Piper vs Regie: Which AI SDR Should You Pick?

If you're weighing Agent Frank vs Piper vs Regie.ai, you're choosing more than an AI SDR. You're choosing which buyers get worked, and who does the work. I checked all three vendors' live pricing and product pages on October 9, 2026, and read what reviewers say about each.

Piper talks to buyers who come to you. RegieGO helps a rep prepare and send their own outreach. Agent Frank is Salesforge's AI SDR, and he runs email and LinkedIn outreach to buyers who haven't found you yet.

Two questions decide it for me. Which buyers do you need to reach, and who should send the messages?

Piper Overview: Qualified's Inbound AI SDR, Now Part of Salesforce

Piper is the AI SDR agent from Qualified, a company started by Salesforce alumni. Salesforce agreed to buy Qualified on December 17, 2025, and closed the deal on April 1, 2026.

Qualified says Piper turns inbound prospects into pipeline around the clock. Piper works the buyers who reach your website or inbox, not cold lists.

Core features

• Website conversations: Piper chats with visitors by text, voice, or video, and can show a short slide presentation.
• Email: Piper follows up with inbound leads and nurtures warm ones with content offers.
• Meetings: Piper books meetings during a chat, from website forms, or by email.
• Offers: Piper shows personalized content to each buyer and the wider buying committee.
• Slack: your team can collaborate with Piper directly in Slack.
• Platform: every plan includes AI SDR Agent Studio, Agent Spotlight, and Salesforce reporting.

Piper pricing

Qualified lists three plans for Piper: Premier, Enterprise, and Ultimate. None shows a price, and each one sends you to sales.

Qualified's Premier plan covers 1 agent profile, 250K monthly web sessions, and 2.5K monthly active email contacts. Qualified's Enterprise plan raises that to 2M sessions and 10K email contacts and adds MCP and API access. Qualified's Ultimate plan reaches 5M sessions and 24K email contacts, with a dedicated IP.

A pricing breakdown from Prospeo puts negotiated Premier deals at $40K-$50K a year. Treat that as an estimate, not a quote.

Who Piper is best for

Piper fits companies with heavy website traffic that run on Salesforce, and Qualified says over 500 companies have hired it. For turning website visitors into meetings in real time, Piper is the stronger pick, because Frank doesn't run website chat.

Limitations and what reviewers say

• Piper doesn't prospect. Qualified's own outbound page has reps send cold email through a tool like Outreach or Salesloft.
• Its pricing page shows no prices and no free trial, and every plan starts with a demo.
• Qualified's pricing page lists no LinkedIn channel, mailbox warm-up, or mailboxes to buy.
• Salesforce has said it will bring Qualified's technology into Agentforce, its own AI agent platform.

I couldn't find a critical Piper review to show you. Qualified has no Trustpilot reviews, and Piper scores 8.9 out of 10 on TrustRadius, where every review I read rated it 8 or higher.

The complaints that do show up are about the learning curve and customization. A G2-based summary on Dashly says Qualified's AI Studio takes weeks to master, and that its AI assistant widget and reporting dashboards offer limited customization.

Regie.ai Overview: RegieGO Features, Credits, and Limits

Regie.ai is a sales AI company whose product relaunched as RegieGO on August 25, 2026. According to UsagePricing, the relaunch replaced per-seat annual contracts with a free plan and self-serve pricing.

Regie.ai bills itself as an AI sales assistant for sellers. RegieGO is a workspace with built-in enrichment, email, dialing, and workflows, all run from one chat. Its site also says "nothing goes out under your name that you did not send."

Core features

• Agents: you prompt once, and agents handle sourcing, account ranking, call prep, and follow-ups, on a schedule if you like.
• Messaging: drafts learn your voice and your company's pitch, and each one gives the buyer a reason to reply now.
• Channels: email, phone, and LinkedIn run from one queue, but LinkedIn steps come to you as tasks to send yourself.
• Power dialer: parallel dialing from local numbers, with do-not-call checks before each call.
• Enrichment: contact data from several providers, billed only when it finds something.
• CRM: a built-in CRM, or a sync with one HubSpot, Salesforce, or Monday CRM account per workspace.

