Incredible community, unmatched team. Do not sleep on this deadline! 💯
hey all - update for SR008:
It's now the FINAL weekend to apply for our next residency in San Francisco. Applications close this Sunday, Nov 1 at 11:59 PM PT.
Here's the link:
speedrun.a16z.com/apply
How it works:
- you apply
- we review, reach out to get introduced, etc
- if there's a fit, we handshake and sign
- we wire our investment right away!
- plus you get access to >$10M in credits right away
- you'll onboard + start working with us immediately, have access to working out of our SF offices, etc
The official residency starts Feb 2027 where we'll have speakers, office hours, and much more. I plan to be on site and look forward to meeting many of you
You might ask- who's the best fit for this? We want to talk to you as early as possible, and that means:
- no company yet
- no deck
- no huge insight tweet thread
- sometimes not even fully committed yet
You don't need the perfect idea. We can start working together when you're iterating and getting the idea off the ground. That's the whole point of speedrun - it's our way of backing you from Day 0.
More official stuff below:
- Deadline is this Sunday, Nov 1 at 11:59 PM PT (this weekend!)
- SR008 runs Feb 1 through April 18, 2027 in San Francisco -- twelve weeks of firesides, office hours, and sessions, closing out with Demo Day on April 13 in front of thousands of investors
- Capital: up to $1M with a two-week close target, plus $10M+ in credits from 200+ partners
- Customers: SR Insiders gets you in front of 10,000+ buyers and operators, including 150+ C-suite execs, plus a full day of live demos at AI Faire
- Talent: our Talent Network of 171,000+ engineers, designers, and product people. 230+ hires so far, $0 in fees. Plus visa, banking, and housing help if you're coming from abroad
- A team of ~40 battle-tested investors and operators who help cover your gaps without adding headcount -- GTM, marketing, brand, talent, fundraising, and more
- a16z speedrun is super selective -- fewer than 0.4% of applicants get in. You'll join a tight-knit community of founders from 20+ countries who stay involved as speakers, advisors, and often each other's first customers
- Still in school or still finding your idea/team? Check out the alpha fellowship too -- up to $250K for students, recent grads, and dropouts

Pretty cool way to start the day.
@a16z featured @siriusai in their latest roundup of breakout startups hiring, with @benaziration and me on the cover.
We’ve grown a lot over the past year, and we’re continuing to build out the team in San Francisco.
Right now, we’re hiring a Founding Events & Partnerships Lead to help us with the next stage of Sirius.
A lot more to come.
Thanks to the @a16z team for the feature, and if you’re interested in joining us, reach out!
super excited to announce that @benaziration and I will be presenting @siriusai at a16z Speedrun's invite-only AI Faire during SF Tech Week on October 9!
our @siriusai team will be there as well. excited to meet everyone coming out and see some of the best B2B AI companies across @speedrun all in one place.
DM me if you want an invite!
quick @siriusai update:
in the last 4 weeks, we’ve helped our customers keep 336K+ customers and $11M in retained revenue.
the biggest thing we keep seeing is that retention works way better when every customer isn’t treated the same.
different people leave for different reasons.
the save experience should reflect that.
this is exactly what we’re building @siriusai around.
SF is one of the only places where you can go to dinner with no agenda and leave with a customer intro, a candidate, and three completely new ideas. What city comes closest?

Acquisition gets all the glory because it is easy to see. Retention is quieter, but it tells you whether people actually wanted what you built. Which one would you rather be world-class at?

I think founders overvalue being right and undervalue changing their mind quickly. The people I respect most can defend an idea hard on Monday and kill it on Wednesday when the data changes.

Hot take: if your startup needs 6 meetings to decide whether to test something, you are already operating like a big company without any of the advantages.

We’re building out Growth at @siriusai and looking for someone who wants a lot of ownership from day one.
If you’re creative, deeply online, move fast, and want to help make Sirius impossible to ignore, take a look.
We’re hiring for Growth at @siriusai in SF.
We’re growing fast, backed by a16z @speedrun, and looking for someone who wants real ownership across content, distribution, partnerships, launches, events, experiments, and new growth channels.
You’ll work closely with the founding team, move fast, test ideas, and own projects end to end.
The goal is simple: we want Sirius everywhere.
Competitive salary + equity, free daily lunch, coffee, snacks, flexible PTO, and a lot of ownership.
Full-time, in person in San Francisco.
If you think you’d crush this, comment “Sirius” or email me at [email protected]

The customer feedback that changes the product is usually not “this is great.” It’s “I almost stopped using this because…” Those are the conversations I want more of.

Poker is one of the few places where you can make the right decision and still lose. Probably why founders like it so much.

One of the clearest examples of what we’re building at @siriusai is @promova_app.
Within four months of using Sirius, they had automated roughly 60% of their retention operations. By the one-year mark, that number was above 90%.
The interesting part wasn’t just automating more work. It was making better decisions at the exact moment a customer was about to leave.
Not every customer churns for the same reason, so treating every cancellation the same never made much sense to us.
@promova_app is a great example of what happens when retention becomes more intelligent, personalized, and operational at scale.
