OrgOrg is a suite of apps that keeps teams productive and healthy regardless of the size of your organization. Founded by the creator of Zenter (YC 07, acquired by Google and became Google Slides), OrgOrg is designed to be a natural extension of Google Workspace Apps to help run organizations collaborate better leading to higher productivity. Today the suite includes apps like: • Go links: Go links allows anyone in the org to easily name any link so team members can jump directly to the information that matters most: go/sales, go/production, go/anything-you-want. • Profiles with Personality: OrgOrg profiles are as insightful as they are delightful. They not only show you the expected org chart data, but also highlight accomplishments, how you like to work, and who you are as a person. • Goal tracking: Track, share, and collaborate on "big rock" goals on the cadence that makes sense for your team from daily to annually. • Branded New Tab: Keep the team focused the next major milestone, broadcast announcements, and keep important links top of mind every time a new browser tab is opened. • All Hands Q&A: Crowdsource questions, anonymously if desired, for large team meetings to make sure everyone's voice is heard, and the most top of mind questions are answered and recorded. • Smart Groups: Create rules based groups of people and use them to make sure the right people are in the right conversations and have the right access. For example, anyone with the title of "Software Engineer" should be in the #eng slack channel and eng@ google group. • On-call: Schedule smart rotations that take into account balancing the load and using signals from calendar schedules to make sure you don't waste time figuring out who can cover what in a fair way. Easily page the on-call from slack, API, or OrgOrg directly. • And more... All the tools you need so you can spend more time focusing on your core business, and less time focusing on the complexity that comes from running an organization.

Modern teams work in the browser. But browsers weren't built for teams 😔. This leads to a bunch of problems like: - Knowledge/info that is hard to find (links that get lost, documentation that gets, buried, silos, etc) - Poor collaboration - Inefficient workflows LinkGrep is an AI browser copilot that solves those problems by making your browser team friendly. Specifically we help teams: 1. 🔗 Keep track of links, documents, and more automatically. With LinkGrep you'll never have to manually add or save a link. 2. 🔍 Find information that matters. LinkGrep connects with your existing tools like Notion and Slack and will automatically suggest relevant information to you as your browse (we have semantic search that you can fallback on). Demo: https://youtu.be/jwcPGDRy4oQ 3. 👥 Collaborate better. LinkGrep lets you leave notes and comments directly on web pages — you won't ever have to copy paste a link into Slack ever again. 4. 🤖 Automate team actions like opening up the right links before a meeting. Never disrupt a meeting to send a link again. Demo: https://youtu.be/an3VKpAWft0

Dailybot is the coordination platform for software teams where people and AI agents work side by side. As engineering teams increasingly operate alongside multiple AI agents — coding agents, incident responders, research assistants — the gap between what's being worked on and what the team can actually see has become a critical problem. Dailybot closes that gap. Teams use Dailybot to run async standups, check-ins, retros, and custom workflows directly inside Slack, Microsoft Teams, Google Chat, and Discord. In Dailybot 3, those capabilities now extend to AI agents: every agent can report progress, surface blockers, and be monitored in a dedicated observability layer — all attributed to the humans who delegated the work. The platform combines four capabilities: structured check-ins and forms in chat, AI-powered summaries and blocker detection, no-code workflow automation, and agent infrastructure (API, CLI, open-source skill pack, fleet monitoring). Leaders get a proactive view of what people and agents accomplished together — without adding meetings or dashboards to check. Dailybot is SOC 2 and GDPR compliant, backed by Y Combinator (S21), and trusted by teams at IBM, Samsung, Pixar, and 8,000+ teams worldwide.

UpLink's founding team worked as auditors and software engineers at PwC where they saw firsthand how difficult it was to collect thousands of documents from clients. Alex Maher and Alex Grant met working on PwC’s big data analytics platform, scaling it from 0 to 20k users globally. Brady and Nick met while studying CS at a top 5 public university, but still insist they were self-taught. They were, by far, the top developers on Alex Maher’s team before starting UpLink. Together they ran Dycom's field systems segment, supporting 15k users.

WorkLife is a web app that helps teams have more productive meetings. There are over 3 Billion meetings/year in the U.S. and studies show 50% of that time is completely wasted. WorkLife helps you reclaim that time by helping you and your team adopt good meeting habits - create agendas, stay on track during the meeting, and ensure next steps get done afterwards. Most people spend the majority of their waking hours at work, and way too many of those hours in unproductive meetings. Your work life is a big portion of your life -- and the happier and more productive you are at work, the more fulfilled and energized you are in your life. Better Work = Better Life.
