The buyers of Workday consultancies are mostly firms that live near the HR department. We have verified 38 acquisitions of Workday partners between 2015 and 2025, and the buyer list reads like an HR services directory: Aon, Alight, Mercer, KPMG, HR Path, Cielo, the payroll processor OneSource Virtual’s owners, and one listed Workday specialist, Kainos, which bought seven firms on its own. The technology giants each took one of the largest independents available and went quiet, and in 2025 the staffing groups arrived, buying at a scale the market had last seen in 2020.
The scale of that buying has one explanation: a pure Workday firm is a rare thing. Most companies with a Workday business are something else first, a Salesforce house like Appirio or an HR services firm like Ataraxis, and when such a firm sells, the Workday side is what the buyer pays for. Purely Workday firms at real scale exist in single-digit numbers, and four of them have already sold. Our partner ecosystem research places Workday at the point where scarcity peaks, the best and last window a pure specialist gets.
The Most Active Acquirers
| # | Family | 2015-19 | 2020-22 | 2023-25 | Total | Type and ownership |
|---|---|---|---|---|---|---|
| 1 |  Kainos |
2 | 5 | 0 | 7 | Workday specialist; listed (LSE: KNOS) |
| 2 |  Alight |
4 | 0 | 0 | 4 | HR outsourcer, ex-Aon Hewitt; Workday arm sold to H.I.G. 2024, now Strada |
| 2 |  Accenture |
2 | 2 | 0 | 4 | Global integrator; listed (NYSE: ACN) |
| 4 |  Cognizant |
1 | 2 | 0 | 3 | Global integrator; listed (NASDAQ: CTSH) |
| 4 |  Mercer |
3 | 0 | 0 | 3 | HR consultancy; Marsh McLennan |
| 4 |  HR Path |
1 | 0 | 2 | 3 | French HR services group; Ardian and management |
| 7 |  KPMG |
1 | 1 | 0 | 2 | Big Four; partnership |
Kainos bought its seven between 2019 and early 2022 and has been quiet since. Alight’s four run from Kloud in 2015, bought while it was still Aon Hewitt, to three additions in 2019, after which it sold the whole arm to private equity. Cognizant’s three include one of the largest Workday partners in Asia Pacific, which arrived inside Collaborative Solutions. HR Path adds a fourth, Lumi, in early 2026, and the other twelve buyers each appear once.
Kainos is the one buyer that fits no group. The listed specialist consolidated this market deliberately, seven purchases between 2019 and early 2022, from Formulate in the UK to Planalyse in the Netherlands, four of them Adaptive Planning firms. It has bought nothing since early 2022. A specialist buys again when it needs capability it lacks, so it stays on a seller’s list even quiet.
The Four Kinds of Buyer
HR, Payroll and Accounting Firms
Firms that already serve the HR and finance functions made 13 of the 38 deals, the largest group, and they are the one kind that keeps coming back. A Workday unit slots into services they already sell, so they pay for the client book and the recurring support underneath it. For a seller whose firm is an HR business with Workday inside, this group is the natural first call. Select transactions include the following:
- Aon bought Kloud, then one of the largest dedicated Workday firms outside the US (2015)
- Mercer bought everBe, a leading French Workday partner (2018)
- Alight bought Wipro’s Workday business for about $110M (2019)
- KPMG bought DayOne Consulting in Canada (2022)
Technology Giants, Then Silence
IBM, Wipro, Accenture, Cognizant and Deloitte each took one of the largest independents available at the time, and Accenture and Cognizant added smaller purchases around theirs, the family counts in the table above. Apart from one software tuck-in, none has bought since 2022, and the majors without a Workday arm, TCS and HCLTech among them, have been signing partnership agreements since 2024 instead of buying. For the owner of a large, mostly pure Workday firm this is the group most capable of paying for scale, and it moves slowest. Select transactions include the following:
- IBM bought Meteorix (2015)
- Wipro bought Appirio for $500M (2016)
- Cognizant bought the 1,000-person Collaborative Solutions for about $385M (2020)
- Accenture bought Sierra-Cedar’s Workday business (2020)
- Deloitte bought SimplrOps, a Workday, SAP and Oracle operations software firm (2025)
Staffing Groups
Staffing groups already place Workday consultants with the same clients, and buying a consultancy converts that placement business into owned, recurring services revenue. They price certified headcount and growth, and they already know the targets from placing consultants beside them. Select transactions include the following:
- ASGN bought TopBloc for $340M (2025)
- Red Global bought LRB Group (2026)
Private Equity
Sponsors enter this market twice over: buying platforms outright and giving founder-owned firms their first institutional capital, then selling to the strategic buyers years later. Every sponsor that built a Workday platform has either exited or is holding. Select transactions include the following:
- TCV bought OneSource Virtual for $150M (2015)
- BV Investment Partners backed TopBloc (2020)
- WestView recapitalized Invisors (2021)
- TA Associates took the majority of OneSource Virtual (2026)
Deal Volume and Geography
The market peaked at seven deals in 2022, went almost silent through 2023 and 2024 while rates rose and the platforms digested, and restarted in 2025 with a different kind of buyer. The first half of 2026 alone brought nine more deals, more than any full year in the chart, so the restart is accelerating.
