Frizzle uses AI to grade handwritten math assignments for teachers and transform them into rich analytics and differentiated assessment to help personalize instruction for every student. Teachers spend over 10 hours a week or 25% of all their work grading - Frizzle does it in minutes. Frizzle is the most valuable piece of software for teachers ever, as it eliminates the most time-consuming part of their workflow so they can focus on teaching. Frizzle shifts education from waterfall to agile learning. Instead of waiting for end-of-unit tests to discover gaps, teachers get continuous, real-time insight into student thinking from everyday work. Feedback becomes immediate, instruction adapts weekly, and learning iterates (measure, adjust, improve) so every student progresses faster with less teacher burnout. Frizzle was named an official White House AI Education Partner alongside OpenAI and Meta: https://www.whitehouse.gov/edai/. Frizzle was co-founded by Abhay Gupta and Shyam Sai, who met in high school over 10 years ago.

We have B2B company data on 40 million B2B companies and 850 million B2B contacts (i.e. B2B database), sourced from dozens of data providers (i.e. think sources like BuiltWith, Crunchbase, LinkedIn, ZoomInfo, SemRush, Apollo data, and more). This allows you to precisely segment your audience by the companies you care about and exclude everyone else. Our audiences are dynamic (i.e., account based marketing, account based sales, ABM like Clearbit, 6sense, Demandbase), meaning we continuously look for prospects matching your targeting criteria and add them to your audience to run automated outbound sales sequences. This automates manual workflows you might be running on platforms like Clay or Persana. You can also create an audience once based on intent signals (i.e., GTM or go-to-market signals, sales intelligence) and put your outreach on autopilot. This is why RevOps, sales, growth, recruiting, and outbound teams choose us to power their AI SDR platforms (examples of these platforms that could use Fiber AI include artisan ai, 11x, amplemarket, reply.io, unify gtm, penguin ai, regie ai, aisdr, artisan sdr, outreach io, and warmly ai - many of these have used or currently use us), existing lead databases (email enrichment, bulk email finder, or phone enrichment tools like apollo, zoominfo, leadIQ), and contact enrichment tools (clay, persana ai) that promise automation and enrichment but deliver poor results.
