SERVICES

So what exactly does Eegilsoft do?

If all you have is an idea

It’s fine if you don’t know how to build it. We turn your idea into concrete requirements through an expert’s eyes, and design an architecture that implements them accurately and efficiently. We deliver software of the quality you expect on the date we promised, and we stay responsible for maintenance after launch.

If you want to test the market first

We build an MVP (Minimum Viable Product) — a first version with only the essential features — very quickly. It is designed from day one so that, once the market responds, you can add more features with minimal changes instead of rebuilding. Fast never means compromising on quality.

If you want less repetitive work

We look at your repetitive tasks together and propose the best way to solve them efficiently with technology. Instead of bending your work to fit an off-the-shelf product, we build tools that fit your work.

If your current system has problems

We start by finding the root cause. Then we prescribe a lasting fix — what to change and how in the long run — so similar problems don’t come back.

If your project has stalled

A stalled project is not a lost cause. We quickly get up to speed on what has been done, reuse as much of the existing work as possible, and get you back to the goal you started with.

If you want a privacy and security check

We review whether your system properly protects personal data, and find and fix security risks before they become problems.

If you want to be more productive with AI

We study how your company works, find where AI will make the biggest difference, and recommend how to adopt it. If needed, we build it for you, too.

If you want to discover the value in your data

We work through it with you — from what data to collect, to how to analyze it and what you can build with it. We then propose a range of possibilities so the data you have gathered can help you solve harder problems.

Whatever problem you want to solve with IT, big or small, Eegilsoft finds you the best way to solve it.

WHAT’S BEST FOR YOU

Is Eegilsoft always the best choice?

The ideal is to have your own in-house development team, focused solely on your company’s problems.

But if you’ve found this page, it’s probably because you don’t have a development team you can rely on right now.

That said, if you’re simply looking for the cheapest team, Eegilsoft may not be the right fit. We are a team that delivers high-quality IT solutions at a fair price.

While we work together, we want you to feel as if you had your own in-house team that treats your work as its own. We take pride in our quality — please judge us by our value, not just our price.

03With a deep understanding of AI agents, we build software faster without compromising quality.
  • We have used AI agents — the latest way of building software — in many ways in real development.
  • We have experimented with and refined AI-agent-driven development ourselves, creating a way of working that solves client problems as quickly and accurately as possible.
  • Experienced experts check, from start to finish, that the AI is heading in the intended direction.
  • As an AI-native company, we maximize AI across all our systems to deliver high productivity and quality with a small team.
04A new AI era calls for a new development process.
  • We make the important decisions up front. Building software takes countless decisions. Drawing on our experience and design skills, we move the decisions that are hard and costly to change later to the very beginning.
  • People and AI each do what they do best. Instead of traditional role divisions, we redesigned roles to get the most out of both people and AI. Because every one of us is always looking for the most productive way to work alongside AI, we work far more efficiently than the traditional way.
  • It’s not just about churning out code with AI. We build software in the way best suited to the AI era. We take the many features that services commonly share, verify each one carefully, and keep them ready as building blocks. Then we assemble those blocks quickly to fit your requirements. That is how we can promise high quality while moving fast.
05We are exceptionally good at understanding complex requirements and turning them into clear technical language.
  • Across many industries, we have defined requirements directly with business stakeholders and turned them into designs.
  • We understand the business before the technology. Before asking what to build, we ask why it’s needed.
  • We communicate in language our clients understand.
06We have spent years delivering projects proven in the real market.
  • We have been through every stage, from defining requirements to launch and maintenance, so we are strong in practice.
  • We have resolved many sudden outages and tough problems to the end, so we stay steady in a crisis.
07However many users you have, we design an architecture that fits your scale.

We have designed everything from a startup’s first system to global services used by tens of millions. We don’t overbuild from day one; instead, we design so that your service can scale as it grows, without being rebuilt.

08We know the hidden costs of software development.

The cost most often overlooked in development is maintenance. Poorly built initial development leads to much higher maintenance costs later. Eegilsoft stops costs that are invisible at development time from piling up later — right from the start.

  • We design structures that are easy to fix and extend, cutting the time and cost of changing features after launch.
  • We identify and address risks that come back as large costs later — security, privacy and user growth — during development.
  • We leave design and technical documentation behind, so a change of hands never means paying to figure everything out again from scratch.

TEAM

What kind of team is Eegilsoft?

