Account Executive - Commercial

About RunSybil

Founded in 2023 by Ari Herbert-Voss and Vlad Ionescu, RunSybil is on a mission to automate hacker intuition. We’re building Sybil: an AI-driven pentester that discovers vulnerabilities before they’re exploited. As adversaries adopt AI to increase their attack surface, we’re putting cutting-edge offensive security into the hands of defenders. Backed by strong investor support and early customer traction, our team is composed of experts from OpenAI, Meta, Mandiant, Palantir, Cruise, Trail of Bits, and Aptiv.

About the Role

We are looking for a Commercial Account Executive who will own the full sales cycle across mid-market security buyers. You will build pipelines from scratch, run deals with technical buyers at growing companies, and work directly with our leadership team to sharpen how we position and sell Sybil in a segment that moves fast and rewards credibility.

This is a role for someone who finds their own opportunities, builds their own process, and closes deals without waiting for a playbook. As our first AE, you will help define what commercial sales looks like at RunSybil.

What You'll Do:

• Own the full sales cycle on commercial accounts from first outreach through close, including renewals and expansion

• Build and manage your own pipeline through outbound prospecting, referrals, and partner relationships

• Run discovery and partner with sales engineering to run demo calls with security practitioners and security-minded engineering leaders, diagnosing their environment well enough to position Sybil with specificity

• Develop and maintain relationships with channel partners to source and accelerate deals

• Work closely with Customer Success to ensure clean handoffs and healthy accounts after the deal closes

• Feed signal from the field directly back to product and GTM leadership. What you hear on the front lines shapes how we sell and build

• Build sales workflows that turn individual wins into repeatable, scalable processes

• Represent RunSybil at security conferences and industry meetups, building relationships and generating pipeline in the rooms where our buyers already are

What You Bring:

• 5 or more years of full-cycle sales experience in cybersecurity or an adjacent technical space, with a track record in commercial or mid-market segments

• Genuine comfort in technical conversations with security practitioners, you do not need to be a pen tester but you need to understand the problems they solve

• Experience building pipeline from scratch, not just working inbound or handed accounts

• Familiarity with channel partner dynamics and the ability to build and close business through resellers

• Startup sensibility: you move fast, make smart decisions with limited information, and treat company resources like your own

• Instinct to build structure where none exists, identify solutions to future problems, and make improvements on your own terms

• Track record closing $30,000 to $100,000 ACV deals in environments where the buyer cares about technical depth, not just price

Location: Hybrid (SF or NYC area preferred, with remote flexibility)

Compensation: $180,000 to $200,000 OTE with equity. Comp structure and details shared with candidates who advance.


Diverse teams build better products. RunSybil is committed to hiring people who bring different perspectives, lived experiences, and backgrounds to our work. We encourage candidates of all races, ethnicities, gender identity and expression, sexual orientation, disability or medical conditions, ages, religions, and socioeconomic backgrounds to apply. Pursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records. If you're excited about this role but don't check every box, we still want to hear from you.
