The great nuisance of modern business is that it keeps asking people to behave like businesses. Wait on hold. Download the app. Remember the password. Listen to a voicemail that says somebody has also sent an email. Mike Mixon built his most consequential company around a less ceremonial idea: send a text to the number already in the customer's hand.
That idea became Textel, the St. Louis business-texting company Mixon co-founded with James Diel and John Meany in 2014. Diel led as chief executive, Meany owned the technical brief, and Mixon carried the commercial argument. His titles shifted with the young company - CMO in one early account, chief revenue officer in later records - but the assignment remained legible. Make a useful product understandable, sellable and repeatable.
By the time Capacity acquired Textel in January 2023, the texting platform worked with more than 1,700 customers. The deal folded SMS into a broader system for automating customer and employee support. It also offered a pleasing bit of corporate logic: Capacity had intelligence and workflow across several channels; Textel had spent years learning what happens when a customer would rather tap a reply than make a call.
01 / The habitThe shortest distance to the customer
Mixon arrived at Textel through the prosaic school of selling things. He worked as a sales representative at Gravity Payments beginning in 2005, then spent eight years as vice president of sales at Ram Board, a maker of temporary floor protection. Payments, construction supplies and cloud messaging make an eccentric product shelf. The connecting skill is persuasion disciplined by a pipeline: find the buyer, clarify the problem, and keep the next action visible.
Early Textel addressed small businesses that wanted to text from their existing landline number. No fresh number to advertise. No consumer app to coax onto a phone. Setup, Mixon said, could take less than 15 minutes. The company sold across verticals as varied as insurance, car dealerships and salons, using inside and outside sales. It was a focused promise for an unfocused truth: nearly every business needs to communicate, and nearly every customer has already decided which channel feels easiest.
“We're not flying blind anymore.”Mike Mixon on making Textel's sales pipeline visible
The sentence is not founder poetry. That is its charm. In an interview about Textel's own marketing stack, Mixon described a familiar small-company muddle. Prospects moved through the sales cycle with too little visibility. Email nurturing was sparse. Representatives lacked useful signals about which buyers had engaged with the company's material.
Automation gave the team a dashboard, drip campaigns and a way to score attention. Mixon reported that monthly sales rose by more than 25 percent after the change. His favorite features were not mystical: the email campaigns, the pipeline view, the score tracker. A revenue operator's romance is often a table that tells the truth.

02 / The testA 60-day clock and a 30-day launch
Simple propositions become serious companies when they survive difficult customers. A revealing Textel project involved Pearson's recruitment services operation. The existing voice-first process leaned on repeated call attempts to prospective learners. Contact rates were low, calls could be mislabeled as spam, and the method risked turning interest in education into a small siege by telephone.
Pearson wanted an SMS-first workflow integrated with Salesforce and NICE inContact. The deadline was 60 days. Mixon later called the period intense. Textel scoped the implementation and roadmap within the first two or three weeks, then deployed after 30 days. The redesigned flow asked qualifying questions by text and passed suitable prospects to enrollment advisers.
The important detail is not merely speed. It is that Mixon's revenue role sat close to delivery. Enterprise software is full of elegant demonstrations followed by months of administrative fog. Here, the commercial promise had to survive contact with systems, workflows, advisers and people deciding whether to continue their education. The workflow had to be useful on an ordinary working day, not merely persuasive in a conference room. Pearson reported reducing contact attempts by two-thirds while contact rates rose by more than 200 percent.
On that recorded conversation, Mixon and Diel ranged beyond plain SMS into text-bot personality and RCS, the richer messaging standard. The discussion captures a company beginning with an ordinary channel while looking toward a more expressive one. Yet the practical principle stayed intact: technological sophistication mattered only if it improved the exchange between a person and an organization.
03 / The fitThe missing channel finds its platform
Textel expanded from the small-business pitch into contact centers, where partnerships became leverage. Its product connected with major CCaaS, UCaaS and point-of-sale platforms. By 2020, public company records put the customer count around 800 in North America. At acquisition, the figure had moved beyond 1,700, with customers around the world.
Capacity, founded in St. Louis in 2017, approached the same burden from another direction. Its software automated repetitive support across chat, web, mobile, email and internal messaging. SMS was the conspicuous gap. Capacity chief executive David Karandish described Textel's expertise as the piece that could extend automation to business texting. Diel described Textel's partner network as an easy button for the combined organization. The phrase is almost suspiciously tidy, but the product fit was real.
For Mixon, the transaction converted a founder's concentrated bet into part of a larger suite. He stayed with Capacity, working in revenue and partnerships as the company accumulated capabilities through further acquisitions. In 2024, the Textel by Capacity team sent him to Genesys Xperience alongside Dave Cebrowski and Anthony Heumann to discuss SMS support and customer experience with AI. The channel that once needed explanation had become part of the AI conversation.

04 / The scaleAfter the exit, the work gets larger
An acquisition supplies a neat ending for a startup profile and a messy beginning for everyone employed by the merged company. Products overlap. Teams inherit new acronyms. Customers still expect the software to work on Monday. Mixon's continued presence matters because the acquired knowledge was not confined to code. It lived in partnerships, sales conversations and years of watching contact-center buyers decide what they could safely change.
In June 2026, Capacity said it had passed $100 million in annual recurring revenue, up from $5 million in three and a half years. The company reported more than 20,000 organizations and 1.5 million users. In September it announced more than $54 million in Series E funding, bringing the total raised to more than $159 million. Planned investments included product development, go-to-market and customer-success teams, strategic partnerships and international expansion.
Mixon marked the milestone without claiming the spotlight. Writing about the period since Capacity acquired Textel, he said it had been incredible to watch the growth from inside and that he was grateful to be part of the team. That tone fits the visible career. His public footprint is made less of manifesto than of operating notes: the pipeline became clearer; the rollout took 30 days; the integration let a customer do something useful.
A focused company can become valuable by owning one channel deeply enough that a larger platform cannot sensibly ignore it.The Textel lesson
There is a wider irony here. Artificial intelligence has made customer service sound newly futuristic, while much of the job remains an argument about manners. Do not make people repeat themselves. Do not trap them on hold. Do not require another download for a question that fits in one line. Respond in the place where they asked.
Mixon's contribution to that argument was commercial discipline. He did not invent the text message, and Textel did not need him to pretend otherwise. The company made texting usable inside businesses with old numbers, existing contact-center systems and revenue targets. It supplied the integrations, timing and measurement that turn an obvious consumer habit into enterprise infrastructure.
The result is a career with a satisfying loop. A sales representative learned to see the next step. A sales leader built systems that made the step visible to others. A founder attached those systems to a communication channel customers already preferred. Then a larger company bought the missing channel and kept the operator. In technology, the future often arrives with trumpets. Mixon's version arrived as a notification.
