Most discovery calls for Java application development start with a comparison: who else did you talk to? The honest answer is usually that you have spoken to two of the firms below. We think it is worth knowing where the strengths and weaknesses sit before signing — including ours. This list reflects firms commonly evaluated head-to-head with ours in client RFPs, and firms our clients arrive at after trying others first.
What follows is a subjective evaluation of eight Java consultancies. We are not affiliated with any of them. These observations are our opinion based on industry exposure, publicly available information, and our own engagement experience — they may not reflect the current reality at each firm. The verdict at the top of each entry reflects what we would recommend for which buyer — not which firm is the most popular this quarter.
Independence statement: no firm on this page pays us, partners with us, or refers to us. The rankings and observations are editorial opinion, drawn from publicly available information and client conversations. Conditions at any firm can shift quickly; treat this as a starting point, not a final answer.
1. EPAM Systems
Enterprise Java outsourcing — broadest scale
EPAM is the consultancy our clients most often arrive having considered or rejected. Founded in 1993 and headquartered in Newtown, PA after relocating from Belarus following sanctions, EPAM employs over 53,000 engineers globally with deep Java practice areas in financial services, healthcare, and telecom. The firm's enterprise practice spans Spring Boot, Quarkus, Kafka, and JVM tuning for systems handling billions of transactions.
Where EPAM works well: very large enterprise programs (often 50+ engineers on a single account), highly-regulated industries where their compliance experience is real, multi-year staff augmentation where rate consistency matters. Their architects at the L4+ level are genuinely strong; their senior engineers have a strong industry reputation.
Better fit elsewhere for: mid-market companies often pay enterprise-tier rates without getting enterprise-tier service consistency — the L1-L2 engineer mix on a small account can be inconsistent. The procurement and SOW process is heavyweight relative to a 6-engineer team's needs. For under-100-engineer programs we more often recommend smaller specialist firms.
2. GlobalLogic
Hitachi-owned Java consultancy — enterprise + product engineering
GlobalLogic, acquired by Hitachi in 2021 for $9.6B, is a Java-strong digital engineering firm. Founded in 2000 in San Jose, GlobalLogic has roughly 30,000 engineers concentrated in India, Ukraine, and Latin America, with practice areas spanning Spring Boot enterprise applications, embedded Java, and Java-based IoT platforms.
Where GlobalLogic wins: product engineering programs where the deliverable is a long-running platform rather than a discrete project, embedded Java work (medical devices, automotive, industrial IoT), and Java-heavy IoT platforms. The Hitachi acquisition strengthened their hardware-software integration capability significantly.
Where it struggles: pure consulting engagements without long-term product engineering scope. Hourly rates have crept upward post-Hitachi acquisition; the value-per-dollar gap with smaller firms has narrowed. Like EPAM, the bench depth means engineer continuity needs contractual protection.
3. Thoughtworks
High-end Java/Kotlin consulting — XP and CD originators
Thoughtworks is the premium tier of Java consulting and the originator of many modern engineering practices. Founded in 1993 in Chicago, Thoughtworks has 11,000+ employees globally with practice areas in Java/Kotlin, microservices, continuous delivery, and the Thoughtworks Technology Radar that influences industry-wide tool adoption.
Where Thoughtworks earns the premium: greenfield architecture work for established companies entering new product areas, organizational transformation engagements where engineering practice maturity matters, and JVM-heavy fintech or healthcare platforms with high quality bars. The senior consultants are genuinely among the best in the industry.
Where the cost is not justified: cost-sensitive engagements, organizations not ready to absorb XP-style practice changes, projects where the existing team is mature enough that adding Thoughtworks engineers does not lift outcomes. Their rates run 30-50% above EPAM/GlobalLogic for comparable work.
4. Endava
UK-listed Java/digital consultancy — strong fintech practice
Endava is the largest UK-listed Java-strong digital consultancy. Founded in 2000 in London and IPO'd on NYSE in 2018, Endava has roughly 11,000 engineers concentrated in Eastern Europe and Latin America with practice areas in payments, banking, telecom, and retail systems. The firm has been a quiet leader in Java payments infrastructure work.
