Cold DM to an investor (no prior relationship)
You've engaged with their content a few times. They follow you back. Now you have a soft warm signal.
Hi [first name] — appreciate you following back. Quick context: I'm building [company] for [specific audience]. [One traction proof point: $X MRR, N customers, Y growth rate over Z time]. Noticed you've invested in [specific portfolio company] — we've talked to them about [specific learning] and the patterns rhyme with what we're seeing. If you're seeing more [your category] this year, would love a 15-min call to share what we're learning.
Why this works
Names specific traction + names a specific portfolio company (proves you've done homework). The 'patterns rhyme' line creates relevance. 15-min ask is low-commitment.
