ZTABS provides UI/UX design — Great products start with great design. We create intuitive, beautiful interfaces backed by user research, data, and design systems that scale. From UX audits to full product design — we make complex things feel simple. Our capabilities include ux research & strategy, ui design & visual identity, wireframing & prototyping, and more.
150+ products redesigned with research-driven UX — task-completion times measured pre/post, with median improvements of 30–50% on critical flows like checkout, onboarding, and form submission.
UI/UX design is the difference between a product people tolerate and one they recommend. We've designed interfaces for 17 of our own products and hundreds of client projects — that volume of shipping experience means we know which design patterns actually work in production, not just in Dribbble mockups. Our process starts with UX research: user interviews, task analysis, competitor audits, and heuristic evaluations.
We identify where users get stuck, what they skip, and what makes them leave. Then we design solutions grounded in that evidence — not personal aesthetic preferences. We create wireframes first (low-cost to iterate on), test them with real users, and only then invest in high-fidelity visual design.
For product design, we build complete design systems in Figma: reusable component libraries with variants for every state (default, hover, active, disabled, error, loading), responsive breakpoints, dark mode support, and accessibility compliance. These systems translate directly to code — our developers implement them pixel-perfect using Tailwind CSS and Radix UI primitives. For UX audits on existing products, we use heatmaps, session recordings, and conversion funnel analysis to identify the highest-impact improvements.
We typically find 3–5 friction points that, when fixed, improve conversion by 20–40%. We design for AI interfaces too — chatbot UIs, agent dashboards, and data visualization for ML outputs — where the design challenge is making complex AI behavior understandable and trustworthy to users.

Across our portfolio, we track delivery patterns to improve outcomes. Our internal data from 2023-2026 shows:
| Alternative | Best For | Cost Signal | Biggest Gotcha |
|---|---|---|---|
| Design marketplace (99designs, Dribbble, Contra) | Landing page mockups, single-screen explorations, and brand/logo contests with predefined scope. | $300–$3K flat; typical turnaround 5–15 days (indicative). | You get visual polish without UX rigor — no user research, no journey mapping, no responsive breakpoints, no handoff specs. Development will interpret the mock and the final product drifts 20–40% from the Figma. |
| Solo freelance designer (Toptal, Dribbble Pro) | A single feature, a brand refresh, or a Figma-to-dev design handoff for an existing product with an established design system. | $60–$180/hour; typical engagement $5K–$25K (indicative). | Single-discipline risk: most solo designers are either visual-heavy (beautiful screens, weak UX) or research-heavy (great journey maps, dated visuals). Matching the right one takes 2–3 hires. Coverage drops to zero during vacation. |
| Boutique product design studio (ZTABS tier) | SaaS platforms, B2B products, and funded startups needing research + design + design system + dev handoff in one team. | $90–$180/hour; $20K–$120K per engagement (indicative). | We run discovery (1–2 weeks) before any visual work — founders who skip it regret it by week 6 when scope thrashes. Kickoff and research are typically 25% of total project cost; cut them and the output is pretty pixels solving the wrong problem. |
| Big-brand design studio (IDEO, Frog, Work & Co, Huge) | Category-defining product launches, executive-sponsored digital transformation narratives, and rebrands with $500K+ budgets. | $220–$500/hour; $250K–$3M engagements over 3–9 months (indicative). | Brand narrative sells the deal; mid-level designers deliver the screens. You're paying for the IDEO logo on the deck. Expect 2–3 rounds of 'strategic alignment workshops' before pixels move. |
| In-house product designer | Post-Series-A SaaS with a sustained design roadmap of 30+ hours/week and an existing design lead to set direction. | $160K–$240K/year loaded for senior US product designer; $80K–$130K LatAm (indicative). | Senior designers are scarce — 3–5 month hiring cycle, then 2–3 months to understand the product. A soloist hire with no design manager above them often gets pulled into marketing graphic work and the product UX stalls. |
Freelancer vs. agency. A solo senior product designer at $140/hour × 400 hours = $56K delivers a single-product redesign in 10 weeks. A ZTABS 4-person pod (research + product design + UX writing + QA) at $75K delivers the same scope in 6 weeks with coverage across disciplines. Agency premium buys parallel workstreams (research happens while wireframes iterate) and redundancy. Below $40K scope or single-discipline need, freelancer wins. Above that, agency ROI shows up in timeline compression and validated output. Design system ROI. A Figma + Tailwind design system costs $20K–$60K to build (tokens, primitives, composite components, documentation). It saves 30–50% of design+dev time on subsequent pages. Teams shipping ≥10 new screens/year recoup investment in 8–14 months. Below 5 new screens/year, skip the system and commission per-screen design. The mistake we see most: building a system before product-market fit — tokens change 3× as the product finds its shape. In-house design vs. agency retainer. A senior US product designer loaded costs ~$200K/year ($16.6K/month). A ZTABS design retainer at equivalent capacity runs $10K–$16K/month with 3–5 disciplines covered (research + product + visual + UX writing + QA). Below 1.5 FTE sustained need (~$300K/year), retainer wins on cost + coverage. Above 2 FTE, hire a design manager first, then designers — a soloist without a manager burns out or drifts into graphic production.
A 3-year-old Figma file accumulated 11 'Button/Primary' variants (old brand, new brand, 2023 refresh, etc.). At dev handoff, engineering picked the wrong one for the pricing page. Fix: archive or delete non-shipping components before handoff, use Figma Libraries + publish workflow, and name components with a clear ds/ prefix for canonical + wip/ for in-progress. Budget a 2-day library audit per quarter.
Research showed 70% of users missed the 'Upgrade' CTA in a header dropdown; moving it to the sidebar would lift conversion ~15%. An exec overrode based on their 'experience at [former company]'. 6 months later, conversion data proved research correct. Fix: make research findings executive-proof by attaching dollar-value impact estimates and getting the data-team stamp BEFORE design review. Designs without $ framing lose to HIPPO decisions.
A client launched light mode first, then added dark mode as v1.1. All vector illustrations hardcoded fill colors (#333 lines on #FFF backgrounds) became invisible on dark. 120 SVGs needed manual fixes + new token system. Fix: always design with semantic tokens (color-foreground-default, not #333) from day one, and mock every screen in both modes before handoff, even if dark mode ships later.
An external WCAG 2.1 AA audit caught 47 issues: color contrast <4.5:1 on all secondary text, missing alt text on 40% of icons, non-focusable modal close buttons, and form errors announced silently to screen readers. Retrofit took 3 weeks + $18K. Fix: run an accessibility review at wireframe stage (cheaper to fix shapes than code) and use Figma plugins (Stark, Able) during design — not after.
A design system shipped with 12 components designed only at desktop. Mobile (375px) broke: 5-column grids collapsed awkwardly, type scaled too aggressively, touch targets fell below 44×44pt. Engineering had to invent mobile layouts in code, which drifted from brand. Fix: require 3 breakpoints (375 / 768 / 1440) per component as deliverable, with explicit mobile-first rules in the handoff spec.
