SendHub

Overview

SendHub gave organizations a shared business phone system built around text messaging. Teams could claim a number, organize contacts, send group or individual SMS, receive replies, and add voice, files, and conference calls without installing telecom hardware. The company joined Y Combinator's Winter 2012 batch.^[1]

Cameo Global acquired SendHub in June 2016 for an undisclosed price. SendHub had proven that business communication could move from desk phones to messaging; Cameo supplied global telecom infrastructure, voice expertise, contact-center customers, and distribution. The exit reflected channel fit more than product failure.^[2]

Founding Story

The product began with two communication gaps. Garrett Johnson worked for the U.S. Senate Committee on Foreign Relations and saw text messaging used in programs in developing countries. His nephew's school, meanwhile, struggled to reach families in under-resourced communities. Email missed households without computers; those families still had cellphones.^[3]

Johnson and Ash Rust connected the problems and built an education-focused SMS tool. Rust had served as a British Army officer, studied computer science at Oxford, run a web consultancy, and later directed ranking at Klout. The acquisition note names Garrett, John, Ryan, and Rust as the group working on SendHub full time nearly five years earlier.^[4]

The team faced an early objection that texting was already solved. It disagreed because consumer SMS did not give organizations shared identity, permissioned team access, contact groups, message history, or operational controls. “We wanted something simple: to make it easier to communicate,” Rust wrote when announcing the sale.^[4]

Education supplied the wedge; customers widened the market. Schools used texts for homework and parent communication, while companies used the same system for mobile workers, deliveries, and customer updates. Rust later explained why the channel endured: “We all have cellphones, and we can all get texts; there's no need for an app to deliver the info your customers need.”^[3]

What They Built

SendHub turned a phone number into shared software. An administrator added contacts and groups, invited teammates, and sent individual or bulk texts from web or mobile. Incoming replies returned to the same business identity rather than a worker's personal number. The product also supported calls, files, and conference calling.

The system served people outside an office: teachers, field workers, delivery teams, political organizations, and customer-service groups. SMS required no recipient app or smartphone data plan. That universality was the core distribution advantage.

SendHub's value was not carrier transport alone. It managed identity, contact segmentation, shared history, access, scheduling, and collaboration. A school could send an assignment to one class; a business could notify workers or customers; an enterprise could integrate messaging into a workflow.

The customer list crossed segments. The acquisition announcement named Lyft, Teach For America, Booz Allen Hamilton, Berkshire Hathaway, and The Knot.^[2] The founders said messages ranged from delivery notifications and homework assignments to life-saving alerts in medical devices.^[4]

Market Position

Target Customers

SendHub started with educators reaching families, then sold to small businesses, mobile workforces, nonprofits, and large enterprises. Buyers needed fast deployment and broad recipient reach without issuing a new app.

Market Size

No reliable contemporaneous market-size figure was found. YC says thousands of companies used SendHub, while the founders said messages touched millions of people worldwide.^[1][4] Those are company descriptions, not audited usage data.
