Boards keep asking the same thing this year: hire internally or bring in people who’ve already done this elsewhere? AI rewrites roadmaps faster than most teams can staff, and budgets haven’t kept up with the hype. That’s the gap advisory firms now fill.

Here are seven advisory firms worth knowing, what each one’s actually good at, and how to spot a real fit versus a polished pitch deck.

Why External Teams Keep Getting the Call

Building a transformation team from scratch takes months you don’t have. Hiring the wrong outside firm costs more — rework, delays, a board that stops trusting the roadmap. So leaders rent the expertise instead. Makes sense, doesn’t it?

A few things push this harder than usual right now:

  • AI adoption jumped from pilot projects to board mandates almost overnight.
  • Legacy ERP systems age out faster than internal IT can rebuild them.
  • Cloud and data talent are scarce and pricey to keep on the payroll year-round.
  • Rules like the EU AI Act demand specialist knowledge nobody wants full-time.

A six-person internal team can run past seven figures a year once overhead’s added in. An eighteen-month engagement with a clear deliverable often costs less and moves faster. Not guaranteed. Common enough, though, that CFOs ask for it by name.

Companies Worth Knowing

DXC Technology

DXC’s Advisory arm covers strategy, finance and risk, M&A, operations, and tech transformation for C-suite leaders at large and mid-market firms. Consultants lean on AI-driven analytics rather than generic frameworks, remaining neutral across cloud and ERP vendors. The current focus is on closing what DXC calls the “AI execution gap” — moving past strategy decks into measured value. 

Endava

Endava went public on the NYSE in 2018, and its name still means one thing in banking: payments engineering done right. Delivery centers stretch from Romania to Colombia. Core banking replatforming, API-first architecture, fintech rebuilds under real regulatory deadlines — that’s the daily work. Smaller than the giants. Faster where it counts.

Globant

Started in Buenos Aires, now an S&P 500 company — Globant pairs entertainment-industry creativity with enterprise AI delivery. It’s a “Studios” group of specialists by domain rather than a generic vertical, and the client list includes major media and consumer brands. AI Studio, its generative AI unit, drives a growing share of new contracts.

Sopra Steria

France’s Sopra Steria built its name in government work — identity systems, payment infrastructure, defense IT across several European states. Large-scale ERP and cybersecurity programs for ministries and banks are routine, not exceptions. Less flashy than newer competitors. But its compliance record in regulated sectors is genuinely hard to beat.

Reply

Reply isn’t really one company. It’s a network of over ninety specialized firms under one Italian holding, each covering a narrow slice — conversational AI, SAP migration, IoT. That structure lets clients pull in a niche team instead of a generalist army. Automotive and telecom clients across Europe use it for fast, targeted work.

Zühlke

Zurich-based Zühlke built its name on product engineering, not slideware — medtech devices, industrial IoT, embedded software that actually ships. Smaller teams, longer client relationships, fewer subcontractors swapped in mid-project. Diagnostics platforms and connected manufacturing systems across the DACH region quietly bear its fingerprints.

Netcompany

Copenhagen’s Netcompany became the default partner for Nordic public-sector digitization — tax platforms, immigration systems, and welfare administration. Its low-code delivery platform moves faster than typical government procurement processes allow, which is part of why it’s now expanding into the UK and the Netherlands.

Picking the Right Partner

A shortlist full of recognizable logos doesn’t mean much. A few questions cut through fast:

  • Do they staff teams in your region, or is “global” just a slide?
  • Can they name a client in your industry, not a vague case study?
  • Do they bring their own tools, or mostly headcount?
  • How’s the contract priced — fixed scope, time and materials, or outcomes?
  • Who keeps the knowledge once the engagement ends?

What Actually Matters Here

Size on a website means little once the contract’s signed. What counts: real regional delivery, named references in the right industry, a straight answer on who owns the knowledge afterward. AI accelerators — Globant’s AI Studio, DXC’s AdvisoryX, Reply’s specialized AI units — are turning into the real differentiator in 2026, more than headcount ever was.

FAQ

Is a smaller firm riskier than a global consultancy? Not really, as long as it has a genuine regional presence.

How long do these engagements usually run? Twelve to eighteen months for a defined scope; government work stretches longer.

Fixed-fee or time and materials? Fixed fee for well-defined scopes. Time and materials for projects still taking shape.

Do these firms specialize or span industries? Both, but each has one or two sectors where the track record is strongest.

The most common hiring mistake? Choosing based on brand recognition alone, instead of checking delivery capacity close to home.
