Sales Enablement Startups funded by Y Combinator (YC) 2026

Pulsent continuously watches how your users and interacts with your product and engages them at the right moment to convert, upsell, and retain. As companies scale, founders, account managers and customer success teams can only take care of a small fraction of users. The rest receive generic, annoying and poorly timed communication. Opportunities are missed, customers churn, and revenue is lost. The core problem is that user behavior is fragmented across tools like PostHog, Stripe, Salesforce, etc., making it impossible to understand users in real time. We unify all data into a single view and let AI agents act on top. This only recently became possible with advances in visual AI (dec ‘25), allowing agents to watch sessions and understand behavior at human or better level. Pulsent detects expansion and churn signals, prioritizes high-value accounts, and executes through AI agents across channels like email, LinkedIn, and WhatsApp. It increases conversion and reduces churn without adding headcount. We already have paying customers, process hundreds of millions of events daily, and are seeing strong demand from PLG B2B Clients. Nicolò is an ex-BCG who has scaled two startups to millions in ARR. Arseniy worked for several years at Datadog handling billions of datapoints. We’ve worked together for 3+ years and experienced this problem firsthand in our previous startup.

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.

Step 1: We find you warm leads: contacts + companies that are showing interest on your website (via 6sense/Clearbit) and researching you around the web (via Bombora) but haven't converted yet. Step 2: We then auto follow up via chat, email or LinkedIn. Depends what workflows you want to set up - we can AI chat with them on your website, auto AI email them via your sequence provider of choice, and/or auto AI linkedin sequence them. Your humans can verify everything before being sent too.  Outcome: 10x more outbound than a human SDR, 3x reply rates since they're warm and more booked meetings (results shown in ROI dashboard).  P.S. if you want to use humans: you can send 1-click warm intro requests via your network or live chat/video call them too.
