Automatic Outbound

If a high-intent prospect leaves without converting, Alphie doesn't give up — it launches a personalized warm outbound campaign to bring them back into the funnel.

Identification

Up to 75% of visitors identified

real-time multi-source fusion
Why company-level wins

Most tools try to guess the individual person. The data for that barely exists, so they’re wrong more often than they’re right — and every wrong guess sends your rep, your content, and your outbound chasing someone who was never there.

Alphie answers an easier question with better data: which company is this? Company-level signals are far more reliable — and for a B2B sale, the company is what you actually need to know.

Then we stack the odds. Instead of one provider, Alphie queries several of the leading ones at once and fuses their answers in real time. Where one source is blind, another sees.

Founders and GTM leaders about Alphie

Don’t just take our word for it

Everyone’s building AI agents. The problem: most buyers don’t want to “talk to AI” when it matters — they want answers fast and a human when they’re serious. Alphie feels like the right hybrid: AI qualifies inbound leads instantly, routes the context to Slack/CRM, and gives humans a chance to engage before the lead cools off. The way they map ICP data to instant Slack alerts is the smoothest workflow I’ve seen in years. If you’re thinking about building your own lead scoring… I’d look at this first. Yura Riphyak and team have done an incredible job.

Weiting LiuFounder @Growster · prev. co-founder & CEO, Codementor & Arc.dev

Responding to a lead in under 5 minutes = 21x higher conversion. We all know this stat, so why don’t most startups deliver? It’s not a people problem — it’s a stack problem. This is exactly why we partnered with Alphie. It kills the lag at the top of the funnel: lead hits the site, they’re engaged in under 30 seconds — no queues. Catch the lead, measure the impact, adjust before the quarter’s cooked. That’s the loop most stacks promise but never deliver.

Danylo BorodchukCo-founder @Lopus AI (YC W25)

I’ve seen a lot of ‘AI for sales’ hype lately, but Alphie is solving a fundamental human friction point in the buying process. It’s the execution layer your inbound strategy has been missing.

Nicolas ToperCo-founder @Inboxbooster and Manticore

In a world of noisy automation, Alphie provides the precision required to engage leads at the exact right moment. If you’re serious about maximizing your inbound ROI, this tool is hard to beat!

Santiago AparicioFounding team @Vortex · Co-founder, Ontop (YC W21)

The most expensive lead is the one that visits your site and leaves without a trace. We’re using Alphie to ensure that never happens again. It’s the infrastructure we needed to bridge the gap between ‘browsing’ and ‘buying’.

Our story

Built by Y Combinator Alumni

Olena Vozna and Yura Riphyak sitting with Alphie

Olena Vozna, CPO

Alphie stands on seven years of building the inbound engine at YouTeam.

After YouTeam was acquired and Yura invited me to work on Alphie, our first instinct was to productize everything — an AI agent running the entire inbound operation end to end. Then we asked a simpler question: where do companies leave the most money on the table? The answer was conversion. Traffic you already earned, qualified visitors already on your page, leaving without a trace.

So we zeroed in on that one moment and decided to own it completely: identify the visitor, personalize what they see, route your team in while they're still on the page, follow up if they leave. And design it to be able to run completely autonomously — booking demos while you sleep.

Yura Riphyak, CEO

At my previous company, YouTeam (YC W18, acquired by Toptal), inbound was our unfair advantage. The talent industry is one of the most cutthroat markets there is — and we built an inbound operation that pulled more qualified traffic than companies a hundred times our size, making us one of the top websites for hiring engineers globally.

In 2020 we tried to take it further: identify every website visitor and engage them on the spot. Pre-AI, that meant Intercom, Zapier, and HubSpot taped together — plus a brutal amount of manual grind. I lost 16 pounds. One of our two sales reps quit. We simply couldn't research and qualify leads fast enough to keep up.

But every single qualified visitor we caught in the act became a customer.
