Cloud Storage Egress Cost Router
A drop-in API proxy that sits in front of standard object storage. It automatically caches frequently accessed files on unmetered bare-metal networks, dramatically reducing expensive outbound data fees from major clouds.
Why this matters
You are an engineering leader managing a fast-growing application with terabytes of media assets stored on major cloud infrastructure. As your user base scales, your outbound data transfer bills are ballooning uncontrollably, severely dwarfing your actual storage costs. You feel financially trapped because migrating your entire data infrastructure away from these established ecosystems is too risky and resource-intensive, yet paying an eighty-fold markup on bandwidth feels like sheer extortion. Existing content delivery networks offer some relief but still incur hefty origin fetch costs and complex cache invalidation issues. You need a seamless, drop-in proxy layer that automatically caches and serves your heavy data buckets from alternative zero-egress networks, dramatically cutting your monthly bandwidth invoice without requiring any fundamental changes to your core system architecture.
- · Built for Mid-market SaaS and media applications spending over $1,000/month on cloud egress fees..
- · Most likely monetization: SaaS subscription based on a percentage of money saved (e.g., taking 20% of the egress cost reduction)..

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Major cloud providers drastically lower their bandwidth pricing to compete with new zero-egress alternatives, destroying your margin.
- 2Companies are unwilling to update their application DNS and endpoints to route through an unproven startup's infrastructure.
- 3Handling massive concurrent data streams efficiently requires complex infrastructure that is difficult to stabilize in an MVP.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Multiple developers in the discussion highlighted the massive discrepancy between raw bandwidth costs and the prices charged by major cloud providers. Several participants pointed out that transferring tens of terabytes costs thousands of dollars on established clouds, while budget hosting providers offer the same bandwidth essentially for free. The consensus indicates a strong frustration with high outbound data fees and a deep desire to circumvent these artificial markups without having to manually manage bare-metal servers.
