Value proposition
Fractional AI helps enterprises and PE-backed companies turn AI from an experiment into a competitive advantage by building bespoke gen AI solutions — automating internal processes, building AI-powered products, and solving problems off-the-shelf tools can't handle. Their elite San Francisco engineering team delivers production-grade AI systems that drive measurable results.

Custom AI agent development (API Integration Builder, Voice Agent, Data Structuring Agent, Developer Agent, Information Analysis Agent, Content Moderation Agent); Enterprise AI transformation consulting; Private Equity portfolio AI services; Healthcare and Life Sciences AI division
Unique value
Bespoke gen AI software built by elite San Francisco engineers — bridging the gap from AI in concept to AI in production for enterprises' highest-value projects, with a focus on measurable business outcomes rather than flashy demos.

Technology advantage
Elite applied AI engineering team with deep experience across hundreds of AI projects; End-to-end capability from strategy through implementation; Strong PE/VC relationships (Blackstone, H&F portfolio work); Former OpenAI partner turned Anthropic operational centerpiece; Track record of reducing hallucinations by 80%+ (Zapier case study) and 10x-ing connector build speed (Airbyte)
How they differentiate
Unlike traditional consulting firms that produce slide decks and roadmaps, Fractional AI sends engineers into client operations to rebuild systems around what frontier models can do. They combine deep entrepreneurial experience (founders are repeat founders from LiveRamp) with hands-on engineering delivery, focusing on production-grade systems rather than proofs-of-concept.
