Whatever you do - DO NOT sign up to Lead Forensics. We used this for around 5 months and then got absolutely no business from it what so ever. We then asked to get out of the 'contract' which was supposedly for 12 months. We were told that we are in contract until November - another 11 months as they gave us 3 months free. So £400 per month for 11 months = £4,400 when we told them repeatedly that the reverse IP tracking is not working for us. When you want to cancel they get their 'cancellations' team to try and persuade you that the last 5 months were just an anomaly and that the system really does work - LIES. Just like when you try to cancel car insurance you get through to that annoying department to try to tell a business owner that this software will work, when i have 5 months and £2,000 spent previously that it is not suitable for us and we want out. If they would have cancelled the contract then, this review would not have happened. What you get from Lead Forensics is reverse IP tracking showing some of the big companies in the UK and Worldwide. OK that's great, but try and get through to the decision makers! You can't. Moreover the issues of it not working for us, the massive issue is that we repeatedly told them that we want OUT of the 'contract' as we had spent £2,000 on their service with absolutely NO return on investment. Whatever you do, do NOT sign up to these crooks. If it doesn't work, you are stuck with it. We now have had court letters as i refused to pay and now we are going down the legal route. Again, my advice is do not use them. There are many other reverse IP tracking companies out there who offer NO contracts, of which i wish i had done my research. You have been warned.
