      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.

      Daniel Avitia's Review Sourced from Google

      OK, heads up, this is a long review. For those of you who don't have the time to read this:Citrusbits is the best iPhone app development company you'll find in Los Angeles. They were friendly, creative, professional and methodical in their procedures. These guys are the real deal.I began my app development working with an overseas team I found on freelancer. I thought the language barrier wouldn't be a big issue but I was wrong... way wrong. The final product I received from these guys was downright awful. Did it complete the functions I wanted it to? Yes. Was I eager to show it off? Definitely, no.I decided that if I was serious about my idea, I would need to work with a professional mobile app developer close to me in Los Angeles. I called numerous places, sat down with multiple companies and finally found my home with Citrusbits. Most companies felt a bit cold and robotic but Citrusbits seemed to just get it. They took the time to absorb my idea and gave me some great feedback right off the bat. I really felt they were on my same wavelength.Once I signed the contract, things were moving quickly. The difference between working with a team overseas and working with Citrusbits right here in Los Angeles was clear right away. I had no idea how much detail went into just the planning of an application. They came up with so many additional points and details that I didn't even think of. I knew I picked the right team.Design was the most fun for me. I had multiple options to choose from. Each completely different in terms of colors, icons, font and overall feel. They literally took the idea out of my mind and transformed it into something tangible. I could see my dream becoming a reality.Programming was a breeze. I tested each release with the team in Los Angeles. Working out the bugs was never tedious, always fun. I really felt as though I was part of the team, not just a client.Everything went so smoothly. We've started development on version 2.0 of the application now. I'm happy to call Citrusbits my very own Los Angeles development company.

      Communication and enthusiasm are big parts of making a team work well. Citrusbits has really impressed me with how they've jumped right in and really worked hard while always making sure that I was part of the process. If all goes well, I'll be back for more apps!

It also had to integrate with Amazon Web Services (AWS) to ensure stable and secure control over workloads.  
  • Solution: Vention assembled a dedicated team to develop the virtual platform according to the client’s requirements. It also deployed a multi-account AWS system that enabled Dialogue centralized access and control over workloads 
  • Results: Vention reduced the latency of heavy queries from 1 minute to less than 30 milliseconds. As a result, Vention became a key development partner for Dialogue, which has since grown into one of Canada’s largest telemedicine companies that supports millions of users across 25,000+ organizations. 

How do I choose the best startup software development company for my business?

To choose the best startup software development company for your business, follow these steps: 

  1. Define your project’s goals 
    Clearly outline your software’s key features and unique selling points. You should also have at least a basic idea of the target audience your software is meant for. 
  2. Set your budget 
    Determine the money and resources you will allocate for the project. This includes the licenses for the tech stack and maintenance and support fees.  
  3. Research prospects 
    Start your search on Google and agency directories like DesignRush, which organize development companies according to specializations and have in-depth profiles. You can also ask colleagues in your industry for recommendations. 
  4. Conduct interviews  
    Once you have a shortlist of five prospects, call each one and schedule an interview to discuss your project. 
  5. Assess expertise 
    Ideally, the agency should be experienced in your industry or similar fields. Request for a portfolio, case studies, and team members' credentials so you can assess their capabilities and the quality of their work. 
  6. References and reviews
    Ask for references from their previous clients, particularly those within your industry, to gain insight into how they collaborate with partners. Google My Business and online directories like DesignRush can also provide transparent client testimonials. 
  7. Communication and collaboration 
    Ask the company how they will ensure constant and transparent communication during the project and whether they can collaborate closely with your team. If team members are working in different time zones, ask how they will be coordinated to ensure alignment with the project’s progress. 
  8. Cultural fit 
    Ensure the company’s values and work environment align with yours. A cultural mismatch could lead to friction amongst team members, impacting morale and overall productivity. 
  9. Send an RFP 
    The request for proposal (RFP) should contain your project’s goals, timeline, and allocated budget. If the agency will be given access to sensitive company and customer information, include a non-disclosure agreement. 
  10. Negotiate terms 
    Ensure the agency is aware of your expectations and the deliverables they must provide at the end of the project. You must also be clear about the services you require and are willing to pay for. 
  11. Select a partner 
    Choose a startup software development agency that matches your project’s requirements.
