About Us
Our Story
45+ years of engineering experience meets AI-powered building. One founder, multiple sustainable SaaS bets.
Bill Eisenhauer
Founder & Engineer
I've spent over four decades building software. I was one of the first engineers at a startup that grew into a $2B company. I've written code that processed billions of dollars in transactions. I've managed teams, architected systems, and debugged more production incidents than I can count.
Now, at 61, I'm doing something different. I'm building a portfolio of AI-powered SaaS products through Plenty of SaaS. Not because I have to—because I want to. The tools available today are unlike anything I've seen in my career.
The Journey
45 Years of Building
First Lines of Code
Typed BASIC games into an Apple II+. The spark that started everything.
Enterprise Systems
COBOL and mainframe development at EDS. Learning to build at scale.
Startup Life
Employee engineer #1 at a GPS tracking company. Built systems from scratch.
Silicon Valley Scale
7 years at a fashion-tech startup that went public. Learning to build practically and operate at scale.
AI Awakening
AI coding tools changed everything. Started seeing a path to building solo again.
Plenty of SaaS
Launched a portfolio of AI-powered SaaS bets. Building in public, sharing everything.
The Philosophy
Why Juggle Multiple SaaSes?
"Like a skilled juggler, we keep multiple SaaSes in the air—each one receiving the focus it needs at exactly the right moment."
Long-term Thinking
We build for decades, not quarters. Sustainable revenue over vanity metrics.
Innovation with Purpose
Technology that solves real problems for real people.
Building in Public
Transparency creates accountability. Real numbers, real lessons.
AI-Augmented Building
AI doesn't replace experience—it amplifies it. Learning to direct, not just code.
