Finding an Azure consulting firm is harder than it should be, and not because there are too few of them.
Every website lists the same four services — migration, security, data, cost savings. Most directories put sponsors near the top. And a lot of the recommendations still circulating were written before the firm in question was bought by somebody else.
The largest independent Azure consultancy in the US was acquired by Cognizant in January. Neudesic is now part of IBM. Core BTS was sold and renamed NRI.
So you end up with a shortlist you cannot actually rank. Ten firms that all look qualified on paper, and no way to tell which one will put senior engineers on your project and which will send whoever was free that week — or which one is quietly a different company now.
This page tries to supply the missing part: ten US Azure firms, what each is genuinely good at, how big they are, who owns them today, and the kind of client each one suits. Details checked September 2026.
The short version
- Whether you want a project finished or systems run changes everything. Firms are built for one or the other and will happily sell you either. This is where most of the money gets wasted.
- Ownership has probably changed since you last looked. Eight well-known Azure firms have been bought or renamed in two years. Several still appear on other lists as though nothing happened.
- The service list on their website tells you almost nothing. Everyone claims the same four things. Almost nobody is good at all four.
- Size matters more than most people expect. A 13,000-person consultancy and a 30-person specialist both do good work. Only one of them will care about your project.
The first half below covers how to weigh all that up. The ten firms follow it.
How to choose an Azure partner
Do you need something finished, or something run?
This is worth settling early, because it decides most of the rest.
A project ends. The landing zone gets built. You move off VMware. The bill that doubled comes back down. Done.
Running things never ends. Monitoring, patching, on-call, somebody picking up the phone at 3 am.
Firms are built for one or the other, and they will happily sell you either. Signing a monthly contract to run your systems when six weeks of expert help would have done it is the most expensive mistake in this market — and the one we see most often.
A rough test: if you can describe what “finished” looks like in one sentence, a project is probably what you need.
Ownership has probably changed since you last looked
This matters more in Azure than almost anywhere else right now. The independent mid-sized Azure specialist is quietly going extinct.
Just look at the last two years:
- 3Cloud — the biggest independent Azure firm in the country — bought by Cognizant
- Neudesic — bought by IBM
- Core BTS — bought by a Japanese company and renamed NRI
- Quisitive and Perficient — both taken private by investment firms
- Wintellect — swallowed by Atmosera
- Hanu — swallowed by Insight
- Cloudreach — vanished into Atos so completely it now lives on a page of retired brands
None of that is automatically bad news — some of these firms are better resourced than they were. But the company you read good things about last year may now be a department inside something ten times its size, with new targets, new pricing and a different answer to “can you start in March?”
It is a fair thing to raise on a first call: who owns you, and has that changed recently? The more useful follow-up is what changed as a result.
The service list is the least useful thing on their website
Every Azure firm’s site claims migration, security, data and cost savings. Same four bullets everywhere, which makes them useless for telling anyone apart.
A narrower question tends to work better: what do you get called for?
The good answers are specific. We do mainframes alongside Azure. We are a data shop — Fabric and analytics. We do DevOps and app modernisation and not much else. Those are firms that know what they are, and they will usually tell you when your problem is not theirs.
Vaguer answers tend to sound like the website. That does not make a firm bad, but it does suggest you would be getting an average team on an average day — which is fine for straightforward work and thin cover if your problem turns out to be hard.
Size matters more than most people expect
This one gets skipped a lot, and it causes more disappointing engagements than anything except the project-versus-operations mix-up.
- A firm too big for you tends to send whoever was free that week, at rates set for companies with far more money than you.
- A firm too small for you means you become their largest client — flattering, and it puts you on the hook for the risks of their growth.
As a rough guide: under six figures of annual Azure spend, firms below 100 people are usually the better match. A serious estate spanning several business units generally wants a few hundred people behind the account. In between, either can work — which is why asking about their typical client size, and whether you would sit at the top or bottom of that range, is more revealing than it sounds.
Four questions worth asking on the call
- Who is actually doing the work?
Names, and how much of their week you get. Any firm can staff a project with two juniors and a part-time architect. Having the names written into the contract is the usual protection against it. - What are you genuinely known for?
As above — the thing to listen for is whether the answer is specific. - Who owns you, and has that changed?
Also worth knowing who owned them two years ago. - What happens in month seven?
