OpenFunnel is the Search Engine for GTM. Searching for "B2B SaaS, 501-1000 employees, uses Salesforce" - is just targeted spam. Even if you get creative with LLMs to query these databases, everyone has access to the same commoditized databases, these databases lack insights about right timing or pain-points prospects face. OpenFunnel is a time-aware search engine for insights and activities in your target segment - that reveal pain. You can search for activities like: "Find companies looking to implement usage based billing" "Find companies that moved from OpenAI to self-hosted models in the last 3-6 months" "Find companies who updated their pricing page to introduce an enterprise plan in the last 3 months" OpenFunnel continuously monitors these time-based signals, delivering actionable insights daily - so you have the fastest, unique insights that your competitors miss out on. Over 1000+ users are already discovering prospects through pain-first search, including some of the fastest-growing companies like Central, Mintlify, and Everest Systems.

Seals AI

Sales

Seals is a suite of AI Employees for Wholesalers & Distributors. Instead of relying on humans to quote, take orders, collect payments, place purchase orders and enter data into ERPs. We build AI Employees that do these manual repetitive tasks for the 700k wholesalers in the US. We’re a team of three Computer Science majors, and Fernando launched and grew AT&T in Mexico to $120M ARR. Previously, we all worked together at our last YC-backed startup, building it to over $6M in revenue. It was there that we placed thousands of purchase orders with wholesalers. We realized that almost every physical product comes from B2B sales in the supply chain. However, it turns out that most of these operations are still done manually through phone and email, involving tasks like quoting, taking orders, collecting payments, entering data into ERPs, and providing support. By automating these tasks with AI agents in a human-like manner, we are creating a massive opportunity to convert $100B of payroll expenses into software spending.
