Enterprise Account Executive (Founding Hire)

About Mission Inbox Mission Inbox is a B2B email infrastructure platform processing 80M+ emails per month for 130+ customers globally; including enterprise accounts paying us $240K+ per year. We're cash-flow positive, profitable, and growing 233% YoY with 139% NRR; early-stage growth without survival anxiety. We operate fully remote, globally distributed, at the execution standards of a company 10x our size. Our team ships three product lines we call "Cubes": Sales & Marketing email infrastructure, and Transactional email. Our AI Shield; trained on 90M+ emails; is the defensible moat in a category where deliverability gets harder every quarter. The Role You'll be Mission Inbox's first dedicated Enterprise Account Executive. We've proven the model; customers already pay us $60K, $120K, and $240K+ ACVs. Your job is to find more of them. You'll build and own a focused list of 80–100 named target accounts; Fortune 1000 marketing leaders, high-growth scale-ups with serious outbound or transactional volume, and platform companies whose email is mission-critical. You'll work both our Sales & Marketing and Transactional cubes, multi-threading across CMOs, RevOps, CTOs, VPs of Engineering, and Procurement. You report directly to the CRO. You'll partner with Marketing on 1:1 and 1:few ABM plays, and with our SMB Sales team for warm pass-ups from inbound. This isn't a lone-wolf seat — it's the lead role on a coordinated hunt. What You'll Do Own a named account list of 80–100 target companies across Sales & Marketing and Transactional cubes. Build it, hunt it, defend it. Land $60K+ ACV deals as your baseline, with $200K+ whale hunts as your stretch. Multi-thread accounts — 5+ stakeholders per opportunity: Marketing Ops, RevOps, CTOs, VPs of Engineering, Procurement, Security. Become the email infrastructure expert in the room — speak credibly about deliverability, sender reputation, IP warming, SPF/DKIM/DMARC, and the competitive landscape. Run procurement — security reviews, MSAs, DPAs, vendor onboarding. You'll inherit playbooks from our existing $240K deals. Partner with Marketing on ABM plays for your top 20 accounts. Partner with SMB Sales to catch upmarket signals from inbound. Shape the enterprise roadmap — you'll be closer to enterprise buyer requirements than anyone, and your input goes directly to product.