Regie.ai pricing

RegieGO Free costs $0 and gives each person 250 one-time credits, for up to 10 people. RegieGO Pro costs $49/mo, or $41/mo billed annually, for one person and 5,000 credits a month.

RegieGO Team costs $150/seat/mo, or $125/seat/mo billed annually, with 15,000 credits per seat and a two-seat minimum. RegieGO Enterprise is a custom quote that adds SOC 2 security and a dedicated account manager.

Research, drafting, enrichment, and dialing all use credits. Paid credits reset each period, and when they run out, work pauses unless the workspace owner turns on capped overage billing.

Who Regie.ai is best for

RegieGO fits solo reps, founders, and small teams who want AI to do the prep while they run every conversation. If phone is your main channel, RegieGO Pro at $49/mo is the cheaper start, because Frank doesn't make calls.

Limitations and what reviewers say

• A person sends every email and LinkedIn touch, so output still depends on rep hours.
• The pricing page doesn't say how many credits one prospect uses, so monthly costs are hard to predict.
• Regie.ai sells no mailboxes or warm-up; email goes out from your own connected account.
• RegieGO launched in late August 2026, so most public reviews describe the older Regie.ai product.

Regie.ai has no Trustpilot reviews, and it averages 4.5 stars from 18 reviews on Software Finder. Its 3-star reviews mention an agent that targets the wrong prospects, inaccurate job-title data, and a hard initial setup.

Agent Frank Overview: The Outbound AI SDR on the Forge Stack

Agent Frank is Salesforge's autonomous AI SDR. He finds prospects, enriches and checks their data, writes personalized email and LinkedIn messages, follows up, handles replies, and books meetings on your rep's calendar, 24/7.

Frank works in a complimentary Salesforge workspace on top of the Forge Stack. His mailboxes, warm-up, lead data, and outreach platform can all come from the same company, under one login.

Core features

• Auto-Pilot or Co-Pilot: Frank runs on his own, or drafts messages for you to approve first.
• 500M+ contacts: he prospects nonstop through Leadsforge and enriches data before outreach, with no CSV exports in between.
• Email and LinkedIn together: both channels run in one sequence, with unlimited email and LinkedIn senders.
• Conditional sequences: touchpoints change based on each prospect's behavior, pain points, and goals.
• Personalization: he pulls from each prospect's website, blog posts, and LinkedIn posts, in 9 tonalities and 21+ languages.
• Knowledge base: you upload brochures, docs, and your website, and Frank treats them as his source of truth.
• Goals and hours: choose click-outs, sending your meeting link, or receiving theirs, and set his hours by time zone.
• Primebox™: every email and LinkedIn reply lands in one inbox, tagged positive, neutral, or negative.
• Human help: a dedicated Account Manager and a shared Slack channel come with him.

The Forge Stack behind Frank

Before Frank sends, his mailboxes warm up for two weeks through Warmforge at no extra cost. You can bring your own mailboxes or add Megaforge, built for Frank, from $69/mo for 20 mailboxes that send about 300 emails a day in total.

Infraforge dedicated mailboxes start at $33/mo billed annually for 10. The same stack can also run three ways: your own team on Salesforge, Frank, or a Forge Expert agency.

Agent Frank pricing

Frank is priced per Active Contact: the prospects he's working on at any time in the month. His base tier covers 1,000 Active Contacts for $599/mo billed quarterly, or $499/mo billed annually, which works out to 2 months free.

He's a separate subscription from Salesforge's own plans. Salesforge Pro costs $48/mo ($40/mo annual) and Salesforge Growth costs $96/mo ($80/mo annual), for reps who run outreach themselves.

Frank's page says 2,000+ contacts a month works out to $0.25 per contact, and its savings calculator sets his $499 against $8,000 a month for a classic SDR. The free ROI calculator estimates what you'd save with Frank.

