So many creators lose their unique soul to become something that the masses are willing to give a like to. If you will follow a viral content playbook, please follow the one that will honor your story, your intention, and heart. You've got this. I love you.

@bondwithchloe let's goo

Re-introducing...Bond, your AI Chief of Staff. You worked 10 hours yesterday. Maybe 2 of them actually mattered. The rest? Standups, Slack threads, status updates, triaging emails. Executives don't need to work harder. They need Bond 👉 bondapp.io

@ycombinator @Heypocket @AkshayNarisetti @gabrieldymowski @AkshayNarisetti vamoooos

Pocket (@heypocket) is your notetaker for real world meetings. In the last 5 months, the team has delivered over 30k units with a $27M annualized run rate, growing 50% month over month. Congrats on the launch, @AkshayNarisetti and @gabrieldymowski! ycombinator.com/launches/PaX-p…

How could we let this happen? To quote Klaus Schwab, Founder of the World Economic Forum, on the impact of cyber security across our societies, economies, and geopolitical landscape: "The COVID-19 crisis would be seen in this respect as a small disturbance in comparison to a major cyber attack." "[...], which would bring to a complete halt to the power supply, transportation, hospital services, our society as a whole!"

NOW HIRING: Engineers that want to work on something impactful. Over the last year, we have been collaborating with multiple Fortune 500 CISOs, some of the world’s largest defense contractors, and other globally recognized organizations. All the while being backed by multiple Tier-1 VC firms here in Silicon Valley. If you want to help protect our societies, economies, and geopolitical landscape against a rapidly growing set of global threat actors, we want to hear from you. The world we know is no longer the same: Technology does not turn off when you close your laptop or turn off your phone.

Tech Founders in Latin America 👀 Here’s why you should apply to @ycombinator today (maybe not the reasons you think) 🌎 Deadline for the next batch is tomorrow, Tuesday 13th 🤷🏻‍♀️ I recommend you follow @garrytan for updates. Here’s YC’s request for startups: lnkd.in/eg_bQRwF (that site not super friendly haha my friends are building a friendlier version of Calls for Startups that will be launched soon, stay tuned)

@felixleezd @ycombinator Let's gooo, add me pls :)

Designers, YC is calling for you. @ycombinator just put out a "request for startups" for more designer founders. starting a group chat for designers who want to build their idea/startup... we’ll share: - product ideas - best frameworks and tools - design engineering talks - design founder chats reply if you wanna join

@SimoneAngelov @theresidency let's build it :)

@Honestbubble @theresidency Wish there was like a list of houses and women giving their reviews

For women in tech: I wanted to share my experience living in hacker houses / founder houses (like @theresidency). In the video I also share what it’s been like navigating events, solo travel, and other parts of the ecosystem as a woman. Love you. May you continue building amazing stuff surrounded by amazing people.

@iamethanglenny @theresidency that's the actual prize

@Honestbubble @theresidency Love being surrounded by such amazing humans that make everyone feel safe and seen

@michellewang857 DM me :) Woman in tech here in SF.

@sora from @OpenAI is giving me the "no videos for new accounts" notification - what's a better tool to use if I wanna generate a video? 👀 Thanks, love you.
