WHO WE ARE

We've built an AI-native internal platform that powers every aspect of our Amazon brand management business. AI isn't a feature — it's the backbone.

- LLMs classify and respond to inbound communications

- AI generates pre-call intelligence briefs from raw enrichment data

- A RAG system feeds context into every generation pipeline

- An AI checkpoint system audits all generated content against quality gates

The platform is already live and scaling fast:
• 17+ background services
• 130+ frontend pages
• 214 backend services
• 184 database tables
• Dozens of autonomous AI pipelines
OUR CORE VALUES
Be A Moral Human

Serve a higher purpose. Everything we build and every decision we make is grounded in doing the right thing.
Improve 1% Daily

Strive for 1% better every day. Consistent, compounding improvement is how we build world-class systems and teams.
Extreme Ownership

Own your actions. No excuses, no hand-offs as a crutch. If it's in your world, it's your responsibility.
Solve Problems, Don't Create Them

Every challenge has a solution. Don't slow down the team by creating new problems — come with answers, not blockers.
Make an Impact

Focus on meaningful results. We measure success by the difference we make, not the hours we log.
Fail Fast & Fail Forward

Don't be afraid to fail. Take that failure, learn from it, and move forward stronger. Every failure is a lesson.
