Founders post-launch who need to keep shipping without raising another round. SaaS companies with a roadmap growing faster than their engineering team can clear it. Product teams that need senior output without the 6-month hiring cycle. Non-technical founders who shipped an MVP and need an engine to scale it.

If you haven't launched anything yet, start with an MVP Build. If you don't know what needs to be built next, start with a scope call before a partnership. If you want hourly billing or a la carte work, this isn't it. If you can't move fast — our cadence is days, not quarters — we're not your team.

What does "embedded" actually mean?

Your Developer and QA join your Slack, your standups, and your weekly strategy calls. They work in your tools, your codebase, your conventions. They know your product like an in-house hire — because that's how they're set up to operate. Not a vendor sending status reports. A team placed inside your business.

What happens on the weekly strategy calls?

30 to 60 minutes each week with your dedicated team. We review what shipped, what's queued, what's blocked, and where the roadmap is heading. We bring our perspective — what we've seen work on other products, what's worth prioritising, where the technical risks are. You leave each call with clear next steps and a team that's already moving.

How is this different from hiring a senior developer?

A senior US developer runs $250K+/year base, $400K+ fully loaded with benefits, equity, tooling, and onboarding. You commit for years. You manage them. With OneChair Technical Partnership, you get senior Dev + QA + OneSpark + weekly strategy — starting at $192K/year, no hiring, no management overhead, with a 3-month minimum and no long-term lock-in.

Is the code AI-generated? Will it be a mess?

Every output runs through senior engineering oversight before reaching your repo. OneSpark handles velocity. Humans handle quality. The result is clean, typed, documented, production-ready code — the kind we ship on HIPAA-compliant healthcare platforms and financial software.

Why "starts at $16K"? What pushes it higher?

$16K covers an embedded Developer + QA pair on OneSpark with weekly strategy calls. If your roadmap needs more — additional engineers, design, infrastructure, larger ongoing capacity — we scope a higher tier. The scope call clarifies which tier fits.

Why flat fee? Why not hourly?

Hourly billing rewards slowness. We're optimised to ship — measuring hours undersells what OneSpark actually delivers. You pay for output and strategic partnership, not time spent.

What's the 3-month minimum about?

Software momentum compounds. Month one is ramp-up — your team learns your codebase and conventions. Month two is acceleration. Month three is when you see the gap between what you used to ship and what you now ship. Three months is the minimum window for the partnership to pay off.

What if my needs change month to month?

The partnership flexes. Heavy build month? Light maintenance month? Same flat fee, same team, different priorities. The weekly strategy calls keep us aligned to whatever's most important right now.

You do. Full repo access, full IP, full documentation. Always.

How does the 15-day paid trial work?

$16,000 for 15 days. We pick one release from your roadmap and ship it fully in 15 days — 100% requirements matched, guaranteed. If we miss any requirement, we fix it on our time. You experience the embedded team, the weekly strategy calls, and the OneSpark engine. If you continue into the partnership, the $16K trial fee counts as your first month — you've already paid for it. If you don't continue, you walk away with a finished release and zero further obligation.

The Problem

You shipped. Now what?

The Feature Backlog That Never Shrinks

Your roadmap has 40 items. Your team can ship 4 a quarter. Every week the backlog grows faster than you can clear it. The features that would unlock your next stage of growth keep slipping to "next quarter."

The Hiring Trap

You need senior engineers. A US senior dev runs $250K all-in. Recruiting takes six months. Onboarding takes three. By the time they ship their first feature, your runway is shorter and your competitors are further ahead.

The Agency Retainer That Doesn't Deliver

You're paying $20K–$40K a month for "dedicated resources" who shipped two features last quarter. The status calls are great. The output is not. You're locked in for twelve months and paying for headcount, not progress.

The Team That Burns Out

Your in-house engineers are buried in core product. Every new request adds to the queue. Morale drops. Quality drops. The features that should ship in days take weeks.

Stop paying for headcount. Pay for output.

The Partnership Difference

What changes when we're embedded.

Placed in Your Business. Not a Vendor on the Outside.

Your dedicated Developer + QA pair are embedded directly into your operation. Your Slack. Your standups. Your sprint planning. We meet weekly to align on strategy — what's shipping, what's next, what's blocked. We're not waiting on tickets. We're your development engine.

Month-to-Month After Month Three.

No long contracts. No exit fees. After your first three months, cancel any time with 30 days' notice. We earn the partnership every month, or you walk. That's the only commitment that matters.

Ship Continuously. Not in Quarters.

What takes a traditional in-house team six weeks ships in days. On WingmanAI we shipped a full frontend rebuild in 33 hours. WellChild — HIPAA-compliant — in 27. We will bring the same speed and execution to your team.

The Engine

OneSpark — The Engine Behind the Partnership

Your dedicated Dev + QA aren't working alone. They're orchestrating 85+ specialised AI agents running in parallel — scoping, building, testing simultaneously. Senior engineers verify every output before it reaches your repo. This is how a two-person team ships at the velocity of a seven-person one.

What's Included

Eight commitments. Every month.

Embedded In Your Business

Your team isn't a remote vendor. They're placed inside your operation — in your Slack, your standups, your sprint planning, your tools. They work to your conventions, your codebase, your team's rhythm. You won't notice they're not in-house.

Dedicated Developer

A senior engineer working only on your product. Not split across other clients. Not a junior under remote supervision. Yours, every day.

Dedicated QA Engineer

Every feature tested, every release verified, every regression caught before it hits production. Quality built into the workflow.

Weekly Strategy Calls

Every week, we sit down with you to plan what's shipping, what's next, and what's blocked. We're not waiting for you to assign tickets — we're helping shape the roadmap. Your development engine, not your task queue.

Dedicated Slack Channel

A shared Slack channel from day one. Daily updates, async questions, instant access. No tickets, no portals, no "let me check with the project manager."

OneSpark-Powered Velocity

Your team's output is multiplied by 85+ AI agents running under senior engineering oversight. The output of a 5-person traditional dev team.

Full Code Ownership

Every line of code is yours. Full repo access, full IP, full documentation. No vendor lock-in. Ever.

No Long-Term Lock-In

3-month minimum to get the partnership working. After that, month-to-month. Cancel any time with 30 days' notice — no exit fees, no negotiation. The partnership renews because it's working.

How It Works

STEP 01

Scope Call

30 minutes. You tell us what you've shipped and where you need to go next. We map the partnership shape — team size, priorities, cadence.

STEP 02

15-Day Paid Trial

Recommended first step. Before committing to a monthly engagement, run your first 15 days. One release, fully built, 100% requirements matched, guaranteed. The $16K trial fee counts as your first month if you continue.

STEP 03

Partnership Kickoff

We run a 2–4 hour deep dive on your roadmap, codebase, and priorities. Your dedicated Dev + QA pair are placed in your business. Slack channel opened. Staging URL live. Weekly strategy call scheduled.

STEP 04

Continuous Releases

You prioritise. We ship. Every release on staging from day one. Every release verified by QA before production. Your weekly strategy call keeps everyone aligned.

STEP 05

Monthly Review

End of each month, we review what shipped, what's queued, and what's next. The partnership flexes with your priorities. Renew because it's working — never because you're locked in.
