  • Opentrons
    Opentrons (W16)Active • 300 employees • New York
    Today, biologists spend too much time pipetting by hand. We think biologists should have robots to do pipetting for them. People doing science should be free of tedious benchwork and repetitive stress injuries. They should be able to spend their time designing experiments and analyzing data. That's why we started Opentrons. We make robots for biologists. Our mission is to provide the scientific community with a common platform to easily share protocols and reproduce each other's results. Our robots automate experiments that would otherwise be done by hand, allowing our community to spend more time pursuing answers to some of the 21st century’s most important questions.

  • Vanta
    Vanta (W18)Active • 330 employees • San Francisco
    Vanta was founded in 2018, in the wake of several high-profile data breaches that shook our collective faith in internet businesses. Online security was only becoming more important, but we knew firsthand how hard it could be for fast-growing companies to invest the time and manpower it takes to build a solid security foundation. From our early days of automating security monitoring for compliance standards like SOC 2, HIPAA, and ISO 27001, to pioneering a brand-new market as the leading Trust Management Platform, our vision to restore trust in internet businesses by enabling companies to improve and prove their security remains unchanged. Now more than ever, making security continuous—not just a point-in-time check— is essential. Vanta is the leading Trust Management Platform that helps simplify and centralize security for organizations of all sizes. Over 4,000 companies including Autodesk, Chili Piper, Flo Health and Quora, rely on Vanta to build, maintain and demonstrate their trust—all in a way that's real-time and transparent. Recently named the #1 Leader in G2's Winter 2023 Grid® Reports for Security Compliance, Vanta debuted a number of new product innovations over the last year, including Access Reviews which automates the once-manual, time-consuming access reviews process and an enhanced Risk Management solution allowing companies to holistically understand, prioritize, and reduce risks within their company to build a stronger security approach and demonstrate compliance. Vanta was built on the idea that software can be used to do amazing things for the world—if we trust it to do so. And we can’t do it alone. Come join us!

  • Delphia
    Delphia (W18)Active • 35 employees • Toronto, Canada
    [Delphia](https://delphia.com/) is building a new kind of asset manager that rethinks the value of data and how it can be used to gain an edge in forecasting markets. We believe that actively managing people’s data can unlock new forms of wealth creation for individual and institutional investors alike. To create the next [Millennium](https://www.mlp.com/) (and eventually, [Blackstone](https://www.blackstone.com/)), you need each of the following; 1. A captivating reason for people to connect their data ([in beta](https://abr.ge/k4xqep)) 2. A way to automate data extraction from aggregators ([acquired](https://www.prnewswire.com/news-releases/delphia-strengthens-data-rights-with-acquisition-of-fathom-privacy-301696745.html)) 3. A cooperative way to ensure "fair trade" compensation for data ([built](https://www.supersetdao.com/)) 4. A way to reward data contributors transparently and irreversibly ([on pause](https://www.coindesk.com/business/2022/09/28/algorithmic-stock-platform-delphia-debuts-digital-asset-component/)) 5. A way to discover investment managers with uncorrelated alpha ([open sourced](https://github.com/charliereese/investos)) 6. A way to help investment managers make use of our data advantage ([partnered](https://covariance.ai/)) 7. A way to access to stock order flow that has net benefit to retail investors (coming soon) 8. Capacity rights in investment strategies whose returns improve with data ([first of many](http://www.oraclealpha.com/)), and 9. A secure training environment for third-party ML models (the goal of our next venture round) If our thesis bears out, the $7 billion alternative data industry ([$135 billion by 2030](https://explodingtopics.com/blog/alternative-data-market)) may be in for a Cambrian explosion that has yet to be priced in. Being able to acquire ground truth cost-effectively using first-party data, and thus being able to forecast fundamentals more accurately, is the key to attracting the world's best investment ideas to a platform. People at Delphia are socially-minded creatives at heart. Our teams are continually researching, iterating, and solving hard problems in order to generate new forms of economic returns. Our multi-disciplinary team was founded in 2018 and is a graduate of [Y Combinator](https://ycombinator.com/) and the [Creative Destruction Lab](https://creativedestructionlab.com/). We’ve raised three rounds of funding ([~$80 million](https://www.crunchbase.com/organization/delphia)) to date.

  • Ophelia
    Ophelia (W20)Active • 130 employees • New York
    Ophelia helps people quit opioids without going to rehab. We offer online doctor’s visits, withdrawal medication prescriptions, and support for long-term recovery, using a protocol 6x more effective than most rehabs (2/3rds of which don't have doctors). More than 3 million Americans are addicted to opioids, but 80% are not getting help, due to jobs, families, and privacy concerns. Meanwhile, there's a proven treatment that increases survival rates by 600%, and it's low cost, discreet, and convenient. It's called MAT, and it looks like treatment for anxiety or depression: medication plus therapy. However, doctors need a special waiver to prescribe the medication, which fewer than 5% of them have, so it's difficult to get, and most people are buying it on the street. Sadly, drug dealers aren't doctors: every 11 minutes another American dies of an opioid overdose, now the #1 cause of death for Americans under 50. Ophelia is replacing rehab with telemedicine, using proven science and a consumer-first approach. The opioid treatment market in the U.S. is $15B, and 85% of opioid addicts have insurance that pays for it. We're treating roughly 400 patients with thousands more waiting. Zack started Ophelia after losing his girlfriend to an opioid overdose, who found it easier to get medication from a drug dealer than a doctor. We are raising money to help patients in waiting, grow our footprint, save lives, and earn venture-level returns for investors.

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

    JumpWire is a software platform for enforcing data security between APIs, applications and databases. By referencing data schemas, JumpWire labels select properties inside data payloads and transforms the raw data into a protected format, using encryption, tokenization or masking. JumpWire’s approach to securing data in-place minimizes the risk of data leaks exposing sensitive information or mishandling by other applications and vendors. The exact security scheme applied to data is defined by policies that align with an organization’s existing InfoSec program. JumpWire helps companies who maintain information security with compliance programs such as SOC or HIPAA. They are processing sensitive data, often from their own customers, and exceed security best practices as a competitive advantage. JumpWire provides defense at depth to data and sits alongside access controls and Layer 4 encryption to provide a comprehensive data security solution. JumpWire is unique from solutions such as data vaults by installing inside our customers’ own infrastructure and clouds. It is interoperable with existing applications and databases, which eliminates the need for large data migrations or code refactoring. Lower-level approaches to data security, such as encryption at rest, are too blunt and lack the ability to differentiate between properties in the data itself. Its scope is limited to physical storage, and security is lost as soon as an application or query loads the data.
