1. Introduction of Signup Gate

• The speaker is launching their fifth SAS product, Signup Gate, designed to protect against unwanted signups.
• Signup Gate is a single-purpose micro-SAS.
• It uses AI under the hood for its operations, but it's primarily an API-first tool rather than a UI-heavy application.
• It's positioned as a cost-saving internal tool that has been used by the speaker's team for years.

2. Functionality and Use Cases

• Signup Gate's primary function is to check email domains or IP addresses against a database to assess signup risk.
• The tool informs users if a signup is too risky, enabling them to block it before any damage occurs.
• Recommended applications include protecting SAS platforms, newsletters, e-commerce stores, and any online service requiring signups.
• Expected benefits include a reduction in chargebacks, disputes, and exploitative usage.

3. Origin Story: Addressing Dispute Issues

• In 2023, the speaker faced high dispute rates on Stripe with their first two SAS products.
• Configuring Stripe's Radar rules proved insufficient.
• The speaker manually compiled a list of disposable email domains and blocked signups from them.
• This resulted in a reduction in dispute rates and excess product usage.
• This led to the birth of what would become Signup Gate, initially a manual list.

4. Core Database and Blocking Methods

• Signup Gate checks against a database containing:
  • Tens of thousands of internet service providers (ISPs).
  • Hundreds of thousands of disposable email domains.
  • Thousands of VPNs, proxies, and Tor nodes.
• The database is continuously updated based on new disputes and abuse patterns.
• The speaker utilized open-source libraries of proxies, VPNs, and Tor nodes.
• Currently, Signup Gate has prevented over 90 high and medium-risk signups this month across the speaker's products.

5. Analytics and Reporting

• Signup Gate provides basic analytics to monitor the results of the risk assessments and blocked signups.

6. Custom Blacklists and Whitelists

• Users can create custom blacklists to block specific emails, IP addresses, or domains.
• Users can create whitelists to allow specific emails or IPs, overriding Signup Gate's risk assessment.

7. Community-Driven Updates

• Users can submit emails, IPs, or domains to the public Signup Gate list.
• If multiple users submit the same item, Signup Gate will flag it as medium, then high risk.
• This protects against fraud, abuse, and general problematic user behavior.

8. Pricing and Founder Stack Integration

• Signup Gate is available starting at $9 per month.
• It's also part of Founder Stack, offering lifetime access as part of the bundle.
• Existing Founder Stack customers automatically have lifetime access.

9. Notable Quotes

• "Put this in front of your SAS, your newsletter, your e-commerce store, or any online service that requires a sign up, and you will see a drop in chargebacks, disputes, and other unwanted exploitative usage of your product."
• "If you think it belongs on Signup Gate, you can submit it."

10. Technical Terms

• SAS: Software as a Service.
• API: Application Programming Interface.
• Stripe Radar: Stripe's built-in fraud prevention system.
• Disposable Email Domain: Temporary email addresses often used for spam or abuse.
• Proxy/VPN/Tor Node: Methods to mask IP addresses and locations.
• Chargeback: A reversal of a credit card payment initiated by the cardholder.
• ISP: Internet Service Provider.

11. Synthesis/Conclusion

Signup Gate is presented as a practical, API-first SAS product designed to proactively prevent fraudulent signups and protect online services from abuse. It leverages a comprehensive database of risky IPs, domains, and user-submitted data, offering a balance between automated risk assessment and user customization through blacklists and whitelists. The product’s integration with Founder Stack and community-driven update mechanism emphasize its value proposition for bootstrapped founders and indie hackers seeking to minimize financial losses and operational disruptions.
