About Eric Lessman
I’m Eric Lessman, and I lead marketing inside growing companies.
This site explains how I work and who that work is for. This page explains how I show up.
I work best inside complexity.
Not as a consultant delivering advice from the outside, and not as an executor chasing outputs, but as a leader embedded in the system where decisions are made.
That means listening before acting. Naming what others are circling but not saying. Setting priorities that hold under pressure. Staying present as conditions change.
People I work with often tell me the same thing:
Things feel calmer.
Decisions move again.
The noise drops.
That is not because I bring a clever framework.
It is because I bring leadership that stays.
Experience as pattern recognition
Over the past 15 years, I’ve worked across SaaS, e-commerce, healthcare, recruiting, and other growth-stage environments.
The details change, but the patterns repeat.
Marketing becomes reactive as organizations grow.
Founders become the default integrator.
Strategy fragments across teams.
Execution speeds up while alignment slows down.
I’ve been brought in at those moments to help organizations regain clarity and momentum without creating more chaos in the process.
Not by doing more.
By deciding better.
Experience highlights
- Fractional CMO for growth-stage companies
- Former co-founder of a strategy and UX firm
- Background in systems thinking, discovery, and product-led environments
- Advisor to founders navigating growth, change, and complexity
These experiences matter not as credentials, but because they sharpen judgment.
Why Thrum exists
Thrum exists because most marketing problems are not marketing problems. They are leadership problems.
They show up as unclear priorities, stalled decisions, misaligned teams, and a constant sense of reactivity.
Tools and tactics cannot fix that.
I created Thrum to formalize a way of working that embeds leadership where it’s needed, rather than selling advice from the sidelines.
They are leadership problems.
They show up as unclear priorities, stalled decisions, misaligned teams, and a constant sense of reactivity. Tools and tactics cannot fix that.
The name comes from rhythm.
When leadership is present and aligned, work moves with a steady pulse.
Decisions connect.
Teams regain confidence.
Progress compounds instead of resetting.
That is what I help organizations build.
Boundaries and principles
What I will and will not do.
I will not sell tactics without context.
I will not create decks that never get used.
I will not optimize for speed at the expense of clarity.
I will not disappear after planning is done.
I will embed where leadership is needed.
I will name tradeoffs honestly.
I will help teams align around what matters now.
I will stay present as conditions change.
These boundaries protect the work and the people involved.
If the way I think about leadership and clarity resonates, you can learn more about what working together looks like.
Curious whether this kind of leadership would help your company?
We can talk.
