    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.

  • Tailor
    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

  • Decentro
    Decentro (s2020)Active • 60 employees • Bengaluru, Karnataka, India
    Almost every company that has to integrate with the legacy financial institutions, faces several challenges when it comes to the product cycle. Not only are the APIs and documentations less available, but they are also old school and ridden with errors and loopholes. On top of that, the lack of a single point of contact from the underlying institutions, makes the already long integration cycle of 5 months feel like a temple run between different departments. And since those services break and update over time, you can imagine the nightmare in terms of coordination between the tech teams. We are a full-stack platform where you can come, select your desired modules, play in the sandbox, and launch your product with the APIs and SDKs within a couple of weeks! Not only that, but we also take care of all upcoming fixes, iterations, and updates without breaking any flow. It's that easy, as it should be. Welcome to the future.

    Our mission is to make the web more collaborative. We're not just making collaboration faster—we're crafting it to be the best. Today we’re all using online platforms more than ever before - building, researching, learning, connecting etc. And we're not doing it alone. We're doing it together with other people and machines, turning the internet into the world's biggest team. Yet, the web was built for solo voyages. We saw a shift when platforms like Figma and Google Docs brought a multiplayer approach, breaking down walls and inspiring seamless teamwork. At Velt, we're taking it further. We're on a mission to infuse the magic of collaboration into the fabric of the web—one app at a time. We aim to erase the lines between online and offline co-working, crafting an environment where distance is irrelevant, and 'flow' is the norm. Right now, more than half of work hours are spent on coordination and communication—less on creating. With Velt, we're setting out to reverse these figures, reducing time spent on logistical issues by over 90%. Imagine what we can create when we spend less time talking about work and more time doing it! We're building a better web—a web for us, for our team, for everyone. Join us, and let's accelerate the future of web together 🚀 Our Products: - Velt SDK (https://velt.dev/): JS SDK to add powerful collaboration experiences to your own product for your end-users. This helps you ship such experiences ridiculously fast, increase user growth and engagement. - Superflow (https://usesuperflow.com/): JS plugin to enable product, marketing and design teams to comment and collaborate directly on their websites. This helps them iterate and ship their products 10x faster. We’re a team of ex-Googlers. We've launched products like Augmented Reality in Google Search & Maps. Come build a better web with us 🚀

With AI-generated content on the rise, many contexts require differentiating it from human-authored materials to ensure authenticity and trust in the digital world. Making this distinction is especially crucial when there are possible implications for misinformation, spam, abuse, or cybercrime. Existing technologies are ill-equipped to do so, costing an annual $78 billion spent on handling deepfakes. Our API allows integrators to use AI to get ahead of AI easily, without having to spin up their own infrastructure. We train custom models in a zero PII environment, removing the risk of compromising user privacy. Ayman and Dylan met as undergraduate engineering students at the University of Waterloo. Each cofounder has over a decade of engineering and research experience. Ayman most recently spent 7 years at GitHub, contributing to several areas of the product, including building and scaling abuse mitigation infrastructure for over 100 million users. While at GitHub, she saw first-hand how AI-driven threats were evolving, including witnessing established methods fail to detect user profiles that were generated by ChatGPT. Ayman’s experience at GitHub and her dissertation research in machine learning-based cloud platform security at the University of Oxford drove her to found Nuanced. Dylan has over a decade of machine learning experience spanning industry and academia, culminating in a notable 6-year tenure as an Applied AI Scientist at Amazon. They both quickly agreed that online content creation and consumption were rapidly changing and wanted to build something to help online platforms address evolving authenticity concerns. This is why Nuanced provides a user-friendly API that helps restore the authenticity and trust of services.
