When a VC says they want to pre-empt your round and then asks you to come into a partner meeting and talk to a bunch of customers, they’re not actually asking to pre-empt; they’re asking you to run a fundraising process with one potential bidder.
Quarterback Goals this Season: Patrick Mahomes: Win a SB Joe Burrow: Win a SB Lamar Jackson: Win a SB Josh Allen: Win a SB Jalen Hurts: Win a SB but don’t hand the ball off to Saquon Barkley too much, make sure the defense isn’t too good, and produce the best individual stats

1/ We've raised $8.6M led by @firstround to kill all back-office work for startups 👇 Here's why:
Founders sometimes forget that their current round pricing can really affect their next round.
The hardest thing in venture is reinvention. You’d think success should naturally lead to more success, but more often, it traps you. Success makes investors complacent, convinced they’ve “found the winning formula.” But the truth is, consistent great returns only come from…
Some tools charge $35/month to stop training their models on your private notes. At @NotionHQ, your data isn’t used for model training by default, on any plan (even free!)
We've developed a system — the Roblox Operating System — for creating innovative solutions and bringing them to market quickly. In his new book, Keith Lucas shares early stories and lessons as we were developing these norms keithvlucas.com/writing/impact/
AI-generated videos are flooding our feeds. While the tech is mind-blowing, there are some serious hurdles to most users actually making great ones themselves. Most AI video tools are either wildly complicated or “one-click” magic (aka zero control). They make one scene at a…

So for 5 years, “offline” has been the #1 request. Today, thanks to the perseverance of our engineering team, @NotionHQ finally works offline. Your ideas don’t need Wi‑Fi to exist! For Notion community: thank you for your patience while we built this right. This is a journey,…
📍Times Square! Thank you, @Nasdaq , for spotlighting our Series A. We’re grateful for the partnership to bring the first growth-oriented exchange fund to market. Historically, exchange funds were built around broad market indices. But to create one, you need stocks from every…
📍 We've just dropped our pin: in San Francisco! 🌉 Our 2nd office will be in the bay area and we're hiring! Want to hang with the team IRL and build great stuff while doing it? Apply for our open roles (in SF) here! clay.com/jobs
🚀 We’ve raised a $12.5M Series A at a $125M valuation. We’re solving a problem hiding in plain sight: overconcentration in company stock. We understand – selling means a massive tax bill. But, holding means massive risk. Cache has shown there’s a smarter way! Cache Exchange…
Announcing our $70M Series B co-led by @stripe and Addition, and with participation from @usv, @firstround, @BloombergBeta, @BoxGroup, @RibbitCapital, and other top investors. We also recently shipped two AI-native tools: Stedi Agent and MCP server. For more, check below. ⬇️
