👋 Hey, Linas here! Welcome to another special issue of my daily newsletter. Each day, I focus on 3 stories that are making a difference in the financial technology space. Coupled with things worth watching & the most important money movements, it’s the only newsletter you need for all things when Finance meets Tech. If you’re reading this for the first time, it’s a brilliant opportunity to join a community of 360k+ FinTech leaders:

AI has crossed a quiet but decisive line. It’s now an incredible capability layer, and yet most companies are still treating it like an experiment.

That’s why today I’m sharing The AI Leader Playbook.

It’s a practical, first-principles guide for engineering and product leaders who want results - not demos, not vibes, not theory. It breaks down exactly how the most effective teams are becoming AI-native: from coding agents and context-rich workflows to AI-native product design, security, governance, and ROI measurement.

It’s written for operators. By operators.

The kind of playbook you’d expect from teams like Ramp (h/t Rahul Sengottuvelu for sharing the brief version of this), where AI is treated as infrastructure, engineering leverage, and a competitive moat, not a side experiment.

Inside, you’ll find:

  • Concrete implementation patterns you can ship this quarter

  • Clear guidance on what to do in your first 90 days

  • The real tradeoffs leaders face around models, tools, security, and speed

  • A ruthless focus on productivity, iteration, and business impact

  • Plus, you will get instant & full access to 120+ AI Use Cases From Leading Startups & Internet Companies, The Ultimate AI Agent Stack, and 100s of other resources to learn, build, and scale.

If you’re leading engineers, building AI-powered products, or trying to make AI adoption actually pay off - this is the manual most teams wish they had 6 months ago.

Unlock it, and start compounding. Let’s dive in:
