A warm intro is a referral from a mutual connection to a prospect — dramatically more effective than cold outreach. A warm intro converts at 5–10x the rate of cold because trust is transferred from the introducer. At early stage, systematically mining your investor network, advisor board, and existing customers for warm intros is often the most efficient growth lever before you've built brand awareness.
For example, asking an investor who knows the Head of Engineering at your target account to make a 2-line email intro will typically result in a meeting 40–60% of the time, versus 2–5% for cold email to the same person.
We help clients build systematic warm intro programs using their existing network — turning every customer and investor into an active referral source.
