How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- This article covers services companies you hire to build software, not software products, so pricing is quote-based and engagement model matters more than a price page.
- EPAM and Cognizant lead for large enterprise programs, with tens of thousands of engineers and deep industry coverage across the United States.
- Thoughtworks leads for engineering-led modernization, where how your team builds matters as much as what gets built.
- Nearshore firms like BairesDev suit US teams that want time-zone overlap at mid-range rates, while onshore boutiques suit teams that need senior-only US staff.

EPAM Systems, headquartered in Newtown, Pennsylvania, reported $5.457 billion in 2025 revenue with about 62,850 people, making it one of the largest product engineering firms serving US clients. Its strength is large product and platform engineering programs across regions and technical disciplines, with a client base weighted toward Forbes Global 2000 companies and ambitious startups.
The scale cuts both ways. EPAM engagement budgets suit enterprises, not startups with tens of thousands of dollars, and its delivery model spans many countries, so confirm how much of your team sits in US time zones. For a large platform build with several workstreams, EPAM is the most proven engineering partner on this list.
What we like- About 62,850 staff and deep engineering bench
- Strong product and platform record
- US headquarters in Pennsylvania
Watch out for- Enterprise minimum budgets are large
- Less suited to small fixed-scope projects

Thoughtworks, founded in Chicago, is known for engineering-led delivery where the partner improves how your internal teams build software, not just what they ship. Its consultants bring agile practices, test automation, and architecture discipline into organizations modernizing legacy systems, which is why it scores highly for modernization programs.
Rates sit at the upper-mid range, and its bench is smaller than the global IT services firms, so very large multi-team programs may need a second partner. If your challenge is as much delivery practice as product scope, Thoughtworks is the strongest fit here, and its Technology Radar publications show its engineering thinking in public.
What we like- High engineering rigor
- Agile delivery practice
- Strong modernization record
Watch out for- Consultancy rates sit at the upper end
- Smaller delivery bench than EPAM or Cognizant

Globant reported $2,454.9 million in 2025 revenue with 28,773 people, and 944 customers spent over $100,000 in 2025, with 336 spending over $1 million. Its studio model organizes teams around digital experience, product engineering, and AI, and its AI Pods model reported $32.8 million in annual recurring revenue in early 2026.
Delivery leans on Latin America nearshore teams plus global studios, which gives US time-zone overlap without US onshore rates. Globant suits large brands building customer-facing digital products, while smaller companies may find its minimums high. For experience-heavy programs at global scale, Globant belongs on the shortlist.
What we like- AI Pods delivery model
- Strong experience design
- Large brand client base
Watch out for- Luxembourg headquarters with LATAM-heavy delivery
- Enterprise-scale minimums

Cognizant, headquartered in Teaneck, New Jersey, reported $21,108 million in full-year 2025 revenue with about 351,600 people, making it one of the largest enterprise IT services firms serving US clients. Its breadth covers banking, healthcare, retail, and manufacturing, with managed delivery across many teams under one contract.
Delivery is offshore-heavy, so US clients should confirm team composition, overlap hours, and escalation paths in the statement of work. Large programs also need strong client-side governance, since a vendor this size will not self-direct your roadmap. For enterprises consolidating many applications under one partner, Cognizant offers unmatched capacity.
What we like- About 351,600 staff
- Broad industry coverage
- US headquarters in New Jersey
Watch out for- Offshore-heavy delivery mix
- Large programs need strong client governance

Accenture is the largest firm on this list, with fiscal 2026 revenue of $74.18 billion and about 814,000 people, serving roughly three quarters of the Fortune Global 100. Its advantage is scale: multi-year transformation programs, global rollouts, and complex organizational change paired with technology delivery, all under one partner.
That scale brings overhead, and Accenture is not built for small fixed-scope builds. Clients should also expect a consulting-led engagement with structured governance rather than a lean product team. When the program spans platforms, operations, and organizational change at global scale, Accenture is the default comparison point.
What we like- About 814,000 people and $74 billion revenue
- Broad industry and technology coverage
- Global delivery
Watch out for- Largest-firm overhead and rates
- Small projects are not its focus

BairesDev provides nearshore engineering teams from Latin America working in US time zones, which suits US product teams that want daily overlap without onshore rates. Its model is team extension and dedicated teams rather than fixed-scope delivery, so clients keep product direction while BairesDev supplies engineers.
The model demands client-side product leadership, since BairesDev engineers execute your roadmap rather than defining it. Quality also varies by pod, so interview the actual engineers assigned, not just the sales team. For US teams that need to scale engineering capacity quickly in their own time zone, BairesDev is a practical mid-range option.
What we like- Latin America teams in US time zones
- Mid-range rates
- Fast team assembly
Watch out for- Staff augmentation model needs client-side product leadership
- Quality varies by pod

