Partner with brilliant, deeply technical founders with unreasonable ambition, currently focused on AI, robotics, autonomous scientific discovery, and neurotechnology. Named for topological dimension reduction: distilling intricate webs of information into the key insights that drive high-conviction, long-term partnerships.

Exclusion Criteria

Selective by design; avoids founders without deep technical conviction or a genuine, curiosity-driven 'why'.

Topology Research

Investment Thesis

Topology (Topology Ventures) is a solo-GP, early-stage venture firm founded by Casey Caruso in 2024, dedicated to "frontier technology" — the kind of technical bets Caruso describes as making "science fiction reality." The firm's name is drawn from topological dimension reduction, a mathematical/ML technique for distilling high-dimensional data into essential features, which the firm uses as a metaphor for its own process: pulling signal out of a dense, technical landscape to make high-conviction, concentrated bets. The firm is currently focused on four verticals: AI, robotics, autonomous scientific discovery, and neurotechnology, with a demonstrated tilt toward AI infrastructure and decentralized/crypto-AI systems in its actual portfolio.

Stage Focus

Topology invests at the earliest stages — pre-seed and seed — writing initial checks and reserving capital for follow-on. Public reporting (Superscout) explicitly places the firm in the pre-seed SaaS/AI investor category, and its two most-cited 2026 deals (Mio at pre-seed, Inference.net at seed) confirm this.

Check Size

No official check-size range is published on the firm's site. Inferred from disclosed rounds: Topology has participated in rounds as small as a ~$2.2M pre-seed (Mio, co-lead) up to a $20M multi-party seed/launch round (Minerva) and an $11.8M seed (Inference.net, participant alongside Multicoin Capital and a16z CSX). This suggests a flexible early check, likely in the low hundreds-of-thousands to a few million dollars, with occasional co-lead participation. Confidence on an exact range is low.

Lead Tendency

Mixed. Topology co-led Mio's pre-seed round (alongside Fabric Ventures) but was one of several participants (not the lead) in Inference.net's seed and Minerva's $20M raise. This points to a "both" lead tendency — willing to anchor smaller pre-seed rounds but typically joining larger syndicates at seed.

Recent Activity

Topology closed an oversubscribed $75M debut fund (Fund I) in December 2024, reportedly raised in about eight months — notable for a solo-GP, woman-led fund (Venture Capital Journal, Feb 2025). The firm has continued deploying through 2025 and 2026:

  • October 2025: Participated in Inference.net's $11.8M seed round (led by Multicoin Capital and a16z CSX).
  • June 2026: Participated in Minerva's $20M public launch round (with The General Partnership, 8VC, Lingotto Innovation, NBA Investments), alongside a research collaboration with OpenAI.
  • July 2026: Co-led Mio's ~$2.2M pre-seed round (with Fabric Ventures).

Third-party trackers (Tracxn, PitchBook) describe Topology as an active investor with roughly 6-7 disclosed investments as of mid-2026, several within the trailing 12 months, consistent with "actively deploying" fund status.

Portfolio Highlights

Disclosed portfolio companies span AI infrastructure, crypto-native AI, consumer AI, and applied/vertical AI:

  • MyShell — platform for building and using AI-native consumer apps.
  • Ritual — sovereign execution/compute layer for autonomous AI agents on-chain (raised $25M seed led by Archetype).
  • Vana — open, user-owned data infrastructure protocol for training human-grounded AI.
  • Inference.net — open-source AI inference/hosting provider for custom language models.
  • Minerva — agentic AI platform for consumer marketing, built in partnership with OpenAI; raised $20M at public launch.
  • Mio — AI coworker embedded in Slack; raised pre-seed backed by Fabric Ventures and Topology.

No exits or acquisitions have been publicly reported for the portfolio as of this research.

Team

  • Casey Caruso, Founder & Managing Partner — previously an investment partner at Paradigm, an advisor/investor role at Bessemer Venture Partners, and an engineer on Google's research systems team. Harvard-educated; based in San Francisco. Solo GP running Topology.
  • Hunter Harloff, Research — previously at Citadel.
  • Austin Echtenkamp, Operations & Finance — previously at Coinbase.

Decision Process

Solo GP structure — Casey Caruso is the sole general partner and final decision-maker. Harloff and Echtenkamp support research and operations/finance respectively but are not listed as investing partners.

Founder Preferences

Topology's site frames its ideal founders as "brilliant technologists" with "unreasonable ambition," selected through a highly selective process. The firm's three stated principles — "Execute with Vision" (imagination plus calculated execution), "Self Author" (founders who take ownership of their own vision rather than deferring to others), and "Lead with Curiosity" (a genuine, technical "why") — suggest a strong preference for deeply technical, conviction-driven founders over commercially-polished but less technical operators.

Geographic Focus

Headquartered in San Francisco, CA (per LinkedIn and multiple press reports; note some third-party databases such as PitchBook list a Miami Beach address, which may reflect a registered-agent or fund-admin address rather than the operating office). No explicit geographic restriction is stated; portfolio companies span both US-based and crypto-native/globally distributed teams.

Public Goods / Research Output

Beyond investing, Topology publishes several public research artifacts that double as deal-sourcing and thesis-signaling tools: a Neuro Map (interactive atlas of the neurotechnology/BCI landscape), a Scientific AI Map (market map of AI-for-science tooling), a Robotics Map (map of the embodied-AI/robotics ecosystem), and LatentZip, an open-source compression algorithm using latent-space representations for high-ratio natural-language compression. These reinforce the firm's stated focus areas (AI, robotics, autonomous discovery, neurotech) and its self-positioning as a technically credible, research-driven fund rather than a purely capital-allocating one.

Backers

Topology's Fund I is backed by Marc Andreessen, a cofounder of OpenAI, and a founding member of Anthropic, per the firm's own site — notable frontier-AI-adjacent LP names for a debut, solo-GP fund.
