Ballast Lane Applications LLC

Ballast Lane Applications builds web, mobile and backend software for product companies. Its teams sit across the United States and Latin America, so clients get engineers in similar time zones to their own.

The firm uses AI inside its delivery process through what it calls a software factory, with senior engineers and product owners reviewing each decision. It also builds AI for clients. Work includes multi-agent systems using LangChain and LangGraph, machine learning model design and fine-tuning, data pipelines, API integrations and retrieval-augmented generation. Standard services cover discovery, design, engineering, DevOps and quality assurance.

Clients can add engineers to an existing team or hand over a full project. Published case studies include Tripleseat, where the team added an AI menu importer and modernised event workflows on a hospitality platform, and Zeitview, where it works across front end, back end and infrastructure on a platform overhaul. The firm is based in Marblehead, Massachusetts, with engineering in Medellin, Colombia.
