OneChair is an AI-orchestrated software development company. We use OneSpark, our proprietary system of 85+ specialized AI agents, to build production-quality software up to 97% faster than traditional development. Every project is overseen by a senior engineer who reviews, tests, and delivers the final product. We serve startups, small businesses, and mid-market companies who need enterprise-grade software without enterprise-level timelines or cost. See our custom software service and MVP development service for the specific types of projects we handle.
OneChair was co-founded by Jarrett and Anton. Jarrett leads business strategy and client relationships as CEO — he built OneChair around a single conviction: that clients should see working software within 48 hours, not wait months for a first look. Anton serves as CTO with 20+ years of enterprise IT experience, having built platforms from scratch for Fortune 1000 companies. Anton engineered OneSpark, the 85+ AI agent orchestration system that powers every OneChair build. Learn more on our about page.
OneChair is headquartered in Daytona Beach, Florida. We serve clients globally. All development is delivered remotely, with a live staging URL from day two so clients anywhere in the world can see and interact with their project as it is being built. We have worked with clients across the United States, Europe, and internationally.
OneChair was founded in 2024 and has delivered 7+ production projects across healthcare, B2B SaaS, real estate, and enterprise tools. Notable deliveries include WellChild, a HIPAA-compliant pediatric healthcare platform delivered in 27 hours, and WingmanAI, a full B2B sales intelligence SaaS delivered in 33 hours. We are a young company — and that is reflected in our rates and responsiveness relative to established agencies.
Three things set OneChair apart. First, parallel execution: OneSpark deploys 85+ AI agents simultaneously, so design, backend, frontend, testing, and documentation happen in parallel — not sequentially. Second, fixed pricing: we quote a single price before writing a line of code, and that number does not change. Third, live visibility: every client gets a staging URL from day two, where they can see and interact with real working software — not status reports. For a full comparison, see our AI agency vs traditional agency comparison.
AI-orchestrated development uses OneSpark, our system of 85+ specialized AI agents, to build software in parallel. Different agents handle different tasks simultaneously: database schema design, API contract definition, frontend component development, test writing, and documentation generation all run at the same time. A senior engineer sets the architectural direction, defines the technical requirements, and reviews every piece of output before it is delivered. The result is the speed of parallel AI execution with the judgment and quality control of professional engineering.
OneSpark is OneChair's proprietary AI orchestration system. It coordinates 85+ specialized AI agents, each focused on a specific domain: frontend development, backend API design, database schema, security review, test generation, documentation, deployment configuration, and more. OneSpark manages the dependencies between these agents, ensures their outputs are consistent with the overall architecture, and feeds the results to the senior engineer for review and delivery. It is the reason we can build production-quality software in days rather than months — and the reason our pricing can be fixed without absorbing unpredictable cost overruns.
We select the right tool for each project rather than defaulting to what is currently trending. Our most common stack: Next.js or React for frontend web, NestJS or FastAPI (Python) for backend APIs, PostgreSQL or Supabase for data storage, React Native for mobile, and Redis for caching. For infrastructure: Docker, AWS, and GCP. For payments: Stripe. We avoid exotic or immature frameworks in favour of proven technology with large hiring markets — so if you bring development in-house later, finding engineers who know the stack is straightforward.
AI agents generate the code, but a senior engineer directs the architecture, defines the technical constraints, and reviews every component before delivery. The process is analogous to a senior engineer directing a large team: the engineer does not write every line, but their judgment shapes every decision and their review catches problems before they reach production. No code ships without human review. Every project includes automated testing, and the final delivery includes a recorded walkthrough by the senior engineer explaining the architecture and key decisions.
Yes. Every project receives a live staging URL by the end of day two. You can log in, navigate the application, test features, and file feedback in real time — throughout the entire build, not just at the end. You watch the product take shape every day. This is one of the most significant practical differences between OneChair and traditional agencies: you see real working software, not status reports. The staging environment remains active throughout the project and during the post-launch support window.
Every project is quoted at a single fixed price before work begins. The price depends on scope, complexity, and compliance requirements. The best way to get an accurate number is to start with a free project audit — a 45-minute conversation where we review your requirements, ask detailed questions, and issue a written fixed-price quote. There is no commitment attached to the audit. If the scope is beyond what we can quote with confidence, we will tell you that too. Start the conversation here.
Hourly billing creates a structural misalignment between agency and client. The more hours logged, the more the agency earns — regardless of whether those hours produced value. Fixed pricing inverts this: we have every incentive to scope accurately, build efficiently, and avoid scope creep that benefits us but not you. When we quote a fixed price, we are accountable to that number. If the project turns out to be more complex than we estimated, we absorb the difference. Budget certainty is not a feature — it is the foundation of a fair engagement.
