Save time, stay compliant and save money while creating the best leave experience for your employees. Tilt is a third-party leave administration software built with our own proprietary technology and automation, backed by leave law experts, software engineers, and Leave Success Managers that blend software and the human touch. The problem is that you’re overworked, unsure, and unsupported. The average leave takes 25 hours to manually manage, and getting it wrong can mean lawsuits which can end up costing nearly $78,000. You want a smoother process and assurance that you’re legally compliant, but: you don’t have the bandwidth, time, budget, or expertise, and great dedicated leave management that works is hard to find. Confusing spreadsheets, random email chains or not offering anything are just temporary fixes that end up costing your company thousands of dollars each year while you and your employees are left feeling lost. You need a solution that will scale for you and with you. That’s why Tilt was created. To make leave NOT suck. Sparked by one too many unjust leave experiences, our Founder and CEO Jen Henderson has been leading this charge since 2017 because she knew there had to be a better way. And it’s here. With streamlined processes, an HR dashboard, employee views, compliance and management for all leave types, HRIS integration, payroll calculations, and a dedicated Tilter for you and your employee to offer support through the entire journey. Tilt will save you time, money, and undue stress. When an employee requests a leave, we’ll automatically determine eligibility, create custom step-by-step instructions, track FMLA usage along with any other time they quality for, calculate their payroll, and put in all in one place for you and them to see. Finally, have time to be there for your people and help your company thrive, but for a price you can invest in. Book some time to chat with us. https://hellotilt.com/

Launched in 2011, Estimize is an open financial estimates platform designed to collect forward looking financial estimates from independent, buy-side, and sell-side analysts, along with those of private investors and academics. By sourcing estimates from a diverse community of individuals, Estimize provides a more accurate, more timely, and more representative view of expectations compared to sell side only data sets which suffer from several severe biases. Currently, 100,000+ analysts contribute to Estimize, resulting in coverage on over 2,200 stocks and 80 economic indicators each quarter. The Estimize consensus has proven more accurate than comparable sell side data sets over 70% of the time and by 15% on average. Contributors to the Estimize platform receive free access to view our data in return for their honest pseudonymous contributions. Estimize manages the honesty and quality of contributions via several machine learning algos and behavioral models, along with a human layer of review (human brains are still useful!). Estimize scores and ranks analysts, providing them with an easy way to store, benchmark, and measure their own accuracy. Estimize represents the market’s true consensus, with our data regularly referenced in notable financial media sources such as Bloomberg, The Wall Street Journal, CNN Money, The Street, Forbes, Barron’s, Investors Business Daily and Business Week, amongst others. Our clients include institutional managers running fully systematic quantitative strategies, fundamental managers running quantamental, long/short, and long only strategies, as well as macro investors and vol traders. Our data sets and factor models can be purchased via our real time API/FTP, or our front end platform which includes advanced analytics, screening tools, and emails. In 2021, Estimize merged with alternative data provider ExtractAlpha.
