If you follow the wizard at https://travel.state.gov/content/travel/en/us-visas/visa-information-resources/wizard.html, you should get your answer. I followed it through based on what I understand is your information, and it appeared that the Visa Waiver program applied to your visit. Visa Waiver doesn't apply to all nationalities, but it's your UK nationality that qualifies you.
Here's what the wizard results said:
Most citizens of United Kingdom can travel to the U.S.for Business for 90 days or less without a visa under the Visa Waiver Program.
Examples of visa waiver travel: Consulting with business associates, Travel for a convention or conference, Negotiating a contract
Note that these are examples; the general statement also applies to you.
Of course, you should do the wizard yourself.
