Who are Sierra's decision-makers?

Bret Taylor co-founded Sierra after his tenure as co-CEO of Salesforce alongside Marc Benioff ended in January 2023. The origin story is notable: LinkedIn founder Reid Hoffman had introduced Taylor to early previews of GPT-4 in 2022, convincing him that large language models would reshape enterprise software. Weeks after leaving Salesforce, Taylor met Clay Bavor at a Mediterranean restaurant in Palo Alto, and the two agreed to start a company by the end of the meal — before deciding on a specific product. Before Salesforce, Taylor founded Quip (acquired by Salesforce in 2016 for approximately $750M), served as CTO of Facebook, and is widely credited as co-creator of Google Maps. He currently serves as Chair of OpenAI's board.

Clay Bavor spent 18 years at Google before co-founding Sierra. He led Google Labs, directed AR/VR initiatives including Project Starline, oversaw Google Lens, and was responsible for Google Workspace's product and design teams. His product-depth and platform-thinking background complements Taylor's enterprise go-to-market expertise. Together they launched publicly in February 2024 with their first four enterprise customers and $110M in seed funding from Sequoia and Benchmark.

At ~500 employees and scaling fast, Sierra's buying decisions are still relatively centralized. For technology vendors, the CTO and infrastructure engineering leadership in San Francisco own cloud infrastructure, security, and observability budgets. Finance and legal own compliance, contracts, and FP&A tooling. The company's requirements for ISO 27001 and ISO 42001 certification, SOC 2, and enterprise-grade security (PII auto-masking, mTLS) mean procurement for security vendors involves both engineering and legal.

The Field Operations function under Eyken-Sluyters is rapidly scaling, which creates near-term buying decisions for CRM, sales engagement, and revenue intelligence platforms. For strategic partnerships — BPO firms, system integrators, channel — decisions flow through Eyken-Sluyters and likely require Taylor's sign-off given deal size. Vendors who can align proposals to Sierra's fundraising tranches or board cadence (calendar-year budget cycles are most likely) have a structural advantage. Sierra's verified email format is {first}@sierra.ai, used by 81.4% of employees.

Sierra has announced plans to triple its headcount from ~500 to ~1,500 employees, with growth concentrated in engineering, field sales, and international offices. The 300,000 sq ft lease at 185 Berry Street in San Francisco's China Basin is designed to accommodate this expansion. International offices in London, Paris, Madrid, Singapore, Tokyo, Sydney, Atlanta, New York, and Toronto reflect a matrix of geo-based field teams under Eyken-Sluyters. Three acquisitions in early 2026 — Receptive AI (voice), Opera Tech (Japan enterprise AI), and Fragment (Paris AI ops) — have also embedded engineering talent and local market expertise in key international hubs.

Product and engineering remain centralized in San Francisco. The company's open-source SDKs (iOS, Android, React Native at github.com/sierra-inc) and job postings requiring React, TypeScript, and Go suggest a centralized platform team separate from customer-facing delivery teams. Sierra University, the company's enterprise training program, deepens platform stickiness and creates a repeatable onboarding motion as the customer base expands beyond 100 logos.
