About · the operating model

One builder, one marketer, one operating model, three hypotheses.

Hypoth is a studio for AI products run by Jason Grant and Karen Grant. Jason designs and engineers every experiment that ships; Karen drives the brand, the voice, and how each one gets told. The model is small and stubborn: write the question down, build something narrow to test it, set a window and a bar in advance, then publish either a continuation note or an honest post-mortem either way. Olllo and Wren are the first two experiments shaped by this.

How it works
Principle 01
Hypothesis-first, code-second.

Every experiment begins as one written sentence committed enough to test against a defined bar. The sentence sits at the top of the repo. If I can't write it, I don't build.

Principle 02
Solo, but with the discipline of ten.

Spec gates. Doc gates. Test gates. A constitution file enforced in CI. Solo dev velocity is where discipline compounds fastest — the case study on this is on the olllo page.

Principle 03
Time-boxed experiment, pre-set success bar.

Each experiment gets a defined window and a defined success bar before any code is written. When the window ends, the question gets answered: continue or sunset.

Principle 04
Public post-mortems, not pivot stories.

If the hypothesis didn't hold, the page says so — in detail, with numbers. A studio that hides its losses isn't running the experiment; it's marketing it.

The team

founder, designer, engineer

I make small things, write down what I learn, and keep the ones that earn it.

By day I'm Head of Design at Hi Marley (Series B); before that, Director of Design at Klaviyo (Series D → IPO) and a fractional VP of Design role. Across all of them, my work has lived where design, engineering, and product narrative meet.

At Hypoth I design and engineer everything that ships under the studio. I'm open to design-engineering and product leadership conversations.

I make companies shine and present their best self.

I'm a brand strategist and creative director. I've run my own branding studio for years, with a specialty in non-profits.

At Hypoth I drive the brand, the voice, and how each experiment gets told. Outside the studio, I take on select brand work.
