The Opportunity We’re seeking a scrappy, high-output GTM Manager to help launch and scale our early-stage B2B technology ventures. This is a hands-on role for a top 5% performer; someone who thrives in ambiguity, relishes early traction-building, and is eager to roll up their sleeves to drive the first wave of revenue. This is not a role for a polished sales VP or a purely tactical SDR. We're looking for an entrepreneurial executor who blends hustle, creativity, and cross-functional savvy to bring proven tools and products to market. You’ll work closely with our senior GTM advisor and product leads to validate demand, secure early customers, and build the foundation for a repeatable commercial engine. The Role The GTM Manager will lead on-the-ground efforts to commercialize new technologies within our ecosystem. This means identifying early adopters, initiating outreach, conducting demos, securing paid pilots, and working with product teams to adapt offerings for external use. Key Responsibilities - Own outbound GTM execution: cold outreach, booking meetings, pitching, and iterating on messaging - Build first pipelines through creative outbound, LinkedIn, and event-based channels - Develop sales scripts, objection-handling guides, and slide decks from scratch - Work directly with engineering/product teams to tailor offerings to customer needs - Run fast, scrappy campaigns to test messaging, pricing, and positioning - Launch pilot programs and close early POCs with clear ROI - Capture early customer feedback and help shape the GTM playbook - Lay groundwork for scalable commercialization: basic CRM setup, reporting, and sales operations Ideal Candidate Profile - 5-9 years of experience in early-stage B2B tech - Hands-on, GTM executor; not afraid to cold call, pitch, or experiment - Startup grit: thrives in fast-paced, high-ambiguity environments - Hunter mindset with a builder’s mentality - Strong communicator who can synthesize feedback and act fast - Cross-functional collaborator who can translate between product and customer - Self-directed, coachable, and obsessed with delivering value Rex Ecosystem-Wide Mission Catalyze Human Flourishing through our products/services and to elevate/further humanity in all our business dealings. Rex Values / Rex Culture - Customer Fanatic. We fanatically focus on customers, seeking to ever-deliver more value, and inventing/innovating on their behalf. - Product/Service Passion. Our business thrives or dies by products/services. - Ludicrous speed. Our default pace is extremely fast. Time is precious, life is short; and moving fast is more fun and effective. - FAWOMO. We will find a way, or make one. - Loves going to war: prefers wartime to peacetime, always hungry to move forward, do more, and push growth. - Chutzpah. Nothing ventured, nothing gained. Fortune favors the bold. Duc in altum. - Fun. We should only do work, over the long run, that’s fun; and work with fun people. Jokes and humor welcomed; PC stuff and uptight behavior prohibited. - Never-lose-money approach. Protects the downside, using careful analysis before deploying significant resources, and ensuring cash is plentiful; never risking what others have and need for what they don’t have and don’t need. - Other-centered. Idealist, desperate more than anything to leave an impact with their life by helping other people, seeing money as a means to serve. - Creative cost cutting constantly. There's always a smarter way, always room to cut, always ways to do more with less – a cost advantage is a competitive edge. - Fewer, more capable. Bias to as lean of a team as possible, with the highest competency – reducing communication and coordination, creating more effectiveness. - Underdogs. What we’ve done is nothing compared to what we’re going to achieve now. We’re fighting to be the best, clawing and biting up and forward, aiming to be the champs, be #1. Scrappy AF no matter how much we accomplish. We’ve never ‘arrived’ in our minds. We’re the underdogs always. - Other attributes valued. Pointblank forthrightness in conversation with teammates, brutally facing problems; velvet glove with iron fist in human dealings; shrewd as a serpent innocent as a dove; hardcore work hustle; invictus mentality; swagger with humility; quiet professionalism; thrifty and not materialistic; loves who they work with, loves what they do, and loves who we serve.
