Choosing a web/mobile design and development agency is one of those times when everyone claims to be great. Impeccable portfolios, a barrage of buzzwords, “user-centric approach” everywhere.
Then the project starts and, suddenly:
- deadlines slip
- decisions become confused
- the design is attractive but unusable
- the ROI… remains just a promise
This doesn’t happen because “all agencies are the same”, but because the initial selection is often made using the wrong criteria.
This article won’t tell you that glueglue is the best choice.
It will do so between the lines, explaining how a well-run agency thinks — and leaving you to draw your own conclusions.
1. Portfolio: nice, yes, useful, maybe
The portfolio is always the first item on the list. And rightly so. But it’s very easy to look at it the wrong way.
The question isn’t “do you work in my industry?”
It is:
have you already tackled problems similar to mine?
An e-commerce, a SaaS platform, a mobile app or a corporate website might seem like different worlds, but they often share the same complexities:
- funnels to optimise
- users to convert
- systems to integrate
- internal teams to align
A mature agency doesn’t collect sectors. It collects solutions that work.
Case studies: if you don’t measure, you’re just telling stories
If a project is presented only as “design award-ready”, ask a simple question:
What results did it produce?
Conversions, retention, performance, scalability. Even a “we learned what not to do” is more honest than a perfect render.
(Side note: if an agency spontaneously talks about numbers before you even ask, that’s a good sign.)
2. Process: where you see if it’s a true partnership
This is where most illusions fall away.
Design and development: only separate in the slides
If design and technology are treated as two distinct worlds, the result is almost always:
- theoretically correct UX
- UI that’s hard to develop
- continuous refactoring
- late-stage compromises
A good partner designs already knowing what will happen next. They don’t design for Dribbble, but for real-world implementation.
Technologies: don’t ask what they use, ask why
React, Flutter, custom CMS, headless solutions. All legitimate.
The point is something else:
is this choice right for my project or just their comfort zone?
A professional agency will also tell you: “we could do that, but it’s not worth it”.
(And no, not all of them do.)
Communication: silence is never a good sign
Clear updates, defined milestones, structured channels.
If it’s not clear how you’ll communicate during selection, it’ll be worse during the project.
3. Timing and costs: the boring (but crucial) part
Quotations that are too low and aggressive timelines are attractive. For about two weeks.
Realistic estimates beat heroic promises
A trustworthy agency:
- sets boundaries
- suggests progressive roadmaps
- distinguishes MVP from “nice to have”
Those who always say yes often say it before really understanding the problem.
The perfect quote doesn’t exist, but a clear one does
A good quote isn’t the cheapest one, but the one that:
- explains what’s included
- clarifies what isn’t
- minimises future surprises
Transparency is an act of respect, not an extra.
4. Post-launch: when the real work begins
Getting the project online isn’t a finish line. It’s the start of the real work.
Maintenance, security, evolution
If no one mentions:
- updates
- support
- technical debt
…someone will pay for it later. Usually the client.
Control: trust, yes; dependency, no
Domain, hosting, CMS, repositories: these should be yours.
A partner confident in their value doesn’t need to tie you in with technical constraints.
5. The team: the people doing the work make the difference
You’re not working with the agency’s website. You’re working with people.
Always ask:
- who designs
- who develops
- who makes decisions
And above all:
is there a dedicated project manager?
Because even the best team, without someone directing them, produces just noise.
Honest conclusion: the right agency isn’t the perfect one
It’s the one that:
- understands your business
- takes a stand
- tells you when you’re wrong
- thinks in terms of value, not output
We strongly believe in this approach. And yes, that’s also why many clients choose glueglue.
Not because we are “the best”.
But because we work the way a serious digital partner should work.
If you want to check for yourself, do the best thing possible: ask tough questions. To us, as you would to anyone else.
