Our product development services are fixed-price sprints for features, fix lists and MVPs with a written brief: one quote, one delivery date, and tested code in your repository. White-label on request.
Fixed quote within two business days of the scoping call.

The basics
What are product development services?
Product development services turn a product idea, feature list or fix list into working, tested software. Ours are fixed-price sprints: you bring a written spec, we quote once, and we deliver tested code to your repository on an agreed date, with documentation and a warranty.
Each sprint is built with AI agents and reviewed by a senior engineer, so you get the speed of AI-assisted development without unreviewed code. You see progress in your repo and a written update every working day.
It is fixed-price software development for work that can be specified up front: an MVP, a feature or integration, or the top items from an audit. Work that changes week to week suits an embedded engineer better.
Who needs product development services?
Agencies with a sold build
You sold the project and need an engineering bench that ships while you sleep, under your name.
Founders with a spec and a date
You have a written spec, wireframes or a prioritized fix list and a date you can't move.
Teams after an audit or analysis
You have a report and want its top items built, at a fixed price.
Not for projects without a brief
No written brief yet? Start with an AI integration analysis or a code audit, which produces one.
Deliverables
What do our product development services include?
Every sprint, whatever its size, includes the same six things.
30-minute scoping call
You walk us through the brief; we ask the questions that would otherwise become change requests.
A fixed written quote
Scope, price, date and acceptance criteria in writing, within two business days.
AI-assisted, senior-reviewed build
AI agents draft, a senior engineer reviews and tests, and the code lands in your repo.
Daily written updates
Progress you can see in your repository and a written update every working day.
Acceptance testing
You test against the agreed criteria; we fix anything that misses them at our cost.
Handover and warranty
Documentation, deployment steps and a 30-day warranty on the delivered scope.
Process
How does a fixed-price product development sprint run?
From the first call to handover, a sprint takes 2–6 weeks. Your team spends its time on the scoping call and on acceptance testing.
| Stage | What happens | What your team does |
|---|---|---|
| Scoping call | 30 minutes on the brief; open questions answered before they become change requests | Walk us through the spec |
| Fixed quote | Scope, price, date and acceptance criteria in writing within two business days | Approve the quote |
| Build | AI agents draft; a senior engineer reviews and tests; daily written updates in your repo | Answer questions, watch progress |
| Acceptance | You test against the criteria; anything that misses is fixed at our cost | Test and sign off |
| Handover | Documentation, deployment steps and a 30-day warranty | Deploy, or ask us to |
Sprint types
Which product development sprint fits your project?
Four sprint types cover most product development work. The quote tells you which one yours is.
| Sprint | Scope | Price | Duration |
|---|---|---|---|
| Fix Sprint | The top items from an audit or your own bug list | $3,000–$7,500 | 2–3 weeks |
| Feature Sprint | One well-defined feature or integration, end to end, with tests | $5,000–$12,000 | 2–4 weeks |
| MVP Sprint | A first releasable version of a product from a written spec and designs | $7,500–$15,000 | 3–6 weeks |
| White-label Sprint | Any of the above delivered under your agency's name, in your repo, for your client | Same, with agency terms | Same |

Should you choose fixed-price or hourly product development?
Fixed price suits work you can write down. Hourly suits work that changes every week. Here is how they differ.
| Factor | Fixed-price sprint | Hourly development |
|---|---|---|
| Price | Known before you start | Known after the work is done |
| Delivery date | Fixed in writing | An estimate |
| Scope changes | Quoted separately; the original price and date stand | Billed as they happen |
| Missed criteria | Fixed at our cost | Billed as more hours |
| After delivery | 30-day warranty on the delivered scope | Usually none |
| Best for | A written spec: features, fix lists, MVPs | An evolving backlog: see an embedded engineer |

How much do product development services cost?
Our product development services cost $3,000–$7,500 for a Fix Sprint, $5,000–$12,000 for a Feature Sprint and $7,500–$15,000 for an MVP Sprint. The price is fixed in writing before we start.
How long does it take to build an MVP?
An MVP Sprint takes 3–6 weeks from a written spec and designs, and costs $7,500–$15,000.
What counts as a written spec?
User stories or a feature list with acceptance criteria, plus designs or wireframes for anything with a UI. We'll tell you on the scoping call if it's enough.
What if the scope changes?
We quote the change separately. The original date and price stand unless you choose to swap scope.
Can we go hourly instead?
For sprints, no. If you want flexibility, an embedded engineer is the better fit.
Do you work white-label for agencies?
Yes. Specs come from your PM, we work in your repo and your Slack Connect channel, payment terms are with you, and volume agencies get a standing rate card and a reserved engineer.
Who owns the code?
You do. It is built in your repository from the first commit and handed over with documentation.
What happens after the warranty?
Quote the next sprint the same way, or keep a senior engineer on your team month to month.
How do I choose a product development company?
Look for a fixed price and date in writing, acceptance criteria agreed up front, senior review of every change and a warranty after handover.
