Slevin Reviews

Capable IoT Development team — happy with the end result

Siddharth Sharma / Co-Founder | Oct 19, 2026

We got a good result in the end, but the road there had a few bumps. 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.

We launched on schedule and have not had any major issues since. Their team changed one developer midway, which slowed things down for a couple of weeks. Happy to recommend them.

Project summary

Our company worked with Slevin to connect our equipment to a cloud dashboard so we could monitor it remotely. The work covered requirements, design, development, testing and launch support. We worked together for around 8 months.

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

We needed to connect our equipment to a cloud dashboard so we could monitor it remotely, and we didn't have the in-house capacity to do it ourselves.

What services did the company provide for your project?

IoT Development, plus QA and some consulting on how to structure the project.

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?

Yes, on time and within budget.

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.

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

Yes. They are a reliable IoT Development partner.

Solid delivery, though timelines needed some pushing

Heather Graham / Founder | Oct 15, 2026

The final product works well for us, although the process could have been smoother. They shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

The result looks great and performs well, and our internal team found it easy to take over. We had to follow up a few times on smaller bug fixes after launch. We are already discussing the next phase with them.

Project summary

Our company worked with Slevin 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. Overall it was a 4-month engagement.

Dependable Mobile App Development Partner for a Growing Financial Services Business

Nikhil Gupta / Head of Digital | Aug 20, 2026

The project went well overall. Their project manager kept things organised and was quick to flag anything that might affect the timeline. 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.

Since launch, everything has been stable and our team has adapted to it quickly. Estimates on a few features were optimistic and those took longer than planned.

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

Great Experience With Slevin on Our Software Development Project

Ananya Joshi / CEO | Jul 13, 2026

I would rate this engagement highly on almost every front. 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. 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 Software Development work has already made a noticeable difference — tasks that used to take hours now take minutes. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with Slevin to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 2 months.

Good results, communication improved as the project went on

Divya Iyer / Head of Digital | Jul 06, 2026

Overall the project was a success, though it was not without some challenges. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

We are already seeing better numbers than before the project. Their team changed one developer midway, which slowed things down for a couple of weeks. Overall, a team we trust and plan to keep working with.

Project summary
