Isabel Londono
Fractional GTM Leader
Who Isabel works with
Isabel Londono is a Fractional GTM Leader for mid-market B2B and B2B2C companies, typically generating $20M–$100M in revenue (and up to $150M for select engagements). Isabel is GTM OS Certified, trained in GTM Partners' proven GTM expertise, frameworks, and systems. She primarily works with VC- and PE-backed growth-stage companies in Ethics & Compliance SaaS, e-learning, and Fintech & Financial Services Technology, including payments, card networks, credit bureaus, and risk or data services. Her clients operate across multiple regions or global markets and sell to CEOs, COOs, CROs, CMOs, and RevOps leaders.
The GTM problems Isabel solves
Isabel addresses the Growth Gap that occurs during international expansion or post-acquisition commercial integration. She solves challenges such as inconsistent growth and win rates across global regions, domestic playbooks applied abroad without localization, fragmented CRM environments, low trust in BI metrics, and pricing or packaging complexity that slows sales velocity. Working across marketing, sales, product, and customer success, Isabel aligns cross-functional teams around a unified revenue architecture. She uses the GTM Operating System (GTM OS) to fix post-acquisition commercial misalignment and drive growth efficiency under board or PE pressure without requiring additional headcount.
Track record
Isabel brings more than 20 years of operating experience leading commercial and go-to-market strategy. Her past leadership roles include serving as General Manager of LRN's mid-market segment, Managing Director of Customer Acquisition at BMO, and Head of International Marketing at TransUnion, where she built commercial teams across six global regions. Through her advisory firm, WorldWise Strategy, she uses proprietary frameworks alongside GTM OS methodology to help mid-market organizations translate global expansion and M&A investments into measurable business outcomes.
In Isabel's words
I help mid-market B2B companies (typically $20M–$100M revenue) navigate complex growth events—like international expansion and acquisitions—by aligning GTM across markets, offerings, and commercial teams to maximize the return on those investments.
Why hire Isabel instead of a traditional fractional executive?
Isabel is a GTM OS Certified fractional GTM leader, trained in GTM Partners’ proven GTM expertise, frameworks, and systems.

Capital is no longer cheap. You get senior GTM leadership and a proven operating system without the full-time executive price tag.
You hire the result, not the role.
