Asking Price Reasoning

Price ≈ SDE $868k × 3.35x (≈2.9x current ARR / 1.8x TTM revenue). TTM adjusted EBITDA margin was ~53%, with founder involvement under 2 hrs/week and subscription-led revenue supporting solid cash-flow quality. The multiple is within profitable SMB SaaS norms, but below premium growth comps, reflecting ~5% growth, MRR below peak after growth paused, and elevated 15.2% average logo churn—leaving upside through retention and reactivation.
