Venture Capital

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.

Cohort brief

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.

This roster declares 90 members; 88 resolve to a provider in the catalog and 52 carry a score (59%). The figures above describe the scored members only.
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.
