Your full-time GTM Engineer hire is 3–6 months away. We ship the system now so your AEs get qualified meetings while you finish recruiting.
A GTM Engineer search takes 2 weeks 3–6 months. By month two, your AEs are sourcing prospects on LinkedIn — that's a $150K/yr seller doing $20/hr work.
Hiring is slow. The market for senior GTM Engineers is competitive; offers and counter-offers stretch the search across an entire quarter.
Pipeline goes to zero. Or your AEs spend half their week on LinkedIn sourcing instead of closing the deals you already paid them to close.
AI agencies sell glue. No-code Make.com wiring that breaks at 500 sends. Pretty Loom demos, fragile production behavior.
Offshore "Clay experts" sell spreadsheets. $50 enrichment exports, not production systems. You can't put a CSV on a sequence and call it infrastructure.
Python scrapers pulling funding rounds, hiring spikes, tech-stack changes, and product launches into Clay tables. Refreshed daily. Not a one-time enrichment — a flowing pipe.
Claude API generates openers referencing the specific signal per prospect — the funding round, the new VP hire, the launched feature. Not {{firstName}} token substitution dressed up as personalization.
Multi-domain, multi-inbox setup on Smartlead or Instantly. Warmup, SPF / DKIM / DMARC, inbox rotation, bounce isolation. Targets 95%+ inbox placement — measured, not promised.
AI classifies intent on every reply — positive, objection, OOO, unsubscribe — routes to the right AE, and books meetings into calendar without manual triage. Your inbox stops being a queue.
Wires into HubSpot or Salesforce. Slack alerts on positive intent. A weekly performance dashboard that tells you which signal type and sequence variant is actually paying the bills.
30 min. We learn your ICP, current stack, and pipeline targets. You decide if it's a fit — no pitch deck.
System gets built. Daily Loom updates. You see every Clay table, every sequence, every line of code as it ships.
Live sending starts. We monitor deliverability and reply rates, iterate sequence copy in real time against the data.
You either take the system in-house (full code transfer, no lock-in) or we run it ongoing as your fractional GTM eng.
Honest scoping at the start saves both of us a quarter. If any of the below describes you, we'll point you somewhere better.
Companies under 10 employees or pre-revenue
B2C / D2C brands — wrong motion entirely
Recruiting agencies — we've worked the space; it's not our focus
Anyone shopping for "lead lists" — we sell systems, not exports
Anyone who wants to pay per meeting booked
SourceLoop is run by Jakub Minařík — a Czech-based GTM engineer with 3 years of outbound systems experience. Background in Python automation, lead generation infrastructure across US and EU markets, and AI workflow development. Based in Prague, working US / UK / EU time zones.
AAAs sell no-code Make.com wiring at low margins. We write Python and build with engineering rigor. The systems don't break at 500 sends — they get more reliable as volume scales because we instrument them properly.
You should — eventually. The market for GTM Engineers is competitive and the hire takes 3–6 months. We bridge that gap so you don't lose a quarter of pipeline waiting. When your FTE starts, they inherit a working system on day one instead of a blank Notion.
Yes, for retainer clients. Build-only clients keep the system; we don't appear anywhere in it. Either way, your buyers never see "SourceLoop" — only your domains, your inboxes, your AEs.
No, and anyone who does is lying. We guarantee a working system with deliverability and AI personalization at industry-leading quality. Meetings depend on your ICP, offer, and AE follow-through — variables we can advise on, not own.
Lower overhead means premium engineering at non-US agency prices. We work US / UK / EU hours; invoicing happens via a US-friendly setup. No friction for US clients — just a better price-to-quality ratio than a SF agency carrying twelve account managers.
We'll diagnose your outbound, you decide if it's a fit. If we're not the right call, we'll tell you on the call.
