Selected work / 01—09

Nine experiments in making software feel more capable—and more alive.

Story production01

StoryCat

An AI-native directing studio that takes a story from raw idea to produced artifact—coordinating research, writing, voice, image, and publishing through durable workflows.

Collaborative writing02

Margins

A private, real-time writers’ room where invited collaborators shape drafts together, see whose hand changed what, and turn thoughtful edits into a learning signal.

Financial intelligence03

TaxCat

Conversational tax preparation that reads documents, remembers a filer year to year, and keeps every calculation inside an auditable rules engine—not inside the AI.

Human connection05

Aranem

An experience-first dating concept. The AI learns, curates, coordinates, and reflects; people meet in the real world and discover compatibility through meaningful shared action.

Music sketching06

MidiGen

A playful, phone-first MIDI sketchpad. Play or hum a phrase, capture its rhythm, shape each note, hear it through real instruments, and carry the idea into a DAW.

AI composition07

ScoreCat

Bring a tiny musical phrase—or describe one—and compose through conversation. You can even import a phrase directly from MidiGen. ScoreCat develops it into a full multi-instrument score you can read, hear, refine, and export.

Agent-native email08

MailCat

Real inboxes and Resend delivery, rebuilt around an adaptive agent. No folders, labels, or categories—just ask, teach it what matters, and turn the flood into a laser-focused beam of truth.

Daily puzzle / Very beta09

ColorPour

A whimsical color-sort puzzle. Pour matching colors into the same tubes in as few moves as you can. Keep a local streak and unlock a bonus puzzle when you solve it. Very beta—we’re still working out the kinks and building much harder challenges!

From spark to working system.

We build by following the interesting problem all the way down: from the feeling an experience should create to the quiet infrastructure that makes it dependable.

01

Find the human tension

Start with the frustration, curiosity, or possibility that makes the idea worth pursuing.

02

Make it tangible

Turn the premise into an interface people can see, touch, question, and improve.

03

Build the real engine

Give the concept honest data, durable workflows, and boundaries it can rely on.

04

Keep following it

Let use reveal the next idea. The best products teach us what they want to become.

Have an idea with a little electricity in it?

We like unusual problems, ambitious prototypes, and conversations that begin with “what if?”
