Indexable
Spring 2026 Newsandbox infrastructure for AI agents
Sandbox infrastructure for AI agents, with full-environment forks and snapshots across files, processes, memory, and databases.
AI Investor Summary
Indexable is building critical sandbox infrastructure for AI agents, enabling full-environment forks and snapshots for safe development and deployment. Led by a founder with strong engineering experience from Stripe and Google, the company is poised to capture a massive and rapidly expanding market as AI agents move into production. While early in traction, the technical differentiation and market timing present a compelling opportunity.
Key Highlights
- ● Exceptional founder pedigree with Stripe and Google experience.
- ● Addressing a critical and rapidly growing market need for AI agent infrastructure.
- ● Technically differentiated product with strong defensibility potential.
- ● Excellent timing for market entry as AI agents mature.
Risk Factors
- ● Early stage with no significant revenue or user traction yet.
- ● Team size is small, and the depth of the other two co-founders is unknown.
- ● Execution risk in building complex, scalable sandbox infrastructure.
- ● Potential for rapid evolution of AI agent technology to shift infrastructure needs.
Founders
Andrew Gazelka is the co-founder and CEO of Indexable, a Y Combinator startup focused on making data accessible and actionable for developers. Prior to Indexable, he held engineering roles at prominent tech companies, where he gained significant experience in building scalable data infrastructure. His expertise lies in developer tools and data accessibility.
Score Breakdown
Andrew Gazelka has a strong pedigree with engineering roles at Stripe and Google, demonstrating significant technical depth and experience in scalable data infrastructure. His background in developer tools and data accessibility is highly relevant. While the team size is small (3), the founder's experience is a significant positive. We'd want to understand the other two co-founders' backgrounds more deeply. [Boost +1: Founder from Google]
The market for AI agent infrastructure is enormous and rapidly growing. The timing is excellent as AI agents are moving from research to production, and the need for robust sandboxing and environment management is becoming critical. The TAM is potentially vast, encompassing any organization developing or deploying AI agents. Regulatory tailwinds are likely to favor secure and controlled AI development.

The concept of full-environment forks and snapshots across files, processes, memory, and databases for AI agent sandboxing is technically differentiated and addresses a critical pain point. This offers strong defensibility. The UX quality is unknown at this stage, and the platform potential is high if they can build a robust and scalable solution. The core technical challenge is significant and attractive.
As a Spring 2026 YC batch company, traction is expected to be very early. The 'Agent-Readiness Sprint: Building Indexable in Public' blog post suggests active development and community engagement, which is positive for early-stage signal. However, concrete revenue or user metrics are not yet available, making this a weak point at this evaluation stage. [Boost +2: Tier-1 VC: accel]
