Case study MOBILE APP

From idea to Sabancı-backed platform in under four months.

Kidu set out to be the safe ride service for children, born inside Sabancı's intrapreneurship program. A two-person founding team with no engineers needed a parent app, a driver app, and an admin platform, fast. ETREXIO built all three.

01 A corporate startup with a two-person team and a running clock

An Uber for children, with no one to build it

Kidu began inside Sabancı ARF, the conglomerate's intrapreneurship program. Sevim Örs, a Sabancı employee, was selected into the program with a sharp idea: safe, accountable transport for children, an Uber for kids aimed at busy white-collar parents who need their children moved safely while they work. The founding team was two people. Neither was an engineer, and the program's clock demanded a working product fast.

The project reached us through a chain of trust. A consultant advising companies on intrapreneurship, an old school friend of Kemal's, told them plainly that this was a job for Kemal and Furkan, and with the support and approval of the ARF program's leadership, we took on everything technical: parent app, driver app, and the web admin behind both.

02 Every feature answers one question: is my child safe right now

Trust, engineered

The flow starts with a parent posting a ride request. Vetted drivers bid, the parent accepts, and the trip begins with live route calculation and real-time location on the parent's screen.

The child's side of the app is its own design problem, solved with emoji and photo-based screens for kids who cannot yet read, kept fully separate from the parent's view. Every trip ends with a happiness score, so the quality of a ride is measured by the person the service actually exists for. The drivers were not strangers off the street: professionals who already did this work through tourism agencies and ride platforms, invited one by one and onboarded personally by the Kidu team. For them, Kidu meant a safer and better-paying line of work than the platforms they came from.

Underneath the two apps sat the web admin, where the Kidu team managed requests, drivers, and every live trip, because a two-person founding team needs the operations side handled as much as the customer side.

  • Parent app with ride requests, driver bids, and live tracking
  • Child screens built with emoji and photos for pre-readers
  • Happiness score closing every trip
  • Drivers invited and onboarded personally, one by one

03 Route deviation alerts, tested by real traffic

The times the alarm actually fired

The system's sharpest safety feature was the route deviation alert: if a vehicle strayed from its calculated route, the operations team was notified instantly and called the driver on the spot.

That alert fired several times in real life. Each time, the team was on the phone within moments, and each time the explanation was ordinary: an accident up ahead, heavy traffic, a detour any parent would have taken themselves. Not one case involved bad intent. That is exactly the point. Parents could relax not because nothing ever deviated, but because something was watching every ride, all the time, and reacting in minutes. Trust was not a promise on a landing page. It was a system behavior that had been observed working.

04 When Güler Sabancı hears your pitch, you listen back

Feedback from the very top

Because Kidu grew inside Sabancı's program, the product was pitched to an unusual audience: senior general managers across the group, and Güler Sabancı herself, listened and gave feedback.

One piece of that feedback became a feature. A deputy general manager suggested shared rides, and we built it: multiple families sharing a single minibus on a common route, cutting the price per family while keeping every safety mechanism intact. Cheaper and safe is a rare combination in child transport, and it came from treating a boardroom pitch session as user research. The pilot audience responded in kind, with the strongest traction landing precisely in the busy white-collar parent segment Kidu was designed for.

05 An investable platform in one season

The outcome

In three to four months, a two-person team with no engineers had a full platform running pilots in Istanbul, Ankara, and Izmir, with hundreds of rides completed in Istanbul alone. Sabancı invested $150k on the strength of it, with the company's most senior leadership having heard the pitch and shaped the product along the way.

Kidu's ending is honest startup history: after a strong run, the venture could not outlast the pandemic and the funding contraction that followed, and wound down operations for financial reasons a few years ago. What the project proved still stands. When the product side is fully handled, two founders and a single season are enough to take an idea from a program pitch to an investment committee's yes. Three applications, zero engineers on the client side, one season on the clock: that ratio is the case study.

Questions

About this project

Our corporate venture has no engineers. Can you be the entire product team?

That was Kidu: a two-person founding team inside Sabancı's intrapreneurship program with no engineers anywhere. ETREXIO designed and built the parent app, the driver app and the web admin, everything technical, in three to four months. You bring the venture and the decisions; we bring the whole build organization.

How fast can an intrapreneurship project show a real product?

About one season. Kidu went from idea to a working platform piloting in Istanbul, Ankara and Izmir in three to four months, and Sabancı invested $150k on the strength of it. Corporate innovation programs run on demo days and committee calendars, so speed to a real product is the whole game.

Can you build for safety-critical requirements?

Yes, as design inputs rather than afterthoughts. Kidu's rides ran with live route calculation and instant alerts on any route deviation so the operations team could call the driver on the spot, drivers were vetted professionals invited and onboarded personally, and children got emoji and photo-based screens made for kids who cannot read yet.

Corporate stakeholders will pile on feedback. How do you handle that?

We treat good feedback as free product work. At Sabancı, senior executives reviewed Kidu directly, and one general manager's suggestion became the shared rides feature, which let several families split one vehicle and lowered the price of a safe trip. The build absorbed executive input without the timeline slipping.

What happens if the venture ultimately fails?

Kidu eventually wound down for financial reasons after the pandemic and the funding contraction, and we say so openly. What the build proved still stands: with the product side fully handled, two founders reached pilots in three cities and an investment committee's yes in a single season. Ventures carry market risk; execution risk is the part you can remove, and a Clarity Call is where we remove it.
