Executive Summary

Involuntary churn from payment failures is a persistent leak for any SaaS business that bills monthly or annually; across the industry we estimate roughly $6.0B annually is recoverable — about 3% of an estimated ~$200B global SaaS ARR — and it disproportionately hits mid-market and enterprise subscription vendors with high card-on-file volumes. Product teams and finance leaders bear the day-to-day pain: lost MRR, noisy dunning processes, and engineering cycles spent on brittle gateway integrations instead of core features. You could build a platform that automates payment-failure recovery end-to-end: real-time decline classification, cohort-informed retry orchestration, account-updater and network-based remediation, plus omnichannel customer nudges (email/SMS/in-app) and an analytics layer that ties recovered payments back to LTV impact. The technical product would lean on gateway webhooks and tokenized payment methods to avoid PCI scope, use ML to predict optimal retry timing per cohort, and provide pre-built integrations for 8–10 popular gateways and billing systems to reduce implementation friction. This is a compelling time to enter: subscription proliferation increases the number of billing events to optimize and payments APIs have matured enough to support automated remediation, while ML models now deliver actionable predictions that were impractical three years ago. Competition is medium and incumbents are either horizontal payment processors or narrow dunning tools, so the main challenges will be building clean, secure integrations at scale, demonstrating consistent lift (even a 20–40% recovery of the $6.0B pool is a meaningful ROI), and pricing accessibly for SMBs while meeting enterprise SLAs. To stand out, focus on measurable revenue impact and low-friction adoption: ship a SOC2-compliant connector catalogue, a simple policy engine for finance teams, and ML models that are explainable to reduce false positives and customer frustration. Be candid about trade-offs — integration complexity, regional compliance, and the need for ongoing model retraining — and prioritize a few verticals where payment behavior is predictable so you can iterate on outcome-driven case studies before broadening horizontally.

Market Opportunity

Fix SaaS billing leaks — automate payment-failure recovery to stop MRR bleed targets a $6.0B = 3% of ~$200B global SaaS ARR (estimated) recoverable annually from involuntary churn total addressable market with medium saturation and a year-over-year growth rate of 15-25% — driven by rising SaaS spend, more subscriptions, and attention to unit economics.

Key trends driving demand: Subscription proliferation -- more vendors mean more recurring billing events and more failure surface area to fix; Payments API maturity -- gateways expose richer webhooks and account-update services that allow real-time remediation; AI for payments -- ML models can now predict declines and identify optimal retry timing/channels at cohort scale; Customer experience expectation -- personalized, low-friction recovery beats blunt churn campaigns and preserves LTV.

Key competitors include Churn Buster, Stripe Billing (native dunning & smart retries), Chargebee, Recurly.
