She sent 150 emails to contractors for her own renovation. Most went unanswered. So she built the software they never had.
// Founder & CEO, Eano · San Mateo, California
The Story
She is the rare founder who can read a quarterly ad-spend dashboard and a contractor's invoice with equal fluency. Today Stella Wu runs Eano, a San Mateo company that began as a way to survive a single ADU project and turned into all-in-one software for the people who build things - the drywall hangers, the bathroom crews, the one-truck general contractors who never had a CRM, let alone an AI estimator.
Start with the spreadsheet that never balanced. In 2017 Wu bought a house and decided to add an accessory dwelling unit. What followed reads less like a home-improvement story and more like a case study in market failure: 150-plus emails to contractors that mostly went into the void, bids that swung from $40,000 to $100,000 for the same scope, a permit that took 350 days, and more than $1,000 spent on the wrong materials because nobody told her otherwise.
Most people would have framed the finished room and moved on. Wu, who had just spent four years at Wish learning how to move millions of dollars through paid-acquisition funnels, looked at the mess and saw a structure underneath it. The contractors were not the villains. They were affordable, skilled, and almost completely cut off from the homeowners who needed them - no marketing, no admin, no software, no leverage. The market was not broken because the people were bad. It was broken because the rails did not exist.
She started laying them herself. First informally - helping friends manage their bathroom and ADU projects, acting as the translation layer between a homeowner's anxiety and a crew's calendar. By 2019 the side-favor had a name: Eano, short for Easy Affordable Renovation. The early product walked homeowners through a renovation and connected them to vetted, licensed, insured contractors. The later product turned around to face the contractors directly, handing them the sales, scheduling, and payment tools that every other industry had taken for granted for a decade.
That pivot - from a consumer renovation service to the operating system for the trades - is the throughline of Wu's work. She is not trying to make renovation cute. She is trying to give a 150-year-old industry the same software dignity that her old employer gave to discount shopping.
The early Eano focused on the homeowner: pair them with vetted, fully licensed and insured professionals, keep every conversation and milestone in one place, and offer pricing transparent enough that the project would not surprise anyone halfway through. During the pandemic, when everyone was suddenly staring at the walls they wanted to change, the model caught fire - contract revenue grew roughly fivefold, and the business was up about 70% year over year in the first quarter of 2021. It was enough to convince Builders VC to lead a $6 million Series A, joined by Newfund, Celtic House, and - tellingly - Wish co-founder Danny Zhang, who had watched Wu work up close.
But the more interesting move came later, when Eano turned to face the other side of the market. The contractors Wu had once chased for quotes became the customers. Eano Pro positions itself as a single system where an independent builder can run marketing, sales and estimates, project management, daily logs, and financial reporting - with AI doing the grunt work of generating estimates and surfacing what needs attention. It is, in effect, the back office that the one-truck contractor never had time or money to assemble.
Exhibit A
It helps to be specific, because the specifics are what radicalized her. When Wu set out to add an accessory dwelling unit to her own home in 2017, she was not a naive customer. She had spent years buying attention at internet scale. And still the process humiliated her.
She could not find a reliable, affordable general contractor. The ones she reached barely answered - she fired off more than 150 emails and got near silence in return. The quotes she did receive were not slightly different; they ranged from $40,000 to $100,000 for what was, on paper, the same job. There was no shared language for what a fair price even looked like. Timelines were a rumor. The permit alone took 350 days. At one point she spent over $1,000 on the wrong materials simply because no one in the chain flagged the mistake before the money was gone.
Worst of all was the trust problem. There was no way to tell, in advance, whether a contractor was any good. The information that every other consumer market takes for granted - reviews, transparent pricing, a paper trail of communication - did not exist here. The buyer was flying blind and the seller had no incentive to turn on the lights.
Wu's diagnosis was unsentimental. The renovation industry, she argued, had simply skipped the modernization that reshaped retail, travel, and finance. The trades were not behind because the people were behind. They were behind because nobody had bothered to build the rails - the pricing transparency, the communication layer, the project tracking - that the rest of the economy runs on. So she wrote them.

Before The Startup
Wu did not parachute into construction from a coding bootcamp. Her parents worked in the trades, and she spent her childhood around builders, materials, and the specific rhythm of a project that runs long. What stuck with her was not the dust. It was the work ethic - the way her parents treated a client's home as something worth getting right.
That detail matters, because it complicates the easy narrative. The people who fund construction tech love to describe Eano as an outsider's assault on a sleepy industry. Builders VC partner Jim Kim put it bluntly: you don't have to be "a 55-year-old man wearing steel-toed boots" to change construction. True. But Wu is also an insider's kid, which is why Eano reads less like disruption and more like a daughter building the tools her parents never had.
Her formal training points the other way entirely. She studied psychology at UC Berkeley, graduating in 2012 - a degree about how people make decisions, which turns out to be excellent preparation for both growth marketing and for convincing a skeptical contractor to try new software. Before Eano she had already founded one company, haidaiji.com, and done business development at Tune and MdotM. The renovation founder was a repeat founder before most people had heard her name.
The Wish Years
In 2015 Wu joined Wish as the first hire in marketing, back when the e-commerce app was scaling toward becoming one of the most-downloaded shopping platforms on earth. By the time she left in 2019, she was running growth on a budget north of $400 million a year, squeezing paid-acquisition channels for returns that hit 10x on ad spend.
It was a crash course in unit economics, attribution, and the unglamorous discipline of making a dollar of marketing return more than a dollar of revenue. She would carry all of it into a far messier industry - one where the "customer" might not check email for three days because he is on a roof.
The lesson she talks about most is not a tactic. It is leverage: the realization that the contractors she later built for were great at the work and starved for distribution. Wish taught her how distribution actually works. Eano is what happens when you point that knowledge at the trades.

The Long Way Around
Why She's Different
Investors sell her as the outsider shaking up construction. The truth is sneakier - she's a construction kid who learned software, building the tools her own parents never got.
Most founders learn marketing on the job. Wu arrived with $400M of Wish ad spend behind her, then pointed that machinery at an industry that had never been marketed to properly.
Eano isn't a thesis. It's a receipt. Every feature traces back to a specific failure in her own renovation - the silent contractor, the wild quote, the 350-day permit.
The Margins
What's Next
Give a 150-year-old industry the software it was never offered.
Wu's aim is end-to-end: transparency for homeowners, and for the independent contractor, the reach and tooling to run a real business. The same leverage Wish handed to merchants, handed instead to the person framing your garage.
