Helper CTO Series 08 | Hire an In-House Tech Lead or Go External: How to Actually Run the Numbers

"I've been thinking about hiring a tech lead, but I'm worried we can't sustain the cost, or we'll hire the wrong person." That hesitation is reasonable, but it usually gets framed as "how much does hiring someone cost versus going external, which is cheaper" — and that's the wrong comparison from the start. Getting it wrong costs a full year of payroll for a position with nothing to do, or saving money while nobody makes decisions for the system. It's not that your budget is too small — it's that you haven't figured out whether you're buying a person or a function. Here are three questions to help you get the math right.

First ask: do you need a person, or a function

What a company actually needs is a "function": someone making judgment calls for the system, someone accountable for keeping it out of trouble, someone who knows what to do next.

• An in-house tech lead delivers that function through one person: fixed cost, bounded knowledge, and it all walks out the door with them when they leave.
• An external tech lead delivers that function through a team plus a process: billed monthly, knowledge spread across several people, and a proper handoff when it stops.
• Neither one is inherently better — the difference is structure, and the right structure depends on where your company is right now.

Two options, laid out in one table

Don't compare salaries — compare what you actually end up carrying.

In-house tech lead: what you get, and what you carry

What you get is "someone always reachable," and someone whose understanding of your business keeps deepening — technical judgment fused with business judgment, which is hard for an outsider to fully replicate. If the company plans to build its own tech team eventually, this is the starting point. What you carry is:

• The hiring period: from the decision to hire to someone actually being up to speed, the system goes unwatched for months in between — and hiring the wrong person costs more than not finding anyone at all.
• Bounded knowledge: they know backend well, but server issues might still need an outside hire; they know servers well, but security might still need one too.
• Departure risk: the day they leave, you're back to square one, plus a system only they ever fully understood.
• Uneven workload: most small and mid-sized company systems don't need someone watching them eight hours a day.

Engineers are already hard to find, and tech leads are harder still — outsourcing thinking for a talent-scarce era covers what this means for small and mid-sized companies.

External tech lead: what you get, and what you give up

What you get is no hiring period, a team splitting different domains, the ability to stop anytime, and people who've already seen many different systems — the problem you're facing usually isn't their first time seeing it. What you give up is:

• Not being in the office: asking a question means scheduling time, not walking over and tapping someone on the shoulder.
• Business understanding builds up gradually: it grows the longer you work together, but month one will never match someone who's sat next to you for six months.
• Not touching business decisions: what products to sell, where the company is headed — that's not a tech lead's call to make.
• It's not the end point: if the goal is building a ten-plus-person internal team, external support can only help you get started.

A more complete comparison of outsourcing versus building in-house is in outsourcing versus building an in-house team for small and mid-sized businesses; worth adding — an external tech lead isn't the same as typical outsourcing, since it doesn't finish and leave; the details are in what is Helper CTO.

Three types of companies, three different answers

• The system is the company's product, and you already have several engineers: you need an in-house tech lead, the sooner the better. External support can hold the position until you find the right person.
• The system supports the business, and there's no internal engineer: this is exactly the situation an external tech lead suits best — what you need is judgment plus accountability.
• The system is small, rarely changes, and a day of downtime doesn't hurt: you don't need either — basic maintenance is enough.

Three questions can help you place yourself: what happens to the company if the system's down for a day? How much does the system need to grow over the next year? If you hired a tech lead right now, what would they actually be doing for eight hours a day? If you can't answer that last one, what you need isn't a person — it's a function.

What Nerdtechnic provides is that function

• No hiring period: the same team handles takeover, maintenance, improvement, and ongoing development, and can start once the system's been reviewed.
• Billed monthly, and you can stop anytime: basic maintenance starts at NT$6,000/month; a plan with development capacity is evaluated based on scope, at NT$30,000–200,000/month.
• When the engagement ends, the documentation and records are yours — switching to someone else doesn't turn into a black box.
• We're also clear about what we don't do: business consulting, business model planning, or pure staffing that just supplies hands without judgment.

When your company grows enough to hire in-house, our job is helping you bring that person on board and hand everything off properly.

If you're the second type of company, what we deliver as Helper CTO is exactly that function — like an in-house tech lead, just not on your payroll. The first step is a 60-minute system health check: we only need to see the code, no credentials to your production environment required, and within 3–5 business days you'll get a one-page report you can actually understand, then decide whether to work with us.
