Exceeded our expectations on quality and communication

Mark Sullivan / Director | Oct 03, 2026

Welf Lab did an excellent job for us. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

The IoT Development work has already made a noticeable difference — tasks that used to take hours now take minutes. Overall, a team we trust and plan to keep working with.

Project summary

We partnered with Welf Lab to set up a sensor network and alerts for our cold storage facilities. The work covered requirements, design, development, testing and launch support. Overall it was a 6-month engagement.

Questions & Answers

Please describe your company, your role, and the industry you operate in.

I'm the Director at Keystone Life Sciences, a Pharmaceuticals & Biotechnology company based in Chicago, USA. I look after our technology and work closely with outside partners on bigger projects.

What specific problem or business challenge led you to hire this company?

We needed to set up a sensor network and alerts for our cold storage facilities, and we didn't have the in-house capacity to do it ourselves.

What services did the company provide for your project?

Mainly IoT Development. They also helped with the technical planning and a few integrations with our existing tools.

Why did you choose this company over other providers you considered?

We compared three or four agencies. Welf Lab asked the best questions and had good reviews from past clients.

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

Better than we expected. They pointed out a few things we had not thought about.

How was your overall experience with their communication and project management?

Good. Weekly calls, regular updates and a shared board meant we always knew where things stood.

Did the company deliver the project on time and within your expected budget?

Yes. The only extra cost came from features we added ourselves, and they quoted those fairly.

What tangible results or business impact have you seen since the project was completed?

It is still early, but the numbers are trending in the right direction and the system has been stable.

What did you like most about working with this company?

The consistency. Same team, same standard, from the first week to the last.

Would you recommend this company to others, and would you work with them again?

Yes, I've already recommended them to a couple of people I know.

Great Experience With Welf Lab on Our Mobile App Development Project

Kevin Carter / Product Manager | Sep 03, 2026

Welf Lab did good work for us, and we would use them again. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They shared working builds regularly, so we could test early and give feedback before things were locked in.

We are already seeing better numbers than before the project. There were some early misunderstandings on requirements that took a few rounds to sort out.

We are already discussing the next phase with them.

Project summary

Our company worked with Welf Lab 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 3-month engagement.

Great Experience With Welf Lab on Our IoT Development Project

Felix Richter / Owner | Aug 13, 2026

The project went well overall. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

It has made a real difference to how our team works day to day. A couple of milestones slipped by a week or so, mostly around testing. I would recommend Welf Lab to anyone looking for a dependable IoT Development partner.

Great Experience With Welf Lab on Our AI & Machine Learning Project

Ben Doyle / Operations Manager | Jul 06, 2026

The project went well overall. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

We launched on schedule and have not had any major issues since. Documentation at handover was a bit thin and we had to ask for more detail. Happy to recommend them.

Project summary

Welf Lab was brought in to build a demand forecasting model on top of our sales data. They also took care of integrations with a couple of third-party tools we already used. The project took roughly 5 months from kickoff to launch.

Good work overall, with a few bumps along the way

Maria Henderson / Director | Apr 16, 2026

The final product works well for us, although the process could have been smoother. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

We launched on schedule and have not had any major issues since. A couple of milestones slipped by a week or so, mostly around testing.

We are already discussing the next phase with them.

Quality work, a little slower than we planned

Nathan Kelly / VP of Engineering | Apr 12, 2026

Overall the project was a success, though it was not without some challenges. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They shared working builds regularly, so we could test early and give feedback before things were locked in. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

It has made a real difference to how our team works day to day. There were some early misunderstandings on requirements that took a few rounds to sort out. Overall, a team we trust and plan to keep working with.

Project summary

We partnered with Welf Lab to add an AI chatbot to our support site that answers questions from our help docs. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 9 months.
