Make your business run smoothly again.
Your business runs on people, tools, and chaos. We fix the last part — with custom systems built around how your team actually works.
Growth exposed what used to work.
At some point, the way you run things stops keeping up with the business. What worked when you were 10 people starts breaking at 30 — clients slip through the cracks, updates live in ten different places, and your team spends more time chasing information than doing the actual work. You don’t need new software. You need the right structure behind the one you already have.
We help when…
- Your team runs on messages, memory, and luck.
- Everyone’s busy, but no one’s sure what’s actually moving forward.
- Reports take a day to build, and you still don’t fully trust the numbers.
- Clients keep asking for updates you thought they already had.
You’ve already built the business. We just help it run like it’s supposed to.
Trusted by
We build in code, not in theory.
Code-First Prototyping
We design directly in code, not Figma. Feedback comes from using it, not imagining it.
AI-Accelerated Development
AI handles the repetitive work so our engineers focus on flow and function.
Developer-Led Product Thinking
Small, autonomous teams who think like product owners, not order-takers.
The result: faster delivery, less back-and-forth, and tools your team actually uses.
From bottleneck to leverage: cutting delivery time by 95% and unlocking €900K in revenue.
When we first spoke with the founders, their team was hitting a wall. They had a solid business and a long list of clients waiting, but each new project was eating six months and a full engineering squad to deliver. What should’ve been growth had turned into gridlock: 30+ projects on hold, €900,000 in revenue frozen behind an impossible process.
We saw that the core issue was structure. Everything depended on people, not systems. So we helped them rebuild the process from the inside out. Together, we designed a custom internal platform that turned their manual workflow into a repeatable, modular system. Instead of coding every project from scratch, they could now configure, brand, and launch new ones in days.
By the end of month two, one non-technical team member was doing the work of 20 team members, and the company had cleared its backlog, released blocked revenue, and doubled its delivery capacity without hiring a single person. Everyone else could now focus on improving the product, rather than doing endless manual work.
Outcomes:
- 20+ team members → 1 operator
- 6 months → < 1 week per delivery
- €900K in previously blocked revenue released within two months
- Delivery throughput up 20×, with zero new hires
- Operational cost per project down 85%
What we built was leverage, not just software. They stopped scaling through headcount and started scaling through structure.
A lean, disciplined way to build internal tools.

"They understood our business in one call and built a tool that fixed a six-month headache."
— COO, Consulting Firm
"We’ve tried fancy dashboards before and none of them stuck. This one did. The team actually uses it every day."
— Founder, Creative Agency
From constant catch-up to full control: how we helped an agency regain clarity and 60% of its time.
When they reached out, they had great clients, steady growth, a talented 25+ person team. But behind the scenes, the founders were exhausted. Projects lived in five different tools. Updates got lost between Slack, Notion, and spreadsheets. They were leading by instinct instead of insight.
We started by mapping where time was really going, and we found that reporting, approvals, and chasing updates were consuming entire days. So we built a calm and connected tool that unified everything they already used.
One dashboard replaced the chaos: capacity, pricing, approvals, and live project status, were all visible, synced, and automatic.
Within a few weeks, their team had cut 60% of the time spent on admin, projects started shipping on schedule, and the founders finally had the headspace to think ahead instead of catching up.
Outcomes:
- 5 tools replaced with one connected system
- 60% less time spent on tracking and reporting
- Profitability per client visible in real time
- Faster approvals and smoother delivery
- Zero disruption to the team's workflow
The real win wasn't the dashboard, but the calm that came with it. Everyone knew what was happening, every day, without asking.
We're not an agency in the usual sense.
We build software differently — smaller teams, fewer layers, and faster feedback loops. The goal isn't to impress you with process; it's to help you get a system that actually works.
| Traditional Agency | 23harmony Studio | |
|---|---|---|
| Approach | Starts with workshops, mockups, and long planning cycles. | You get to test ideas early and see real progress fast. |
| Decision-making | Multiple layers of PMs, designers, and approvals. | One small, technical team that builds and iterates directly with you. |
| Speed | Fast at selling, slow at delivering. | We move quickly by focusing only on what actually moves the business forward. |
| Design | Heavy upfront design — then development. | Design happens inside the build. Form follows function. |
| Process | Deliverables over outcomes. | Real usage guides every next step. |
| Result | Polished presentation that takes months to implement. | A working system your team can actually use within weeks. |
We're not against traditional agencies — we just believe founders deserve a faster, calmer way to get useful software built.
