Venture capital firm Stage 2 Capital has raised a combined $100 million across two new investment vehicles, Venture Fund IV and Catalyst IV, as it expands its backing of business-to-business artificial intelligence companies.
The Boston, Massachusetts-based firm said the funds will enable it to support B2B AI startups at different stages of development, ranging from pre-seed ventures to companies preparing for Series A funding.
Two Funds Target Startups at Different Stages
The two funds will operate with different investment strategies and funding amounts.
Venture Fund IV will invest between $2 million and $5 million in companies at the Seed and Series A stages.
Meanwhile, Catalyst IV will focus on pre-seed startups, making investments of $200,000, often as part of their first institutional funding rounds.
Together, the funds are designed to provide financial support to AI businesses from their earliest stages through subsequent growth phases.
Founders to Gain Access to Experienced Technology Operators
Beyond financial backing, both funds will give portfolio founders access to experienced go-to-market (GTM) professionals from some of the world’s leading technology companies.
The network includes operators with experience at OpenAI, Anthropic, Lovable, Snowflake, Databricks, SpaceX, Harvey and ServiceNow, alongside dozens of other established companies.
These professionals will work with founders to develop the commercial foundations and strategies needed to support scalable business growth.
Stage 2 Begins Investing in AI Startups
Led by Co-Founders and Managing Partners Mark Roberge and Jay Po, Stage 2 Capital has already started deploying capital from the newly raised funds.
Among the AI companies receiving backing are Letter.ai, Qualitate and Axle.
The firm’s investment approach involves its partners working directly with every founder and company they support.
Firm Introduces AI Agent for Portfolio Support
Stage 2 Capital is also incorporating artificial intelligence into its internal operations through its MCP agent.
The system is intended to give portfolio founders real-time access to the talent, expertise and professional connections within the firm’s network of more than 1,000 limited partners (LPs).
Through the initiative, the firm is expanding the resources available to its portfolio companies beyond direct investment and hands-on support from its partners.
