Delivered on time and stayed involved after launch

Johan Botha / Director of Technology | Sep 12, 2026

We were very happy with how this project went. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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.

We launched on schedule and have not had any major issues since. We would definitely work with them again.

Project summary

Our company worked with TJ Labs to add an AI chatbot to our support site that answers questions from our help docs. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 7-month engagement.

Questions & Answers

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

Westbridge Properties (Pty) Ltd is a Real Estate business in Durban, South Africa. As Director of Technology, I was responsible for this project on our side and the main contact for TJ Labs.

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

We had tried to do this internally and it stalled. We needed specialists to add an AI chatbot to our support site that answers questions from our help docs.

What services did the company provide for your project?

Mainly AI & Machine Learning. 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?

Their pricing was fair and they were honest about timelines instead of just telling us what we wanted to hear.

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?

Mostly. One milestone slipped by about a week, but the final delivery was on schedule and the budget held.

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

We can now handle more volume without adding staff, which was the main goal.

What did you like most about working with this company?

Their attention to detail and the quality of the final product.

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

Yes, I would recommend them and we plan to work with them again.

They listened, asked the right questions, and delivered

Amit Nair / CEO | Sep 06, 2026

Our experience with TJ Labs was really positive from start to finish. 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We would definitely work with them again.

Project summary

TJ Labs was brought in to develop a field-staff app with offline mode that syncs back to our main system. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 3 months.

Professional team that made a complex project feel manageable

Nikhil Verma / Founder | Jun 05, 2026

TJ Labs did an excellent job for us. 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Since launch, everything has been stable and our team has adapted to it quickly. I would recommend TJ Labs to anyone looking for a dependable IoT Development partner.

TJ Labs Delivered a Quality AI & Machine Learning Solution on Time

Rachel Ng / Co-Founder | Apr 07, 2026

TJ Labs did an excellent job for us. They shared working builds regularly, so we could test early and give feedback before things were locked in. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

We are already seeing better numbers than before the project.

Happy to recommend them.

Project summary

We partnered with TJ Labs to automate document data extraction that our team was doing by hand. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 3 months from kickoff to launch.

Great Experience With TJ Labs on Our IoT Development Project

Noura Saleh / Project Manager | Feb 27, 2026

The project went well overall. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Since launch, everything has been stable and our team has adapted to it quickly. Their team changed one developer midway, which slowed things down for a couple of weeks.

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

Project summary
