Growth Without Guesswork

Scaling a SaaS or tech startup is never easy. Juggling multiple hires for sales opps, marketing opps, AI workflows, data enrichment, personalised outreach, and the list goes on…., can quickly become unnecessarily complex, disjointed, and above all expensive.

As a Go-To-Market Engineer, my job is to bring this all together, taking oversight of each function and owning the Tech Stack.

This may include but is not limited to:

– ICP Definition & Targeting 

– Automation Sequencing & A/B Testing 

– Performance tracking & Data Analysis (turning data into actionable insights)

– Using the TAM Model (Total Addressable Market) to assess market share and potential for capture 

– Oversight of AI integration for Sales, Marketing, and RevOps 

Of course, this specialism is evolving daily and needs to be set up to respond to market trends and advancements in tech.

A GTM engineer should promote and facilitate cohesion across sales, marketing, and AE teams, encouraging cross-collaboration and open discussion. Each sub-team stands to benefit from signal analysis and performance data, enabling data-backed decisions to shape customer engagement strategy.    

In summary, my role as a GTM Engineer is to eliminate complexity, unify all key GTM functions, serve as the single source of truth for data analysis and performance tracking, and ensure every GTM initiative drives clear, measurable ROI.

Leading companies like Clay, Anthropic, and HubSpot have recently embraced GTM Engineering with great success—I’m committed to establishing myself as a leading voice and proven expert in this rapidly emerging field.

My career so far

Hi, I’m Jack, a Go-To-Market (GTM) Engineer with over 10 years of experience in sales, marketing, plus AI automation. My work journey began in the Royal Navy as an Electronic Warfare Specialist, where I developed a passion for data analysis and systems engineering. After transitioning to the private sector, I began working with SaaS companies, growth agencies, and tech startups to help them scale.

Along the way, I taught myself to code and build web applications. I became fascinated with AI and creating custom applications with agentic workflows, which predominantly focus on sales opps and marketing opps process automation.

I’ve spent most of my career solving complex problems in varied job roles, such as Electronic Warfare Specialist, Agency Solutions Consultant, Growth Marketing Lead, and Account Director.  

Moving forward, I’ve combined my coding and development skills with my sales and marketing experience to master go-to-market engineering. I’ve worked with sales automation tool providers, MarTech startups, SaaS businesses, marketing agencies and SEO consultancies. All these experiences and skills perfectly prepared me for my future as a top-performing go-to-market engineer.

I am a passionate, lifelong learner, driven by curiosity to continuously evolve my skill set and deliver maximum value across diverse projects.

My recent experience has focused on designing agentic workflows and advanced automation using platforms like n8n, Make.com, and CrewAI to integrate large language models (LLMs) effectively into sales and marketing processes.

Technical Skills:
Programming: Python, HTML, CSS, JavaScript, React Native, MERN Stack, Expert in WordPress, Docker, Cursor, Visual Studio Code, Jupyter Notebooks, GitHub,
AI & Data Enrichment: Clay, Apollo, Instantly.ai, Pinecone, LangChain, and API integrations with major LLM providers (OpenAI, Anthropic, Grok, DeepSeek)

Marketing & SEO Tools: SEMrush, Ahrefs, Screaming Frog, Surfer SEO 

In my previous role with Better Proposals, I led the growth marketing efforts and optimized technology stacks, gaining deep expertise in CRM systems, data enrichment services, and workflow automation tools.

Additionally, I have substantial hands-on experience managing advertising budgets exceeding a million dollars across platforms like Google Ads (including Performance Max), YouTube, Facebook, and Instagram.

As a Go-To-Market Engineer, my comprehensive blend of technical proficiency and strategic marketing expertise uniquely positions me to deliver impactful, ROI-driven solutions.
