One focused sprint$4,000

Scope agreed before payment.

Your next release. Your way of working.

Extra engineering ownership for your product, or a delivery partner behind your studio.

For founders and product teams

Get an important feature out of the backlog.

Bring a defined feature, an overloaded roadmap, or a backend bottleneck. We take ownership of an agreed piece of work inside your existing codebase.

Work alongside your engineering team
Review progress through pull requests and daily updates
Keep the code, architecture decisions, and handover notes

Find a sprint for your product

For design and product studios

Take approved designs through to production.

Keep leading the design and the client relationship. We handle the agreed frontend, backend, and deployment work, under your brand or as a named partner.

Start from your approved Figma files
Agree milestones before you quote delivery to your client
Choose white-label or shared client communication

What could fit into one sprint?

A $4,000 sprint covers 10 working days across two calendar weeks. These are starting points for scoping; we confirm deliverables after reviewing your designs and code.

01 / Product feature

A focused onboarding flow

Turn a defined sign-up and onboarding journey into a working feature.

You bring: Approved screens, agreed user states, and an existing app with authentication.
We scope: Responsive screens, validation, agreed API changes, tests, and deployment.

Discuss this sprint

02 / Backend improvement

An export pipeline that keeps up

Move a slow CSV export out of the request cycle and into a background job.

You bring: An existing export, representative data, and access to your staging environment.
We scope: A queued job, progress or completion feedback, retry handling, and a before-and-after measurement.

Discuss this sprint

03 / Agency delivery

A designed page, ready to launch

Build an approved landing page or a defined set of product screens.

You bring: Final Figma files, content, assets, and the agreed hosting or app environment.
We scope: Responsive implementation, agreed interactions, browser checks, and a deployment handover.

Discuss this sprint

Every sprint ends with a handover.

Code in your repository, checks for the agreed flows, a demo, and deployment notes. Release access, acceptance criteria, and defect support are agreed in the written scope before payment. New features are scoped separately.

How a two-week sprint runs

Agree the deliverables before payment. Then build, review, and hand over in 10 working days across two calendar weeks.

Day 1: confirm the plan

The scope, acceptance criteria, dependencies, and release plan are already agreed. We confirm access and the implementation plan at kickoff.

PHPcreate_sessions.php Locked

Schema::create('sessions',
fn($t) => [
  $t->uuid('id')->primary(),
  $t->foreignUuid('athlete_id'),
  $t->timestampTz('started_at'),
  $t->integer('samples'),
  $t->jsonb('summary'),
  $t->timestampsTz(),
]);

Sprint 14 scope: 6 tickets, 2 endpoints.

Days 2–9: build and review

Commits and pull requests in your GitHub or GitLab, tickets moved in Linear, and a short Loom or Slack update each day.

Questions

The short answers. Anything else: email us.

Why sprints instead of billing hourly?

A sprint pays for working software, not time sheets. You agree the deliverables, acceptance criteria, and fixed price before payment. Each sprint covers 10 working days across two calendar weeks.

How do you handle scope changes during a sprint?

We review the effect on scope together. An equivalent task can replace an unstarted item by agreement; larger changes need a revised scope or a later sprint.

We already have an engineering team. Does this work?

Yes. We plug into your Git workflow, review pull requests, and take ownership of dedicated modules or services.

How soon can a sprint start?

We confirm current availability, access requirements, and a kickoff date when we discuss your scope. No sprint is reserved until the scope and start date are agreed.

Who owns the code?

You do. Everything ships to your repositories, with full IP ownership from day one.

Can we pause or cancel the retainer?

Yes, with one sprint of notice. There is no long-term contract.

What happens after delivery?

You receive the code, a demo, and handover notes. Defect support and any response window are defined in your written scope before payment. New features and ongoing maintenance are agreed separately.

Can you work under our agency brand?

Yes. We agree whether to join your internal workflow, communicate with the client under your brand, or work as a named delivery partner before kickoff.

Who is on the team?

A lead engineer who owns the architecture and the scope, and two senior engineers. All three write code. No juniors and no hand-offs.
