CRITICAL - Software Development Agency

Careful, steady software development for products that need to grow at a pace they can sustain.

We build products and teams in a relaxed, methodical way: start with something real, ship incremental improvements every sprint, and let the product grow as confidence, evidence, and funding grow with it.

Team retainers

Choose the team shape that fits the product and the pace you can support

Each retainer is tied to a practical team structure. The question is not how much software you want in theory, but what level of progress you can fund comfortably, sprint after sprint. The larger team, if one is needed, is still coordinated through a single technical lead so the working relationship stays straightforward.

Primary pathStarter team

US$900 per month from

Team Principal engineer with product and delivery guidance

Best for Prototype, first release, or an early MVP

Pace A calm early sprint rhythm with meaningful weekly progress

A lean team shape for getting something real in front of users without committing to more monthly spend than the product should carry yet.

Best when the product needs a clear technical foundation, early user feedback, and steady progress rather than a burst of unfocused build activity.

You still work through one technical lead, even if other specialist help is brought in as the product grows.
Well suited to clients who want to start with a practical skeleton app and improve it incrementally.
Keeps the monthly cost low enough to sustain while the product proves its value.
Works well when requirements are expected to change as real users respond.

Start with a paid kickoff

Retainer-firstCore product team

US$3,200 per month from

Team Senior engineer, delivery management, and specialist support when needed

Best for MVP through early growth

Pace Regular sprint-by-sprint improvement with room to adapt direction

A balanced team for products that need dependable shipping, thoughtful technical decisions, and enough delivery structure to keep momentum without waste.

This is the natural shape for a product that has moved beyond the first prototype and now needs disciplined iteration over time.

The client relationship remains simple, with one technical lead coordinating the wider team.
Suitable for founders who want a product to improve every sprint at a sustainable pace.
Good for products with active users, evolving priorities, and a need for clearer planning and execution.
Can be expanded carefully as the product and budget mature.

Discuss a core team

For greater pace or complexityScaled delivery team

US$7,600 per month from

Team Multiple engineers with senior oversight and extra specialist roles as needed

Best for Growing products, larger roadmaps, and more demanding delivery programmes

Pace Higher throughput, more parallel work, and deeper technical coverage

A broader team for products that know where they are going and need more implementation capacity without losing clarity, technical leadership, or cost discipline.

Best for products where a small team would become the bottleneck for pace, resilience, or technical complexity.

The mix of engineers can be tuned toward lower cost or higher expertise depending on what matters most for the product.
Lets CRITICAL add international expertise carefully instead of growing headcount too quickly.
Useful when integrations, product breadth, or delivery expectations increase materially.
Still structured around a sustainable monthly retainer rather than high agency overhead.

Discuss a scaled team

For existing teamsFractional technical leadership

US$1,400 per month from

Team Experienced engineering leadership layered onto your current team

Best for Existing products that need clearer direction more than extra hands

Pace Better planning, stronger decisions, and calmer execution with the team you already have

A lighter engagement for teams that are already building, but need steadier product and technical leadership before deciding whether to scale implementation capacity.

Ideal when coordination, architecture, prioritisation, or delivery confidence is the real constraint.

You keep one experienced technical lead as the point of contact rather than managing several separate contributors directly.
Often the lowest-overhead way to improve software decisions and delivery quality.
A practical option before committing to a larger multi-person team.
Helpful for companies that want honest technical stewardship without agency theatre.

How CRITICAL works

Start with enough structure to ship, then let real use guide what comes next

Kickoff

We use the paid kickoff to understand the product, set a sensible initial scope, and decide what should be put in users' hands first.

Retainer

We shape a monthly team around what you can sustain, then deliver in increments so the product can improve every sprint.

Adjustment

As the product grows, we can add capability carefully and only where it genuinely improves pace, quality, or resilience.

Transparent by design

A small agency, low overheads, and a clear cost model

We build teams internationally and keep the economics easy to understand. Contractor costs are passed through clearly. CRITICAL earns through a reasonable management fee for shaping the team, running delivery, and keeping the whole engagement calm and accountable. Clients work with one technical leader throughout, while the broader team is assembled to match the budget and the level of expertise required.

What you are paying for

Senior product and engineering judgment shaped by fifteen years of building software products and teams.
A single technical point of contact who understands the product, leads delivery, and keeps communication clear.
Clear delivery management, careful hiring, and the right expertise brought in when it is genuinely needed.
A team structure that can change with the product rather than locking you into unnecessary fixed overhead.

How we think about value

We try to pass on every sensible efficiency to the client and choose tools that fit the product, not the other way round.
We are comfortable using strong starter frameworks and auth foundations on day one if that helps get the right skeleton app live sooner.
If cost is the priority, we shape the team more economically. If expertise is the priority, we bring in more senior specialist capability and the cost rises accordingly.
We grow through long-term relationships, so the model only works if clients feel the costs stay reasonable and fair.

When to use CRITICAL

The agency suits products that benefit from patience, clarity, and steady improvement

Good fit

Products moving from prototype into MVP with a need to get into users' hands without overbuilding.
Teams that want regular delivery, calmer technical decisions, and room to adapt requirements as they learn.
Operators who prefer transparent costs and sustainable retainers over inflated agency packaging.

Not a fit

Buyers looking for aggressive sales language, inflated promises, or artificial urgency.
Organisations that want a large team immediately without first establishing what the product can sustain.
Customers outside the supported markets or expecting non-English communication.

Action paths

Two simple ways to begin

These links are placeholders for the final checkout and booking integrations. The structure is here so the site can point clearly to either a paid start or a relaxed fit-check conversation.

Paid kickoff

A short, paid piece of work to understand the product, outline the right initial team shape, and decide what should be shipped first.

Free intro call

A relaxed conversation if you want to check whether the working style, team model, and delivery approach are a good fit before committing.

Next step

If the approach feels right, begin with a kickoff and shape the team from there.

We do our best work when the relationship starts simply, the pace is sustainable, and the product is allowed to improve through real use rather than pressure.
