SaaS M&A weekly: 13 deals, May 19–26, 2026

Fourteen SaaS M&A deals closed or were announced in the seven days ending May 26, 2026 — spanning cybersecurity, fintech, procurement, health-tech, HCM, e-commerce, digital signage, and federal IT. Only three disclosed transaction values. The rest stayed private, consistent with how most SaaS deals are structured.

Two things stand out this week. First, AI agent governance became a stated acquisition thesis for three separate cybersecurity buyers simultaneously — Zscaler, Akamai, and Proofpoint each moved on a target whose core value proposition centers on securing or governing AI agents. Second, a cluster of platform consolidators — Coupa, NMI, and Swoop — each completed deals that extend their stacks not just wider but deeper, from feature addition toward fully autonomous workflows.

What follows is a deal-by-deal breakdown, organized by vertical cluster.

Cybersecurity and AI governance

The week's most concentrated activity was in security. Three buyers, three separate targets, one shared thesis: traditional perimeter and identity controls cannot keep up with AI agent proliferation.

Akamai to acquire LayerX for ~$205M

On May 21, Akamai Technologies (NASDAQ: AKAM) signed a definitive agreement to acquire LayerX Security for approximately $205 million, with the deal expected to close in Q3 2026. 1

LayerX is a Tel Aviv-based startup founded in 2021. Its product is a browser extension that adds enterprise security policy enforcement to Chrome, Edge, Firefox, and agentic browsers including Atlas and Comet. The company is projected to reach approximately $10 million in ARR by year-end 2026. 2

The strategic reasoning is direct: Akamai's customers are adopting AI tools faster than their existing controls can monitor. Mani Sundaram, Akamai's EVP/GM for Security Technology, put it plainly:

"Our customers are adopting AI at record speed, and they're telling us the same thing: Their existing controls cannot see how employees are interacting with AI tools and sharing with large language models. LayerX gives us a control layer at the point of use, enabling enterprises to move at AI speed without compromising safety or compliance." 2

Or Eshed, LayerX's CEO, will join Akamai's Zero Trust organization after closing. The deal is Akamai's fourth cybersecurity acquisition in Tel Aviv in five years. At roughly 20x projected ARR, the price is at the high end of early-stage security exits.

Zscaler to acquire Symmetry Systems

Also on May 21, Zscaler (NASDAQ: ZS) announced intent to acquire Symmetry Systems, a San Francisco-based company whose access graph technology maps how human and non-human identities, applications, and data connect across an enterprise. 3 The transaction was expected to close within days of announcement. No price was disclosed.

Symmetry's technology originated from DARPA-funded research at the University of Texas at Austin. The access graph ingests enterprise-wide logs and uses AI to build a continuous, real-time map of identity-to-data relationships — specifically designed to handle the explosion of non-human identities (service accounts, API keys, AI agents) that traditional identity governance tools weren't built for.

Jay Chaudhry, Zscaler's chairman and CEO, framed the acquisition in terms of obsolescence:

"As enterprises rapidly adopt AI, the old playbook for governing access built around users and directories cannot scale to millions of AI agents." 3

Mohit Tiwari, Symmetry's CEO, will join Zscaler. O'Melveny & Myers advised Symmetry Systems. Neither venture funding totals nor ARR were publicly disclosed.

Proofpoint acquires Acuvity

On May 25, Proofpoint — a Thoma Bravo portfolio company taken private in 2021 for $12.3 billion — acquired Acuvity, an AI-native runtime security and governance company, to expand its portfolio into AI agent protection and generative AI governance. 4 The deal was widely reported by security-focused outlets, though as of May 27, no official Proofpoint press release had appeared on the company's newsroom. Financial terms were not disclosed, and Acuvity's company background — founding year, investors, employee count — is not publicly available.

The three cybersecurity deals taken together mark a clear category formation moment. Zscaler targets the access graph layer; Akamai targets the browser control point; Proofpoint targets runtime governance. These are not overlapping bets — they reflect three distinct control planes that AI agent deployment exposes, and three separate buyers racing to own each one.

Fintech and payments

NMI acquires Dwolla

Announced and completed May 19, NMI — an embedded payments infrastructure company processing more than $502 billion annually across 6.5 billion transactions — acquired Dwolla, an API-first account-to-account (A2A) payment infrastructure provider based in Des Moines, Iowa. 5 Financial terms were not disclosed.

Dwolla, founded in 2008, processes $82 billion in annual transaction volume across 126 million transactions per year and serves approximately 400 customers, ranging from small businesses to Fortune 500 companies. Known investors include Union Square Ventures, Andreessen Horowitz, Thrive Capital, and CME Group, though exact round sizes and total funding raised remain unconfirmed.

