Founding Growth Marketer

Founding Growth Marketer - Endurance Sports - AI fluentZWIM | Lisbon, Portugal | Full-time | In-office + flex |Swimming is still the last major endurance sport without a proper connected training platform.
ZWIM is building Connected Swim Training, a new category at the intersection of endurance sport, smart training hardware, gaming, and performance feedback.
ZWIM is a
hardware + software business
, with a
direct-to-consumer model and subscription revenue
layered on top.
We help triathletes and swimmers train more consistently, improve faster, and make swim training more engaging.
ZWIM is backed by €1.4M in seed funding.
More than 20,000 athletes used our first swim training product, and thousands of people are already on the ZWIM waitlist.
Now we need our first full-time marketing hire to turn that into preorder revenue.
You'll Build The DTC Growth Engine From The Ground UpThis is a founding operator role for someone who can lead by doing.
The mission is simple:
Turn product proof into preorder revenue.This is not just demand generation.
It is demand conversion.
We need someone who has helped take a consumer product from early interest to paying customers before.
That could be a preorder campaign, waitlist conversion, founder drop, early access launch, community-led launch, crowdfunding-style campaign, or DTC growth sprint.
You will work across Shopify, Klaviyo, content, email, community, athlete activation, customer conversations, conversion, automation, and weekly reporting.
Content is a daily part of the job.
You should be comfortable picking up the camera, filming behind-the-scenes product work, capturing athletes and customers using the product, writing copy, creating simple graphics, publishing across channels, and learning from the numbers.
You do not need to be world-class at every part of this.
But you do need to be the kind of person who is not scared to do all of it.
What You'll OwnPreorders and conversionMove people from "this looks interesting" to "I'm in."
Own launch messaging, offer communication, Shopify landing page input, Klaviyo email sequences, customer replies, objection tracking, preorder updates, and weekly improvements to the buying journey.
Content and distributionCreate and publish content daily.
This includes UGC, athlete reactions, product demos, game footage, behind-the-scenes product work, customer stories, simple graphics, launch updates, and short-form video.
This is not just briefing content.
You will plan the angle, pick up the camera, capture the moment, edit the output, write the post, publish it, and learn from the response.
Email, community, and customer momentumOwn the list and help turn early customers, athletes, and interested followers into something more valuable than an audience.
Welcome flows, nurture, launch sequences, preorder updates, customer education, reactivation, segmentation, and post-purchase communication.
Athlete and ambassador activationHelp us get more value from athletes, ambassadors, early testers, and customers.
Capture reactions, help athletes tell better stories, turn feedback into useful content, give people reasons to share, and create moments that bring more people into the launch.
Marketing systems and automationThis is not about using AI for a few prompts.
We are looking for someone who's buildt workflows and internal tools that make marketing faster: content repurposing workflows, customer objection banks, ambassador trackers, email templates, launch dashboards, Notion/Airtable systems, Make/Zapier/n8n automations, or lightweight AI workflows.
Engineering experience is not required.
Builder mindset is required.
MetricsNo vanity numbers.
Revenue, preorders, conversion, activation, retention, and customer growth matter.

The launch content rhythm is live
The email list is warmer, better segmented, and moving toward preorder action
