Fastbase

Fastbase is a web and database analytics company that offers a growing suite of tools to support B2B marketing and sales. Fastbase was founded in 2014 and in June 2016 Fastbase launched Fastbase WebLeads which is an add-on to Google Analytics that identifies companies that visit your website. Fastbase WebLeads is a web visitor tracking tool for Google Analytics which enables you to discover the companies and organizations that are showing interest in your business, the information they’re searching for, and the pages they’ve viewed. Combining benchmarking data and built-in web leads monitoring the Fastbase SaaS application gives a true understanding of digital audiences. It is straightforward to register and start using Fastbase WebLeads by signing in with a Google analytics account and agreeing that Fastbase can access the Google analytics data. The first time in the Fastbase application, Fastbase retrieves the leads from your analytics account and then starts to process them. The main menu offers a search for leads and a location filter. The main views are: - Stats - New leads - Webleads - Hot leads - Google Ads leads - Show Map The ‘Stats’ option is really useful for getting a snapshot of recent activity - showing the most active visitors and their segmentation by industry and country, although using the ‘Map’ option is also a useful way to instantly see where your web visitors are based world-wide. Most of the options are self-explanatory. Fastbase WebLeads is intended B2B lead generation. You can create filters (visitors from a specific country, visitors who viewed a certain page etc.) and export to excel and Google sheets.

Fix My Speakers

Fix My Speakers is a browser-based tool that cleans mobile device speakers by using sound frequencies between 120 and 420 Hz to dislodge water, dust, lint, and earwax. It operates via the Web Audio API, requiring no downloads or accounts, and works on devices like iPhone, Android, Samsung, and Xiaomi. The tool offers four modes: Water Eject Mode for general water removal, Deep Vibration Mode for stubborn blockages, Gentle Clean Mode for light dust, and Ear Speaker Cleaner Mode for smaller speakers. Each 30-second cycle stops automatically and can be repeated. A sound test feature checks speaker functionality across treble, bass, and voice ranges. Similar to the Apple Watch Water Lock, it uses sound vibrations instead of heat or pressure and cannot repair physical damage or severe water exposure.

Knownly

Knownly is a website visitor identification tool built for small and mid-sized B2B companies that want to know which companies are researching their website. Most visitor identification and sales intelligence tools are priced and built for large sales organizations. Knownly is designed for teams of roughly 10 to 200 employees who want a straightforward answer to who is visiting their site, without a long setup process or a new platform to learn. The product works by matching anonymous website traffic to real companies. After a single JavaScript snippet is added to a website, every page view is checked against IP intelligence data. Knownly filters out traffic from consumer internet providers, hosting and cloud providers, VPNs, proxies, and known bots, so what remains is genuine business traffic. Knownly identifies companies only, never individual visitors. No cookies, fingerprinting, or browser storage are used in the process. Identified companies appear on a dashboard showing visit trends over time, the countries visitors are coming from, and the most active companies from the past week. Each company is assigned an intent score from 0 to 100 based on recency, how many pages they viewed, how often they returned, and how much of the site they explored, grouped into Hot, Warm, and Cool bands so marketing and sales teams can prioritize follow-up. A dedicated company detail page shows a session timeline, first seen and last seen dates, and firmographic details like domain, country, city, and network. The companies database is fully searchable and filterable by name, country, intent band, and status, with CSV export for teams that want to bring the data into a CRM or spreadsheet. This makes Knownly useful for account-based marketing, sales prioritization, and measuring which campaigns or content are actually generating interest from real target accounts, rather than anonymous traffic numbers. Knownly is a Swiss company and takes a privacy-conscious approach: it identifies the company behind a visit, never the person, and does not rely on cookies or fingerprinting to do so.

With LeadCollect, teams can: • Identify anonymous B2B website visitors based on firmographic data • Trigger automated postal mailings based on page visits, intent signals, or abandoned actions • Send personalized letters and print assets at scale without manual effort • Combine online intent with offline impact to increase response rates • Integrate with CRM and marketing systems for end-to-end pipeline tracking LeadCollect bridges the gap between digital intent and physical outreach, making it especially effective for high-value B2B sales, account-based marketing, and conversion recovery where email alone is not enough.
