Leadbay
Leadbay is a Y Combinator (F25) B2B sales startup building a domain-specific AI model that discovers and qualifies small-to-mid-sized business leads that traditional platforms like LinkedIn, ZoomInfo, Apollo, and Clay can't find. Trained on market data, a company's own CRM/ERP history, and reps' instincts, Leadbay learns a team's Ideal Customer Profile and predicts who will buy next - delivering qualified leads directly inside agentic workflows and AI apps like Claude, ChatGPT, and Copilot. Customers in data-scarce industries such as construction, hospitality, manufacturing, and B2B services report roughly 3-5x more qualified prospects. The company raised a $4.3M seed round led by Y Combinator in May 2026 and is based in San Francisco.
Sailes
Sailes is a New York and Kansas City based AI company that builds autonomous, personality-driven "Sailebots" to automate the entire B2B sales prospecting lifecycle - from finding contacts and researching accounts to writing outreach and booking meetings. Founded in 2018 by Nick Smith, the venture-backed firm trained its own sales-focused AI model to replace roughly a dozen point solutions, and its Sailebots are deployed across dozens of countries for enterprise and mid-market sales teams at companies including Staples, Wiley, and Rogers Electric.
Regie.ai
Regie.ai is a San Francisco-based startup building an AI-native sales engagement platform that automates the grind of B2B outbound prospecting - sourcing leads, reading intent signals, writing personalized messages, and running email, phone, and social touches - while deciding on the fly whether an AI agent or a human rep should take the next step. Founded in 2021 by AI scientist Srinath Sridhar and sales veteran Matt Millen, the company pitches itself as a middle path between fully manual sales tools and fully autonomous bots, with a stated goal of amplifying human sellers rather than replacing them.
Revenoid
Revenoid is a San Francisco and Carrollton, Texas-based AI company that builds a 'system of intelligence' for enterprise go-to-market teams. Formerly known as EvaBot, the company pivoted from AI-driven corporate gifting to a suite of AI sales agents that continuously monitor thousands of accounts for buying signals, prioritize them with a pain-based scoring engine called UrgencyIQ, and automate account research, prospecting briefs, meeting prep and personalized outreach directly inside existing GTM stacks like Salesforce, HubSpot, Outreach and Salesloft. Founded by CEO Rabi Gupta, the company raised a $10.83M Series A led by Comcast Ventures in 2022.
Telescope
Telescope is an AI-driven lead generation and outreach platform that lets B2B sales teams describe their ideal customer in plain English and instantly surface matching companies and people from a database of 900M+ verified profiles and 50M+ companies. It then automates personalized outreach across email and LinkedIn, warms up mailboxes for deliverability, and consolidates replies into a single inbox - replacing a stack of separate prospecting tools. Founded in 2021 by Dr. Reza Javan and backed by Sequoia Capital and Entrepreneur First, the London-based company says it is used by 20,000+ companies.
Reza Javan
Reza Javan is the CEO and co-founder of Telescope, a London-based AI prospecting platform that automates B2B outbound across email and LinkedIn. Before he sold software to salespeople, he was Dr. Reza Rezaei Javan, an Oxford DPhil microbiologist who sequenced thousands of pneumococcal genomes and discovered new families of antimicrobial peptides. He swapped the lab bench for a startup at Entrepreneur First's LD17 cohort, where Telescope was born in 2021. The company is backed by Sequoia Capital, Soma Capital and Entrepreneur First.
Nooks
Nooks is an AI Sales Assistant Platform (ASAP) that automates the grind of outbound sales - parallel dialing, prospect research, call coaching, and follow-up - so reps can spend more time having real conversations and less time leaving voicemails. Founded by three Stanford classmates in 2020 and headquartered in San Francisco, the company has raised $70M, including a $43M Series B led by Kleiner Perkins, and counts Seismic, Greenhouse, Brex, Deel, and HubSpot among its customers.
Mei Siauw
Mei Siauw is the Co-founder and CEO of LeadIQ, a San Francisco-based B2B sales intelligence platform that helps sales teams prospect smarter and faster.
