## 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 to 2 times a month**. No fluff, no recycled advice, just experiments, numbers, and lessons.

## FAQ: about Experimenting with Growth

#### What is Experimenting with Growth about?

Documenting what it actually takes to grow products, written by Rishikesh Ranjan, a growth hacker and GTM engineer whose work spans marketing, data analysis, automation engineering and product strategy. The premise is that growth is not a formula, it is experiments, so the blog publishes the experiments themselves rather than a guidebook of answers.

#### What will I find on this blog?

Four kinds of thing. Case studies and breakdowns of companies such as PostHog, Perplexity, Cursor AI and Lovable. Growth loops and frameworks, covering word-of-mouth loops, viral loops and community loops. AI and growth experiments using tools including LangChain, Relay.app, PostHog Max AI and n8n. And interviews with founders and operators.

#### How is this different from other growth hacking content?

Most growth hacking content is advice-heavy: do this, do not do that. This one shows real experiments that were actually run, including the ones that did not work, alongside the numbers behind them. The stated aim is not to tell you what works but to show how growth hackers think and test, which is what makes the failures as useful to publish as the wins.

#### How often does it publish, and why subscribe?

About one to two times a month, with no filler and no recycled advice. Subscribing gets new experiments by email before they appear on LinkedIn or Twitter, plus the frameworks in a form you can apply directly and behind-the-scenes detail that does not make it into the public posts.
