It’s a strange problem for a startup: your users love your product too much. But that was the exact dilemma Harsha Gaddipati and his team at Slashy faced.
“Slashy is an AI-native email client and assistant that drafts replies in your tone, lets you know when you get an important email, and makes sure you never drop the ball on anything,” Harsha explains. But it didn’t start that way. Initially, Slashy was built as a general agent—an open-ended AI assistant similar to Claude’s computer use or Manus.
“We had 10,000 users, and stuff was going well,” Harsha recalls. “But then we kind of had to pivot because people loved the product too much.” The issue was how they loved it. Users viewed Slashy as their ultimate fallback: whenever ChatGPT or Claude failed to solve a problem, they would turn to Slashy.
“The problem with that is that as ChatGPT gets better, they use Slashy less and less,” Harsha says. “Even if in their heads they’re like, ‘Slashy is the best agent ever,’ it doesn’t work out well because that TAM [Total Addressable Market] just keeps decreasing.”
Owning the Interface for Work
To survive, the team had to figure out where users go before they even think about opening an AI chat interface to get things done. The answer was right in front of them: email.
“You go to your email to find work to do,” Harsha notes. “That’s fundamentally the reason you check Gmail 20 times a day. It’s not because you’re addicted to the Gmail UI. It’s because you’re wondering: did something important come in that I need to attend to?”
By owning the email interface itself rather than building an external agent, Slashy positioned itself to ride the wave of AI advancement instead of being crushed by it. “By owning that interface, we feel it is much more powerful and allows us to have a TAM that increases as AI gets more powerful, not decreases,” Harsha says.
The pivot happened in October 2025. Over the next six months, the team of just three worked to build a completely new email client from scratch. It was a massive technical undertaking. For comparison, Superhuman took two years and 12 engineers to build its initial product. Thanks to AI assisting their development, the Slashy team launched self-serve in May 2026.
Simplicity and Human-First Design
For Harsha, differentiation isn’t just about throwing more AI features at the inbox. It’s about completeness and understanding how humans actually work.
“We don’t just focus on AI,” he says. “We are trying to make a next-generation email client, not just a new AI agent to handle your email.”
That means sweat-the-details features that most three-week-old AI wrapper startups miss: native BCC, robust keyboard shortcuts, and Outlook calendar integration that auto-adds invites.
It also means rethinking how drafts are generated. Standard drafting tools look only at the text of the email thread, producing dry, generic responses. Slashy’s drafting engine mimics the research a human assistant would do. “A human actually looks at their profile picture, looks at their LinkedIn profile, does a web search, or looks at emails from other people at the same company,” Harsha says. “By going from those principles, it’s a lot easier to build high-quality AI, especially in such a human arena as email.”
Rather than hardcoding rigid roles, Slashy categorizes emails into three behavioral tiers:
- Tier 1 (High Priority): Emails you would never let someone else write (e.g., signing a contract or hiring). These require a human review before sending.
- Tier 2 (Transactional): Emails where you just need to get the point across (e.g., follow-ups after an interview, or asking a bank for account status). This is where Slashy’s auto-drafting and auto-sending features shine.
- Tier 3 (Spam & Noise): Emails that can be read later or ignored entirely.
To capture Tier 2 workflows, Slashy integrates with popular note-taking tools like Granola, Fathom, and Fireflies. If a founder notes “send candidate resume to team” during a call, Slashy automatically drafts the email and files the follow-up, removing the delay between meetings and execution.
SaaS is Far From Dead
With the rise of generative AI and AI coding tools, there is a common refrain in San Francisco that SaaS is dead because software has become trivial to replicate. Harsha strongly disagrees.
“I think SaaS from the standpoint of ‘you can push one piece of code and never update it’ is dead, but I don’t think that’s ever been alive,” he says. “People always paid for SaaS not because of a static feature set. The whole joke is Calendly is so easy to build. The reason you pay Calendly is because you trust those people to make the best booking software known to you, and that they’re constantly improving it.”
Slashy launched its monetization model with no free tier—pricing starts at a minimum of $30/month. The growth has been driven by a mix of inbound referrals, outbound outreach, and paid ads.
“For prosumer products, price is just another feature,” Harsha explains. “You’re getting people who are in the top 5% to 10% of earners, and they’re spending an hour or two to learn your product. Two hours of their time is worth more than $20 or $30. It’s never been about the money; it’s about time and trust.”
Hiring Nice, Obsessed Builders in SF
The team is currently small: Harsha and his co-founders, one front-end intern, a designer contractor, and one person in the founder’s office. They build strictly in-person in San Francisco, working long hours, and are looking to hire design engineers.
Harsha uses the term “Design Engineer” intentionally. “If we just say designer, it can mislead people into thinking they’re only going to do Figma mockups,” he says. “We want them to get coding. We want people who understand UI/UX flows but will also get into the actual code and ship features.”
Culture-wise, Harsha values two traits above all: niceness and obsession.
Niceness, he argues, is a prerequisite for building a critical infrastructure product like email. “When we started off, we weren’t as reliable as Gmail. We had to have early users who were nice enough to give us a chance. If we aren’t nice ourselves, we are hurting the culture that let us exist in the first place.”
Obsession is what defines the team’s engineering standards. “Startups are hard, and on a good day, 20 things will break because the quality standard for email is so high. People use it for two to three hours a day,” Harsha says. “We look for people who make work that is of such high quality that you ask: why are they working for us and not doing their own thing?”
When selling candidates on the opportunity, Harsha takes a refreshingly honest approach. He avoids overselling their 200% month-over-month growth metrics or their upcoming funding rounds.
“At some point, those numbers will get bad, and we’ll have to make strong decisions. I don’t want people who only want to come in when numbers are good,” Harsha admits. “I’d rather have people who trust that me and my co-founders are the right people to make those decisions. If you don’t believe that we will be one of the defining companies in SF for the next five years, it doesn’t make sense to join us.”
