This comparison names the ones that do, judges them on criteria you can verify, including whether they will tell you when one agent is enough, and links every fact to its source. November 8, 2026 1 minute Share: We searched for the best multi-agent system development companies on 5 November 2026 and read every ranked list on the first page. Each one put its author first: Master of Code, Omdena, Boldare, EffectiveSoft, DevCom and GoGloby. Two more, on general news sites, carry no byline and no sponsor label and link only to the firm they rank first. Two are already dated 2027. None links evidence for any firm except its own. This comparison follows [the method we use for all of our comparisons](https://vindler.solutions/blog/how-we-compare-ai-firms): real firms, criteria you can verify from the outside, a source behind every fact, no scoring, and our own entry written to the same standard and placed last. It covers firms that build systems in which several agents divide the work between them. Firms whose only agent work is a single agent are left out of the profiles, however good that work is. ## The question most lists skip Most systems sold as multi-agent should be one agent. Every extra agent adds a handoff, and every handoff adds latency, tokens, and a new place for the request to be misrouted. A system with a supervisor and five specialists can be the right design when the domains are separate, the tools differ, and each part can be tested on its own. When most requests touch one domain, a single agent with good tools is cheaper, faster and easier to debug. We made the same argument in [an earlier piece](https://vindler.solutions/blog/multi-agent-systems-hype-vs-reality), after converting a client's multi-agent support system into one agent with structured state. So the first thing to check about a multi-agent firm is whether it has ever said in public that you do not need one. A firm that only ever recommends more agents has not told you much about its judgement. ## Six criteria you can check from the outside 1. **Published writing on when one agent is enough.** The firm has said, with a reason, when it would not split a system, or when it consolidated agents after building too many. 2. **Named multi-agent work with the architecture stated.** A named client, the number of agents and their roles, the orchestration pattern (supervisor, handoff, graph), and the tools the agents can call. "A multi-agent system for a leading bank" does not pass. 3. **Agent-level evaluation described.** Routing accuracy, evaluation sets per agent, checks on the sequence of tool calls, regression runs on every change, and human review feeding the test set, with the tools named. 4. **Traces and cost per run in public.** Evidence that the firm traces each agent step and reports latency, token use or cost per task. These numbers decide whether a multi-agent design survives its first invoice. 5. **Code in the frameworks themselves.** Open-source packages or contributions in the framework the firm builds on, in a repository anyone can open. Partner badges count for less than code. 6. **Who owns the orchestration layer.** Whether the agents run on an open framework in your cloud, or on the firm's own platform. A proprietary orchestration platform is the multi-agent version of lock-in. ## The firms Every fact below was collected on 5 November 2026 from the firm's own site, its Clutch profile where one exists, AWS and framework vendors' blogs, GitHub, and press. Firms are grouped by the kind of buyer they fit, not ranked. ### Framework specialists These are the firms whose public work shows the most about how their agents are built, tested and paid for. **Focused** (Chicago, with offices in Denver and London, founded 2018) is a LangChain partner since 2024 and writes the clearest public rules on when not to build a multi-agent system ([partnership announcement](https://www.newswire.com/news/focused-labs-announces-strategic-partnership-with-langchain-to-foster-22232271), [Clutch](https://clutch.co/profile/focused)). Its [supervisor versus swarm write-up](https://focused.io/lab/multi-agent-orchestration-in-langgraph-supervisor-vs-swarm-tradeoffs-and-architecture) says to skip multiple agents with fewer than three distinct domains, when most requests touch one domain, or without evaluations per agent, and it compares the two patterns on latency, LLM calls, tokens and routing accuracy (94% against 91%, on a single scenario with no sample size given). It recommends writing the routing evaluation before writing the second agent. Its named work: two agents taken to production at [Coinbase](https://focused.io/case-studies/bringing-agents-into-production-at-coinbase) in about six weeks with LangSmith evaluation pipelines, and a human-in-the-loop claims system for [One Claim