“The company story is the company strategy - Ben Horowitz”
As a Growth Intern, you’re going to help spread the gospel about Selix, our Agent helping companies run their outbound sales end to end.
You’ll be jumping into all areas of growth:
Product Marketing - create assets and decks for post-sales and more
Social Media - building the narrative around what we’re building and how we’re different (we are the AI SDR killer)
Events - putting up events for the team and others to come
Website - sprucing up pages on our website with the help of our designer to tell our story
SEO / AEO - writing relevant articles on new insights we have on the space
Top of funnel - making marketing assets that can be useful for teams
Videos - making quick-cut videos we can use to post online for
The bottom line: take care of top of funnel activities.
Think "Scrappy startup PMM" than "big company content marketer.”
