Ciesco: M&A Advisory Firm for Media, Tech, Marketing

Ciesco is a London-based M&A advisory firm that specializes in mergers and acquisitions for the technology, media and marketing sectors, advising entrepreneurs, corporates and private equity firms on sell-side and buy-side transactions. Founded in 2011, Ciesco's own 2025 annual review reported 2,308 completed deals across its core sectors that year, with disclosed deal value, excluding mega-deals, rising 61.8% year over year to $91.1 billion.

What does Ciesco specialize in?

Ciesco covers four sectors: technology and data, media and marketing, healthcare, and sustainability, according to the firm's own sector pages. Within media and marketing, Ciesco's coverage spans digital agencies, marketing technology platforms, digital media companies and creative agencies. The firm describes its work as helping shareholders and management teams navigate the fusion of technology, data, digital and content reshaping the media and marketing sectors.

Ciesco also runs a technology and data practice covering application software, DevOps, financial software and cybersecurity. That practice frequently overlaps with its media and marketing mandates, since marketing technology deals increasingly involve software and data assets rather than pure agency services.

How is Ciesco structured?

Ciesco pairs senior industry practitioners with sector specialist investment bankers, rather than staffing deals with generalist corporate finance teams. That combination gives the firm direct relationships at the C-suite level inside strategic acquirers, private equity firms and growth investors, according to Ciesco's own description of its approach.

The firm also runs an executive search practice alongside its M&A advisory work, sourcing C-suite executives, board directors and non-executive directors for clients across its covered sectors. Ciesco positions this combination, deal advisory plus search, as part of what differentiates it from generalist investment banks that only execute transactions.

What M&A deals has Ciesco completed?

Ciesco has advised on hundreds of transactions since its founding, with recent mandates spanning growth investments, acquisitions and sell-side processes across its media, marketing and technology coverage.

Client testimonials published on Ciesco's own site describe deal teams that stayed engaged from the start of a process through to completion, including on cross-border transactions involving buyers such as Banyan Software.

What does Ciesco's research show about media and marketing M&A?

Ciesco publishes an annual Global M&A Review covering technology, media and marketing. The 2025 edition, released in February 2026, recorded 2,308 completed transactions in 2025, a 12.6% decline year over year but still about 17% above 2020 levels.

The prior year's review found Agency Services & Strategy was the highest-growth media and marketing segment in 2024, up 32% year over year. That same report cited Netflix's announced acquisition of Warner Bros, Omnicom's $15.9 billion acquisition of IPG, and Silver Lake's $13.0 billion acquisition of Endeavor Group as evidence of large-scale consolidation returning to the sector in 2025.

Ciesco's 2025 data shows private equity represented 54% of transactions that year, driven by platform-led buy-and-build strategies, while strategic buyers accounted for 69% of all deals and financial sponsors made up 31%. Take-private activity reached $154.8 billion in announced deal value across 2025, according to the same review.

Why does Ciesco matter to marketing and PR M&A?

Ciesco matters to Everything-PR's audience because it publishes independent, sourced deal data on the same media and marketing M&A market that PR and communications agencies increasingly sit inside, as marketing services, digital agencies and communications firms consolidate. That research function means buyers and sellers in the PR and communications space can benchmark valuations and deal volume against a market-wide dataset rather than relying on a single advisor's pitch.

The Connective3 and AiVidens mandates also show Ciesco working on deals that blend marketing services with software and data, a pattern Everything-PR expects to recur across the martech and adtech specialty as more agency-adjacent transactions involve a technology component.

Which Everything-PR M&A specialty categories fit Ciesco?

Ciesco fits several specialty categories in Everything-PR's M&A directory rather than a single one. Its media and marketing coverage places it under Marketing Services M&A and Media M&A, while mandates like the AiVidens and RecVue transaction also qualify it for MarTech and AdTech M&A. Ciesco's technology and data practice additionally gives it relevance to broader digital M&A coverage beyond marketing services specifically.

How does Ciesco compare to other firms in this directory?

Ciesco is one of the more technology-leaning firms in Everything-PR's M&A directory, given its combined coverage of technology and data alongside media and marketing. That distinguishes it from directory entries such as Berkery Noyes' M&A advisory practice, an older, US-based specialist with a narrower focus on media, marketing and information industries. Later entries in this directory, including JEGI LEONIS, SI Partners and AdMedia Partners, will let readers compare how each specialist firm positions itself within the advertising, marketing and PR M&A market.
