Fractional COO

Fractional COO & RevOps Operator for Seed–Series B SaaS | The operational backbone that makes founders scalable | Onboarding, renewals & RevOps clean-up

St. Louis, United States

About

I’m the operational backbone for Seed–Series B SaaS founders.

I parachute into 10–60 person startups and turn cross-functional friction between Sales, CS, Product, and Finance into an operating system everyone actually follows.

I don’t throw playbooks at your problems. I sit with your team, map the real prospect → client → renewal journey, and build human-first, AI-powered systems that stick long after I’m gone.

What that looks like IRL:

Onboarding cut from 18 days → 6, while keeping NRR at 100% during leadership gaps in both Sales and CS.

$30,000+ in missed ARR uncovered by fixing invoicing, collections, and internal handoffs.

Outstanding balances reduced by 90% after migrating 140+ clients to a streamlined Stripe-backed billing system.

Investor-ready data rooms assembled in days, not weeks, for active and upcoming raises.

Who I work best with:

B2B SaaS (sometimes fintech / recurring pro services)

Seed → Series B

10–60 people, no full-time COO, founder still in the weeds

Symptoms: onboarding slipping, renewals wobbly, messy handoffs, tools not talking to each other, fire drills as “the culture”

How I plug in:

Fractional COO / Ops Backbone – Embedded with your leadership team to own cross-functional ops, GTM rhythm, and clarity.

RevOps & Client Journey Sprints – 30- to 60-day projects to clean up your CRM, onboarding, renewals, and reporting so everyone finally sees the same truth.

Founder & Ops Advisory – Monthly calls + async support when you need a strategic operator, not a full-time hire.

If you’re a founder thinking, “We just signed new customers and CS isn’t ready,” or “Every team is busy but we’re not moving,” we should talk.
