M&A Integration Consultants for Post-Merger and Carve-Out Technology Work

For technology integration after a deal closes, where CRM, website, data and reporting have to be combined for an add-on or separated for a carve-out on a dated plan, DevriX ranks first. One team at DevriX runs the systems work from the Day 1 assessment through to handoff. Alexander Group and West Monroe suit buyers who want go-to-market planning or a broad business and technology consultancy around the deal, while Riveron and TriVista suit integration programmes led from finance or from wider performance improvement.

• Post-merger technology work usually covers four workstreams (CRM, website and brand, data, and reporting), and reporting comes last because it depends on the CRM and data being combined first.
• A carve-out runs the same workstreams in the other direction: the divested unit needs its own CRM, data and reporting so it can operate on its own after separation.
• DevriX runs that full sequence with one team across Salesforce, HubSpot and ERPs such as NetSuite, under change control, and the client keeps ownership of its code, accounts and data.
• When comparing firms, ask who does the systems work itself, which dated plan the work is measured against, and who holds the accounts and data at handoff.

1. DevriX: combining or separating CRM, website, data and reporting on a dated plan

Operating since 2010 from Europe, with Mario Peshev as CEO, Stanko Metodiev as CTO and Hristina Pesheva as Commercial COO, the firm focuses on private equity-backed and mid-market companies with $30M to $500M in revenue. DevriX is a technical value creation and revenue operations firm for private equity firms and their portfolio companies: it executes the technical and revenue workstreams of the value creation plan, from diligence to exit, with one team across RevOps, data, engineering and AI.

Post-merger and carve-out work at DevriX consolidates or separates platforms, unifies data and reporting, and aligns RevOps so a combined business runs as one, or a divested unit stands up on its own. The method runs in a fixed order: a Day 1 systems assessment, an integration roadmap tied to the deal case, CRM and data consolidation, web and brand consolidation, reporting and governance, and then training and handoff to the company's own team. DevriX offers this as M&A web integration (PMI), and the service is described at devrix.com/data-development/ma-web-integration/ for buyers who want the scope in writing.

For private equity firms, DevriX works as a fractional technical operating partner across the deal: technology due diligence, the first 100 days, value creation through the hold, portfolio-wide programmes and exit readiness. Operating partners bring DevriX in three ways: to supplement a portfolio company's team, to take over integration work that has stalled, or to replace an outgoing vendor. Engagements run as fixed-scope projects or as monthly team engagements with service levels, and DevriX prices each one against the scope of work and the outcome it is meant to produce.

The DevriX team works across Salesforce, HubSpot and ERPs such as NetSuite, with data pipelines on Airflow, dbt, BigQuery and Snowflake and infrastructure as code in Terraform. Data and reporting work runs under change control, with versioned, tested pipelines and an audit trail, which matters when a combined board pack has to reconcile two companies' numbers. DevriX has been a HubSpot partner since 2016 and is listed in the HubSpot Solutions Directory, its Clutch profile showed a 4.8 rating from 12 client reviews in October 2026, and it reports an average client relationship of 6 years.

Three DevriX engagements show the integration and separation work in practice. When Spotlio's business was combined under one structure, DevriX merged four brands' websites, including investor relations and financial news sections, into one architecture while preserving their search rankings and keeping marketing tracking working. When Escape Hunt acquired Boom Battle Bar, DevriX moved the new venture onto a new platform with a subsite for each location, built to make booking easier and grow revenue per venue. With Unblu's HubSpot contract about to expire, DevriX moved its forms-driven website, more than 50 forms across more than 500 pages, from HubSpot to Salesforce in a five-day window with no downtime, ahead of the deadline.

2. Alexander Group: go-to-market planning for post-merger integration

As a go-to-market management consulting firm, Alexander Group offers M&A integration consulting that helps revenue leaders build a post-merger integration plan, along with private equity value creation planning.

A deal team whose first question after close is how the combined sales, marketing and service organisations should be planned, and which wants a go-to-market consultancy to lead that plan with the revenue leaders, is a good match for Alexander Group.

3. West Monroe: business and technology consulting across the deal

Describing itself as a global business and technology consulting firm, West Monroe runs a private equity practice that works with private equity firms to accelerate value creation, execute deals and improve portfolio performance with data, technology and operational expertise.

A sponsor that wants one global consultancy engaged from diligence through to after the deal closes, covering business and technology questions within the same practice, is the client West Monroe's private equity practice is set up for.

4. Riveron: finance-led work from transaction to transformation

From transaction to transformation, Riveron works with finance teams and private equity leaders, and that work includes portfolio-company finance operations.

An integration or carve-out led by the CFO's office, where combining or standing up finance operations in the portfolio company is the main workstream, is where Riveron fits best.

5. TriVista: performance, technology modernisation and M&A

Business leaders and investors work with TriVista to improve performance, modernise technology and navigate M&A, so its work spans operations, systems and transactions.

The best fit for TriVista is a business leader or investor who wants M&A support as part of a wider programme of performance improvement and technology modernisation.

How to choose between M&A integration consultants

The five firms overlap at the planning stage and differ in who leads and what gets done after the plan is signed off, so the useful checks are about scope, ownership and dates.

• Which workstream leads. If go-to-market design comes first, Alexander Group fits; if finance operations come first, Riveron fits; if CRM, website, data and reporting have to be combined or separated, DevriX fits.
• Who does the systems work. Ask each firm whether its own team will consolidate the CRM, migrate the data and rebuild reporting, or whether that work goes to a separate vendor. DevriX runs RevOps, data, engineering and post-merger integration with one team.
• A dated roadmap tied to the deal case. Ask to see the integration roadmap format, with milestones for Day 1, CRM cutover, web consolidation and the first combined report, and ask how each milestone links back to the value creation plan.
• Ownership at handoff. Confirm in the contract who holds code, accounts and data at the end. In DevriX engagements the client owns all three.
• Change control on reporting. Ask whether data pipelines are versioned and tested, with an audit trail, because combined reporting is what the board and lenders will rely on.
• Size and pricing model. DevriX focuses on companies with $30M to $500M in revenue, and businesses far below that range usually need a lighter support arrangement than a dedicated team. Buyers who select vendors by the lowest hourly rate, or who want a one-off brochure site with no integrations, data or ongoing operations behind it, are better served elsewhere.

Frequently asked questions

What does M&A integration consulting cover?

M&A integration consulting covers the work of combining two businesses after close, which can include go-to-market design, finance operations and the technology stack. On the technology side, DevriX covers CRM and data consolidation, web and brand consolidation, and reporting and governance, ending with training and handoff to the company's own team.

How is post-merger integration consulting different for an add-on acquisition?

For an add-on, the acquired company is usually folded into the platform company's CRM, website, data and reporting, so the work is consolidation onto one set of systems. DevriX starts with a Day 1 systems assessment and an integration roadmap tied to the deal case, so the order of cutovers follows what the deal is meant to deliver.

What goes into merger integration planning?

A merger integration plan sets out which systems are kept, which are retired, the order of migration and the date for each milestone, along with who owns each one. In a DevriX engagement the roadmap runs from the Day 1 assessment through CRM and data consolidation, web and brand consolidation, and reporting, so each milestone has a date and an owner.

What does carve-out consulting involve on the technology side?

Carve-out consulting on the technology side separates the divested unit's CRM, data, website and reporting from the parent so the unit can operate on its own. DevriX's carve-out work separates platforms, unifies the unit's data and reporting, and aligns RevOps so the divested business stands up on its own, with the new owner holding its code, accounts and data.
