HDWEBSOFT Reviews & Testimonials

Web Development Review from Jason Harvison
HDWEBSOFT did a fantastic work that aided the client in expanding their business, particularly in terms of growing website subscriptions. The project began on schedule and opened up a lot of opportunities for the business.

Web Development Review from David Zalik
Using a smooth user interface, HDWEBSOFT effectively updated our landing page, enticing visitors to sign up for the product's waitlist. The staff provided a customized strategy and was incredibly responsive, driven, and enthusiastic. They also used ClickUp for project administration.

Mobile App Development Review from Max Levchin
We've partnered with HDWEBSOFT who have created our app using .NET. The feedback from our customers we've received has been overwhelmingly good. We had heard positive things about the idea even before we released the app, so it's encouraging to see those comments continue once it has been out. HDWEBSOFT was set up from the start. The design team was outstanding; they completed the job on schedule and within our allocated budget. They followed a well-defined procedure that was in place.

Revelation Agency Reviews & Testimonials

Branding Review from Marta Stattmiller
A friend referred me to Revelation after they had helped them with their healthy snack brand. We were looking for an agency that would take our idea and design it into a brand that really stood out from the rest. We felt the Revelation group did a great job with all of the branding and marketing brief creation along with guiding us on how to stand out in our space.

Branding Review from Christopher Hiti
We have worked with Revelation on a few branding projects, and they have always delivered on time and with a great sense of creativity. Their team understands market positioning well, and is one of the reasons we continue to utilize them for all things branding and creative.

Web Design Review from Guisou Akhavan
After searching for a few months for a creative agency I ended up going with Revelation, I felt they understood my goals the best along with having a distinct design language. I was pretty impressed with the direction they took on my branding materials and web design project and feel comfortable recommending them to other people needing similar services.

Email Marketing Review from Rida Khan
This is the second company I've worked with Grazitti at and both experiences have been positive. Their team is able to turn around our requests very quickly and has provided good best practices from their work with other clients. I'd recommend them for the Marketing services.

Web Design Review from Patricia Lughezzani
Grazitti and Marketo Support have successfully partnered to roll out rich functionality and support Portal. Beyond core development skills to implement business functionally in SFDC Service Cloud and Customer Community, the Grazitti team has been a valued contributor to recommend technology such as Solr text search, workflow optimizations, and web creative design.

Digital Marketing Review from David Skyberg
Right from start the Grazitti team gave us the confidence that we do not need to have a plan B. Once things started rolling – they were able to accommodate a number of requirements that were made by the operating teams within the timeframe.

AI Development Review from Eyüp Tekece
We run a few e-commerce brands on markets where there are not much analytical tools to plan launch of new products. Building a few agents to close the gap and let us launch new products more predictably way.
Andrij Chornejko's Review Sourced from Google
The avatar pronunciation tool they built is mad. TTS with emotion and lip-sync so learners can actually see how to shape their mouths for English sounds. The avatar’s facial expressions carry the tone—it’s not just a flapping mouth. Our language students retention jumped 30%. No cap these folks understand the little things.
Mr Garry's Review Sourced from Google
We brought Litslink in to build RIV — a GPT-powered AI task planning assistant for our product management team. Before the engagement, our PMs were spending 30–45 minutes per request manually rewriting briefs into Jira tickets, and risk blind spots kept surfacing after deadlines had already slipped.Litslink designed a three-pipeline AI system covering task decomposition, risk prediction, and named entity extraction — all integrated directly with our existing PostgreSQL stack and Jira workflow. The NER layer now auto-fills 90%+ of date, tag, and assignee fields, which alone eliminated hours of repetitive copy-pasting across Slack, Notion, and Jira.The results were measurable: task decomposition is now 60% faster, and each PM recovers roughly 8 hours per week. The Scrum-based delivery was transparent throughout — two-week sprint demos surfaced edge cases early, and the team iterated quickly based on real PM inputs.Delivered on schedule and within budget. Post-launch support and prompt refinements have been proactive. Solid technical partner for AI-driven workflow automation.

The App Founders Reviews & Testimonials
Walter White's Review Sourced from Google
Initially, The App Founders showcased a pro-found grasp of blockchain technology and its practical applications. They adeptly elucidated intricate concepts in a manner that resonated with my non-technical background, facilitating smoother communication and active involvement in developmental discussions.
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!

Nathan Dyer's Review Sourced from Google
As a result of our engagement with Bluelight Consulting, we are saving hours of developer time every week. We are able to deploy several times a day to multiple environments and going forward we’re going to better position ourselves as a company that offers tools that provide timely solutions for our internal users, which is what we pride ourselves on. There has been a tremendous lasting effect without a doubt. They meet set timelines within budget, keep clear communication lines, and are more than ready to address any emerging issues in a timely fashion. You can sense a sincere desire to meet our needs to the letter. It makes a huge difference. I must say we’ve worked with other vendors before where their ego was much bigger than working with us.
Emily Lien's Review Sourced from Google
Our cooperation with Bluelight Consulting worked out very well. Their experts find the right solutions for various problems, they work quickly, provide the right people for each job, and offer valuable suggestions on how to improve the product. Their flexibility and ability to adjust to our situation was the most important factor for the success of the project.
David McCulloh's Review Sourced from Google
After a thorough search for the best DevOps-as-a-Service companies in the US, and based on testimonials from past clients on their website, we felt the Bluelight Consulting team was the right choice to collaborate with on this project. And from the moment we booked a discovery call with them, we knew we had made the right choice. Thank you Bluelight Consulting!