  • Our leader, a Seoul National University graduate with 20+ years in software development, talks with clients directly and builds their products hands-on.
  • Every core member comes from Korean big tech, with 10+ years of software development experience.
  • We bring together seasoned experts from many fields, so chances are we have already faced — and solved — the problem you are facing.
  • We believe technology is only a means; what matters is solving the client’s problem in the most sensible way.

FAQ

Frequently asked questions

Roughly how much does it cost?

Software development costs can be estimated in many ways, so there’s no one-line answer. Many factors have to be considered together: the complexity of the system, how hard the requirements are to implement, the seniority of the people involved and the development time needed.

What we can promise is this: using the latest development methods, Eegilsoft does its best to offer the most reasonable price for delivering a high-quality product on the date we promised.

Is there a fee for a consultation or quote?

No, consultations and quotes are free. Consultations mostly take place by email, and depending on the size of the project, we may need to meet in person. No costs of any kind arise until a contract is signed.

Do you take on small projects?

Our most important value at Eegilsoft is helping anyone build good software, easily. So the size of the project doesn’t matter. Even if it’s a small job, please don’t hesitate to reach out. We’ll do our best to find a way to solve it together.

Can I hire you even if I know nothing about software development?

Of course. There’s nothing to worry about. We won’t confuse you with technical jargon — we always explain things in words you can understand.

What happens if requirements change mid-project?

Even finished software has to keep changing as its environment changes. That’s why Eegilsoft treats embracing change as a basic principle of development, and expects and prepares for requirements to change mid-project from the very start.

That said, depending on the scope of a change, contract terms such as cost or timeline may need to be adjusted. In that case, we first explain how the change will affect the project, and proceed only after we have discussed it thoroughly with you.

Is software built with AI secure?

Security is one of the most basic features any software must have. But AI won’t take care of security on its own. That’s why Eegilsoft identifies security risks from the design stage onward, and designs and builds to the highest level of security.

What if the result doesn’t meet my expectations?

We know that results falling short of expectations is where the biggest conflicts between clients and outsourced developers arise. And it isn’t only about quality — delays can be just as frustrating.

That’s why Eegilsoft shows you progress and interim results regularly throughout development, so we can catch anything that drifts from your expectations early. If the result still falls short, we look into the cause together with you and do our best to resolve it in a reasonable way.

Who owns the deliverables (source code, documents)?

The deliverables we hand over to you (source code, documents) are yours. Once you have verified them through final acceptance testing and all the conditions set out in the contract have been fulfilled, we hand over the deliverables in full right away.

Can another vendor or our own team take over later?

Absolutely. At Eegilsoft, we take pride in building software that anyone can easily understand and maintain. Beyond working software, we also provide design documents and detailed technical documentation — so whoever takes over, whether another vendor, your own team or even an AI coding agent, can pick up development right away.

Do you also handle maintenance after development?

Yes, we do. For a set period after delivery, we fix defects that arose during development free of charge. After that, operations and feature improvements are handled under a separate maintenance and operations contract, apart from the development contract.

Because we know the systems we built better than anyone, we can start maintaining them right away without a separate system analysis — and we offer maintenance on more favorable terms as a result.

Will our ideas and information be kept safe?

All information we receive from you is managed at the highest security level, and every team member is trained to handle client information safely. If you wish, we sign a non-disclosure agreement (NDA) from the consultation stage.

We know better than anyone that if we can’t protect our clients’ ideas, data and assets, we can’t earn their trust — and without trust, we can’t survive in this market. That’s why Eegilsoft puts the security of client information above all else.

Can we meet in person for a consultation?

Yes, that’s possible. That said, Eegilsoft values efficient communication that respects everyone’s time. So the first consultation starts by email, and most conversations can be had just as well over email and video calls.

If, as we talk, it becomes clear that meeting in person would better serve the project, we’ll arrange a meeting then.

Do you work with companies outside Korea?

Of course — we always welcome projects from companies outside Korea. Our team has launched services for users around the world many times, and we believe good software knows no borders.

Wherever we can work together, we’ll gladly welcome companies from any country and software in any language. Meeting new clients in new markets is always exciting for us, too.

What does “EEGIL” mean?

In Korean, “Eegil (이길)” carries two meanings: “this way” (이 길) and “winning” (이기는). We want to be a partner that shows you the right way for your software, and helps you win in your market.
