05 / Why Foundry

Plan with confidence

Every plan is reviewed for gaps before you see it. What reaches your team is build‑ready — not a draft.

Keep every team aligned

One shared plan for engineering, product, and IT. Everyone sees the same scope, owners, and dates.

Stay in control

Access, budgets, and audit are built in from day one. You decide who sees what — and what it costs.

06 / How it works

Tell it what you’re building

Write a few sentences — or attach the RFC. Foundry asks about the constraints that matter: scale, compliance, timelines, and the systems you already run.

1.0Describe your project

New plan · Draft 01Jul 24, 2026 · 14:12

We’re replacing our on‑prem billing system with a multi‑tenant cloud service. 40k merchants, PCI scope, zero‑downtime cutover from the PHP monolith.

Repo · meridian/billing‑coreDoc · RFC‑118 cutover constraintsGenerate plan

Get a plan you can challenge

Foundry drafts phases, tasks, owners, and estimates — then reviews its own work for gaps. Approve it, or push back line by line. Nothing ships until you sign off.

Approved plans sync to VS Code as tasks with full context attached. Progress flows back automatically, so the plan stays true while you build.

Manage

Progress rolls up from commits to phases — status reports write themselves.

Migrate

Legacy systems get a mapped, staged path — no big‑bang cutovers.

Security

Every plan ships with a security review — gaps found and fixed before build.

08 / Enterprise

Built for companies that can’t afford surprises.

You decide who sees what

Roles and access map to how your org already works. Provision through your identity provider — nothing lives outside it.

Every action is on the record

Plans, reviews, and exports are logged as they happen. Your security team can watch the stream — not request it.

Spending never surprises you

10 / FAQ

What teams askbefore they start.

Your project data stays inside your workspace, and it is deleted when you delete it.

In managed cloud storage, in the regions you choose. Enterprise plans can pin data to specific jurisdictions.

Plans arrive as tasks in VS Code through our extension. Your team keeps its repos, branches, and review process — Foundry works around them.

Yes. Set budgets and quotas per team or per project; Foundry stops before a limit is crossed, not after. Usage is visible in real time.

You keep everything and add limits, not migrations. Enterprise adds custom capacity, SLAs, and data residency on top of the same workspace.

We answer standard questionnaires and share our security documentation on request. Most reviews clear in days, not months.
