Esteban Lopez
B2B RevOps and GTM systems that scale. Advanced Artisan Clay expert. Salesforce and HubSpot certified.
Enterprise-grade revenue operations and GTM engineering for B2B teams that want systems built to scale, not another tool setup that breaks at volume.
Who this is for: B2B companies from VC-backed SaaS through enterprise, including SaaS, healthcare, recruiting, and security. Trusted by 25+ companies across 10 countries (AMER, EMEA, APAC), among them Newsweek, Veryon, Cryptio, Kumo, Moxie, Rollstack, YunoJuno, SlashExperts, and OurFamilyWizard.
The problem: enrichment, CRM, and outbound are bolted together. They work in a demo and break once volume shows up.
What we do: one accountable architect and a small senior team design the full go-to-market motion as a system: platform infrastructure, enrichment, automation, CRM, and custom AI agents. The build is rigorous, documented, and yours to own.
What is different: FuelGTM covers work a multi-person GTM team usually splits across specialists: GTM architecture, Clay engineering, CRM development, and custom software. AI augmentation (Cursor, Claude Code, MCP servers) is part of how we ship, so we solve problems configuration alone cannot. One partner owns both your CRM and your Clay workspace.
I am a Clay Advanced Artisan (top tier of the partner program and a First-100 Solutions Partner), a Salesforce Certified Developer and a Salesforce Certified Administrator, and HubSpot certified.

"Esteban is very skilled RevOps engineer. He has expert level knowledge in Salesforce development and can pretty much realize any custom functionality - whether it's by writing code or leveraging visual workflow builders. He is capable of breaking down complex requirements into actionable tasks, and if he doesn't know how to do something he goes out and figures it out. Esteban speaks fluent English so communication on calls is a breeze, and he is very passionate about the work he does."
Jeff Schnepple

"Highly knowledgeable in the GTM stack. He set up a solid foundation of our CRM (Salesforce) in a short period of time."

Use Cases
🧹 CRM Data Hygiene
Clean accounts, contacts, opportunities, and activity. Decide the standard and custom fields that matter, normalize identifiers, dedupe and merge records, and transfer related child records. Set record ownership, sharing, and visibility. Enrich missing fields. Orchestrate Clay and CRM sync.
🔁 RevOps Process Design
The Challenge Marketing, Sales, and CS operate in silos. Handoffs break. Nobody agrees on what a qualified lead looks like. How We Help We map your entire revenue process end-to-end, define lifecycle stages, build SLAs between teams, and implement the systems to enforce them — so nothing falls between the cracks.
🦾 AI Solutions & Agents
The Challenge You know AI could transform your GTM, but off-the-shelf tools are generic and your team's knowledge is scattered across docs, calls, and tools nobody can query. How We Help We build AI agents and RAG systems on your own data — meeting intelligence, account research, lead scoring, and personalized copy — grounded in your knowledge base so answers are accurate, not hallucinated.
👤 Marketing, Sales, Customer Success Workflow Improvements
Connect triggers and webhooks to the business process. Use AI steps to preprocess meetings and tickets, consolidate information, write summaries, fill sales frameworks, and update the CRM. Start the next step from the workflow automatically.
🧠 Custom Complex Orchestration
Multi-platform work: scraping, custom development, HTTP API endpoints, webhooks, application development, ETL, database connections, backup, and data consolidation.

Great collaborator
Sep 25, 2026
I had the pleasure of hiring Esteban as a fractional GTM engineer at YunoJuno. He quickly gets to the heart of a problem, turns commercial challenges into practical workflows, and explains them so everyone understands, not just technical people. An expert in Clay and HubSpot, he approaches enrichment, segmentation and automation with clarity and care. For any business seeking a fractional GTM Ops lead, Esteban is an excellent choice: technically deep, commercially sharp, great to work with.

Esteban helped us deploy our Clay GTM strategy and organize significant amounts of data. He was very knowledgeable and I'd be happy to work with him again.
Strong partner for complex Clay and GTM operations
Sep 23, 2026
Esteban brings strong Clay expertise and a good understanding of how to turn business goals into workable GTM solutions. He’s particularly good at thinking through complex use cases, structuring workflows, and finding creative ways to use Clay beyond basic enrichment. He has been a valuable partner as we’ve expanded how we use the platform, and I’d recommend him to teams looking for someone with deep hands-on Clay experience.
The go-to for Clay and GTM automation
Sep 23, 2026
Esteban did outstanding work helping us build out and integrate Clay into our tech stack. He automated lead identification and generation for us at both a macro & highly targeted level, from evergreen LinkedIn campaigns to sharp event-driven plays, and consistently delivered high-quality and results.
Beyond the output, working with him was a pleasure. He's a genuinely great guy who can move fast on his own but is just as easy to collaborate with. Highly recommended for your GTM and Clay needs.
HIRE THIS GUY

Esteban has been an essential part of building out our AI SDR program. He built the Clay and n8n work that powers the whole system, and his ability to translate complex workflow requirements into clean, reliable automations has made a huge difference in how fast we've been able to move. He's also been a key contributor to our Salesforce Account enrichment/dedupe project, bringing the same level of care and technical rigor to that effort. Esteban will teach you the know-how throughout the process
