Job description

Reactiv is rewriting the rules of mobile commerce. Our AI‑powered platform lets Shopify merchants spin up pixel‑perfect, revenue‑driving mobile apps in days—not months. With ReactivClips we went one step further, erasing the download wall so shoppers jump straight from an ad click to a fully branded app experience in seconds. We just closed our seed round, are scaling toward SeriesA, and need a whip‑smart EA to keep our leadership trio laser‑focused on the mission.

Our Values

• Think big, never compromise
• Lead by example
• Trust the team
• Solve the right problems at the right time
• Be transparent, honest, and authentic

If those resonate, read on.

The Impact You’ll Make

You’ll be the connective tissue between three hyper‑busy execs and a 30+ person (and growing) team spread across three time zones. Your super‑power isturning chaos into clarity—shielding calendars, triaging comms,and ensuring the right conversations happen at the right time, whether that’s an investor pitch, a board‑deck dry‑run, or a last‑minute flight to NRF.

What You’ll Own

Calendar Command

Ruthless prioritization across founder‑led sales calls, VC check‑ins, internal stand‑ups, in-person events and family blocks. You decide what gets a slot and what gets bumped—with context, not chaos.

Inbox & Comms Control

Zero‑inbox mindset. Draft replies, surface the signal, and chase the loose threads (investor intros, enterprise prospects, PR requests).

Meeting & Board Prep

Own agendas, minutes, and action tracking for LT meetings. Build crisp slides and packets for monthly board syncs; keep OKR dashboards current.

Project Orchestration

Partner with the COO to watch over cross‑functional initiatives—product launches, IRL team off‑sites, integration roll‑outs, locking down our new Toronto office—and nudge owners before deadlines slip.

Travel & Event Playbooks

Book end‑to‑end travel (Shoptalk, Shopify Editions, Merchant Meetings, Board meetings). Plan IRL weeks and retreats that feel legendary, not logistical.

Work with our CFO to file expense reports, reconcile corporate cards, and wrangle vendor paperwork so finance stays zen.

Culture Carrier

Pulse‑check team sentiment, drop timely Slack shout‑outs, and help live our values every day.

You Might Be the One If…

• Calendar‑tetris, inbox‑alchemy, and follow‑through are second nature.
• Excellent written voice—able to shift from investor‑polished emails to playful Slack updates.
• Fluent in Google Workspace, Slack, Notion, and Shortcut; quick to master new tools (we love AI copilots).
• Operate with discretion : board decks, cap tables, and funding docs stay locked down.
• Thrive amid ambiguity, juggle ten balls, and still find a way to automate the eleventh.
• Bonus points for experience supporting fundraising, PR cycles, or founder‑led enterprise sales.

Why Reactiv

• Moment of inflection : fresh funding, real product‑market fit, and triple‑digit growth ahead.
• High agency : you’ll shape how a fast‑moving company stays organized and intentional.
• Tight‑knit team : flat structure, zero politics, plenty of memes and emojis.
• Competitive package : salary + meaningful equity, full benefits, and flexible PTO.
