Production services

Production services for
AI-built software.

Q: Do you replace AI app builders like Lovable, Bolt, or v0?

No. Stackbilder complements them. AI builders get you to a demo fast. Stackbilder helps you harden that demo, add security analysis, document architecture decisions, generate test plans, and ship to production. These services are for the moment after the prototype works.

Q: What is an AI app hardening service?

It's a structured review and implementation process that adds security analysis (threat model), architecture documentation (ADRs), integration test specs, and deployment guardrails to AI-generated software. The output is actionable artifacts, not slide decks.

Q: Do you work specifically with Cloudflare Workers?

Yes. Stackbilder is purpose-built for Cloudflare-native systems using Workers, D1, KV, R2, Durable Objects, and edge-first deployment patterns. The buildout and governed workflow services are exclusively Cloudflare-native.

Q: What does the Security Trust Bundle include?

Seven signed security artifacts: threat model, CAIQ-Lite-style security questionnaire, incident response plan, security posture summary, data processing inventory, vendor security questionnaire responses, and a cryptographically signed trust receipt verifiable by any buyer at trust.stackbilder.com.

Q: Who are these services for?

Two groups. First: founders and operators of AI-generated or AI-assisted software who need to move from demo to production — agencies shipping client MVPs, security-conscious teams that need procurement artifacts, and lean Cloudflare Workers teams who need governed infrastructure without a platform team. Second: business owners in operations-heavy industries — professional services (law, accounting, consulting), trades (HVAC, plumbing, electrical, property management), hospitality, and healthcare — who want one specific workflow automated and a written report on whether it's worth building before committing to it. The audit tier is designed for this second group: you pick the process, we map it, you get a deliverable regardless of next steps. Business buyers who want operational due diligence before closing an acquisition also fall in this tier.

Q: Why is the audit scoped to just one process?

Because a full workflow evaluation requires you to share a lot of information with a stranger — and that's a high bar before any trust has been established. Starting with one process limits your exposure, gives you a concrete deliverable fast, and lets both parties figure out if working together makes sense. If you want to expand after the first report, we can scope that separately.

Q: Are you consultants?

No. We don't do advisory engagements, strategy decks, or recommendations you have to implement yourself. Every service produces a tangible artifact: a written assessment, deployed software, a governance suite, or a set of signed security artifacts. The output is something you own and can act on — not a slide deck.

Q: I'm evaluating a business acquisition — how does the assessment work?

You share what you can about the target company's internal operations — ideally a process walkthrough with someone on their team. We map the workflows, inventory the tech stack, and flag operational risks: key-person dependencies, manual processes that scale badly, hidden labor costs, and automation gaps you'd inherit. You get a written report before closing. Standard financial and legal due diligence doesn't cover this. We do.

AI tools can get you to a demo fast. Stackbilder helps you get from demo to something customers, security teams, and production traffic will not immediately destroy.

No slide-deck theater. Fixed-scope services. Real artifacts, running infrastructure, and production guardrails.

stackcloudflare/workers

Who we work with

Two kinds of clients. One standard of output.

technical teams

Founders, agencies, and engineering teams

You shipped something with AI tools and now it needs to be real. Security review pressure, procurement questionnaires, or a production incident waiting to happen — you need governance artifacts and a hardened build, not a strategy deck.

▸ AI-generated apps moving from prototype to production
▸ Agencies shipping client MVPs on Cloudflare Workers
▸ Security teams needing procurement artifacts fast
▸ Lean teams without a platform engineer on staff

operations-heavy businesses

Business owners with one process to fix

You run a real business — service firm, trade, clinic, property portfolio — and you have one workflow that is burning time or money. You don't need an IT department. You need a written assessment of what AI can actually do for that one process, and an honest call on whether it's worth building.

▸ Professional services: law, accounting, consulting, agencies
▸ Trades and field services: HVAC, plumbing, electrical, property management
▸ Healthcare and wellness practices
▸ Business buyers evaluating an acquisition target's operations

CTO · Decision Review

Engineering judgment when you need it.
Without the retainer.

