Suborbital
Suborbital is a private Ottawa-based company (founded 2020) that historically built cloud-native WebAssembly web services on its Atmo platform for developers needing safe third-party code execution; the firm raised a $1.6M seed from Amplify Partners in 2021, but its primary web property now operates as an unrelated personal blog.

What Suborbital does
Suborbital is a private Canadian company founded in 2020 and headquartered in Ottawa, with stated headcount of 11-50 employees. According to firmographic data, the company positioned itself as a cloud-native WebAssembly platform — building web services on top of an underlying technology called Atmo — targeting software developers, architects, and engineering teams who need to safely execute third-party or user-provided code within extensible SaaS applications. Core technical coverage historically included sandboxing architectures, gRPC plugin interfaces, RBAC and Zero Trust execution models, and integration with runtimes such as Deno, QuickJS, V8, WasmEdge, and Wasmtime.
The company closed a $1,600,000 seed round led by Amplify Partners on 2021-11-23, the only disclosed institutional financing in the record. Named leadership comprises Connor Hicks (Founder & CEO) and Dan Callahan (Director of Developer Experience). No commercial product, pricing model, paying customers, or ARR figures are disclosed; pricing details indicate the entity operates as a content publication with a newsletter subscription model rather than a transactional software business.
A material contradiction exists between the firm's stated WebAssembly/enterprise-developer positioning and the current state of its primary web property. The suborbital.dev domain now resolves to "OrbitalSD," a personal technical blog authored by William Vaughn whose most recent posts (dated 2026-05-08) cover online casino deposit experiences (Tropicanza) and consumer mobile app design (SlotsDJ), rather than the previously documented sandboxing, WebAssembly, or serverless topics. This repurposing, combined with the absence of any post-2021 funding, product, or hiring signals, raises fundamental questions about the continuity of Suborbital's original platform operations and should be diligenced carefully.

Suborbital product offering
Product offeringCore offering
Suborbital develops Atmo, a cloud-native WebAssembly-based platform for building and running web services. Atmo enables developers to execute application logic in isolated, sandboxed environments using WebAssembly, supporting secure plugin architectures, custom user code, and extensible SaaS platforms. The company also publishes engineering guidance through its OrbitalSD technical blog.
Product overview
OrbitalSD is a technical blog/educational resource operated by Suborbital. It is not a product company; the site publishes articles, guides, and technical analyses about frameworks, runtime systems, and technologies for running third-party code securely (such as WebAssembly, Docker, gRPC, sandboxing, and serverless architectures). There are no commercial products, modules, or paid offerings.

Suborbital competitors and assessment
Company assessmentDirect peers
- Fermyon: Fermyon builds a cloud-native WebAssembly platform (Spin) for serverless microservices. It is the most direct competitor to what Suborbital set out to build with Atmo, targeting developers building extensible applications with Wasm runtimes.
- Wasmer: Wasmer provides a WebAssembly runtime and edge platform for executing Wasm modules. It is directly comparable to Suborbital's Atmo-based vision of running WebAssembly in cloud-native environments.
- Cosmonic: Cosmonic offers a WebAssembly-based application platform built on wasmCloud, competing directly with Atmo-style cloud-native Wasm runtimes for distributed application development.
- Deno: Deno is a secure-by-default JavaScript/TypeScript and WebAssembly runtime frequently covered in OrbitalSD's content. It targets developers building extensible serverless applications, overlapping with Suborbital's secure code execution focus.
Broad incumbents
- Cloudflare Workers: Cloudflare Workers provides a globally distributed serverless runtime that supports WebAssembly modules. As a much larger incumbent, it competes in the cloud-native Wasm execution space where Suborbital originally aimed to operate.
- Fastly Compute: Fastly's Compute@Edge platform supports WebAssembly for edge functions, competing with cloud-native Wasm application platforms like the one Suborbital envisioned with Atmo.
Emerging players
- Vercel: Vercel provides edge functions and a deployment platform for modern web frameworks, overlapping with Suborbital's stated mission of creating web services in a new way via cloud-native technologies.
- Modal Labs: Modal provides a serverless platform for running compute workloads including custom code execution. It addresses the same secure third-party code execution problem space that OrbitalSD's content covers.
- Trigger.dev: Trigger.dev is a developer platform for background jobs and workflows, frequently referenced in OrbitalSD's framework comparison content. It represents an adjacent product in the secure code execution and extensibility category.
Others
- Bytecode Alliance: The Bytecode Alliance is an industry consortium advancing WebAssembly standards and runtimes (Wasmtime, WasmEdge). It is thematically related to Suborbital's Wasm focus but serves as an enabling ecosystem organization rather than a commercial competitor.
