    • John Laporte
      John Laporte Founder at Vets on Point
      5.0★

      Mobile App Development Review from John Laporte

      Designli helped us define the requirements, features, and user experience for an app for our motorcycle organization. They produced technical documentation and a clickable prototype covering navigation, member tools, and safety features. They were responsive, delivered on time every time, and turned our broad concepts into something people could actually click through. The prototype got our stakeholders aligned, earned internal approval, and set us up for engineering, and working out design questions early should save us rework later.

      5.0★

      Mobile App Development Review from Brandi Heffner

      Designli built our SaaS product from scratch, using AI to speed up development, with AWS and Cloudflare in the stack, and they also handle our hosting and maintenance. We had a working MVP in just 30 days and have kept adding features since. In the first 60 days they went beyond what we expected, largely because they took the time to really learn our business and our market. Coordination through Basecamp and Google Meet has kept everything organized.

    • Thomas Simmons
      Thomas Simmons CEO at Simmons Driving School
      5.0★

      Mobile App Development Review from Thomas Simmons

      Designli took over app development and marketing for our driving school, with the goal of building a product we could eventually offer to other schools. Within two and a half months, the app was up and running in our own school. Their project management is excellent, and they push back constructively, thinking through what we actually need instead of building every request as-is.

      Scott Bohning (RockerNJ)'s Review Sourced from Google

      As a developer, working with the UX Team was always smooth sailing. Their UX is tight and clean, never any unrealistic "if this, then that". I can give them their own branch, and they check it back in with all of the assets I need in order to develop the project. Always properly formatted and well comments. No time wasted on "spaghetti code". After working on multiple projects with the UX Team, I can say I HIGHLY recommend them!

      Mike Benyo's Review Sourced from Google

      The UX Team is amazing. High-end professionals, they are really experts in all aspects of UI and UX. Chris and the Team were able to immerse themselves in our complex product environment and develop a Design System and screens that completely exceeded our expectations. They went beyond just the user interface, and actually thought about the key functionality in new ways. And even came up with new monetization opportunities that we had never considered. This is the team you want on your side for your next project!

Software Development Companies FAQs

What are the most requested services of custom software development firms?

The most requested services from custom software development firms are almost entirely AI-based products, delivered primarily through web application development, mobile development, AI agent development, and legacy system refactoring. UX/UI design, cloud infrastructure, DevOps, and QA automation are typically not sold as standalone services; instead, they are embedded within each of these project types.

As reported by Diffco, year-over-year trends show a prevailing shift: AI agent development has grown from a niche request into a significant share of overall volume, while demand for legacy system refactoring continues to rise as clients seek to prepare their existing systems to support AI capabilities.

ServiceShare of total demand
Web application development40%
Mobile app development30%
AI agent development20%
Legacy system refactoring10%

How much does a software development company charge for its services?

Software development services typically cost $50,000 for MVPs to $2 million+ for enterprise software. US developers generally charge $120-$200/hour, while developers in Europe and Asia charge around $25-$150/hour.

How do I determine if a global company is the right size for my project?

To determine if a global software development agency is the right size for your project, match project complexity and scale to company capacity.

Choose a large/global agency with 1000+ staff, if your project:

  • Is complex or enterprise-grade, includes multiple software solutions, integrations, and compliance
  • Requires multiple roles in parallel (project management, UX/UI design, backend, quality assurance (QA), DevOps)
  • Needs 24/7 support, multi-time-zone delivery, or long-term maintenance

Large software development companies reduce delivery risk for complex programs but typically charge higher rates and use more structured processes.

Choose a small or mid-size agency with 10-200 staff if your project:

  • Is an MVP or mid-scale build
  • Requires speed, flexibility, and direct access to senior talent
  • Has a tighter budget and well-defined scope

Who owns the Intellectual Property (IP) and source code at the end of the project?

In most software development projects, the client owns the Intellectual Property (IP) and source code upon completion of the engagement, unless the contract explicitly states otherwise. Standard practice dictates that the ownership of the source code, documentation, design elements, and custom deliverables belongs to the client upon full payment. Contracts typically use "work made for hire" or an IP assignment clause to formalize this. 

Third-party or open-source components, however, are not owned by the client. Instead, they are used under their respective licenses. Some agencies retain ownership of pre-existing frameworks or reusable tools and grant the client a license to use them. You should also know that IP ownership is not automatic. To avoid disputes, ensure the contract clearly states full IP and source-code ownership transfers to you upon payment, with no usage limitations.

What tools and frameworks do software developers use?

They use various tools and frameworks, depending on the type of digital product they’re building. But the most common include: 

  • Full-stack JavaScript: MERN, MEAN, Jamstack (ex, Next.js)
  • Backend: Java-Spring, Python, Django, Ruby on Rails, LAMP
  • UI and Cross-Platform Development: React, Angular, Vue, Qt
  • Languages: JavaScript, TypeScript, Python, Kotlin 
  • AI and Data-Driven Development: Python, Hugging Face, LangChain, Apache Spark, Kafka, Kubeflow, Lite, ONNX, Replit
  • QA and Testing: Selenium, Cypress, Jenkins, GitLab, JMeter, OWASP ZAP, Testim, Mabl

What are the best software development companies in 2026?

What questions should I ask before hiring a software development company?

Before hiring a software development company, ask:

 

  • Have you built similar software before?
  • Which technologies will you use?
  • Who will work on my project?
  • What is included in the scope?
  • How long will development take?
  • How do you handle testing and security?
  • Do you provide support after launch?

How do I reduce the risk of hiring the wrong software development company?

Check the company’s exit terms and review cadence before comparing prices. Short notice periods and frequent demos give you more opportunities to spot problems and change direction early. For example, Designli uses biweekly demos, offers a refundable first 14 days, and allows clients to cancel with 30 days’ notice.
