We plug into your roadmap as your embedded product design partner, so you unblock UI, tighten flows, and ship the features customers keep asking for.

Book Intro Call

Product Design

Translate your post-funding product backlog into structured, shippable, done-for-you flows. We scope, design, and spec features end-to-end so your engineering teams can build with confidence.

UX Design

Reduce drop off of your highest-stakes flows. We redesign onboarding, verification, and transaction experiences to increase completion rates while staying audit-ready.

UI Design

Build a UI that signals enterprise readiness. We create scalable design systems and component libraries that keep your product consistent as your team and feature set grow

Design-to-Dev Handoff

We deliver annotated Figma files, design tokens, and documentation so nothing gets lost between design and code.

The growth-stage design gap.

Your roadmap is full. Your design team isn't.

Design Debt is Compounding

You shipped fast to hit milestones. Now your UX is a patchwork of quick fixes that breaks down every time you add a feature or enter a new market.

Designers buried in tickets

Your team is heads down on sprint work. Nobody has bandwidth to step back and build the systems, patterns, or documentation that would actually make you faster.

Compliance exposes UX gaps

Every audit surfaces the same thing: onboarding gaps, missing states, and verification logic that engineering had to guess at because the designs weren't thorough enough.

UI doesn't signal trust

You're ready to move upmarket, but your product still looks like a seed-stage MVP. Prospects hesitate because the interface doesn't match the sophistication of what's under the hood.

Senior hires take forever

You've had a req open for months. The right candidates are expensive, slow to close, and you still need to onboard them. Meanwhile the backlog keeps growing.

Agencies ship pixels, not product

Beautiful mockups that your engineers couldn't build. No specs, no edge cases, no understanding of how your system actually works.

Build a Bundle: How a Single Feature Drove 37% of Digital Revenue

Explore how our AI-first workflows helped Kenchan Ramen take “Build a Bundle” from idea to live in hours (not weeks!) and turn it into a DTC engine driving 37% of digital revenue. Customers create discounted bundles in one smooth flow, while the team retains full control over product + pricing through a lightweight UI on top of Shopify’s system.

Built to embed, not to manage

We operate as an extension of your product
team, not a vendor you have to chase

Plug into your existing workflow

We work inside your tools — Figma, Notion, Slack — so there's no context-switching or parallel systems to manage.

Compliance-aware from day one

We design with SOC2, PCI DSS, and KYC requirements in mind, so your flows don't get gutted during audit review.

Dev-ready deliverables

Every design ships with annotated specs, edge cases, and component documentation. Your engineers build from clarity, not guesswork.

Product strategy, not just pixels

We don't wait for briefs. We proactively identify UX gaps, flag flow issues, and contribute to roadmap conversations.

Async-first, meeting-light

Deep design work needs focus. We communicate through your workspace and reserve syncs for the decisions that actually need a call.

Scale up or down as needed

Ramp up for a big launch, pull back during quieter periods. No long-term contracts, no severance, no HR overhead

Designed for fintech. Built to ship.

How an engagement works

A lightweight process designed to get us productive in your codebase and roadmap fast.

1. Kickoff & alignment

We audit your current product, map your priorities, and align on the first sprint scope. By week one, we're already in your Figma, Slack, and project board.

2. Design sprints on your roadmap

We work through your highest-priority features in focused sprints, delivering dev-ready designs with specs, edge cases, and component documentation.

3. Review, iterate, ship

You review in your existing workflow. We iterate until it's right. Your engineers build from designs that are actually complete.

GROW

$8,000 / mo

Ship faster like you have a full design team.

Book Intro Call

WHAT CHANGES:

Ship 1 to 3 fully designed features per month. Each one scoped end-to-end with full user flows and interaction specs, ready for your engineers to build without guesswork.

Know exactly where your product is leaking users and revenue. A prioritized review of your existing experience with quick wins you can ship immediately and a longer-term improvement roadmap.

Your engineers build from specs, not assumptions. Annotated Figma files with interaction notes, edge cases, and responsive behavior so nothing gets lost in translation.

Every feature we ship makes the next one faster. We build and extend your component library with each engagement, so your product stays consistent and your team compounds speed over time.

Zero disruption to how your team already works. We work inside your existing tools. Slack, Figma, Linear, Notion — whatever your team already uses.

