Sizle

Sizle is a document sharing and tracking platform, based in Europe, that positions itself as a document CRM for sales and fundraising teams. It addresses a blind spot in many sales processes: once a proposal, pitch deck or report is sent as an attachment, the sender has no insight into whether it was opened, which pages were read or who else it was forwarded to, and sensitive files can circulate without control. Sizle’s approach is to replace attachments with secure, trackable links, capturing engagement data and viewer information that indicates buying interest. This data is then organised in a way that helps teams prioritise follow-up, identify promising leads and refine their content, turning shared documents into a measurable part of the pipeline.

Key features include page-by-page analytics showing time spent and completion, real-time notifications when documents are viewed, lead capture forms that collect viewer details before access, and visitor identification. Security controls cover password protection, email verification, expiry dates, download restrictions and watermarking, while virtual data rooms support due diligence and investor relations. Sizle also provides content management tools for organising and updating documents centrally, so that a single link always displays the latest version, and it includes features for editing and improving documents, such as automated summaries and suggestions. Branding options allow shared pages to reflect the organisation’s identity. The platform integrates with CRM and productivity tools including HubSpot, Salesforce, Google Drive and Zapier, allowing engagement data to feed existing sales workflows. Sizle is delivered as a cloud service accessible in the browser and is aimed at sales teams, start-up founders raising capital, agencies, consultants and marketing teams that rely on documents to win business. Its combination of tracking and security suits organisations sharing confidential material externally. Pricing starts from around USD 29 per month with a free trial, and a free version is also available.
