What Zenveus does
One engineering partner for three product moments.
Audit what exists. Fix what matters. Build what comes next. Stay when the roadmap keeps moving.
01
Audit, fix and harden
Applications built with Lovable, Bolt, Replit, Supabase, Cursor and Claude Code—reviewed for the risks a working demo does not reveal.
02
Build to a published standard
Nine checks with pass thresholds covering security, data isolation, payment integrity, scalability, testing and observability.
03
Add senior capacity that stays
Embedded engineering pods for teams that need ongoing delivery without repeatedly onboarding a new team.

Lane 01 · Fix it
We've read this codebase before.
Different founder, different tool, the same handful of problems. Here is what we find almost every time.
S-01 · Critical
Anyone can become an admin
The role gets set by the signup form and trusted by the server. Change one word in the request and you have administrator access.
S-02 · Critical
Users can see each other's data
Row-level security half-wired or never switched on. The interface only shows your rows. The API returns everyone's.
S-03 · High
Works in preview, 500s in production
Environment variables, build config, or both. Fine in the builder, dead on the real domain, and the error tells you nothing.
S-04 · High
Payments look fine and aren't
Checkout half-finished, webhooks failing silently, retries double-charging. You find out from a customer.
S-05 · High
Falls over past a hundred users
Queries inside loops, no caching, no indexes. Fine at ten people. Unusable at a hundred, which is roughly when it starts mattering.
S-06 · Medium
Nobody can read it
No structure, no types, no docs. The next developer needs weeks before they can change anything safely, and you pay for those weeks.
These are recurring failure patterns, not a claim about your product. Run the relevant check and treat anything without evidence as unknown.
Evidence-based, read-only first pass.
The Standard
Production-ready, defined.
Nobody had written down what production-ready means for AI-built software. So we did.
Version 1.0 publishes the evidence states, weights, thresholds and critical-finding cap behind every score.

Where we go deepest
Regulated data changes the standard.
The same engineering mistakes cost more when the product carries health, financial, legal or policy data. These are the systems we know best.
InsurTech
Carrier and rating-engine integrations, nested broker permissions, policy and filing data handling, agency-system reconciliation, claims-workflow correctness.
- 09:14Record created
- 09:18Clinician reviewed
- 09:23EMR handoff
Healthcare
HIPAA-aligned data handling, PHI-safe logging, audit trails that survive a review, and EMR handoff integrity.
Lane 02 · Build it right
Built right the first time costs less than hardened later.
Most of what we fix in lane 1 was avoidable. The same senior review that rescues a broken app is cheaper applied before the code exists.
New products
Scoping to production, fixed scope, weekly demos, meeting the Standard the day it ships.
AI into a live product
Agents, retrieval and automation added to something already carrying users, without destabilising it.
The rebuild call
Sometimes the honest answer is rebuild the core, keep the rest. You get that in writing before committing.
Architecture decision review
Describe the outcome, critical workflow, constraints, and decisions that will be expensive to reverse. Start with the diligence assessment; add senior review when the evidence needs interpretation.
Lane 03 · Keep shipping
A team that already knows your codebase.
Not a rotating bench, not a staffing contract. A small senior-led group who learn your product once and keep shipping against your roadmap, with QA and a lead engineer included.
What is included
Engineers, QA, a lead engineer signing off, and a founder attached to the account. Scale up or down monthly.
What it replaces
The senior hire you have been trying to make for six months, without the search, the equity, or one person leaving with all the context.
Free: hire versus pod calculator
Salary is roughly two thirds of what a senior engineer actually costs. This works out the rest and compares it honestly. If the hire is cheaper for you, it says so.
How we work
We build with AI. A senior engineer signs off on every line.
Most teams do one or the other: fast and messy, or slow and careful.
function canAccess(record, user) {\n- return record.userId === user.id;\n+ return policy.canRead(user, record.tenantId);\n+ // covered by tenant-isolation.spec.ts\n}01 — DRAFT
AI writes the first pass.
Fast, and never the version that ships.
02 — REVIEW
A senior engineer reads it.
They rewrite what needs rewriting and write the tests.
03 — SIGN-OFF
A named engineer owns it.
Nothing we ship goes out until they have put their name on it.
That process is why the test suite, the security pass and the architecture review are included rather than cut. They are usually the first things to go when a budget is tight, and they are the reason apps break later.
What we have shipped
Much of our work is under NDA. So here are the specifics.
Regulatory rules from 1,994 sources, ingested into a citation-grounded, jurisdiction-aware system.
A BI platform deployed inside the customer's own AWS account. Their data never leaves it.
SLA breach rate cut by more than half on a live production platform.
Client engagements across insurance, health, legal and financial data.

