Idea validation if there is an established competitor

Hi,

I have been thinking of building a team-based SMS (text messages) system for sales, support, and marketing. I originally came across it when a friend looking for this kind of service.

Problem statement:
SMS is an effective medium in terms of open rates and engagement, but employees prefer not to share their personal mobile numbers, and team engagement is impossible.

Solution:
Using teamSMS a company can create multiple inboxes (mobile numbers) and assign them to departments or individuals to chat with customers and drop an incoming message.

Progress:
I have a WIP product landing page.

Competitor:
In my research, I have found a competitor in this space that has a really feature-rich product. They look like they are successful, and can add a lot of value to users.

They have a ton of features like templating, automation, CRM integrations, slack, salesforce, Zapier (allowing 1000s of integrations) and it would take a long time to have feature parity.

What do you think my options are?
A) I can ship a really simple and cheaper version of this product, and see if I get any traction, they charge quite a lot
B) I can try and niche it out, for example, integration with a CRM they don't support, or catering it to a specific industry, like hotels or plumbers...
C) Dropping it and finding something else to build.

Anyone have some insights to share on this?
