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.
95.9% of the top one million home pages have detectable WCAG accessibility failures— WebAIM Million, 2026
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.
2,000+ high-impact vulnerabilities found in apps built with vibe-coding platforms— Escape
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.

AI writes the code. We catch what it misses.

Here's a wallet an AI tool generated, and what Provel's scanner flags in it. Run the same 39 checks on your own site, free, in about a minute.

You ask an AI tool for an app.

A few seconds later there's a working wallet with social login and NFT support. It looks finished.

The code ships. Nothing looks wrong.

The button connects and the page loads. The problems are in what you can't see: security, accessibility, speed and the edge cases.

0x scans it.

39 checks across speed, SEO, accessibility, mobile, security and more, plus an AI design review of the page.

You get the list, ranked.

What to fix first and why. Fix it yourself, or have Provel fix it.

What we cover

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

We audit AI-built and inherited apps across UX and engineering, so your prototype survives 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
Find the friction, unclear labels and screens that fight your users.
Accessibility audit (WCAG 2.1 AA)
Contrast, keyboard and screen-reader checks so everyone can use it.
User flow & journey review
Map the real journey and fix dead ends and missing states.
Information architecture review
Clear navigation, structure and labels users can follow.
Design system audit
Clean up drifting tokens, duplicate components and AI one-offs.
UI consistency & visual hierarchy
Type, spacing and colour that make every screen feel like one product.
Content & UX writing review
Sharper microcopy, errors and labels that help users get things done.
Onboarding & empty states
First-run, empty and error screens your AI never finished.
Mobile & responsive review
Make it work well on the phones most users open it on.
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
Spot structural issues and risks before they become blockers.
Security audit
Auth, APIs, dependencies and leaked secrets, checked.
Penetration testing
Simulated attacks on your most critical surfaces.
Package upgrades
A clear upgrade plan so you never ship known vulnerabilities.
Performance review
Faster load times and fewer bottlenecks, front to back.
SSR, caching & CDN optimization
Rendering, caching and CDN setup for speed everywhere.
Database optimization
Faster queries and a schema that scales.
Cloud infrastructure review
Lower cloud spend, better resilience and monitoring.
Scalability review
Get ready for 10x growth without falling over.

Sprint Toolkit™

What's inside our sprints.

The building blocks our sprints are made from — 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.
Ø5
Design System & UI
Visual language, component library and high-fidelity UI — a scalable system your team and your AI tools can both ship against without drift.
Ø6
Accessibility & Content Strategy
WCAG 2.1 AA pass, screen-reader and keyboard flows, plus content design and UX writing — so your product works for the 1 in 5 your AI didn't think about.
Ø7
Technical Architecture
Stack decisions, API design, schema and indexing, framework recommendations — made before a line of production code is written.
Ø8
AI & Web3 Advisory
Feasibility reviews, wallet integrations, on-chain flows and AI tooling recommendations for modern product stacks.
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 helped us build out our studio and products — from brand to product UI. The deck and prototype landed our seed round, the difference between good idea and fundable company.

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.

LP
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.

FAQ

Common questions.

01Who are the team?+
A small, intentionally lean group of veteran designers and engineers based in Dubai — each with years of 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.Meet the team
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: Provel One, our in-house design canvas, plus Framer and 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 design 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 Maintenance 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.
06Do 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.
07Can 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.
08Do 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.
09What 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.
10How long does an audit take, and what do you need from us?+
The standard Audit runs 10 business days from kickoff. The Rescue Sprint's review is 5 days; Strategic Audit 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.
11What 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 Maintenance Retainer for continuous progress. No obligation either way — the report is yours to keep.
12Do 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.
13How 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.

Good engineering doesn't just make a product work. It makes it secure, scalable and maintainable.
