their capital wall is paper-thin — runs on commodity cloud + free tiers.

the blunt take.
“Recurly's entire homepage is a "book a demo" funnel — there's no pricing page, no self-serve signup, and no path for a $500/mo SaaS founder to just start. That's not an oversight; it's a deliberate enterprise posture that abandons the long tail.”
The core mechanics — plan management, dunning, failed-payment retries, proration, and a subscriber portal — are well-understood problems with open-source implementations. The moat is 15 years of payment processor relationships and enterprise integrations, not the billing logic itself. A focused indie tool targeting early-stage SaaS founders who want Recurly's features without Recurly's sales process has a real wedge.
