The short answer
Choose an agency when the project needs people: complex integrations, regulated data, a large or unusual system, or someone in the room taking responsibility for judgment calls. Consider a coordinated team of AI agents, such as 19 Agents, when you want a new website, a small web app or the first version of a product, want to know the price before anything starts, and are happy to make the business decisions yourself.
Side by side
| Question | A software agency | 19 Agents |
|---|---|---|
| Who does the work | People: project managers, designers, engineers. | AI agents with separate roles, coordinated for you. The founders read beta requests themselves. |
| How the price is set | A fixed bid or billed time, depending on the agency and the contract. | One fixed price for the accepted scope, approved by you before the work starts. |
| If it takes longer | Depends on the contract: on billed time, you usually pay for it. | The approved price does not change. The delivery date is a forecast. |
| Changes | Change requests, priced by the agency. | A new quote for the new scope, which you approve before anything changes. |
| Quality checks | The agency's own review and testing process. | Separate agents review and test, and every stage is recorded as evidence. You review the release. |
| Who owns the code | Set by the contract; ask before you sign. | You do, and you can push it to your own GitHub repositories or ask for an export. |
| What it can build | Almost anything, given enough time and budget. | Websites, small web apps and first versions of products. Not every application type yet. |
Where an agency is the better choice
- Your product handles real customers' personal data or money from day one.
- It has to connect to systems the beta does not offer, or to code you already have.
- You want people who will take decisions for you, not only ask you for them.
- You need meetings, workshops and a named person accountable for the project.
Those are real strengths, and 19 Agents does not pretend to replace them.
Where AI agents make sense
- You have a clear idea and no engineering team, and you would rather not manage one.
- You want to know the price before anything starts, and want it to stay that price.
- You want to see what was built, reviewed and tested, not only hear that it was.
- You want to keep making the business decisions: the scope, the price and the release are yours.
19 Agents automates and coordinates a substantial part of software delivery, from planning to release. Some decisions and interventions still need you, and a blocker the agents cannot resolve is escalated to you.
The beta, plainly
- The beta is closed, and admission is gradual. It is not offered in the United Kingdom.
- Every product starts from a new idea. Bringing code you already have comes after the beta.
- The beta is for building and testing: it does not include collecting personal data about real customers or users, or connecting a production database.
- Not every type of application or business requirement is supported yet.
The beta does not charge you money; the terms are shared on admission. The beta page explains who it is for and how admission works.
Questions
- Are AI agents cheaper than a software agency?
- For the kind of project 19 Agents takes on, you can compare directly: you see one fixed price for the accepted scope before any work starts. For large, complex or regulated projects an agency may be the only realistic option, whatever the price.
- Is the code written by AI agents any good?
- Separate agents review the code and test it, and every piece of work carries its recorded evidence. No software is free of defects and passing automated checks is not a guarantee, so by default you review the release before it goes live.
- Can I switch from 19 Agents to an agency later?
- Yes. The code is yours: you can push it to your own GitHub repositories, and you can ask for an export of your code and project materials, which any developer or agency can pick up.
