Profile

Jo Cern

Technical credibility, commercial nerve, C-suite access.

Master's-qualified business computer scientist with 20+ years closing complex, multi-stakeholder deals across government, Big 4 and multinational accounts. I authored the SOW and technical case that brought the CEO-led team over the line on a $2M+ PwC engagement — the largest in the company's history — and negotiated a $250K commercial exposure off the table at a Big 4 steering committee.

In a dedicated new business role I won a competitive tender worth ~US$360K against incumbent vendors. I have also sat on the buying committee itself, evaluating vendors and approving enterprise software spend at HLB Mann Judd and ESV — which means the approval process, the stall points and the real decision-makers are already familiar ground.

That combination is what makes enterprise AI and cybersecurity deals closeable, not just presentable.

The differentiator

I sell to committees because I have sat on them.

Most enterprise sellers learn the buying committee from the outside. I spent four years as a voting member of one at HLB Mann Judd, and another at ESV — evaluating vendor proposals, running comparative product analysis and approving enterprise software spend. The approval process, the stall points and the real decision-makers are already familiar ground.

Running the deal from discovery to signature.

Technical pre-sales, solution scoping, SOW authorship, tender response and the commercial negotiation itself — including the conversations that go badly before they go well.

  • Technical credibility by training

    A master's in Business Computer Science means discovery with engineering and IT leaders happens without a solutions engineer in the room.

  • Concession strategy, not concession cash

    Faced a Big 4 steering committee alongside the CEO and traded access to existing reports rather than conceding $250K of scope.

  • Incumbent displacement

    A dedicated new business role, 100% new logo: senior stakeholder discovery, technical scoping, tender response, legal review and close.

  • Adoption is what renews the deal

    PROSCI-certified, with 630 seats and a measured 40% efficiency gain — the exact problem AI coding tools face once licences are bought.

Commercial recovery negotiated out of scope

Quantified an unfunded commitment made by a consulting manager, built the concession strategy, and faced the PwC steering committee alongside the CEO to negotiate the exposure out entirely — trading access to existing reports rather than conceding cash or additional delivery.
