Our team has worked inside some of the world's leading technology and media companies.
Leila Ergul Demir
Founder
Leila brings 20+ years of experience in enterprise sales leadership, GTM strategy, and revenue operations across EMEA and the Americas. Her career spans senior sales and GTM roles at Microsoft and Spotify, where she led market operations, built and scaled revenue teams, and worked on global deal strategy. She also co-founded a startup, developing its sales process and GTM motion from scratch. She founded Partner UP to give B2B companies the GTM systems, revenue operations, and sales strategy they need to sell into enterprise accounts consistently and at scale.
Willy Hernandez
Head of GTM Engineering
Willy is a GTM engineer and 12-year sales veteran. He builds the production systems behind enterprise revenue motions: install-base visibility across complex product portfolios, automated cross-sell workflows, channel orchestration, and AI-powered tools that sales teams actually use. He is well-versed across the full GTM stack, including Salesforce, HubSpot, Outreach, ZoomInfo, Apollo, Clay, n8n, Make, Workato, MuleSoft, OpenAI, Anthropic, and Gemini. At Partner UP, he leads technical architecture and delivery for enterprise engagements.
Brandon Lennon
Senior GTM Engineer
Brandon is a GTM engineer who has sat in nearly every seat across the pipeline: demand gen, sales enablement, RevOps, and post-sale. That operator's lens, paired with deep fluency in AI and the modern GTM stack, shapes the systems he builds: AI-native revenue infrastructure that compresses the time between signal and action, built on a unified data foundation and designed to adapt as playbooks evolve. At Partner UP, he crafts the engines that run enterprise motions.

He has a proven track record of executing bold GTM strategies, designing effective sales systems, and building scalable B2B revenue growth engines.
