Operator-led RevOps & GTM systems · Deliverability-grade diagnostics

Built for companies that outgrew their structure.

You grew on relationships, referrals, and people who knew what they were doing. Then the people move on, the tools multiply, and none of it is written down. System Integrity Ops builds the operating structure underneath the growth, so it keeps scaling when the original team, the founder, or the tribal knowledge is no longer in the room. Visible pipeline, documented operations, and email infrastructure your revenue can rely on.

Start with a diagnostic See the work
// What breaks first when you scale

Growth outran the structure. The business grew on relationships and instinct. None of it is documented, so none of it scales, and it all depends on people who might leave.

Tools multiplied. Architecture didn't. New CRM, new sending tools, new pipeline, all inheriting the same broken patterns at higher volume. Nobody audits how they connect.

When something breaks, teams scramble. A stalled pipeline, a blocked domain, a rep who left with the whole system in their head. Recovery is expensive. Prevention isn't.

// Entry points

Where to
start.

Operator-delivered. No tool reports. No AI-generated summaries. A direct read on your system, and a plan your team can run. Start with a diagnostic, then go as deep as the operation needs.

From $4,500

The CEO asks a question the pipeline can't answer. The operation lives in one person's head, and that person might leave. The tool stack has accumulated cost nobody has audited. This is the build that makes the pipeline visible, documents the operation, and removes the spend without losing capability.

Scope a build
// What gets built
  • Pipeline reporting leadership can actually run on, across every motion in one view
  • Documented operating model that removes single-person dependencies
  • CRM structure, deal stages, ownership rules, and handoff protocol
  • Vendor and cost rationalization: spend removed without losing capability
  • Enforcement and standards that survive team turnover
  • Opens into a fractional engagement when you want it run, not just built

Email Deliverability
Audit

From $950
Scoped to your setup · USD

Outbound, onboarding, retention, billing, transactional. The mail your revenue runs on can fail silently, and by the time you see it in the numbers, you have already lost the quarter. This is the independent read on what is stable, what is at risk, and where your single points of failure are, before a reputation event takes them down. Scope runs from a fast signal check to a full system teardown, sized to your setup.

// Deliverables
  • Operator review of your full sending surface, not just cold outbound
  • System Integrity Score (0 to 100) calibrated against real failure patterns
  • Authentication and reputation snapshot with meaning, not just data
  • Risks ranked by urgency: what breaks first if you don't act
  • Risk-diversification plan: removing single points of failure across domains and providers
  • Stabilization actions you can start this week, plus a written brief for your team
  • Full teardown scope adds staged 30/60/90-day remediation and enforcement rules

Every diagnostic stands alone, or opens into fractional and retainer work when you want the system built and run, not just mapped.

// Beyond the diagnostic

When you need it built, not just mapped.

Every diagnostic can open into hands-on work: building the pipeline reporting, documenting the operation, rationalizing the tool stack, or rebuilding the email infrastructure. Fractional engagements are scoped after a diagnostic, so you're never buying a retainer blind.

Evaluating an acquisition?

Your deal team is the smartest in the room, and rigorous about everything except one thing: email. Most assume email infrastructure is stable. It rarely is. The target's revenue runs on email you cannot see in the deck, customer notifications, billing, onboarding, lifecycle, and almost nobody audits it pre or post-integration. That is exactly where revenue leaks after close, and it becomes your problem on day one. Email Infrastructure Due Diligence gives your deal team a priced, documented picture of what you are inheriting before the wire clears.

// Situation

Outbound revenue ran across 6 brands, but the operation lived in people's heads and the tool stack had accumulated cost nobody had audited. Growth was real; the structure underneath wasn't documented.

// Result
Live pipeline reporting across all 6 pipelines in one view. Ramp halved, campaign launch cut 4→2 weeks, ~$250K in vendor spend removed with capability intact.
// What we built
  • Pipeline reporting layer across 6 brands in a single leadership view
  • Documented operating model that removed single-person dependencies
  • Vendor rationalization: ~$250K removed without losing capability
  • AI-assisted lead cleanup that cut team ramp from 5 weeks to 3

// Situation

A merger that had to deliver. Two organizations, overlapping systems and accounts, and a synergy plan the deal depended on. Integration meant reconciling operations, retaining the accounts that mattered, and hitting targets while the business kept running.

