We solve your problems
No idea who talked to which customer?
In a small team, everyone talks to customers — but no one logs the calls. Allo records and summarizes every conversation automatically. The whole team sees what was discussed, promised, and needs follow-up.
Using personal phones for business calls?
Your team shouldn't give out personal numbers to customers. Allo gives everyone one shared business number that works on their own devices. Customers see your company. Your team keeps their privacy.
Looking like a scrappy startup when you're not?
First impressions matter. Allo answers with a professional greeting, routes calls intelligently, and handles after-hours inquiries — so you sound like an established company, even if you're five people in a co-working space.
Calls going to voicemail while you're shipping?
When the whole team is coding, in meetings, or focused, calls pile up. Allo's AI receptionist answers every call, takes detailed messages, and routes urgent ones to available team members. Nothing falls through the cracks.