Solution](https://focused.io/case-studies/building-ocss-multi-modal-human-in-the-loop-claims-agent) built as purpose-specific LangGraph subgraphs, with about 90% document extraction accuracy. Neither case is a set of peer agents, which fits its own advice. Headcount sources disagree (Clutch shows 10 to 49, the firm says 60 engineers). Clutch lists a $100,000 minimum at $200 to $300 per hour and no reviews. Best for an enterprise committed to LangGraph and LangSmith that wants the patterns taught to its own team. Look elsewhere below $100,000. **Vstorm** (Wrocław, founded 2017, 10 to 49 people) publishes the most per-system numbers of any firm here ([Clutch](https://clutch.co/profile/vstorm-leading-ai-agent-company)). For the UK printer [Mixam](https://vstorm.co/case-study/ai-agent-for-order-recommendation-and-completion/) it built a three-agent advisor with fifteen tools, including one that only produces valid combinations of cover, pages and binding, and it reports more than 10,000 users a day, conversion to sale rising from about 20% to about 40%, and token costs of about $2,000 a month. For the fintech [Yeeld](https://vstorm.co/case-study/multi-agent-financial-coach-and-assistant/) it built a supervisor with six specialists on LangGraph, though that case gives no metrics. A [text-to-SQL case](https://vstorm.co/case-study/from-single-agent-to-hybrid-agent-graph-architecture-our-journey-with-pydantic-ai-and-text-to-sql/) explains why it moved SQL generation out of an agent and into a fixed eight-step graph: when a wrong join is costly, a deterministic path is safer than a free agent. Its code is public. The Pydantic AI team endorses its packages, and Pydantic counts more than 30 Vstorm systems in production on its framework ([Pydantic](https://pydantic.dev/articles/harness-week), [GitHub](https://github.com/vstorm-co)). Clutch shows 4.9 across 22 reviews, a $10,000 minimum and $100 to $149 per hour. Best for a product team that wants a mid-market rate and a firm that shows its numbers. Ask about IP terms, which are not published. **deepsense.ai** (Warsaw, with an office in Palo Alto, founded 2014, 50 to 249 people) has a client-reviewed multi-agent system on its Clutch profile: six agents for Cato Networks' customer support, orchestrated with LangGraph on Claude 3 models in AWS Bedrock. A planner agent directs atomic agents for network analysis, event analysis and configuration, and a responder agent writes the reply from the full conversation history. The reviewer reports over 80% user satisfaction with the responder and 20% less time spent per ticket ([Clutch](https://clutch.co/profile/deepsenseai)). It maintains [Ragbits](https://github.com/deepsense-ai/ragbits), an open-source framework that supports agents, MCP servers and agent-to-agent communication. We could not find a live copy of its widely shared post on a fifteen-agent MCP system, so it is not cited here. Clutch shows 5.0 across 11 reviews, a $25,000 minimum and $100 to $149 per hour. Best for a planner and worker build on AWS Bedrock with a European team and verified references. ### Cloud partners **Caylent** (Irvine, California, founded 2015, 250 to 999 people, AWS Premier partner with the Agentic AI Specialization) wrote the most candid post here on getting multi-agent design wrong and fixing it ([Clutch](https://clutch.co/profile/caylent), [specialization](https://caylent.com/blog/caylent-achieves-the-aws-agentic-ai-specialization)). Written with its client CloudZero, [Evolving multi-agentic systems](https://caylent.com/blog/evolving-multi-agentic-systems) describes flows of five to ten hops taking tens of seconds, the consolidation of "a fleet of specialized agents" into fewer, more capable ones, and the line "The industry has overhyped agent swarms". The resulting CloudZero Advisor runs five specialised agents on Bedrock AgentCore, with two to four seconds to first token per step and DeepEval for validation ([AWS](https://aws.amazon.com/blogs/apn/aws-partners-demonstrate-enterprise-ai-agent-solutions-with-amazon-bedrock-agentcore)); the two sources give different figures for latency before the change, 30 seconds in one and 6 to 10 in the other. No prices are published and Clutch shows no reviews. Best for a company standardised on AWS that wants AgentCore and Strands built by people who have already consolidated an over-split system. Look elsewhere if you are not on AWS. ### Large integrators **Grid Dynamics** (San Ramon, California, founded 2006, 4,838 people at June 2026, listed on Nasdaq) reports two multi-agent programmes in production, a commerce system for a global food and beverage company and a transformation for a global payments company, neither named and neither described in technical detail ([MACH Alliance award release](https://finviz.com/news/383844/grid-dynamics-earns-mach-alliances-2026-agent-ready-award-for-production-scale-agentic-ai), [Q2 