As answered by people managing Subversive Leader and Cert Decoder.
Subversive Leader's answer
Dr. Latisha saw that executive coaching was transformative but priced at $300+ per hour, locking out emerging leaders who needed it most. She built an AI coach named Zmara grounded in her dissertation research to deliver that depth of coaching at an accessible price.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Subversive Leader's answer
React, TypeScript, Node.js, PostgreSQL, Google Gemini AI, Stripe.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Subversive Leader's answer
Early and mid-career professionals developing their leadership identity. Especially those from marginalized backgrounds navigating leadership in environments that were not built for their success.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Subversive Leader's answer
Most AI coaching tools use generic frameworks that treat leadership as tasks to optimize. Subversive Leader treats leadership as an identity to develop. Zmara remembers past conversations, tracks goals, and coaches through real challenges at $79-$149/month instead of enterprise-only pricing.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
Subversive Leader's answer
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Subversive Leader's answer
Built on a proprietary leadership framework from academic research, not generic coaching models. The AI coach Zmara engages in real conversations about identity, power dynamics, and authentic leadership. Includes structured assessments, goal tracking, and development milestones.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