Who Agent Frank is best for

Salesforge says Frank fits B2B companies with $5K-$100K ACVs that sell to startups, SMBs, or mid-market buyers and target 3,000+ businesses. It also says he's a poor fit if you target Fortune 500 companies, rely on long RFP cycles, or close six- to seven-figure deals. In VAI Consulting's case study, Frank booked 3 calls within the first week after a pivot to a more focused ICP and aligned messaging.

Honest limitations

• There's no free trial or self-serve signup: Frank starts with a demo and a two-week warm-up.
• Mailboxes cost extra unless you bring your own.
• He works email and LinkedIn only; Salesforge lists no phone or website chat channel for him.

Head-to-Head Feature Comparison: Piper vs Regie.ai

I compared the three on seven areas that decide whether an AI SDR adds pipeline: who sends, deliverability, personalization, replies, pricing, integrations, and setup.

Who finds buyers and who sends the outreach

This is the biggest difference, and it follows the line between inbound vs outbound sales.

• Agent Frank: finds new prospects in a 500M+ contact database, then sends email and LinkedIn messages himself on Auto-Pilot. On Co-Pilot, you approve his drafts first.
• Piper: waits for buyers to visit your site or fill in a form, then chats, emails, and books meetings. Cold outreach needs a separate tool.
• Regie.ai: agents build and rank lists and draft the outreach, but a rep sends each email and LinkedIn touch. Its power dialer places the calls, and the rep talks to whoever picks up.

An agent that waits for visitors can only talk to people who already found you. Frank is the only one of the three that sends multichannel outreach to cold prospects without a rep pressing send.

This tutorial walks through Frank's setup and live campaigns:

Email deliverability and warm-up

• Agent Frank: every mailbox warms up free through Warmforge, and each mailbox's Heat Score™ should stay above 97. Megaforge spreads his sending across several email providers, so if one blocks him, the others keep sending.
• Piper: sends inbound follow-up email, and Qualified's Ultimate plan adds a dedicated IP. No warm-up or mailbox tools are listed.
• Regie.ai: sends from your own Gmail or Outlook, checks contacts before sending, and throttles volume. It sells no warm-up or mailboxes.

The Forge Stack also lets you mix Mailforge shared mailboxes, Infraforge dedicated IPs, and Primeforge Google Workspace and Microsoft 365 mailboxes, all from one login. UniteSync reached an 85.26% positive reply rate and a $2.86 CAC on Salesforge, Mailforge, and Warmforge. This email warm-up guide covers the basics.

AI personalization and research

• Agent Frank: writes from each prospect's website, blog posts, and LinkedIn posts, plus the knowledge base you upload, in 9 tonalities and 21+ languages.
• Piper: talks by text, voice, or video, draws on your Salesforce and other sales data, and can show slides or content offers mid-chat. Its Agent Studio includes coaching and guides that shape what Piper says.
• Regie.ai: learns your voice and pitch, spots a "why-now" signal such as new funding or a new leader, and drafts around it. Each draft shows the source behind its claims.

All three personalize. The difference is that Frank sends his messages himself on Auto-Pilot, while RegieGO's drafts wait for a rep.

Reply handling and meeting booking

• Agent Frank: email and LinkedIn replies land in Primebox™, tagged positive, neutral, or negative, even when a prospect replies from a different address. He books meetings on your rep's calendar, and Primebox™ also works on mobile.
• Piper: answers buyers in chat and email and books meetings mid-conversation. Qualified's Enterprise plan adds agent handoff, and your team can work with Piper in Slack.
• Regie.ai: replies arrive in your own inbox, and your calendar syncs into RegieGO. A rep sends each response, with drafts from RegieGO.

Pricing and how costs scale

• Agent Frank: you pay for Active Contacts, not seats, and you get unlimited email and LinkedIn senders.
• Piper: plans scale by web sessions and email contacts, from 250K sessions on Qualified's Premier plan to 5M on Ultimate. Every price is a quote.
• Regie.ai: costs scale with seats and credits. RegieGO Team needs at least two seats, so three reps pay $450/mo, or $375/mo billed annually.