Need compliance-ready flows, full design system buildout, product strategy input, or senior design leadership? That's Scale.

SCALE

$12,000 / mo

The design leadership your product needs without the $400k hire.

Book Intro Call

WHAT CHANGES:

Ship multiple design initiatives simultaneously, not sequentially.
‍We own the full design lifecycle from research through handoff, running parallel on your highest-priority workstreams so nothing stalls waiting for design.

Your team ships 2 to 3x faster with a system that scales. A production-grade design system with reusable components, design tokens, and usage guidelines. New features get assembled, not designed from scratch

Build the right things, not just build things right. We contribute to roadmap planning, surface UX opportunities your team hasn't seen, and help prioritize what to build next based on user impact.

Pass compliance reviews the first time, not the fourth. Onboarding, verification, payments, and permissions designed with SOC2, PCI DSS, and KYC requirements built in from day one.

Your engineers build from specs, not assumptions. Annotated specs, interaction notes, edge cases, error states, empty states, and responsive behavior. Your engineers build from certainty, not assumptions.

UX Audit & Improvement Roadmap A thorough review of your existing product experience with a prioritized roadmap of what to fix, what to redesign, and what to leave alone.

Senior Design Leadership A dedicated senior designer who learns your product deeply and operates with the context and ownership of an in-house lead — not a rotating cast of contractors.

Async-First Collaboration We work inside your Slack, Figma, and project management tools. Syncs are reserved for alignment, not status updates.

Why Sari Sari over others?

We've worked in startups and Fortune 500 companies, including Meta and Disney, with combined experience of 20+ years working in tech and design. Our past work has helped raise $15M at $300M in Series A, shipped products used by hundreds of thousands of users worldwide, and more.

Our embedded product design expertise wastes less time and resources on HR bottlenecks, expensive agencies, or fragmented temp support.

What design services do you offer?

We offer a range of capabilities across the end-to-end product design process, including UX research, UX design, UI design, and custom development.

We also work with trusted partners for other creative needs, including branding, illustration, motion graphics, etc.

How is this easier than hiring a full-time designer?

A senior product designer costs $180k–$220k/yr before benefits and equity, takes months to hire, and still needs to be managed. We bring senior-level design expertise on day one with no recruiting overhead, no onboarding ramp, and the flexibility to scale up or down as your needs change.

How is this different from an agency?

Agencies scope projects, deliver mockups, and move on. We embed into your team and work continuously on your roadmap. We learn your product deeply, build institutional knowledge over time, and deliver work your engineers can actually build — not pitch decks disguised as product design.

How quickly can you get up to speed on our product?

Most engagements are productive within the first week. We start with a focused kickoff to understand your product, your users, and your technical constraints. We've worked across lending, payments, onboarding, and compliance so we're not learning fintech from scratch.

How do you handle compliance and regulatory requirements?

We design with SOC2, PCI DSS, and KYC frameworks in mind from the start. That means building for audit trails, proper data handling states, and verification flows that satisfy both your compliance team and your users. We've seen what gets flagged in audits and we design to prevent it.

How do you work with our engineering team?

Every design we deliver includes annotated specs, edge cases, error states, and responsive behavior documentation. We can work directly with your engineers in Figma and join design-to-dev syncs as needed. The goal is zero ambiguity at handoff.

What does the first month look like?

Week one is kickoff and audit — we review your existing product, map your priorities, and align on scope. By week two we're designing. Most teams see their first dev-ready deliverables within the first two to three weeks with regular updates every 3 business days.

However, more complex tasks may require further time and effort to provide the best outcome.

What if our needs change mid-engagement?

That's expected. We work in sprints and reprioritize with you regularly. If you need to scale up for a launch or pull back during a quieter quarter, we adjust. No long-term contracts or cancellation penalties.

Can we start with a smaller scope?

Absolutely. Our Grow tier is designed for teams that need dedicated design support on a focused set of features before committing to a full embedded engagement. Most Grow clients start with a specific product area — like redesigning their onboarding flow or tightening a core dashboard — and expand into Scale once they see how the work integrates with their team. We'll help you figure out the right starting point on an intro call

Do you sign NDAs?

Yes. We're happy to sign mutual NDAs before any kickoff. We understand the sensitivity of financial product work and treat client IP accordingly.
