What Arcade Does and Why It Matters

Arcade solves a critical gap in how enterprises authorize AI agents to access business applications.

›The company developed a platform that handles the authorization step of AI agent access, which defines what specific features an agent may use within an application
›Historically, developers had to build custom authorization mechanisms for each AI agent project, introducing time delays and cybersecurity vulnerabilities
›Arcade's prepackaged authorization features eliminate the need for custom code while reducing bugs associated with ad hoc security guardrails
›The platform proves that agents can perform specific actions on behalf of specific users on specific resources, addressing a core failure point in production AI systems

Series A Funding Round and Company Background

The funding announcement reflects strong investor confidence in Arcade's approach to agent security.

›SYN Ventures led the $60 million Series A round, with additional participation from Morgan Stanley and Wipro Ltd.
›The round follows a $12 million seed investment, bringing the company's total funding to $72 million
›Arcade was founded in 2024 by CEO Alex Salazar and CTO Sam Partee, both previously holding senior product roles at infrastructure companies Oka Inc. and Redis Inc.
›The new capital will be used to expand the platform's agent governance features and grow the company's MCP tool catalog

Technical Architecture and Security Design

Arcade's platform employs multiple layers of security to protect applications from unauthorized AI agent actions.

›The system uses OAuth 2.0, a widely adopted open-source protocol, to manage agent access through OAuth tokens that function similarly to passwords
›Tokens are encrypted before being sent to storage, not after, making it significantly more difficult for attackers to decipher credentials even if they gain access to the storage system
›The platform includes a salting mechanism that mitigates cybersecurity risks associated with credentials sharing identical plaintext values, a common vulnerability in poorly secured authorization systems
›Arcade integrates directly with companies' identity provider (IdP) systems, which track application access permissions, allowing automatic permission synchronization without manual updates

By narrowing the attack surface to authorize only specific agent actions, Arcade addresses a fundamental security weakness in current AI deployments. Traditional always-on authorization means that once a hacker compromises an AI agent, they gain unrestricted access to any application features the agent is permitted to use. Arcade's granular approach limits exposure by restricting agents to only the actions required for their specific tasks.

Limiting Attack Surface and Risk Reduction

One of Arcade's key innovations is recognizing and solving a widespread vulnerability in how AI agents are currently authorized.

›Most applications grant AI agents round-the-clock access permissions, meaning compromise of a single agent can expose entire application features to malicious actors
›Arcade's granular authorization approach restricts agents to perform only specific, predefined actions within applications
›The platform stores OAuth tokens securely using encryption before transmission, reducing the risk of credential theft
›Token management is handled by the platform rather than individual developers, eliminating inconsistent security implementations across different projects

This architectural difference represents a significant security advancement. When hackers gain access to an AI agent with round-the-clock access, they can compromise applications with relative ease. By contrast, Arcade's model ensures that even a fully compromised agent can only execute the specific authorized actions it was designed for, dramatically reducing the blast radius of any security incident.

Governance, Logging, and Operational Features

Beyond security, Arcade provides enterprise-grade governance and automation capabilities.

›The platform enables companies to log all actions performed by agents using Arcade's authorization system, providing full audit trails for compliance and investigation
›Over 8,000 MCP (Model Context Protocol) tools are available through the platform, allowing agents to automate a wide range of business tasks
›Agent permissions can be modified in real-time if a user's access rights change in the company's identity provider, ensuring consistency across all systems
›The governance features allow organizations to prove that each agent action is authorized for the specific user performing it on the specific resource being accessed

The Problem Arcade Solves in Production

According to CEO Alex Salazar, AI agent failures in production often stem from authorization issues rather than model quality.

›Production failures occur not because the AI model is wrong, but because organizations cannot prove that an agent is authorized to perform a specific action
›The authorization gap creates a compliance and security burden that slows AI adoption in enterprise environments
›Arcade's platform addresses this by creating a definitive, auditable record of what each agent can and cannot do
›This clarity enables organizations to deploy AI agents with confidence and maintain compliance with security policies and regulatory requirements

The statement from Salazar highlights a critical insight: the bottleneck in AI agent deployment is not model accuracy but governance infrastructure. Organizations need to be able to definitively answer the question: 'For this specific action, by this specific agent, on behalf of this specific user, on this specific resource, is this authorized?' Arcade's platform provides that definitive answer through its integration with identity systems and granular permission model.

Market Opportunity and Future Direction

Arcade is entering a rapidly expanding market for AI agent infrastructure as enterprises accelerate automation efforts.

›The AI agent authorization market remains largely unsolved, with most organizations still relying on custom-built solutions or inadequate off-the-shelf approaches
›As AI agents become more prevalent in business processes, the need for robust authorization frameworks will become critical to enterprise adoption
›The involvement of major investors like Morgan Stanley and Wipro signals confidence in Arcade's potential to become a category leader
›The company's roadmap includes expanding governance features and growing the ecosystem of available MCP tools, enabling agents to automate an increasingly broad range of business functions

Frequently Asked Questions

What is the difference between authentication and authorization in the context of AI agents?

Authentication verifies that an AI agent has permission to use a business application, while authorization defines which specific features within that application the agent can access. Arcade focuses on the authorization layer, determining what actions an agent can perform and on what resources.

How does Arcade's integration with identity providers work?

Arcade integrates with companies' identity provider (IdP) systems, which maintain records of user access permissions. When permissions change in the IdP, Arcade automatically updates the agent's authorization accordingly, eliminating the need for manual permission updates and ensuring consistency across systems.

Why is round-the-clock authorization a security risk for AI agents?

When agents are authorized with constant access to application features, a compromised agent can provide hackers with unrestricted access to those features. Arcade mitigates this by authorizing only specific agent actions, so even a compromised agent can only perform its authorized tasks.

What security mechanisms does Arcade use to protect OAuth tokens?

Arcade encrypts OAuth 2.0 tokens before they are sent to storage, rather than after, making them harder to decrypt if stolen. The platform also implements salting mechanisms to prevent attacks against credentials with identical plaintext values and handles token management centrally rather than requiring developers to build their own.

How many MCP tools are available on the Arcade platform?

Arcade provides access to over 8,000 MCP (Model Context Protocol) tools that AI agents can use to automate business tasks, with plans to expand this catalog further using the new funding.

As AI agents become more prevalent in business operations, platforms like Arcade that address the authorization and governance gap will be essential to enterprise adoption.
