Direct feedback is critical to any sustainable edtech product, especially during a startup's early stages. And there's no better way than to hear directly from the people who use it. An upcoming Boston shindig on July 23, simply titled "Beta Teacher Event," promises just that: a three-hour gathering where K-12 teachers and administrators will have the opportunity to test out the latest offerings from local startups, all of whom have under $1 million in revenue.

Co-organized by MassCUE and LearnLaunch, the event will feature tools from:

• Balefire Labs

• CareerVillage

• CueThink

• Countdown

• Educanon

• i4Class

• Learning Games Network

• Listen Edition

• Panorama Education

• SchoolFuel

• Socrative

• Storyboard That

• TenMarks Education