Most Azure projects go fine for six months. Handover, whether your people can run what gets built, and what arrives in writing are the things that matter after that. A firm that goes vague here is quietly assuming you will never leave.
And one that rarely gets asked: whether they can put you on the phone with a customer your size, in your industry, from the last year. Not a logo on a slide — a call. Firms doing good work for companies like yours will usually set it up inside a week. The rest tend to offer a case study instead.
Top 10 Azure consulting companies
All ten, side by side
| Firm | Best for | Size | What sets them apart |
|---|---|---|---|
| Quisitive | All-in on Microsoft | ~500 | Microsoft and nothing else — Azure, Fabric, D365, Copilot |
| Obsium | A specific job, no retainer | Boutique | Project-based senior Azure engineering |
| Atmosera | Regulated industries | 100+ clients | Azure-only since 2014, with a real dev team |
| Ensono | Old systems that can’t go down | ~3,000 | Runs mainframes alongside Azure |
| Concurrency | Midwest mid-market | Founded 1989 | Still independently owned after 37 years |
| InCycle Software | DevOps and app modernisation | Small | Nine-time Microsoft Partner of the Year |
| NRI (was Core BTS) | Microsoft + Cisco together | Mid-size | Network and cloud handled as one problem |
| Emergent Software | Data, analytics, Fabric | Small–mid | The data specialist on this list |
| CloudServus | Smaller firms wanting licensing too | 11–50 | Licensing and engineering from the same people |
| Slalom | Outgrown a boutique | ~13,000 | Big firm that staffs from local offices |
US firms only. Global consultancies are further down. Firms that have been bought and no longer exist on their own are at the very end.
The numbers are reading order, not a ranking. One firm here has 30 people and another has 13,000. They are not chasing the same work.
Obsium is on this list, at number two. We wrote our entry the same way as the other nine.
1. Quisitive
HQ: Dallas, Texas · around 500 people Best for: Mid-sized and larger companies going all-in on Microsoft
Quisitive does not touch AWS or Google Cloud. It is Azure, Fabric, Dynamics 365 and Copilot, and that is the entire menu.
That single-vendor focus is the whole proposition. If your business runs on Microsoft end to end — cloud, data, ERP, the productivity stack — there is real value in one firm that understands how those pieces break each other.
H.I.G. Capital took the company private in March 2025. In a market where everyone is being bought by a competitor, being bought by an investor is the better version of that news.
A good fit when: your whole stack is Microsoft and you want one firm across all of it. Probably not when: you run more than one cloud and want someone who will admit when Azure is the wrong answer.
2. Obsium
HQ: Pleasanton, California, with engineers in Kochi, India Best for: Growing companies that need serious Azure help for a specific job
We do not run your systems for you. We do Azure engineering as projects that start and finish.
Five things, specifically:
- Architecture reviews. We check what you have against your own targets for uptime, security and cost, then hand you a written plan sorted by risk and effort. Findings you can act on, not a colour-coded chart.
- Landing zones built properly. New Azure setups on Microsoft’s Cloud Adoption Framework, shaped around your compliance rules, your identity setup and how your team actually works. You get infrastructure-as-code a human can read and a runbook your on-call engineer can follow at 3am.
- Migrations. Off your own servers, off AWS, or out of an Azure estate that grew sideways for five years. We plan it one workload at a time — copy it across where that is right, rebuild it where that pays for itself, and tell you which is which.
- Bills that stop surprising finance. Tagging, policy, reservations, autoscaling and budget alerts. Most clients see 20 to 35 percent come off in the first quarter.
- Identity and compliance. Entra ID, network segmentation, Defender, key management, audit logging — built against whichever framework you answer to, whether that is HIPAA, SOC 2, ISO 27001 or PCI. Controls mapped one to one, checked before go-live rather than after the auditor arrives.
We have done this for healthcare, fintech and SaaS teams. Some were clean builds. Some were inherited estates with ten years of drift and nobody left who remembered why.
What makes us different: most firms here are built to sell you a monthly service. For a lot of companies, that is the right thing to buy. But if you already have a decent platform team and one specific problem, a retainer is an expensive way to solve it.
We tend to be a good fit when: you have your own engineers and want Azure specialists working next to them. Probably not when: you want someone on call around the clock, or a team based only in the US.
