The best software development firm
A software development firm can build a product from scratch, extend your in-house team, or modernize an old system. The firms below differ in size, location, specialties, and engagement model, so pick based on your project type and how much day-to-day control you want.
Thoughtworks is a global technology consultancy known for engineering quality, agile delivery, and work on large, complex systems. Its teams cover strategy, design, and engineering, which helps when a project needs more than code alone. Large firms choose Thoughtworks for modernization, platform builds, and product work that must scale.
Pricing is custom and sits at the premium end, so small startups may find it out of reach for a first product. Thoughtworks suits companies with a serious budget and a complex build, where engineering quality and long-term maintainability matter most.
- Deep engineering and design talent
- Strong agile practices
- Large enterprise track record
- Premium pricing
- May be more than a small project needs
BairesDev offers nearshore software teams from Latin America, with staff augmentation, dedicated teams, and full project delivery. US time zone overlap makes daily collaboration easier than with far-offshore teams, and its large talent pool helps when you need many engineers fast. That scale suits firms that need to grow a team quickly without local hiring delays.
Team quality can vary, so interview the actual engineers assigned to your project, not just the sales team. Clear management, code review, and communication routines matter at scale. BairesDev suits firms that need nearshore capacity and can manage a distributed team well.
- Large nearshore talent pool
- Staff augmentation and project teams
- US time zone overlap
- Quality varies by team, so vet the assigned staff
- Large engagements need clear management
ScienceSoft has built custom software since 1989, covering web, mobile, data, and enterprise systems for mid-market and large firms. Its breadth helps when a project spans several areas, such as a web app plus integrations plus reporting. Longevity also gives clients a sense of stability for multi-year work.
Large-firm processes can feel heavy for a very small project, and pricing is custom, so get a scoped proposal. ScienceSoft suits firms that want a stable, broad partner for a long-running system, not just a short sprint.
- Long track record since 1989
- Wide tech coverage
- Enterprise and mid-market experience
- Large firm processes can feel slow for tiny projects
- Pricing is custom
ELEKS combines product design with software engineering, which helps teams that need user research, interface design, and development from one partner. Its enterprise experience covers logistics, healthcare, finance, and retail, among other sectors. US and European offices help with collaboration across time zones.

- Product design and engineering together
- Strong enterprise experience
- Offices in US and Europe
- Custom pricing
- Best value on larger engagements
Netguru is a Polish software firm known for web and mobile products for startups and growing companies. Its process covers discovery, design, development, and launch, which helps founders who need a full product team. Its portfolio includes consumer apps, marketplaces, and business tools.
Pricing is custom, and popular teams may have wait times, so plan timelines early. Netguru suits founders and product teams that want a design-led partner for a web or mobile product, with a clear path from idea to launch.

Its teams cover iOS, Android, web, and backend work, which helps when a product needs several platforms at once. US and European offices support collaboration with Western clients.
As with other custom firms, pricing is quote-based and fit depends on the team assigned, so vet recent mobile work in your category. Intellectsoft suits teams that need a mobile-first partner with enterprise experience.
- Mobile app strength
- Enterprise and startup clients
- Offices in US and Europe
- Custom pricing
- Project fit depends on the assigned team
Toptal is not a traditional development firm, but a network of vetted developers, designers, and project managers available for freelance engagements. It suits firms that need a specialist fast, such as a React developer, a data engineer, or a product designer, without a long hiring process. Engagements can be short or extended as needs change.
Toptal does not manage a full product build for you in the same way a firm does, so your team still owns product direction, code review, and delivery. Rates vary by specialist and are custom. Toptal suits firms with in-house product leadership that need extra senior talent quickly.
- Vetted freelancer network
- Fast matching
- Flexible engagement length
- Not a full project firm
- Quality and fit still need your management
Andersen offers dedicated development teams that work as an extension of your firm, with engineers across many stacks and domains. Team size can grow or shrink as a project changes, which helps growing firms that cannot predict hiring needs a year ahead. Its model suits long-term product work where continuity matters.
Clients must provide clear product management, since a dedicated team still needs direction, priorities, and code review. Pricing is custom by team size and seniority. Andersen suits firms that want a stable extended team, not a one-off project handoff.
- Large dedicated team pool
- Many tech stacks
- Flexible team size
- Custom pricing
- Needs clear product management from the client
How we picked these
We compared software development firms with a public track record, a clear service model, and recent work across web, mobile, or enterprise software. We favored firms with different models, from full consultancies to staff augmentation to vetted freelancers, so readers can match the model to their needs. We did not claim hands-on engagement with these firms. Our findings rest on vendor sites, firm portfolios, and public client reviews.
What to check before you hire a software development firm
Start with your project type. A full product build needs design, engineering, and testing, while staff augmentation needs strong engineers who fit your existing process. A firm that excels at one may be weak at the other, so ask for recent work in your exact model.
Team, stack, and code ownership
Interview the actual engineers who will work on your project, and check recent work in your tech stack, not just the firm portfolio. Confirm who owns the code, documentation, and intellectual property, and how knowledge transfers to your team at the end. A clear handover plan protects you if the engagement ends.
Scope, timeline, and communication
Get a written scope with milestones, acceptance criteria, and change control, since vague scopes lead to disputes. Ask about time zone overlap, communication tools, and how often you will see working software. Weekly demos beat monthly status reports for catching problems early.
Pricing and trial engagements
Compare proposals on team seniority, hours, and what is included, not just total price. A cheaper team of juniors can cost more in rework than a smaller senior team. When possible, start with a small paid trial or discovery phase before committing to a large build.
FAQ
What is the best software development firm for a startup?
Netguru and Intellectsoft suit startups that need a full product team for web or mobile, while Toptal suits startups that need a specialist fast. The best choice depends on whether you need a full team or just extra talent.
What are the best software development firms for enterprise work?
Thoughtworks, ELEKS, and ScienceSoft suit enterprise work, with deep engineering, design, and long-term support. Enterprise projects need strong process and maintainability, so vet recent large-scale work before you choose.
How much does a software development firm cost?
Costs are almost always custom, based on team size, seniority, location, and project length. Get scoped proposals from at least two firms, and compare team composition, not just total price.
Should I choose staff augmentation or a full project team?
Choose staff augmentation when you have product leadership and process in place, and choose a full project team when you need design, engineering, and delivery from one partner. Many firms offer both, so match the model to your internal capacity.
How do I vet a software development firm?
Check recent work in your stack, interview the assigned team, ask for client references, and review code samples or demos where possible. A small paid trial or discovery phase reveals fit better than a sales presentation alone.
Who owns the code when a firm builds it?
Ownership should be stated in the contract, with code, documentation, and intellectual property transferring to you on payment. Confirm this before work starts, and ask how knowledge transfer works at handover.
