Dropbox is building the world’s first smart workspace. Back in 2007, making work better for people meant designing a simpler way to keep files in sync. Today, it means designing products that reduce busywork so you can focus on the work that matters. Most “productivity tools” get in your way. They constantly ping, distract, and disrupt your team’s flow, so you spend your days switching between apps and tracking down feedback. It’s busywork, not the meaningful stuff. We want to change this. We believe there’s a more enlightened way to work. Dropbox helps people be organized, stay focused, and get in sync with their teams.

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.

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.

Crowdfunding has fueled an increase in innovative product companies turning to Chinese factories for production. Yet, Chinese factories seem undifferentiated because they all make the same, unverifiable claims of excellence. This results in competition centered on price. Factories are forced to under-bid contracts to win business, but often, they later surprise the customer with quality problems and delays. This process is broken. We install cameras and remote monitoring software on the assembly line, and this ensures compliance with test protocol, improves quality, reduces liability, and helps fight warranty fraud. We charge a nominal per-unit fee to the OEM and revenue share with the factory when they demonstrate compliance with quality standards (whether units pass or fail). It encourages better behavior from factories and rewards those who perform with an audit trail of good performance that helps them win new foreign business. On average, defect rate will fall 75% within 5 months of deploying Assembly at a factory.
