Marketing agency deal sourcing firms, ranked.

The marketing agency deal sourcing firms worth shortlisting in 2026 serve a sector that answers unusually well, and unevenly across firms that know it. Across 54,454 emails to marketing agency owners in our owner response rates by sector research, 1.7 owners per 1,000 said yes to a conversation about an exit or a partnership, and 28% of the owners who replied were open to one, the second-highest share of twelve sectors measured. A newer cut of that same dataset, published in agency mandate origination, splits it further: owners of $5m to $50m agencies were open at 2.8 per 1,000, about four times the 0.7 per 1,000 for $10m to $500m agencies. We publish this list and DealSource Systems is our own service, so it is ranked first; the other six are ranked on fit, and every claim about them below is quoted from that firm's own live website, read in this run, and linked as the source.

A buyer with a marketing agency thesis is choosing between generalist firms that treat the sector as one line in a broad buy box, and two of the six below that actually name it. DealSource Systems runs this kind of thesis-driven outreach itself, described on how it works, which is also why it is ranked first on the list. Which of the other two name the sector, and what that gets you, is the headline finding here.

Which marketing agency deal sourcing firms actually name the sector

Two of six. Harvey & Company lists "Media & Marketing" among 32-plus served sectors, with a dedicated track record page for it. CT Acquisitions names "Marketing Agency" among 74 verticals, with its own published valuation guide for agency sellers. CAPTARGET, SourceCo, TruSight and Konverrt do not name marketing, advertising or agencies as a served vertical on their own sites; Konverrt's homepage references agencies only as clients of its own sales tooling, not as a sector it sources acquisitions in, which is a different claim.

Quick comparison

How we chose this list

We only considered firms that run owner outreach for buy-side mandates, not directories that hand over a list and leave the calling to the buyer. Every firm below states, on its own site, that it works buy-side origination for private equity, independent sponsors, family offices, or M&A advisors, and we checked each specifically for whether marketing, advertising or agencies appear as a named focus. None were current DealSource Systems clients or partners at the time of writing.

DealSource Systems

Best for: PE firms, M&A advisors and search funds who want owner conversations in a sector where the founder, not a committee, decides whether to talk.

DealSource Systems is the origination arm of Danish Lead Co, described on how it works. Pricing starts from $4,000 a month for a single thesis, no success fee, 90-day minimum, published in full. We have not published a buy-side agency acquisition case study yet, but we have run the sell-side version of this exact category twice: Agency Futures, a boutique sell-side advisory for owner-operated agencies, signed its first mandate inside 60 days and held about eight founder conversations a week for more than four months across five parallel segments, and TobinLeff, an M&A advisory for marketing and communications agencies, booked 34 owner meetings in its first six weeks. Both are evidence of how this founder population responds to a well-run outreach programme, on either side of the table. For the buy-side view of the category, see digital marketing agency acquisitions.

Harvey & Company

Best for: well-capitalised funds and corporations running buy-and-build strategies at enterprise scale, where sector depth across 32-plus generalist industries matters more than an agency-specific record.

Harvey & Company is a buy-side acquisition search and advisory firm headquartered in Newport Beach, California, serving "well-capitalized private equity funds and corporations." Its site names Media & Marketing among its served sectors and claims "1,200+ closed transactions" since 1998. Pricing is not published on harveyllc.com. DealSource Systems vs Harvey & Company sets that enterprise scale against our thesis-driven model.

CT Acquisitions

Best for: opportunistic, success-fee searches against founder-owned agency sellers, where the sector is named but sits alongside 73 other verticals rather than as a dedicated practice.

CT Acquisitions runs confidential, buyer-pays-at-close sourcing out of Sheridan, Wyoming, naming Marketing Agency among 74 served verticals and publishing its own valuation guide for agency owners. It targets "founder-owned and family-owned businesses" with "revenue typically $1M to $50M," and states fee structures vary by engagement type, with sell-side work paid at closing. Full pricing is not published beyond that on ctacquisitions.com. DealSource Systems vs CT Acquisitions weighs that success-fee model against a monthly retainer.

CAPTARGET

Best for: funds and advisors wanting volume outreach plus broker-market monitoring, where marketing agencies are one buy box among many rather than a stated focus.

