TL;DR: When Kılıç Arslan Doğan and his team at MatlubApps built Fixy AI, they created an AI grammar utility loved by students, language learners, and authors worldwide. But as the app matured, they faced the classic studio decision: keep juggling ongoing marketing maintenance on a single product, or unlock its equity to scale their broader portfolio.
By executing a direct, zero-commission exit to Rounds, MatlubApps eliminated cross-border wire anxieties, secured immediate liquid capital, and reinvested 100% of the proceeds into new marketing channels, specialized consultants, and next-generation app builds.
In short: Kılıç Arslan Doğan, co-founder of MatlubApps in Ankara, Turkey, built the AI grammar correction app Fixy AI and sold it to Rounds.com, the AI-powered mobile asset platform. The studio put the proceeds into new marketing channels, specialized growth consultants and its next apps. His lesson: selling an app you love isn't the end of its story, it can be the beginning of your next one.
Hey readers,
Welcome back to Rounds Insights. Every week, we break down real-world growth mechanics, software asset trends, and exit playbooks directly from active developers.
Today, we’re taking a look inside MatlubApps, an agile software studio based in Ankara, Turkey, and how their co-founder, Kılıç Arslan Doğan, turned their flagship utility into liquid growth capital to scale an entire ecosystem of products.
Let’s dive in. 🚀
1. Building Fixy AI: From Studio Vision to Global Traction
When Kılıç and his co-founders launched MatlubApps, Fixy AI was the core thesis. Designed as an intuitive AI grammar correction tool, the app quickly gained traction among international students, authors, and professionals who needed fast, reliable writing assistance.
Combining sharp product development with focused organic marketing, the team hit rapid growth milestones. Fixy AI wasn't just generating revenue—it was building an active, global community.

"After a while, we realized that Fixy AI was no longer just a product to us," Kılıç reflects. "It had become an invisible bond connecting us with users around the world. We took all the know-how and marketing experience we gained from Fixy AI and used it as the blueprint for our company's future builds."
2. The Decision: Software as Liquid Capital vs. Operational Drag
As Fixy AI reached a stable, monetized baseline, the team at MatlubApps arrived at a pivotal strategic junction.
They could continue allocating engineering hours and marketing focus toward maintaining a single mature utility, or they could transition the asset to Rounds.com, the AI-powered mobile asset platform, equipped to scale it long-term, unlocking immediate liquid capital to fund their expanding studio roadmap.

When the team at Rounds reached out with an initial evaluation proposal, Kılıç recognized the leverage:
"We saw it as an opportunity to use the proceeds from the deal to explore aggressive new marketing channels, bring in top growth consultants, and develop our next pipeline of apps."
3. Overcoming Cross-Border Payment Anxieties
For international developers outside major Western financial hubs, selling a digital asset can feel intimidating. Questions around cross-border bank wires, contract modifications, and post-sale server migrations often create hesitation.
Kılıç admits he had those questions at first, until peer-to-peer trust cleared the path.
"To be honest, I was a little concerned about the international bank transfer at first. However, once we spoke with Turkish developer colleagues who had previously completed direct transactions with Rounds, those concerns quickly faded. Everything went smoothly."
The Operational Hand-Off & Post-Sale Integrity
When technical edge cases arose during code migration, the human element made the difference. When Kılıç’s team requested specific contract adjustments, they were handled directly and transparently.
Even more impressive was what happened six months after the deal closed.
When the MatlubApps team discovered that legacy API costs for Fixy AI were still accidentally running on their local servers, they brought it to Rounds' attention. The Rounds team covered the entire retroactive expense immediately and without hesitation.
"They were always very understanding and responsive," says Kılıç. "I really appreciate Alva, Ivana, Nir, and the entire team for being so patient and explaining every step clearly."
4. The Result: Funding the Next Generation of Apps
Executing a direct exit didn't mark the end of MatlubApps' momentum, it accelerated it.
By transitioning Fixy AI at the right moment, the studio secured the capital required to hire specialized growth consultants, experiment with new acquisition channels, and fund the development of their next suite of mobile applications.
[Mature Software Asset] ➔ [Direct Capital Liquidation] ➔ [Multi-App Studio Scale]💡 Kılıç’s Advice for Software Builders:
Don’t be afraid to sell something you’ve built, even if you have a strong emotional connection to it. As developers, we spend so much time building and improving our products that they start to feel like a part of us.
But selling an app can open the door to new ideas, bigger projects, and major capital opportunities. If the right opportunity comes along, selling your app isn’t the end of its story, it can be the beginning of your next one.
💡 Key Takeaways for App Founders
Treat Software as Liquid Assets: Mature utilities shouldn't sit on your console collecting maintenance debt out of habit. Liquidating stable assets unlocks the capital needed to scale new ventures.
Verify Through Peer Trust: When evaluating acquirers, look for platforms like Rounds.com, the AI-powered mobile asset platform, with transparent cross-border payment rails and verified developer track records.
Focus on Portfolio Velocity: Reinvesting exit proceeds into specialized consultants and new product development is the fastest way to evolve from a single-app developer into a multi-asset studio.
