Software Development Review from Michael S.
We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

Software Development Review from Michael Levy
Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

Software Development Review from Jane Smarovozova
We collaborated with K-Optional to develop a custom inventory management dashboard tailored for real estate clients. We provided the creative vision and detailed designs, while their team focused on the software development, ensuring that every element was implemented perfectly. We worked hand-in-hand flawlessly, resulting in a sleek, user-friendly interface that not only looks great but functions seamlessly. The synergy between design and development allowed us to deliver a product that exceeded client expectations, combining aesthetics with powerful functionality.

Phenomenal team to work with. From Sales to Engineering, Customer Service and at the highest level of leadership, the DualBoot partner team is simply great.They are consistent and interested in your success. Once their engineering team has learned your stack, you can't tell from inside to external resources. Work just gets done. I recommend them w/o reservations; start-up or well established firm, you are in great hands with the DualBoot team!

Absolute crap company, I'm currently filing a lawsuit against them for defamation because they like to tamper with things on the website and are resentful little children. They give you attitude when you asked for what you purchased. Struggle to get my domain and are deleting reviews after I got it.

Yolanda Torres's Review Sourced from Google
RUN AWAY from this company! Supposedly located in California. They sold me a package to design the branding, website, and social media for my company for $1500.00. "EVERYTHING" for $1500.00. Have paid over $6000.00 and I have NO control over the material I paid for. They send you everything in formats you cannot use or convert. They want to keep a hold of you to keep asking for money!!!!!! NEVER send anything to print through them!!! Ordered some business cards and brochures and have never received the brochures. To this day I have not received a single invoice or receipt of anything of what I have paid, including the design of the logo, the purchase of the domain and many other things. DO NOT RECOMMEND.

David McCurrach's Review Sourced from Google
I believe this company is a criminal enterprise. They are also known as Creative Company and Sketch Profs. Creative Company made a $2,500 unauthorized withdrawal from my checking account. When I protested the transaction, Uptown Logo Design provided a fake receipt, fake transaction and activity logs and fake emails supporting the charge to my account. It was an elaborate and thorough fraud. I'm sure they've used similar fabricated documents before with other people they've ripped off. I reported them to the FTC and FBI.

Michael Garrity Review from Google

Michael Garrity's Review Sourced from Google
Our ecommerce business has now worked with LaunchPad Lab on two major website redesign projects. The first one allowed us to completely rebuild our site from scratch. They built us our own unique ecommerce management system that gives us greater flexibility than the popular "out of the box" platforms. For most companies our size, these pre-built systems are the only thing available. This upgrade provided a huge boost to our business, making our website more agile and responsive to the needs of our customers. It grew our business by nearly 300% over the course of around 3 years. When we wanted to refresh the look of our site and add more functionality to improve the user experience, it was a no-brainer to return to LaunchPad for help. Like us, their company had grown in the last few years, and this time around, we were equipped with a full-service team of designers, developers, and online optimization strategists who have not only helped improve our website's design and performance, but also shared their years of expertise with us to help us better understand our own goals and how to make smart decisions about what's best for our company and our customers. LaunchPad's detail-oriented approach to their work has helped us get better at making big picture decisions the have long-term money- and time-saving benefits for our business.

Would avoid at all costs. We spent $200K to develop a software that after one year there own team could not upgrade to work with Salesforce. If you disagree with them they will turn you over to collections without hesitation and no basis. The CEO Scott will then brag that he is an attorney and there is nothing you can do about it. Think twice, there are lots of software companies out there.

Bradley Collins's Review Sourced from Google
Working with the guys at Espresso Moon (Scott, Doug, Tim and Dwayne) was truly a great collaboration and experience. They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen. If I were to recommend a web design/hosting company to anyone, Espresso Moon would be the one and only name I give. Thank you for your service and support!

Meredyth Jones's Review Sourced from Google
I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.

Caleb Schallert's Review Sourced from Google
Doug Wheeler is the owner of Espresso Moon and he has provided my small business excellent IT technical support for our website. His team helped me out by removing malicious code that was affecting my site right after the Heart Bleed epidemic last year. He got my site back up and running so i could continue business and save my online reputation. I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget. They are truly a pleasure to work with!
