Full Web Teamfor Startups

Instead of hiring 5 engineers and managing them — get a full team that's already been through it.

A startup doesn't have three months for hiring. Doesn't have a senior salary to spend on a CTO who hasn't decided what to build yet. And doesn't have patience for VC philosophy about "keeping engineering in-house." What it has — a timeline. A budget. And users who are waiting.

We're your development team. Not an outside vendor — a partner. We come in as a complete dev team: an experienced CTO, full-stack engineers, a designer, and DevOps. You drive the vision. We build the product.

01 / Who it's for

Who this is for

We work with startups at every stage — from pre-seed to post-seed, with technical and non-technical founders alike.

  • 01
    Pre-Seed to Seed
    You have an idea. Maybe a first investor too. You need an MVP that works, fast, and professionally — so every funding round shows positive metrics.
  • 02
    Non-technical founders
    You understand the market, the customer, the deal. You don't have a CTO, and no time to learn Kubernetes. That's us.
  • 03
    Technical founders without a team
    You're the CTO. But you can't write all the code alone. A complete team that supports you and works to your standards.
  • 04
    Post-Seed startups
    That need fast team reinforcement. Instead of three months of hiring, you get a ready team in a week.
  • 05
    Companies launching a new product
    Without adding fixed headcount to the org. A team that works on the new product without interrupting the core.

02 / Track A · A defined MVP project

MVP development with a clear scope and a clear test goal

A first version built to answer one question with real users — not a small version of the full product. This is what gets delivered, what is included, and how you know the project is done.

What does the first version need to teach you?

Before scope comes a question: who the user is, what the problem is, and what they will do differently once the product exists. That hypothesis, one core flow and a now/later table are the input to the project. How to build them — in the guide:

How to define an MVP you can test with users — the full guide

What is delivered

  • An approved scope document
    The hypothesis, the user, the core flow, a now/later table with reasons, the metrics and the stop condition. This is the document the proposal is based on and that you approve before we start.
  • A designed interface for the core flow
    The core-flow screens in Figma, reviewed with you before code. Not every screen of the future product — only what is needed to complete the flow once.
  • A working version with real users
    An app or web system in a production environment, with the measurement defined in the scope document wired in. Every sprint — a version you can open and test, not a slide deck.
  • A handover package
    A repository in your name, cloud and store accounts in your ownership, operating documentation, and a list of what was built against the scope document — including what was deferred and why.

Scope and exclusions

An MVP project is defined by what is not in it as much as by what is. This is our default split — and it changes according to each project's scope document.

The last row is why there is no time commitment here without a scope document: the scope, not the label 'MVP', determines size and budget.
AreaInside the MVP projectOutside the project — separate agreement or on your side
SpecificationFocused specification of the core flow: entities, roles, states and the exceptions that must be handled in version oneA full product roadmap, market research, a business plan
DesignUX and UI for the core-flow screens, at a finish level suitable for real usersBranding, a marketing website, investor materials
DevelopmentFrontend, backend, basic permissions, the integrations without which the flow does not workNice-to-have integrations, a full admin panel, automations that serve future growth
Testing and releaseTesting of the core flow, a production environment, store submission when the deliverable is an appComprehensive test automation, load testing, compliance and security beyond the baseline
MeasurementWiring the metrics defined in the scope document, so the question the MVP was built for can be answeredAnalyzing the results and deciding what next — your decision, with the data in hand
After handoverHandoff and documentationMaintenance, ongoing development and day-to-day operations — on the ongoing-team track or under a maintenance agreement

Acceptance conditions — how we know we are done

  • The core flow completes end to end
    A real user, real data, in the production environment — not a developer's demo.
  • The metrics are being collected
    Every metric defined in the scope document is actually measured and can be read without asking a developer.
  • Ownership is yours
    Code, accounts, domain and stores in your name. No asset depends on an account of ours.
  • The documentation enables continuation
    Operating documentation, a list of what was built against the scope and what was deferred — so another team could continue from here.

And after the first version?

The decision is made on the feedback and usage that were measured — not on a feeling that one more feature is missing, and not as a promise of funding or adoption. Three continuations are possible: the next version as another defined project; moving to an ongoing team when the pace of change justifies standing capacity; or stopping with an orderly handover. Scope and budget for the continuation depend on integrations, risk and the infrastructure required — and are set again at each stage.

03 / What's in the team

What's in the team

A full team — not just developers. A CTO who leads, a designer who understands product, DevOps that handles infrastructure, and QA that tests it all. We plug in as one unit.

  • 01Tech leadership
    Experienced CTO / Tech Lead
    One person who owns the entire technical side. Makes decisions, designs architecture, enforces quality. Turns the idea into a technical plan.
  • 02Engineering
    Full-Stack engineers
    Working on both frontend and backend. We size the team to the need — from 1 engineer up to a team of 5+.
  • 03Product & design
    UI/UX designer
    Not a designer who only delivers pretty screens. A designer who understands product, UX, and works alongside the engineers.
  • 04Infrastructure
    DevOps / Cloud Engineer
    Handles infrastructure, deployment, cloud. So you never have to know what Kubernetes is.
  • 05Quality
    QA / testing
    Tests the product. Because a bug in production is a broken experience — and a customer who won't come back.
  • 06Product management
    Product Manager (optional)
    If you don't have someone running product, we can fill that role too. Prioritization, features, roadmap, measurement.

04 / Why not in-house

Why not build the team yourself?

Five reasons. Any one is enough on its own. Together — there's no debate.

