Company profile

researched Aug 2026

Novel Effect is a Seattle-based educational technology company that makes a mobile and web application which listens as an adult reads a children's book aloud and plays synchronized "soundscapes" — interactive music, sound effects and character voices — timed to the reader's position in the text. The app works with print copies of books that families, classrooms and libraries already own, and also offers in-app ebooks. Readers select a title, start the soundscape, and read aloud; the system follows the voice and tolerates pauses, discussion, page skipping and re-reading.

The library of titles is selected by staff and the audio is produced by soundscape designers, musicians and voiceover actors, spanning board books, picture books, early readers, graphic novels and non-fiction. Alongside the audio, the company publishes educator-developed book activities, printables, discussion questions, writing prompts, read-aloud calendars and blog resources, and sells accessories such as Bluetooth speakers and book spine stickers. Co-founders Matt and Melissa Hammersley have also authored read-aloud guidance for educators, including "Rock Your Read Aloud: Sparking Curiosity and Confidence in Little Readers" and a Jossey-Bass (Wiley) title announced as "The Joy of the Read-Aloud."

The company positions the product around literacy outcomes — fluency, vocabulary, background knowledge, comprehension and analytical reading — as well as student focus and social-emotional connection during read-aloud time.

Founding story

Melissa Hammersley, a visual/graphic designer who had specialized in patent drawings, and Matt Hammersley, a patent attorney working with voice recognition, conceived the idea at their baby shower while expecting their first child, Eleanor, after watching a friend read a book aloud with silly voices and sound effects that captivated the room. Two months later they quit their jobs and sold their home to bootstrap the company, finalizing plans for a proof of concept the day before their daughter was born, and built a working prototype.

Business model

Subscription software sold both to individual consumers and to institutions. Individual plans are advertised from $49.99 per year (an annual plan listed at $95.88/year) or from $7.99 per month, with a free tier usable indefinitely and a 7-day free trial for new subscribers. School, district and library plans provide shared unlimited Premium access across a community, are quoted custom, and accept purchase orders and p-card payment. The company also sells ancillary items including book activity downloads, Bluetooth speakers, book spine stickers, gift bundles and a print book.

Recurring consumer and institutional subscriptions to the soundscape library, supplemented by sales of book activities, accessories and gift bundles.

Traction

The website cites a 4.9 rating across 8,000-plus reviews and a library of more than 1,000 soundscapes plus hundreds of in-app ebooks. Company survey data of general subscribers is reported as 9 in 10 saying books are more engaging and 8 in 10 saying they are more confident reading and want to read more often. The team numbered 11 people in 2017; a third-party profile lists an 11-50 employee range.

Latest developments

Co-founders Matt and Melissa Hammersley signed with Jossey-Bass, a Wiley brand, for "The Joy of the Read-Aloud," announced for release in Spring 2024, and the company publishes "Rock Your Read Aloud: Sparking Curiosity and Confidence in Little Readers." Current offerings include Novel Effect Web alongside the mobile apps, a library of over 1,000 soundscapes, and school, district and library plans with custom quotes.

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Describes itself as the only app combining children's storybooks with speech recognition to trigger interactive audio during read-alouds. Third-party profiles categorize it within AI/NLP-and-voice and edtech startups in Seattle. Recognition includes participation in the 2017 Alexa Accelerator powered by Techstars, a Shark Tank feature of its patented technology, and Webby, Cynopsis, Parents' Choice, Mom's Choice and American Association of School Librarians Best Digital App awards.

Enhances physical books already on classroom, library and home shelves rather than requiring proprietary hardware or replacing print; the speech-following system lets readers pause, skip or re-read without losing sync. Content is curated and professionally produced, paired with educator-developed lesson resources and curriculum-aligned titles, and the company reports a kid-safe app plus institutional purchasing options such as purchase orders and p-cards.

Technology

Voice recognition applied to read-aloud audio: the app uses the company's own algorithms and a customized speech recognition system to determine the reader's precise location in a book and synchronize theme music, sound effects and character voices. The company describes the approach as "voice-first storytelling" and holds patented technology (patent-pending as of 2017; one patent assigned according to a market-data profile). Delivery is via iOS and Android apps and a web app.

Go-to-market

Self-serve app download and free trial via the App Store, Google Play and Novel Effect Web, converting into individual subscriptions; institutional sales through demos, custom quotes and school/district/library plans with onboarding pages and FAQs. Content marketing (blog, activity printables, read-aloud calendars, an educator-facing book) and educator testimonials support acquisition. The founders have described a reciprocal model with book publishers, in which Novel Effect markets publishers' titles to its users while publishers promote the platform, intended to keep customer acquisition cost low.

Schools and districts, public libraries and other organizations, school librarians and classroom teachers (with materials aimed at pre-K through elementary and some secondary library use), plus families and homeschoolers.

Geography

Headquartered in Seattle, Washington, United States, selling to U.S. schools, libraries and families through app stores and the web.

History

Novel Effect launched in 2015 with an app for iOS and Android that added sound effects to popular titles such as "Where The Wild Things Are" and "The Cat in the Hat." In 2017 the 11-person team joined the inaugural Alexa Accelerator run by Amazon with Techstars Seattle, with Matt Hammersley as CEO, Melissa Hammersley as Chief Design Officer and Kevin Coulton as CTO. The company bootstrapped, then raised angel funding after establishing product-market fit and venture capital to scale, with a round reported in May 2018. Its patented technology was featured on Shark Tank. The product expanded from consumer story time into school, district and library plans with educator resources, and the founders signed a book deal with Jossey-Bass (a Wiley brand) for "The Joy of the Read-Aloud," announced for Spring 2024 release.

Risks & controversies

Engagement and confidence statistics promoted by the company are drawn from its own subscriber surveys rather than independent evaluation. The product depends on licensed third-party children's titles and on publisher relationships, and on speech recognition performance in classroom settings. Third-party profile data on funding, revenue and headcount is estimated and differs from other records.
