They find customers who already want to buy.
Two Michigan grads. One Bollywood dance team. An AI platform that reads the entire internet to tell your sales team exactly who to call next — and why now.
Most co-founder stories start in a dorm room or a hackathon. Kishan Sripada and Vihaar Nandigala met on a Bollywood dance team sophomore year at the University of Michigan. One built choreography software. The other sold a restaurant tech startup at 19. Together, they built something different.
Both watched, up close, what bad sales targeting does to a business. Kishan had worked at Ramp — one of fintech's fastest-growing companies — and noticed the edge case: Ramp's real growth wasn't gimmicky email sequences. It was finding exactly the right companies at exactly the right time. Vihaar had sold his first company, KitchenKonnect, and later worked at J.P. Morgan, watching how much time and money evaporates chasing the wrong prospects.
The insight crystallised: the problem isn't the pitch. It's the list. Sales teams drown in noise not because they lack effort, but because they lack signal.
"Sales teams don't struggle with effort — they struggle with timing. We help them find customers who already have the problem they solve."
— Kishan Sripada & Vihaar Nandigala, Co-Founders, Orange Slice AIThey applied to Y Combinator as college seniors. YC — famously biased toward founders who drop out — told them to finish their degrees and apply again. They did. They were accepted into the Summer 2025 batch while spending most of their final semester building Orange Slice. That's the kind of thing that either ends badly or becomes a founding myth. This time: founding myth.
Kishan and Vihaar meet on a Bollywood dance team. A co-founder relationship begins.
KitchenKonnect — a restaurant tech company — is sold. Lesson learned: the product isn't the hard part. The customer is.
At fintech rocket Ramp, Kishan sees firsthand that growth lives or dies on targeting — not tone.
Applied to YC as seniors. Told to finish their degrees. Applied again. Accepted into YC Summer 2025 — while still in class.
Part of the Summer 2025 cohort — one of the most AI-heavy batches in YC history. Orange Slice launches publicly.
Co-led by 1984 Ventures and Moxxie Ventures. Paul Graham (YC) joins as angel investor. 5,000+ customers on the platform.
Think of it as a spreadsheet that has read the entire internet and knows which companies are quietly signaling that they need exactly what you sell — before they pick up the phone.
Describe your ideal buyer in plain English. "Find me 50 Series A fintech companies in NYC that just hired a Head of Sales." Orange Slice goes and finds them — enriched, researched, export-ready.
Upload your list. Get back firmographics, technographics, verified emails, headcount, revenue range, tech stack — all pulled live from multiple sources simultaneously.
Chat with your pipeline. Ask what deals are at risk this month, get account summaries, draft follow-ups — without ever opening Salesforce or HubSpot manually.
Score inbound leads by intent signals — not just form fills. Flags the 80+ scorers for your AEs. Routes the rest to nurture. Automatically.
Build durable, engineered GTM workflows. Checkpoints, retries, observability. Revenue ops that doesn't silently break on a Tuesday night.
Every column in the spreadsheet is code. Describe it in chat — Orange Slice writes the TypeScript, creates the columns, runs across thousands of rows. 100+ enrichments built in.
Orange Slice built custom crawling and scraping infrastructure that detects intent signals other tools miss entirely. Not broad filters. Specific, niche, industry-specific buying signals.
Court dockets. Litigation filings. Case volume spikes. If a law firm's caseload is scaling, they need your legal-tech product now — not next quarter.
Building permits. Planning applications. Construction activity. A developer filing permits today is a buyer of proptech within six months. Orange Slice knows before your competitor does.
Freight brokerage listings. Carrier capacity signals. Load board activity. If a logistics company is moving more loads, they need better software. Orange Slice flags them first.
"We can do this for any signal. Think of companies that have a CEO who ran track at Harvard. Or companies that have a VP of Sales that only has four fingers."
— Orange Slice founders, on the absurd depth of their signal libraryThat last example is more than a joke. It demonstrates the philosophical core of the product: if a buying signal exists somewhere online — in a niche forum, a public record, a job posting, a LinkedIn bio — Orange Slice can find it, structure it, and score it. The constraint isn't imagination. It's that most sales teams still rely on filters that were designed in 2015.
The builder who danced his way into a startup.
Kishan is a full-stack engineer who bootstrapped FORMI — choreography software that scaled to over 100,000 users and was adopted by Broadway productions, Disney, and NBA teams. That's not a CV line. That's evidence of a founder who can build a product from zero and find product-market fit in a market no one else was thinking about.
He then interned at Ramp for a year as a front-end engineer, followed by a year at Tour (a YC S21 company). At Ramp, he ran growth experiments that taught him the most expensive lesson in B2B sales: the email isn't the problem. The list is.
At Orange Slice, Kishan leads the technical architecture — building the scraping infrastructure, SDK, and AI agent systems that power the platform.
Sold his first company at 19. Built a second one at 23.
Vihaar Nandigala is the kind of founder who makes other 23-year-olds feel slightly unproductive. He sold KitchenKonnect — a restaurant technology company — at 19. He co-founded BitBasil. He worked as an analyst at J.P. Morgan. He then came back to startups, because apparently that's what his brain prefers to do.
