About Rocket Harbor

Rocket Harbor is a software development company founded in 2016. We design, build, and maintain high-quality digital products for clients who value technical depth, honest estimates, and clear communication from kickoff to delivery.

Over the years we've delivered ERP systems, Transport Management and Applicant Tracking platforms, Learning Management and EdTech solutions, Marketplaces, SaaS products, and complex API integrations. We also help businesses modernize legacy systems without disrupting what already works.

Our team of 5–10 senior specialists covers the full delivery chain — back-end and front-end engineers, mobile developers for iOS and Android, UI/UX designers, QA engineers, and DevOps. Every project goes through a structured discovery phase where we define architecture, scope, and budget together before writing a single line of code.

We don't overcommit. We take on projects we can execute well, and we stay accountable to the plan we agreed on. If you need a reliable technical partner, we're ready to talk.

We brought Rocket Harbor on as our technology partner, and what followed has been nothing short of transformative. In the transportation industry, you need a team that actually understands the space — not just developers who build off tickets without context. Rocket Harbor is the rare exception. Together, we built a decentralized plug-and-play marketplace for the transportation industry on a .NET stack — think Expedia, but for freight and transport. With a team of seven full-time engineers plus additional support, they helped us get there faster and more cost-effectively than I thought possible. Over $500,000 invested, and we've reached a $30 million company valuation in two years. The speed-to-value ratio has been remarkable. What sets them apart is their honesty and domain depth. They don't just execute — they question edge cases, challenge assumptions, and proactively surface new technologies that keep our infrastructure lean and optimized. They never let us overspend on unused servers or software, and their invoices are always clean and accurate. That kind of integrity is rare and invaluable. At this point, they're not a vendor — they're family. Our fourteen people and their seven operate as one unified team. I can't find areas for improvement; if anything, I just wish I could hire more of them.

We brought Rocket Harbor on board in November 2018 to help us scale an in-house web application built by a single developer. What started as a fragile, monolithic structure is now a robust, microservices-based platform built on .NET Core and Azure — and we've been working together ever since. Over $300,000 invested, and the value has been clear from early on. One of the biggest wins was setting up Azure DevOps for continuous integration, which streamlined the way updates are published. We see meaningful improvements every week. The application now aggregates data from multiple APIs and presents it in a clean, decision-ready format for management. More recently, Rocket Harbor built a production-grade multi-agent AI support system integrated with Microsoft Teams and REST APIs. It covers AI-assisted workflows, intent classification, retrieval-augmented generation, knowledge retrieval, and agent-based automation — all with proper multi-agent orchestration and tenant context isolation. The system is fully multi-tenant and deeply integrated with Microsoft 365, which fits naturally into how our teams already work. The team is reliable, communicates quickly when obstacles arise, and consistently meets deadlines. What impresses me most is their adaptability — throughout the project, we've had several changes in direction, and they handled each one with minimal friction. They find solutions that actually save us money. No complaints, just results.

We partnered with Rocket Harbor in January 2022 to outsource our software development, and it's been one of the best decisions we've made. Their team handles everything — DevOps, UX/UI design, API, web, iOS, and Android development. We started with a small project; they delivered beyond our expectations, and we've been working together on a much larger engagement ever since. Over three years and close to $2,000,000 invested, Rocket Harbor has consistently delivered on time and within budget. Communication is seamless — weekly Teams calls, Jira for project management, and a dedicated point of contact (Serhii) who keeps everything running smoothly. Their work has given our customers a significantly better technology experience, dramatically increased our sales, and set us apart in our industry. The team's professionalism and the quality of their output are truly their biggest strengths. I have no areas of criticism — they've made us a better company, plain and simple.
