Securing the Stack:
From Codebase to User.

Fast-shipping apps break at two layers — the infrastructure nobody sees, and the interface everybody uses. We audit both, because a hardened backend means nothing if your auth flow leaks trust.

We audit, redesign, and build — full sprints from zero to deployed. Web, app, UX, accessibility, security, architecture. A team that's shipped to millions.

Why teams hire us

The three things stopping you from shipping.

Founders and vibe coders hit the same wall — the prototype works, but it's nowhere near safe enough for real users. Here's where we come in.

Ø1 — USABLE
Confusing flows, lost users
!
AI-generated screens forget the screens before them. Onboarding drifts, dashboards lose navigation, accessibility is an afterthought — and users get lost on screen four.
Real user flows, journey maps and accessibility from day one — designed by veteran product designers who understand what people actually need to do, not what an LLM thinks looks nice.
30+ years of UX heuristics regularly violated by AI-generated UIs— Nielsen Norman Group, 2024–25
Ø2 — SAFE
Built fast, breaks faster
!
Vibe-coded apps ship with leaked secrets, public-by-default data, SQL injection holes and architecture that buckles the moment a real user signs up.
Battle-tested code, architecture and security reviews that catch the vulnerabilities your AI agent missed and make the product safe to put in front of paying customers.
45% of AI-generated code ships with classic OWASP Top-10 vulnerabilities— Tenzai & Wiz scans of 5,600 vibe-coded apps, 2025
Ø3 — LAUNCHABLE
Demo-ready ≠ release-ready
!
Looks great in dev, falls apart in production. Empty states break, queries time out, payments leak, mobile is unusable — the polish your AI never finished.
Design and infrastructure polish that closes the last mile between "demo-ready" and "release-ready" — so your first 1,000 users don't become your last.
1.7× more issues per pull request when AI co-authors the code— CodeRabbit / DORA State of AI-assisted Dev, 2025
What we do

Launch, build, rescue — or maintain.

A veteran studio that splits time evenly between design and engineering. We help founders and vibe coders go from idea — or AI-generated prototype — to a product that survives real users.

Ø1
Launch Sprint
Every foundation locked in before a single line of production code: discovery, user flows, information architecture, accessibility, a working design system, a clickable prototype and the technical architecture to build on.
Ø2
Build Sprint
Battle-tested design and engineering end-to-end. Whether starting fresh or replacing an AI-built prototype — frontend, backend, auth, database, CI/CD, cloud, testing and launch.
Ø3
Product Rescue Sprint
Review and harden vibe-coded or AI-generated apps across UX and engineering — accessibility, user flows, security, performance and architecture cleanup.

What we cover

Vibe-coded with AI? We help make it production ready.

We audit AI-generated, fast-built and inherited apps across UX and engineering — closing the gaps that stop a working prototype from surviving real users.

Design layer

UX, flows, accessibility & visual coherence

The half AI gets ugly fast — usability, IA, content and accessibility audits that turn a generated UI into a product real users can actually navigate.

UX heuristic audit
Review your existing UI against Nielsen heuristics — surface friction, ambiguous labels, broken mental models and screens that fight the user.
Accessibility audit (WCAG 2.1 AA)
Contrast, keyboard navigation, focus order, ARIA, screen-reader flows — find the ableist defaults your AI baked in.
User flow & journey review
Map what users actually experience vs. what the prototype assumes — surface drift, dead ends, lost navigation and missing states.
Information architecture review
Navigation, hierarchy, taxonomy and labelling — fix the structural confusion that no amount of UI polish can paper over.
Design system audit
Find inconsistent components, drifting tokens, duplicated patterns and the AI-generated one-offs that make the product feel held together with tape.
UI consistency & visual hierarchy
Type scale, spacing, colour, weight and grid — make sure every screen reads as one product, not nine.
Content & UX writing review
Microcopy, error messages, empty states, button labels — replace the bland defaults LLMs love with copy that helps users actually do the job.
Onboarding & empty states
First-run, zero-data, error and edge-case screens — the moments your AI never finished and your investors notice first.
Mobile & responsive review
Cross-device usability, touch targets, gesture patterns and breakpoints — make sure the product works where most of your users actually open it.
Engineering layer

Code, security, performance & scale

The half that breaks under real traffic — architecture, security, infra and performance audits that take a vibe-coded prototype to production-ready.

Code quality & architecture review
Identify structural issues, anti-patterns and maintainability risks before they compound into blockers.
Security audit
Authentication, session management, API exposure, dependency vulnerabilities and secrets scanning.
Penetration testing
Real-world attack simulations targeting your app's most critical surfaces and third-party integrations.
Package upgrades
Dependency audit and prioritised upgrade roadmap — so you're not shipping with known CVEs or abandoned packages.
Performance review
Full frontend and backend performance analysis — load times, render blocking, memory leaks and bottlenecks.
SSR, caching & CDN optimization
Server-side rendering strategy, cache invalidation logic and CDN configuration for global performance.
Database optimization
Index analysis, slow query review, schema refactoring and long-term data architecture improvements.
Cloud infrastructure review
Identify over-provisioned resources, reduce cloud spend and improve infrastructure resilience and observability.
Scalability review
Assess your system's readiness for 10x growth — queuing, rate limiting, horizontal scaling and failover strategies.

Sprint Toolkit™

What's inside every sprint.

A fixed kit of deliverables that every engagement runs on — so you always know what you're getting, and we always know what we're shipping.

