Software Development Review from Daniel Gonsenhauser
Unico built our Order Management System across two operating companies and integrated it with Bringg for dispatch. The hard part wasn't the software, it was the business logic we run on-demand, multi-stop, scheduled contract, and distribution work across multiple markets, and the pricing exceptions that used to live in our people's heads are now configured in the system. Order intake, dispatch, commissions and billing are one flow instead of three, and our team reviews work rather than reconstructing it. What set Unico apart was their willingness to learn how a courier and freight business actually operates instead of fitting us to a template. We worked with a dedicated team on the Unico side - a project lead, developers, and QA with direct access throughout rather than everything routed through an account manager. We've engaged them for phase two.
Web Development Review from Shifa Sutar
We had a great experience working with Unico team for our Google Workspace migration and account setup. The entire process was smooth and well-managed. The team was extremely supportive, responsive, and guided us at every step, making what could have been a complex transition feel effortless. Highly recommend their services.
Website Redesign Review from Heta Patel
We engaged with Unico for website design and front-end coding for the same. It was a good experience overall. Initially we faced some issues which were resolved and the team mates for coding were great, had good knowledge and were able to deliver as per our expectations.

Equally, they built with minimal reliance, considering easy adoption by our developers when selecting a tech stack.

Software Development Review from Ismeet Kaur
I recently had the pleasure of working with Grawlix on developing a custom staffing management software for my company, and I couldn't be more impressed with their comprehensive approach and exceptional service. From the very beginning, Grawlix excelled in gathering our requirements, ensuring they thoroughly understood our unique needs and pain points. Their team was highly communicative, providing insightful recommendations that helped refine our vision. The development phase was marked by a seamless integration of our specifications into a user-friendly and efficient platform. Grawlixs attention to detail was evident in every aspect, from the intuitive design to the robust functionality of the software. As we moved towards the launch, their support was unwavering, addressing any last-minute adjustments with professionalism and speed. The final product exceeded our expectations, streamlining our staffing processes and enhancing overall efficiency. Grawlix delivered not just a software solution but a transformative tool for our company, and I highly recommend their services to anyone seeking top-notch staffing management solutions.

Dustin Wheeler's Review Sourced from Google
it was such a pleasure working with App Founders and just how easy and professional they were. I quickly realized how the industry is full of thirsty, needy bots and scammers I’m trying to get your attention, but tons of unsolicited phone calls and texts. Dealing with these guys was a breath of fresh and definitely showed up in value above all the rest.
Munna Alam's Review Sourced from Google
Got to say, The App Founders really impressed me! They totally nailed the design for my mobile game. Can't wait to team up with them again to make and promote the game. Definitely recommending them to anyone looking for top-notch game development services!
berry paul's Review Sourced from Google
The App Founders is able to develop console games and deliver them on time. I have worked with them for a year now and they have never missed a deadline, which is important to me as a developer. The team is friendly, knowledgeable and always willing to help if you need anything.

Came across these folks at the Logan Sq Farmers Market and am glad I did. Delicious, healthy snacks. Love supporting a business that gives employment opportunities to individuals with disabilities. Highly recommend checking out Fueled by AF!
Savannah Visor's Review Sourced from Google
I bought a variety pack of protein bites from the Made in Chicago Market. They taste really good and have a nice amount of protein. The chocolate chip cookie dough and fudge brownie are my favorites. The serving size is 3 seperate bites, but I was satisfied after 2. They are a great snack! If I’m just a little hungry and want something a tad sweet it’ll be great to just grab one from the fridge.

Came across Fueled by AF at the Elmhurst Farmers Market, big fan of their mission and these maple pecan protein bites!

1 2's Review Sourced from Google
We hired flexsin technologies to build software for us in July 2022. They agreed to sign NDAs and all relevant paperwork. They prepared the NDA as they preferred it and sent it to us for review and signature. We reviewed the NDA and changed the Jurisdiction to UK and sent it back to them for a signature which they delayed in signing up to date. After they reviewed everything, they gave us an estimation of USD 17,000. They sent us a contract with upper price cap stating that any extra activities and costs incurred above the agreed upper price cap will be their responsibility and we as the client will have to pay nothing extra. They estimated the project will take 12-14 weeks. They started the project and assured us the NDA and Contract is getting sorted and they will send it over as soon as. Long story short flexsin Technology never honoured the contract and the price cap as the price started increasing past the price cap. It is now been 8 months since they started the project and they have not signed the NDA nor the Contract as agreed. We noticed they misspelt the names on the NDA and Contract. We asked them to rectify the spelling mistakes and they have refused asking us to Change the NDA that they wrote themselves to meet their interests. They are asking us to include on the NDA that UPwork will resolve disputes in relation to incorrect spellings on the paperwork and the NDA as if they are planning to make more mistakes. Up work is just a platform that brings developers and clients together, UPwork does not resolve spelling mistakes and unsigned paperwork. UPwork is NOT developing our software for us, we did NOT share the software information with UPwork, we shared information with Flexsins Technologies and above all Up work did NOT misspell or fail to sign the NDA or Contract, that was Flexsins Technologies mistakes to fix and NOT UPwork mistakes to fix. They are now asking to write another contract for more money probably with another price cap just to lure. They have agreed to send the assets back to us immediately. Updates of this review to follow on here, twitter, LinkedIn, IG, TikTok, and any other platform.
Liam Durbin's Review Sourced from Google
I have had a great experience with Flexsin. My small business is a bit of a niche (horse racing) but the team at Flexsin worked very hard to understand the nuances. Very impressive breadth of skills on the team. The support work they do for my small business on a monthly retainer has been good, as has their project work on a mobile app.
Dave Reynolds's Review Sourced from Google
I've been with Flexsin for 3 years now, and it's a great place to work. Talented technical staff and good management. After years of providing IT staffing solutions for US based companies with local personnel, I'm now able to save our clients a LOT of money by using the resources of our talented team of resources at our offshore development center instead.
