Buy-Side Deal Sourcing · Retained Origination
Sentinel runs the off-market acquisition pipeline behind acquisitive platforms: off-market dental practice sourcing for DSOs, proprietary deal flow for PE-backed platforms, and add-on pipelines for MSOs, home services and staffing consolidators. Owners and operators approached by name, qualified against your buy box, before any broker sees the deal.

Auctions vs. Proprietary Flow
By the time a target reaches a broker, the seller's fee is priced in and every acquirer in the market sees the same deal. The platforms that grow fastest own the top of their own acquisition pipeline — proprietary conversations with owners and operators who weren't for sale yesterday. That pipeline is what we build and run for you.
A year of retainer is one point on one deal — and one deal returns it several times over.
What The Retainer Runs
Sentinel sources for retained buy-side partners only — we never present ourselves as the buyer, and we never take the sell side. On a retained mandate the cadence runs 3–5 qualified calls a week, 1–3 LOIs a month, and 4–10 closings a year — per platform, feeding a continuous add-on acquisition pipeline rather than a one-off search.
Off-market dental practice sourcing for DSOs, medical group sourcing for MSOs, operator sourcing for home services and staffing platforms — one owner universe built and approached by name per buy box. No broker listings.
Every submission is an owner or operator who confirmed the criteria and said yes to a meeting — size, revenue, transition posture verified on the call before it reaches you.
Proprietary deal flow for PE-backed platforms, built against your fund's specific buy box and reported weekly — approved by you, by name, before any introduction.
20+ qualified calls in the first 90 days — written into the agreement and reported weekly. Our floor is higher than most firms' ceiling.
Case File · Confidential
Names redacted by policy — the numbers are not.
We ran retained origination behind a PE-backed DSO platform, sourcing add-on after add-on until the platform stood at more than four times its starting footprint.
On the strength of that record, the fund itself engaged Sentinel directly — to launch an entirely new DSO in a new geography. We sourced the target that became its founding acquisition. The platform is live and acquiring today.

Where The Retainer Runs
The off-market method is the same in every vertical — the owner universe, the buy box and the cadence are built around your platform.
Off-market dental practice sourcing for DSOs — GP and specialty owners approached by name, qualified against your buy box.
Proprietary deal flow for PE-backed platforms — add-on origination behind a portfolio company, or the founding acquisition for a new roll-up.
The same off-market method applied to medical groups for platforms building an MSO.
An add-on acquisition pipeline of home services operators sourced off-market for consolidating platforms.
Off-market origination for staffing and services roll-ups building density through add-on acquisitions.
The engine is sector-agnostic; the depth points wherever your buy box does. On the board within the week — criteria locked, owners approached by name.
