Enfolo is the memory layer for your business relationships, built for people who meet at trade shows, conferences, exhibitions, networking events, and sales meetings. After a busy event you still have everyone's card. What you've lost is the context: who someone was, where you met, what you discussed, what you promised, who needs urgent follow-up. Enfolo captures that memory in seconds, mid-conversation: scan, speak, move on. Then the memory goes to work. Enfolo researches every contact and company, builds a living timeline of each relationship, and turns your notes into personal follow-ups that actually happen, so no warm lead goes cold.

LinkedPhone gives small businesses, solopreneurs, and growing teams a professional business phone number and communication system — without a second SIM card or expensive hardware. Our app brings call routing, 24/7 live AI receptionist, voicemail transcription, texting, ticketing, and team-based customer communication to entrepreneurs across the US and Canada who've historically been underserved by legacy telecom providers built for large enterprises, not small ones. We've grown to a profitable, lean team serving thousands of small business customers — proof that there's real demand for communication tools built specifically around how small businesses actually work. Here's the hard problem we're solving right now: we've built a strong product and a loyal customer base almost entirely through word of mouth and product quality — and we've never had a dedicated marketing function. That's where you come in. We're hiring our first growth marketer to build the acquisition and marketing playbook from zero: figuring out which channels actually work for reaching US/Canada small business owners, running the experiments, and turning what works into a repeatable system. You'll work directly with the founders, with real ownership over how we grow — not executing someone else's marketing plan, but building the plan itself.
