Costanoa Ventures

Early-stage investments in AI and security

Overview

Costanoa Ventures is a venture-capital firm that funds early-stage startups in Applied AI, AI Infrastructure, Cybersecurity, National Security, and Fintech. It invests from formation through Series A, and uses its $2.3 billion in assets under management to support a small number of companies more deeply with hands-on guidance and operational help during the critical early growth phase. Compared with many investors, Costanoa focuses on a narrower set of sectors and takes a boutique approach—making fewer investments so it can provide more expertise and active support when it matters most. The firm’s goal is to help founders build companies that have a lasting impact and scale successfully from the earliest stages.

Natter raises $23M for AI-powered employee video interviews that outperform traditional surveys

Natter has raised $23 million in a Series C round led by Renegade Partners, with participation from Kindred Capital, Costanoa Ventures and others. The startup uses AI-powered video interviews to gather employee feedback at scale, replacing traditional surveys and focus groups. The company's system enables organisations to interview thousands of employees simultaneously whilst maintaining anonymity, which encourages more candid responses. Internal research shows one customer gained more insights from 40 minutes of AI conversations than 500 hours of traditional research interviews, uncovering 97% to 147% more themes than focus groups. Natter's customers include Accenture, ServiceNow and Philip Morris. The company grew revenue fourfold in 2024 and fivefold the following year, with 80% of customers now US-based. It recently relocated headquarters from London to New York.
