Background

Steve Bragonier is a co-founder and the Chief Financial Officer of Neotribe Ventures, the Menlo Park–based early-stage venture firm launched in 2017 by longtime NEA general partner Swaroop "Kittu" Kolluri (alongside co-founders Aditya Singh and Bragonier). As CFO, Bragonier runs the firm's finance, fund operations, and administrative function rather than sourcing or leading investments — the firm now manages more than $480M across multiple funds.

Bragonier is a career finance executive who spent much of his pre-Neotribe life as a startup CFO and financial consultant. He previously served as CFO and consultant through his own Bragonier Consulting practice, and held senior finance roles at technology companies including Telegent Systems, Flashpoint Technology, Siros Technology, and Silicon Graphics (SGI Canada). His stated track record emphasizes building financial systems and processes for early-stage companies and generating savings through tax-structuring initiatives — the operational, back-office skill set that a growing multi-fund VC platform relies on.

He holds a BA in Economics from Stanford University and an MBA in Finance and Accounting from the USC Marshall School of Business.

Investment Thesis & Focus

  • Neotribe's core thesis is investing in "breakthrough technologies that stretch the imagination" — backing entrepreneurs with audacious ideas that challenge the status quo.
  • Concentrates on early-stage deep tech: applied AI/ML, data science, enterprise software, security and software infrastructure, robotics, climate tech, and computational biology.
  • Invests across pre-seed through Series A, with a separate Ignite fund for Series B+ companies that have demonstrated product-market fit; the firm can and does lead rounds.
  • Positions itself as a hands-on, founder-first partner offering mentorship, operational support, and network access — the operational-support angle is directly relevant to Bragonier's finance/ops role.
  • Note on Bragonier specifically: as CFO/co-founder he is the firm's financial and operational principal, not a deal-sourcing investment partner. Investment decisions and board seats run through Kittu Kolluri and the managing directors/partners.
