Durham's DayOf Wants Businesses to Know What Their Events Are Worth

DURHAM, November 3 (Hypepotamus) - In-person events are all the rage in marketing in 2026. Part of that seems to be a natural response to our AI Age, as digital channels are getting diluted with more ad slop than we know what to do with. But getting people into a room and proving that the gathering helped grow a business are two different challenges.

For North Carolina-based entrepreneur Marc Eder, the question marketers need to be asking is: “How do events make money for a business?”

It is a question that Eder and Misha Shvets are looking to answer with DayOf, a MarTech startup that helps businesses connect in-person events to their sales efforts.

The company describes its platform as a revenue operations (RevOps) engine for in-person events. The goal is to help teams track whom they meet, what happens next, and whether an event was worth the investment.

Tech Square Ventures is an Atlanta-based firm investing in enterprise (B2B) and marketplace technology companies.

Building Your Rolodex

Eder and Shvets initially built DayOf as a distribution channel for event and conference travel (Hypepotamus highlighted the early-stage company in March of 2026). But as Eder told us this fall, pilots with companies showed that “the unit economics just weren’t there.”

The opportunity they saw instead was helping businesses understand how their in-person marketing efforts contribute to revenue. That meant shifting the focus from local discovery to what companies accomplish by being at or hosting specific events.

It all starts with a simple text message. With DayOf’s Rolodex feature (which is free to use), a person at an event or conference can text a photo of a badge or business card to the Rolodex number, add any notes, and build a list of the people they met. There is no app to download, and contacts stay connected to the notes that give each conversation context.

“Rolodex has been in open beta since early October. The people using it are founders, investors, and sales and marketing professionals at growth-stage B2B companies. Most discovered it at SF Tech Week or Venture Atlanta. We also have a few teams running the paid team version at events over the next few weeks,” Eder added.

The paid version of the DayOf workspace brings that activity together across a team. Businesses can create target lists from their customer relationship management system (CRM) or from attendee lists, set event objectives, and monitor progress during the gathering. DayOf also markets tools for events companies host themselves, including managing invitations, checking in guests, and compiling reports. Its reporting is designed to connect event spending with conversations, target accounts reached, and sales opportunities associated with those interactions.

Ultimately, Eder wants to help companies make “data-driven decisions” about where they send their teams and how they spend their event budgets.

DayOf is targeting marketing directors, field marketers, and event marketing teams, Eder added. He also sees an opportunity to partner with conference organizers to provide anonymized data about an event’s business impact.

Building In Public

DayOf is putting its product plans public. A link at the top of its website leads to a roadmap showing near-term priorities, longer-term ideas, and recently released features.

“Publicizing our roadmap is about building in public. We want our customers to have a clear idea of what's coming and to give them a channel to influence it,” Eder told Hypepotamus.

So what’s up next for DayOf? HubSpot and Salesforce integrations among its near-term priorities, with Slack integration planned further out. Users can also submit feature requests and follow updates on capabilities they want.