The combined entity processes close to $700 billion in annual transaction volume. 6 Dwolla CEO Dave Glaser joins NMI as Chief Operating Officer, with approximately 60 Dwolla employees folding into NMI.

NMI CEO Steve Pinado positioned the deal as an infrastructure extension rather than a capability bet:

"This acquisition is a continuation of our strategy to build the most robust, white-label, embedded payments platform for our channel and enterprise partners. Dwolla gives us modern, API-first A2A infrastructure that strengthens our ability to help businesses accept, manage and move money across more use cases and more rails." 5

This is NMI's sixth acquisition in recent years — following Sphere (2023) and Agreement Express (2022) — and it moves the platform closer to a comprehensive money-movement stack covering card acceptance, bank rails, real-time payments, and FedNow.

Visma acquires Dootax and Pag Útil

Announced May 13 — just ahead of this week's window — Visma's acquisition of two Brazilian SaaS companies, Dootax and Pag Útil, is included here as it was widely surfaced in the week's deal coverage. Visma is the Norway-headquartered provider of mission-critical business software with €2.8 billion in 2025 revenue, backed by Hg Capital. 7 Financial terms were not disclosed for either deal.

The timing is deliberate. Brazil is mid-transition through a landmark constitutional tax reform that consolidates five taxes into a dual-VAT system over seven years — a compliance burden that forces businesses to retool their tax and payment infrastructure repeatedly through the transition window.

Dootax, founded in 2018 and based in São Paulo, provides fiscal automation for approximately 1,000 clients via a proprietary robotic process automation (RPA) engine built specifically for Brazil's tax system. Pag Útil is a fintech specializing in B2B payment solutions for federal, state, and municipal tax settlements. Together they create an end-to-end platform connecting tax compliance to financial execution. The Pag Útil closing remains subject to approval by the Brazilian Central Bank.

This is Visma's third Brazilian acquisition in 12 months, following Conta Azul and MaisMei. Steffen Torp, Visma's Chief Commercial Officer, said the pair have "built highly complementary, mission-critical capabilities in tax automation and payment execution." 7

Procurement, HCM, health, and other verticals

Coupa acquires Tonkean

On May 21, Coupa — the Thoma Bravo-owned spend management platform with approximately 3,500 buyers and 10 million suppliers on its network, taken private in 2023 for $8 billion — acquired Tonkean, an AI-native intake and orchestration platform. 8 Financial terms were not publicly disclosed; Israeli media outlet Calcalist estimated the deal at "hundreds of millions of dollars." 9

Tonkean, founded in 2015 and headquartered in Palo Alto with R&D in Tel Aviv, raised approximately $84 million in venture funding, including a $50 million Series B in 2021 at a roughly $300 million valuation led by Accel. Its platform offers a 100% no-code process builder, 250+ native connectors, a natural language interface, and a multi-agent orchestration framework. The company claims the platform increases user adoption by 2.2x, reduces cycle times by 50%, and saves operations teams more than 30 hours per week.

This is Coupa's fourth strategic acquisition in its push toward what it calls an "agentic trade network," following Cirtuo (sourcing intelligence), Scoutbee (supplier discovery), and Rossum (document understanding). Coupa's CPTO Salvatore Lombardo described the assembled stack as:

"A $10 trillion data foundation, eyes to read any document, intelligence to source smarter, and now the ultimate engine to orchestrate modern, agentic work." 8

Kirkland & Ellis advised Coupa; Fenwick & West and Cascadia Capital advised Tonkean. Sagi Eliyahu, Tonkean's CEO, and the team will continue operating independently within Coupa.

Coupa's fourth agentic trade network acquisition closes the loop from data to autonomous execution 8

Swoop acquires Nimble

On May 26, Swoop — an AI-driven healthcare engagement platform — acquired Nimble, a digital-first prescription management platform serving 16 million patients across independent pharmacies in all 50 states. 10 Nimble is currently the third-largest pharmacy network in the US after CVS and Walgreens. Financial terms were not disclosed.

Nimble's platform handles prescription filling, refilling, payment, and management — with digital interventions that improve medication adherence by 26–40%. The deal extends Swoop from patient and healthcare professional (HCP) engagement into prescription fulfillment, closing the loop from awareness to dispensing.

Swoop CEO Ron Elwell stated the goal is more ambitious than the deal size might suggest:

"Right now [Nimble] is the third-largest pharmacy network in the country, after CVS and Walgreens. And we think that working with Talha, we can make it the largest pharmacy network in the country." 11

The acquisition follows Swoop's January 2025 purchase of MyHealthTeam, which brought 60+ condition-specific patient communities into the platform.

