Startup UX design that moves
as fast as you do

Startups don’t have time for six-month design cycles. As a startup UX design agency, we design fast, investor-ready products at a fixed monthly rate, so you launch, test and raise without hiring an in-house team.

$1B+ combined

The fastest path to a build-ready MVP.

Design that makes investors lean in.

Decisions grounded in real users.

A product that scales without rewrites.

3 to 4 weeks

From kickoff to a prototype you can demo. Agencies often quote quarters.

Week 1

User research starts before the first screen, not after launch.

0 rebuilds

A design system that absorbs new features instead of breaking.

In-house hire

A freelancer can move fast too. A large agency scopes in quarters, and hiring a senior designer takes months.

Big agencies deliver investor-grade work too, on a timeline and budget most pre-seed teams don’t have yet.

Your own team knows the users best. The question is whether anyone there has time to talk to them this quarter.

An in-house team scales best long term. The catch is hiring it before you know what you’re actually building.

What we design, mapped to your stage

Product design for startups isn’t one thing. What moves the needle at pre-seed is different from what you need at Series A, so we scope to the stage you’re actually in.

  1. Pre-Seed / MVP: Get to a product you can show. Three to four weeks from kickoff to a prototype you can put in front of users and investors. Need a working build instead? See MVP design.
  2. Seed / Growth: Turn early traction into retention. You have users. Now the job is making them come back and keeping the product coherent while the team ships faster.
  3. Series A / Scale: Make the product consistent and scalable. Three contractors, four design languages, one product. We audit, unify and hand your team a system they can build on.

How a Glow
sprint works

Six steps, three to four weeks, no twelve-week discovery phase.
Here’s exactly what happens.

1

Understanding Your Vision & Constraints

A structured kickoff on your product vision, target users, business model and real constraints: budget, timeline, team size and what’s already built. Startup design that ignores constraints isn’t useful.

Discovery

User Research & Assumption Testing

We find the riskiest assumptions, the things that must be true for the product to work, and test them the fastest way possible. That might be a five-user interview study or a clickable prototype in front of real prospects.

Insight

Information Architecture & Flow Design

Core user flows and information architecture are mapped before any visuals, so navigation matches how users think about the problem, not how the database is built.

Structure

Rapid Prototyping & Iteration

Wireframes get reviewed and iterated within days, not weeks. High-fidelity prototypes are built to the detail needed to test and hand off, no more and no less.

Iteration

Usability Testing

Real users from your audience test the prototype before engineers write code. For startups, this is where bad assumptions die cheaply.

Validation

Design Handoff & Ongoing Support

Dev-ready specs, a documented component library and organized files your engineers can build from without daily questions. We stay available during development and can support iterations as you grow.

How we
actually work

We only put seniors on it

You get a PM, a lead designer and specialists who’ve shipped in your domain. No juniors learning on your budget.

We work in sprints

Fixed cycles, each ending in a demo you can react to. You always know what’s being built and when it lands.

We already know your domain

Fintech, SaaS, healthtech, logistics. We skip the six-week ramp-up and start asking useful questions in week one.

We don’t disappear after handoff

Workshops, feedback rounds and post-release improvements. Launch is a milestone, not the end of the engagement.

We design what can be built

We walk your engineers through the work before anything is final. Our files ship. They don’t start an argument.

We’ll tell you when you’re wrong

Honest is more useful than agreeable. If a feature won’t work, you hear it from us before it’s in the sprint.

We use AI to cut delays

Not corners. Faster sprints, sharper insights and less of your budget spent on work a tool can do faster.

“About a week ago, we went a bit viral with 10k users in 2 days and we received a lot of positive feedback about the design - so thank you Glow for that!”
Israel Benarousse
CEO, Dropcall
“Glow Design Agency delivered high-quality UX/UI designs that enabled the client to close more deals. Their animated video and design gained the client almost 500+ new LinkedIn followers. The team executed work on time and within budget.

PRE-SEEDMVP DESIGN

Two founders, a clear idea and nothing to show. In three weeks we ran user interviews, designed the core flow and built a prototype real enough to demo. They closed their pre-seed with it and onboarded their first 50 beta users.

SEEDONBOARDING REDESIGN

A SaaS startup was winning signups and losing 71% of them before activation. We audited the funnel, cut onboarding steps and moved the first moment of value much earlier. Activation nearly doubled in the next cohort.

+88% activation rate

SERIES APRODUCT DESIGN SYSTEM

Three contractors had built one product, and it showed. Ahead of the Series A, we audited every screen, built one design system and rebuilt the core flows on it. That’s the product they took into the raise.

Why founders
pick Glow as their startup design agency

We’ve worked with startups from pre-seed through Series A. Here’s what founders say makes the difference.

Startup-speed delivery — no 12-week discovery for an MVP. We scope what matters for your stage and design alongside your team, not ahead of it.
Investor-grade quality — we know what investors look for. A product that looks considered reads as a team that can execute.
Research before pixels — we don’t start designing until we understand the user. Skipping that is how you build the wrong product with great execution.
Flexible engagement — by the project, on retainer, or embedded in your team. Early-stage teams shouldn’t need a full-time hire to get great design.

Frequently
asked questions

Before you build. The most common mistake is building first, struggling with adoption and only then calling a designer. Fixing a built product costs more than designing it right before engineering starts. Even basic UX design for startups, like user flows, a wireframe and a prototype to test, changes what gets built. At minimum, bring in a designer before your first sprint.

Our MVP design package is a fixed $12,500 for four weeks and ends with a working build. Ongoing product work runs on a design retainer at $12,000 a month with a PM, a design lead and a senior designer. Larger scopes get a transparent estimate after a first call, and you can start with a free 3-day trial.

Yes. A focused MVP design sprint takes 3 to 4 weeks: research or a synthesis of what you already know, core flow design and a high-fidelity prototype. The goal is the minimum needed to test with real users or pitch investors with confidence. Speed comes from scope discipline, not shortcuts on quality.

All the time. Many founders bring deep domain expertise but are new to product design. Part of our job is making the process clear: explaining decisions, involving you in the right choices and producing files your engineers can use whatever your background.

At minimum: annotated Figma files organized by user flow, a component library with documented states, a prototype you can demo and a handoff document your engineers can build from. Longer engagements add research findings, journey maps and a design system with usage guidelines. Everything is yours, with no lock-in.

Yes, and it’s common. We start with a UX audit of the live product, review analytics and user feedback and build the redesign on that evidence, without disorienting people who already know how the product works.
