About
Shelf.io is an AI-powered knowledge management company that provides an enterprise platform designed to surface accurate answers from an organization's distributed content — documents, wikis, PDFs, support articles, and other sources — to customer service agents, employees, and end customers in real time, reducing time-to-resolution and improving the consistency of information delivery. Founded in 2016 and headquartered in New York City, Shelf.io has raised more than $60 million and built a customer base spanning financial services, insurance, healthcare, and technology companies that need to make large knowledge bases reliably accessible across their service and support operations.\n\nShelf.io's platform ingests content from disparate sources including SharePoint, Confluence, Salesforce, Zendesk, and local file repositories, applies AI to index and classify knowledge, and then serves answers through a unified interface accessible to agents within their existing ticketing or CRM tools. A distinctive feature is MerlinAI, Shelf's answer engine that uses natural language processing to interpret agent or customer queries and return the most relevant knowledge articles rather than requiring users to navigate folder structures or formulate precise search queries. The platform also includes knowledge gap detection that identifies common queries for which no good answer exists, enabling content teams to fill coverage gaps proactively.\n\nShelf.io competes with Guru, Glean, Bloomfire, and Salesforce Knowledge in the enterprise knowledge management market. Its focus on contact center and customer service use cases, combined with deep integrations into the support tool stack and its knowledge gap analytics, differentiates it from general-purpose enterprise search or intranet knowledge base tools. The company positions its platform as the connective tissue between an organization's institutional knowledge and the front-line teams who need to apply it.
PerkUp is a YC-backed employee rewards platform combining peer-to-peer recognition, spot bonuses, and milestone gifting; recipients choose from a global catalog of gift cards, experiences, or Visa cards.
About
PerkUp is a New York-based employee rewards and recognition platform backed by Y Combinator and designed to help companies celebrate milestones, reward performance, and build culture across distributed teams. The platform combines peer-to-peer recognition, manager-driven spot bonuses, and automated milestone gifting—work anniversaries, birthdays, new hires—into a single employee experience layer. Recipients choose their own rewards from a global catalog of gift cards, physical gifts, charitable donations, or prepaid Visa cards, eliminating the mismatch of generic company swag that goes unused.\n\nPerkUp's catalog spans thousands of options across retail, dining, travel, wellness, and digital subscriptions, and is accessible in over 100 countries, making it a strong fit for remote-first and multinational teams. The admin dashboard gives HR and people ops leaders full visibility into budget consumption, recognition trends, and employee engagement signals. Automations handle recurring events like work anniversaries without requiring manual HR intervention, reducing program maintenance overhead while keeping the experience personal and timely.\n\nAs a YC alumni, PerkUp has grown primarily through product-led and self-serve channels, targeting startups and mid-market technology companies where people operations teams are lean but culture investment is high. The platform integrates with Slack, Microsoft Teams, and major HRIS systems, embedding recognition into the daily workflows where employees already spend their time. PerkUp competes in a crowded recognition market alongside Bonusly, Nectar, and WorkTango, differentiating on catalog breadth, international coverage, and the simplicity of its gifting automation.
