About Us

At Marble AI, we're building AI infrastructure for the future of tax firms.

We started with an AI-powered tax research platform used by hundreds of tax professionals today — helping firms research faster, draft faster, and deliver higher-confidence client work with citation-backed answers. But that's just the beginning. Our long-term vision is much bigger: transforming how accounting firms operate end-to-end through AI-powered workflows and automation.

About the Role

This is not a traditional SDR role. This is a founding commercial role for someone who wants more ownership, more responsibility, and more exposure than a typical SDR position provides.

If you are a top 10% BDR/SDR performer and are looking for an opportunity to grow quickly inside an ambitious early-stage company, we want to talk to you.

Why This Role Is Different

Most SDR jobs are:

• Highly repetitive

• Heavily scripted

• Narrowly scoped

This role is different.

You'll work directly with the CEO and leadership team as part of building and scaling Marble's go-to-market motion.

We already have strong foundations in place — including active pipeline sources, conference strategy, outbound infrastructure, and early customer traction. Your role will be to execute aggressively, test what works in-market, provide feedback from prospects and customers, and help us continuously improve the playbook.

This is a highly collaborative role where speed of learning matters. We value people who are curious, observant, adaptable, and excited to help refine a fast-growing GTM motion through real customer conversations.

You'll also be joining Marble at a unique moment. AI is rapidly reshaping the accounting industry, and tax firms are actively looking for solutions that help them work faster, more efficiently, and more strategically.And importantly: our customers actually answer their phones. Tax professionals still operate in a relationship-driven industry. Phone conversations work here. Conferences work here. Fast follow-up works here. That creates a huge opportunity for someone who is great at building trust quickly and moving fast.

What You'll Do

This is a highly hands-on role combining outbound prospecting, conference selling, demos, closing, and GTM experimentation.

• Attend conferences across the U.S.

• Run outbound phone and email sequences

• Prospect and manage your own pipeline

This is a high-ownership role for someone excited by ambiguity, speed, and building.

What We're Looking For

• You're highly comfortable on the phone

• You're curious and ask great questions

You do not need:

• Enterprise AE experience

We care far more about:

• Hunger

• Execution

• Curiosity

• Adaptability

• Track record.

What Success Looks Like

• Creating pipeline

• Converting prospects into customers

• Improving our playbooks

• Helping shape our GTM motion

You'll have direct visibility into how an early-stage company grows from early traction into a scalable revenue engine.

As Marble grows, this role can evolve into:

• AE

• SDR leadership

• GTM operations

• Broader commercial leadership.

• Reporting To: CEO to start

If you're sitting in a traditional SDR seat today thinking: "I know I can do more than this" — we'd love to hear from you.

Compensation Range: $78K - $120K
