      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.

      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.

      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.

      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.

      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.

      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.
