Enterprise & Federal
Enterprise services,
delivered through Varcoe.
Two brands, one practice. The enterprise catalog is mirrored here on Witness for visibility. The B2B sales motion runs through varcoe.ai. Same legal entity (Blueberry Security Global, Inc.), same Quinn, same delivery team.
Same firm. Same legal entity. Same Quinn.
Also available through varcoe.ai for B2B buyers.
Both brands are operated by Blueberry Security Global, Inc., a Delaware C-corporation. Quinnlan Varcoe (Founder and CEO) sets the methodology, oversees Alex Riffenburgh and the practitioner team that executes the work, and reviews every case before findings leave the practice under either brand. The split is by audience and brand voice, not by capability.
Witness (you are here)
The parent brand for the practice. Court-admissible methodology, senior practitioner on every engagement, NDA-protected consultations. Right front door for consumer, attorney, family- office, and most enterprise buyers who want to talk to Quinn directly.
Varcoe (B2B sister brand)
The B2B front door for the same practice. Procurement workflows, vendor onboarding, MSA paper, RFP responses. Useful when your buying process expects a B2B website and a B2B sales motion for the enterprise practice.
Visit varcoe.ai/The full enterprise catalog
Every enterprise service Quinn and the senior bench deliver, grouped by function. Each page covers what the engagement actually does, who it is for, what we deliver, and how an engagement begins. The same content runs under varcoe.ai for B2B buyers.
