Slope.io

What Slope.io does

Slope.io, Inc. is a private, venture-backed healthcare software company that provides a cloud-based biospecimen lifecycle management platform called Biospecimen360™ for clinical trials. The platform orchestrates lab kits, biospecimens, and sample metadata across the three critical phases of a trial — before collection (lab kit management and resupply), during collection (guided sample workflows with protocol compliance), and after collection (shipment coordination and metadata transfer) — connecting clinical research sites, pharmaceutical and biotech sponsors, CROs, central and specialty labs, couriers, and clinical systems (EDC, RTSM, LIMS) through a single vendor-agnostic software layer. The platform is built for compliance with SOC 2, GDPR, 21 CFR Part 11, ICH E6(R3), ALCOA+, and Annex 11 standards, and is supported by a professional services offering for implementation and optimization.

The company operates a hybrid go-to-market model: research sites access the platform for free through self-serve signup, while pharmaceutical sponsors and biotech companies pay for enterprise subscriptions, generating a two-sided network where 2,200+ sites across 23+ countries have independently adopted the solution, including 83% of NCI-designated cancer centers. Sponsors benefit from a reported 98% site adoption rate on contracted trials — an unusual outcome in clinical technology — and quantified outcomes including 71% average lab kit waste reduction and up to 98% reduction in sample queries. Strategic channel partnerships with LabConnect (bidirectional LIMS API integration, launched November 2024) and CellCarta (Kit Inventory Portal formalized February 2026) extend distribution into the lab services ecosystem.

Founded in 2016-2017 and headquartered in Norfolk, Virginia (legal) with operational presence in San Francisco, Slope has raised approximately $23 million+ in disclosed funding across multiple rounds, including a $20 million Series A in October 2021 led by NEA with participation from 645 Ventures, Eniac Ventures, Electric Ant, and Wormhole Capital, followed by an August 2024 round led by Alumni Ventures with NEA participation. The company is led by co-founder and CEO Rust Felix, supported by an executive team including CPTO Jim Munz, CRO Ben Carmel, COO Terry Edwards, CCO Hope Meely, and CHRO Susan Seymore. In 2022 Slope was named a Sample Vendor in the Gartner Hype Cycle for Life Science Clinical Development in the Clinical Trial Resource Management category.
