If you need to redesign your website, I'd highly recommend working with Spritz. We felt their team really took the time to understand what we envisioned for our new site and used their skills and expertise to bring that vision to life. The whole process was very collaborative with open and responsive lines of communication throughout. We're super happy with the end result.

Worst media company ever!!! They never pick up their phone or return emails!!!! 4 months I have been calling them about a billing issue, and no response. I had to report them to the BBB to see if they can get a response from this company! Unprofessional, ignorant and just plain rude!! Do not use them!!!

Saucy Konfections's Review Sourced from Google
If you are looking to use this company, you may want to take a second to read over this review before you do so. This is one of the worst companies that i have worked with. In the beginning, it will seem great. They will tell all the things that you want to hear and you will sign a contract with them but BEWARE! Although you will sign a contract with them, they will not fulfill their end of their contract and at the end of the project, they will try to milk you for more money.Also, although the site is based in America, they hire people from China etc.. to do their work so although you will be shelling out American dollars, you are actually paying for someone in their house in India or China to do his/her job. All, in all, i was completely unsatisfied with the site that they did for me. Please feel free to reach out to me so i can tell you details and to show you receipts. I will even show you the contract! and how much money i paid for a project that really should have been half less than what i paid.I had to find others to clean up the mess this company made and the people that looked at my site said it was one of the worst that they have ever encountered!!!!Ps: I gave this company a “1” for effort…

Vention’s efforts allowed the successful development of the product, resulting in new customers. They provided backend developers, business analysts, UI designers, and QA testers to develop our solution. Vention cultivated a seamless partnership through constant updates and a collaborative approach. Overall, their team’s well-rounded expertise was impressive.
Web Development Review from AJ Canty
We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

So far so good. I am still waiting on an issue with Apple but I am excited for what they have created for my app idea. From Roman getting me started and connected with the development team to Safwan orchestrating the software, listening and making the changes I want. It has been a positive experience. They are flexible and do things in a timely manner. Can't wait until it finally gets released.

We engaged SolveIt to develop a minimum viable product (MVP) app, including a user-friendly iOS design, an artificial intelligence (AI) model, and a monetization strategy while ensuring General Data Protection Regulation (GDPR) compliance and preparing for future integrations. Despite a tight deadline, SolveIt delivered the app on time and efficiently handled beta-testing within three months, allowing us to gather feedback and launch successfully. We acquired our first 1,000 users within a month of launching the app. SolveIt's team communicated effectively, addressed issues proactively, and maintained a high level of autonomy, bringing diverse expertise that greatly benefited our project.

Junkies Coder delivered an excellent mobile app for BPI Real Estate Poland, combining strong technical skills with a clear understanding of our business goals. From the start, they were professional, responsive, and focused on user experience. The app was designed with a clean, modern interface that made property browsing, filtering, and agent contact smooth and intuitive. Built using React Native, it launched seamlessly on both Android and iOS platforms, with features like advanced search, map integration, push notifications, and bilingual support. The team managed the project efficiently using agile methods, kept us informed with regular updates, and quickly implemented feedback. They also ensured strong backend integration with our property database and CRM. Testing was thorough, and the final app was stable, fast, and secure. Since launch, we've seen a noticeable increase in user engagement and property inquiries. Junkies Coder also provided great post-launch support, helping us refine features and monitor performance.

Web Design Review from Gregory Kohs 📊
ISKPRO did a really nice job, right from the point of initial contact, through to the point of final deliverable -- plus they made a couple of follow-on recommendations for additional work that could benefit my business. But no "hard sell" on those items. Just how I like it. The team was especially patient with me, because due to some unforeseen interruptions to my schedule, I was not very prompt in keeping the project moving. But they patiently waited at ISKPRO, and I was not charged for any of these delays that I caused (even though I'm sure it was somewhat disruptive for their developer).All in all, a great job -- and their fees were about 60% less than what a local agency would have charged me to do the same work!

Silicon Valley has become a synonym for tech innovation. Despite its rather extravagant standard of living, San Francisco is a magnet, attracting young entrepreneurs and engineering talent alike.
Forbes ranks San Francisco the tenth best city in the US for business and careers (18th if you count cities with a population below one million residents) so it’s not surprising that it houses more than twelve Fortune 1,000 companies including ABM, Levi & Strauss and more.
San Francisco (and the vicinity) is a home to technology giants like Apple, Twitter, Yelp, Uber, Zynga, Pinterest, Dropbox, Airbnb and Google which contributes to Golden City being considered the tech capital of the world.
This is why app developers in SF are known around the globe for their creativity and expansive software knowledge capacity that allows them to deliver some of the most innovative and high-performing applications in the world.
App developers tapped into San Fran’s long history of established companies in the business and professional services sectors and partnered with local clients including 1900+ tech companies, 120+ biotech companies and 200+ cleantech companies.
This is why they are uniquely positioned to create successful apps for both local and clients across the country.
San Francisco app developers are highly skilled in crafting multi-purpose mobile applications for various platforms. Their job is to understand their client’s needs and goals and then morph their unique ideas into tangible software products that solve specific problems or unmet need.
