About Weaviate
Weaviate is a privately held Data company, incorporated in the Netherlands and headquartered in Amsterdam.
Last reported secondary-market price: $2.83 per share (as of 2026-10-02). Your own 409A may differ.
Vector database.
Equity grants at Weaviate typically include incentive stock options (ISOs) and non-qualified stock options (NSOs).
Bob van Luijt, Etienne Dilocker, and Micha Verhagen founded Weaviate in Amsterdam in 2019 to build a vector database designed natively for machine learning workloads rather than adapted from a relational or document store. Weaviate stores objects alongside their vector embeddings, supports multiple vectorization modules, including OpenAI, Cohere, and Hugging Face integrations, and exposes a GraphQL and REST API. The company raised a $50 million Series B in April 2023 led by Index Ventures, then a further $50 million Series C in October 2025 led by Battery Ventures.

Weaviate NSO exercise creates ordinary income on the bargain element (federal, state, and FICA) at the price on the day you exercise. The calculator works at any valuation, so you can model your exercise cost at the current 409A FMV, an expected IPO price, or post-IPO scenarios.
Example: at Weaviate's last reported price of $2.83, exercising 5,000 NSOs with a $1 strike creates a $9,150 bargain element, taxed as ordinary income on the day you exercise. Combined federal + state + FICA on that bargain typically lands between $2,471 and $4,118 depending on your bracket and state. The calculator above computes the exact figure for your situation and compares selling now vs. holding through the long-term capital-gains threshold.

Weaviate equity questions
- How is a Weaviate NSO exercise taxed?
- Exercising a non-qualified stock option (NSO) creates ordinary income on the bargain element (the price on the day you exercise minus your strike), subject to federal income tax, state income tax, and FICA. The calculator above computes that tax for your Weaviate grant and compares selling the shares now against holding past the one-year mark for long-term capital-gains treatment.
- Does Weaviate grant ISOs, NSOs, or RSUs?
- Equity compensation at Weaviate typically takes the form of incentive stock options (ISOs) and non-qualified stock options (NSOs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise.
- Are Weaviate shares eligible for QSBS?
- They might be. Qualified small business stock (QSBS) under Internal Revenue Code Section 1202 can exclude federal tax on much of the gain when shares were acquired at original issuance from a C-corporation while its gross assets were under $50 million, and held at least five years. Whether your Weaviate shares qualify turns on when you acquired them and the company's asset size at that time.
