What Yendou does

Yendou GmbH is a Berlin-based, venture-backed SaaS company founded in 2022 that operates an agentic clinical operations platform for mid-cap contract research organisations (CROs). Its core offering is a six-module system — RFI, Country & Site ID, Contracting, Feasibility, Site Engagement, and Memory — that automates the pre- and post-award workflow between sponsor Request for Information and First Patient In. The platform is built on the Yendou Site Graph, a proprietary directory of 22,332 investigators, 13,478 research sites, and 115 site networks spanning 79 countries and 23+ therapeutic areas. AI agents read sponsor RFI documents, draft answers from the CRO's institutional record, pre-fill feasibility surveys to roughly 85% completion, manage CDA/CTA lifecycles via browser-based workflows with no site login, and surface next-best-actions from accumulated engagement history. Customer data is never used to train AI models, and the platform runs on Microsoft Azure with sub-processors including OpenAI and Anthropic.

The product is monetised as an enterprise SaaS subscription with quote-based annual pricing sold through a direct field-sales motion anchored by 'RFP walkthrough' demos targeting CCOs, VPs of Business Development, and CEOs of mid-cap CROs. GTM is concentrated on enterprise bid-defence use cases, with five published case studies showing measurable outcomes: a global mid-cap CRO lifting win rate from 15% to 21% in six months, a Phase III oncology study achieving First-Patient-In nine weeks earlier, and a small-cap CRO winning a €3.2M pediatric oncology bid in 90 days in a therapeutic area it had declined for eleven years. Distribution is direct, with Lindus Health (next-gen CRO) positioned as the inaugural partner and reference account; a Delaware C-corp subsidiary supports North American contracting. Compliance posture — 21 CFR Part 11, GDPR, ISO 27001, and SOC 2 Type II in progress — is explicitly architected for CRO procurement gates. As of the most recent disclosure, Yendou had raised a $1.3M pre-seed round led by b2venture (February 2024), operated with approximately 11 team members, and processed 6,594 site selection decisions growing 28% month-over-month.

Core offering

Yendou is an agentic AI SaaS platform that automates pre- and post-award clinical trial workflows for mid-cap Contract Research Organizations (CROs). The platform captures and structures every RFI (Request for Information), CDA (Confidential Disclosure Agreement), feasibility survey, and CTA, then surfaces this structured intelligence to help CROs win enterprise bids and accelerate First-Patient-In timelines. Six integrated modules — RFI, Contracting, Feasibility, Country & Site ID, Site Engagement, and Memory — run on a proprietary Site Graph of 22,332 investigators, 13,478 research sites, 115 site networks across 79 countries and 23+ therapeutic areas, sold as an annual enterprise subscription.

Product overview

Yendou is a clinical operations automation platform built as a modular system of six integrated products for mid-cap CROs. The platform serves as an 'agentic operating layer' for pre-award and post-award activities from RFI to First Patient In. The core modules are: Yendou RFI (RFP response automation), Yendou Country & Site ID (site identification and matching via the Site Graph), Yendou Contracting (CDA/CTA lifecycle management), Yendou Feasibility (survey automation), Yendou Site Engagement (relationship intelligence), and Yendou Memory (organizational knowledge capture). All modules compound on each other—every study starts ahead of the last as feasibility is pre-filled, RFIs are pre-drafted, and CDAs are pre-redlined to the CRO's own patterns. The platform is non-site-facing by design, removing administrative load from sites without requiring them to adopt new portals or logins.

