dev/agents

/dev/agents (website sdsa.ai) is a San Francisco-based company building what it describes as a next-generation, cloud-based operating system for AI agents. The stated premise is that agentic applications will change how people use software day to day, but that this shift requires new user interface patterns, a reimagined privacy model, and a developer platform that makes it practical to build robust consumer experiences and more capable applications.

According to Sacra, the platform is intended to coordinate autonomous AI agents across all of a user's devices, functioning for agents in the way a conventional operating system functions for apps. A task such as planning a trip would be decomposed across multiple specialized agents — for example one searching flights, another booking accommodation, another suggesting activities — coordinated through a central layer. The architecture is described as maintaining a shared model of each user's preferences, history and tasks that is accessible to all agents, so context does not have to be restated. The system is described as running across laptop, phone and voice contexts as one continuous interaction, generating context-appropriate interfaces (for example a calendar view for dates or a map for excursions) using generative AI.

CEO David Singleton has framed the problem as one of developer tooling: building an AI demo is fast, but producing something consumers will trust with a credit card is difficult, and developers lack standard tools and systems on which to build agents. The company compares its ambition to Android's role in making mobile development broadly accessible.

Founding story

The company was founded by four executives with backgrounds in Android and other platform work: David Singleton (co-founder and CEO), previously CTO of Stripe and before that a Google engineering leader for Android, including Android Wear; Hugo Barra (chief product officer), formerly VP of product management for Android at Google and head of Meta's Oculus VR division; Ficus Kirkpatrick (CTO), an early Android engineer and former VP of AR/VR at Meta; and Nicholas Jitkoff (chief design officer), formerly a principal designer on Google Chrome/Chrome OS with senior roles at Dropbox and Figma. Singleton has said the motivation mirrors the pre-Android mobile era: the promise of the technology was visible, but it was too hard for developers to build good products on it. Startup Intros states the name was inspired by early Stripe's "/dev/payments" naming.

Business model

Sacra describes /dev/agents as a platform business with a B2B2C go-to-market approach, serving both developers who build agent-based applications and the end users who interact with those agents, analogous to how Android created value for device makers and app developers. Its cost structure is described as dominated by R&D and cloud computing infrastructure, particularly AI inference compute for continuously running agents.

Singleton has indicated monetization would resemble how Android is monetized: taking a cut of commerce transacted through the platform, and/or charging users subscriptions. Sacra similarly identifies two mechanisms — transaction fees, where the company takes a percentage commission on agent-completed purchases such as flights or products, and subscriptions — tying revenue to economic value flowing through the platform rather than charging for the technology directly.

Traction

Documented traction is limited to financing and team. The company raised a $56 million seed round in November 2024 at a $500 million post-money valuation while pre-product, backed by Index Ventures, CapitalG, Conviction and a set of angels including Andrej Karpathy, Alexandr Wang, Andy Rubin, Nikesh Arora, Dave Burke, Soleio Cuervo, Claire Hughes Johnson and Shishir Mehrotra. Startup Intros reports a team size of 1-10 employees and one funding round to date. No users, revenue or shipped product are reported in the sources.

Latest developments

The most recent development documented in the sources is the November 2024 seed financing and the accompanying public launch of the company's positioning. At that time, /dev/agents said it expected the first version of its product to be available by early-to-mid the following year. Sacra's profile, dated 2025, still lists $56 million in total funding and a $500 million valuation, indicating no subsequent round is reported. A CapitalG portfolio page describes a company called Dreamer (dreamer.ai) using near-identical language and listing David Singleton as co-founder and CEO with an initial investment in 2024; the sources do not explain the relationship between the two names.
