Circuit & Chisel
Category: Foundation Models / LLMs
Circuit & Chisel is a frontier AI lab building Unbiased and Pareto, a blended model that delivers frontier-quality intelligence at a fraction of frontier cost; the company previously launched ATXP for agentic payments. Circuit & Chisel was founded in 2025. The company is led by Louis Amira. Based in Fairfield, CT, USA. Team size: 2-10. Total funding raised: $19.2 million. Latest round: Seed. Key investors include Primary Venture Partners, ParaFi Capital, Stripe, Coinbase Ventures, Solana Ventures, Samsung Next, Polygon Labs.

Value proposition
To increase access to AI by reducing the cost of frontier intelligence via Pareto, a blended model that composites frontier and open models for frontier-quality results at ~75% lower cost.
Products and solutions
Unbiased (platform), Pareto 26.8 (blended frontier model), ATXP (Agent Transaction Protocol), ATXP Chat, ATXP Pics, ATXP Music
Unique value
Pareto blends multiple frontier and open models in parallel (not a router) to hit frontier benchmark scores at ~$0.10 mean cost per task—about 75% less than comparable frontier models—via the Unbiased platform.
Target customer
Developers and businesses seeking frontier-quality LLM inference at lower cost via Unbiased/Pareto; historically also builders of AI agents needing agentic payment rails (ATXP).
Industries served
Foundation Models / LLMs, AI Infrastructure, Agentic Commerce
Technology advantage
Pareto composites multiple LLMs in parallel and synthesizes results (vs single-model routing), preserving prompt caching and delivering frontier composite scores at ~12.5–15% of top frontier per-token prices. Prior ATXP stack enabled on-chain auditable agent micropayments without long-lived API keys.
How they differentiate
As a frontier AI lab, Circuit & Chisel differentiates via Pareto's parallel multi-model blend that matches frontier quality at materially lower cost, rather than training a single proprietary frontier model or using naive routing. ATXP remains a prior protocol play for agentic commerce.

Major milestones
Secured $19.2 million in seed funding (Sep 2025)., Launched ATXP for agentic payments., Topped x402 and MPP leaderboards with ATXP Chat/Pics/Music (Apr 2026)., Surpassed 1 million ATXP accounts (Jun 2026)., Launched Unbiased platform and Pareto 26.8 public beta as frontier AI lab (Aug 2026).
Growth metrics
ATXP surpassed 1M accounts (Jun 2026); led MPP (~$44.7K vol / 132.9K txns / 45.4K active agents) and x402 (~$116.7K vol / 310.5K txns / 113K buyers) over prior 30 days. Pareto 26.8 in public beta with a few dozen private-beta customers; platform.unbiased.ai live Aug 2026.
Market positioning
Positions as a frontier AI lab focused on cheaper frontier intelligence (Unbiased/Pareto), evolving from its ATXP agentic-payments infrastructure origins backed by Stripe, Primary, and ParaFi.
Geographic focus
While the company is based in New York, their protocol, ATXP, is designed to be a 'web-wide' standard, indicating a global focus rather than a specific geographic market.
