Bonfire Ventures
Bonfire Ventures is a Los Angeles-based, seed-stage venture capital firm co-founded by Mark Mullen and Jim Andelman that invests exclusively in business-to-business (B2B) software companies, with a current focus on AI-native B2B founders. The firm runs a low-volume, high-conviction, high-support model — backing roughly 10 to 12 new companies a year, leading approximately 95% of the rounds it participates in and taking board seats — and positions itself as "AI-native too," operating an in-house AI system called Bonnie to source and support founders. Bonfire reports more than $18B in cumulative exit value across its history, with notable outcomes including TaxJar (acquired by Stripe), MNTN (IPO), The Trade Desk, Scopely, Moat (acquired by Oracle), and Comparably (acquired by ZoomInfo). It was added to the API Evangelist network as a portfolio company of Foundry Group and enriched from the firm's public site.
Bonfire Ventures has 111 portfolio companies tracked on the APIs.io network, of which 31 (28%) publish APIs indexed here. The remaining 59 are tracked as profiles without a published API on the network.
Its highest-rated API providers on the network are Embrace, ZeroTier, Particle, Cube, Spekit.

Cohort brief
Auto-generatedThe 52 portfolio companies with APIs in the catalog, backed by Bonfire 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 | 36.2 | 26.5 | +9.7 | 52 |
| Developer Ergonomics | 26.4 | 23.8 | +2.6 | 52 |
| Operational Transparency | 15 | 13.2 | +1.8 | 52 |
| Discoverability | 58.6 | 58 | +0.6 | 52 |
| Contract Governance | 5.3 | 7 | -1.7 | 52 |
| Contract Quality | 15.9 | 17.7 | -1.8 | 52 |
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.
| Artifact | This cohort | Catalog | Difference |
|---|---|---|---|
| MCP server (any) | 15% | 15% | 0 |
| MCP server (first-party) | 15% | 13% | +2 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 11% | 12% | -1 |

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.

Coverage caveat. 48 of 52 scored members had under half their catalog-attributable points satisfied at all (catalog_earned / catalog_max < 0.5). They are INCLUDED in the mean above. A large share here means the cohort mean is partly a measurement of how far our enrichment reached, not only of how these providers publish.Generated from the catalog build of 2 November 2026, across 37080 providers, using the same computation served by the APIs.io cohort API. Briefs are published for rosters of 5 or more scored providers; below that a distribution is not meaningful.
