My free newsletter. Each issue opens up a real GTM system: Clay table logic, n8n workflow architecture, AI agent builds, and the frameworks I use with clients. One email per week, no fluff.

GTM ENGINEERING · APPLIED AI

I build GTM systemsthat compound.

Q: What is GTM engineering?

GTM engineering treats go-to-market as an engineering problem: data pipelines, workflow automation, multi-channel distribution, and AI agents built as production systems instead of manual processes. The test is simple: does it still run when the person who built it is on holiday?

Q: Who do you work with?

B2B SaaS companies, agencies, and startups whose GTM systems have to actually work: early-stage founders through enterprise revenue teams, across the US, UK, UAE, Singapore, Australia, and India.

Q: What tools do you use?

Clay for data enrichment. n8n for workflow orchestration. Claude and other frontier models for the intelligence layer. Instantly, Smartlead, and HeyReach for distribution. HubSpot and Salesforce for CRM. Vapi, Retell, and Deepgram for voice.

Q: How can I work with you?

Book a 30-minute call at cal.com/neerajkumar; you leave with a system sketch either way. For done-for-you GTM engineering, I take on a small number of build engagements directly. Courses and free resources live on this site.

Engineer, then sales leader, then GTM architect. I ship revenue infrastructure on Clay, n8n, and AI agents: still running a year later, documented down to the trade-offs.

Three incidents from GTM stacks I get called into

WARN: hours_lost/week > 15

Your best rep does data entry until lunch

Forty tabs open: LinkedIn, the CRM, a spreadsheet with formulas nobody trusts. Her first real conversation with a buyer starts at 2pm.

ERR: adoption_rate → 0

The AI pilot flatlined

Someone bought licenses, ran a workshop, shipped a demo. Ninety days later the login count sits at zero.

CRIT: bus_factor = 1

One automation, one owner, no docs

An API version bumps and the workflow dies quietly, sometimes for a week before anyone notices. The only person who can read it has a full calendar.

Most teams patch these incidents by adding another tool, which adds another failure mode. I fix the architecture instead: fewer systems, built to production standard, documented so they outlive their builder. That is the work I do.
