MarTech (Marketing Technology)
What is martech?
- A collective term for software tools used in marketing
- The tech stack behind CRM, automation, analytics, and advertising
- The key is integration between tools
Building a martech stack isn’t about buying tools; it’s about turning the traces marketing leaves behind into a record you can reuse. Something like 'this customer came to last year’s seminar,' which lived only in one person’s head, moves into a field in the system, and from that moment the basis for decisions shifts from people to data. The first change teams notice in practice isn’t speed but repeatability. The same campaign can run again even when the owner changes, and you can explain why last year’s email went to that segment.
The stack is usually split into four layers: a collection layer that captures visits and behavior (web tags, CDP), a storage layer that accumulates customer data (CRM, DW), an execution layer that runs email, ads and campaign scenarios (MA), and a measurement layer that reads the numbers (GA4, BI). When one layer is missing, the numbers in the other layers get shaky too. Its center of gravity differs from adtech: adtech buys strangers on other people's media, while martech works the first-party data you already own. Marketing teams at mid-sized Korean companies typically use about 8–15 tools, licenses alone often run into the millions of KRW per month, and by most accounts about half of those tools run separately, unconnected to each other.
The most common misconception is that adopting a tool brings the process along with it. Even with marketing automation installed, if you haven’t agreed on lead scoring criteria with sales, sales won’t even open the leads the system flags as 'hot.' Tools don’t replace agreement between departments. The same goes for naming rules: if one company is registered three times as '(Co.) OO,' 'OO (Co.),' and 'OO Co., Ltd.,' every dashboard shows a different customer count, and from then on executives stop trusting the numbers at all. The harder part isn’t adoption but cutting the tools you don’t use: annual contracts quietly auto-renew, and license fees for tools nobody opens keep piling up.

Consider a hypothetical case: Company A, an industrial measuring-equipment manufacturer with 180 employees and about KRW 40 billion (≈ US$29,926,700) in annual revenue. Its marketing team has 3 people, yet it ran 7 tools, including web forms, an email sender, a CRM, and ad accounts. Leads were still compiled in Excel and emailed to the sales team, and sales kept saying, 'We hardly got anything.'
- When the marketing lead pulled the last 3 months of 1,240 leads into one sheet, 31% were duplicates, and the head of sales pointed to dropped handoffs, saying, "We got fewer than 400."
- When the CEO said, 'Let’s plug in a CDP first,' the marketing lead replied that this year’s goal is 40 consultation requests a month, and first canceled three tools that didn’t serve that goal.
- They connected web forms, the CRM, and the email tool in a single flow and standardized company names by business registration number, merging 380 duplicate records. The work took 2 weeks of outsourced development and cost KRW 9 million (≈ US$6,730).
- They sat down with the sales team and agreed on scoring criteria: 20 points for a price-list download, 40 for a demo request, and any lead scoring 60 or more would be auto-assigned in the CRM to the responsible rep. The sales director said, "That's worth opening."
- Six months later, lead-to-consultation conversion had risen from 8% to 17%, the average 3-day wait before a lead was handed off had dropped to 4 hours, and monthly license costs had fallen from KRW 3.2 million (≈ US$2,390) to KRW 1.9 million (≈ US$1,420).
