Engagement models
Pick the engagement that fits your build
Four ways to work with us. Each model is built around transparency, predictable delivery, and full IP ownership from day one.
- 01 / 04
Dedicated Development Team
Best for ongoing product delivery and long-term roadmap. A full team owned by you, working only on your product, reporting to your stakeholders.
- Best for
- Product companies, SaaS roadmaps, multi-quarter builds
- Billing
- Monthly retainer
- 02 / 04
Extended Team / Staff Augmentation
Plug specialists into your existing team. Senior developers slot directly into your sprint cadence, tools, and codebase with no friction.
- Best for
- Development teams needing surge capacity
- Billing
- Per-developer monthly
- 03 / 04
Fixed-Scope Milestone Build
Ideal when scope is stable and outcomes are clearly defined. Locked deliverables, locked timeline, milestone-based payments tied to demos.
- Best for
- MVPs, well-defined modules, fixed budgets
- Billing
- Per-milestone payments
- 04 / 04
CTO-led Architecture and Advisory
Modernization, performance audits, cloud strategy, and platform planning led by our CTO. Strategic input where it matters most.
- Best for
- Funded startups, legacy modernization, scale-up CTOs
- Billing
- Hourly or weekly advisory
Vendor comparison
Clear delivery, real ownership, scalable results
A delivery-first approach for U.S. teams who value clarity, security, and long-term reliability over short-term cost.
| Decision factor | Decipher Zone | Typical vendor |
|---|---|---|
| U.S. time zone overlap | Strong daily overlap | Limited or async only |
| Modern tech and AI stack | Deep, current, opinionated | Mixed, often outdated |
| Security-first delivery | Built-in from sprint 1 | Added later as patches |
| Delivery transparency | Weekly demos and milestones | Unclear progress, surprise slips |
| Long-term maintainability | Documented, tested, handover ready | Variable, vendor lock-in risk |
| Source code and IP ownership | Yours from day one | Often delayed or restricted |

How we work
Six steps from your first email to live software
Predictable, transparent, no salesperson in between. You talk to senior developers from the first call to the final launch.
- 01Day 0
Discovery call
A senior developer reads your brief and we hop on a 30-minute call. Goals, constraints, scope, time zone. No sales pitch, just questions and answers.
- 025 business days
Written proposal
You get scope, timeline, team shape, and price in writing. One page if simple, three pages if complex. No 40-slide pitch decks.
- 037 to 10 business days
SOW signed and team onboarded
NDA and IP transfer signed before any code is written. Developers join your Slack, Jira, GitHub. Source code lives in your repository from day one.
- 04Ongoing
Build in weekly sprints
Stand-ups twice a week. Working software every Friday. Transparent backlog so you see what is shipped, what is blocked, and what is next.
- 05Per milestone
QA gates and staged release
Automated test suites, accessibility audits, performance budgets, and security review at each milestone before the build ships to production.
- 06Post launch
Launch and continue
Most clients keep the same team for ongoing maintenance, performance tuning, and the next set of features. That is by design.
7-day no-risk trial on dedicated engagements
If the fit is wrong in the first week, cancel and pay nothing.

From the CTO
A note about the people you will actually work with.
Decipher Zone has been building software for USA clients since 2015. Ten years of shipping production code to companies like UnitedHealthcare, Indeed, Boston Beer, and Marra Forni has taught us one thing: clients do not want vendors, they want development partners.
That is why every project at Decipher Zone is led by a senior developer who has shipped the work before. No army of junior developers learning on your dime. No salesperson translating between you and the team. The person who reads your brief is the person who will lead your build.
If that sounds like the kind of partner you have been looking for, send a brief. Our CTO reviews every USA inquiry personally.
We deliver with US time-zone overlap, milestone clarity, and production-ready development, so teams move fast without delivery risk.