Ø1
UX Research & User Flows
Discovery, user interviews, jobs-to-be-done and end-to-end flows mapped before a pixel is pushed — so the product solves the right problem.
Ø2
Information Architecture & Journeys
Navigation, hierarchy and journey mapping so onboarding doesn't drift and dashboards don't lose people two clicks in.
Ø3
Performance & Infrastructure
SSR, caching, CDN, deployment pipelines, monitoring and cloud cost review — production-grade speed, scale and observability.
Ø4
Security & Pen Testing
Authentication, API and session review, vulnerability scanning, dependency audits and penetration testing.

Feasibility reviews, wallet integrations, on-chain flows and AI tooling recommendations for modern product stacks.
Latest projects

Recent work we shipped.

A selection of products we've designed, built and scaled — from on-chain games to venture-backed Web3 platforms with millions of users.

Good engineering doesn't just make a product work — it makes it secure, scalable, and maintainable. Most teams only realize this when it becomes the thing standing between them and their next milestone.

Testimonials

What founders and builders say about us.

A few words from the teams we've helped raise, launch, and ship to real users.

Provel rebuilt our brand and product UI in under two weeks. The deck and prototype landed our seed round — the difference between good idea and fundable company.

LL
Ani Ziska, CEO Lizard Labs

The design sprint gave us something our users actually understood. Fast, considered, and built to last — exactly what we needed before our next raise.

IL
James, Head of Product Launchpad

The tech audit caught issues we'd been arguing about for months. Specific, prioritised, actionable — and delivered faster than we thought possible.

LP
Adrian, Senior Engineer Aventus
The team behind it

Veteran leads, no hand-offs.

Every project is run by the same two people who'd pitch you on the call. No agency layers, no junior swap-outs.

FAQ

Common questions.

01Who are the team?+
A small, intentionally lean group of veteran designers and engineers based in Dubai — each averaging 10 years' commercial experience across global brands and venture-backed startups. Design and engineering work side by side from day one, so there are no gaps, no hand-offs, and no middlemen. Every project is handled at the lead level. You'll always be working with the people who actually make decisions.
02What's your engineering stack?+
We ship production-grade full-stack products in React, Next.js, Node.js, NestJS, and TypeScript — deployed to Vercel, AWS, or your preferred cloud. On the Web3 side: Solidity smart contracts (ERC-20, ERC-721, ERC-1155, ERC-4626), Hardhat, and battle-tested on-chain patterns including staking, governance, token launches, and NFT infrastructure. Design tools: Figma, Framer, Lottie. We're opinionated about quality and pragmatic about tools.
03Do you actually build the product, or just design it?+
Both — that's the point. Senior designers and engineers on the same team, shipping together. The person who designs the flow writes the code for it. No handoff friction, no "design intent lost in translation," no second vendor to manage. You get production-ready output — not a Figma file and a goodbye.
04Who owns the codebase?+
You do. Full source, your repo, your Vercel project. We document the architecture and hand over keys at the end — or stay on a Marathon retainer if you'd rather we keep building. No lock-in, no proprietary CMS, no surprises.
05Are there refunds if I'm not happy?+
We work iteratively with you the whole way through, taking feedback at every checkpoint to keep us aligned. Our case studies and testimonials are the best read of what to expect — and we'd rather get the work right than the refund.
06What's the Launch Sprint 10-day delivery guarantee?+
For the $32K guarantee variant, if we miss the agreed day-10 demo deadline for reasons inside our control, we credit you 25% of fee (refunded or applied to a future engagement). Read the full guarantee terms for what counts as "inside our control" — TL;DR: scope creep, missing client assets, or new requirements added mid-sprint pause the clock.
07Do you work with non-startups?+
Yes. We work with teams in any industry — startups, enterprise, retail, gaming studios — wherever the product needs clear thinking and confident execution.
08Can you handle a tight deadline?+
Yes. Some projects need a fast turnaround — a launch, a pitch deck, a last-minute update. If the scope and timeline are clear we can prioritise and allocate resources to deliver high-quality work fast.
09Do you understand wallets, token gating, and on-chain flows?+
Yes. Hands-on experience designing and building for Web3-specific flows — wallet connections (MetaMask, WalletConnect, etc.), token-gated content, and interfaces visualising on-chain data — built to be intuitive even for users new to Web3.
10What exactly does an audit cover?+
A Provel audit is a senior, multi-track evaluation across four dimensions: UX & product experience (journey mapping, heuristic evaluation, friction points, onboarding), technical performance (load times, p95 latency, platform parity, crash patterns), competitive position (local and international benchmarking, positioning gaps), and growth strategy (retention levers, feature gaps, north star clarity). Every finding is severity-scored — High / Med / Low — and the final output is a ranked, prioritised roadmap with quick wins and a 30/60/90-day action plan. You also get a live readout with open Q&A.
11How long does an audit take, and what do you need from us?+
The standard Audit runs 10 business days from kickoff. Audit Lite is 5 days; Audit Pro is 4 weeks. To get started we need access to your app (staging or production), analytics (GA, Mixpanel, or equivalent), and any existing design files. We handle the rest independently — you're not blocked from your work while the audit runs. We'll schedule one 30-min kickoff call and one final readout.
12What happens after the audit?+
Most teams move straight into a sprint. We've structured our sprints to pick up exactly where the audit leaves off — the roadmap becomes the brief, and we start executing the highest-severity items first. You can run the audit findings with your own team, bring us in for specific sprints, or start a Marathon retainer for continuous progress. No obligation either way — the report is yours to keep.
13Do you sign NDAs?+
Yes. We're happy to sign an NDA to protect your project details, IP, or confidential roadmap — especially around early-stage concepts and unreleased products.
14How involved will we be in the process?+
Collaborative by default. We loop you in at direction, strategy, feedback and approvals — design and engineering checkpoints. If your schedule is packed we can lead end-to-end and make decisions grounded in best practice and research — either way, the result reflects your goals.
