Mobile companion app
Alto (B2B Software for zoopla)
Through sale data analysis, I identified that a gap in mobile functionality was causing 45% of demo losses to competitors.

I designed and delivered a mobile companion solution that reduced demo losses by 91% and achieved 48% weekly retention.
My role
I owned the end-to-end project from the design side, working alongside a product manager, a team of engineers and a data analyst.

I conducted the discovery research, I facilitated a planning & delivery workshop and delivered pixel-perfect designs. I also set up launch messaging and user guidance.

Outcome
1. Context
Alto lacked a solution to allow agents while working away from their desk. This gap significant impacted our sales effort, with 45% of lost demos citing it as a reason for going with a competitor.

This was also hindering our user’s productivity, and forcing them to rely on  tedious workarounds to access data on their mobile devices.
2. Research
I conducted both quantitative and qualitative research to better understand the specific areas of the products our customers needed remotely.
🔎 User insights
I compiled the insights from 7 customer interviews and 1000+ survey answers to create an activity map (above). This highlighted specific product areas and features to focus on.
📊 Usage analysis
To further strengthen my findings, and measure our progress, I also looked at our mobile usage data, and workarounds prevalence.
💼 Business requirements
Stakeholders needed early indicators of competitive advantage and user adoption to validate the mobile-first strategy.
⚙️ Technical constraints
Modernisation to our legacy system required us to carefully scope our approach to deliver maximum impact within the agreed timeline.
3. Solution
I worked with the product manager and engineering leads to design a phased mobile experience that balanced user needs & constraints.

Designing the interface
My focus was on designing an interface to fit the user’s context: this companion is mainly used while out meeting clients, therefore users are often navigating it while multi-tasking. The key was keeping it easy and to the point.
Rollout & cohorts
I worked with the product manager to agree on a phased rollout with the goal of quickly iterating based on real feedback. After consulting with engineering leads, we agreed on 3 phases of delivery.
Customer education
Ahead of the first rollout, I worked with our content designer to craft some in-app messaging to help customer transition to this new experience.

This ensured a smooth transition cross-devices, while also allowing us to introduce early feedback loops to engage with customers.
4. Outcome
The reception of this new product matched our expectations: customers were excited for a step in the right direction, and really like this first iteration, but more functionalities were needed to meet their needs.
Customer sentiment
I collated over 300 user comments based on on-going feedback and a post-rollout survey. This showed 82% satisfaction, but within this 90% included requests for further features.
Retention and behavioural changes
These insights were further validated by usage data.

The mobile companion provided more information than the diary export, but not the printout. This aligned with the change in behaviour in one, but not in the other, and the request for further features.
5. What's next
As we had expected, customers were requesting further feature. I continued to work with the product manager to present our results and pitch for a second phase to the product leadership.

Thanks to all our feedback and data collection, we already had a detailed plan of what we believed should be our next focus.
Outcome of our second release:
- 62% in diary prints
compared to -14% after the first phase
86% weekly retention (after 90 days)
compared to 48% after the first phase
+5 points to NPS score
Based on heavy mobile users compared to whole user base
