Takeaway Reality developed our custom software exactly according to the specifications we provided. We shared images and videos with them, and they transformed that into a VR platform where people can view their apartment or house. Users are able to explore the property through a fully virtual walk-through.

Mobile App Development Review from Marie-Laure De Veyt
We set out to build awareness around a new cyber safety product. After reviewing several agencies through an RFP, we chose TAR because they fully understood our objectives and had a clear plan to achieve them. From brainstorming to final execution, we collaborated closely and collected feedback in an organized way. Working with TAR has truly been an outstanding experience.

We were informed about every major step in the process and it really made everything much easier. Takeaway Reality’s work delighted the client. Their dedication to the project accentuated their deep and relevant knowledge of VR and AR. Their communicative and transparent approach resulted in methodical project management.

Software Development Review from Theodore Patestos
We’ve worked with Saad and his team for close to a year now. They’ve been diligent throughout the process, responsive and communicative. They came in mid-stream to save the project from another development team that didn’t live up to their commitments. I would highly recommend Plego to any company looking to see things move forward on a stalled project or looking for a team that will jump in and start to get things done.

Web Development Review from Tyler Tomlinson
Saad and his team were a great group of people to work with. Our scenario was probably unique to this group, and they tackled the project with a full head of steam and with no hesitation. It has been a pleasure working alongside his team.
