Orange Slice is a two-person YC startup building what its founders call "Claude Code for GTM" — an agentic sales enrichment spreadsheet that bundles lead generation, data enrichment, and workflow automation into a single conversational interface. Agents scrape custom data sources to surface high-intent prospects, and sales reps can approve, enrich, and route leads without ever leaving the chat. At $20/month for the starter plan, it dramatically undercuts enterprise sales intelligence incumbents like ZoomInfo or Apollo. The product's strength is its automation depth. Rather than static databases of contacts, Orange Slice builds enrichment pipelines that pull live signals — job changes, funding announcements, product launches, hiring patterns — and surfaces prospects who are demonstrably in-market. The agentic architecture means the system learns which signals predict conversion for your specific ICP and prioritizes accordingly. Founded by Vihaar Nandigala (who sold a company at 19 and joined J.P. Morgan) and Kishan Sripada (who bootstrapped FORMI), Orange Slice raised a $5.3M seed round from YC and is now getting its first major public exposure via a strong Product Hunt launch today at #2.

Reviewer scorecard
“Live signal-based enrichment versus static databases is the right architecture — stale contact data is the bane of every outbound motion I've seen. The agentic spreadsheet interface is genuinely novel. At $20/mo it's essentially free to test, which removes all the friction from trying it.”
“No API to speak of. It's a publishing platform, not a developer tool. Built-in audience is the value proposition.”
“Two employees, $5.3M raised, and a product that scrapes data at scale is a regulatory timeline waiting to happen — GDPR, CCPA, and LinkedIn's ToS are landmines. 'AI finds leads while you sleep' is also a promise every sales tool has made for a decade. Show me the actual conversion lift data from real customers, not a Product Hunt launch day.”
“10% revenue share is expensive at scale, but the built-in discovery and reader network provide real value.”
“The spreadsheet as the universal interface for agentic work is a compelling bet — it's the one tool every business user already knows. Orange Slice is proving that you can wrap complex AI pipelines in a familiar container and get adoption. The 'Claude Code for GTM' framing is exactly right — agentic tools for every business function.”
“For solo creators and freelancers doing their own business development, this fills a real gap. Getting live intent signals about who's actively looking for your services — without paying $500/mo for an enterprise platform — is genuinely useful. The conversational interface lowers the barrier to actually using it consistently.”
“The simplest way to start writing and getting paid. The network effect brings readers you wouldn't find elsewhere.”
