Real Impact, Real Results

Staff augmentation for teams who need engineering capacity now

01

Start in two weeks

No recruitment, interviewing, or onboarding cycle. We assemble your team and begin delivery within two weeks of signing.

02

Full team, not just a developer

Every engagement includes an engineer, a project manager, and a quality engineer. You get delivery management built in, not just coding hours.

03

Scale up or down on demand

Adjust team size as your needs change. No healthcare costs, no benefits, no layoffs. Expand when you are growing, compress when you need breathing room.

Staff augmentation done right

What a dedicated development team looks like in practice

If you hire a single engineer, you have to manage them, create tasks, and verify they are delivering. That is a lot of work, and we know this first hand. Every staff augmentation package includes three or four teammates working together so you do not have to manage the process yourself. Weekly allocation: 8h Engineer, 2h PM, 2h QE, 45 min Account Manager. We are still less than the lowest American agencies that charge $140 per hour.

Engineer

Your dedicated developer writes production code, participates in your standups, and works inside your existing systems. Matched to your stack, whether that is Python, React, Node.js, mobile, or something else. All our developers have been with NineTwoThree for over a year, and some for six years.

Project Manager

Responsible for estimating and delivering the project on time and on budget. Maintains the delivery boards, assigns tasks to the developer, and signs off on completion internally. Leads periodic client calls and keeps external and internal stakeholders informed about progress and challenges. Can also work inside your project board.

Quality Engineer

Tests every feature before it reaches you. Catches bugs, verifies edge cases, and ensures the code meets the requirements on the first pass so you get expected results without rework cycles.

Key Features

Transparent process, predictable cost, your time zone

Full transparency, every week

Know exactly where the project stands each week. You can monitor our project management boards directly. We hold periodic calls, define agendas, and keep you informed about progress and challenges.

Cost-effective, no hidden fees

A NineTwoThree retained team costs $1,200 per day (PM, Engineer, QE and expert advice included). A full-time hire costs $1,213 per day once you factor in salary, healthcare, FICA, 401k match, and equipment. You get a full team for less than the cost of one developer.

Flexible timezones

Our team adjusts to EST so all projects run the same cadence regardless of where the team resides. Core working hours sit between 8am and 3pm EST to support clients from California to Italy.

our process

How we onboard your dedicated development team

Connect With Our Leaders

Our process starts with connecting you to our leaders, who have built over 150 projects. If aligned, the second call includes our product managers and engineers to scope the work.

Rapid Validation and Proposal

Product managers and engineers review your requirements, identify the right team composition, and present a proposal with timeline and cost. No back-and-forth negotiation cycles.

Team Assembly and Kickoff

We assemble your dedicated team (engineer, PM, QE, and account manager) and begin delivery within two weeks of signing. The team integrates into your existing tools and workflows.

Build, Iterate, and Scale

Weekly demos, transparent boards, and periodic check-ins. Scale the team up or down as your needs change. Your account manager handles all adjustments so you can focus on the product.

FAQs

Find your answer in seconds

What is staff augmentation?

Staff augmentation is a cooperation model where an external agency's team integrates with your existing team to provide expertise you may not have in house. It is common in the IT industry for app development, machine learning, and cloud projects. The external team works alongside your team to accelerate delivery without the time and cost of hiring full-time employees. Learn more about how staff augmentation works.

Are your Product Managers based in the U.S.?

Yes. All of our product managers are based in the US and Certified. We only hire the best experts to support our clients.

How do you succeed with staff augmentation?

Treat the augmented team as part of your team, not as an external vendor. Share your business goals, product context, and success metrics. Assign a point of contact on your side who can make decisions quickly. Use shared project management tools so everyone has visibility into progress. Choose a partner that provides project management and quality engineering alongside development, not just raw coding hours.

When should you choose staff augmentation?

Choose staff augmentation when you need to deliver software fast and hiring is too slow. Common scenarios include building a new product without internal resources approved, needing specialized expertise (AI, ML, cloud) for a specific project, meeting a deadline that requires more capacity than your team can provide, or testing a new technology before committing to a full-time hire. See our staff augmentation startup launch checklist for a detailed guide.

What are the different types of staff augmentation?

The main types are: dedicated team (a full team assigned to your project for an extended period), project-based (team scoped to a specific deliverable), and skill-based (individual specialists added to fill a specific gap). NineTwoThree provides the dedicated team model with project management and quality engineering included.

What is the typical investment range for a dedicated development team?

Our retained team services start at $1,200 per day for a full team (engineer, project manager, quality engineer, and account manager). We can start within two weeks of signing. Contact us for a custom proposal based on your project scope and timeline.
