The built4agents journey

How it works

Discover products agents can use to get things done. Present your own SaaS, service or tool and show the community what it makes possible.

What belongs on built4agents?

Products for the work agents do.

An agent-ready product gives an AI agent a documented way to accomplish a task or access a useful resource. It can serve human users too.

SaaS & business services

Manage customer work, book appointments, create content or handle business operations.

Tools & infrastructure

Search, data, memory, browsers and computing environments that give agents the resources to work.

Control & verification

Check real state, respect permissions, track results and recover from failures.

Specialist agents

Agents that other agents can call or delegate a documented task to.

API, MCP, A2A, CLI, SDK or another documented access method: explain the work an agent can do first, then how it connects.

People set the goal. Agents use products to act.

We believe more of our work will be carried out by AI agents using software on our behalf. A person defines the goal and permissions; agents use services to carry it out, with results that can be checked in the systems where the work happens.

Human intent → AI agent → agent-ready product → verifiable result

For example: ask an agent to arrange a meeting. It can check availability, book a slot with permission and retrieve the booking confirmation. This is an illustration of the work these products enable.

Discover a capability. Introduce your product.

Explore products by task and access method, read their documentation and ask questions in the discussion. If you build one, submit it for a lasting listing or a weekly launch. Both are free and reviewed before publication.

What a listing gives you →
01 / SUBMIT

Start with the product

Makers choose a directory listing or a weekly launch. Members can also suggest products they have discovered.

02 / REVIEW

Check the fit

Reviewers check agent use, documentation and duplicates before a listing or launch goes live.

03 / LAUNCH

Choose a launch week

Listings can publish after review. Optional launches begin on a confirmed Saturday at 10:00 London time, with seven days of voting.

04 / VOTE

One vote, one voice

Eligible members can support each launch once. Equal vote counts share the same rank.

05 / DISCOVER

Built to be found later

After voting closes, the product page and discussion remain in the directory. Meaningful updates can earn another reviewed launch.

The details

Clear rules for every launch.

The visual path is a quick guide. These are the rules behind it.

01

Launch together

New launches start every Saturday at 10:00 London time. Each launch receives seven days of voting, then stays in the directory.

02

A simple ranking

One eligible account, one vote per launch. Owners can vote for their own products, with the same weight as any member. No votes or points are added automatically. Equal vote counts share the same rank. Comments and outbound clicks do not add points.

03

Refreshing results

Scores update after your vote. Use Refresh ranking to update the order of the list. Rows stay in place while you vote.

04

Support, not a review

A vote supports a product you find useful. It is not a verified review, certification or guarantee.

05

Anyone can suggest

Members can suggest a product with a documented agent capability for the directory. Its maker can later claim the listing and request a launch.

06

Built for agent use

SaaS, services, tools and infrastructure need a concrete, documented capability for agents. A generic API or an AI-ready label alone is not enough.

07

After launch

The product page and discussion stay available. A major new agent capability may launch again after at least eight weeks and another review.

About review

Reviewed for scope, not certified.

Listings are reviewed for scope and consistency with their public documentation. Product performance and security are not certified. Changing ownership preserves existing votes. Closed results can change after moderation or account deletion.

Does my product belong here?

Can I submit an existing SaaS?

Yes, if it offers a concrete, documented capability for agents. Products built for agents from day one and existing services adapted for agent use can both belong here.

Does my product need to contain AI?

No. A booking service, database or payment tool can give an agent a useful capability without running an AI model itself.

Can it also have a human interface?

Yes. People may use a dashboard to configure the service, approve actions or work alongside agents.

Is having an API enough?

An API alone does not establish fit. Show the specific capability offered to agents and link to documentation explaining how they can use it.

Do you only list MCP servers?

No. MCP is one access method. Products using APIs, A2A, CLIs, SDKs and other documented access methods are welcome.

Can an agent itself be listed?

Yes, if it provides a documented service another agent can use or delegate work to. Explain the task it accepts and the result it returns.

Can I list without launching?

Yes. Choose a directory listing to publish after approval. You can request your initial launch later on the same product page. With a weekly launch, your approved listing is available in advance and voting opens on the confirmed date.

Can I suggest a product I do not own?

Yes. Use the suggestion path and identify the product accurately. A suggestion does not give you ownership or authorize you to launch on the maker’s behalf.
