Company profile

researched Aug 2026

Arkestro develops a "predictive procurement" software platform for enterprise procurement and sourcing teams. Rather than waiting on supplier quotes, the platform generates predicted pricing and recommendations so buyers can set an opening price, then runs multi-supplier, multi-round sourcing events with automated workflows. The company describes its technology as patented and built on three disciplines it calls Negotiation Science (fact-based pricing and terms strategies), Supplier Science (AI-assisted supplier selection and engagement) and Process Science (workflow automation to shorten procurement cycles), combined with AI and game theory.

The platform is positioned for large enterprises with complex, high-volume spend, including manufacturing, automotive, construction materials, chemicals, energy and real estate services. Arkestro publishes customer-reported outcomes such as average savings of 18.8% across spend categories, 60% faster cycle times, and 3x increases in spend influence without added headcount, along with case-level figures including 34% average savings per event at a US automotive manufacturer, $12M in savings for a global engineering solutions company, and 92% average supplier participation at a US construction materials manufacturer. Named customers and references include Chevron, Valvoline, Koch's KES business, GoGo squeeZ (Materne North America), Provisur, Dover Chemical, BMI, JLL and Trinity Industries.

Alongside product, Arkestro runs a customer and industry conference, Optimal, held in Houston, Texas; Optimal '25 drew more than 400 attendees and Optimal '26 is scheduled for October 13-15 in Houston. The company also maintains an executive advisory board of supply chain and procurement leaders.

Business model

Arkestro sells its predictive procurement platform to enterprise customers, positioning it as an addition to existing procurement operations that scales the amount of spend a team can influence. Deployment is presented as fast, with customers said to see impact within their first 60 days and results in as little as two months.

Traction

As of December 2025, Arkestro reported that its platform had been fueled by $410 billion in spend across thousands of suppliers and had facilitated the quoting of more than 400,000 items. 2025 customer wins announced included Chevron and Valvoline. Optimal '25 in Houston was the company's largest event to date with more than 400 attendees.

Latest developments

In December 2025 Arkestro announced cross-industry customer momentum for the year, including new enterprise customers such as Valvoline, a strategic partnership with BDO, a Capgemini go-to-market partnership, and a $36 million strategic investment led by Aramco Ventures and Altira Group. It also expanded its executive advisory board with Paul Wellener, former Vice Chair at Deloitte, and Robert Turnham, former President and board member at Goodrich Petroleum, and separately announced the appointment of Tom Aitchison as President. In 2026 the company announced that its Director of Supply Chain Innovation and Supplier Ecosystem, Tahmeeda Bushra Khorasani, was named a winner of the 2026 Women in Supply Chain Award.
