The best software engineering teams have invested relentlessly in their internal developer tools. Better tools meant developers could write more code, ship faster, and build better products. Historically, the frontier of developer tooling meant better IDEs, better compilers, better CI systems. Today, as software development shifts from human-written to agent-written, it means better infrastructure for coding agents.
Autonomous coding agents like Claude Code and Codex can now tackle hours-long engineering tasks with a level of capability that would have seemed impossible two years ago. Despite these incredible developments in coding capabilities, developers are resorting to walking around with their laptop cracked open to keep their agent running. Autonomous coding agents must run in the cloud in order to scale, creating a new bottleneck: the infrastructure around the agent. Coding agents need the runtime, context, and verification loop to scale in the cloud and turn generated code into ready-to-ship software. Niteshift is building exactly this: a cloud for coding agents that allows teams to run frontier and open-source coding agents inside fully configured dev environments.
Technology markets move in cycles of bundling and unbundling. AWS bundled compute, storage, networking, and databases into a single platform, but over time, the most sophisticated customers chose to unbundle — reaching for independent database companies, observability companies, and specialized tools for each layer of the stack. The market was large enough for both the bundled and unbundled players, but the best teams consistently chose best-of-breed. The same dynamic will play out in agentic coding. The first wave of products bundled the agent and the infrastructure together, locking customers into a single vendor at exactly the moment when prices skyrocket and the best coding agent changes every few months. Niteshift unbundles the infrastructure from the agent, so engineering teams can switch between frontier coding agents without rebuilding their own unique, complex dev environments.
A repo is not a runtime. Real applications depend on services like containers, databases, credentials, feature flags, background jobs, and data. Without its own infrastructure cloud, a coding agent can write code – but it cannot prove the checkout works, the chart renders, the bug is fixed, or the regression is gone. It can’t close the loop. And a coding agent that can’t close the loop doesn’t actually save you work; it just moves the work from writing code to validating code.
Closing the loop by giving agents a real environment to work in exacerbates the opportunity cost of the scaling pain. Once agents stop solving only quick tasks and start running for hours, developers begin running dozens in parallel to maximize productivity. That scale doesn’t fit on a laptop – even a $5,000 MacBook with 128GB of RAM quickly becomes a bottleneck. Cloud coding agents enable collaboration as well. AI expands the set of citizen developers, as product managers, designers, and operators all want to contribute. But dev environment setup is painful, and terminals aren’t designed for collaboration.
Sajid and Conor met at Datadog and shared an obsession with shipping fast. Conor was the number one committer in Datadog’s codebase, while Sajid led engineering teams that launched more than a dozen products during his time there. They spent the last decade developing expertise in building tools for cloud development, observability, and prod across complex codebases that they are now translating to agentic development.
We’ve been lucky to have worked through several platform shifts – the internet, cloud, mobile, and now AI – and the founders who succeed in these moments are rarely the ones chasing the wave at the surface. The best founders are the ones who see what the new capability demands underneath and start building for it before it’s obvious to everyone else. Sajid and Conor saw around the corner and recognized that agentic development was going to need a new kind of infrastructure company, and launched Niteshift to build that coding agent cloud.
We are excited to lead Nightshift’s seed round and we are joined in this round by Amplify, Box Group, and SV Angel.
