Founding Business Development Representative

Join to apply for the Founding Business Development Representative role at Rex

Rex is a privately held ecosystem of entrepreneurial ventures led by Peter Rex, spanning real estate private equity, technology, insurance, and AI. We build businesses and investment platforms that generate both exceptional financial returns and meaningful societal impact. At the core of our strategy is investor engagement: attracting aligned capital partners who share our long‑term vision. We are building the most compelling investor‑facing ecosystem in the private markets.

The role offers exposure to a uniquely diverse platform; combining institutional‑quality real estate and high‑growth tech ventures, all aligned under a singular mission‑driven vision.

Rex is building a diversified portfolio of AI‑powered tech products that solve real operational problems across multifamily, insurance, private equity, and real estate. Backed by deep domain knowledge and direct access to 50,000 residents, $5B in real estate assets, and 1M+ units via strategic partnerships, we develop products that are tested, refined, and deployed  operate across eight live tech products today, driving measurable results in automation, decision‑making, compliance, and payments.

From invoice processing and vendor credentialing to maintenance operating systems and conversational AI, our tools are saving thousands of hours and generating real ROI. Our 500+ teammates are united by a mission to catalyze human flourishing: building, testing, and scaling tools that serve real people in the real economy.

Rex Tech is seeking Founding BDRs (Business Development Representatives) to ignite go‑to‑market momentum across our portfolio of ten AI‑driven technology ventures, each conceived and built from scratch and now generating revenue, with several products led by established leadership teams and scaling, and others emerging from zero to one and fully go‑to‑market ready. This is a front‑line, zero‑to‑one role for people who want real responsibility, real pressure, and real upside.

You will generate demand from scratch, drive aggressive outbound, and build the pipeline that turns early traction into scalable revenue, reporting directly to the Head of GTM and working on one and likely multiple early‑stage products simultaneously to help break through from first customers to repeatable growth. You will test and refine messaging in real time, experiment across channels, capture raw market feedback, and convert signal into qualified opportunities that become meaningful deals, working shoulder‑to‑shoulder with product, engineering, and leadership to shape how products are positioned, sold, and adopted.

We are looking for candidates with 1–2 years of B2B sales or customer‑facing experience who are fundamentally builders at heart: hungry, scrappy, resourceful, relentless, fast‑moving, comfortable with ambiguity, rejection, and iteration, and obsessed with output, learning rate, and impact. This role is for someone who wants to earn their stripes the hard way, build real go‑to‑market skill at the earliest stage, and help take products from zero to scale, and who is missionary to the bone and deeply aligned with Rex’s mission to catalyze human flourishing through tech.

Fully remote, with a strong preference for Austin as a home base.

The Business Development Representative (BDR) will partner closely with the Product and Sales Team to fuel early‑stage pipeline growth for Rex’s emerging B2B technology ventures. This role is about driving the first spark of momentum, identifying target accounts, initiating conversations, and booking qualified meetings that lead to pilots and revenue. You’ll be on the front lines of customer outreach, ensuring our innovative products land in the right hands and helping shape how we go to market.

This is a high‑activity, results‑driven role suited for someone eager to break into technology sales, thrive in a fast‑paced environment, and work shoulder‑to‑shoulder with the team.
