How instacar Used Microsoft Clarity to Streamline Digital Leasing and Increase Conversions
When instacar set out to modernize vehicle leasing in Greece, they needed visibility into every step of the customer journey. By using Microsoft Clarity to understand real user behavior, the team uncovered hidden friction, improved usability, and boosted conversions across web and mobile.
About instacar
Launched in 2019 by Antonis Samothrakis and Antonis Zois, instacar is redefining how people and businesses in Greece access vehicles. What started as a vision to modernize the rigid leasing industry has evolved into a fully digital mobility platform — one that combines flexibility, transparency, and customer-first design.
Today, instacar offers a seamless digital leasing experience for both individuals and small-to-medium businesses. Through its website, mobile app, and internal fleet management system, customers can lease, buy, or manage vehicles end-to-end — from selecting a car to signing, uploading financial documents, and scheduling delivery.
As the platform expanded, so did its need to ensure every digital interaction — from quote requests to document uploads — was intuitive, fast, and reliable.
To solve this problem, Dimosthenis Avgeris, Head of Product at instacar, decided to dig deeper than surface-level metrics and understand each of these user interactions.
The Challenge
instacar’s booking process is the heartbeat of its business. The journey involves multiple critical steps, including requesting a leasing quote, uploading financial documents, completing payments, and finally confirming delivery.
But while high-level analytics tools showed drop-offs within the flow, the why behind them remained unclear.
“Users often dropped off or made errors, but it wasn’t clear at which step or why,” said Avgeris. “Since most of our traffic is mobile, we needed to be sure the flow was robust on all device types and screen sizes—something that wasn’t visible with numbers alone.”
The team faced several challenges:
- Unclear drop-off points in the quote and document upload flow.
- Mobile usability issues, with CSS or UI inconsistencies affecting experience on certain devices.
- Friction in exploration, as users navigated car listings, filters, and pricing tools.
- Limited visibility into how users understood the platform’s unique selling points or handled complex interactions like financial form uploads.
Traditional tools like Google Analytics provided aggregate data but lacked the session-level insight needed to identify and fix specific moments of confusion or frustration.
That’s where Clarity came in.
The Solution
To bridge that gap, instacar implemented Microsoft Clarity across both its website and mobile app.
With Clarity’s session recordings, heatmaps, and smart events, the team gained the visibility they needed to:
- Watch real user sessions end-to-end.
- Detect rage clicks, slow load times, and usability issues.
- Track engagement with key elements like filters, forms, and galleries.
“Monitoring the full funnel with Clarity meant we could quickly detect where users experienced delays, confusion, or technical difficulties, and make targeted improvements,” Avgeris explained.
By combining Clarity’s qualitative insights with quantitative metrics, instacar’s product, engineering, and marketing teams could prioritize high-value fixes and move quickly from insight to action.
What They Changed
Using insights from Microsoft Clarity, instacar launched a series of data-driven UX and performance improvements across its booking flow and website:
1. Smart Filters for Car Discovery
- Redesigned the car listing filters to be more intuitive and mobile-friendly.
- Made the entire filter row clickable instead of just the checkbox, reducing frustration and improving the speed of product exploration.

2. Pagination Implementation

Added pagination to long lists of cars, improving page performance, and making it easier for users to navigate listings without feeling overwhelmed.
3. Car Gallery Redesign
- Revamped the car image viewing experience with an enhanced gallery and mobile navigation.
- Added zoomable images and easier swipe functionality to make browsing vehicle details smoother and more engaging.

4. Streamlined Financial Form & Document Uploads
- Redesigned the multi-step quote and financial data collection process.
- Simplified document upload screens with clear CTAs, error handling, and guidance to reduce user confusion.
- Ensured the flow worked seamlessly across devices and screen sizes.

5. Fully Digital “Add Driver” Feature

- Transformed a previously manual, pre-delivery process into a self-service flow accessible in both app and web experiences.
- Enabled subscription owners to invite additional drivers by email, with invitees completing the process digitally.
- Incorporated clear CTAs, required uploads, and in-flow error messaging for better guidance.
6. Marketing Campaign Visibility
- Redesigned promotional elements on the car page and car list experiences to reduce cognitive load and highlight active campaigns more effectively.
- Reorganized sections like “Similar Cars” to improve product discovery and encourage exploration.
7. Overall Usability & Friction Reduction
- Addressed UI inconsistencies and device-specific issues identified in Clarity session recordings.
- Optimized interactive elements to reduce frustration, such as rage clicks on filters or gallery navigation.
- Implemented small but meaningful UX tweaks across the booking flow, vehicle listings, and post-quote actions.

Conclusion

“Clarity helped us see exactly how users interact with our website, app & internal fleet management tool, highlighting frustrations and showing us where to focus our efforts,” said Avgeris. “Clarity is now part of how we make ongoing improvements, with decisions grounded in what users actually do, not just what we assume.”
By keeping the customer’s real journey at the center, and using Clarity to illuminate it, instacar continues to deliver on its mission: making modern mobility simple, flexible, and digital for everyone in Greece.
