The Moment You've Outgrown Your Dev Agency
A practical guide to building your own engineering team from someone who's done it
Dev agencies get a bad rap. And honestly? A lot of it is deserved. But here’s the thing... agencies aren’t evil. For many founders, they’re the right move early on. You need an MVP, you don’t have a technical co-founder, and were not ready to hire a full engineering team. An agency gets you from zero to something. That’s real value.
But the problem starts when “something” becomes your actual product. When customers are paying. When the product needs to evolve fast. And you realize that the people building your core business... don’t actually work for you.
That’s the moment most founders I talk to are in. Not angry at their agency. Just... ready for something more.
The Problem Nobody Talks About Publicly
If you look at dev agency reviews online, most are actually positive. Founders who had a good experience write about it. But the ones who got burned? They stay quiet. Nobody wants to publicly admit they spent six figures on something that didn’t work out.
So the real stories live in DMs. In “off the record” chats between founders. And what comes up over and over isn’t really about bad agencies... it’s about the gap between what the founder understood was happening and what was actually going on.
I would say this is the core of it. As a non-technical founder, you’re making decisions about something you can’t fully evaluate. The agency sends you a status update, it sounds great. But is it? You genuinely don’t know. And that’s not your fault. You shouldn’t need to read code to know if your product is on track.
This is actually the number one reason founders bring in someone technical on their side. Not to replace the agency. Not to fire anyone. Just to have someone who speaks both languages... who can sit in a technical conversation and then translate it into business impact. Like, “here’s what they’re actually saying. Here’s what it means for your timeline. Here’s what you should worry about, and here’s what’s fine.”
I did a technical audit for a B2B SaaS company, around 5 people, with a dev agency and a couple of “dedicated” engineers on their project. They had daily standups, things seemed to be moving but...
…the software was buggy and launch date was postponed over and over again!
Once I dug in, it was pretty straightforward. The engineers weren’t working with the urgency or ownership you’d expect from people building your core product. They didn’t understood the business nor critical user paths within the software, so they were just closing Jira tickets.
The Moment You’ve Outgrown the Model
There are signs. You start wanting to move faster than the agency’s sprint cycle allows. You want someone who deeply understands both, your codebase and the value you bring to your customers. You want to have a conversation about your product’s future and actually understand what’s realistic.
And to be fair... sometimes the answer is to stay with the agency. If you’re pre-product-market-fit and still figuring out what to build, a flexible agency relationship can totally make sense. But once you know what your product is and customers are paying for it, that’s when ownership starts to matter way more than flexibility.
So the question becomes: how do you make that transition without blowing things up?
How I Built a Team From Freelancers Up
A B2B SaaS startup, early millions in ARR, about a half-dozen people. I joined as their CTO. They had engineers from Upwork working “full-time”... I put that in quotes because these were freelancers billing by the hour with time tracking. It worked for a while.
The fear was real though:
“If we change anything, we’ll have downtime. Things will fall apart.”
I get it. When your product is live and customers are paying, the last thing you want is chaos. So I followed a rule I’ve learned the hard way: never break working systems.
I didn’t replace anyone on day one. Instead, I started evaluating. Not just code... the people. Who’s actually delivering? Who takes ownership? Who treats this like their job versus a gig between other clients?
The thing is, changing teams is hard. It’s always hard. But it gets way easier when the reasoning behind the changes is crystal clear. And that only really works with in-house people who see themselves as part of the product, part of the mission. Not contractors billing hours for a project they’ll move on from next quarter.
The engineers who genuinely stepped into that mindset, who showed up consistently and took real ownership... they stayed. They became the core of the new team. The rest were gradually replaced. And yeah, it wasn’t always smooth. There were moments where we were thin, where I had to jump in hands-on to make sure nothing fell over while we were between hires. That’s the part nobody mentions in the clean “we rebuilt the team” narratives.
It takes real work to keep the product stable while you’re changing the people building it.
But we got through it. Under six months, the team went from deploying once a month with a full week of release prep to shipping twice a week. And that’s the kind of change you feel across the whole company... sales can promise features with actual timelines, support can tell customers “it’s fixed” instead of “it’s in the queue.”
From One Team to Multiple Teams
Over time, I didn’t just build a team. I grew it into multiple teams with their own leads.
I found people within the team who could own entire areas of the product. Not just write code, but make decisions, communicate with stakeholders, run their own sprints. That’s when engineering stops being a black box and starts being a real department that product, marketing, and sales can actually work with.
And this is where I realized something about the CTO role that led me to what I do now. Most of what fills a full-time CTO’s week at this stage is stuff that doesn’t need a CTO. Status syncs. Routine decisions. Administrative work. All of that belongs with team leads and product managers.
The work that actually shapes a company’s technical future... architecture decisions, hiring strategy, process design, aligning engineering with where the business is going... that’s where the real outcomes come from. You don’t need someone doing that 50 hours a week. You need someone doing it well, consistently, with deep context.
What the Transition Actually Looks Like
I can tell you, founders always ask me “okay, but what does this actually look like week by week?” So here it is.
First couple of weeks, I audit what you have. Code, infrastructure, team, workflows. Real bottlenecks usually show up in the first few days... the rest is confirming and documenting.
First two months is the rebuild phase. Right people in the right seats, core processes in place. The team goes from shipping unpredictably to having a cadence you can actually plan around.
Months three to six, the team grows. Team leads emerge. You stop being pulled into every technical decision. Engineering starts talking directly to product and sales instead of everything going through you.
After six months... you get updates, not emergencies. The team and the knowledge belong to you. When someone leaves, the codebase and the processes stay.
That last part is what makes in-house different from agency:
With an agency, everything lives in their systems, their processes, their people’s heads.
The Cost of Waiting
I’m not going to tell you the sky is falling. But I will say this... every month you run with an engineering setup that can’t ship fast, the cost compounds.
Not just in money. In opportunities. Feature your customers asked for months ago that’s still “in the next sprint.” A competitor who launched something similar last week. A bug that’s been “almost fixed” for four weeks.
The companies I work with that are doing well right now... they all have one thing in common. They own their engineering. They’ve got in-house teams using AI tools to move faster, cross-functional workflows where product and engineering actually talk to each other, and a release cadence that lets them respond to market in days, not months.
Looking back at everything I’ve seen over the years, the founders who made the transition earlier always wish they’d done it sooner. And the ones who waited... well, they still got there eventually. It just cost them more.
The Question Worth Asking
If you’re working with an agency or outsourced team right now, ask yourself this: do you understand what’s happening in your own product?
Not “do you get status updates.” Do you actually understand what’s being built, why decisions are being made, and whether you’re on track?
If the answer is “not really”... that’s your starting point.
I’ve spent the last 15+ years building engineering teams in B2B SaaS and martech startups. If you’re thinking about making the transition from agency to in-house, or you’ve got a small remote team that needs structure and speed...
I’ll do a free 1-hour outside opinion with you.
No code access needed. Just screen share or send me a Loom of your setup, and I’ll tell you honestly what I’d change and whether you actually have a problem worth fixing.
