Note (September 2026): Devbridge has been part of Cognizant since December 2021, and several companies on this list are not headquartered in the USA; the entries below now say so, and unverifiable revenue predictions are marked as such.
Software development companies serving the USA range from listed product firms such as Blackbaud (Charleston, South Carolina) to custom-development agencies such as Fingent (New York) and Intersog (Chicago). As of September 2026, several firms on this list are based outside the US, and Devbridge has been part of Cognizant since December 2021.
Key Takeaways
- Devbridge is no longer independent: Cognizant completed its acquisition on December 9, 2021.
- Not all ten are US-headquartered: Radixweb and eSparkBiz list Ahmedabad, India, as their main base, and InStandart lists an address in Wimborne, England.
- Blackbaud is the only publicly traded company here: it trades on Nasdaq as BLKB and reported about $1.1 billion in GAAP revenue for 2025.
- Old revenue predictions were unverifiable: the 2022 projections for Baytech, Intersog, Devbridge and Intellectsoft have no public source and are now marked as such.
- Check before you hire: confirm a firm’s legal entity, location and references directly, because agencies change owners and focus.
Note: this list was first compiled in 2023. In September 2026 each company’s status, location and headline figures were re-checked against its own website or filings; where a claim could not be confirmed, the text now says so. Confirm current details with each company before you decide.
One of the top employment opportunities is thought to be in the software development industry. It not only assures you of rapid career advancement but also unlocks a world of opportunity.

More than 650 professionals and subject matter experts work with Radixweb, including software specialists, licensed engineers, technical architects, team leaders, QA specialists, and project managers.
Baytech Consulting
Baytech Consulting is a software engineering firm whose website, as of September 2026, lists its office in Irvine, California, not San Francisco as earlier versions of this article said. The 2002 founding date could not be confirmed, because the company’s own site gives conflicting figures. It specializes in creating unique technological solutions for companies operating in a variety of industries, including finance, healthcare, and education. Utilizing AI algorithms and cutting-edge tools like Node.js, React, and Elixir, they provide end-to-end product design, maintenance, and development services to guarantee the high speed and scalability of the apps they create.
Earlier versions of this article said Baytech expected to handle over $150 million by 2022; no public source for that figure was found, so treat it as unverified. Baytech’s site cites 120+ projects for clients from small businesses to Fortune 500 companies. Custom software product planning, mobile apps, web services and web applications, and other IT infrastructure consulting services are just a few of their amazing talents.
Instandart
InStandart (as its website styles the name) now describes itself as a CAD engineering company that builds CAD and BIM automation tools, such as AutoCAD, Revit and AVEVA E3D plugins, for construction, formwork, EPC and oil-and-gas engineering teams.

Intersog’s strengths include the creation of mobile, cloud, and web applications as well as data analysis and insight services. It also offers knowledge and assistance with everything from strategic planning to execution. Earlier versions of this article predicted annual income above $25 million by 2022; Intersog is privately held and that figure could not be verified from a public source.
Devbridge
Devbridge is no longer an independent company: Cognizant completed its acquisition of Devbridge, a Chicago-headquartered software consultancy, on December 9, 2021, adding more than 600 engineers, designers and product managers in Lithuania, Poland, the United States, the United Kingdom and Canada. The 2009 founding date given here earlier could not be re-confirmed. Before the acquisition, Devbridge was headquartered in Chicago, Illinois; the $40 million revenue projection cited here earlier could not be verified, and Devbridge’s results are not reported separately from Cognizant’s. Devbridge provided a wide range of services, including software engineering, design, system integration, digital transformation, and more; those capabilities are now part of Cognizant. For clients from abroad, they also have offices spread out over a number of cities, such as London, Lithuania, and Poland.

The company’s staff of seasoned engineers has won numerous awards for their work and possesses proficiency with a number of different technologies, including Ruby on Rails, React Native, Python, and Node.js. Buyers looking for the former Devbridge team today should contact Cognizant, since Devbridge is part of Cognizant rather than a stand-alone firm.
Intellectsoft
A leading global provider of technology, Intellectsoft gives companies in several sectors specialized software engineering solutions. Intellectsoft says it has been operating since 2007. As of September 2026, its website lists a New York City office address (500 Fashion Avenue), while the site’s structured data still lists an address in Palo Alto, California. It offers consumers all over the world digitizing services such as app development, software engineering, IT services, platform evolution, and blockchain solutions.
Earlier versions of this article cited an analyst prediction of more than $40 million in yearly revenue by 2022; Intellectsoft is privately held and that figure could not be verified. The company’s extensive capabilities are its primary competitive advantage. It has a wealth of experience working on projects across a range of sectors, including healthcare, finance, insurance, and retail, as well as specialized knowledge based on cloud platforms like Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
Outliant
Outliant is a web design, development and digital growth marketing company.

