Leobit has expert competency in the full range of application development services, ranging from UX consulting and discovery to prototyping and testing. As a Microsoft Gold Certified Partner, its technology stack includes ASP.NET MVC, ASP.NET Web API, and ASP.NET Core.
Leobit staffs over 170 software engineers, architects, QA testers, and project managers from the best technical universities. The #1 .NET development company in Ukraine has worked with Fortune 500 and Silicon Valley startups.
A Norwegian SportsTech company wanted to create a cycling software platform featuring virtual routes, competitions, and challenges and enabling instructors to schedule indoor cycling classes. Using .NET 6 technology, Leobit developed a cycling solution with gamified elements and migrated it to the cloud.
The application had 60k+ downloads on Apple Store and Google Play, and the number of users grew 15 times from 20,000 to 350,000. The solution was so successful, it was acquired by a leading US-based indoor cycling hardware manufacturer.
Notable clients: Pixel Guru, Focis, Nudge, Meta Bytes
CSHARK offers end-to-end development, product design, minimum viable product (MVP) development, and supporting services. The company stays on top of the latest .NET technologies, as well as Azure, SaaS, serverless, cloud, and AWS services. From 2019 to 2021, it was named among the 1,000 fastest-growing companies in Europe.
Kanri wanted to build a digital administration system for machine operators, foremen, mechanics, and shift supervisors. The solution required data acquisition, processing, and visualization tools that could be hosted on-premises or in the cloud.
CSHARK conducted deep industry research to deliver a detailed backlog and wireframes. These integrated and automated lean processes through .NET, React.js, and TypeScript. The final product landed three new clients for Kanri, with more companies testing the solution in their factories.
Notable clients: Fox Sports, Toyota, Southwest Airlines, Nike
A Microsoft Gold Partner and top-ranked ASP.NET development company, Brainvire is an expert in web and software development solutions. Its expertise is quality management, backed up by certifications including ITIL, Prince2, and OWASP.
One of Brainvire’s clients created AI-based software to help landlords list commercial and private spaces to find tenants without needing an agency. The original solution had a long and complicated real estate publishing process, unclear property descriptions, and lacked quick data access.
Using .NET technology to convert voice queries into text, Brainvire sped up the property publishing and searching processes. With new features like geolocation, images, videos, and chat, landlords could even find tenants faster and communicate with them directly.
Notable clients: National Geographic, Paradox Interactive, Beam, Omnicar
Brainhub is a .NET development company that delivers web, mobile, and desktop projects in fintech, education, healthcare, and other industries. The company is known for its rigorous, multi-phase screening process — only the top 1.36% of applicants (a mere handful out of hundreds) pass all the phases and get hired.
Beam reached out to Brainhub to get its help in becoming a leader in the scooter-sharing market in Asia-Pacific. Its app had to support 10,000 riders daily and required an API integration for real-time data sharing with local governments.
Brainhub built a .NET-based solution consisting of the API and mobile and desktop app, incorporating new features like smart charging monitoring. The app was installed over 10 million times, positioning Beam as the largest micromobility name in APAC.
Altoros is a .NET development provider of high-end solutions for IoT, finance, automotive, marketing, construction, and many other industries. Awarded the 2022 TechBehemoths Award for Top Custom Software Development Company in the United States, its 350+ employees, of which 56% are seniors and 44% are mediors, are hired from the top 3% of development talents in Europe and the US.
An anti-doping provider for sports organizations needed help migrating its iPad management system app to the .NET framework. Built on legacy technology 10 years ago, the app stopped functioning after the release of a new iOS version. The system also struggled to adapt to changing workflows for each new sporting event, requiring extra time and developer interventions.
Altoros successfully migrated the app to a new technology stack, eliminated maintenance issues, and automated doping control workflows. It also moved 2.5 billion documents, enabling non-technical staff to create custom processes and saving the client thousands of dollars.
ScienceSoft is a .NET development expert in the design, implementation, testing, evolution, integration, and modernization of applications. The company has been a Microsoft Partner since 2008 and counts over 220 large-scale .NET projects in its portfolio.
One of ScienceSoft’s clients had outdated software for monitoring and forecasting energy consumption. The company seamlessly transitioned the desktop application, which was written in the obsolete Microsoft VB6.0 language on MS SQL Server, to the .NET technology stack.
This improved the performance and integrated better reporting features, such as chart and presentation creation.
Notable clients: Redline, Health Workforce NY, IRIS, Flimp Communications

It provides developers from the top 5% of talent, with free support from a project manager, quality auditor, and technology experts.
Mortgage provider Protec wanted a software solution to simplify document preparation, processing, and compliance in its loan processes. Many procedures were done manually, taking weeks to complete.