CAPTARGET runs off-market owner outreach for a stated "Private equity, Corporate development, Family offices, Independent sponsors, Search funds, Buy-side advisors" client base, headquartered in San Diego, with "No Fees for Originated Deals." No marketing, advertising or agency claim appears on captarget.com. DealSource Systems vs CAPTARGET weighs its success-fee model against our retainer, a trade-off also covered in deal origination pricing.

SourceCo

Best for: buyers who want a matching platform across a defined revenue band rather than a fully managed outreach programme.

SourceCo uses AI and proprietary data to match founder-led companies in the "$2 million to $200 million" range with private equity, corporate development, search fund and family office buyers, with sellers paying nothing. Named sectors on sourcecodeals.com lean industrial, automotive and B2B services; no marketing or agency claim appears, and buyer pricing is not published. DealSource Systems vs SourceCo compares the matching model against an operator-run programme.

TruSight

Best for: funds and family offices wanting a steady subscription feed of proprietary opportunities without committing to a single sector thesis.

TruSight offers a "constant flow of targeted, proprietary acquisition opportunities," serving "professional investors, private equity funds, family office investors, and business intermediaries." No headquarters, no named sectors and no marketing or agency claim appear on trusightllc.com, and pricing is not published. DealSource Systems vs TruSight sets that sector-agnostic feed against a defined thesis.

Konverrt

Best for: an advisor or PE firm testing a marketing agency thesis before committing to a full retainer.

Konverrt runs a "deal origination engine" for lower middle market M&A advisors and PE firms targeting owner-operated businesses in the $1 million to $50 million range, with "no invoice until your first two qualified seller meetings" land. Named sectors on konverrt.com are manufacturing, construction, trades and B2B SaaS; agencies appear only as examples of its own clients, not as a sourced vertical, and no headquarters is published. DealSource Systems vs Konverrt is the closest read, since it sells the model nearest ours.

Why do marketing agency owners reply more than owners in other sectors

Because the founder is usually the asset. Clients, staff and pricing power often sit with one or two people in an agency, so the owner knows a sale will likely involve them for years through an earnout, which makes the first conversation about options rather than price. Our agency mandate origination research shows that curiosity is strongest at smaller scale: owners of $5m to $50m agencies needed 363 emails per open conversation against 1,362 for $10m to $500m agencies, and were not more annoyed when approached, just harder to reach once a management team sits between the owner and an inbound email.

That pattern held across two sell-side engagements we have published. TobinLeff found a six-fold spread in reply rate between agency sub-verticals such as performance marketing, PR and healthcare communications, which is also why digital marketing agency acquisitions treats the category as several markets rather than one. A generalist firm that scores a lead "marketing agency" without that split is working with a blunter instrument than the sector rewards.

How should a buyer choose between these marketing agency deal sourcing firms

1. 1. Ask whether the firm has run an agency mandate, not whether agencies are on its list. Two of six name the sector; a reference request separates a real track record from a buy box that happens to include it.
2. 2. Segment the category before writing a target list. Performance, PR, creative, healthcare communications and B2B agencies are different markets with different buyers, a point both our sell-side work and digital marketing agency acquisitions make from opposite sides of the table.
3. 3. Start with $5m to $50m agencies. At 2.8 open owners per 1,000 emails against 0.7 for larger ones, twenty conversations in the smaller band needs roughly a quarter of the volume. Our owner outreach calculator runs that math for a given target.
4. 4. Decide whether the mandate is buy-side or sell-side, a distinction covered in sell-side vs buy-side origination, before comparing pricing models across the list above.

Several of these providers also work outside this sector, and how the main deal sourcing companies compare covers them on fee model and process more broadly. For the firms that pitch specifically to agency and advisory buyers, generalist outbound agency vs deal origination specialist is a related comparison worth reading alongside this one.

Conclusion

Marketing agencies are a sector where the data argues for moving fast and segmenting early: owners reply more than most sectors we measure, smaller agency owners reply about four times more than larger ones, and only two of the six generalist firms we checked say they know the category at all. The other four will still take the retainer, but a buyer paying for sector expertise should know which two actually claim it. Our own corporate development and M&A advisor roundups cover the same generalist pool against other buyer types, if a marketing agency thesis is one option among several on your list.

If you would rather have this run for you, DealSource Systems does off-market deal sourcing for lower middle market private equity: owners reached directly before they run a process, for a flat $4,000 a month.
