They listened, asked the right questions, and delivered

Sanne Jansen / Founder & CEO | Aug 29, 2026

We were very happy with how this project went. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We are already discussing the next phase with them.

Project summary

We partnered with William to build iOS and Android apps for our customers, including booking, payments and push notifications. The work covered requirements, design, development, testing and launch support. The project took roughly 7 months from kickoff to launch.

A reliable long-term partner for our tech needs

Marcus Lim / Senior Product Manager | Aug 14, 2026

Overall we had a good experience working with William. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Their project manager kept things organised and was quick to flag anything that might affect the timeline. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. A couple of milestones slipped by a week or so, mostly around testing.

If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with William to rebuild our existing mobile app, which had poor reviews and frequent crashes. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 5 months.

Solid delivery, though timelines needed some pushing

Faisal Al Zahrani / CEO | Jun 28, 2026

Overall the project was a success, though it was not without some challenges. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We launched on schedule and have not had any major issues since. Estimates on a few features were optimistic and those took longer than planned. We would definitely work with them again.

Project summary

Our company worked with William to build iOS and Android apps for our customers, including booking, payments and push notifications. They worked alongside our in-house team, which mostly handled business requirements and testing. Overall it was a 9-month engagement.

Exceeded our expectations on quality and communication

Maria Patel / Senior Product Manager | Jun 16, 2026

The project went well overall. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The Web Development work has already made a noticeable difference — tasks that used to take hours now take minutes. A couple of milestones slipped by a week or so, mostly around testing. Overall, a team we trust and plan to keep working with.

What services did the company provide for your project?
End-to-end Web Development — from requirements and design through to deployment and a support period afterwards.
Why did you choose this company over other providers you considered?

How clearly did the company understand your requirements and business goals?

Good work overall, with a few bumps along the way

Lucy Harding / Owner | Jun 04, 2026

Overall the project was a success, though it was not without some challenges. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The result looks great and performs well, and our internal team found it easy to take over. Their team changed one developer midway, which slowed things down for a couple of weeks. We are already discussing the next phase with them.

Project summary

Our company worked with William to develop a field-staff app with offline mode that syncs back to our main system. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 5 months from kickoff to launch.

Quality work, a little slower than we planned

Huda Al Otaibi / Founder & CEO | Apr 19, 2026

We got a good result in the end, but the road there had a few bumps. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They shared working builds regularly, so we could test early and give feedback before things were locked in. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We are already seeing better numbers than before the project. Documentation at handover was a bit thin and we had to ask for more detail.

If you need a team that communicates well and delivers, they are a good choice.

Project summary

We engaged William to automate document data extraction that our team was doing by hand. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 5 months.

Great team to work with — professional, responsive and reliable

Saud Al Qahtani / Head of Digital | Apr 11, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline.

The result looks great and performs well, and our internal team found it easy to take over. We are already discussing the next phase with them.

Project summary

We partnered with William to add an AI chatbot to our support site that answers questions from our help docs. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 6 months.

Delivered on time and stayed involved after launch

Emma Thompson / Director | Apr 05, 2026

We were very happy with how this project went. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

It has made a real difference to how our team works day to day. We would definitely work with them again.

Good value and a team that genuinely cares about the result

Kelly Miller / IT Manager | Feb 21, 2026

Our experience with William was really positive from start to finish. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

FAQ

Frequently Asked Questions
