Executive Assistant to the Founder (Operations, Process and AI)

About us

Growthub is a creative agency that makes high-performing paid ad creatives for brands that want to scale. We specialize in "stealth creatives": podcast clips, street interviews, skits and authority-led educational ads that feel like native social content rather than typical UGC.

We run the full creative process in-house, from customer research and creative strategy to filmmaking, direct response editing and data-led iteration. Brands we have worked with include Shapermint, Obvi and MamaBird, and we have scaled clients such as an AI SaaS app past $1M/month in ad spend.

As we grow, the Founder needs a right hand who can turn how things get done today into clear, repeatable systems.

About the role

This is not a traditional inbox-and-calendar EA role. You will work side by side with the Founder every day, watching how they work, spotting what repeats, and turning it into documented processes, automations and AI-powered workflows.

You will join an existing part-time assistant who will continue to support a few hours a day. You will be the full-time owner of the Founder's operations, available during ET business hours.

Key responsibilities

Shadow and systemize

• Sit in on the Founder's daily work (calls, reviews, planning, client and team communication) and map what they actually do.
• Identify recurring tasks and decisions, then write them up as clear SOPs, checklists and templates.
• Hand off documented processes to the team and make sure they are followed.

Automate and apply AI

• Build automations that remove manual steps across our tools (project management, docs, Slack, email, CRM, forms).
• Design and test AI workflows (Claude, ChatGPT and similar) for research, briefs, summaries, reporting and admin.
• Keep a living library of prompts, automations and workflows, and improve them over time.

Project and executive support

• Track the Founder's priorities, projects and deadlines, and follow up with the team so nothing slips.
• Prepare agendas, take notes and turn meetings into action items with owners and dates.
• Manage the Founder's calendar, inbox triage and day-to-day admin.
• Coordinate with the part-time assistant on handovers and shared tasks.

Requirements

• Project management background: 2+ years running projects, timelines and multiple stakeholders.
• Agency experience is a must: you have worked in or with a creative, marketing or advertising agency and understand client deadlines, revisions and production workflows.
• Excellent written and spoken English, clear, confident and professional.
• Available full time during US Eastern Time (ET) business hours.
• Hands-on with AI tools and comfortable experimenting with new ones.
• Strong process mindset: you naturally document, simplify and improve how work gets done.
• Highly organized, proactive and comfortable working directly with a fast-moving founder.
• Reliable internet connection and a quiet workspace.

Nice to have

• Experience with automation platforms such as Zapier, Make or n8n.
• Familiarity with Notion, Slack, Google Workspace and similar tools.
• Exposure to video, ad or content production workflows.
• Previous EA or chief-of-staff experience supporting a founder or executive.
