Founding Growth

Growth Intern (Summer 2026)

Description

_“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.”

Values

No matter what you know about Growth - every time member operates within these values:

1. The Wizard of Oz \- do something manually before automating it.

_Manually close one billboard in SF or edit a video yourself._

2. The Shipyard \- our unit of work at Lix. Everything has a “deliverable” - no theorizing.

_Someone who can write a landing page, set up a HubSpot flow, cut a video, AND think strategically about positioning - not someone who just writes briefs for agencies._

3. Hackathon mentality \- get a lot done in a little time, like a hackathon

_Build an entire Q3 marketing strategy in a single Saturday afternoon._

4. Disinfect with sunlight \- we know the first step to solving a problem is putting sunlight on the issue.

_Create a dashboard of our engagement and make goal-line of where to get to._

5. We love schlep \- We love the small, annoying problems.

_Edit a specific part of the video until it’s just-right._

6. Delta force - A unit of A players beats an army of B-players

_Be the best at your craft._

7. Beat the starting pistol \- Don’t wait for formality, completeness, or perfection to begin. This value is about the inputs, not the outputs

_We have a big launch video. Make the v1 in 2 hours._

8. Feedback is a gift \- We take feedback seriously - and no feedback is too harsh for us to learn something from.

_How do you learn from feedback?_
