About the Role

We're hiring a Senior Strategic Accounts Manager to cultivate relationships with the largest, most complex real estate firms in North America, the accounts that manage $50B+ in assets, run multi-fund structures, and take 12 to 18 months to make a technology decision. These aren't prospects you close on a call. They're institutions you earn over time.

As a secondary priority you will also own Fifth Dimension's strategic partnership program: building and managing alliances with technology partners, channel and referral partners, and industry associations that accelerate our reach and credibility across the CRE ecosystem.

Reporting to the CEO, you will operate as the connective tissue between Fifth Dimension and the global institutions that define commercial real estate. This is a senior IC role.

This role is ideal for someone who:

• Understands that a 15-month sales cycle is not slow, its strategic

• Has navigated investment committees, board approvals, and multi-stakeholder procurement

• Thinks in terms of account architecture

• Sees partnerships as distribution infrastructure

• Knows the quarterly metrics or milestones needed to land the 15-month long sell.

What You'll Do

Cultivate Enterprise Accounts (the core of the role)

• Own a named book of Tier 1 enterprise accounts: institutional asset managers, mega-REITs, sovereign wealth-backed platforms, and large family offices

• Provide full transparency of progress through leading metrics, given the long deals cycles of Enterprise Accounts.

• Build trusted relationships with COOs, CIOs, CFOs, and portfolio managers across these firms

• Navigate complex buying processes with 5 to 10 stakeholders, budget cycles, IT security reviews, and investment committee approvals

• Develop account-specific strategies that map Fifth Dimension's intelligence layer to each firm's operational pain: fund-level data isolation, co-investor reporting complexity, acquisition integration

• Progress accounts from first meeting through proof of concept to signed enterprise agreement

Build and Manage Strategic Partnerships

• Develop channel and referral relationships with CRE consultancies, brokerages, and advisory firms that influence technology adoption, where success is revenue multiplication and not just logo borrowing.

• Establish Fifth Dimension's presence and credibility within industry associations: ULI, NAREIT, PREA, CREFC, and others that lead to preferential rates, placements, introductions and ultimately, deals.

• Create co-marketing and co-selling motions with partners that generate qualified enterprise pipeline

• Identify, negotiate, and operationalise partnerships with technology and integration partners (Yardi, MRI, Argus, and similar platforms)

• Track partner performance and ROI with the same rigour you'd apply to your own pipeline

Shape Market Strategy

• Contribute directly to Fifth Dimension's US enterprise positioning, pricing, and go-to-market strategy based on what you learn from tier-1 accounts

• Partner with Product, Solutions, and Engineering to translate enterprise requirements into roadmap direction

• Turn early wins into case studies and reference accounts that accelerate the next wave of enterprise deals

What We're Looking For

Must Have

• 7+ years in enterprise sales, business development, or strategic partnerships, with at least 3 years focused on commercial real estate or PropTech

• Experience at venture-backed startups and in financial services - could be with real assets or other asset types

• Proven track record navigating 12+ month enterprise sales cycles with $250K+ ACV outcomes

• Experience building and managing strategic partnerships with technology vendors, channel partners, or industry bodies

• Executive presence and credibility with C-suite stakeholders at firms managing $40B+ in AUM

• A consultative, relationship-first approach to business development. You sell by understanding, not by pitching

• Experience with complex, technical products (AI/ML, deeptech, fintech, or similar enterprise software)

• Based in New York. Willingness to work in-office 3x/week (Midtown Manhattan)

• Travel readiness: 25%+ for client meetings, industry events, and 2x annual London trips

Nice to Have

• Deep understanding of institutional CRE buyers: how fund structures work, how investment committees make decisions, what makes a COO say yes to new technology

• Existing relationships at target accounts: Blackstone, Brookfield, Starwood, Mitsui, or similar institutional platforms

• Familiarity with CRE technology ecosystems: Yardi, MRI, CoStar, Argus, DealCloud

Why Join Fifth Dimension?

You will own the relationships that define Fifth Dimension's enterprise future. This is not a role where you inherit an account list and maintain it. You will build the account and partnership architecture from the ground up.

• Work with a genuinely differentiated AI product that enterprise CRE firms need, not a nice-to-have

• Join at a Series A growth stage where your work directly shapes company trajectory

• Help build the category leader in AI-powered commercial real estate

If you want to build something lasting with the patience and precision it requires, we should talk.
