GTM Engineer · Manila, Philippines

EricsonDalusong

I design and run go-to-market systems end to end, from data and AI agents to the motions that drive revenue.

My story

Hungry, curious, and a little lucky.

I believe in giving first and solving problems for others. A little help goes a long way, so if I can help you, just reach out.

The early years
A rough start
My early career was a struggle. I couldn't land a job, my English wasn't good, and I had a hard time expressing myself. I was always in debt, had zero savings, and couldn't afford the things I wanted.
The pandemic
Stable, but scared
Then the pandemic changed everything. I finally had a stable job, but I was scared of losing it every single day.
2020
Becoming a VA
So I took a leap and became a virtual assistant (that's what we call it here in the Philippines). I started with a few small gigs, and I loved it. That shift made me hungry to learn, to grow, and to stay curious.
2021
Finding outbound
Then I got lucky. A client introduced me to outbound lead generation and marketing, and it opened up a whole new world for me.
2022-2024
Starting Lead Assassin
In 2022, I started Lead Assassin. Initially, it was a lead generation company. We ran outbound for over 143 clients and learned what actually books meetings, one campaign at a time.
2024
The transition
In early 2024, I discovered Clay. I got into the program, got certified, and taught everything I learned to my team. That took us from a regular lead generation agency to a Clay Certified Expert Partner, and we became a GTM engineering agency that builds revenue systems with Clay, AI, and a few other tools. Along the way, I became the first GTM Engineer in the Philippines and launched Clay Club Manila, the first GTM community in the country.
Today
Founding GTM Engineer
In 2026, I exited Lead Assassin to join a data platform company as their Founding GTM Engineer. On the side, I run in-person training events every quarter, teaching people how to become GTM Engineers. My life looks nothing like it did before, and I'm grateful for every step that got me here.

GTM Engineering

What I do as a GTM Engineer.

Day to day, my work sits between sales, marketing and the systems that connect them. Here's what that looks like for me.

Leading the GTM motion

I lead the go-to-market motion end to end, from who we go after to how we reach them and what happens once they reply.

AI agents

I'm the AI champion on the team. I test new AI agents as they come out, keep the ones that actually help, and turn what works into best practices for GTM.

Strategy and execution

I own both sides. I set the plan, then I build and run the motions behind it, the ones that turn into pipeline and revenue.

Teaching

I teach people how to become GTM Engineers through GTM Engineering Academy Manila. It's the course I wish I had when I was starting out.

Instantly Gold Award

5,000 B2B sales opportunities.

Instantly gave me this plaque for generating 5,000 B2B sales opportunities on their platform. Yes, that face is my real reaction. Not bad for someone who started with a few small VA gigs.

Community

Clay Club Manila.

In December 2024, I hosted a small meetup for outbound operators in Manila. It became Clay Club Manila, the first GTM community in the Philippines. Now it's 300+ members, and we get together every quarter to share what's actually working.
