As a growing business in Australia, our internal systems had become difficult to manage. We partnered with SDLC CORP for Odoo development, and their team took the time to understand our workflows and bottlenecks.

HatchWorks AI Reviews & Testimonials

Software Development Review from Ryan Husk
HatchWorks developed a solution to automate calculations for our sales team. The company created an application with a user-friendly interface and scalable algorithms in Python. HatchWorks had similar experience in the healthcare industry and we were satisfied with their responsiveness, QA, communication, and ability to translate imagination into actionable tasks. The project was well-organized with clear expectations and deliverables, making it easy to address miscommunication.

Software Development Review from Shaun Bank
HatchWorks was hired to develop custom software for a hybrid app and rebuilt the front-end. They provided top talent in LATAM and adapted to end client's changing needs. Despite rate fluctuation, they performed well, met commitments, received positive feedback and maintained high level of quality output and professionalism. The team coordinated effectively and the nearshore model is becoming more popular. The consulting firm was happy with HatchWorks' velocity and code quality.

Digital Strategy Review from Meishelle Haverkamp
HatchWorks is always a true partner that consistently delivered results. They completed several market analysis projects for us analyzing the competitive landscape and provided recommendations for strategic growth and growth opportunities. We have a long-standing relationship with Hatchworks. They have done several market analysis projects for us & always are able to synthesize large amounts of data into a compelling & easy to understand story.

Highland Reviews & Testimonials

UI/UX Design Review from Audrey Thomas
Highland is a great partner. The sought to deeply understand our product, customers, and pain points and built a number of forward looking opportunities for us in addition to the tight scope of our project. Proactive, thoughtful, responsive, and flexible. We are a small team and found lots of value in working with Highland to get our UX refresh project up and running.

UI/UX Design Review from ✨ Liz Pisney ✨
We recently partnered with Highland on research and prototypes for a new information architecture on a volunteer resources site for our Chapter leaders. Having over 3000 volunteers around the globe can introduce a lot of nuance and complexity to research and design processes. The team at Highland handled it all skillfully - focusing on how to deliver the most clarity and usability to our audience. 10 out of 10, I would recommend working with the Highland team!

Webflow Review from Lee Wiensch, CAE, CFRE
We had a great experience working with the team at Highland to develop a new website for the Thoracic Surgery Foundation, a charitable organization aimed at advancing heart and lung health for all. Highland worked with us to re-imagine a dated website with limited functionality, and developed a a gorgeous new site that beautifully reflects the vitality of the organization. We anticipate that our award applicants, donors, surgeons and grateful patients will be able to easily navigate the new site and have a much-improved user experience. Jeff Blanchard and his team were exceptionally good listeners, and worked hard to create solutions for our complicated awards program. They provided good training to our team throughout the process so that we have been able to keep things updated and easily make changes now that the site has launched. I am grateful for their patience and very quick turnaround as we juggled a new strategic plan and new branding, all at the time of the website creation. I have been continually impressed with the expertise and the innovation that Highland brings to a project like ours. It was a pleasure to launch this site -- on time and on budget -- with their excellent work and support.

Material Hauling's Review Sourced from Google
I was referred to Esco Logics by a business associate when we were ready to create our very first website. I’m so glad I was connected with this company. Shariq and his team were absolutely EXCELLENT to work with! They brought our vision to life exactly how we imagined it and were always available, responsive, and quick to address any questions or concerns. They were also extremely adaptable to changes along the way. I will gladly recommend Esco Logics to anyone in need of web services and look forward to working with them again.
Tom McGovern's Review Sourced from Google
Hi, my name is Tom, and I’m the owner of Custom Equipment Company. I’ve been in business for over 40 years, and I knew early on that having a strong web presence was essential.I’ve worked with Escologics for more than 15 years, and from day one, they’ve been the perfect partner. I needed a team that truly understood e-commerce—not just the technical side, but also how to create a site that actually sells. Escologics delivered on both.They built a site that’s fast, easy to navigate, and designed to grow with my business. Over the years, they’ve guided me through design updates, new features, and the latest integrations, keeping my site competitive and my customers happy.Anytime I faced a challenge—whether with online sales, security, or user experience—Escologics had the right solution. Their team has consistently gone above and beyond to make sure everything runs smoothly.Looking back, I can’t imagine achieving the same level of success without them. If you’re looking for a partner who truly cares about your business and has the expertise to help it thrive, I can’t recommend Escologics highly enough. They’ve been invaluable to my success.
