AR integration that increased session length by 35 percent within the first month

Feb 13, 2026

Project summary: Our engineering capacity was committed to maintaining existing systems and could not absorb a net-new build of this complexity. An external partner with the right skills was the only viable option.

I came into this engagement as a sceptic. We had been through a failed implementation with a previous vendor and I had high standards for what evidence of competence looked like before I would trust a partner with our core systems. This team earned that trust progressively — through the quality of the discovery documentation, the rigour of the technical proposals, the consistency of the sprint deliveries, and ultimately the stability of the production system. I no longer lead with scepticism when recommending them.

PROS

Clear and consistent communication adapted appropriately for both technical and non-technical stakeholders, shared tooling that gave our team real-time visibility, reliable sprint delivery throughout

CONS

We underestimated the input required from our subject matter experts during the requirements phase. The team flagged this early but our resource planning did not fully reflect it — our responsibility, not theirs

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Hargrove Retail PLC operates in the Events & Event Management sector with headquarters in Manchester, UK. In my role as Director of eCommerce I am accountable for the full technology agenda — infrastructure, product, and vendor relationships. We are a commercially driven organisation and every technology decision is evaluated against a clear business case before it is approved.
What specific problem or business challenge led you to hire this company?
A competitive threat had accelerated our roadmap. We had planned a significant AR/VR Development investment for the following year. External pressure moved that timeline forward by six months and required us to find an external partner rather than attempting to build internally in the time available.
What services did the company provide for your project?
Primarily AR/VR Development, with adjacent work in solution architecture and quality assurance. They were responsible for the full build from requirements through to go-live, including integration with four existing systems in our technology landscape. The breadth they covered without requiring additional vendors was commercially and logistically valuable.
Why did you choose this company over other providers you considered?
We had a failed engagement behind us and were more rigorous in our selection process as a result. We asked detailed questions about how they managed scope change, how they handled estimation, and how they communicated problems. The answers were specific, evidenced, and consistent across the team members we spoke to. That gave us confidence that the process was real rather than rehearsed.
How clearly did the company understand your requirements and business goals?
Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.
How was your overall experience with their communication and project management?
The project management framework was the most structured I have experienced with an external vendor. Sprint planning was tight, acceptance criteria were specific, retrospectives were honest and acted on. The project manager treated the shared backlog as a live document and the risk register as an operational tool rather than a compliance artefact. I never had to ask for a status update.
Did the company deliver the project on time and within your expected budget?
Yes to both. There was a single sprint where a dependency on a third-party API introduced a one-week delay. The team identified it three weeks in advance, presented two mitigation options, and we agreed on an approach that recovered the schedule within the same sprint cycle. That level of foresight is what separates good project management from reactive problem management.
What tangible results or business impact have you seen since the project was completed?
We went live four months ago. User adoption exceeded the target we had set by 23 percent in the first month. Support ticket volume has dropped measurably. The features we had deferred because the previous architecture made them prohibitively expensive to build are now in development. The platform they built has opened our roadmap.
What did you like most about working with this company?
The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.
Would you recommend this company to others, and would you work with them again?
Absolutely. With a specific note that the value starts in the discovery phase — clients who approach that process with seriousness will get the most from the engagement. We invested appropriately at the front end and the returns are evident in what was delivered.

App store launch with a four-point-eight average rating in the first month

Sabrina Vollmer / Chief Innovation Officer - Rheintal Digital AG

Feb 05, 2026

Project summary: Our client portal had been built in 2017 and had not received meaningful investment since. Clients were contrasting it unfavourably with the portals of our competitors in pitches.

Our stakeholder group included board members, clinical leads, compliance officers, and end users — each with different technical literacy and different success criteria. This team navigated that stakeholder landscape as well as any vendor I have seen. They adjusted their communication register depending on the audience without losing the substance. They managed expectations honestly throughout. And they delivered a system that each group can point to as meeting their requirements. That breadth is genuinely uncommon.

PROS

Production system that has performed as specified since go-live without remediation work, documentation thorough enough to support internal maintenance, knowledge transfer that left our team genuinely capable

CONS

Pipeline availability for kickoff required a few weeks of lead time — in hindsight that selection pressure means you are working with a team that is in demand for the right reasons

Questions & Answers

Please describe your company, your role, and the industry you operate in.
As Chief Innovation Officer at Rheintal Digital AG I oversee technology investment and delivery across our Legal Services operations in Düsseldorf, Germany. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.
What specific problem or business challenge led you to hire this company?
Regulatory requirements in our Legal Services segment had changed and the compliance timeline was set by our regulator, not by us. The Mobile App Development changes required were significant enough to justify engaging a specialist partner rather than diverting our internal team from the product roadmap.
What services did the company provide for your project?
Primarily Mobile App Development, with adjacent work in solution architecture and quality assurance. They were responsible for the full build from requirements through to go-live, including integration with four existing systems in our technology landscape. The breadth they covered without requiring additional vendors was commercially and logistically valuable.
Why did you choose this company over other providers you considered?
The quality of the questions they asked during the briefing process was the first indicator. Vendors who ask precise questions in the sales phase tend to apply the same rigour during delivery. That hypothesis proved accurate. The technical proposal was substantive, the team structure was senior throughout, and the pricing was transparent.
How clearly did the company understand your requirements and business goals?
Extremely well, in part because they had relevant Legal Services experience that reduced the context-setting overhead significantly. They understood the domain vocabulary, asked the right questions, and translated business requirements into technical specifications with a fidelity that meant the development phase had very few clarification cycles.
How was your overall experience with their communication and project management?
Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between Düsseldorf, Germany and the delivery team. Written updates were specific and consistent, response times were same-day for anything that required a decision, and nothing fell through the cracks across a six-month engagement.
Did the company deliver the project on time and within your expected budget?
The project landed on time. The budget was managed within the agreed ceiling, which included one client-driven scope addition that was quoted fairly and handled without affecting the original delivery stream. The discipline around budget transparency throughout meant there was no surprise at invoice stage.
What tangible results or business impact have you seen since the project was completed?
Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the Mobile App Development work are meaningful: session duration up, conversion rate up, error rate down, and our NPS for the digital touchpoint has improved by eleven points. Our account managers report that the new capability is coming up positively in client conversations.
What did you like most about working with this company?
The willingness to be direct. When our requirements were unclear they said so. When our priorities were contradictory they explained why. When a technical approach we had assumed was the right one turned out to have significant downsides, they told us before we had committed to it. That kind of intellectual honesty is what I look for in a long-term technology partner.
Would you recommend this company to others, and would you work with them again?
Yes, without reservation. I have already made two direct referrals within my Legal Services network — in both cases to peers facing Mobile App Development challenges similar to ours. I gave those referrals with confidence because I knew the experience I described was reproducible, not the result of exceptional circumstances on our engagement.
