The phone rings at a small service business. The owner is under a sink, on a ladder, inside a crawlspace, or standing in front of the customer who arrived five minutes early. The call goes unanswered. No trumpet marks the lost sale. There is only a tiny silence, followed by the caller trying somebody else.
Anand Valavalkar learned to notice that silence while he was still in high school. He had started a smart-home, networking, and audiovisual installation company in South Texas, the sort of education in business where the syllabus is written by clients and the exams arrive as invoices. It grew beyond $100,000 in yearly revenue. He installed systems, sold phone setups to other small businesses, recruited friends when jobs became too large to handle alone, and watched money leak from perfectly competent operations for a painfully ordinary reason: nobody could answer every call.
Years later, he would turn that observation into Twine, the San Francisco company he co-founded and now leads. Twine gathers inquiries from calls, texts, web forms, chats, Google, Yelp, and ads. Its AI responds, qualifies the person, follows up, books the work, and shows the business which channels are producing revenue. The product sounds like a compact sales department. Its founding insight sounds like common sense. That combination is precisely the point.
Before the AI, a better sign-in sheet
Valavalkar had already discovered the pleasure of making dull work disappear. As a student club leader, he was annoyed by five-minute paper sign-in lines and the hours officers spent tallying attendance afterward. The irritation became Clubhouse, an app that let students check in quickly and gave organizers useful records for service hours, elections, and awards.
Clubhouse won the 2019 Congressional App Challenge in Texas’s 23rd District, was invited to CES 2020’s startup showcase, and eventually reached more than 40,000 users. The number was important because it changed the status of technology in Valavalkar’s mind. Code was no longer an abstract ability or a private fascination. It could solve a recognizable problem for strangers at scale.
“CAC was the first time tech felt real to me: something I could use to solve problems in the world around me.”Anand Valavalkar, 2025
That conviction had been rehearsing for years. Valavalkar moved through five states and seven cities as a child. In a personal essay, he described technology as the constant among changing schools, homes, and friends. He watched Apple keynotes, read TechCrunch, joined a Lego robotics club, and built his first computer before middle school. At one point he tried not to let technology become his whole identity. The attempt added interests rather than removing the original one: cycling, coffee, Formula 1, music, design, and a persistent curiosity about whatever might come next.
The moves also gave him a useful social flexibility. His public record is crowded with group projects: leading a large high-school mathematics society chapter, organizing TEDxYouth@Austin for more than 500 students from 44 schools, creating a computer-literacy program for preschoolers, and volunteering at a summer camp. Software was one instrument in a larger habit of convening people and reorganizing friction.
The apprenticeship of useful shortcuts
At the University of Texas at Austin, Valavalkar studied computer science. His course list ran from data structures and computer systems to machine learning, natural language processing, and modern web applications. Outside the classroom, his work kept pulling toward the distance between information and action. At Superhuman, he developed and launched Smart Links, a feature that surfaces an important link from an email and lets a user open it with a keyboard shortcut. At Vestaboard, he helped build web applications for the company’s installable platform.
Look backward and the projects begin to rhyme. Clubhouse shortened the trip from arriving at a meeting to recording attendance. Smart Links shortened the trip from reading an email to opening its useful destination. Twine shortens the trip from “I need this service” to “you are booked.” None requires a manifesto. Each removes a small patch of waiting.
The installation company provided something a computer-science curriculum could not: an embodied understanding of interruption. A service owner is not ignoring leads out of laziness. The work itself occupies the hands, eyes, and attention. Software earns its place when it respects that reality. It should receive the interruption, keep the potential customer warm, and return a useful result without creating another administrative ceremony.
Valavalkar has written about the elementary mistakes he encountered as a contractor: neglecting an online presence, showing up in the wrong places, underestimating reviews, letting customer service slide, and waiting too long to ask for help. The tone is practical because the tuition was practical. When larger jobs arrived, friends became extra hands. When a prospect searched, a professional website became a piece of trust. These are modest observations with balance-sheet consequences.
His advice from that period contains a useful contradiction. A young builder naturally wants to prove he can do everything. A growing operator eventually learns that doing everything is one more way to become the bottleneck. Valavalkar has said that bringing in friends for larger installation jobs preserved the quality of the work as demand increased. Twine applies a software version of the same lesson. The owner does not surrender the customer relationship; the repetitive first response is handed to a system so the humans can arrive where judgment matters. Automation, in this view, is less a replacement than a carefully placed extra pair of hands. It works only if it knows when to speak, what to ask, and when to step aside. That last part rarely makes the product demo, but it decides whether the tool feels like help.
A summer project refuses to stay small
Twine began in 2023 with co-founders Omar Imtiaz and Divyesh Khatri. The early pitch was deliberately narrow: when a small business missed a call, Twine would text the caller, learn what they needed, and help put an appointment on the calendar. The team entered Y Combinator’s Summer 2023 batch, and Valavalkar left UT Austin to build full time.
The narrow wedge broadened. A missed call is only one doorway into a business. Leads also arrive through forms, chat, text, ads, and marketplace listings. A quick reply matters, but so do qualification, repeated follow-up, scheduling, payment, review requests, and knowing which marketing channel actually deserves another dollar. Twine’s description evolved accordingly, from an AI text receptionist into an AI revenue engine for local service companies.

By 2025, Valavalkar said Twine powered hundreds of businesses, including plumbers, pest-control operators, spas, lawyers, and accountants, and had helped them capture millions of dollars in revenue that might otherwise have disappeared. Those figures are company-reported, but the range of customers reveals the shape of the bet. Twine is not organized around a single trade. It is organized around a recurring condition: valuable work happens away from the inbox.
There is also a lesson in how Valavalkar describes the company. The artificial intelligence is not presented as a parlor trick. It is attached to verbs a business owner can price: respond, qualify, follow up, book, collect, retain. For all the talk about agents and models, the customer’s question remains wonderfully provincial: did the phone call become a job?

Necessary things, and perhaps a coffee shop
Valavalkar’s ambitions are broader than lead management. On his personal site, he writes about connecting code to consequential problems. He follows artificial intelligence, the future of work, design, kinetic art, music, food, and the strange pleasure of arranging a playlist so one song appears to melt into the next. The list feels less like branding than an open browser with too many good tabs.
Asked where he hoped to be in 2035, he offered a compact standard: still building things that feel necessary, with people he admires, and still having interesting conversations. He imagines tools changing and fields colliding, but the working method staying recognizable: find something underrated and useful, then push it as far as it can go. After laying out the decade, he added a smaller ambition. Maybe he would finally have a coffee shop.
It is a fitting coda for a founder whose story resists separating the grand system from the ordinary encounter. A coffee shop is a thousand tiny operations disguised as a pleasant room. Someone must notice the empty cup, the slow line, the regular at the door. Technology can help, but attention comes first.
That is the thread from Clubhouse to the contracting business to Twine. Valavalkar does not begin with the size of the technology. He begins with the size of the annoyance. Paper attendance takes too long. A useful email link is buried. A business paid for the phone to ring and then missed its chance to answer. Each problem is almost too familiar to see. He sees it, follows it, and gives the silence somewhere productive to go.
