If you're reading this, you're probably wondering what PPL Spark is, why it exists, and whether it's worth your time. This short course — six lessons, ~30 minutes total — is the fastest way to find out.
What this lab actually is
PPL Spark is both a product company and a practice. The product: AI tools that work on real conversations — live calls, recorded meetings, actual team dynamics — rather than simulating conversations for role-play. The practice: a weekly loop where the team analyzes its own calls through developmental psychology to sharpen methodology.
The two reinforce each other. Building AI that helps other people's conversations go better requires being very honest about how our own conversations go. The lab is where that honesty happens.
Who you are in this course
This course is written for three kinds of reader:
- Investors and partners trying to understand what we're building and whether it has legs.
- HR leaders and coaches evaluating whether RAIner fits their org or practice.
- Collaborators and new team members who need the full picture before going deeper.
Pick the frame that fits you. The course is the same either way.
How to use this course
Each lesson is short (4–8 minutes) and ends with a reflection prompt — one question worth sitting with for a minute. Your answers are saved only in your own browser. Nothing is sent anywhere.
You can skip forward if you want, but the lessons build on each other — starting at the beginning gives you the cleanest picture.
The route
- Welcome (you are here)
- Why conversations, why now — the founding bet
- RAIner — one dialogue, one trajectory — the product
- The developmental lens — what we build on, what we're different from
- Where we go to market — two scenarios, one product
- The Lab practice — how we work, and how to engage with us
Before you start
One commitment: treat the reflection prompts as real. They're not graded, they're not collected, but they are the difference between reading about adult development and actually doing five minutes of it. The course costs you ~30 minutes either way. Ten of those minutes spent reflecting will be worth more than the other twenty.
When you're ready, continue to Lesson 2.