3. Atmosera
HQ: Lake Oswego, Oregon · 100+ clients Best for: Mid-sized and larger companies in regulated industries
Atmosera has done Azure and only Azure since 2014 — which means it committed to the platform years before most firms took it seriously.
It also absorbed the software development and training firm Wintellect in 2021, and that matters more than it sounds. Plenty of managed service providers can keep your lights on. Fewer have actual software engineers who can rebuild an application properly while they are in there.
Most of its work is healthcare, financial services, legal, retail and public sector — industries where the compliance paperwork is as much of the job as the engineering.
A good fit when: you want an Azure-only firm with real engineering depth and compliance experience. Probably not when: you need someone across several clouds.
4. Ensono
HQ: Downers Grove, Illinois · around 3,000 people Best for: Large companies with legacy systems in the way
Ensono does something almost nobody else on this list does: it looks after mainframes. Actual mainframes, still running the business, right next to modern Azure work.
That combination is rarer than it should be. Most cloud firms will happily plan your Azure future and go quiet about the forty-year-old system that processes your payments. If you have one of those, you need a partner who will touch it.
A good fit when: you are large or regulated, with old systems that have to keep running through the move. Probably not when: your Azure estate is straightforward. You would be paying for complexity you do not have.
5. Concurrency
HQ: Milwaukee, Wisconsin · founded 1989 Best for: Manufacturers, financial firms and professional services in the Midwest
Set against the ownership churn above, one line stands out: Concurrency has been independently owned since 1989. No parent company. No investment firm.
In this market that is now unusual enough to be a feature. It means the people who decide how your project runs are the people who own the consequences, and that nobody is going to renegotiate your rates because a new owner has a margin target.
It has also won Microsoft Partner of the Year five times across fifteen years — a longer run of recognition than most firms twice its size can show.
A good fit when: you are mid-sized, ideally in the Midwest, and want a partner that will still have the same owners in three years. Probably not when: you need a national or global delivery footprint.
6. InCycle Software
HQ: Offices in Manhattan and on the West Coast · small team Best for: Mid-sized US and Canadian companies doing DevOps and app modernisation
Nine Microsoft Partner of the Year awards, most recently in 2025. From a team you could fit in a meeting room.
That only happens when a firm stays narrow. InCycle does Azure DevOps and application modernisation. Not everything. Those two things, for a long time.
Narrow is usually exactly what you want — right up until it isn’t.
A good fit when: your project is DevOps or app modernisation and you would rather have depth than coverage. Probably not when: you need infrastructure, data and security handled at once. A small team cannot be in three places.
7. NRI
HQ: US Midwest Best for: Mid-sized companies wanting Microsoft and Cisco from one place
Start with the name. This was Core BTS until April 2025, when Nomura Research Institute bought it and rebranded. Older articles still list it the old way — worth knowing before you call a number you found in a 2024 blog post.
Its distinguishing feature is covering Microsoft and Cisco together. That suits companies whose network and cloud decisions are tangled up in each other, which is most companies with a physical footprint — factories, hospitals, retail estates, anywhere the WAN matters as much as the workload.
A good fit when: your network and your cloud need handling as one problem. Probably not when: you want a firm with no other vendor loyalties.
8. Emergent Software
HQ: Minneapolis, Minnesota, with an office in Boston Best for: Smaller and mid-sized companies doing data work
If your Azure project is really a data project — and a lot of them turn out to be — this is the firm on the list built for it. Microsoft Fabric, modernising data platforms, and getting Copilot to do something useful rather than something demoable.
It took growth money from Winterbird Partners in July 2026. That is investment to expand, not a sale, so expect it to be bigger in two years.
A good fit when: your project is data, analytics or Fabric. Probably not when: you need infrastructure, networking or security. Not their patch.
9. CloudServus
HQ: Austin, Texas · 11–50 people · Inc. 5000 in 2026, 219% growth over three years Best for: Smaller companies that want licensing and Azure work from the same people
This is the smallest firm here, and the growth numbers are the reason it is on the list — 219% over three years is a firm that customers keep recommending.
It also handles Microsoft licensing alongside the technical work. If you are small, buying both from one place instead of juggling a reseller and a consultancy separately is worth more than it sounds. It is one fewer relationship, and one fewer party to blame when something is wrong.
A good fit when: you are a smaller company and want a partner your own size who can also sort the licensing out. Probably not when: you are a large enterprise. You would be their biggest client, and that suits nobody.
10. Slalom
HQ: Seattle, Washington · around 13,000 people Best for: Companies that have outgrown a boutique but do not want a global consultancy
Slalom is by far the largest firm here, and the only big one we kept — because it works differently from the others its size.
It staffs projects out of local offices instead of flying a team in on Monday and out on Thursday. That sounds like a small thing. Anyone who has been through the alternative knows it isn’t: you get people who can sit in your building, who are not billing travel, and who still work there next year.
A good fit when: you need more bench than a boutique can offer and still want people who live near you. Probably not when: you want the founders on your project. At 13,000 people, you get a good team. You do not get them.
When a global consultancy makes more sense
Nobody above will run a three-year programme across five countries while you also replace your ERP. These will, and they will charge like it.
| Firm | Known for |
|---|---|
| Accenture / Avanade | Avanade exists purely for Microsoft work — the deepest Azure bench anywhere. 20th year running as Microsoft’s Global SI Partner of the Year |
| Capgemini (with Sogeti) | Broad Azure work tied to business change |
| Cognizant | Azure app and data modernisation; healthcare and banking. Bought 3Cloud in January 2026 |
| Infosys | Azure data and AI at enormous scale |
| TCS | Migration at volume; the largest delivery machine here |
| Wipro | Azure infrastructure and industry-specific work |
| HCLTech | Infrastructure-led Azure managed services |
| Kyndryl | Getting mission-critical and mainframe systems onto Azure |
| IBM (with Neudesic) | Azure and AI for very large utilities, banks and insurers |
| DXC | Managing legacy estates; insurance and banking |
Firms you will see on other lists that no longer exist
Azure consulting has consolidated faster than almost any corner of IT. Every name below still shows up on articles published this year.
- 3Cloud — bought by Cognizant, January 2026. The largest independent Azure specialist in the US, over 1,000 Azure engineers, gone. The people are still there. The independent firm is not.
- Neudesic — now IBM Neudesic. IBM bought it in 2022 and still uses the name. But read its own page and it talks about the largest utilities, banks and insurers. A real Azure firm — just not a mid-market option.
- Core BTS — now NRI. Bought and renamed in April 2025. On our list above, under the name it uses now.
- Cloudreach — gone entirely. Atos bought it, folded it into Eviden, and it now sits on Eviden’s own page of retired brands. Which is a fairly definitive answer.
- Wintellect — part of Atmosera since 2021. Atmosera is on our list.
- Hanu — part of Insight Enterprises since 2022. No longer a separate business.
- BlueGranite and Fusion Alliance — both gone, and never the same company. Lists mix them up constantly. BlueGranite went into 3Cloud in 2022, so it sits inside Cognizant now. Fusion Alliance was bought by New Era Technology in 2023.
One more. Rackspace Technology turns up on plenty of Azure lists. In June 2026 it cut around 15% of its people worldwide and said it is deliberately stepping back from older public cloud work to chase enterprise AI. Its Azure managed services sit inside the part being shrunk. Not a firm we would point an Azure buyer at this year.
Frequently Asked Questions
How much does Azure consulting cost?
Projects are usually a fixed price or charged by time and materials. Managed services are monthly — often a percentage of your Azure bill, or a fee per server. Watch the percentage model: the partner earns more when your bill goes up. Ask how they get paid to bring it down.
Microsoft-only partner, or multi-cloud?
Microsoft-only firms usually know Azure better. Multi-cloud firms will tell you when Azure is the wrong tool. If you are committed to Azure, go specialist. If you are still deciding, do not ask someone who only sells one thing.
Do I need a partner at all?
If you already have Azure engineers and a clear problem, you might only need help with the hard part. If you have no Azure depth and live systems running, you need either a partner or a hire — and a partner is quicker to start and easier to stop.
Is a bigger firm safer?
Bigger firms are predictable and will not disappear. They are also more likely to give you whoever is free. Small firms depend on a few key people but usually give you their best ones. Neither is safer. They fail differently.
How long does an Azure migration take?
A single workload, a few weeks. A landing zone plus a first wave of applications, three to six months. A full estate with compliance requirements and legacy systems, a year or more. Anyone quoting you a timeline before looking at your environment is guessing.
