Comparison
DealSource Systems vs Deal Flow Advisory.
DealSource Systems wrote this page and DealSource Systems is one of the firms on it. That belongs in the first line, not in a footnote. Deal Flow Advisory publishes something most firms in this category will not: a target number of qualified seller introductions per quarter. That deserves credit and it deserves scrutiny, and this page does both. Claims were read off getdealflow.ai on 22 September 2026.
Who each one is for
Deal Flow Advisory runs two sides. For buyers it targets private equity firms and family offices, with a stated focus on a buy box around $5M to $10M of EBITDA. It also works with business owners directly, which makes it a two-sided operation rather than a pure vendor to acquirers.
DealSource Systems works for one side of the table at a time: the fund, advisor or bank paying for the mandate. We never represent the owner.
What Deal Flow Advisory actually does
The promise is delivered introductions: "We connect qualified business owners with serious buyers through direct, off-market conversations", and the headline is "Proprietary Deal Flow, Delivered." The published targets are between 30 and 45 qualified seller introductions per 90 days, against a buy box focused on businesses in the $5M to $10M EBITDA range, billed monthly against defined outputs.
The process is three steps in their words. First, "We proactively source and screen business owners in your target size range, industry focus, and geography. Every owner is personally contacted, qualified against your buy box criteria, and confirmed as genuinely interested in exploring a conversation." Second, each introduction arrives with "a structured deal brief: financial ranges, owner motivation and timeline, customer concentration, key risks, call notes, and our next-step recommendation". Third, "You advance the opportunities that fit your thesis."
They also publish a conversion claim, roughly 12% efficiency against roughly 1% for the traditional route. No method, sample size or period is given for either figure on the page, which is worth knowing before it is used in a comparison.
What we do
DealSource Systems runs origination as a standing function for private equity funds, M&A advisors, boutique investment banks and search funds. AI maps the market against your thesis, scores readiness signals on each company and drafts the approach. Then operators with deal experience review every message before an owner sees it and handle the replies, including the ones that need a real answer about structure or timing.
Pricing is on the site rather than behind a call: from $4,000 a month for a single thesis, $8,000 and above for a dedicated multi-thesis mandate, no success fee, 90-day minimum term. The engagement we publish in full is Merritt Healthcare Advisors, a healthcare investment bank: 14 qualified founder conversations in the first three weeks, 133 inside 90 days. We are part of Danish Lead Co.

Where Deal Flow Advisory is stronger than us
They put a number on the output. Between 30 and 45 qualified seller introductions per 90 days is a commitment most firms here avoid making, including us. We publish what our campaigns have produced, not a target for yours.
Every introduction comes with a brief. Financial ranges, owner motivation and timeline, customer concentration, key risks and call notes, handed over as a package. That is a genuinely useful deliverable and it is more structured than handing you a reply thread.
Billing tied to defined outputs. Monthly billing against stated outputs is easier to hold a vendor to than a retainer for effort.
Owner-side reach. Because they also work with owners directly, they have a pool we do not have.
Where we are stronger
Our numbers are auditable and theirs are not yet. We publish the dataset behind our claims: 1.7 million outreach emails, the median campaign producing three positive replies in its first 60 days, and about one in seven producing none. Their roughly 12% against roughly 1% comparison has no method, sample or period attached on the page. Ask them for it before you weigh it.
One side of the table. Working for buyers and owners at once creates a question about whose interest the introduction serves. We only ever work for the party paying for the mandate, which is a cleaner position when an owner asks who we represent.
Published pricing. Monthly billing against defined outputs is a model, not a price. Ours is on the site: from $4,000 a month, $8,000 and above for a dedicated multi-thesis mandate.
Sell-side mandates too. Their buyer product is aimed at PE firms and family offices. We also originate sell-side mandates for advisors and banks.
When to choose Deal Flow Advisory over us
Choose them if you are a fund or family office buying in the $5M to $10M EBITDA range and you want a stated number of introductions per quarter with a written brief on each one, and you are comfortable that the same firm also works with owners.
When to choose us over Deal Flow Advisory
Choose us if you want the evidence behind the numbers before you buy, if you want a firm that works only for your side of the table, if your mandate sits outside their buy box or on the sell side, or if you want origination as a standing function on your thesis rather than a delivered quota of introductions.
How we checked this
Read on 22 September 2026: getdealflow.ai for the positioning, the published output targets, the buy box focus, the billing description, the three-step process and the deal brief contents. Their conversion comparison is published without a stated method, and this page says so rather than repeating it as fact. Our own figures come from our published engagement, our stated pricing and our published benchmarks.
Common questions
How many introductions does Deal Flow Advisory promise?
Their site states a target of between 30 and 45 qualified seller introductions per 90 days, focused on a buy box around $5M to $10M of EBITDA, billed monthly against defined outputs. We do not promise a quota, and we publish what past campaigns actually produced instead.
Is their 12% conversion claim reliable?
It may well be, but the page publishes no method, sample size or period behind the roughly 12% figure or the roughly 1% it is compared against. Ask them for the working before you use it to choose. Ours is published in full so you can check it.
Do they work for buyers or for sellers?
Both. The site has a path for buyers and a path for business owners. That gives them reach we do not have, and it also means the introduction is coming from a firm with a relationship on both sides. We only work for the party paying for the mandate.
What is the biggest difference between the two firms?
What is being sold. They sell a delivered quantity of introductions inside a fixed buy box. We sell a standing origination function built around your thesis, with the measured method published so you can audit it before you buy.
