## About This Blog

Welcome to **Experimenting with Growth**, my corner of the internet where I document what it really takes to grow products.

I’m [**Rishikesh Ranjan**](https://www.linkedin.com/in/ranjan-rishikesh/)**, a growth hacker & GTM engineer**. On any given day, I’m juggling roles: part marketer, part data analyst, part automation engineer, and part product strategist. This blog is where I share the experiments, frameworks, and lessons from that messy mix.

## Why This Blog Exists

Most content on “growth hacking” is advice-heavy: do this, don’t do that. The truth? **Growth isn’t a formula. It’s experiments.**

Here, I don’t pretend to have a guidebook of answers. Instead, I:

- Share **real experiments** I’ve run (what worked and what didn’t).
- Break down **growth loops, funnels, and GTM plays** from SaaS & PLG companies.
- Explore how **AI & automation** are reshaping growth.
- Publish **interviews with founders and operators** who’ve done this at scale.

If you’re building or growing a product, you’ll find practical takeaways you can test in your own work.

## What You’ll Find Here

- **Case Studies & Breakdowns** → e.g. PostHog, Perplexity, Cursor AI, Lovable
- **Growth Loops & Frameworks** → word-of-mouth loops, viral loops, community loops
- **AI + Growth Experiments** → LangChain, Relay.app, PostHog MaxAI, n8n automations
- **Playbooks from the Field** → experiments I’ve run at [StreamAlive](https://streamalive.com/) and beyond
- **Founder Interviews** → lessons from SaaS leaders and GTM engineers turned founders

## Why Subscribe

- Get **new experiments** in your inbox before they hit LinkedIn/Twitter.
- Learn **practical frameworks** you can immediately apply.
- Access **behind-the-scenes stories** that don’t make it to public posts.
- Join a **community of builders, hackers, and GTM engineers** who think in loops, not just funnels.

I publish about **1–2 times a month**. No fluff, no recycled advice, just experiments, numbers, and lessons.
