How to share a startup signal with a co-investor
Share the signal in three layers: one sentence on what changed, one line on why it matters now, and one proof link. Keep it calm, specific, and easy to verify.
Most weak signal-sharing dies because it asks the other person to trust your excitement instead of the evidence.
Quick answer. Share the signal in three layers: what changed, why it matters now, and where to verify it.
What to send. Keep it short. Name the company, describe the change in plain language, explain why it looks early enough to matter, and include one proof link. Do not send a wall of screenshots if one clear proof path does the job.
Why this works. A co-investor does not need your full workflow first. He needs a clean reason to pay attention. Clarity beats intensity.
What to avoid. Do not oversell certainty. Do not dump five links with no guidance. Do not force the other person to reverse-engineer why you think the signal matters.
Quote-ready takeaway

Frequently asked questions
What is the minimum useful signal share?
One sentence on what changed, one sentence on why it matters now, and one proof link. Anything less is vague; anything much more often becomes noise.
Should I send the methodology every time?
Not always. Use the sample watchlist or the most relevant answer/comparison page first. Send methodology when the other person wants to inspect the logic itself.
Should I share a signal if I am still unsure?
Yes, but frame it honestly as an early read worth checking, not as a finished verdict.
