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

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.
