Twin Sun is a software development agency based in Nashville, TN. We build, rescue, and modernize software, specializing in custom web and mobile apps. Backed by 20 years in the industry, we've seen everything from BlackBerry to AI.
We move fast, with a 100% U.S.-only team, and our reputation is everything to us. We only take on projects we can deliver on and work we feel good about.
We don't just write code. We take time to understand your business, so the software we ship actually moves it forward- whether that's launching a new product, saving a project that's gone sideways, or dragging a legacy system into the modern era.
Why clients choose us:
A 100% U.S.-only team. No offshore handoffs, no timezone gaps
Fast delivery and transparent process
Fearless problem solving, especially on projects others couldn't finish
Dedicated developers who take ownership of your project
Direct access to the people doing the work, not a layer of account managers
What drives us:
Our team runs on four values, and you'll feel all four in how we work with you.
Ownership — When something lands on our plate, it's ours. The buck stops with us, even when the path isn't clear or the situation isn't fair. You'll always know where your project stands.
Do the right thing — We aim to be beyond reproach. We don't hide problems, and we don't optimize for ourselves at your expense. When there's tension between what's easy and what's right, we choose right.
Excellence — Our work makes people stop and pay attention. Excellence isn't perfectionism, it's judgment: we calibrate to what your project actually needs and always look for a better way.
Genuinely helpful — We don't pretend to have all the answers. When we don't know something, we say so, go figure it out, and come back with a solution. We tailor what we do to your actual goal, not just the task in front of us, and we're a genuinely good time to work with.

Online Review
Twin Sun reviews and overhauls a financial services company's legacy Ruby on Rails application to improve security, supportability, and performance. The project is still ongoing.
Twin Sun is still working on the project, but they've been meeting each milestone without negatively affecting the production or the users. They've released two major and several minor updates, improving the app's security and performance. Their team used Jira to ensure efficient project management.

BACKGROUND
Please describe your company and your position there.
I'm the CTO of a financial services company with offices across the United States
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Twin Sun, and what were your goals?
We need a massive overhaul of a legacy Rails application that needed to be brought into modern times.
SOLUTION
How did you select this vendor and what were the deciding factors?
I knew many of their people from previous endeavors so I didn't have to do much research.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
The project scope was an entire review of the product from the ground up to improve security, supportability, and performance. It's still ongoing with 2 major releases, countless smaller ones, and more yet to come. It's been a resounding success with little interruption to production users.
How many people from the vendor's team worked with you, and what were their positions?
We had 2 constantly assigned with several in advisory roles. The advisors came and went when their particular expertise was required.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
The effort has continued and will for some time, but each milestone has been met and has had no negative effects on production or our users. The benefits are more a secure and better performing product.
Describe their project management style, including communication tools and timeliness.
We used Jira for task management, but the day to day management is not something we needed to do. Our internal IT teams managed the rollout timing. We were pretty hands off on the day to day and just counted on the team to deliver on time, which they did.
What did you find most impressive or unique about this company?
I believe this team works best when you give them the goals, move out of the way, and let them get it done. When I outsource I don't want to spend a lot of time dealing with "issues" with the outsourced team. I didn't have any "issues" with this team, they just did the work and got it done.
Are there any areas for improvement or something they could have done differently?
I can't really imagine asking for anything more from them. They did exactly what they said they'd do and I believe we asked for a lot.

Our Story
We started Twin Sun because we were tired of watching software projects fail. The idea was simple: deliver every project we take on, do what we say, and do the right thing. Simple, not easy. But the hard part was never the technology. It was finding people who genuinely care and deliver.
Today we've built a U.S. only team that takes ownership, a process built for throughput and excellence, and a track record of projects and clients that we're proud of. Turns out the original idea was right.
Premier Verified means Clutch independently confirmed Twin Sun is a legally registered business, financially sound (Creditsafe: Low Risk), and backed by 20 verified client reviews averaging 5.0 stars.
