Whatever you can describe,
we can ship in days.
Real code. Real output. Pick a snippet — watch it type out, then see what it would actually do in production.
Hardened on day one, not 'later'.
Typed everything, structured logging, error reporting, CI, deploy on push. No 'we'll harden it later'.
We meet your stack. We don't replace it.
Postgres, Redis, S3, BigQuery, Snowflake, Stripe, your queue, your cloud. We integrate; we don't force a rewrite.
Boring tech, on purpose.
TypeScript, Python, Postgres, Redis. The thing we ship in May 2026 still runs in May 2031.

FAQ
Things people ask before they buy.
Can you connect to my existing systems / databases?
+
Yes. The integration playbook covers Salesforce, HubSpot, Shopify, Stripe, QuickBooks, legacy SQL, internal REST APIs, brokerage APIs, and the long tail of badly-documented vendor APIs. If it has a way in, we'll find it.
Do you maintain what you build?
+
By default we ship and hand off. If you want ongoing iteration, the Embedded Engineer or Embedded Pod subscriptions are built for that — see /pricing.
Can you build trading algorithms?
+
Yes — that's a SKU. The trading-algo playbook covers equities, crypto, and options strategies with full backtesting, risk controls, and live broker integration. We are NOT a registered investment advisor; you own the strategy and the risk.
Will I get the source code?
+
Always. From day one, in your repo, under your account. Source code is yours — it's in the SKU.
Do you do AI / LLM apps?
+
Yes — RAG, agentic workflows, evals, fine-tuning. Built on the SDK directly, not on a leaky abstraction layer.

Audit, or straight to pricing. Either way, you talk to engineers — not a sales funnel.

What this means
A $19,995 MVP that ramps to $5,000/mo in 4 months with 8% monthly churn implies an average customer lifetime of 12.5 months. The MVP breaks even at month 7 and throws off ~$52,500 in the first 12 months.