Yes. Most projects use milestone-based payment schedules: a portion upfront to begin work, a portion at key delivery milestones (such as when the staging environment is live and features are being reviewed), and the remainder on final delivery. The specific schedule is agreed in writing before work begins. We do not require full payment upfront, and we do not invoice beyond the fixed-price quote under any circumstances.
We are happy to discuss any project scope. In practice, the work we do best is production-quality MVPs and full custom platforms — not simple landing pages or minor modifications to existing systems. Most MVP projects start in the range of a few thousand dollars and scale from there based on complexity. The free project audit is the right place to determine whether the scope and budget are a good fit, with no commitment either way.
The fixed price includes everything needed to deliver a working production application: all source code, a private GitHub repository, deployment documentation, API documentation, a recorded senior engineer walkthrough, automated test coverage, and a post-launch support window. Hosting and third-party service costs (Stripe fees, cloud infrastructure, domain registration) are separate — we estimate these during the audit, but they are your ongoing costs, not ours.
Most MVPs complete in one to two weeks of build time. WellChild, a HIPAA-compliant pediatric healthcare booking platform with 116 screens, was delivered in 27 hours of active build time. WingmanAI, a full B2B SaaS with AI coaching, call recording, and CRM integration, took 33 hours. These are not outliers — parallel execution is the default. The total project timeline (including the audit, planning, and your review cycles) typically runs two to four weeks from first conversation to final delivery. See our MVP development service for more detail on what is typically included.
Three factors most commonly extend timelines: scope (more screens, more integrations, more complexity means more build time), compliance requirements (HIPAA, SOC 2, and similar frameworks require additional documentation, testing, and security controls), and feedback cycles (the faster you review and approve staging work, the faster we move). We build a realistic timeline into every quote so there are no surprises — and we flag any factors that could extend it during the audit conversation.
Yes. The free project audit produces a written, detailed estimate: project scope, timeline, fixed price, and any technical considerations or assumptions. The estimate is not a ballpark — it is the number we stand behind. If the audit reveals scope that makes a reliable estimate impossible, we will tell you what additional discovery is needed before we can quote with confidence. There is no cost to the audit and no commitment to proceed. Start the audit conversation here.
By the end of the second day of active development, every client receives a URL for a live staging environment. This is a real, working deployment of your application — not a mockup or a video demo. You can log in with test credentials, navigate the interface, test features as they are built, and file feedback in real time. The staging environment updates throughout the project, so you are watching your product take shape every day until final delivery. No waiting until week six to see something real.
Yes. Parallel execution is the default, not a premium option — which means we are inherently faster than sequential development regardless of urgency. If you have a hard deadline, tell us during the audit and we will structure the project plan around it. Most projects can be accelerated by narrowing scope for the initial delivery and adding features in a subsequent phase. We will give you an honest assessment of what is achievable in your timeframe during the audit conversation.
Yes, completely. All source code, assets, documentation, and infrastructure configurations transfer to you at delivery. We provide a private GitHub repository in your account, not ours. There are no licence fees, no lock-in clauses, no restrictions on how you use, modify, or redistribute the codebase. You own it in the same way you would own code written by an employee — outright, without conditions. This applies to every project, including MVPs and technical partnership engagements.
Yes. We offer monthly retainer partnerships for clients who want ongoing feature development, maintenance, and technical support after their initial project delivers. Retainers are scoped based on your expected monthly workload. There is no requirement to use a retainer — some clients take delivery, hand the codebase to their own team, and never need us again. Others use us as an ongoing technical partner for years. Both outcomes are valid. See our technical partnership service for details on how ongoing retainers work.
Every delivery includes: full codebase documentation (module descriptions, component APIs, data model documentation), API documentation (all endpoints, request and response schemas, authentication flows), deployment documentation (environment setup, configuration variables, deployment instructions for each environment), and a recorded senior engineer walkthrough explaining the architecture and key decisions. Documentation is generated and reviewed during the build — not written as an afterthought at the end. When you hand the codebase to another team, they have everything they need.
Yes, and we actively support this transition. We use standard, well-documented technology stacks (Next.js, NestJS, PostgreSQL, React Native) with large engineer hiring markets. The complete codebase, documentation, and architecture decisions transfer to you at delivery. If you want to hire engineers to maintain and extend the product, we can provide technical briefings for new team members and answer questions during the transition period. We are never the reason you cannot move on — being easy to hand off is part of how we define a successful delivery.
Post-launch changes are handled either through a monthly retainer or as standalone one-off projects, depending on scope. Small changes — bug fixes, content updates, minor feature tweaks — are typically covered under the post-launch support window included in every delivery. Larger additions (new features, integrations, or platform extensions) are quoted as fixed-price projects following the same audit process. You will never receive an unexpected invoice. Get in touch to discuss what your post-launch needs look like.