Get a structured second opinion on architecture, hiring, vendor selection, and build-vs-buy calls before you burn budget in the wrong direction. Each consultation produces a confidence-scored recommendation — explicit, inspectable, and signed with a cryptographic receipt so the reasoning is auditable, not just plausible.

Structured, not speculative

The consultation produces a written recommendation with explicit stance, reasoning, and confidence score. You know exactly where to push back — uncertainty is surfaced, not buried.

Async, no scheduling friction

Submit your question. Get a structured recommendation. No 45-minute calls to schedule before you get an answer. Follow-up async if the recommendation raises new questions.

Cryptographic receipt

Every consultation ships with a receipt hash verifiable at verify.stackbilt.dev. The record is tamper-evident. What was recommended, and when, is preserved.

Security · Trust Bundle

Credible security posture.
Without the audit bill.

When a prospective customer's security team asks for your questionnaire, you need more than a self-attested spreadsheet. The Security Trust Bundle generates seven signed artifacts — threat model, CAIQ-Lite, incident response plan, security posture summary, and more — cryptographically bound so any buyer can verify authenticity at trust.stackbilder.com/your-slug.

Signed, not self-attested

Every claim — "universal MFA: enforced," "TLSv1.2+," "90-day log retention" — is bound into an HMAC-SHA256 signature. Edit one character and the signature breaks. You cannot quietly walk a claim back.

Verifiable by anyone

Your buyer's security team hits verify.stackbilt.dev/<hash> and recomputes the signature themselves. No login. No portal. No trust-me.

Regenerable when controls change

New subprocessor, tightened IR plan, rotated keys — re-run the bundle, sign a new receipt, publish to the same Trust Page. Prior receipts remain verifiable.

Built in the open

Proof we can build the stack we sell.

AEGIS is Stackbilder's internal autonomous operations system — built on the same architectural thesis behind every service we offer: deterministic structure surrounding probabilistic AI, with human approval gates at every meaningful decision point.

The AI reasons within bounded, auditable structure. Humans direct. The output is verifiable — not just plausible. No client case studies yet, so here's the system we run ourselves.

Common questions

Do you replace AI app builders like Lovable, Bolt, or v0?

No. Stackbilder complements them. AI builders get you to a demo fast. Stackbilder helps you harden that demo, add security analysis, document architecture decisions, generate test plans, and ship to production. These services are for the moment after the prototype works.

What is an AI app hardening service?

It's a structured review and implementation process that adds security analysis (threat model), architecture documentation (ADRs), integration test specs, and deployment guardrails to AI-generated software. The output is actionable artifacts, not slide decks.

Do you work specifically with Cloudflare Workers?

Yes. Stackbilder is purpose-built for Cloudflare-native systems using Workers, D1, KV, R2, Durable Objects, and edge-first deployment patterns. The buildout and governed workflow services are exclusively Cloudflare-native.

What does the Security Trust Bundle include?

Seven signed security artifacts: threat model, CAIQ-Lite-style security questionnaire, incident response plan, security posture summary, data processing inventory, vendor security questionnaire responses, and a cryptographically signed trust receipt verifiable by any buyer at trust.stackbilder.com.

Who are these services for?

Two groups. First: founders and operators of AI-generated or AI-assisted software who need to move from demo to production — agencies shipping client MVPs, security-conscious teams that need procurement artifacts, and lean Cloudflare Workers teams who need governed infrastructure without a platform team. Second: business owners in operations-heavy industries — professional services (law, accounting, consulting), trades (HVAC, plumbing, electrical, property management), hospitality, and healthcare — who want one specific workflow automated and a written report on whether it's worth building before committing to it. The audit tier is designed for this second group: you pick the process, we map it, you get a deliverable regardless of next steps. Business buyers who want operational due diligence before closing an acquisition also fall in this tier.

Why is the audit scoped to just one process?
