RIGETTI COMPUTING

Chad Rigetti was a researcher at IBM's quantum computing lab, working on superconducting qubits. He left in 2013 because he believed IBM was too cautious about commercializing quantum technology.

He founded Rigetti Computing in Berkeley with the audacious plan to build quantum computers from scratch — including designing and fabricating the quantum chips himself, rather than outsourcing to a third party. He built Fab-1, a dedicated quantum chip fabrication facility in Fremont, California.

This vertical integration (designing and manufacturing in-house) was unusual and expensive, but it gave Rigetti complete control over the hardware stack.

Rigetti operates a quantum computing cloud platform called Quantum Cloud Services (QCS). Customers access Rigetti's quantum processors through the cloud and pay per use.

They also offer Quil, their quantum instruction language, and Forest, their development SDK. Revenue comes from cloud access fees, government contracts (Department of Energy, DARPA), and enterprise partnerships.

Like other quantum companies, revenue is still modest, but the target market (drug discovery, optimization, machine learning acceleration) is enormous.

Rigetti Ankaa is their latest quantum processor family with improved gate fidelity. Quantum Cloud Services (QCS) provides cloud access to Rigetti processors.

Quil is their quantum instruction language. Forest SDK provides development tools.

Fab-1 is their in-house quantum chip fabrication facility — one of the only dedicated quantum chip fabs in the world.

Rigetti's strategy is full-stack ownership. By designing and manufacturing their own chips, they can iterate faster than competitors who depend on external fabs.

Their Quantum Cloud Services platform makes their hardware accessible to developers worldwide. They've pursued government contracts aggressively — DARPA and DOE have been important early customers and validators.

Going public in 2022 gave them capital to invest in next-generation multi-chip quantum processors.

Rigetti faces brutal competition from much larger players — IBM, Google, and Amazon all have superconducting quantum programs with vastly more resources. Running a chip fab is expensive and capital-intensive, putting pressure on Rigetti's cash reserves.

The company has gone through leadership changes and cost-cutting rounds. The stock's volatility since going public has tested investor patience.

And the fundamental challenge remains: no quantum computer yet delivers consistent commercial value.

Andreessen Horowitz was an early and significant investor. DCVC (Data Collective), Bessemer Venture Partners, Franklin Templeton, Y Combinator (Rigetti was a YC company), and Vy Capital have all invested.

The SPAC merger with Supernova Partners II brought public market capital. Government funding from DARPA and the DOE has also been important.
