Best Software Development Companies in New York

Six Software Development Companies With Offices in New York City

These six software development companies all list a New York City office on their own websites: STRV in Tribeca, Infinum in Midtown, Thoughtworks near Madison Square Park, MojoTech on Park Avenue South, and ustwo and Work & Co in Brooklyn. Each one designs and builds digital products for clients, and each one can meet you in person in the city.

We picked firms whose New York address we could confirm on an official company page, then compared them on what they publish about themselves: their other offices, team size, services and named clients. Directories with hundreds of names often include firms with no real office in the city, so the address check was the first filter. We also added New York wage data and the state’s sales tax rules on software, because both shape what a project here really costs.

STRV, Tribeca

STRV is a digital product development company. Its New York office is at 6 St Johns Lane in Tribeca, NY 10013, and the company also has offices in Santa Monica and San Francisco in the US and in Prague and Brno in the Czech Republic. It has been in business since 2004 and has a team of more than 200 people from more than 20 nationalities.

The client list STRV publishes includes ClassDojo, Barnes & Noble, Minted, Barry’s, Autodesk and The Athletic, and the company says its clients have raised $12 billion in funding. That mix of consumer brands and venture-backed start-ups may suit founders who want one firm to handle a product from first design to launch. Ask which office your team would work from, since STRV has staff in both the US and the Czech Republic.

Infinum, Midtown Manhattan

Infinum has its New York office at 135 W. 50th Street, NY 10022, a short walk from Rockefeller Center. The US team has 30 people, and the company has worked on digital products for US clients since 2017. Its New York page lists brand experience, AI transformation consulting, product strategy and design, mobile and web apps, AI and data, custom IoT, enterprise platforms and cybersecurity.

Infinum names Citibank, ESPN, Reuters, Business Insider and Honda among its clients. The list leans toward banks, media groups and large brands, so the firm may suit companies that need enterprise security and compliance work as well as app development. Start-ups with a small first budget may want to ask early about minimum project sizes.

Thoughtworks, Madison Avenue

Thoughtworks is the largest firm on this list by footprint. Its New York office is on the 12th floor of 99 Madison Avenue, NY 10016. The company lists 61 locations in 22 countries, made up of 42 city hubs with street addresses and 19 community hubs. In the US it has street-address offices in Chicago, New York and San Francisco, plus community hubs in Atlanta, Dallas, Denver, Los Angeles and Washington, D.C.

That scale may suit large companies running long modernisation programmes, where a project may need teams in several time zones. For a small business, the same scale can mean a more formal buying process, so plan for a longer scoping stage. The general contact address on the office page is contact-us@thoughtworks.com.

MojoTech, Park Avenue South

MojoTech has its New York office on the 12th floor of 331 Park Avenue South, NY 10010, in the Flatiron area. Its other offices are at 56 Exchange Terrace in Providence, Rhode Island, at 1495 Canyon Boulevard in Boulder, Colorado, and in Olivos, Buenos Aires, Argentina.

The contact form asks for an estimated budget, and MojoTech says it believes in “transparent and upfront pricing.” It also offers to sign a non-disclosure agreement after you reach out. Sharing a budget range in the first message gives you a faster, more realistic scope, which is useful when you are comparing several firms at once.

ustwo, Brooklyn

ustwo runs its New York studio at 20 Jay Street, Suite 530, in Brooklyn’s DUMBO area, NY 11201, with the phone number +1 646-598-8629. Its other studios are in London, Malmö and Lisbon, and it ran a Tokyo studio from 2017 to 2025.

ustwo calls its offices studios, and its New York team sits in the same Brooklyn neighbourhood as Work & Co. Companies whose main concern is how a new app or service feels to use may want to ask both firms about their design and research process before comparing prices.

Work & Co, Brooklyn

Work & Co is based at 231 Front Street, 5th Floor, Brooklyn, NY 11201, a few blocks from ustwo. Brooklyn was the company’s first-ever location, and the office now spans four floors, including a user research lab. The team grew from five founders to more than 150 people working across disciplines.

An in-house research lab matters when a project depends on testing designs with real users before launch. Ask how research sessions are booked and whether your team can watch them, since that is the main reason to pick a firm with this setup.

What a Software Developer Costs in New York

Local salaries are a useful anchor before you read any proposal, because they show what the same work would cost if you hired staff yourself. Software developers in the New York-Newark-Jersey City metro area earned a mean of $152,100 a year, or $73.12 an hour, in May 2023. The national mean for the same job was $138,110 a year, so New York pay ran about 10% higher, by our calculation. The metro area employed 119,010 software developers.

We used those numbers for a worked example. Hiring three developers in-house at the New York mean wage for a six-month build would cost about $228,150 in wages alone, before benefits, payroll taxes, equipment, recruiting time and management. An agency quote for the same six months bundles those costs, plus design, project management and testing, into one figure. Comparing a quote against the in-house wage figure shows how much of the price pays for the extra roles and the agency’s overhead.

New York Sales Tax Rules for Custom and Prewritten Software

New York treats custom and prewritten software differently, and that affects how your invoices should be written. The rules come from the state’s tax bulletin TB-ST-128.

• Custom software is not subject to sales tax when it is designed and developed to the specifications of one particular buyer.
• Prewritten software is taxable as tangible personal property, whether it is delivered on a disk, downloaded or used by remote access.
• Custom changes to prewritten software are exempt only when the charge is reasonable and separately stated on the invoice.
• Services such as installation, training, maintenance and consulting are generally exempt, but when they are sold with prewritten software the charge must be reasonable and separately stated to stay exempt.

In practice, a project that builds a custom app on top of licensed tools should show the custom development, the software licences and any support plan as separate lines. If the agency bundles everything into one price, the whole bill may be treated as taxable. Our free invoice generator shows how to lay out separate line items.

How to Vet a New York Software Development Company

We built this checklist from the details the six firms publish and from the tax rules above. Use it before you sign a statement of work.

1. Visit or verify the New York address. Every firm above lists a street address. Ask where your project team actually sits, since many firms mix New York staff with teams in other cities or countries.
2. Ask for clients like you. STRV, Infinum and others publish named clients. Ask for one reference in your industry and of a similar budget.
3. Share a budget range early. MojoTech asks for one on its contact form. A range saves weeks of back and forth.
4. Sign an NDA before sharing details. Ask for it at the first call, as MojoTech offers.
5. Agree who owns the code. The contract should transfer intellectual property to you on payment.
6. Split the invoice. Custom development, prewritten licences and support should appear on separate lines under New York’s tax rules.
7. Plan time zones. Teams in Europe or South America work different hours. Our time zone converter shows the overlap with New York.
8. Check security basics. Ask how the firm handles access to your systems, and compare its answers with our small business cybersecurity checklist.

Matching a New York Development Firm to Your Project

The six firms differ most in size, reach and what they choose to publish. We matched each one to the kind of buyer its published details point to. Treat this as a starting shortlist and test it on a first call.

A shortlist of two or three firms is enough for most projects. Send each the same short brief with your goal, timeline, budget range and the platforms you need, so the proposals can be compared line by line.

Questions to Ask on the First Call

These questions draw out the details that company websites rarely cover, and the answers make proposals much easier to compare.

• Which office will lead the project, and where will the developers sit day to day?
• Who will be our main contact, and how often will we see working software?
• How do you estimate, and what happens to the price if the scope changes?
• Which parts of the build use prewritten software or paid licences, and will those be invoiced separately?
• Who owns the code, designs and accounts at the end of the project?
• What support do you offer after launch, and how is it priced?

Write the answers down and compare them side by side after the calls. Gaps in the answers are often more telling than the hourly rate.
