How I work.

No 90-page proposal. No agency team of ten. One builder, one anvil, four packages with clear pricing.

Pricing.

Starting prices are fixed-fee. Scope extensions are open and transparent. An agency of ten makes you pay the same for a team that has to switch tasks among themselves — we don't.

Why Foundry?

01

No agency overhead

No account manager, no sales team, no project-management layer. Direct contact between the builder and you.

02

Modern toolset, structural speed

Claude Code + Next.js + Vercel + Supabase. Same stack as Linear, Stripe, Notion. What an agency does in 8 weeks, we do in 2-3 — not a shortcut, just the right tools.

03

No hidden costs

Starting price is exactly what you get. Scope extensions are listed openly. You always know upfront what a choice costs.
