How Fieldwire Broke ConTech’s $100 Million Curse And Ignored Every B2B SaaS Rule To Do It
Silicon Valley spent a decade telling ConTech founders that no construction software company could break the $100 million acquisition ceiling. In November 2021, Hilti bought Fieldwire for around $300 million. The founder, Yves Frinault, was a French paratrooper turned Ubisoft game developer who had never worked in construction. He spent $3-5K a month on Google ads, ran a freemium model nobody else was using, took half-pay to dodge a bad bridge round, and closed the acquisition in four meetings. Here’s how he ignored every B2B SaaS rule and broke the curse.
For most of the 2010s, ConTech had a quiet rule that nobody really wanted to say out loud. Construction software companies could grow, raise, even build a real product, but they would always hit a wall around $100 million. That was the ceiling. VCs accepted it. Founders priced their ambitions around it. The industry was just too slow, too fragmented, too allergic to change for anything bigger.
Then Hilti, the Liechtenstein-based tool company, paid roughly $300 million for a San Francisco startup called Fieldwire. The deal closed in Q4 2021. The team didn’t get absorbed and watered down. The founder didn’t ride off into the sunset. The product kept running, kept growing, and the team more than doubled inside Hilti.
What makes the story strange is who pulled it off. Yves Frinault never spent a day working in construction. He jumped out of planes for the French army, then went to Stanford, then made video games at Ubisoft. He didn’t follow a single rule of the standard B2B SaaS playbook. And that, it turns out, was exactly the point.
Fieldwire was built by an outsider who paid attention to what construction was missing rather than what other construction startups were doing. Cheap inbound, freemium onboarding, and a refusal to take bad capital let the company outlast every competitor that tried to brute-force the same market.
The outsider who saw what insiders couldn’t
Why a paratrooper-turned-game-dev was the right person for the job
Yves grew up in France watching his parents bring derelict farmhouses back to life out of physical binders. Photos of plumbing, photos of wiring, stacks of paper tracking every job on site. He knew, viscerally, how heavy that workflow was. Then he joined the army, did roughly 150 freefall jumps, finished his degree, and went to Stanford for a master’s in civil engineering. The plan was bridges.
The plan didn’t survive contact with Ubisoft. In 2008 he joined the gaming giant and was handed a team on day one. While everyone around him obsessed over making great games, Yves was watching a tidal wave nobody in construction had clocked yet. The first iPhone had just shipped. Gaming studios were managing complex, cross-functional teams with Jira, Trello, Basecamp – tools that updated in real time and kept everyone aligned. Construction was still walking back to the site office to log an issue on a clipboard.
That gap is the whole thesis. The people building skyscrapers were being coordinated with less sophistication than the people making PlayStation games. Yves saw the inflection point because he’d just lived through one. Gaming had gone from boxed retail to fully digital and connected. Construction was sitting at the same edge, and almost nobody inside the industry could see it because they had nothing to compare it to.
The anti-playbook: every B2B SaaS rule, ignored
Why Fieldwire’s go-to-market looked nothing like its competitors’
Every B2B software company building in 2013 ran the same play. Hire SDRs. Cold call. Build an outbound sales team. Hit your numbers. That was how it was done. Fieldwire didn’t do any of that, mostly because Yves didn’t have the team, the budget, or the culture to run it.
What he did have was a stint running performance marketing at Ubisoft. So Fieldwire spent $3-5K a month on Google Ads and ran the kind of funnel a consumer gaming company would run. In 2013, no other ConTech startup was bidding on the same keywords. The auctions were cheap. The intent was high. The competition simply wasn’t there. Combined with a freemium model lifted straight out of gaming – sign up free, run three projects, prove it works to yourself, then pay – Fieldwire built an inbound machine while everyone else was still loading up sales decks.
The first paying customer was a researcher mapping his lab equipment. Yves stapled the dollar to the wall and went hunting for the second. From there, growth came from the markets the Bay Area startups ignored. Atlanta. Canada. Cities that were underserved and hungry. Subcontractor adoption was the most violent of all. Crews don’t sit in regional offices waiting for procurement sign-off. They move from job to job together, so once one project converts, the whole company follows in months. By the time competitors caught on, Fieldwire was already the default in entire submarkets.
- No outbound sales. A small Google Ads budget did the work that a 10-person SDR team would have done at any other startup.
- Freemium over enterprise demos. Three free projects, no salesperson, no pressure. The product had to earn the upgrade.
- Field-first, not exec-first. While Procore courted project executives, Fieldwire built for the people actually swinging tools on site.
- Ignore Silicon Valley. Growth came from Atlanta, Canada, and other underserved markets that established players were ignoring.
The 100 days on his shoes
Why turning down easy money saved the company
By the time Fieldwire was gearing up for its Series A, the company had three months of cash left. Yves had “100 days” printed on a pair of custom Converse as a reminder. There was a bridge round on the table. Money he could have signed for that afternoon.
