CLAUSE I
Subcontracting
You never learn who actually built it

Work gets subcontracted again and again, and nobody knows who built it

We never subcontract a project we have taken on without the client knowing. When we do need a resource we don't have in-house, we say so openly, name the external partner, and keep the process visible from end to end.

CLAUSE II
Walking away
Unreachable, slow to respond

The vendor disappears halfway through, and replies take weeks

We have inherited many projects where the previous vendor walked away, the engineer resigned with no handover, or the work stalled because the fee was too low — and even when they could be reached, a reply took a week or two. Every JoinX project has a named owner, with an account manager and a project lead behind them.

CLAUSE III
Schedule
Launch keeps slipping

The timeline slips and slips, and launch never arrives

Within the scope agreed in the contract, we commit to completing the work inside the contract period. A schedule that keeps slipping doesn't just delay a project, it derails the business plan behind it. Our goal is the same as yours: getting the system live.

CLAUSE IV
Code ownership
Your build resold to someone else

Your build gets resold, and you never owned the code

We don't compete with our clients. We focus on B2B services — helping clients build their own business models. We learn the domain, but we have no interest in productising or reselling what we build for you. Source code is priced as a full buy-out by default. We only do well when our clients do well.

CLAUSE V
Handover
Blocked from taking it in-house

You want to bring it in-house later, and the vendor won't cooperate

Whether you take it in-house, hand it to a friend, or move it to another vendor, we honour whatever the contract says. We are a services company: we deliver the scope we accepted, we cooperate with your future plans as far as we can, and we will not be the obstacle.

CLAUSE VI
Team seniority
All juniors, no experienced staff

It's all juniors, with no experienced people on the team

We have many young engineers, but none of them are blank slates. Anyone who joins JoinX — junior included — clears a high technical bar, and our technical leads are experienced developers in their fields who review work at every layer. We care a great deal about what we ship.

2026 ADDITIONAL CLAUSES

In three years, clients started asking different questions

The original six answered one question: will I get burned? What clients ask most now is about AI, data, and whether they really get everything at the end. These three are commitments we hold to just the same.

CLAUSE VII

Whether AI is used, and where

Unreviewed AI code; your data used for training

Before we start, we tell you which parts of the build use AI tooling. Everything it produces is reviewed line by line by our engineers, and we remain accountable for it. Without your written consent, we never send your source code, data, or commercial documents to a third-party AI service that trains on them.

CLAUSE VIII

Where your data lives, and who can reach it

Scattered access that outlives the people who had it

Project data sits in your accounts and your cloud environment. We take only the access we need, and revoke it the day a team member moves off. We work to ISO 27001:2022 processes and leave no undisclosed back door or remote access in your systems.

CLAUSE IX

Whether everything really gets handed over

Accounts and domains held as renewal leverage

At closeout we hand over the source code, deployment documentation, environment configuration, and every account and domain we registered on your behalf — in one go. We never hold an account, domain, or server as a condition of renewal.