2026 results](https://finviz.com/news/375299/grid-dynamics-reports-second-quarter-2026-financial-results)). Its most useful public writing is about one research agent for a Fortune 500 manufacturer: its first version kept LangGraph state in Redis and fed requests to executors through Kafka, and it suffered state expiry, race conditions and agents that silently stalled, and the team moved each graph node to a Temporal activity and removed thousands of lines of retry code ([Temporal](https://temporal.io/blog/prototype-to-prod-ready-agentic-ai-grid-dynamics)). Delivery runs on its own GAIN platforms, which is the ownership question to ask. Best for an enterprise that wants embedded engineers at scale and cares about durable execution. Ask for a named multi-agent reference. **Cognizant** (Teaneck, New Jersey, about 360,000 people, Claude Partner Network Global Premier tier) is the only integrator here with its own open-source multi-agent framework ([Claude partner directory](https://partnerhub.claude.com/directory)). [neuro-san](https://github.com/cognizant-ai-lab/neuro-san) defines agent networks in configuration files and is Apache 2.0 licensed, though in May 2025 production use required Cognizant's commercial services suite ([May 2025 release](https://kyodonewsprwire.jp/release/202505229311), [April 2026](https://www.cognizant.com/us/en/ai-lab/blog/neuro-ai-multi-agent-accelerator-global-ai-award)). Its named client is Telstra, announced as working with Cognizant "to test and deploy" multi-agent systems, and we could not confirm a production system. Its largest deployment is internal: an intranet for more than 350,000 employees, with support tickets down 30% after five months by its own account, and an evaluation framework that replays workflows to measure run-to-run consistency. No prices are published. Best for a large enterprise that wants an integrator with its own framework and the bench to staff it. **Genpact** (New York, about 146,500 people) built a supervisor that routes questions to specialist agents for accounts, entities, items and transactions for [Apex Fintech Solutions](https://aws.amazon.com/blogs/apn/aws-partners-demonstrate-enterprise-ai-agent-solutions-with-amazon-bedrock-agentcore), so investigators can query daily trades across millions of brokerage accounts in plain language, on Bedrock AgentCore. The system runs on riskCanvas, Genpact's own financial crime product, so the agents sit on a vendor platform. No accuracy, cost or price figures are published. Best for a financial crime team already on riskCanvas. It is a narrow fit beyond that. ### European engineering consultancies **Eficode** (Helsinki, founded 2005, 250 to 999 people) has the only Microsoft Agent Framework example we found: a two-agent system in Microsoft Teams for more than 14,000 students at [University West](https://eficode.com/client-stories/how-university-west-built-a-production-ready-ai-agent-system) in Sweden, with a course agent over course materials and a schedule agent connected to the timetable, on Azure AI Foundry. The university's own two part-time AI developers built it with Eficode on architecture and governance, so the client owns and runs it. The case has no metrics. Clutch shows a $10,000 minimum, $100 to $149 per hour and no reviews ([Clutch](https://clutch.co/profile/eficode)). Best for a Microsoft organisation in Europe that wants to build in-house with help. ### Where Vindler fits We are a small founder-led firm headquartered in São Paulo, working with clients in the United States and Europe, with one to ten senior engineers on an engagement and the founder writing code on every one. Our main multi-agent system in production is the conversational assistant for Typeform, where we worked with their AI engineering team: a supervisor that routes each request to six specialised agents for forms, smart forms, contacts, automations, pages and connectors over the agent-to-agent protocol, on LangGraph and AWS Bedrock AgentCore, with more than ninety backend tools reached through MCP under the user's own credentials, human approval before destructive changes, and an Arize evaluation pipeline in CI ([case study](https://vindler.solutions/case-studies/multi-agent-systems-architecture)). Typeform's Director of AI Engineering reviewed the work on [Clutch](https://clutch.co/profile/vindler-solutions). The case study on our site is anonymised; the Clutch review names the client. Against the criteria: we have written about [when a single agent is the better choice](https://vindler.solutions/blog/multi-agent-systems-hype-vs-reality), [agent evaluation at scale](https://vindler.solutions/blog/agent-evaluation-at-scale) and [what breaks first on Bedrock AgentCore](https://vindler.solutions/blog/aws-bedrock-agentcore-production-guide). We