The valuation was bad. Not catastrophic, just bad enough to set a number that would haunt every future raise. Yves walked away from it, sat down with his co-founder Javed Singha, and they both went on half salaries to buy two extra months of runway. Then they raised a clean Series A.
From that round onwards, Fieldwire never had a single down month on revenue. Not one. The lesson sits underneath the entire story: taking the wrong money doesn’t save a company, it just makes the next conversation harder. There is a separate cluster of lessons we’ve pulled from founders who sold for millions, and walking away from bad capital is one of the most consistent patterns across all of them.
Me and my co-founder went on half salaries. That gave us an extra two months of runway, and we raised a great Series A. That’s the moment where the company could have died, and it survived.Yves Frinault, Co-founder and CEO, Fieldwire

How Fieldwire compressed an acquisition into a long lunch
The Hilti story didn’t start with a banker. It started with a McKinsey consultant calling Yves to say a tool company from Liechtenstein was in town and wanted to meet some startups. Hilti had never invested in a software company. They’d never acquired one. They were just curious. The McKinsey office was two blocks away, so Yves showed up.
The pitch deck Fieldwire walked in with was, by total coincidence, the deck Hilti would have written for themselves. Replace tools with software. Serve the craftsperson, not the back office. Even the last slide landed: a year earlier, Hilti had quietly shipped a measuring device with Fieldwire’s Android app pre-installed as the only third-party software on it. Neither company had made anything of it at the time. Hilti’s CFO sat through the demo and asked when they could work together.
Hilti took a position in Fieldwire’s Series B in 2017 and stayed close as the company scaled. When the conversation eventually turned from invest to buy, Yves refused to let it become a six-month process. He proposed four meetings. Two on vision, two on price. Two days in Liechtenstein, his co-founder dialed in from the US. Price agreed before due diligence even started. Six months later it closed at roughly $300 million, the curse cracked.
What Fieldwire actually changed about ConTech
The exit that rewrote the ceiling for everyone behind it
The number itself matters less than what the deal proved. ConTech could clear $100 million. It could clear $300 million. With the right wedge into the field, the right product instinct, and the patience to ignore Silicon Valley’s playbook, construction software was a real category, not a charity case.
Fieldwire was the third-largest ConTech acquisition at the time, behind PlanGrid (sold to Autodesk for $875M in 2018) and Levelset (sold to Procore for $500M in 2021). It sat alongside Aconex’s $1.2 billion sale to Oracle as proof that construction-native software could exit at scale, not just at the margins.
And the post-acquisition story is the part founders keep getting wrong. Most exits end the same way – the team scatters, the product gets absorbed, the brand quietly dies inside the acquirer. Fieldwire grew from around 130 employees at acquisition to 300+ inside Hilti, with full operational autonomy because Hilti had never bought a software company before and didn’t have a playbook to force on them. The product is still running. The brand is still Fieldwire. That, more than the price tag, is the real benchmark.
How Fieldwire compares to the other ConTech exits
The acquisitions that defined the category
| Company | Acquirer | Year | Price | Wedge |
|---|---|---|---|---|
| Aconex | Oracle | 2017 | ~$1.2B | Project collaboration / document control |
| PlanGrid | Autodesk | 2018 | ~$875M | Mobile blueprint access |
| Levelset | Procore | 2021 | ~$500M | Lien rights and payments |
| Fieldwire | Hilti | 2021 | ~$300M | Field task and punch list management |
| Consigli | AECOM | 2025 | ~$390M | AI for design and engineering |
For most of the 2010s, the prevailing VC view was that construction software companies couldn’t exit above roughly $100 million. The industry was seen as too slow-adopting, too fragmented, and too margin-thin to support venture-scale outcomes. The PlanGrid, Aconex, Fieldwire, and Levelset deals all broke that assumption between 2017 and 2021. (Source)
Hilti acquired Fieldwire for approximately $300 million. The deal was announced in November 2021 and closed in Q4 2021. Hilti had previously invested in Fieldwire’s Series B round in 2017. (Source)
Fieldwire was co-founded in 2013 by Yves Frinault and Javed Singha, who previously worked together at Ubisoft. Frinault is a Stanford-trained civil engineer and former French army paratrooper. Singha holds an MBA from Cornell. (Source)
The team didn’t have the budget, headcount, or culture for outbound sales. Frinault had run performance marketing at Ubisoft, so Fieldwire spent $3-5K a month on Google Ads, paired it with a freemium signup model, and let the product convert users itself. In 2013 there was almost no competition for ConTech keywords, which made the inbound funnel cheap and effective.
Fieldwire continues to operate as a division within Hilti under Frinault’s leadership. The team grew from approximately 130 employees at acquisition to over 300 within a year, and the company has retained significant operational autonomy. The product remains active and has been integrated into Hilti’s broader software portfolio. (Source)
Frinault structured the acquisition as four meetings – two on shared vision, two on price. The price was agreed before formal due diligence began, and the deal closed approximately six months later. Hilti had been an investor since the 2017 Series B and was already pre-aligned on the field-first thesis Fieldwire was selling. (Source)
