Preston Zeller, fractional growth leader for SaaS companies

Growth isn't a demand problem.
It's an ops problem — I fix that.

Fractional growth leadership for founder-led Seed to Series B companies. I've recovered $1.43M in annual churn, saved 540 hours through billing automation, and replaced six-figure vendor contracts with AI-native systems built in-house.

Preston Zeller, Chief Growth Officer specializing in revenue infrastructure

Hey, I'm Preston

I find revenue hiding in your existing operations and build the infrastructure to capture it. Churn recovery, billing automation, pricing optimization — the unsexy systems that drive the biggest gains.

I'm what happens when a documentary filmmaker becomes a Chief Growth Officer. Weird combo? Maybe. But it works — I've turned invisible churn into seven-figure recoveries, scaled organic traffic from near-zero to hundreds of thousands of monthly visitors, and replaced expensive vendor contracts with AI-native tools built over a weekend.

I ship systems, not slide decks.

The SaaS Playbook Is Being Rewritten

In early 2026, ~$300 billion in SaaS market value evaporated in a single week. Not from an earnings miss — from an AI product release. The assumption that broke was the durability of legacy SaaS growth.

Feature competition compresses margins. Workflow replacement redirects spend.

AI doesn't just build better features. It replaces the human workflows that legacy software was designed to support. When workflows move, value moves with them.

Customers don't rip out systems overnight. They consolidate, renegotiate, reduce usage.

Cash flow weakens before logos disappear. By the time churn shows up in your metrics, the workflow substitution already happened.

The market isn't shrinking — it's reallocating.

Value is moving from software licenses to outcomes. Companies aren't paying less for software. They're paying less for access and more for impact.

I've been building the post-SaaS playbook before it had a name.

Approach

Most growth problems aren't marketing problems. They're operational gaps masquerading as demand issues. I find the $500K sitting in your existing customer base, the 15 hours/week your team wastes on manual billing, the conversations happening about your market that you're missing entirely.

Why This Works

Diagnostic First

I don't start with solutions. I start by understanding what's actually broken — so I don't waste your time fixing the wrong problem.

Operator Mentality

I've watched too many strategy decks gather dust. I build the thing — whether that's a workflow, an agent, or a system — not just the plan for the thing.

P&L Matters

Every initiative ties to revenue, margin, or efficiency. If I can't connect it to your P&L, I won't recommend it.

Build vs. Buy Clarity

I've replaced six-figure SaaS contracts with AI-powered builds. But I also know when to buy. You won't get ideology — you'll get the right answer for where the market is heading.

Methodology Over Guesswork

Growth isn't about 'trying things and seeing what sticks.' It's about structured experimentation — clear hypotheses, defined success criteria, and knowing when to kill what isn't working.

Services

Fractional CGO/CRO

Embedded growth leadership for 3-6 month engagements. I diagnose what's broken, build what's missing, and leave your team equipped to run it without me. Most companies start here.

Starting at $10K/month

90-Day Revenue Sprints

One high-impact problem, fixed scope, measurable outcome. Churn recovery, billing automation, AI workflow migration, SEO infrastructure, or pricing optimization. You'll know the ROI before we start.

Fixed scope, typically $25-50K

Growth Diagnostics

Not sure where to start? This is a structured audit of your revenue systems, pricing, and operational bottlenecks — with a prioritized roadmap of what to fix first and why.

Starting at $5K

Pricing & Messaging Strategy

Most Series A-B companies are leaving 20-30% on the table through pricing alone. I quantify the gap and help you close it — often the highest-ROI project you can run.

Project-based, typically $10-15K

Who I Work With

Series A-B Companies

You've found product-market fit but revenue growth has stalled. Churn is eating into gains, billing is manual, and AI is compressing the economics you built on. I embed with your team, find the hidden revenue, and build the systems to capture it.

Bootstrapped & Profitable

You've built something real without venture capital, but you're hitting a ceiling. I bring the growth infrastructure playbook from VC-backed companies — churn systems, pricing optimization, AI-native workflows, SEO engines — without the bloated team or agency overhead.

Revenue systems, growth infrastructure, and ventures I've built

Churn Recovery System

Organic search was generating 15K monthly visitors for a company preparing to IPO. Built the technical SEO and content infrastructure that scaled it to 400K+ — with zero incremental ad spend.

What They Say

From the CEOs and executives who bet on a different kind of growth leader

BatchService needed to fundamentally rethink their approach to growth.

“His talent for turning a complex vision into a clear, actionable plan was incredible to watch and fundamentally changed how we approach growth. Preston is a natural leader who can provide strategic direction but also get in the trenches when required.”

Ivo Draginov

Co-Founder, President, BatchService

ZoomInfo's digital programs were underperforming relative to the company's ambitions.

“He grew our digital programs to unprecedented numbers—optimized user experience, increased traffic acquisition, improved conversion rates. With very little resources, he delivered on all three. Roughly 40% of all new business revenue came from digital programs.”

DeAnn Poe

VP of Marketing, ZoomInfo

Strategic finance was lacking and needed an internal partner.

“Preston has a rare ability to see both the big picture and the small details, adjusting on the fly—a crucial skill set for a rapidly growing SaaS company. He strategically drove results that directly impacted the company's trajectory.”

Leigh Anne White

VP of Finance, Propstream

ZoomInfo needed to level its content game to become a thought leader in a crowded space.

“Sometimes you work with a person that has it all going on, has it all together, SO much that interactions with them feel like a breath of fresh air every single time. In short, Preston is a pro.”

David Sill

Former Head of Sales, ZoomInfo

Story

The unconventional path from film school to Chief Growth Officer

2024-Present

Building What's Next

Launching my own products while advising growth-stage companies. Psalmlog (voice-to-text journaling with AI reflection) and ASOfuel (App Store Optimization intelligence) are live. Still doing fractional CGO work — but increasingly building the tools I wished existed.

2022-2024

Documentary & Growth Leadership

Released 'The Art of Grieving' — a documentary that reached 40+ countries and got coverage in Phoenix New Times, NBC, and NPR. Simultaneously served as Chief Growth Officer at BatchService, where I oversaw multiple business lines and and an exit from 2 companies to one of the largest national title companies.

2019-2021

Loss, Art, and a $2B Acquisition

My brother Colin died. I painted every day for a year to process it — while leading digital & growth marketing at A Cloud Guru leading up to their $2B acquisition by Pluralsight. The documentary I'd eventually make about that grief process reached 40+ countries. Sometimes the hardest seasons produce the most important work.

2016-2019

ZoomInfo: Hypergrowth to Pre-IPO

Grew organic traffic from 15K to 400K+ monthly visitors (2,653% increase) while managing two acquisitions, a complete rebrand, and IPO preparation. Roughly 40% of all new business revenue came from digital programs. ZoomInfo went public in 2020.

2000-2016

Creative Foundation & Digital Marketing Pioneer

Chapman film school and Hollywood (ICM Partners, E! Networks, DreamWorks) built the storytelling lens. Founding Zellerhaus Digital brought conversion optimization, SEO, and data-driven marketing across lifestyle, medical devices, finance, and real estate. The unusual path from filmmaker to marketer became the foundation for everything that followed.
