We don’t decorate. We solve.
Tsunami sits where design thinking meets business transformation: brand, product, and design-led build for teams that need speed, revenue, retention, and alignment, not another agency retainer that eats runway. Tell us where friction lives; we’ll show you what to ship first.

“We stopped debating and started shipping.”
The sprint forced a decision our exec team had circled for two quarters. We had a tested direction in a week - and finally told investors what we were building, not what we might try.

“Sales and product finally said the same thing.”
The brand work wasn’t a logo exercise - it was positioning we could use in decks, on the site, and in onboarding. Retention ticked up once the story matched the product.

“No handover cliff.”
Design stayed through build. Fewer ‘that’s not what we meant’ cycles - we got to launch without burning the eng team.

“The audit paid for itself in a month.”
They named where we were bleeding conversion and trust - with a fix list we could execute. Fastest ROI we’ve bought from an outside team.

Investor-ready narrative

build
From prototype to release
Alignment breaks when juniors interpret a brief three times removed from the decision-makers. We keep the chain short so revenue, product, and brand stay in sync.
Most digital experiences quit before conversion
Weak narrative, fuzzy IA, trust gaps - pick your leak.
We design for decision speed and measurable lift
Illustrative benchmark - your baseline lives in your data.
When the story matches the product, retention and conversion stop being a mystery. We build so your next experiment has a hypothesis, not a hope.
Regulated flows, PLG funnels, brand relaunches - patterns transfer. You get judgment forged in shipping, not theory from a pitch deck.
Representative work - names anonymised where needed. Ask us for sector-specific references.
