HoldFast is a video review and presentation platform for small video teams: production companies, post houses, agencies and freelancers. Upload once and share three ways. Review links let clients leave timecoded comments, draw on the frame and approve the exact version they watched. Reels are branded showreel pages at their own address. Presentations turn a PDF, PowerPoint or web deck into one tracked link with per-slide reading analytics. Every link reports who watched, which company and how far they got, with honest wording when a company is only inferred rather than confirmed. Versions are named by their filenames, never invented numbers, and a quiet fix swaps the file behind a link you already sent without changing the address. Reviewers never need an account. Also included: audience testing with real recruited panels, and a Mac app that backs up or moves a Vimeo library. Pricing is a free plan plus flat-rate Pro and Team plans with no per-seat fees.
