Our mission
Pebble takes the manual scoring tables, the z-score arithmetic and the long evenings spent drafting a 13-section report off the diagnostician's desk, so the practitioner can spend that time on the part of the case that needs their clinical judgment. The platform is AI-assisted; it never replaces the diagnostician's expertise.
Built on real Israeli source materials
Pebble's scoring engine and report scaffolding stand on real, named Israeli batteries and grade-specific norm tables — not retrofitted US tests. We onboard further Israeli batteries as our partner diagnosticians supply normed reference data.
Aleph-Tav (ערכת א-ת)
Reading and writing battery used across Israeli schools, with grade-specific norms for grades 2 through 6 in production today and grades 2 and 3 documented against Ministry of Education-aligned reference tables.
Rey Complex Figure
Visual-spatial perception and visual memory test, normed by age across the 10 to 17 range used in school-age assessments.
Rey Auditory-Verbal Learning Test
Auditory-verbal learning and memory test with age- and sex-specific norms across the 8 to 17 range.
Leadership
Osnat Bar
Founder & CEO
Osnat Bar has spent more than a decade inside the diagnostic room. For eleven years as an authorized learning disability diagnostician in Israel, she sat across from children whose cognition was misread by systems built to measure something else — and from parents waiting months for answers that arrived as static, impenetrable reports.
Before pebblearning, she founded Galai, a digital diagnostics platform that processed over 3,000 assessments — an early proof that clinical-grade evaluation could be delivered at scale without sacrificing rigor. That experience shaped pebblearning's central conviction: a learning disability identification should be the beginning of a child's story, not the end of a file.
Osnat holds an M.A. in History and Education from Bar-Ilan University and Ben-Gurion University, and brings deep operational fluency across the institutions where learning actually happens — public school systems, private clinics, and independent schools. At pebblearning, she leads the translation of clinical practice into product: every assessment, report, and learning pathway carries the judgment of someone who has done the work by hand thousands of times.