have not published latency or cost per run for the Typeform system, which by criterion four is a gap, and our framework contributions to LangChain are small next to Vstorm's or deepsense.ai's. We build on open frameworks in the client's own cloud account and repository from the first commit. Engagement shape: a one-week fixed-price [Production Readiness Review](https://vindler.solutions/production-readiness-review) at $4,500, then projects from $25,000. Clutch shows 5.0 across five verified reviews. If you need fifty engineers or a Microsoft stack, one of the firms above is the better call. ## Also considered **Fractional AI**, now part of Ode with Anthropic, has the best public evaluation case in the market, the [Zapier work](https://www.fractional.ai/case-study/the-power-of-llm-evals-how-fractional-ai-partnered-with-zapier-to-reduce-hallucinations-by-over-80) that cut hallucinations by more than 80%, but none of its published cases is multi-agent, which is worth noting in itself. **Zartis** (Cork) published a useful [architecture review](https://www.zartis.com/success-stories/ai-architecture-for-multi-agent-system/) of an unnamed client's fourteen-agent system that scored 100% on its test sets and failed on real conversations; it is advice on fixing a system, and the client is not named. **Stride** and **Datasparq**, profiled in our [general comparison](https://vindler.solutions/blog/best-ai-consulting-firms-2026-comparison), have named agent work that is single-agent. **LeewayHertz**, the name that appears most often in these lists, builds on its own ZBrain platform and we found no named multi-agent client. ## The comparison table "Named multi-agent work" means a named client on a system with more than one agent. Prices are what the firm or its Clutch profile states. | Firm | Named multi-agent work | When one agent is enough | Numbers published | Framework code | Public price | Verified reviews | | --- | --- | --- | --- | --- | --- | --- | | Focused | Agents at Coinbase, OCS (subgraphs) | Yes, explicit rules | Routing and token comparison | No | $100K minimum, $200 to $300/hr | None | | Vstorm | Yes (Mixam, Yeeld) | Yes (agent versus graph) | Users, conversion, token cost | Yes (Pydantic AI packages) | $10K minimum, $100 to $149/hr | 4.9, 22 | | deepsense.ai | Yes (Cato Networks, on Clutch) | Not found | No | Yes (Ragbits) | $25K minimum, $100 to $149/hr | 5.0, 11 | | Caylent | Yes (CloudZero) | Yes (consolidated agents) | Latency per step | No | Not published | None | | Grid Dynamics | No (two unnamed) | Not found | No | No (own GAIN platform) | Not published | Not verified | | Cognizant | Telstra (test and deploy) | Not found | Internal ticket reduction | Yes (neuro-san) | Not published | Not checked | | Genpact | Yes (Apex Fintech) | Not found | No | No (own riskCanvas) | Not published | Not checked | | Eficode | Yes (University West) | Not found | No | No | $10K minimum, $100 to $149/hr | None | | Vindler | Yes (Typeform, on Clutch) | Yes | No | Small (LangChain) | $4,500 review; $25K minimum | 5.0, 5 | ## How to run the evaluation in a week Shortlist three firms and ask each the same questions. Would you build my system with one agent, and if not, why not. How do you measure routing accuracy, and what does your test set look like for each agent. What does one run of a typical request cost in tokens, and how long does it take end to end. Where does the orchestration run, and what do I keep if we part ways. Then ask each firm to sketch your system on a call. A firm that draws five agents before asking how many of your requests touch more than one domain has answered the first question for you. Our [guide to choosing a technical partner](https://vindler.solutions/blog/how-to-hire-ai-development-partner) covers the rest of the process, and the [general AI consulting comparison](https://vindler.solutions/blog/best-ai-consulting-firms-2026-comparison) covers firms outside multi-agent work. ## Method and corrections All facts were collected on 5 November 2026 from each firm's website, its Clutch profile where one exists, the AWS Partner Network and Machine Learning blogs, framework vendors' sites, GitHub and press. Every fact in a profile links to its source. Team sizes are the firm's own claim, its Clutch band or its filings. Where a fact could not be verified we say so. The full method shared by our comparisons is [here](https://vindler.solutions/blog/how-we-compare-ai-firms). We are one of the firms in the table, wrote our own entry to the same standard, and placed it last. If you work at a firm named here and a fact is wrong or out of date, write to [contact@vindler.solutions](mailto:contact@vindler.solutions) with "Comparison corrections" in the subject and a link to the source. We will correct it and record the change here, with the date.
