Let's Talk

Design That Keeps Pace With a Funding Cycle

Bay Area roadmaps are set by capital events. A round closes, eighteen months of runway starts ticking, and every quarter has to show a defensible jump in the metrics your next investor will diligence. Design either accelerates that clock or quietly burns it. We plan the work against the milestone, never against a deliverable list.

Scoped to the Milestone

We start from the number your next raise depends on and work backwards. What ships first is whatever most improves that number, not whatever is easiest to design or nicest to present in a portfolio review.

Pacific Hours, Guaranteed

Four hours of guaranteed live overlap with Pacific business hours every working day, run as an official night shift from our studio. A founder in SoMa gets answers inside their own afternoon, not on tomorrow’s call.

Runway-Aware Scoping

Every proposal states what we would cut if the budget halved and what we would add if the round closed early. Knowing the trade before you sign is worth more than an estimate that pretends the plan will not change.

Investor-Ready Artefacts

Prototypes and product walkthroughs built to survive a partner meeting: a real interaction on a real flow, not a rendered concept reel. Founders reuse these directly in diligence.

The measure we care about is whether design shortened the distance to your next milestone. Everything else in the engagement is arranged around answering that honestly.

What Bay Area SaaS Companies Bring Us

The briefs cluster by stage. Pre-seed and seed teams need to prove a proposition quickly. Series A teams need the product to stop looking like a prototype. Series B teams need it to survive a ten-times increase in accounts without the interface falling apart. Each is a different problem.

Seed-Stage Proposition Testing

Before the build, a working prototype that real prospects can use. It settles whether the idea lands while changing it still costs days rather than engineering quarters, and it doubles as material for the seed deck.

Series A Product Maturity

The moment a promising product has to look like a company. Consistent interface language, resolved empty and error states, a settled navigation model, and the design debt from the first eighteen months paid down deliberately.

Series B Scale Interfaces

Permissions, roles, audit trails, bulk operations and admin tooling — the unglamorous surfaces that decide whether enterprise buyers can adopt you. This is usually the gap between a self-serve tool and a contract with procurement.

Retention by Design

High-growth SaaS leaks users quietly. We instrument the first session, find where value arrives too late, and rebuild that stretch so the product proves itself before curiosity runs out.

Tell us the stage and the metric under pressure. We will tell you which of these the work actually is, even when it is not the one you came in asking for.

How a San Francisco Engagement Runs

Startup teams are rightly suspicious of agency process, because most of it exists to protect the agency. Ours is short, and every stage produces something you could ship or show to an investor if we stopped there.

Week One: Evidence

Product analytics, session recordings and interviews with your own users. We arrive at a ranked list of what is costing you conversion or retention before proposing a single screen.

Weeks Two to Three: Prototype

A clickable, high-fidelity prototype of the flows that matter most, tested with real users. The cheapest place to discover the idea is wrong is here, well before engineering commits.

Build Alongside Engineering

Designers work inside your sprint and your repository. Components arrive as reviewed front-end code in React, so the design system and the codebase stay one thing rather than two.

Measure, Then Decide

Changes ship instrumented. At the end of the cycle you get the actual movement in the metric, including where it did not move, which is the part that tells you what to do next.

No discovery phase that produces only a deck, and no three-month gap before anything is testable. If a stage cannot justify itself against your runway, we do not sell it to you.

Frequently Asked Questions

Do you have an office in San Francisco?

No, and we would rather say so plainly than imply otherwise. Our California office is in Sacramento and the design studio is in Ahmedabad. Bay Area clients are served from those two, with guaranteed live Pacific hours — what you get is the timezone, not a nameplate on a Market Street door.

How do you work with Bay Area teams remotely?

Four hours of guaranteed real-time overlap with Pacific business hours, every working day, staffed as an official late shift in India. Standups, reviews and live Figma sessions happen inside that window, and the build continues overnight so Monday’s decision is usually visible by Tuesday morning.

Can you help us prepare product material for a raise?

Yes. Interactive prototypes and product walkthroughs are a normal output, and founders reuse them directly with investors. What we will not do is design screens for a pitch that the roadmap has no intention of building — that surfaces in diligence and it costs more than it wins.

What does design cost for a seed-stage startup?

Quoted per scope in USD, with a written note in every proposal about what we would cut if budget tightened. Seed teams most often take a short validation engagement rather than a retainer, because it answers the question that is actually blocking them for a fraction of the commitment.

We already have a designer. Can you work alongside them?

Frequently. In-house designers at Series A companies are usually one person against a roadmap built for four. We take a defined surface — onboarding, the admin console, the design system — so they keep ownership of the product rather than being managed by an agency.

How fast can you produce a testable prototype?

For a contained flow, typically within the first two to three weeks, including the evidence work that precedes it. The variable is not our capacity, it is how quickly we can reach your users. If recruiting participants will take three weeks, we will say so rather than quietly testing internally and calling it validation.

Do you work in our React codebase?

Yes. Front-end delivery in React and Node sits in the same team as the design work, and we build inside your repository against your conventions. For most Bay Area clients the handoff is a reviewed pull request rather than a Figma link and a specification.

How do you handle NDAs and IP for stealth products?

Standard practice. We work under client NDAs and assign IP through the engagement agreement, and access is limited to the named people on your team. Stealth-stage clients are a normal part of the work and nothing appears in our portfolio without written permission.

What if the research says our idea does not work?

We tell you, with the evidence, early enough for it to be useful. A validation engagement that prevents a wasted build has done its job, even though it is the least comfortable version of the result. Reframing that finding into an encouraging summary would be the actual failure.

Do you only work with venture-backed companies?

No. Bootstrapped and revenue-funded SaaS companies are a large part of the Bay Area work, and they often make sharper clients because the spending decision is theirs. The engagement shape changes with the funding model, but the method does not.
