Valkyrie is a failed payment recovery service built specifically for Stripe subscription businesses. When a customer's payment fails, Stripe's built-in Smart Retries handle some of it automatically. But hard declines like expired cards, lost cards, wrong card numbers need the customer to actually update their payment method. That gap is where subscription revenue quietly disappears every month.

Valkyrie identifies every failed payment in your Stripe account, classifies each one, and sends a branded sequence of up to four recovery emails to your customers asking them to update their card. The sequence runs over 14 days and stops the moment a card is updated. You never pay for what Stripe already recovers on its own, Valkyrie only charges on the lift above Stripe's baseline.

The pricing model is simple: 25% of what Valkyrie actually recovers, after a 7-day hold to confirm each recovery stuck. No platform fee. No monthly minimum. No charge if nothing is recovered. Invoices go out monthly, covering all recoveries from the previous month.

Getting started takes 60 seconds. Connect your Stripe account via OAuth, and Valkyrie immediately shows you a breakdown of your last 90 days: total failed payments, what Stripe already recovered on its own, and what is genuinely recoverable with outreach. This analysis is completely free with no card required. You only pay if you choose to activate recovery and Valkyrie finds money.

Every recovery is fully traceable. The dashboard shows each failed payment, the email sequence sent, when the customer updated their card, and the exact fee charged. Nothing is bundled or hidden. Valkyrie never moves money, never changes Stripe account settings, and access can be revoked from the Stripe dashboard at any time.

Valkyrie is built for subscription businesses doing between $5,000 and $500,000 in monthly recurring revenue who want a transparent, low-risk way to recover revenue they are already losing.

Slicker features and specs

  • Automated Code Refactoring
    Slicker automates the process of moving and renaming Python code, handling import updates and references across your codebase, which saves developers significant time and reduces manual errors.
  • Simple Command-Line Interface
    Slicker provides a straightforward CLI that makes it easy to perform code moves and renames without needing a complex IDE setup or heavy tooling.
  • Python-Focused
    Being purpose-built for Python, Slicker understands Python-specific syntax, import styles, and module structures, making it more reliable for Python refactoring tasks than generic tools.
  • Open Source
    Slicker is an open-source tool, meaning developers can inspect the code, contribute improvements, and use it freely without licensing costs.
  • Handles Import Rewrites
    One of Slicker's strongest features is its ability to automatically find and update all import statements and references when moving or renaming modules, functions, or classes across a project.

Possible disadvantages of Slicker

  • Limited Scope of Refactoring
    Slicker focuses primarily on move and rename operations. It does not support broader refactoring patterns like extracting methods, inlining variables, or restructuring class hierarchies.
  • Python-Only
    Slicker only works with Python codebases, so teams working in multi-language environments will need additional tools for other languages.
  • Limited Community and Adoption
    Slicker has a relatively small user base compared to refactoring tools built into major IDEs like PyCharm or VS Code, which means fewer community resources, tutorials, and third-party support.
  • May Not Handle All Edge Cases
    Complex or unconventional import patterns, dynamic imports, or non-standard project structures may not be fully supported, potentially requiring manual cleanup after refactoring.
  • Minimal Documentation
    As a smaller open-source project, Slicker may have limited documentation and examples, making it harder for new users to understand advanced usage or troubleshoot issues.

Valkyrie features and specs

  • Stripe Connect Integration
    Connects to your Stripe account via OAuth in 60 seconds. Valkyrie can never move money, create charges, or change account settings.
  • Intelligent Payment Classification
    Every failed payment is classified into three categories: what Stripe already recovered on its own, what is genuinely recoverable with outreach, and what is unresolvable. You only pay for the recoverable category.
  • Branded Recovery Email Sequences
    Sends up to 4 branded emails to your customers over 14 days asking them to update their payment method. Emails use your company name and brand color. Sequence stops the moment a card is updated.
  • Transparent Recovery Attribution
    Every recovery is traced end to end โ€” failed payment, email sent, card updated, charge succeeded. You see the full trail on every dollar. Stripe baseline recoveries are shown separately and never billed.
  • Performance-Only Pricing
    No platform fee, no monthly minimum. Valkyrie charges 25% of recovered revenue only, after a 7-day hold confirms each recovery stuck. Invoiced monthly. Zero charge if nothing is recovered.
  • Free Pre-Activation Analysis
    Connect your Stripe account and see your real failed payment data โ€” total failed, what Stripe recovered, and what is genuinely recoverable โ€” completely free before committing to anything.
  • Monthly Billing Digest
    One invoice per month covering all recoveries from the previous month. Clear itemization showing each recovery, the amount, the date, and the fee charged.
  • Merchant Dashboard
    Full visibility into recovery activity, email sequence status, billing history, and ROI tracking. Includes a recovery rate trend chart and running total of revenue recovered versus fees paid.

Questions & Answers

As answered by people managing Slicker and Valkyrie.

How would you describe the primary audience of your product?

Valkyrie's answer:

Founders and operators running subscription businesses on Stripe with monthly recurring revenue between $5,000 and $500,000. Typically bootstrapped or early-stage, managing billing themselves without a dedicated finance team, and losing 5-8% of MRR to failed payments without knowing it.

What makes your product unique?

Valkyrie's answer:

Valkyrie only charges on the lift above what Stripe already recovers for free. Most recovery tools take credit for Stripe's own automatic retries. We show you exactly what Stripe did versus what we found, and only bill on the difference. Free analysis before you commit to anything.

Why should a person choose your product over its competitors?

Valkyrie's answer:

Most recovery tools charge a monthly platform fee regardless of results, and count Stripe's own automatic recoveries as their wins. Valkyrie charges nothing unless it recovers money above what Stripe already does for free. You can connect your Stripe account and see your exact recoverable amount before paying anything. No demo call, no sales process, no minimum commitment. 25% of what we find, nothing else.

What's the story behind your product?

Valkyrie's answer:

Valkyrie was built by Bruce O'Toole, a finance and operations professional who kept seeing the same problem: subscription businesses carefully managing their revenue while quietly losing 5-8% of MRR to failed payments nobody was chasing. Stripe recovers some automatically. The rest just disappears. Valkyrie was built to chase the rest, with full transparency on every dollar and a pricing model that only works if the merchant wins first.

Which are the primary technologies used for building your product?

Valkyrie's answer:

Next.js, Supabase (PostgreSQL), Stripe Connect, Resend, Vercel. Built and designed using Claude Code and v0 by Vercel.

Who are some of the biggest customers of your product?

Valkyrie's answer:

Valkyrie launched in 2026 and is currently onboarding its first merchants. Early users are subscription SaaS founders and membership businesses in the $5,000 to $100,000 MRR range.
