The funnel

A round needs coverage before it needs optimism.

The calculator works backwards from money needed to the active investor count required at each stage.

Coverage is weighted

A diligence conversation is worth more than a new contact because it is closer to a check.

Conversion changes everything

Warm network and cold outbound produce very different top-of-funnel needs.

Gaps are operational

The useful output is not a percentage. It is where to add investors this week.

Methodology

How the funnel is sized

The model estimates commits needed from check size, adds overage, then walks conversion rates backward through the funnel.

# core componentscommits_needed = ceil(target / avg_check x 1.3)diligence_needed = commits_needed / commit_ratepartner_needed = diligence_needed / diligence_ratecontacted_needed = replies_needed / reply_ratecoverage = weighted_have / weighted_need

The rates are benchmarks, not predictions.

Late-stage rows carry more weight because they are closer to dollars closed.

Failure modes

Coverage mistakes

Counting names, not active investors

A spreadsheet row is not coverage unless there is a live path or conversation.

Ignoring replacement rate

Passes and ghosts drain the funnel; new top-of-funnel has to replace them.

Overvaluing early replies

Replies are signal, not commitments. They still need to convert.

FAQ

Questions founders ask

How many investors should I contact?

It depends on check sizes and conversion. For a typical seed round, it is usually dozens of active conversations, not a handful.

Why can coverage be below 100% with investors in the pipeline?

Coverage is weighted by stage. Early contacts count for much less than partner meetings, diligence, or committed checks.

What conversion rates does it use?

Benchmarks adjust by how warm the process is. A warm, well-introduced round converts several times better than cold outbound.
