Global and GV, at a valuation of over $15 billion. We now have more than $1 billion to invest in becoming the global standard for companies wanting to transform their customer experiences with AI.
We’ve never had such conviction in the opportunity for Sierra and our customers. Just a couple of years ago, we had four design partners. Now, Sierra is serving over 40% of the Fortune 50, and agents built on our platform are powering billions of customer interactions — everything from refinancing homes to processing insurance claims, returning orders, and helping people raise millions in fundraisers.
We’re deeply grateful to our customers for helping show what’s possible. If you’re not yet using Sierra, we’d love to partner with you. sierra.ai/blog/better-custom…
Join us!
From Singapore to Spain - Sierra is hiring. If you're excited to work in a low ego, high intensity culture and motivated by the idea of having an unreasonable amount of responsibility ... check out our careers page: sierra.ai/careers.

After Sierra reached $100M in ARR in seven quarters, we followed with our first-ever $50M quarter — kicking off our third year with over $150M in ARR. @claybavor
and I so grateful to every customer who partnered with us this year sierra.ai/blog/year-two-in-r…
You can't charge there! Rivian crashed into building in Lafayette, CA. Looks like everyone is okay 🙏 @nbcbayarea @abc7newsbayarea @KTVU @KPIXtv @kron4news @KiraKlapper
Love this so much! Shout out to the Keepers of the Alphorn, Kevin Crain and Andrew Timmons, as well as Creative Director, Mari Ju! (And some pretty awesome photography from a pretty awesome photographer, I must say... 😉)
“If you’re excited about our speed and direction of travel, come and join us — we’re hiring. As one Sierra team member put it: ‘This is the hardest I've ever worked, and the most fun I've ever had.’”
Sierra just hit $100M in ARR, just seven quarters since we launched in February 2024. @claybavor and I are very grateful to our customers and proud of the Sierra team, who has redefined the meaning of intensity and craftsmanship. I have never had this much fun in my career. (Photo is Clay signing the contract that crossed the $100M mark) sierra.ai/blog/100m-arr

StegoBARTus? Spotted on @SFBART this morning. Do they have a Clipper card?

#1 way to grow as a business…listen to every episode from @lennysan at least twice. Guests and his interviewing style are a builder’s grad school.
The line about “anecdata” is worth a million saved mistakes. Freakin brilliant @btaylor 🙏

Sierra is growing fast, and we need a strong agent development team to support all our new customers. This team is where the theory of LLMs meets reality. And whether you're joining as an agent software engineer or product manager, these are much broader than traditional roles in these fields, with many, many opportunities to learn. Our agent software engineers, for example, are deeply involved in our customers' businesses. Depending on the partner, your day to day might involve understanding mortgages and how people apply for them, the drivers of churn in a subscription business or the complexities of a specific piece of hardware. Think engineering meets business development. And on the product side, you'll be stretched technically in ways that's often not possible at other companies—coding agents, helping customers navigate their different information systems and much more. We're hiring. Come and help us build the future here in NY.
“They’re also hiring…” DM me with interest!
🆕 One of the most successful agent companies in the world is @SierraPlatform, cofounded by @btaylor who happens to be Chairman of @OpenAI. But they've been relatively stealthy about *how* they build and operate....
until now.

We're honored for @ZackRW to pull back the curtain on Sierra's Agent SDLC - or ADLC - for the first time ever!
They're also hiring - at the last World's Fair a chance convo with an attendee led to a fantastic new hire - so talk to Zack for more! even if you're not looking for a job, @sierraplatform is worth a follow on X :)
