Sales Development & Prospecting Intern
The company
Management OS (mgmt-os.ai) is the AI-native management system built for the leader — the leadership execution layer above the revenue stack. It helps founders and revenue leaders see what changed, understand what it means, and know where to lead next — across the business, the team, and themselves. Behind it: a 500+ page management canon, 56 agentic automations, 400+ integrations, and a patent-pending system, built on twenty years of scaling revenue organizations ($8M to $87M through IPO; $50M to $8.2B across 10,000 sellers in 34 countries). Delaware C-Corp, Stripe live, founding cohort underway. Pre-revenue, deliberately bootstrapped, building its go-to-market pod as three fractionals plus an AI agent workforce — and now a small bench of exceptional interns.
Why this internship is different
We are not Meta, and this is not a fetch-coffee internship. The honest trade is this: we pay $15/hour (plus academic credit where your school offers it), and in return you get something most internships can’t buy — real ownership of real work, direct mentorship from a founder who has scaled revenue organizations to billions, and a documented path from intern to paid contractor to founding-team status as the company grows. The “grunt work” here — building awareness, educating buyers, engaging the ICP — is the work that decides whether a startup lives. You will own a slice of it, see your impact in the numbers, and learn the operating system of a company from the inside.
What you get: Direct founder mentorship coached against the Mgmt OS competency models · a portfolio of shipped, real work · a credible path to paid and founding-team roles · a strong reference and LinkedIn recommendation on completion.
The bar — the three qualities we hire for
Credentials are secondary. Across every role below, we screen first for three qualities, in this order:
- Hunger / drive / ambition. You want more than a line on a résumé. You move fast, take ownership, and treat this as a chance to prove what you can become.
- Curiosity. You ask why. You want to understand how revenue, products, and companies actually work — not just complete the task in front of you.
- The ability to figure things out / resourcefulness. You hit a wall and find a way around it — a search, a tool, an AI agent, a smart question — before raising your hand. You are AI-native by instinct.
Everything that follows — the roles, the outcomes, the deal-breakers — is downstream of these three.
How we hire (fast, structured, mutual)
- Apply with an artifact you made — anything you shipped, built, wrote, sold, or organized beats a résumé (résumé optional).
- Four short application questions (below). Caps are part of the test.
- A 30-minute conversation with the founder — behavioral, evidence-based.
- A small paid trial task (2–4 hours) on real work. You see the company; we see how you think.
- Decision within 10 days. Every applicant gets a response within 72 hours.

Mission
Build the ICP target universe and keep the CRM true
Best-fit talent
Sales, business, entrepreneurship — with grit
The work
- Build net-new target lists against the canonical ICP using Apollo and ZoomInfo (scaling AI-native / B2B SaaS, $3–30M ARR, 5–30 reps on HubSpot).
- Research accounts and contacts — the triggers, the people, the why-now — and write tight account notes.
- Keep HubSpot clean and true: dedupe, enrich, correct, and maintain field discipline.
- Support outbound sequences mapped to the six canonical trigger classes; track responses and follow-up SLAs.
- Sit in on discovery and close calls; capture notes and next steps.
What “great” looks like — the spine of the role
- A growing, enriched, ICP-matched account universe added every week.
- A CRM the team can trust — measurably cleaner than you found it.
- A reusable trigger-class research library that makes outreach sharper.
- Qualified conversations sourced and teed up for the seller and founder.
What you’ll learn
Full-cycle selling, evidence-based qualification (the Mgmt OS Opportunity OS / MEDDPICC lineage), CRM-as-truth discipline, and the structure of a real ICP and territory — coached against the 17 Sales Competencies.
Who you are
- You are hungry and resilient — rejection doesn’t rattle you.
- You are meticulous; you actually enjoy a clean system.
- You are curious about how deals are really won.
- You are resourceful at finding the right account and the right person.
Deal-breakers (any one ends the conversation)
- Won’t keep the CRM true — here the CRM feeds the product itself.
- Activity-without-learning: lots of motion, no reflection.
- Spray-and-pray instead of researched, targeted outreach.
- Treats AI tooling as a threat rather than leverage.
