The company behind the stack.

Who we are

Builder of things+ is an AI product company. We build and operate our own consumer products — designed with a director's eye, engineered with a defense contractor's discipline. Not work-for-hire; products we own and run.

Product, design, AI, and code from the same room — no telephone game between idea and launch. Every product runs on Vesper, our shared AI infrastructure, so taste and technology never drift apart.

The best ideas die in execution. The best executions die without taste. Builder of things+ exists so neither has to happen again.

II — Founder

Sam A Bombay.

Founder background

He built the launch brand for the tallest building on earth, was a founding member of a film star's billion-rupee label, and advised the office of a head of state.

Twenty-five years at the apex of brand and influence — as Chief Creative Officer & Vice Chairman of Y&R India, and Partner & Executive Creative Director in Dubai, where he founded Studio Central — across three arenas most people never touch one of: film, sport, and government at sovereign scale.

In Dubai, he was Partner & Executive Creative Director on the global launch campaign for Emaar's Burj Khalifa — positioning the tallest building on earth as the definitive address in global luxury real estate. In India, he was a founding member of HRX by Hrithik Roshan, building a film star's equity into one of the country's defining athleisure brands from the ground up. And as an advisor to the Executive Office of H.H. Sheikh Mohammed bin Rashid Al Maktoum, Ruler of Dubai, he worked where ideas don't become campaigns — they become policy, capital allocation, and the trajectory of a city.

The pattern underneath all of it: take a person, a place, or a product, and build it into something the market can't ignore. He's done category creation, brand-building, and statecraft separately. Vesper is the bet that he can run all three at once — at software margins.

Tap a card to expand

Vesper is the spine. AUDISH finds the talent, DOUBLE clones the talent, RUSH directs the talent. DARLING is consumer AI with a co-founder the world already follows. YARDLY and OUD&FORM are taste-led commerce. BOL and TEACHER X are the Bharat infrastructure layer.

Spine

Intelligence is the floor. Emotionality is the ceiling.

An intelligent assistant with emotionality. Configurable for any app. Intelligence is becoming free; every model will be smart. The difference between products won't be IQ — it'll be how the assistant inside them feels to talk to.

Vesper is built feeling-first — then made smart.

We own the pipeline end-to-end. No vendor's hidden prompt overrides the persona a product defines.

V — Approach

What we do.

01 · End-to-end

We build products end-to-end.

Product, design, AI, and code under one roof — every layer of our own products, from first idea to shipped release, with no handoffs and no drift.

02 · AI that feels

We build AI that feels.

Every product in the portfolio runs on Vesper — our proprietary assistant layer. Persistent memory, configurable personality, real-world action.

03 · Vertical bets

We build verticals.

Talent. Commerce. Consumer AI. Bharat infrastructure. Every product is a category bet — not an experiment.

VI — Difference

What makes us different.

01

Director-led, engineer-disciplined.

Most product teams are one or the other. We're both because Sam is both — twenty-five years of brand craft underneath the code.

02

Taste as a system, not a vibe.

Every product ships with a defined visual language, voice, and emotional register. Nothing gets out the door looking like AI-generated soup.

03

Vesper as the spine.

One identity layer. One memory graph. Every product we ship makes the next one better. The portfolio is the moat.

04

Speed at scale.

Most teams ship one product a year. We ship eight in parallel because the infrastructure is shared and the taste is centralized.

VII — Why now

The tools are finally good enough.

The tools just got good enough that one company can do what used to take twenty. Generative AI for film and image. Foundation models for assistants. Voice synthesis indistinguishable from a person. Edge compute that scales to a billion users from a laptop.

The taste, the timing, and the technology are finally in the same room.

Build wonderful things.
