Company profile

researched Aug 2026

SendHub operates a business text messaging platform that combines mass SMS and MMS campaigns, two-way conversations, scheduled reminders and voice calling. Core product features include a shared inbox for managing text conversations, unlimited groups with text-to-join keywords, merge fields and reusable SMS templates, hosted SMS for text-enabling existing landline or VoIP numbers, inbound and outbound MMS with attachments, an analytics and reporting dashboard covering deliverability and messaging/voice exports, and a contact database with tagging, filtering, segmentation and list import. Each account is provisioned with a dedicated text-enabled local number in a chosen area code, and existing numbers can be ported in; additional lines can be added at any time.

The platform exposes a public API with documentation and connects to more than 100 apps. Direct integrations include Microsoft Teams, Webex, Follow Up Boss and JazzHR, with further connections to Gmail, Google Ads, Google Calendar, Google Forms, Slack, Mailchimp, Facebook, Typeform, Salesforce, Shopify, WooCommerce, TikTok and AWeber available via Zapier. SendHub markets itself as HIPAA-ready and GDPR compliant, and organizes its offering around industry verticals such as healthcare, heavy equipment, nonprofits, real estate, recruiting and restaurants, plus solution categories including bulk SMS, mass texting, SMS notifications, two-way texting, scheduled texts and group messaging.

Earlier in its history the company positioned itself as an enterprise phone service that let businesses create virtual phone numbers and add them to employees' existing mobile devices, with a stated long-term goal of replacing PBX systems with mobile apps and online dashboards. Features at that stage included toll-free lines, call routing to personal cell phones, voicemail transcription, call forwarding and transfer, contact sharing, group texting, SMS short codes and file attachments sent over SMS. A 2013 product, SendHub Manager, gave administrators an online dashboard to provision, add and remove large numbers of employee phone lines without IT involvement.

Business model

SendHub sells its messaging and voice platform as a subscription SaaS product, offered on monthly or annual plans that can be cancelled at any time, with a 14-day free trial and custom enterprise plans sold through a sales team.

Revenue comes from tiered monthly or annual subscriptions: Lite at $19/month ($219/year) with 500 SMS per month, Lite+ at $37/month ($400/year) with 1,000 SMS, Starter at $52/month ($570/year) with 2,000 SMS, and Basic at $100/month ($1,000/year) with 4,000 SMS plus setup, training and an account manager; a custom tier is quoted individually and adds outbound MMS and dedicated short codes. Overage and surcharge fees apply, including $0.025 per voice minute beyond plan allowances, per-segment charges for Canada, Puerto Rico and Guam, and one-time 10DLC brand ($5) and campaign ($15) registration fees.

Traction

SendHub reports 10,000+ monthly users, 100+ reviews and a 4.5 average rating. Earlier reported milestones included 5 million cumulative messages and 2 million messages per month by October 2012, growth from 5,000 to 25,000 users over that period, monthly active users at about 75% of total, an 11% conversion rate for users of six months or more, revenue in the mid-five figures per month with 25% monthly growth as of 2013, and one beta customer, iCracked, provisioning over 300 lines through SendHub Manager.

Latest developments

The company's website footer identifies SendHub as a New Era Technology company, and its plans note that U.S. customers must complete 10DLC brand and campaign registration before using the free trial.

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

Market position

SendHub states it has more than 10,000 users monthly, over 100 reviews, an average 4.5-star rating across business review sites and more than 10 years of service delivery. In 2012 press it was described as a contender against Google Voice in the business communications market, where carrier control of the market was cited as a barrier to entry.

Public coverage from 2012-2013 positioned SendHub as a Google Voice alternative that kept all communications with a contact - calls, missed calls, voicemails and text messages - in a single stream and made features fully available through the web rather than only on a handset, while separating business and personal numbers on one device. Current positioning emphasizes HIPAA readiness, GDPR compliance, 100+ integrations, an open API, hosted SMS for landline and VoIP numbers, and simplicity of setup.

Technology

The platform is a cloud-based SMS/MMS and VoIP service delivering group messaging, keywords, short codes, toll-free and local 10-digit numbers, number porting, hosted SMS on landline or VoIP lines, scheduled sending, merge-field personalization, a deliverability analytics dashboard, and a documented REST-style API with 100+ app integrations.

Go-to-market

SendHub sells self-service subscriptions through online sign-up and a 14-day free trial, alongside a sales-assisted motion for custom plans that includes demo booking, a sales phone line, setup and training, and a dedicated account manager on higher tiers. Distribution is supported by an integrations ecosystem spanning direct connectors and Zapier, vertical landing pages by industry, and a content blog covering SMS marketing topics.

Businesses and organizations that need one-to-many and two-way customer, employee or member messaging, with named verticals including healthcare, heavy equipment, nonprofits, real estate, recruiting and restaurants; cited users include a university research lab using the service for participant reminders and, in earlier coverage, schools, clients and a field-technician workforce.

Geography

Service is currently available in the United States and Canada, with international service described as planned; surcharges apply for messages to Canadian, Puerto Rican and Guam numbers. FundersClub lists the company in Menlo Park, California.

History

SendHub went through Y Combinator in the winter 2012 batch and was described in 2012 press as an SMS-for-organizations product that grew from roughly 5,000 to 25,000 users and from 1 million to 5 million messages sent between mid and late 2012, adding calling and voicemail in June 2012 and shared groups in October 2012. It raised $2 million in seed funding in April 2012, took an undisclosed investment from former Florida Governor Jeb Bush announced in October 2012, launched SendHub Manager in January 2013, raised a $3 million Series A led by Bullpen Capital in September 2013 after an equity crowdfunding round of nearly $2 million described by its founders in October 2013, and announced $5 million in further funding in November 2014. The company is now presented on its website as part of New Era Technology.

Risks & controversies

Founders publicly described being turned down by more than 50 venture capital firms when attempting to raise a Series A in 2013 before using crowdfunding. Service is limited to the U.S. and Canada, and U.S. messaging requires carrier-mandated 10DLC registration approval before traffic can be sent.
