Startup Growth Channels YC Founders Recommend

We ask YC founders one question: "What's working right now for growth?" Here's what they actually say—not what Medium articles say.

#1: Founder-Led Outbound (Every.Single.One)

YC founders still do their own outbound. Not forever—but at the beginning. Personal emails to their network, warm introductions, and targeted outreach.

#2: Referral Programs

• Dropbox: Referrals drove 35% of early growth
• Notion: Every customer gets an ask
• Loom: Built viral loops into product

#3: Community-First

• Craft a community around your users
• Slack groups, Discord, forums
• Customers become advocates

#4: Product-Led Growth

• Frictionless onboarding
• Built-in share features
• Value before asking for anything

#5: SEO & Content

• Answer questions your users ask
• Long-term compounding
• High-LTV channels once established

#6: Events (Specifically)

• Small, targeted meetups
• Demo days
• Industry conferences (not large ones)

The Pattern

Every growth channel YC founders share one thing: they're all focused on one-to-one. Not mass marketing. Personal, relationship-driven growth.
