Publishing in two weeksInsights · Three weekly columns
Three weekly columns. Three voices. One publication.
The Cardinal Source publishes three articles per week, each on a fixed day, in a distinct voice, for a different reader need. The Analyst Note is the vertical deep-dive. The Field Note is the vertical flyover. The Brief is the technology layer underneath. Together they form the buyer-side record of how mid-market operators should source technology in 2026.
The columns
The publishing rhythm.
Tuesday is the technology layer. Wednesday is the deep vertical. Thursday is the wider vertical view. Pick the one that fits how you want to read.
Tuesday
The Brief
The technology layer underneath. UCaaS, CCaaS, SD-WAN, security, AI, network — explained for operators making procurement decisions.
Wednesday
The Analyst Note
Vertical deep-dives. The cornerstone research piece — 6 to 12 weeks of work on one industry, then we move to the next.
Thursday
The Field Note
Vertical flyovers. A sharp observation about one industry — what we're seeing in current sourcing engagements that operators in that vertical should know about.
The Brief Tuesdays
The technology layer.
Each Brief takes one technology category — UCaaS, CCaaS, SD-WAN, security, AI, network — and explains it the way a CIO making a procurement decision needs to hear it. Named vendors. Real prices. Maturity by category. Recurring sub-series: The AI Layer.
Where AI actually fits in your tech stack: a layered map
AI is not a category to procure — it is a layer that attaches to whatever you already own. The seven stack layers, what AI does at each one, and the procurement sequence that makes ROI observable in 90 days.
8 min · Anchor piece · The AI Layer seriesWhat your UCaaS already ships with (and what you're paying extra for)
Zoom AI Companion, RingCentral RingSense, Webex AI Assistant, Dialpad Ai, 8x8 Engage. Most operators do not know what is already bundled in their existing license, and what is a real add-on. The eight-question bundled-vs-billed audit.
7 min · The AI Layer seriesThe Analyst Note Wednesdays
Vertical deep-dives.
Each Analyst Note is part of a 6 to 12 week deep-dive series on one industry. The cornerstone article identifies the structural constraints. Subsequent pieces in the series go deep on EHR integration, BAA structure, compliance load, or whatever the vertical-specific dispositive constraint is. Current series: Healthcare.
How mid-market healthcare operators should source technology contracts in 2026
The EHR boundary and the Business Associate Agreement disqualify vendors before price. The anchor of the Healthcare series, with a six-question pre-commercial gate you can paste into your RFP.
11 min · Anchor · Healthcare series piece 1 of 6EHR integration as the disqualifying constraint
Epic, Cerner, eClinicalWorks, athenahealth, Cornerstone. Why integration depth filters most vendor shortlists before commercial terms enter the conversation.
Publishing next Wednesday · Healthcare series piece 2 of 6The BAA that actually protects you: a vendor-side audit
What the Business Associate Agreement should contain. Sub-processor disclosures, breach notification windows, audit rights, indemnification structure.
Publishing in two weeks · Healthcare series piece 3 of 6The Field Note Thursdays
Vertical flyovers.
Each Field Note takes one specialty or sub-vertical and writes a short, sharp piece about what we are seeing in current sourcing engagements. One or two pieces per vertical, then we rotate. Built for distribution on LinkedIn and X.
Veterinary group tech stack: the three vendors multi-location practices underuse
HIPAA-aware call handling for vet hospitals, integration with Cornerstone or ezyVet without breaking referrals, and the multi-clinic network architecture that scales past 30 sites.
14 min · Published June 2026Dental DSO phone systems: why most get the multi-location routing wrong
Why the standard CCaaS deployment in a 20-location DSO leaves money on the table, what the right multi-location routing looks like, and the three vendors that price for dental specifically.
Publishing this ThursdayAuto dealership BDC tech: the CCaaS setup most dealers are missing
CDK and Reynolds shape the contact center decision more than the CCaaS feature list. What integration depth actually means for an auto dealership group, and the four-rooftop-and-up sourcing pattern we see most often.