The problemWhat it looks likeWith Onezero Labs
Cost & time of hiringHiring a senior engineer takes 2-3 months. Hiring a full team — half a year. Plus another 3-6 months until they ship.With us — one week.
SalariesA senior engineer in a major US market costs a six-figure salary plus benefits, equity and recruiting fees. A team of four is a seven-figure annual commitment before anything ships.With us — one monthly number that covers the whole team, no benefits or management overhead.
The team leavesIn an early-stage startup, turnover is high. An engineer leaving after 6 months — you go backwards.Us — we're not going anywhere.
Uneven workloadMost startups don't need 5 engineers all the time. Sometimes 2, sometimes 6.With us — flexible. We scale up and down with you.

05 / How it works

How it works in practice

  1. 01

    Week 1

    Kickoff & discovery

    Meetings with the founders. Understanding the product, the audience, the plan. An initial technical roadmap.

  2. 02

    Week 2

    Infrastructure setup

    Repository, CI/CD, environments (Dev/Staging/Prod), comms tools (Slack, Linear/Jira), process docs.

  3. 03

    Weeks 3-4

    First sprint

    We start building. Every sprint (two weeks) — a live build you can see.

  4. 04

    From day one

    Constant communication

    Dedicated Slack channel, weekly meetings, monthly reports. You always know what's happening.

  5. 05

    Throughout

    Right-sizing

    The team grows and shrinks with the need. You pay for what you need, no more.

What happens before week 1? You arrive with one hypothesis, one core flow and a now/later table — not a feature list. How to build that:

06 / Track B · An ongoing development team

An external development team to keep building the product

When there is a live product and a priority list that never ends, the question is not 'how many developers' but who is responsible for what, how priorities are set, and what happens at the start and at the end. This is the model.

When does an ongoing team fit?

  • A live product with users
    There is something to maintain and something to improve at the same time. A defined project does not suit work that changes direction every two weeks.
  • A steady pace of change
    User feedback, requests from business customers, regulatory changes. When the work list fills faster than projects close, you need capacity, not another quote.
  • Someone owns the product
    A founder, product manager or CTO who decides what matters. If there is none, we can fill the role, but the business decisions stay with you.

Which roles and how much capacity?

Capacity is described as roles and allocation type — not as a vague number of developers. The actual allocation is set in the agreement according to the workload, and changes with it.

No developer counts or FTE percentages here — they are set by the work at hand and written into the agreement, not into a marketing page.
RoleAllocation typeWhat it means in practice
Tech LeadStanding, part-timeOne point of contact. Owns architecture, code review and the two-week planning. The same person throughout the engagement
Full-stack engineersDedicated, sized to the workloadThe main allocation. Grows or shrinks with the work list, with the notice period set in the agreement
UI/UX designerAs neededJoins when there are new screens or an experience change; not on the team when there is no design work
DevOps / CloudSharedInfrastructure, deployments, monitoring and backups. Shared across clients, with defined responsibility for your system
QAPer sprintTesting of what each sprint delivers, and regression on the critical flows before every deployment
Product managementOptionalOnly if nobody fills the role on your side. Even then — the business decisions are yours

Who is responsible for what?

AreaYouUs
Product and prioritizationDecide what matters and why. Approve the sprint planPropose an order by effort and risk, flag dependencies, say when something is not worth it
ScopeDefine the business need and the acceptance condition for each itemBreak it into deliverable items, estimate, warn about overrun before it happens
DevelopmentAvailable for questions and decisions during the sprintCode, code review, documentation, unit tests. Code quality is our responsibility
QA and acceptanceTest against the acceptance conditions you defined. Approve releaseInternal testing and regression before anything reaches you for acceptance
Production and operationsOwn the accounts, the domain and the data. Decide on deployment windowsMonitoring, deployments, backups and incident handling — within the scope and service hours set in the agreement
BudgetSet the monthly capacity and the notice period for changing itReport capacity use every sprint; no overrun without approval

How is work planned and reported?

  • Two-week prioritization
    A short planning meeting: what goes into the sprint, what is deferred and why. The work list is one shared document — not message threads.
  • Delivery every sprint
    Every sprint ends in a version you can open, with a list of what went in. Whatever did not finish is said explicitly, not hidden.
  • Ongoing transparency
    A shared task board, a dedicated communication channel, and a periodic report: what was delivered, capacity used, open risks.
  • Changing direction mid-way
    Possible. The cost is the work already done on what gets deferred — and we state it before the change, not after.

How does it start, and how does it end?

  • Onboarding
    Access to code, environments and accounts; a review of the existing system and documentation; a list of known issues and risks; and the first acceptance conditions. If the product comes from a previous vendor, the full list of what to receive and check is in the takeover guide.
  • Offboarding
    A handover package identical to what we require when we take over a product: code in your name, accounts in your ownership, operating documentation, a list of open items and risks, and a handoff to the team that continues — in-house or external. The notice period is set in the agreement.

When is a defined project the better choice?

When the scope is known, there is a single target date and there is no live product to maintain yet, a defined project with written acceptance conditions gives both sides more certainty. The first version of a new product is almost always such a project; the MVP track above describes it.

07 / Beyond the code

  • Funding-round readiness
    Code that passes due diligence. Architecture that convinces investors. Reports that show what was built.
  • Network
    Designers, advisors, lawyers, accountants. We know good people, and we're happy to connect.
  • Perspective
    You're under pressure. We stop, check, give perspective. Like a real team.
