B2B SaaS is the slowest growth category on this site, and the one most distorted by survivor bias on Twitter. The founders who hit $10K MRR fast usually didn't get there from a viral launch — they got there from one painful pilot customer, then another, then a referral. The playbooks below show how indie founders broke into B2B without enterprise sales experience: cold email that didn't suck, niche communities where buyers actually hang out, free internal tools spun out into products, integrations into platforms with hungry user bases. If you're building B2B and your inbox is empty, look at the early phase moves — most of these companies were quiet for 6-12 months before anything compounded. Don't model the spike. Model the loop that produced it.