Where Endava is strong: payments infrastructure (genuine deep experience with Visa, Mastercard, and merchant-side payment processing), European compliance regimes, and engagement structures where you need 20-40 engineers continuously without the EPAM-scale procurement burden. Their UK presence helps with EU data residency.
Better fit elsewhere for: organizations without an existing payments or banking flavor — Endava's institutional knowledge is concentrated there. Their generalist Java engagements are specialized in their core segments. Smaller engagements (under 8 engineers) get less institutional attention than larger ones.
5. Persistent Systems
Indian Java consultancy — cost-effective at scale
Persistent Systems is one of the largest Indian Java consultancies. Founded in 1990 in Pune, India and IPO'd on NSE, Persistent has 23,000+ engineers with strong Java practice areas and a recent push into Java + AI engineering. The firm operates primarily on engagements where cost efficiency at scale matters more than premium tier delivery.
Where Persistent wins: large enterprise programs with 30+ Java engineers where blended rates need to come in under $80/hr, software product engineering where IP is yours and ongoing maintenance is contracted, and Java + ISV partnerships where Persistent has formal alliance status (IBM, Microsoft, Salesforce).
Where it struggles: cultural-fit issues for North American teams unaccustomed to time-zone-bridge engagement models, premium architecture work where the senior tier is differently composed than Thoughtworks, and short engagements (under 6 months) where the ramp-up cost dominates value delivered.
6. Capgemini
IT consulting giant — broad Java practice, deep enterprise relationships
Capgemini is the broadest IT consulting firm with a Java practice. Founded in 1967 in Grenoble, France and now employing 340,000+ globally, Capgemini operates a sprawling set of Java services from staff augmentation through full digital transformation programs. The Java practice is most consolidated under Capgemini Engineering (the former Altran), which focuses on industrial and embedded Java.
Where Capgemini works: very large multi-year transformation programs where their existing enterprise relationships matter (often 100+ engineers and $50M+ TCV), embedded Java in automotive and aerospace (post-Altran), and engagements requiring multi-discipline support beyond just engineering — change management, business analysis, and operations.
Better fit elsewhere for: pure engineering projects where the business consulting layer is unwanted overhead, mid-market engagements where Capgemini's procurement and SOW process is mismatched to scale, and projects requiring deep technical specialism in a narrow area — the breadth is the value, but it can dilute focus.
7. Globant
Latin American Java consultancy — strong digital product practice
Globant is the largest Latin American Java consultancy. Founded in 2003 in Buenos Aires, IPO'd on NYSE in 2014, and now employing 31,000+ across Argentina, Brazil, Colombia, Mexico, and beyond, Globant has built a digital product engineering practice particularly strong in media, sports, and retail.
Where Globant wins: North American clients wanting near-shore Java with overlapping time zones, organizations doing serious digital product engineering (Globant has shipped for Disney, EA Sports, LinkedIn, Google), and engagements where their AI engineering pivot since 2023 matches your needs.
Better fit elsewhere for: deeply regulated workloads where their compliance specialization is concentrated differently than Endava or EPAM, very long-running maintenance contracts where their hourly model is differently structured than Persistent, and Java engagements without a strong digital product flavor — their generalist Java work is specialized in their core segments.
8. Luxoft (DXC Technology)
DXC-owned Java consultancy — strong capital markets practice
Luxoft is the Java + capital-markets practice that DXC Technology acquired in 2019. Founded in 2000 in Switzerland, now with roughly 12,000 engineers globally and concentrated capability in capital markets, automotive software, and Java backend systems. The DXC acquisition preserved Luxoft's brand and most of its team independence.
Where Luxoft works: capital markets Java work (their pre-DXC heritage is investment banking platforms — Murex, Calypso integrations, trade lifecycle systems), automotive embedded Java post their automotive practice consolidation, and engagements where their Eastern European bench is contractually viable post-2022 (most are now in Poland, Romania, and Bulgaria).
Better fit elsewhere for: organizations needing the kind of agility that has not survived the DXC integration cleanly — procurement and SOW processes are now heavyweight. Engagements outside their core capital-markets / automotive / Java backend strengths are specialized in their core segments.
