  • imgix
    imgix (s2011)Active • 65 employees • San Francisco, CA, USA
    Nobody should have to employ expensive imaging scientists and engineers for their business to get the most out of their visual media. This is where imgix has your back. imgix is a platform for managing, processing, rendering, optimizing, and delivering your existing visual assets so that you can meet the demands of your business and your team can stay focused on what they do best. The business demands on web visual media can blindside even the most hyper-aware content teams and developers. Just to be competitive on the Internet, you need your images to be sized perfectly to every device, served in one of any of a half dozen web formats, optimized to the absolute best perceptual quality while maintaining pinpoint performance, and distributed to wherever your users are, anywhere in the world. And that is just the baseline. Next-level imaging concerns like copyright, licensing, accessibility, moderation, illegal or explicit content, "fake news", and more, can threaten your business at any moment if not handled properly. Get any of these things wrong and you are shedding revenue, ceding ground to competitors, and potentially exposing your business to extreme liability. By working with imgix's powerful APIs, SDKs, user interfaces, and integrations, you can rest assured that any demands on your images and videos will always be met, now and into the future, without you having to invest in building it yourself or patching together a mishmash of open source and third-party technologies. Our platform is designed to ensure that your images are always working for your business and never against it. imgix was launched through the famed Y Combinator accelerator program. Its customers include Google, Lyft, Kickstarter, AirBnb, Coursera, Bonobos, Spotify, Vimeo, Bustle, and many others.

    Sieve is a specialized cloud built for video / audio AI. Every video product today is being overwhelmed by a ton of new use cases that are enabled by AI. Video is unique in that it’s much more compute and data-intensive to process or generate compared to other modalities. This leads to a ton of complexity around the ways models are run, the kinds of extra processing needed to happen around them, and the complexity of pipelines that solve the most valuable use cases in the modality. To this end, Sieve’s strongest and most immediate value proposition comes from being an AI toolkit that solves problems unique to video — unlike generic AI developer tools that might exist today. Video is just the start however. Learn more about our long term vision [here](https://sievedata.com/about/jobs)!

    Mezmo, formerly LogDNA, is an observability platform to manage and take action on your data. It ingests, processes, and routes log data to fuel enterprise-level application development and delivery, security, and compliance use cases. Mezmo was brought to life by three-time co-founders Chris Nguyen and Lee Liu and included in the Winter 2015 batch of Y Combinator. In 2018 the company partnered with tech giant, IBM, to become the sole logging provider for IBM Cloud. Mezmo is on a mission to empower people who build solutions that shape the world. We’re doing this by delivering a platform that enables enterprises to get more value from their observability data in real time, regardless of source, destination, use case, or scale. We’re not the only ones working on this problem but we have a few things the others don’t. We’re cloud-native and know how to make the most of modern technology like Kubernetes. We have scaled a solution from zero to petabyte scale in a short amount of time, while supporting thousands of active users across multiple environments. We are hungry for change and are surrounded by enterprises telling us they’re hungry, too. We have a kick-ass group of people who are thinking about the problem analytically and are excited to change the observability world for the better. Mezmo has helped some of the world’s most innovative companies transform how they manage their systems and applications. Still, we know that we can help them get more value from their observability data by providing more flexibility and control over how they use it. This will enable teams to spend less time switching between data silos so they can focus on shipping better, more resilient, and secure products. We have momentum on our side. Last year we saw triple digit revenue growth and added 800 new customers to our roster. Recent accolades include being named to YC’s Top Companies, CRN’s 10 Hottest DevOps Startups, and EMA’s Top 3 Observability Platforms.

IPFS is one of the leading protocols of Web3, crypto, and the decentralized web movements. IPFS serves millions of end users and tens of thousands of developers. It powers the websites and applications of small startups, large enterprises, and even blockchains. Filecoin is a decentralized storage network, designed to store humanity's most important information. Filecoin is a cryptocurrency incentivized decentralized market, where storage providers earn filecoin tokens for renting out storage space. (Think airbnb for cloud storage). Filecoin is one of the leading projects in the cryptocurrency/blockchain space.

    Aquarium Learning (s2020)Acquired • 12 employees • San Francisco, CA, USA
    ML models are only as good as the datasets they're trained on, and that means that most improvement to model performance comes from improvement to the quality and diversity of their datasets. Our tooling makes it easy for ML teams to find anomalies + failure patterns in their datasets and fix these problems by editing / adding the right data. So the next time you retrain your model, it just gets better.

  • Satsuma
    Satsuma (s2021)Acquired • 5 employees • San Francisco, CA, USA
    Satsuma is a developer tool for building applications on top of real-time blockchain data. Our product lets developers take decoded data from multiple chains, customize it for their use cases, and access it through API endpoints. Blockchains serve as distributed databases for these products, holding their most important data. However, it’s difficult to access and query that data. We believe this friction is an enormous blocker for web3 developers and that better tooling will enable mass adoption for web3. We’re a founding team of engineers, having built data infrastructure and product as early employees at Airtable, Heap, and Y Combinator.

    Nestybox creates software that enables Linux containers to act like virtual machines. This increases the use cases for containers and gives enterprises a less expensive and more flexible alternative to virtual machines in many scenarios. Our first product is a "container runtime", the software that creates the containers. It's called "Sysbox" and integrates with the popular Docker and Kubernetes engines, enabling these tools to deploy containers that act like virtual machines. This technology provides software engineers with an alternative to VMs, one that easier to use, much more efficiency, and easily migrated across clouds.

  • Peer5
    Peer5 (w2017)Acquired • 11 employees • Palo Alto, CA, USA
    Peer5's P2P CDN improves content delivery for live and on demand video streams. As video streaming continues to become more mainstream and the streams themselves become HD and 4K, traditional CDNs struggle to deliver high quality viewing experiences. Many publishers try to keep up with peak demand by paying for more servers, many of which are almost never used and struggle with video playback. Not only is this expensive, but it's also inefficient, which is why at Peer5, we've created a P2P CDN to boost your video streaming capabilities. Our CDN works with your servers to ensure that as your viewership increases, your network gets stronger by offloading bandwidth to our peer network. On average, this has been shown to increase server capacity by 20x, offload 70% of bandwidth, increase viewing time by 30% and decrease instances of rebuffering by 40%. Our video streaming CDN uses emerging technologies, including HTML5 and WebRTC. They require no installation by end users and offer easy integration for content providers. We support many different streaming protocols, players and media servers.