Clarion developed an easily upgradeable cloud-hosted web application that can store a large amount of loan data. The app reduced invoice generation time from weeks to a couple of days, and the new automation system for database scaling saves Protec approximately $2,000 per month.
Notable clients: Anglo American, Bemi OY, AE Partners

A .NET development company is a business that specializes in creating software applications, dynamic websites, games, and other services based on .NET, Microsoft’s free, cross-platform, and open-source development platform. Today, over 38 million live websites use ASP.NET.
.NET development companies typically have expertise in the new, unified .NET Standard and the following components:
.NET Framework: Collection of tools, programming languages, and libraries for creating software and applications.
.NET Core: Open-source developer platform for building applications
Xamarin: Platform for building applications for iOS, Android, and Windows
What is a full-stack .NET developer?
A full-stack .NET developer builds both the frontend/interface and the backend/content management systems (CMS) of .NET projects. Their wide range of skills in both technology stacks presents some key advantages over a front-end- or back-end-only developer:
You’ll need fewer team members to complete a project, significantly reducing overall costs.
Familiar with both sides of the project, a full-stack developer can troubleshoot, fix issues, and fill gaps quicker.
As there’s no back and forth between front- and back-end developers, there’s less miscommunication, mistakes, and delays.
Are .NET and ASP.NET the same?
No, .NET and ASP.NET are two different things – the former is a software framework, and the latter is an application.
.NET is a framework used to build various software applications and services, including applications like ASP.NET.
ASP.NET is a software application used to build websites, web services, and web applications.
You can think of ASP.NET as an application developed on the .NET framework for the specific purpose of creating software for the web.
What services does a .NET development company provide?
A .NET development company typically provides a range of software development services, including:
Desktop application development
Web application development
Mobile application development
Game development
Cloud solution development
Technical support and maintenance
Over the course of a project, a .NET developer may:
Plan the software development process and break it down into tasks
Write source code using C#, F#, or Visual Basic
Test the software using manual and/or automated techniques
Discuss project progress with the stakeholders and present developed functionalities
Launch the software and make sure everything operates as planned
Maintain and update the software after deployment
How much do .NET development companies charge for their services?
.NET development companies charge $5,000 to $20,000 for simple projects and up to $250,000 for large-scope projects, like a customer relationship management (CRM) system for a medium-sized business. Extremely large and complex projects that take years to develop may even require a budget of over $1,000,000.
Here are some typical price ranges for different kinds of .NET projects:
Small website: $10,000 to $50,000+
Cross-platform mobile app: $50,000 to $150,000+
Large enterprise application with integrations: $200,000 to $1,000,000+
The top 50 .NET development companies on DesignRush charge an average of $57/hour. Roughly 13% of the .NET development companies on DesignRush accept projects with a minimum budget of less than $1,000, while 5% have a $50,000+ minimum budget.
Why should you hire .NET developer companies?
You should hire a .NET developer because outsourcing offers the following benefits:
You save costs: According to an in-house vs. outsourcing report, outsourcing software development costs $45/hour on average, compared to $75/hour for in-house development.
They have more experience: Experienced developers with a lot of .NET projects under their belt typically deliver higher quality work.
Faster process: With an external team, you don't need to expend resources to recruit and train an internal .NET developer.
Here is an example of a successful project by a .NET company called ScienceSoft: a client needed an efficient BI solution for internal management, external financial analytics, and automated customer invoicing. The .NET company developed an analytics web portal, client web portal, reporting tools, and other supporting features from scratch.
After the .NET development company implemented the BI solution, it improved the speed of reporting by 90%. It also fully automated processes like customer invoicing, enabling significant time savings.
How do you choose the best .NET development company for your business?
You can choose the right .NET development company by following these steps:
Define project scope: Decide on a minimum viable product (MVP), product features, and functionality.
Set project requirements: Make a checklist of goals and the means to achieve them (e.g., deliverables list, timeline, communication guidelines, preferred technologies, etc.).
Set a budget: Look for the best talent in a range you can afford. If you have a small budget, try expanding your search to countries with more affordable prices.
Inquire about experience: Ask the .NET development company for a portfolio and similar project examples from your industry.
Check credentials: Ask for .NET certifications like Microsoft Certified Solutions Associate (MCSA), Microsoft Certified Solutions Developer (MCSD), or Microsoft Training Associate (MTA).
Choose the development approach: Depending on the project, the company should offer an Agile, Waterfall, or hybrid development methodology.
Send a request for proposal (RFP): An RFP contains the project introduction and scope, technical requirements, evaluation criteria, budget, and submission guidelines. Select up to five .NET development companies and send them an RFP.
Review RFPs: Go through each proposal, compare results, and interview your shortlisted companies.
Make a decision: Pick a .NET company based on your top criteria and examine the contract before signing.
