In the era of digital transformation, composability (or the use of modular components) has become a new frontier. Many companies are pursuing this architecture to develop complex systems connected to their technology stack. However, making these systems a reality can be challenging, especially due to data silos and distributed architectures. Recently, Fastn, a Texas-based startup founded by former Amazon engineering manager Khalid Muaydh, announced that it has raised $2.6 million in seed funding to address these issues and pave the way for building high-performance composable applications driven by AI. At its core, Fastn develops a no-code/low-code platform that leverages AI agents, automation, and drag-and-drop interfaces to simplify the creation, integration, and orchestration of modular components required in application development. This includes APIs that provide real-time access to business-critical data scattered across data silos. "Our unique approach focuses on composability, making it easy to integrate various systems and data sources. This not only accelerates the development process and reduces costs but also enhances the agility, reliability, and scalability of enterprise solutions," said Muaydh to VentureBeat. Building a Unified Enterprise API Muaydh founded Fastn in 2023 after encountering numerous bottlenecks while building complex systems for his former employer. The biggest problem, he said, was that traditional architectures required developers to manually manage multiple custom APIs and their integration in different data environments. This involved complex coding work that was slow and prone to errors. Fastn solves this problem by allowing users to build a unified enterprise API using natural language prompts. Essentially, users can describe the functionality of their application, and within seconds, they will receive the building blocks of that application - functional APIs - generated by AI agents on the platform. "With our API AI agent, users can describe the type of API they need - whether it's reading or writing information on any topic - and the system will generate a production-ready, enterprise-grade API. Users can choose to confirm the details of the API or further customize it through prompts. Similarly, our connector AI agent allows users to create integrations for systems or applications not pre-integrated with Fastn, enabling efficient custom connection building," explained Muaydh. Once the API is ready, users can connect it to data sources such as databases, spreadsheets, or other applications to extract information almost in real-time. Fastn claims to provide data in milliseconds, which is crucial for applications like e-commerce product pages. However, the work doesn't end there. After connecting the data, Fastn allows users to build the logic of their applications using pre-built or custom components to handle tasks such as data transformation, computation, or decision-making. Additionally, it provides the ability to monitor application performance in real-time, allowing users to gain insights into key metrics such as p50, p90, and p99 latency, as well as data flows across all connections. "If a part is not working as expected, you can quickly identify and resolve the issue. When you're ready to deploy, you can simply click a few times to deploy the application to different environments. To ensure reliability, users can test each generated API or connector to validate its compliance with our high standards for enterprise performance. If needed, users can further modify it without writing any code," added Muaydh. While Fastn is still in its early stages with only $2.6 million in funding, its approach to building composable applications has garnered attention. Since its launch on Product Hunt in July 2024, the company has attracted over 450 users to test the platform in their workplaces. Recently, it also signed HP as its first official enterprise customer. "HP seamlessly integrates its applications with customer environments using Fastn, adopting a composable architecture... For example, when HP signs and onboards customers with different support systems, Fastn's platform automatically maps and orchestrates data between HP systems and customer support systems, regardless of format or environment. This real-time connection breaks down data silos and eliminates the need for extensive custom development, allowing HP to deliver value to customers in minutes instead of months," explained Muaydh. He added that they are currently in talks with a dozen medium-sized enterprises and enterprise customers. However, as the integration and orchestration market grows, it will be interesting to see how Fastn differentiates itself from long-standing and well-funded competitors in the field, such as Mulesoft and Snaplogic. According to Mordor Intelligence, the system integration market is expected to grow from $485.41 billion in 2024 to $778.92 billion in 2029, with a growth rate of nearly 10%.
