Win the customers
that define the decade.
Femnexa is a strategy consultancy for data centre operators selling to hyperscalers, AI, and large enterprise. We help leadership teams sharpen their commercial offer, navigate complex deals, and build customer relationships that compound over decades — not a single deal.
Built by a Customer Expert who has sat on both sides of the table.
Wendy Crespo
Founder of Femnexa. 12+ years in customer-focused roles across data centres and telco — senior commercial positions at Six Degrees, Telehouse and Global Switch, most recently leading hyperscaler and enterprise account strategy at one of Europe's largest colocation operators.
I founded Femnexa because customer expectations have evolved faster than the playbooks operators rely on. As the industry has changed, customers have changed with it — they want to be partners, not transactions; involved, not handled; aligned on growth, not negotiated against. But the frameworks and tools that would make that shift real are still missing. Femnexa exists to close that gap.
Senior-led, senior-delivered, no hand-offs. Every engagement is led and delivered directly by me, bringing deep customer expertise earned from both the operational and commercial sides of the relationship.
Co-founder of the Forum for Women in Data Centres (FWD). Based in London, advising operators and investors globally.
Four ways to work together.
From a focused sprint to an ongoing partnership — chosen to fit the decision in front of you.
- Strategic counsel
- Commercial leadership
- Account interventions
- Programme design
Embedded Advisor
A senior peer alongside your existing commercial leader. Shaping go-to-market strategy, pressure-testing deals in flight, sharpening the thinking before key meetings, and providing the call before the call. Advisory, not operational — your team still owns execution.
Fractional Commercial Lead
Stepping into the commercial leadership seat itself — multiple days a week, owning customer strategy, key accounts, and team direction. For operators between commercial hires, post-acquisition resets, or first-time scale-ups, until permanent leadership is in place.
Account Strategy Reset
A deep, single-account engagement focused on one of your existing customers. Diagnose the relationship, build the retention or expansion plan, and shape the commercial narrative to take back to the decision-makers. Often the first move when a flagship account has stalled, is approaching renewal, or is ripe for expansion.
Customer Experience Toolkit
The framework, processes, and branded documents that turn your client approach from ad-hoc to repeatable. Onboarding packs, welcome guides, Quarterly Business Review templates, lifecycle artifacts — all bespoke to your operation and on your brand. For operators ready to scale customer-facing delivery with consistency.
Questions worth asking up front.
Why Femnexa over a bigger consultancy?
Femnexa is built for work that doesn't need a 12-person team. You get a senior Customer Expert who has done the work, no junior hand-offs, and pricing that reflects a single senior.
How does an engagement typically start?
A 1 hour intro call, no obligation, to understand your situation.
How do you scope and price?
Engagements are scoped individually. Most fall into three structures: a fixed fee for a defined sprint or diagnostic, a monthly retainer for embedded advisory, or a longer arrangement for fractional commercial leadership. Scope, deliverables, and pricing are always in writing before any work begins.
Where are you based — and do you travel?
London-based, working with clients across Europe, North America, and APAC. Engagements blend remote work with focused on-site time for customer meetings, leadership offsites, and key milestones. Travel is scoped in the proposal.
How is confidentiality handled?
Every engagement is covered by a mutual NDA. Client identities, customer details, and the work itself stay private by default. References are available after a fit is confirmed, on a case-by-case basis with prior consent from past clients.