As organizations become more technologically advanced, they help them make the most of digital technologies.

Software Development Companies in the USA: Status Check
The table summarizes what each company’s own website, filings or press releases said when checked in September 2026. “Based in” means the main location the company lists, not necessarily its legal registration.

What Does a Software Development Company Do?
A software development company designs, builds, tests and maintains software, either for clients or for its own customers. Firms on lists like this one fall into two broad types, and the difference matters when you compare them.
- Product companies sell their own software to many customers. Blackbaud is an example: it sells cloud fundraising, donor-management and financial software to nonprofits, schools and foundations.
- Service companies (agencies, consultancies and outsourcing firms) build custom software to a client’s specification. Fingent, Radixweb, eSparkBiz, Intersog and Intellectsoft work this way.
For a fuller definition of the development process and its stages, see what software development is and how the process works. AI tools are also changing how these firms work; the site’s guide to the impact of artificial intelligence on software development covers that shift.
Onshore, Nearshore or Offshore: Which Model Fits?
Where a development firm’s engineers sit affects cost, time-zone overlap and legal recourse. Several companies on this list sell to US clients while listing their main base outside the US.
| Model | What it means | Typical trade-off |
|---|---|---|
| Onshore | The team works in the same country as the client | Easiest communication and contracts; usually the highest rates |
| Nearshore | The team works in a nearby country with similar time zones | Good working-hours overlap; rates vary by country |
| Offshore | The team works in a distant country, often many hours ahead or behind | Often lower rates; needs clear specifications and handover routines |
A US address on a company website does not tell you where the engineers work, so ask each firm directly. The site’s overview of the best countries for offshore software development compares the main offshore locations.
How to Choose a Software Development Company
Choosing a software development company comes down to checking facts rather than trusting rankings. These steps apply to any firm on this or any other list.
- Confirm the legal entity and location. Check which company will sign the contract and in which country, since that decides which courts and laws apply.
- Check ownership. Search for recent acquisitions; Devbridge, for example, has been part of Cognizant since 2021.
- Ask for relevant case studies and references. Speak to at least two past clients with projects similar in size and industry to yours.
- Agree who owns the code. The contract should state that intellectual property transfers to you on payment.
- Start small. A paid discovery phase or small pilot shows how the team communicates before you commit a large budget.
- Plan for maintenance. Agree on support terms, response times and handover documentation before launch.

Why Company Rankings Go Out of Date
Rankings of software development companies age quickly because the market consolidates and agencies reinvent themselves. When this list was re-checked in September 2026, one firm had already been part of a larger group since 2021 (Devbridge, acquired by Cognizant), one had moved its focus to CAD engineering automation (InStandart), and one now presents itself mainly as a web design and growth marketing company (Outliant). Revenue predictions in the original version of this list were never backed by published figures, which is why they are now marked as unverified.

Fingent (New York), Blackbaud (Charleston, South Carolina), Baytech Consulting (Irvine, California), Intersog (Chicago) and Intellectsoft (New York City) list US locations as their main base, as of September 2026. Radixweb and eSparkBiz are based in Ahmedabad, India, with US offices or addresses, InStandart lists an address in England, and Outliant is fully remote.
Is Devbridge still an independent company?
No. Cognizant completed its acquisition of Devbridge, a Chicago-headquartered software consultancy, on December 9, 2021, according to Cognizant’s announcement. Devbridge’s engineers, designers and product managers became part of Cognizant.
Is Blackbaud a software development company?
Blackbaud is a software company that builds and sells its own cloud software for nonprofits, foundations, schools and other organizations, rather than a custom-development agency. It was founded in 1981, is headquartered in Charleston, South Carolina, and trades on Nasdaq as BLKB.
How much revenue does Blackbaud make?
Blackbaud reported GAAP total revenue of about $1.1 billion for full-year 2025, according to its results release of February 10, 2026. Its 2026 guidance was GAAP revenue of $1.173 billion to $1.179 billion.
How do I check whether a software development company is legitimate?
Check the legal entity named on the contract, its registered address and ownership, and ask for references from past clients with similar projects. Compare the company’s own website with independent sources, and be wary of any revenue or ranking claim that has no published source.
