The SG Team
A team, not a person.
Human leadership, backed by specialist systems SG built and runs on its own operation first — subject-matter depth across every facet of the work, organized around one focal point: the client.
Human leadership
Erik Herring, Managing Director
U.S. military veteran. Field-facing operations, business development, and operational diagnostics — from branch and jobsite execution to federal field programs. Every engagement is led, reviewed, and signed by the Managing Director; no output reaches a client without human verification.
The documented record is public: the field records and the standards ledger say more than a biography would.
The assessment stack — built, not staffed
These are AI analysis systems SG built and operates — instruments, not personnel. On client work they process signals and records on schedule; they make no judgments, author no deliverables, and never talk to your team. SG also turns AI critics loose on its own releases — that log is public on the standards page. Most firms this size staff up with subcontractors and do not tell you. SG built its own instruments and does.
Research & signal intelligence
Watches federal solicitations, filings, and market movement on a schedule — every finding tied to its source, never retyped from memory.
Risk & severity scoring
Classifies exposure and scores severity on a fixed, versioned rubric — the same grade for the same facts, every time.
Fit & gap analysis
Runs the 3-State Gap Model deterministically: Beginning State, Current State, Desired State, and the measured distance between them.
Data integrity & infrastructure
Keeps the records, watchdogs, and audit trails honest — including the release gates that have rejected SG's own work, on the record.
Founder service record
Where the discipline was forged.
Service and employment history, stated plainly — no seals, no logos, no borrowed letterhead. Employers and public agencies are stated as facts of service; commercial counterparties and client names appear only with written authority on file.
1989–1997
U.S. Marine Corps — HMX-1 Presidential Helicopter Squadron
Active duty 1989–95, active reserves 1995–97. Supported Marine One operations; Presidential Service Badge for qualifying presidential-support duty.
1996–2006
U.S. Customs Service — later U.S. Customs and Border Protection (DHS)
Ten years of federal inspection, compliance, and chain-of-custody discipline across Toronto and Tampa assignments, through the 2003 DHS reorganization.
2006–2009
Investigations and protective operations
Federal criminal defense case management, national director of field operations for a surveillance and investigations network, and executive protection work.
2009–2015
Program manager, U.S. federal counter-narcotics support programs
Day-to-day operations for a 60-plus-person program at roughly $16M a year — staffing, performance, budget control, and executive reporting.
2015–2017
DEA Global Training Team — lead instructor and course developer
Interdiction curriculum built and delivered across Kenya, Dubai, and Central Asia — doctrine turned into instruction teams could repeat.
2017–2019
International technical advisor
Contract advisory role, held alongside the YANMAR work from 2018 — directed in-field advisors across international operating environments: deployment, reporting, budget oversight, and threat assessment.
2018–2020
YANMAR America — technical training developer
Dealer-network certification programs: field procedures designed to be learned, inspected, and repeated.
2020–2024
Sunbelt Rentals — market manager, temporary power and HVAC rental
Authored the field procedures behind Sunbelt's early battery-energy-storage applications and introduced them on live jobsites. Part of the team that landed a Fortune-500 pharmaceutical manufacturer's manufacturing program — the account scaled to a dedicated onsite support branch.
2024–
Sustainable Gaps LLC — Managing Director
Founded November 2024 — the record above, systematized into one method. Project Management Professional (PMP) since 2012 — verifiable in the PMI registry. Since 2023, top-tier clients under NDA — through AlphaSights, and GLG since 2024 — have paid by the hour for the founder's operational read, most recently on data-center mission-critical power and HVAC.
Every line above has paper behind it — service records, program files, the PMI credential registry — filed the same way the engagement evidence is. Question any line on the first call and the relevant file gets pulled; the lines that end in confidentiality say so on their face.
The client is the focal point
Every specialist on this page — human or system — exists to expedite and implement the client's solution. The structure is organized around your engagement, not around billable roles.
Continuity is built in, not promised
The systems keep collecting, scoring, and recording regardless of anyone's calendar — and every engagement leaves client-owned records that run without SG. The key-person question is answered by architecture, not assurances.
Disclosed, because it has to be
Some of SG's specialists are AI systems, built by SG and run on SG's own operation before any client work. That is stated plainly because one of the firm's public refusals is 'nothing invented' — and a team page is the first place firms usually break that rule.