// Result
Grew the company from $350M to roughly $700M as the number one EdTech specialty reseller in its category. Beat synergy targets by about $60M, with top accounts retained through the transition.
// Contribution
  • Key cross-functional contributor across 10 workstreams and 545 tracked activities
  • Operational reconciliation that protected capability while systems and teams combined
  • Account retention through the transition, keeping the revenue the deal was built on
  • Executive-facing materials supporting the integration and investor narrative
  • The pressure that shaped the operating model: integration under a live P&L, not theory

// Situation

No outbound infrastructure in place. Leadership needed a complete sending system designed, built, and documented before go-to-market, with a team that could run it without the operator in the room. Timing was fixed: the pre-IPO window.

// Result
3% reply rate at scale. Positive reply rate landed 20% above target inside the pre-IPO window. Zero block events. Team took over a documented, running system with automated deal creation in Pipedrive.
// What we built
  • 1,000 mailboxes across ~300 domains, chosen for 30–40% cost savings and automated DNS provisioning
  • Brand-new and prewarmed mailboxes sequenced into the warmup calendar without reputation risk
  • Clay enrichment and AI personalization integrated into the sequence workflow
  • Deliverability monitoring across the full domain fleet: SPF, DKIM, DMARC drift caught at scale
  • Positive-reply routing and deal-creation automation built directly into Pipedrive
  • Written enforcement model: send limits, escalation triggers, rep onboarding checklist

volume · zero incidents

// Situation

Multi-brand operation sending 1M emails/month with declining reply rates and no explanation. The sending was happening. The results weren't. Root cause turned out to be the sending platform itself, not the domains or the copy.

// Result
Reply rate doubled. Positive reply rate doubled. Same volume, same copy, same data. The infrastructure was the constraint. Migration completed without a single delivery incident.
// What we found + fixed
  • Diagnosed the sending platform as the primary failure point at this volume
  • Ran controlled cross-platform testing before committing to migration
  • Migrated the full sending operation once test results validated the difference
  • Rebuilt authentication (SPF/DKIM/DMARC) across all sending domains
  • Post-migration monitoring cadence in place from day one to catch drift early

M&A Revenue-Operation Due Diligence

liability register + exec brief
See engagement
// Situation

An M&A firm needed the target's revenue operation assessed before close. Outbound was a core revenue driver, but reputation, authentication health, and operational continuity are invisible in standard due diligence. Inherited problems become the buyer's problems on day one.

// Result
Buyer entered close with a priced, documented picture of what they were inheriting. Remediation costs and timeline were quantified. Infrastructure risk became a negotiation line item, not a post-close surprise.
// What we surfaced
  • Sender reputation already degraded on key domains: remediation cost and timeline quantified
  • Authentication misconfigurations creating compliance exposure
  • Institutional knowledge concentrated in one person not staying post-close, undocumented
  • Pipeline leakage already occurring, mapped to estimated revenue impact
  • Domain ownership history with overlap risk the buyer would inherit

// How we operate

Operating
Principles.

These aren't values. They're how we work, and how we expect clients to work.

Learn first,
then build
We never come into a business already knowing it. We learn the operation, the numbers, and the people first, then build.
System integrity
over hacks
Sustained performance comes from coherent system design, not short-term tactics or isolated optimizations.
Separation
before scale
Domains, identities, and workflows must be isolated by purpose before volume is introduced.
Prevention
over recovery
Failures are expensive to reverse. Systems should be designed to avoid degradation in advance.
Standards
over opinions
Scalable operations require defined standards and enforcement, not individual preference or debate.
// The operator behind System Integrity Ops

Built from
the inside out.

I don't come from marketing or email service providers. I come from operations. Fifteen years building and scaling revenue infrastructure inside SaaS, EdTech, and consulting. Reporting to CEOs and Presidents, learning the operation and the numbers first, then building.

I've scaled an RFP function from $5M to $30M. I've been a key contributor to a post-merger integration that beat synergy targets by ~$60M. I've run RevOps across 6 brands doing $100M+ a year. Pipeline, reporting, cost control, and the outbound engine underneath it.

Email is where I learned the discipline hardest. When email is the product, a broken sending system stops revenue, so I learned deliverability under real load, scaling outbound from 200K to 2M+ emails/month and building enforcement that survived team turnover.

System Integrity Ops exists because I kept seeing the same pattern: teams hire for growth, then scramble to build structure after something breaks. Prevention is cheaper. Structure is what scales.
