Broccoli (W22) is building an AI front office for home services businesses, answering calls, following up with leads, and booking appointments across voice and text.
Today, they serve more than 500 customers, are booking jobs at a run rate of over $1 billion a year, and expect to end the year at more than $60 million in ARR, up from zero just two years ago, after recently raising a $30 million Series B.
In this fireside, @call_broccoli's founders @abhishekjain25 and @adityaketkar join YC's @gustaf to share the long path to finding that business, from an earlier EV startup that never found product-market fit to visiting 140 contractors across the Bay Area to understand their biggest problems firsthand. They explain how embedding inside a plumbing company led to the first version of Broccoli, why answering missed calls became the wedge, and how AI could eventually reshape the work of technicians themselves.

Agent memory gets harder the longer a chat runs.
We wondered: how well does Observational Memory hold up at 100K, 1M and 10M tokens? So we ran it on BEAM, the long-term memory benchmark, with default settings.
Turns out it has the top published scores at 100K and 1M:

The bottlenecks in AI are moving beyond the models.
We’re excited about startups building the hardware, infra, financial systems, and specialized software to bring AI into the real economy, from factories and data centers to government and space.

The story of Broccoli is very close to me and it feels special to see them announce their Series A & B with Khosla Ventures today. I've known AJ and Adi since interviewing them for the W22 batch. They applied with something very different but were extremely resilient and never gave up. Broccoli was born when they arrived to SF in the spring of 2024. Here is their story:
Broccoli has raised our Series A and Series B, both led by @khoslaventures with @ycombinator
Home services deserves tech that works as hard as its people. We're just getting started 🥦🥦🥦

Congrats to @call_broccoli (W22) on raising $52M across their Series A and Series B!
Broccoli’s AI agents answer calls for plumbing, HVAC, and electrical companies around the clock, booking jobs directly into the scheduling software contractors already use and following up on open estimates.
After their EV startup stalled, @abhishekjain25 and @adityaketkar knocked on 140 contractor doors until a Sacramento plumbing owner gave them five minutes. They built the first product from her office in three weeks, and today she’s Broccoli’s COO.
More than 1,500 home service businesses now run on Broccoli, with over 10 million customer conversations handled and 2.5 million appointments booked.

One of the biggest lessons we learned from YC is to launch early.
You will never really feel ready, but the earlier you launch the better.

One of the most unexpected things about YC is how long we continue helping the founders. Even though we're generally the first investors, we're the ones still advising them 10 years later. I think it's because we're the investing analogue of old friends.

The Swedish Qualified Stock Option scheme is great and has since its establishment been a action in the right direction to make Sweden a leading global startup hub long-term
But the 3 year cliff set legally is batshit crazy

Replying to @gustaf
@gustaf (Y Combinator) sees voice agents land across wildly different categories, and he’s watched voice companies go from demo to multiple rounds. At VapiCon he’ll share what YC is seeing: how fast these companies grow, how pricing has shifted in 12 months, and why the biggest opportunity is still ahead.

The question is no longer whether cancer vaccines can work. It’s whether our system can get them to patients.

Candid Health (W20) is rebuilding the medical billing stack for healthcare providers, automating the work required to get claims submitted correctly and providers paid.
Medical billing is a $200–300 billion market, and much of it still runs on decades-old software and manual processes. Today, @candid_health serves more than 200 healthcare organizations, processes about $7 billion in claims each year, and recently raised a $120 million Series D to keep expanding into the broader healthcare market.
In this fireside, co-founder and CEO @nick_perry joins @gustaf to share how Candid went from manually reviewing every claim to building the automation layer behind the business. He also explains where AI and agents fit into medical billing, and why the goal is to prevent denials before they happen.

That the Communist hammer and sickle isn’t commonly regarded as evil and offensive as the Nazi swastika is a failure of education.
“Dear Italian students, who today take to the streets carrying flags with the hammer and sickle and wearing T-shirts emblazoned with ‘CCCP’,” began an open letter in Italian by Lithuanian expat Neringa Budryt.
“I would like to ask you a question: do you truly know what the symbols you carry represent? And do you know what would have happened to many of you had you openly demonstrated in countries living under the oppression of communist regimes?
Let me tell you something. It is easy to display a red flag when, for you, communism is merely an abstract idea of equality, social justice, and rebellion against the system. It is easy to wear a T-shirt with "CCCP" on it when you have never experienced the reality of a communist regime.
We come from that part of Europe where communism was not a T-shirt, a symbol of rebellion, or a romanticized notion of equality. It was the system in which we lived—a system we never chose.
We know the history of Soviet repression, Stalinist purges, the Gulags, and mass deportations. Above all, we know the word "Siberia"—a place to which thousands of innocent people were forcibly deported, simply for thinking differently.
In Siberia—amidst freezing cold, starvation, and forced labor—many lost their lives; those who survived carried the scars of that experience forever. Entire families were torn apart, and generations were denied the chance to live freely in their own homeland.
In the countries of the Soviet bloc, censorship, political police, surveillance, and the suppression of dissent drastically curtailed individual freedoms.
We grew up in a system where state control permeated even our daily lives. At school, we were required to wear the red necktie of the "Pioneers." We were monitored; they tracked where we went and even whether we attended church. Even faith—a choice that should belong to an individual’s own conscience—could become a cause for suspicion.
We used to celebrate Christmas with our windows blacked out, to ensure no one would see us and report us. Because it was forbidden—just like so many other things: jeans, rock music, and all the symbols of a Western lifestyle. My mother returned from a Soviet labor camp. And do you know what happened to her? She was barred from continuing her education because she had been labeled an enemy of communism.
Under a communist regime, you could not protest. You risked arrest, imprisonment, interrogation, persecution—and, in certain historical contexts, even death. In the Soviet Union and other communist regimes, political dissent could cost you your freedom and your life.
Demonstrations independent of the authorities were not a guaranteed right; they were often suppressed by force.
That is why it strikes me to see young Italians proudly displaying the hammer and sickle—symbols associated with regimes that persecuted and imprisoned millions of people.
Today, you are free to take to the streets, shout against the government, criticize institutions, and wave your flags precisely because you live in a democracy that grants you these freedoms. Under an authoritarian regime of that kind, protesting against those in power could have landed you in prison.
This is not about denying the existence of social injustices, inequalities, or the right to fight for a better world. You are free to take to the streets to demand a more just society—but you should not idealize a system that denied so many people the very things you are free to exercise today: the right to choose, to believe, to speak, and to dissent. Before wearing a T-shirt with "CCCP" on it, listen to those who experienced that world. Talk to the deportees and their descendants; read the accounts of those who endured the gulags and forced exile to Siberia. Learn what it meant to be stripped of your freedom, your home, your loved ones—and even any prospect of a normal life—simply because of your background or your beliefs.
Before waving the hammer and sickle, please, study history thoroughly.”
