“Every single cent needs to equal a purchase or an add to cart.” That is how Matt Swulinski, who has led growth at Superhuman, Wispr Flow, and now Victor, thinks about SaaS marketing. His core argument is that the e-commerce playbook—hundreds of UGC creatives per month, aggressive paid spend, and obsessive conversion tracking—is the right playbook for SaaS. In this conversation, he walks through exactly how to set up that engine, from the first dollar of ad spend to building a team that can scale it.

The E-Com Playbook for SaaS: Paid as Validation

Swulinski’s philosophy flips the conventional SaaS wisdom that paid ads are a “dangerous drug” to avoid. He argues that paid is actually the fastest way to validate whether you have product-led growth (PLG). “Paid is the easiest way to validate that you have PLG, that you have a product that can scale,” he says. While organic content and brand-building take time, paid lets you test messaging, creative, funnels, and positioning within a week.

For an early-stage company, he recommends starting with the “core three” of any acquisition engine: Meta, Google, and lifecycle (email, SMS, push). Most founders should ignore TikTok, Reddit, and other channels until they have mastered these three. The budget depends on unit economics, but for a company that has raised $3–5 million, a $100,000 test budget is a reasonable starting point.

What you'll learn

  • 1 (04:39) **How PLG Changes in a World of AI Agents** - Matt explains that PLG still matters but must be optimized for how agents research and select tools, not just humans.
  • 2 (05:48) **The E-Com Playbook is the Right Playbook for SaaS** - Matt argues that SaaS should adopt the e-commerce approach: every cent must drive a purchase, with hundreds of UGC creatives and multiple channels.
  • 3 (07:51) **Why You Should Start Paid Ads Immediately** - Paid ads are the fastest way to validate product-led growth, test messaging, and refine funnels—far quicker than organic content or brand building.
  • 4 (08:44) **How Much to Spend and Where to Start as an Early-Stage Founder** - Start with Meta and Google only; avoid spreading too thin across TikTok, Reddit, etc.
  • 5 (10:32) **The Critical First Step: Proper Analytics & Conversion Tracking** - Before spending a single cent, ensure your analytics and conversion tracking are set up correctly—90% of companies skip this and then claim paid doesn't work.
  • 6 (13:44) **What Metrics to Optimize For in the Early Days** - Focus solely on acquisition cost (e.g., cost per download or trial start) and let the product team handle retention.
  • 7 (14:57) **What CAC-to-LTV Ratios Are Healthy at Different Stages** - If you've raised a lot, 1:1 is acceptable to grab market share; below that is burning money. Aim for 3:1 as you scale.
