Product Blueprint
FlowLens — a real-time payment health monitoring and anomaly intelligence layer that sits on top of Silverflow's API (and other cloud-native processors) to give mid-market merchants a single dashboard showing authorization rate degradation, issuer-level decline pattern spikes, and network routing inefficiencies, with AI-generated fix recommendations pushed as Slack/email alerts.
Why it matters
Silverflow nearing 1B annual transactions signals cloud-native processing is mainstream for mid-market, but the observability tooling hasn't caught up — Datadog doesn't speak payments, and enterprise solutions like Kount or Stripe Radar are fraud-focused, not performance-focused. A 1% auth rate lift on $50M GMV is $500K recovered annually, making ROI trivially obvious.
Target user
Payments or finance ops manager at a mid-market e-commerce or SaaS company (50–500 employees, $10M–$200M GMV) processing on Silverflow, Stripe, or Adyen who has no dedicated payments engineer and loses 1–3% authorization rates to fixable issues they only discover during monthly reviews.
Go-to-market
MVP is a read-only Silverflow API connector that ingests 30 days of transaction history and outputs a one-page 'Authorization Health Report' as a PDF — sell this as a $500 one-time audit to 10 Silverflow merchants sourced from LinkedIn outreach to payments ops managers at Shopify Plus stores; convert audits into $800/month recurring monitoring subscriptions with a Slack bot that fires alerts when hourly auth rates drop 2% below 7-day baseline.
