  • 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.

  • Retell AI
    Retell AI (w2024)Active • 5 employees • San Francisco, CA, USA
    We help developers implement human-like voice agents in a day instead of months. Plug in your LLM, a voice agent is born! From AI-powered call agents to voice-enabled coaching apps and lifelike companions, we are your trusted ally in turning these visions into reality. Although Voice AI has been around for some time, it hasn't yet become effective enough for mainstream use, primarily because of poor user experience. Conversational flows often feel awkward with unnatural pauses and interruptions, requests are frequently misunderstood, and voices sound robotic or overly dramatic. On top of that, setting up such a Voice AI system can require upwards of 100 hours of frustrating development. By offering a truly conversational, fast, and empathetic Voice AI that can be easily configured for any industry and integrated into any product, we aim to push the boundary of user-friendliness to a new level, reaching the threshold for mainstream adoption of Voice AI. We are at a pivotal moment in history where Voice AI will become the primary interface for accessing products and services, revolutionizing our interactions with machines for the better. Retell AI is at the forefront of creating this new reality.

  • Vue Storefront
    Vue Storefront (w2021)Active • 100 employees • Warsaw, Poland
    Vue Storefront is a Frontend Platform (Head) for Headless commerce. Available as Open Source & Enterprise. By implementing Vue Storefront, you will improve your overall User Experience and lift up your revenues by at least 20%. 1. Lightning Fast We are on a mission to improve loading times for eCommerce users, especially on mobile devices. We want to make sure, that every site using Vue Storefront will load in under 2 seconds for all users across the globe. Currently, it is their weak spot: a) It takes, on average, 15.3 seconds to fully load a mobile page. b) 75% of mobile sites take longer than 10 seconds to load. c) 53% of mobile site visits are abandoned if it takes longer than 3 seconds to load. Loading times mean better User Experience and this leads to eCommerce users buying more, giving better conversion rates: a) Walmart found that for every 1-second improvement in page load time, conversions increased by 2% b) Increase of conversion % at each stage of the Customer Buying Journey at eCommerce based on 0.1s improvement based on Google Research (https://www.thinkwithgoogle.com/future-of marketing/creativity/mobile-page-speed-data/) 2. Fast Time To Value Vue Storefront is the glue for headless commerce, giving merchants the ability to connect with any eCommerce backend, any CMS, or any other 3rd party service, as we provide those APIs by default in our cloud platform. This is saving our clients thousands of development hours. Also, because of the Progressive Web App features that we provide, there is no need to build native iOS or Android apps - everything is available through the web. In combination with frontend components provided out of the box, it is possible to build a new eCommerce frontend within weeks, not months. 3. Fast content adjustments with any Headless CMS Headless CMS is the only way to embrace omnichannel sales, and we know it. That is why the Enterprise version of Vue Storefront delivers the API-first setup of integrations with the best Headless CMSes out-of-the-box. It allows business users to edit the content & publish with a no-code approach 4. Fast learning curve for developers We use the modern tech stack that is easily adaptable by the developer community, and what is better market proof than the popularity of our Open Source Project? We are currently the 5th most popular eCommerce framework globally and the 1st Frontend eCommerce Framework globally! https://docs.vuestorefront.io/v2/ https://www.vuestorefront.io/

    Tailor (s2022)Active • 16 employees • Tokyo, Japan
    Tailor is a backend platform that helps enterprises build their custom, enterprise grade ERP applications with less code. **Team** Yo and Misato have previously built a retail-tech company together and sold it for $20M to Rakuten. Yo is a three-time-acquired serial entrepreneur with a McKinsey background. Misato is a previous head of R&D at Mercari. Tailor is the first YC company fully based in Japan. **The Problem** In today's business world, old ERP systems just don't keep up. Their monolithic architecture makes it difficult for developers to tailor to the specific needs, even though that's what the enterprises want for ERP. At the same time, legacy ERPs struggle to work well with the variety of cloud-based tools that modern businesses rely on. Legacy, monolithic systems make it very difficult to customize and hard to integrate. Every time the company wants to change something, it becomes a huge project. Building on these challenges, users of old ERP systems often face: * Hard-to-Use Interfaces: The screens and menus are old school... confusing, slowing down your work. * Wrong Set of Features: Too many unnecessary options for you and not enough of what you actually need. * Lack of Transparency: It's tough to understand what's happening behind the scenes. * High Cost: The expense of maintaining these systems eats into your budget. **The Solution** Why Headless? - With our headless product, the frontend is easy to customize for clients - API-first approach makes it easy to connect with other existing systems or 3rd party services What does it mean to our clients? - Faster development - Reduced maintenance cost - Well-documented backend APIs Tailor’s key capabilities: - GraphQL endpoint for flexible frontend development - Customizable data model templates to describe complex business logic of large enterprises - Customizable workflows depending on the client's specific business process - Directory service that can reflect complex organizational structure (e.g. matrix organization) to the workflow

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.

    sizeless (s2023)Active • 2 employees • San Francisco, CA, USA
    Sizeless is a platform to help ML teams automatically run, test and improve their models to make ML reproducible and safe. Currently, ML engineers do this manually which takes weeks - we automate this down to a few clicks. ML engineers at Google shopping and computer vision startups are using our platform to shorten their ML development cycle and continuously monitor and fine tune their models. We provide ML engineers with a productivity tool set, so that they can focus on building great ML models. We developed this tool during our PhDs (Cornelius in ML at ETH Zurich and Roger in astrophysics at Cambridge), saving us and our PhD colleagues around 2 weeks per model while generating actionable insights. We launched 10 days ago, have 5 daily active users like ML engineering teams at Google Shopping and in computer vision startups and more than 50 sign ups on our waitlist. We provide ML engineers with a productivity tool set, so that they can focus on building great ML models.
