Hi, I’m Rahi.

If we’re getting formal, I’m the founder of RetainUp.

You’re on this website, reading these carefully curated words, because you’re hungry to grow your business profitably.

Not to hear my life story.

So, I’ll keep it short.

In the summer of 2011, I started my own ecommerce business – IndiaRush.

Over the next decade or so, our team of 100+ strong and I grew IndiaRush to an annual $10M+ revenue ecommerce fashion brand.

So, when I say that I get the challenges of growing an ecommerce business – I mean it.

Over the years, one of the main challenges we faced was figuring out customer retention & repeat purchases.

Eventually, the company wound down due to the lack of customer retention and high acquisition costs.

Thus began the journey of building a solution for this.

Enter: RetainUp
I started RetainUp in 2020.

With a singular aim to help ecommerce founders increase repeat purchases without spending an extra dollar on ads.

Fast forward to today, and we’ve got 80+ clients around the planet and over $63 Million in reported client revenue.

And my mission is to help ecommerce brands grow profitably.

But that’s enough about me.

I want to know about you.

That begins with booking the Retention Strategy Session with us.

Be quick! Our spots fill up fast.

Our Mission - Profitable Growth

Most companies are happy that they have a high revenue – but that does not always mean a high profit.

Our entire mission at RetainUp is to help ecommerce brands grow profitably.

And how do we do that?

Let me break it down for you. It’s one word…

RETENTION

Who says you have to keep pouring money down the bottomless pit of Facebook and Google ads to grow your ecommerce business?

We help you leverage the gold mine you’re already sitting on.

The challenge isn’t making sales. The challenge is getting repeat customers.

So, what’s holding you back?

You’re already here – you know you’re ready to take the next step.
