SRB Ventures Research

Investment Thesis

SRB Ventures is a stage and sector-agnostic venture capital fund founded by Sahil Bloom, the renowned creator behind The Curiosity Chronicle newsletter with 800,000+ subscribers. The fund leverages Sahil's unique distribution platform, direct founder relationships, proprietary fund partnerships, and post-investment support strategies to identify and accelerate high-growth startups.

The investment philosophy emphasizes:

  • Founder-centric approach: Backing exceptional founders with clear vision and execution ability
  • Platform leverage: Using Sahil's 800,000+ newsletter audience and media platform to provide unique post-investment value
  • Network effects: Direct relationships with top-tier founders and operators across multiple industries
  • Operational support: Structured founder programs including company design frameworks and strategic guidance

Fund Overview

Fund Name: SRB Ventures Managing Partner: Sahil Bloom Fund Size: $10 million (Fund I, raised February 2022) Status: Actively deploying (as of early 2026) Location: San Diego, California / U.S.-based Website: https://www.sahilbloom.com/fund

Investment Stage and Check Size

Primary Stage Focus:

  • Pre-seed: $25K - $500K
  • Seed: $500K - $1M
  • Series A: $1M+ (follow-on reserved capital)

Typical Check Size: $25K - $1M range, consistent with early-stage focus. The fund demonstrated willingness to write checks from $25K for pre-seed investments up to $1M for seed-stage companies.

Portfolio Concentration: The fund maintains reserves (approximately 50%) for follow-on investments in existing portfolio companies, indicating commitment to founder success and ability to support later rounds.

Geographic Focus

  • Primary: United States (especially Silicon Valley, San Francisco Bay Area, New York)
  • Secondary: Emerging tech hubs across North America
  • Philosophy: Stage and sector-agnostic means willingness to invest across geographies if founder fit is exceptional

Sector and Model Preferences

The fund is stage and sector-agnostic, meaning it doesn't restrict itself to specific industries. However, based on portfolio analysis and Sahil's public interests, the fund has demonstrated interest in:

Sectors:

  • Enterprise software and developer tools
  • Consumer apps and platforms (theSkimm, Glamsquad)
  • Fintech and financial services
  • Health and wellness tech
  • Supply chain and logistics (HopSkipDrive)
  • Consumer commerce (Carbon38)

Business Models:

  • B2B SaaS and developer platforms
  • Direct-to-consumer (DTC) brands
  • Marketplace and networking platforms
  • Technology-enabled services

Decision Process and Timeline

Decision Structure: Solo GP with advisory network. Sahil Bloom makes final investment decisions with input from a network of advisors and operators.

Decision Timeline: Conservative estimate 2-4 weeks, given the smaller fund size and Sahil's other commitments (newsletter, holdings company, speaking).

Warm Introductions: Strongly preferred but not required given Sahil's existing network.

Typical Board Involvement: Observer or advisor role in most cases, though willingness to take board seat in select high-conviction investments.

Lead vs. Follow Tendency

Primary Tendency: Leads and follows strategically

  • Leads when founder fit aligns and Sahil has conviction on the problem/solution
  • Follows when alongside strong lead investors (top-tier VCs: a16z, Sequoia, Lightspeed)
  • Writes smaller checks ($25K-$100K) that slot alongside top-tier leads when appropriate
  • Brings platform value even in smaller check sizes

Founder Preferences

Profile:

  • First-time founders welcome (but experienced founders preferred)
  • Technical founders with clear vision
  • Founders who value operational excellence and continuous learning
  • Builders with growth mindset and curiosity

What Resonates:

  • Clear articulation of founder journey and why solving this problem matters
  • Evidence of customer traction or strong product sense
  • Alignment with Sahil's core interests: growth mindset, operational excellence, leverage
  • Founders who are visible/building in public
