Storytelling Case Study Content Engine
Based on Marvin Sanginés's public method. Not affiliated with or endorsed by Marvin Sanginés.
When to use
Use this skill when a B2B founder, executive, or Content Strategist needs to turn lived experience and client outcomes into a credible LinkedIn transformation story. It also supports planning the weekly podcast-style conversation that supplies those stories, reviewing drafts, and placing case studies inside a broader content calendar.
The deliverable is a four-part post, accompanied by an internal evidence record, interview follow-ups, and a practical handoff. Adapt to the requested scope: an existing transcript needs extraction and editing; a planning request needs an interview brief; a revision request needs a stronger draft and an explanation of material changes. Do not pretend an interview occurred or expand a writing assignment into publishing, messaging prospects, or buying ads.
Sanginés reports that this format drives about 60% of notus inbound leads. That is a self-reported result for his business, not a forecast for the user. His separate revenue attribution claim refers to his personal LinkedIn profile. Preserve this distinction whenever discussing the method's performance. Read the provenance notes in references/sources.md before quoting results or explaining the attribution.
Procedure
-
Set the reader and commercial context. Identify the ideal customer, their recognizable problem, the founder's offer, and the intended next step. Use the system foundation in references/method.md. If context is absent, state a working assumption and ask only for information that changes the story selection.
-
Choose a supportable transformation. Find a client story with a concrete starting situation, meaningful intervention, and observable outcome. Check comparability to the intended reader rather than choosing the largest number. Apply the selection rules in references/method.md.
-
Prepare the weekly conversation. Build an agenda from recent work, audience questions, prior comments, and relevant creator posts. Draft questions around missing story evidence. Use references/method.md and the interview fields in templates/output-template.md.
