Abstract is sector-agnostic. AI sits alongside enterprise software, fintech, health, crypto and consumer in its portfolio.

Messari lists 0G Labs, an AI infrastructure Layer-1 project, as a seed investment in November 2024. WaveUp names Third Dimension AI among 16 new investments in 2024. TipRanks lists Third Dimension AI as an enterprise software and AI seed round. On the Lounge deals desk, Abstract is attached to AI rounds including Volantis (Series A, $88M, led), Harbor (Seed, $10M, led), BuildForever (Seed, $9.5M, led) and Cast Insights (Pre-seed, $4.5M, led). Recent AI rounds it joined without leading include Ghost, Ellis, Sycamore and June AI.
Abstract invests at pre-seed, seed and Series A. The firm does not publish a check size, and third-party estimates conflict. Superscout gives $250K to $2M. VC Sheet gives $100K to $1M. WaveUp gives $5M to $15M, and Private Equity List gives $5M to $10M. Treat these as unverified and ask the firm directly. The Lounge deals desk shows Abstract leading rounds from $4.5M to $88M, which is a different measure from its own check size.
