Separate product pages or one on Twitter?

I'd like to know, what is the best way to handle social marketing & presence.

We have a main 'product', which is just the name of our 'brand' - if I can call it that: coolLabs. I

But we will have several products, currently we have 2.

Here, on Indie Hackers, we will create a product page for each, that's sure.

What about Twitter?

• Should have separate account for each product?
• Or you one base account (in the example for coolLabs) & use hashtags if I post something related to one of our application?

I think separate should be the way, but I'm not experienced in this territory.
