Kindred Ventures
Kindred Ventures is a San Francisco-based, earliest-stage venture capital firm founded in 2014 by Steve Jang and led today as a partnership with Managing Partners Steve Jang and Kanyi Maqubela. The firm backs visionary and relentless founders building the future with technology and science, investing primarily at the pre-seed and seed stage and often partnering with entrepreneurs before a company is even formed.

With around $600M in assets under management, notable investments and exits include Uber, Coinbase, Poshmark, Reddit, Postmates, Blue Bottle Coffee, Perplexity, Tala, Magic Eden, dYdX, and PlayAI (acquired by Meta in 2025).

Cohort brief
Auto-generatedThe 112 portfolio companies with APIs in the catalog, backed by Kindred Ventures, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Access Clarity | 25.3 | 22.3 | +3 | 112 |
| Developer Ergonomics | 19.1 | 17.9 | +1.2 | 112 |

| Contract Quality | 16.5 | 17.5 | -1 | 112 |
| Operational Transparency | 9.1 | 11.3 | -2.2 | 112 |
A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
