What Senja does
Senja is a London-headquartered (Senja Proof Ltd) SaaS platform, founded in 2022, that enables creators, small businesses, SaaS companies, and agencies to collect, manage, analyze, and display customer testimonials — primarily text and video — across websites, email, and social channels. Its core product is a unified testimonial collection and management platform with a no-code visual Studio for producing Walls of Love, widgets, images, pop-ups, sizzle reels, and video clips; it supports bulk import from 30+ platforms (Shopify, G2, Trustpilot, Yelp, Product Hunt, Udemy, Google reviews) as well as CSV upload and Chrome extension scraping. The underlying stack is Firebase (auth and storage) hosted on Vercel and Railway, with payments via Paddle, analytics via Heap and Pirsch, live chat via Crisp, and a public REST API plus webhook layer. Notable AI-enabled capabilities include auto-transcription of video testimonials, smart sentiment analysis, AI-generated case studies, and a Model Context Protocol (MCP) connector exposing the platform to Claude AI.
The business runs a pure product-led, self-serve go-to-market with no live demos or sales calls — onboarding takes under five minutes, support is async via Loom and monthly Office Hours on Luma, and distribution is organic through content marketing, SEO, a public feedback board (Featurebase), a Chrome extension listing, and an affiliate program. Monetization is freemium subscription: a free tier up to 15 testimonials, plus paid Starter, Pro, and Agency tiers sold monthly or annually (20% annual discount); non-profit discounts are available and seasonal promotions run occasionally. Senja discloses 3,000 paying customers as of January 2026 and a public goal to reach 10,000, while operating with a 3-person fully remote team.
