OrgOrg

Organizational productivity suite for companies

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.

Origami Therapeutics, Inc. logo

Origami Therapeutics, Inc.

Oral drugs to halt neurodegeneration

Origami Therapeutics, Inc. is a biotech company developing novel protein degraders with potential to delay or halt disease progression by eliminating toxic proteins from the body. Our drug discovery platform leverages our proprietary human disease models developed to select the small molecules with the best chance of clinical success. Our first indication is Huntington’s disease, a debilitating, progressive and ultimately fatal disorder caused by a genetic mutation. We have already identified small molecules that reduce the toxic mutated protein, suppress mutant protein-induced toxicities in human disease neurons and get into the brain. We anticipate that this approach will be broadly applicable to traditionally “undruggable” targets in other neurological diseases.

Origin

Keurig for healthy smoothies.

Origin built a kiosk for offices that lets employees buy pre-packed pods from a freezer, and make them into fresh juice smoothies silently in 30 seconds. It works similar to a Keurig coffee machine, but Origin thinks it can use its smoothie maker as a Trojan horse to sell more food and other items inside the 188,000 offices in the US. Right now it earns a 56% margin on the $2.99 pods, recoups the kiosk cost in 7 weeks, and now has $30,000 in monthly recurring revenue as it grows 50% weekly. Fellow juice maker startup Juicero has run into slow demand for its expensive machine and juice subscriptions. But Origin’s in-office commerce model and cheaper pods could have a different fate if the juice tastes right.

Osmind logo

Osmind

Platform for breakthrough mental health research and treatment

Osmind is the premier platform for clinicians and researchers advancing new life-saving mental health treatments. Today, mental health disorders are one of the leading causes of death worldwide, especially among young adults, and are tied to shortening lifespans. While there have been developments in new psychiatric medications since the first FDA approval in 1954, today there is a growing movement among clinicians, patients, and researchers who are recognizing the need to accelerate new science. The Osmind treatment platform is the first and only solution that solves specific challenges faced by neuropsychiatric clinics, spanning general psychiatry and interventional psychiatry (transcranial magnetic stimulation, ketamine, SPRAVATO®, psychedelic medicine, electroconvulsive therapy). The core electronic health record (EHR) technology is precisely developed for interventional treatment workflows and designed to support a strong therapeutic alliance, including journaling tools and assistance with health plan reimbursement, which is a significant access hurdle for millions of patients. Research from our platform is already helping to set new standards for mental health interventions. For example, in the largest published real-world analysis of ketamine infusion therapy for depression, we teamed up with Stanford University School of Medicine to share findings in the Journal of Affective Disorders (March 2022). We have multiple ongoing research studies leveraging our proprietary real-world data, including an even larger ketamine analysis leveraging machine learning to predict treatment outcomes. Osmind is a San Francisco–based public benefit corporation led by scientists, technologists, and psychiatrists. We are backed by top investors including DFJ Growth, General Catalyst, Future Ventures, Tiger Global, and Y Combinator.