Three of every five targets were American. Continental Europe has produced seven deals across six countries, three of them bought by HR services groups, Mercer twice and HR Path once, with Kainos taking three and Kognitiv one, so a European owner’s realistic buyer list starts with the HR consolidators, and the scarcity of European Workday firms works in the seller’s favor.
What Workday Partners Sell For
Five of the 38 deals have a public price, and one adjacent transaction sits beside them.
| Target | Buyer | Year | Price | Note |
|---|---|---|---|---|
| Appirio | Wipro | 2016 | $500M | Salesforce house carrying a Workday arm |
| Collaborative Solutions | Cognizant | 2020 | ~$385M | pure Workday, about 1,000 people |
| TopBloc | ASGN | 2025 | $340M | pure Workday, around $150M revenue |
| OneSource Virtual | TCV | 2015 | $150M | Workday payroll and BPO partner |
| Wipro’s Workday business | Alight | 2019 | ~$110M | carve-out of the Appirio Workday business |
| Alight’s payroll and deployment arm | H.I.G. Capital | 2024 | up to $1.2bn | carve-out, outside the 38-deal population |
All are platform trades, so they mark the ceiling, and everything below it sells privately.
For the rest of the market the reference is our IT services valuation multiples research, 1,051 deals at a median of 1.1x revenue and 10.4x EBITDA on a median size of about $21M. Purity moves a Workday business up that range more than anything else, because certified Workday capacity cannot be built quickly and the firms that have it in concentrated form are nearly gone. After purity, buyers price the share of recurring post-production support, which is what the HR consolidators pay for, and Adaptive Planning depth, the capability Kainos collected four times.
Who Buys Next
The historical list is backward-looking, and most of the firms on it have stopped. Who buys next is a judgment call, and we make it on four signals: the pace of a buyer’s recent deals, the date its sponsor invested, the plans it has stated, and the capabilities it still lacks. These are the buyers showing those signals in mid-2026.
| Buyer | Why next | What they would buy |
|---|---|---|
| HR Path | four Workday deals through Lumi in February 2026, the steadiest buyer in the market | HR-led Workday firms in Europe and the United States |
| ASGN | TopBloc in February 2025, with placement revenue across the ecosystem still to convert into owned services | pure Workday consultancies with certified headcount |
| TA Associates | a majority of OneSource Virtual taken in January 2026, a platform at the start of its hold | services and payroll add-ons for the platform |
| UST, Embark and Argano | each entered in 2026, with Intecrowd, Commit and Stormloop | tuck-ins that scale a new Workday arm |
| Kainos | seven purchases through early 2022, then quiet, and a specialist buys again when it needs capability | firms holding capability or coverage it has yet to collect |
| The HR consolidators (Mercer, KPMG, Strada) | thirteen deals by firms serving the HR function, the group that keeps returning | Workday units inside broader HR and accounting firms |
| Rotation Digital | Syssero in January 2026, the seed of an HR-tech services group | Workday consultancies and adjacent HR-tech firms |
The list is up to date as of the time of writing.
What This Means for Sellers
The buyers who pay most buy rarely, and the buyers who buy most often are HR services firms a technology owner might never think to call. A pure Workday firm sells into scarcity, with the 2025 and 2026 buyers competing for it. A Workday unit inside a broader firm sells best to the HR and accounting consolidators, who have bought thirteen times and keep coming back.

Method and Sources
This page counts differently from its siblings, and says so. Workday services M&A is the worst-recorded market we cover: our deal database, built on Mergermarket and extended by our verification, holds 22 of these transactions, and a further 16 are verified directly from the acquirers’ own announcements, each named in the text. The figures on this page, including the ranking, the yearly chart and the country chart, draw on all 38 verified deals 2015-2025, because a records-only version would misstate the market by more than 40 percent. Counts consolidate corporate families under today’s owner: Kloud counts under Alight via Aon Hewitt, Decisif under Accenture via DayNine, Theory of Mind under Cognizant via Collaborative Solutions. Appirio counts as a 2016 deal under Wipro, and the 2019 sale of its Workday business to Alight is a separate transaction that counts under Alight. Acquisitions by Workday itself, Workday Ventures investments, minority stakes and the Alight-to-H.I.G. carve-out that created Strada sit outside the population. One counted target, SimplrOps, is operations software rather than a consultancy. Five deals carry a public price, and the Collaborative and Wipro figures are reported by financial media rather than the parties. The 2026 transactions are listed as market context and excluded from every count. The Who Buys Next section is our judgment from the signals named there, not a count from the database, and it is up to date as of the time of writing.
