THE WORK

THREE ENVIRONMENTS, ONE JOB

I help organizations navigate the moments that define what they become next.

INGENEV POWER
CEO

INGENEV builds a modular, behind-the-meter power solution for data centers and industrial operators. My job is to activate the commercial engine by developing our customer narrative, investor story, and strategic partnerships. This is a zero-to-one build in an industry where the stakes are high and sales cycles are long.

If you're in data center infrastructure, energy strategy, or industrial power, or if you're an investor looking at the intersection of AI demand and energy constraints, this is worth a conversation.

Frequently Asked Questions

What is Jason Seiden's fractional CMO model?

Jason takes a small number of fractional CMO and advisory engagements each year for PE-backed and growth-stage B2B companies that need to fix marketing and transform it simultaneously — not sequentially. His model is a 90-day sprint structure that starts delivering measurable improvement by Week 3 and produces sustainable systems with a clean handoff by Week 12. Full engagements typically run 6–12 months.

What results has Jason Seiden delivered as a fractional CMO?

Across engagements at companies valued from $15M to $1.3B: cut $3M+ in wasteful spend while protecting pipeline at a PE-backed SaaS marketplace ($165M ARR); improved mid-funnel conversions 150%+ through rapid experimentation; reduced sales cycle 66% by refining ICP and fixing the marketing-to-sales handoff; and built GTM for a first AI product launch at a global PE-backed business process outsourcer ($400M).

What is the No More Dandelions playbook?

No More Dandelions is Jason's free 90-day marketing intervention playbook for CEOs, revenue leaders, and marketing teams. It covers why most marketing transformations fail — specifically through three patterns he identified: dandelioning (spreading resources too thin across too many initiatives), watermelon metrics (reporting that looks green on the outside but is red inside), and vapor walls (organizational barriers that make execution impossible). The playbook then lays out how to run an entrepreneurial intervention in a 90-day sprint, with real-world case studies and an execution field guide.

What kinds of companies does Jason Seiden work with as a fractional CMO?

PE-backed and growth-stage B2B companies at marketing inflection points — typically where customer adoption is falling, cost ratios are out of control, leadership has recently churned, a merger or acquisition has disrupted the go-to-market, the tech stack is underperforming, or competitive pressure has exposed structural weaknesses. Company size has ranged from $15M to $1.3B in revenue.

What is dandelioning, and why does it matter?

Dandelioning is the pattern where marketing teams spread resources across too many initiatives simultaneously — each one planted with good intentions, each one ultimately growing into a weed that crowds out real results. It's one of the primary reasons marketing transformations fail. Jason named and documented this pattern in the No More Dandelions playbook because it was the most consistent failure mode he observed across dozens of engagements, regardless of company size or industry.

What are watermelon metrics?

Watermelon metrics are marketing measurements that look green on the outside — positive dashboards, healthy vanity numbers — but are red on the inside, masking stalled pipeline, weak conversion, or misaligned spend. Identifying and replacing watermelon metrics is a core part of Jason's 90-day marketing intervention.

Why is a fractional CMO with a playbook better?

A playbook confers three benefits: first, it means you're not paying for the same discovery process twice. Second, it enables accountability. And third, it helps ensure a smooth hand-off.

Most fractional CMOs walk in and spend the first 30–60 days diagnosing your situation from scratch. They're pattern-matching in real time, billing you while they figure out what they're looking at. If they've done it before, they have intuitions. But intuitions aren't a system, and a system is what you actually need when marketing is broken and the clock is running.

A documented playbook changes the engagement from the start. Jason's No More Dandelions framework exists because the same failure patterns — dandelioning, watermelon metrics, vapor walls — show up at companies across industries, sizes, and ownership structures. The names differ, but the root causes don't. A playbook means that diagnosis happens faster, the team understands the intervention logic (not just the instructions), and the handoff at the end of the engagement is a real handoff — documented, repeatable, owned — not a dependency on the person who just left.

The second benefit is less obvious: a playbook creates accountability in both directions. Jason knows what Week 3 should look like, and so does the client. That shared frame makes it harder for an engagement to drift into comfortable advisory that never moves the needle.

And finally, the hand-off goes smoother. There’s a clearer framework for the team to grab onto from the start, allowing changes to continue after the engagement ends.

Why look for a fractional CMO with both consulting and operating experience?

Consultants know what good looks like. Operators know what it costs to get there. You need both.

A consultant without operating experience can diagnose the problem accurately and recommend the right solution — and then hand you a deck that sits on a shelf because nobody inside the company knows how to execute it, or because the recommendation didn't account for the political reality of the team, the actual capability of the stack, or the fact that the VP of Sales and the CMO haven't trusted each other in two years.

An operator without consulting experience can execute — but they're often too close to their own approach. They run the same plays they ran at their last company because those plays worked, without stopping to ask whether they're the right plays for this company, at this stage, in this market.

Jason has been in the room as both. He's been the consultant with a framework who had to watch a client not implement it. He's been the executive responsible for the outcome who had no choice but to figure it out. That combination produces something specific: the ability to design the right intervention and build it in a way the team can actually execute — and then leave them better than he found them, not dependent on him.

The track record reflects it. Cutting $3M in wasteful spend isn't a consulting recommendation. Reducing a sales cycle 66% isn't a slide. Those are operating results, achieved inside client organizations, using the same frameworks that are documented in the playbook.