Functional benefit

Products and services

• Yendou RFI Agentic workflow module that takes a sponsor's RFI (.xlsx or .docx) and pre-fills every answer from the CRO's own institutional record. AI agents read every question, draft each answer, score their confidence, and route gaps to the function that owns them, compressing what previously took a full day of Excel into a response before lunch.
• Yendou Contracting Contracting module that consolidates CDA and CTA lifecycle management into one screen. Enables bulk-sending to all sites in a study, browser-based redlining without account creation, eIDAS-compliant electronic signing via DocuSign and Adobe Sign, timestamped rounds, and audit-ready signatures, reducing site CDA cycles from nine days to four.
• Yendou Feasibility Feasibility survey automation module that pre-fills ~85% of surveys with what sites already told Yendou in previous studies. Sites confirm or correct responses via a browser link with no login or portal required, and new answers auto-save to the CRO's record — cutting site follow-ups by up to 100% and recovering roughly eight hours per person per week.
• Yendou Country & Site ID Site identification and matching module providing a 22,332-investigator footprint across 79 countries and 23+ therapeutic areas, available on day one of any new therapeutic area. Cross-references protocol parameters against the team's own engagement history to rank and recommend investigators and sites.
• Yendou Site Engagement Relationship intelligence module that captures every message to and from a site and surfaces the whole relationship history (every study, how the relationship is actually doing, who has gone quiet, who is overdue). Surfaces next-best-actions so teams move tasks forward without leaving the inbox or switching tabs.
• Yendou Memory Organisational intelligence module that captures every RFI answer, CDA cycle, feasibility reply, site signal, and decision as structured, queryable intelligence — queryable by indication, country, sponsor, and year. Ensures institutional knowledge compounds across studies and survives staff turnover, owned by the CRO forever.

Broad incumbents

• Veeva Systems: Public enterprise cloud provider for life sciences with Vault CTMS, eTMF and clinical operations suite. Competes with Yendou's contracting and feasibility layers, but serves pharma sponsors and large CROs with a much broader portfolio; Yendou already lists Veeva Vault as an integration partner.
• Medidata (Dassault Systèmes): Industry-leading eClinical suite (Rave EDC, CTMS, eCOA, RTSM) used across most large CROs and sponsors. Competes broadly across Yendou's modules as part of a much wider platform, with deep enterprise penetration that Yendou must displace or sit alongside.
• Oracle Health Sciences (Siebel CTMS): Legacy CTMS and clinical trial platform from Oracle, widely deployed at large CROs and pharma. Overlaps with Yendou's site/feasibility workflows as part of a broader trial management portfolio, typically sold to enterprise clinical operations teams.
• Signant Health: Clinical trial technology provider offering eCOA, ePRO, patient engagement and rater training, with broad sponsor/CRO coverage. Comparable on the patient- and site-engagement side of Yendou's offering, but operating as a multi-product incumbent rather than a CRO-first platform.
• Clinical Ink: Decentralized trial and eCOA/ePRO platform for CROs and sponsors. Overlaps with Yendou's site engagement, patient workflows and clinical operations modules as part of a broader DCT portfolio with established enterprise customers.

Emerging players

• Castor: eClinical platform offering EDC, ePRO, eConsent and DCT tools to CROs and sponsors. Overlaps with Yendou on feasibility, site activation workflows and CRO enablement, but with a sponsor-leaning, decentralized-trial focus rather than a pre-award bid-defence focus.
• Florence Healthcare: Site-focused eRegulatory and document management platform for clinical trials, widely used by CROs and sites. Directly comparable to Yendou's site engagement and document/contracting layers, with overlapping buyer (clinical operations leaders at CROs).
• Vial: Tech-enabled CRO providing next-generation clinical trial execution for sponsors. Comparable to Yendou's CRO buyer persona and adjacent to its CRO-tech tooling, although Vial executes trials itself while Yendou sells software to similar CROs.
• Medrio: Cloud-based EDC and eClinical platform serving CROs and sponsors across study build, data capture and reporting. Comparable to Yendou on CRO-facing clinical operations tooling, but focused on data capture rather than pre-award, site identification, and contracting workflows.

Direct peers

• Lindus Health: Next-generation CRO running tech-enabled clinical trials, named as Yendou's inaugural partner. While primarily a customer relationship, Lindus itself competes in the same CRO market with a tech-forward operating model that overlaps with Yendou's buyer persona and value proposition.
