GTM-first automation agency · B2B · B2C · D2C · B2B2C · Global

The go-to-market systems behind
growing businesses

Outbound engines, inbound speed-to-lead, CRM and RevOps automation, AI SDRs, lifecycle messaging and the reporting that shows what worked — built on n8n, Clay and your stack, measured in revenue.

We start from your revenue motion, not a tool. Fixed-scope builds, live in two to four weeks, run with you until the number moves.

What a GTM-first agency builds

Four systems that move pipeline

Outbound Engine

Outbound Engine

•

Account lists built from your ICP, not bought and hoped for

•

Enrichment and a real first line per prospect, at volume

•

Sequences in Instantly or Smartlead, replies routed to your CRM

•

Deliverability, domains and warm-up handled as part of the build

Outbound Engine
Inbound Speed-to-Lead

Inbound Speed-to-Lead

•

Every form fill, call or WhatsApp message answered in under a minute

•

The right person gets a task, a ping and the context to respond

•

AI or human follow-up when nobody picks up

•

No lead waits four hours again

CRM & RevOps Automation

CRM & RevOps Automation

•

HubSpot, Salesforce, Zoho or Pipedrive that your team keeps up to date

•

Stage rules, hand-offs and de-duplication that run themselves

•

One source of truth for pipeline, not five spreadsheets

•

Reporting your leadership trusts on Monday morning

AI SDR & Voice Agents

AI SDR & Voice Agents

•

Enquiries qualified and booked around the clock, in your voice

•

Follow-ups that happen on day 3, 7 and 14 without a reminder

•

Hand-off to a human the moment it matters

•

Every conversation logged to the CRM with a summary

In their words — attributed by role and segment

What clients say

“Demo requests used to sit until someone noticed them. Now the rep has a Slack ping with the company's details before the prospect has closed the tab. Our median response is under three minutes and the pipeline from inbound has roughly doubled.”

Head of Sales

B2B SaaS · sales-led, inbound-heavy

“We had tried outbound twice and given up both times. HeiSyn rebuilt it as a system — lists, enrichment, the first line, the sending infrastructure, replies into the CRM. The difference is that it runs every week without me.”

FC

Founder & CEO

B2B services firm · outbound-led growth

“Abandoned carts, post-purchase and win-back now run on WhatsApp and email with the branching we could never set up ourselves. Repeat purchase went up and our support inbox went down in the same quarter.”

“Our front desk was missing enquiry calls during treatments. The voice agent answers, books into the real calendar and sends the confirmation. Patients think it is a person, and the no-show rate dropped because of the reminders.”

“The CRM finally reflects reality. Stages move themselves, duplicates are gone, hand-offs from SDR to AE do not drop, and the Monday dashboard is one link instead of four spreadsheets. Forecasting is possible now.”

“Sellers on our marketplace used to go quiet after onboarding. The activation sequence and the re-engagement triggers brought a measurable share of them back to listing, and we can see which message did it.”

“Every site visit and every follow-up is now automatic — enquiry in, agent assigned, visit booked, reminder sent, feedback asked. Our agents close more because they are not doing admin.”

“They asked which number should move before they touched a tool. That was the first time an agency did that with us. The build was scoped, priced and delivered as written, and the reporting shows the number moving.”

“Founder content on LinkedIn was something we always meant to do. Now the topics come from our sales calls, the drafts land in my voice, I approve, and it posts. Inbound mentions of the posts started within a month.”