ScienceSoft suits mid-size companies that want a fixed-scope custom software project with a defined budget and timeline. Its IT consulting and development practice covers enterprise software, ERP, and CRM projects, and its pricing sits in the mid range rather than the upper-mid enterprise band.
Its US brand presence is smaller than EPAM or Cognizant, so reference checks matter more, and delivery is partly offshore, so confirm overlap hours. For a mid-market company with a clear scope and a fixed budget, ScienceSoft offers a credible alternative to the global giants.
What we like- Fixed-scope project experience
- Mid-market pricing
- Broad technology coverage
Watch out for- Smaller brand presence in the US
- Delivery partly offshore

10Pearls is a product development agency focused on US mid-market companies, combining design and engineering for web, mobile, and AI products. Its model suits companies that need a full product team rather than staff augmentation, with strategy, design, and delivery under one roof.
Scale is the limit. 10Pearls cannot match EPAM or Cognizant for multi-team enterprise programs, and its rates sit in the mid range. For a mid-market company building or rebuilding a product with a partner that owns delivery end to end, 10Pearls is a strong fit.
What we like- Product development focus
- US mid-market experience
- Design plus engineering
Watch out for- Smaller scale than global firms
- Less suited to multi-year transformation
How we chose
We compared 2026 ranking guides and company disclosures for each firm, checking headquarters, headcount, revenue, delivery model, and US client focus. We favored firms with a clear US footprint and a distinct engagement model, and we treated revenue and headcount figures as company-reported guides, not quality scores. We did not claim hands-on testing, and every scale figure here traces to a published company report or ranking guide. Rankings shift as firms report new results, so recheck headcount and revenue before relying on them for a hiring decision.
Choosing the right engagement model
Pick the model before the vendor. Team extension suits companies with product leadership in place that need extra engineers fast, while a dedicated team suits a defined product area owned jointly. Fixed-scope projects suit clear requirements and fixed budgets, but they punish changing scope, so only choose fixed price when requirements are genuinely stable.
Vetting a services partner
Ask for case studies in your industry and speak with past clients, not just the references the vendor selects. Interview the engineers who will actually work on your project, confirm time-zone overlap and escalation paths, and insist on written terms for intellectual property, confidentiality, and data security. A short paid discovery phase often reveals more than a long sales process. During discovery, watch how the vendor handles disagreement, how quickly it produces working software, and whether its estimates stay stable once real requirements surface, since those behaviors predict the full engagement better than any pitch deck.
Budget reality
None of the firms here publish prices, and none describes a client with a budget in the tens of thousands, so budget accordingly. Mid-range nearshore teams typically start around $50 to $99 per hour per engineer in published guides, while enterprise firms price higher and onshore boutiques higher still. Get a written estimate tied to team composition, not just a blended rate, before committing. Also confirm whether project management, QA, and DevOps sit inside the quoted rate or bill separately, since those roles can add 20 to 30 percent to a team quote, and ask how rate changes work at renewal so a year-two increase does not surprise you.
Frequently asked questions
How much does hiring a software development company cost?
It depends on model and location. Published guides list nearshore engineers from $50 to $99 per hour, while US onshore and enterprise firms price higher. Fixed-scope projects are quoted per project, and large enterprise programs run into six or seven figures annually. Discovery phases, typically one to three weeks, are often billed separately and are worth paying for before a large commitment.
Should I choose a large firm or a boutique agency?
Large firms suit multi-team enterprise programs and global rollouts, while boutiques suit single-product builds with senior staff. Mid-market companies often get better attention and flexibility from a mid-size agency than from a global firm where they are a small account.
Is nearshore or offshore delivery safe for US companies?
Yes, with the right controls. Confirm time-zone overlap, interview assigned engineers, require written IP and confidentiality terms, and set up weekly delivery reviews. Nearshore Latin America teams offer US-hour overlap, while offshore teams need async practices to match.
What should be in the contract with a development company?
Cover scope, team composition, IP ownership, confidentiality, data security, acceptance criteria, change control, and exit terms including code handover. Insist on a named project lead, reporting cadence, and a clear path for replacing underperforming team members.
How long does a typical custom software project take?
Small products can ship in 8 to 12 weeks, mid-size platforms typically take 4 to 9 months, and enterprise transformations run a year or more. Discovery, design, and testing time are often underestimated, so ask vendors to break estimates down by phase.
