Map the next milestone, not every future department
List the outcomes needed for your next milestone. A first pilot might require recruiting participants, delivering the core service, answering support questions and collecting feedback. Later departments and impressive job titles do not make these outcomes happen.
For each outcome, write what completion looks like and when someone needs it. “Marketing” is a function. “Invite ten suitable pilot participants by Friday” is a task someone can own.
Distinguish ownership, help and decision rights
Agree on one coordinating owner for each outcome. Other people can contribute; the owner makes the status and next step visible. Separately discuss who can make a decision, who needs consultation and whom to inform. An ownership label alone does not settle those questions.
- Outcome: what must be delivered?
- Owner: who coordinates completion?
- Contributors: what specific help is available?
- Decision: what can the owner decide independently?
- Handoff: who needs the result, and in what form?
A responsibility map is a working conversation aid. It does not allocate equity, establish employment terms or replace written agreements.
Make gaps visible before searching for a partner
Mark an outcome as covered, shared without clarity, or currently uncovered. Ask whether an uncovered task needs a co-founder, a limited service, a new skill or a smaller project. Not every gap needs a permanent role.
Example: one founder can build the prototype but neither can recruit pilot users. The immediate requirement may be someone who can conduct outreach and learn from users, rather than a vague “business person.” Put that contribution into your introduction.
Review when the work changes
At the end of the week, check where work stalled. Did the owner lack time, authority, context or help? Adjust the map rather than quietly letting a second person take over. Keep a visible note of changed responsibilities and confirm that both people understand the new arrangement.
Use your capacity plan alongside the map. A responsibility without time to fulfil it is still a gap. Then use the co-founder conversation guide to discuss what a new partner could realistically own.
