Domino No. 1
A positioning and ICP brief for Driftmark, a fatigue management app built for shift workers
What Lina built.
Lina chose the Driftmark mission, a sleep-grounded fatigue management app serving shift workers sitting between two hospital pilots and an untested freight market. Her brief was to pick one PMM asset, make the case for it, and deliver it at portfolio quality in a week.
She chose positioning. Not a pitch deck, not a case study, not a homepage. Positioning. Her argument: every downstream marketing artifact derives from a shared answer to who the product is for, what it competes with, and why anyone should care. Build that first and everything else gets easier. Skip it and every artifact you ship pulls in a different direction.
The output was a unified Positioning and ICP Brief deployed as a single interactive web page, with the full case study reasoning and the finished deliverable living side by side. No toggling between documents. No context lost in translation. The reasoning and the result in one place.
"Picked positioning and ICP as the first-domino asset and made the case for why. Case study and asset on the same page so the reviewer does not navigate between artifacts."
Lina Debese, submission notesWhat the mentors saw.
What stood out was not just the quality of the final deliverable. It was the quality of the thinking behind the choices.
The problem diagnosis was specific. The market analysis identified a real beachhead, a real buyer, and a real reason why hospitals and freight required different sales motions. The anti-persona section mapped exactly who Driftmark should not pursue and why. The 30/60/90-day activation plan turned the strategy into a sequence of decisions the founding team could actually act on.
What also stood out was the format decision itself. Deploying the case study and the deliverable as a single web page was not a workaround. It was a deliberate design choice that made the submission easier to evaluate and significantly easier to present as a portfolio piece.
The STAR breakdown.
Driftmark is a sleep-grounded fatigue management app with a working product, two hospital pilots, and 40 users with strong retention. The team is two engineers and a sleep researcher. There is no marketing function, no shared positioning, and no consistent story across any public surface. The App Store description reads like a clinical abstract. Instagram has 61 followers. The symptoms look like a volume problem. The real problem is upstream.
Identify the single PMM asset that would make every other downstream marketing decision easier. Evaluate the full candidate list, make the case for the chosen asset, and deliver it at portfolio quality within the week.
Lina diagnosed the real problem as a foundation issue, not a volume issue. She evaluated eight candidate assets against five filters (upstreamness, gap fit, forced clarity, reusability, buildability) and chose positioning. From there she ran a full market analysis, identified mid-sized regional freight carriers as the beachhead over hospitals, defined the buyer profile, mapped the competitive landscape, and built a unified Positioning and ICP Brief. She deployed the case study and the deliverable together as a single interactive web page so nothing was lost in translation between documents.
A complete, portfolio-ready Positioning and ICP Brief for Driftmark: defined beachhead (mid-sized regional truckload carriers, 200 to 1,000 trucks), named buyer (Director of Safety / VP of Risk), competitive frame, two proven value pillars, and a 30/60/90-day activation plan. Scored at the top across all three independent mentor evaluations. Winner of Best Overall, 1st Place at PMM Jam 2026 Beta.
In their own words.
"As someone with a legal and insurance background, I thought the target ICP was unique and persuasive. Do you have experience in healthcare or insurance? You hit the mark here."
"The greenfield versus displacement section is gold. The beachhead section is gold. This briefing has more of a business plan feel, but is very much steeped in the goal of the assignment."
"This would make an excellent portfolio piece for a PMM, PM, or entrepreneurial role."
"I really like this format and the progression of your thought process."
See it for yourself.
Lina deployed both the case study and the finished deliverable as a single interactive web page. The full reasoning, the competitive analysis, the ICP, the 30/60/90-day plan, and the positioning brief are all there.
What Jammers were working with.
The Driftmark mission gave participants a fictional early-stage company: a sleep-grounded fatigue management app with a working product, two hospital pilot deployments, and zero formal marketing infrastructure. Jammers were challenged to diagnose the real PMM problem, choose the single highest-leverage asset to build first, make the case for that choice, and deliver it at portfolio quality. No prescribed deliverable, no single right answer. Just a brief and a week to figure it out.
