## Notes
- Runs customer engineering at Cognition (maker of Devin and, since the 2025 acquisition, Windsurf); a 2026 post on Cognition's GTM org lists him as running customer engineering inside a Deployed Engineers group of roughly 95 people, with Palantir as the largest feeder of FDEs. (https://www.linkedin.com/posts/isabelle-i_this-is-the-sales-team-behind-cognitions-activity-7523093721865850880-mxWB)
- Quoted by press on Devin usage limits, verbatim: "The limits that a user should have should not be static. They should be dynamic." (https://www.tokenpost.com/news/technology/34146)
- The Information quoted him, verbatim: "They should be dynamic based on the efficiency of your usage and the value that you're getting out of it", on Cognition tying token limits to how efficiently engineers use Devin. (https://www.theinformation.com/newsletters/ai-agenda/cognitions-plan-limit-tokenmaxxing-efficient-engineers)
- Joined Cognition in 2024 directly after shutting down his own startup Refractive. (https://www.linkedin.com/posts/isabelle-i_this-is-the-sales-team-behind-cognitions-activity-7523093721865850880-mxWB)
- Co-founded Refractive (2022-2024), a partner intelligence and engagement platform that enriched Crossbeam/Reveal data for rep-to-rep collaboration, with co-founder Shubhra Ganguly; both were ex-Databricks engineers who saw ecosystem partners struggle to drive revenue there. (https://www.linkedin.com/posts/shubhrakanti-ganguly-454439114_partnerships-ai-datadriven-activity-7118267430119899137-lhWx)
- Likened Cognition's automatic limit increases for efficient Devin users to how credit cards raise limits for good stewards. (https://aidailybrief.beehiiv.com/p/the-most-important-ai-news-this-week-is-getting-overlooked)
- Speaker as "Head of FDE @ Cognition" on the Forward Deployed panel "The Future of Agentic Engineering" (with Semgrep, Factory and Composio) in San Francisco on March 19; the episode chapters include a segment on the Windsurf acquisition. (https://luma.com/lzk5s1td)
- Co-founder Shubhra Ganguly later joined Cognition as a Deployed Engineer in 2026 after LiveKit, so Giroud effectively re-recruited his Refractive co-founder into his own org. (https://www.linkedin.com/in/shubhra-ganguly-454439114)
- Posted on X around the SWE-1.5 launch in Windsurf (Oct 2025), per Techmeme's capture: "Speed is the next frontier! Very excited to be at the forefront of this". (https://www.techmeme.com/251030/p37)
- Multiple new hires thank him publicly on joining, e.g. Jude Partovi (GTM, left school to join), Benjamin L. (Deployed Engineer), Kyle Coapman (GTM Ops working with customer engineering) and Kevin Lee (APJ).

- Software Engineer at Nuro 2018-2020 (Mountain View); Windsurf co-founder Anshul Ramachandran was a Technical Lead Manager at Nuro, an overlap that predates Cognition's acquisition of Windsurf. (https://www.linkedin.com/in/anshul-ramachandran)
- Public headline says "Building Cognition". (https://www.linkedin.com/in/calvin-giroud-9667a8100)
- Open source: co-authored with Ross Coker "an optimized, fully concurrent lock-free cuckoo hash table implementation" in C++ for CMU 15-418, benchmarked against std::unordered_map; hosted on his GitHub account eourcs. (https://eourcs.github.io/LockFreeCuckooHash/proposal)
- Posted on X, verbatim: "Man comes in and immediately places 1st in our company wide poker tournament. Welcome to the team!", a glimpse of Cognition culture and of him personally welcoming hires. (https://x.com/calvingiroud/status/2079695260725518515)