I’m confident with their deliverables – I can see their code, and their work requires minor changes. They’ve also asked questions whenever we encounter difficulties, and they’ve come up with novel solutions that I haven’t thought of.
Andrew Wallace
Founder, Vimocard
I’m impressed with Zenveus’s speed and autonomy. The team always comes up with solutions instead of asking what they need to do.
Nazar Synchuk
CEO, Hold-IT (ReqMe)
Very good work, design was spot on – I am very happy with the outcomes. Clean fresh design, got what I wanted, with little to no amends – I’m happy to work with Zenveus again and I recommend them.
Andrew Rhose
Founder, Stylist
When we are the wrong choice
We'll tell you before you pay us.
Two situations where you should hire someone else, and we would rather say so now than three weeks in.
You want a demo built cheap and fast
That is a different job and there are people who do it well. We are who you call once it exists and has to hold up.
You want the lowest price
We are not it, and the gap is the review, the tests and the security pass.
Questions
What founders ask us.
Zenveus helps product teams audit or take over existing software, make architecture and delivery decisions for new builds, and add senior-led capacity to a live roadmap. The work connects architecture, implementation, QA, release evidence and operational handoff.
That the product has evidence across nine published checks: authentication, authorization and isolation, secrets, input handling, transactional integrity, performance, automated testing, observability and deployment, and compliance and audit surface. The Standard publishes how those checks become a verdict.
The self-check gives your team a structured, evidence-based first pass. The $299 verdict adds independent senior judgment: continue, repair, selectively replace, or rebuild, with the reasoning and next sequence written down.
The $299 verdict establishes what should remain, what needs work, and which evidence is missing. Remediation is then scoped from the actual findings instead of a generic calculator or an uninspected feature list.
The evidence supports four possible outcomes: continue, repair, selectively replace, or rebuild. The recommendation should preserve validated product behavior while addressing the constraint that actually blocks safe delivery.
Often the existing team can implement the repair. An independent verdict is useful because it separates diagnosis from the commercial incentive to sell a larger rebuild or replacement project.
Yes. Build It Right starts with the outcome, critical workflow, system boundaries, expensive-to-reverse decisions, and the evidence that will prove the first milestone works.
A sprint is a fixed block of senior engineering with an end date, priced for flexibility. A pod is an embedded team that stays, learns your product once, and keeps shipping with QA and a lead engineer included. Four sprint weeks cost more than a month of a pod, deliberately. If you need continuity, the pod is better value and we will say so rather than selling you sprints.
AI writes the first draft, a senior engineer reviews and rewrites what needs rewriting and writes the tests, and nothing we ship goes out until a named engineer signs off. That is why the test suite, the security pass and the architecture review are included rather than cut.
Much of our work is under NDA. Instead of implying client endorsement, we publish attributable delivery specifics: 35,643 regulatory rules from 1,994 sources, an in-account BI platform with zero data egress, and an SLA breach rate reduced from about 14% to under 5.5%.
No. Insurance and healthcare are where our domain depth is most specific. The same production disciplines also apply to FinTech, B2B SaaS, legal systems and operational products.
The self-serve resources are available immediately. Review and delivery timing depends on the evidence required, repository access, the decision deadline and current senior-review capacity.
Wherever your product is, start there.
