Spark Capital is a multi-stage venture capital firm founded in 2005 by Paul Conway, Santo Politi, Todd Dagres, and Bijan Sabet, with offices in San Francisco, New York, and Boston. Spark is a generalist firm that partners with founders from seed through growth across consumer internet, enterprise software, artificial intelligence, gaming, crypto, fintech, infrastructure, hardware and semiconductors, life sciences, aerospace, and the future of work. The firm invests from a family of early-stage funds (most recently a $700M fund in 2024) and dedicated growth funds (most recently a $1.4B fund in 2024), and press reports have placed its assets under management in the range of $12-15 billion. Spark first became widely known for leading Twitter's Series B in 2008 and has since backed a run of defining companies including Slack, Discord, Snap, Coinbase, Affirm, Plaid, Cruise, Oculus, Scale AI, Ramp, Deel, and Anthropic, whose Series C investment the firm turned into one of venture's largest recent markups. Spark rebranded in 2020 with design studio Pentagram around its distinctive dog-themed identity, and publishes a curated set of portfolio companies rather than a full list.
Firms are ranked by cumulative portfolio strength — how many highly-rated API companies they've backed, weighted by tier across composite quality and agent-readiness. The averages below are a secondary read on the typical company in the book.
Spark Capital has 48 portfolio companies tracked on the APIs.io network, of which 24 (50%) publish APIs indexed here. The remaining 24 are tracked as profiles without a published API on the network.
Its highest-rated API providers on the network are Anthropic, Plaid, Parallel, Slack, Snap.
Portfolio on the Network
Portfolio companies that publish APIs indexed on APIs.io, grouped by their
API Evangelist rating. Exemplar and Strong are expanded by default.
Exemplar5Complete, well-documented, and agent-ready
The 42 portfolio companies with APIs in the catalog, backed by
Spark Capital, scored on the Kin Score. Every figure below is computed from
the catalog — nothing here is written.
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.

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.
This roster declares 48 members; 43
resolve to a provider in the catalog and 42 carry a score
(98%). The figures above describe the scored members only. Coverage caveat. 32 of 42 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
3 October 2026, across 28834
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.
