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.

Had the pleasure of working with Esteban. He is very knowledgeable and and expert in Clay and the whole GTM stack. He's more than a GTM engineer, a true systems architect.
An expert in his craft

Working with Esteban is a pleasure. He is an expert. He cares. He understands the details. He learned about our business and space quickly. He is constantly thinking about getting results, not just doing the work. He provided us with tier-1 services in breaking down a complex problem into simple steps and building a machine. I only have great things to say about Esteban and recommend him enthusiastically.