At J.P. Morgan, Vihaar saw enterprise sales from the inside — how deals get made, how prospects get qualified, and how much time and money organisations spend on leads that were never going to close. The waste was staggering. The solution was obvious in retrospect: find customers who already want what you sell.
At Orange Slice, Vihaar leads the go-to-market strategy, fundraising, and overall direction of the company.
The seed round closed post-YC Demo Day. Led by two firms that know the difference between AI theatre and AI substance. Paul Graham — the person who wrote the playbook on finding great founders — joined as an angel. That's not nothing.
Orange Slice is using the capital to hire top engineering talent and scale its infrastructure. Not to rent a fancier office. That tracks.
More than 5,000 sales and RevOps teams are already on the platform. Early confirmed customers include Oracle, Confido Health, Pirros, and Glass Health. Pirros — also a YC S25 alumnus — published a case study on the platform.
"Top companies like Ramp solve this with dedicated growth engineers building internal data workflows. We're making that same capability accessible to everyone else."
— Orange Slice founding pitch, Y CombinatorThe insight is elegant in its simplicity: previously, only the biggest, most well-funded B2B companies could afford to run sophisticated signal-based prospecting. Orange Slice democratises that infrastructure. Now a 10-person startup can run the same playbook as Ramp.
The platform connects natively with Salesforce, HubSpot, Attio, Slack, and Gmail. It pulls data from OpenAI, Google Maps, Firecrawl, PredictLeads, Apify, and multiple contact-enrichment providers — simultaneously, in dependency order, without the user having to orchestrate any of it.
The co-founders met at University of Michigan on a Bollywood dance team. Not in a CS class. Not at a startup event. On a stage. That's either a great omen or a great anecdote. Probably both.
Most YC lore involves dropping out. Orange Slice got the opposite advice — finish your degrees, then reapply. They did. They built the product during their final semester anyway. YC accepted them. No one is surprised.
FORMI — choreography software — was adopted by Broadway, Disney, and NBA teams. He was a solo founder. That's an origin story that makes Silicon Valley's "disruption" obsession look a bit pedestrian.
In a sea of tech names that sound like they were generated by a random syllable machine, Orange Slice named itself after a snack. The logo is clean. The name is memorable. Sometimes the obvious answer is the right one.
Orange Slice's core product is technically described as "a spreadsheet where every column is TypeScript — and AI writes it for you." The spreadsheet metaphor isn't a concession to familiarity. It's a design choice that strips away complexity.
When Paul Graham writes a personal cheque into your seed round, something is being communicated. He's seen thousands of founders. He backed this team specifically. That is a data point worth paying attention to.
Orange Slice turns the tedious groundwork of sales research into something that happens while you sleep. In practical terms, here's what a sales team or RevOps professional can do with the platform:
Generate targeted lead lists using plain English prompts. No Boolean search syntax. No manual filtering. Type what you want, get a researched list in seconds. The AI reads the web, understands context, and structures the output.
Enrich existing lead lists with live data. Upload your CSV of companies and come back to it enriched with firmographics, technographics, verified email addresses, headcount, revenue estimates, and tech stack information — all from live sources, not stale databases.
Detect buying signals before your competition. The platform scans job boards, press releases, social media, company websites, news articles, court records, building permits, and niche industry sources to spot companies actively in-market for a product like yours.
Manage your pipeline through conversation. Ask Orange Slice which deals are at risk, which leads scored above 80 this week, or which prospects haven't been contacted in eight days. It queries your CRM and tells you — without you having to build a dashboard.
Build automated revenue workflows. Define multi-step GTM processes — inbound routing, lead scoring, CRM updates, Slack notifications — and run them as durable, observable pipelines. If a step fails, it retries. You don't have to fix it manually at 11pm.
Integrate with your existing stack. Salesforce, HubSpot, Attio, Slack, Gmail — Orange Slice connects to the tools your team already uses. The data flows in and out. No rip-and-replace.
Write custom enrichment logic in TypeScript. For teams with technical resources, every column in the Orange Slice spreadsheet can be a custom TypeScript function. The platform has a fully-typed SDK with 100+ built-in enrichments. Describe it in chat; the AI writes the code; it runs at scale.
Orange Slice is actively looking for top engineering talent. If you want to build the infrastructure layer of B2B sales for the next decade, they are the place.
VIEW OPEN ROLESOrange Slice is early. They've raised their seed, they've got 5,000+ customers, and they have a product that demonstrably works. What comes next is the harder game: scaling from a promising startup to a category-defining platform.
Here's what they're building toward — and where opportunity lies:
The bet is clear: the cold email era is ending. The winners of the next decade of B2B sales won't be the teams with the best templates or the most sends. They'll be the teams who know exactly who to contact, exactly when to contact them, and exactly why that person is likely to buy — before the competitor even knows the lead exists.
Orange Slice built the infrastructure to make that possible. The question is which companies will adopt it first — and whether yours is one of them.
