Overview
Rigetti Computing builds superconducting quantum processors and full-stack quantum computing systems. Founded by Chad Rigetti, a former IBM quantum researcher, the company develops quantum chips, control systems, and cloud access to quantum computers. Rigetti raised a $79M Series C led by Bessemer Venture Partners in August 2020, with Andreessen Horowitz participating. The company went public via SPAC merger in October 2021, trading on NASDAQ under ticker RGTI. Rigetti operates in the superconducting qubit approach alongside IBM and Google, competing for enterprise and government quantum computing contracts. The company has faced financial challenges common to pre-revenue quantum hardware companies, including workforce reductions and restated financials post-SPAC.
Why Rigetti is interesting
Chad Rigetti's full-stack quantum approach competes with IBM and Google — Bessemer led the $79M Series C before the 2021 SPAC listing.

Competitive landscape
Edge: Full-stack approach — chips, control electronics, and cloud platform — from a team with deep IBM quantum pedigree.
Quantum computing hardware remains pre-commercial with no clear winner. Rigetti competes with better-funded IBM and Google on superconducting qubits while IonQ pursues trapped ions. Public market listing via SPAC provided capital but also scrutiny as revenue remains minimal. Full-stack integration is Rigetti's differentiation vs pure-play chip designers.
-
IBM Quantum incumbent
Market leader in superconducting qubits with largest installed base and Qiskit ecosystem.
-
Google Quantum AI incumbent
Superconducting qubits with Willow chip; research-focused with massive resources.
-

Notable stories
- Chad Rigetti left IBM's quantum research group to found Rigetti Computing in 2013, betting on superconducting qubits as the path to practical quantum computing.
- Rigetti went public via SPAC in October 2021 at the peak of quantum computing investor enthusiasm.