Vertiseit acquires Scala for SEK 265M (~$25M)

On May 20, Vertiseit AB (VERT B, Nasdaq First North Stockholm) — a Swedish in-store experience management platform with approximately 270 employees and SEK 676 million in FY2025 net revenue — acquired Scala from the STRATACACHE Group. 12 The purchase price was approximately SEK 265 million (~$25 million at current rates), financed through an expanded credit facility with Nordea Bank and a SEK 182 million directed share issue.

Scala was founded in Norway in 1987, is headquartered in Malvern, Pennsylvania, and has been part of STRATACACHE Group since 2016. It is widely recognized as the pioneer of the global digital signage industry, serving 100+ partners and 1,000+ brands across fashion, automotive, airports, grocery, and QSR. The deal adds approximately SEK 85 million in ARR and SEK 200 million in total revenue on a full-year basis.

The acquisition thesis is a SaaS conversion play: Scala has historically operated on perpetual licensing, and Vertiseit's Dise subsidiary intends to migrate the product toward a modern SaaS-based, device-agnostic model. Vertiseit has achieved a 48% CAGR in ARR from 2012 to 2025, and the company expects synergies to be fully realized during 2026 at a target Cash EBITDA margin of 35%. DNB Carnegie raised its Vertiseit fair value range to SEK 61–80 from SEK 53–75 following the announcement. 12

Other deals: NTT DATA, Argano, Vibrint, CyberFolks/Shoper, Toptal

NTT DATA acquires WinWire (announced May 20): NTT DATA — headquartered in Tokyo, with 190,000 employees across 70+ countries and more than $30 billion in annual revenue — signed a definitive agreement to acquire WinWire, a Santa Clara-based Microsoft consulting firm. 13 WinWire was founded in 2007, employs 1,000+ people with delivery centers in India, and holds six Microsoft Partner of the Year awards. The deal strengthens NTT DATA's global Microsoft Azure practice (24,000+ certifications across 50+ countries) and adds WinWire's proprietary "Agentic AI @ Scale" framework for moving enterprise clients from AI pilots to production deployment. Rothschild & Co served as financial advisor to NTT DATA. Terms were not disclosed.

Argano acquires Ascend (announced May 12, borderline to this window): Argano — a digital transformation firm based in Plano, Texas — acquired Ascend, a UKG services partner founded in 2003, with 130+ certified consultants and 300+ active projects. 14 This is Argano's 12th acquisition since its April 2025 strategic growth initiative, and its 28th overall since founding in 2020. The deal advances Argano's stated goal of building the largest UKG practice globally. Kirkland & Ellis and Ernst & Young advised Argano; Crowe LLP and Smith, Gambrell & Russell advised Ascend.

Vibrint acquires Ampsight (reported May 21): Vibrint, a federal technology services firm, acquired Ampsight to add multi-cloud, cybersecurity, and AI capabilities to its federal platform. 15 No financial terms, deal structure, or detailed target company background were publicly available. The deal was reported by TechStrat's weekly M&A roundup.

CyberFolks and Shoper announce merger (announced May 21): Poland's CyberFolks and Shoper announced a plan to merge into a single Warsaw Stock Exchange-listed entity valued at approximately €1 billion. 16 Shoper shareholders will receive 0.2281 CyberFolks shares for each Shoper share; CyberFolks will issue 3,215,165 new Series F shares. CyberFolks' existing 49.9% stake in Shoper (acquired for PLN 547.5 million, approximately $135 million, with the deal closing in January 2025) is excluded from the exchange.

The combined entity will encompass Shoper (Poland's leading e-commerce SaaS for small businesses, with PLN 21 billion — roughly $5.2 billion — in 2025 omnichannel GMV, up 45% year-over-year), PrestaShop (which CyberFolks acquired for €53.765 million in February 2026, with 230,000 active stores and €22 billion in annual GMV), and Sylius. Combined GMV across Shoper and PrestaShop exceeds €27 billion annually. Shoper will be delisted from the Warsaw Stock Exchange upon completion. The deal requires shareholder approval at both companies' General Assemblies.

Toptal acquires Adeva (announced ~May 26): Toptal — the world's largest fully remote workforce, serving 25,000+ clients across 140+ countries, founded in 2010 — announced the acquisition of Adeva, a global IT talent network connecting enterprises with vetted developers, architects, and technology consultants. 17 The deal is expected to close in Q4 2026, subject to customary regulatory approvals. Financial terms were not disclosed. Adeva's scale indicators — revenue, ARR, employee count, and funding history — were not publicly available at time of writing.
