Jacob K.
GTM Engineer | Clay, n8n, HubSpot, SFDC, SFMC | Signal-Based
Stop scaling people. Start scaling systems. I'm Jacob, founder of Gamma Growth Partners, a GTM engineering and tech consulting firm. I build and run go-to-market infrastructure (data, signal, automation and AI) for B2B companies in technology, real estate, finance, professional services and insurance. Most companies don't have a lead problem. Their growth is linear because their go-to-market is manual: lists bought instead of signals tracked, outbound disconnected from the CRM, follow-up left to whoever remembers, and no clean read on what actually produced pipeline. THE GAMMA FRAMEWORK: FOUR LAYERS, BUILT IN ORDER 01 Data: CRM architecture, automated enrichment, deduplication, hygiene rules 02 Signal: the changes that precede a purchase (renewals, filings, hiring, leadership moves, intent) 03 Activation: signal-triggered outreach, AI research and drafting, lead scoring, routing 04 Measurement: attribution, pipeline reporting, cost per opportunity Most teams are missing two or three of these layers. That's where pipeline breaks. HOW WE WORK TOGETHER Point Solutions: one fixed-scope build, documented and handed over. Automated cold email, Clay table builds, CRM builds, LinkedIn automation, SEO, deliverability fixes, reporting dashboards. Integrated Systems: the builds you need, wired into one data spine, with an industry signal library, routing and scoring, cross-channel measurement, documentation and team training. Strategic Partner: a fractional GTM engineer embedded with your team. New signals and plays every month, campaigns and deliverability managed. Month to month after the initial term.

STACK Data: Clay, Apollo, HubSpot, GoHighLevel, Salesforce, Pipedrive, Attio Signal: RB2B, Common Room, PredictLeads, BuiltWith, SEC EDGAR, Firecrawl, Apify Activation: Instantly, Smartlead, lemlist, HeyReach, Klaviyo, Claude, OpenAI Measurement: Looker Studio, GA4, BigQuery, HockeyStack Orchestration: n8n, Make, Zapier, MCP, Supabase HOW I OPERATE You own every account, license and asset. I favor established platforms over clever ones and the fewest moving parts that work. Every build ships with documentation and a recorded walkthrough. Send me a message with your current stack and the motion you want to scale. I'll come back with where your system is leaking, the signals worth tracking in your market, and a scoped fixed fee.