Frank's cost tracks how many prospects you work, not how many people you hire. Add a fourth rep, and Frank's bill stays the same, while a fourth RegieGO Team seat adds $150/mo ($125/mo annual).

Integrations, compliance, and the wider stack

• Agent Frank: runs in Salesforge, which connects to HubSpot, Salesforce, Pipedrive, Attio, Clay, Zapier, and Make, plus an MCP server for AI assistants. The Forge CLI covers six Forge products from one tool, and Salesforge is SOC 2 compliant.
• Piper: built on Salesforce CRM, with 20+ other sales and marketing integrations, such as HubSpot, Marketo, Outreach, Salesloft, Gong, and 6sense. MCP and API access start on Qualified's Enterprise plan, and its trust page cites SOC 2 audits.
• Regie.ai: syncs one CRM per workspace (HubSpot, Salesforce, or Monday CRM) and pulls in Gong calls and Seismic content. SOC 2 is listed on RegieGO Enterprise.

Of these three, only the Forge Stack sells mailboxes, warm-up, lead data, an outreach platform, and an AI SDR from one company. Neither Piper nor Regie.ai sells mailboxes or warm-up at all.

Setup, support, and time to first send

• Agent Frank: you start with a demo, then a dedicated Account Manager helps you build his knowledge base, connect mailboxes, and launch after the two-week warm-up. You also get a shared Slack channel.
• Piper: you start with a demo and a price quote, and Qualified runs an implementation process plus a training site called Qualified University. Reviewers describe a learning curve.
• Regie.ai: you sign up free with a work email, connect your inbox, and start prospecting. Regie.ai says there is nothing to wire up first.

Agent Frank vs Piper vs Regie.ai Pricing Comparison

Frank's cost grows with the prospects he works, not your headcount. Piper's cost follows website traffic and inbound email volume, and RegieGO's follows seats and credits.

Watch two limits. Qualified's Premier plan includes 2.5K active email contacts a month, and RegieGO's paid credits reset each period instead of rolling over.

Here's one scenario: you want 1,000 new prospects worked each month by email, with LinkedIn touches.

• Agent Frank: $499/mo billed annually plus Megaforge at $69/mo comes to $568/mo, or $668/mo on quarterly billing. Frank does the sending and follow-ups.
• Regie.ai: RegieGO Pro costs $41-$49/mo for one rep, but that rep sends every email and LinkedIn touch. Regie.ai doesn't publish how many credits 1,000 prospects use.
• Piper: doesn't cover this job, because it doesn't prospect. You'd need a separate sequencer for the cold email, on top of a contract that third-party data puts at $40K-$50K a year.

Over a year, Frank on annual billing costs $5,988 before mailboxes, less than the low end of that Piper estimate. If you're weighing an AI SDR against a hire, read AI vs human SDRs.

Who Should Use Agent Frank, Piper, or Regie.ai

You might consider Piper if:

• Your website already draws heavy traffic, and Salesforce is your CRM.
• You want to convert inbound visitors in real time. Piper is the stronger pick here, because Frank doesn't run website chat, voice, or video.
• You can budget for a quote-based contract, which third-party data puts at $40K-$50K a year for Qualified's Premier plan.

You might consider Regie.ai if:

• You're a solo rep or founder who wants AI prep but sends every message yourself.
• Calling is your main channel. RegieGO's power dialer runs parallel calls from local numbers, and Frank has no phone channel.
• You want to start free, then pay $49/mo for one seat.

Choose Agent Frank if:

• You sell B2B at $5K-$100K ACVs to startups, SMBs, or mid-market companies, and you target 3,000+ businesses.
• You want new pipeline from cold prospects, with email and LinkedIn sent for you.
• You want replies sorted in Primebox™ and meetings booked on your calendar.
• You want deliverability handled, from free Warmforge warm-up to Megaforge, Infraforge, Mailforge, or Primeforge mailboxes.
• You'd rather pay per Active Contact than per seat, with the option to run the same stack with your own team or a Forge Expert agency.

Final Verdict: Which AI SDR to Choose for B2B Pipeline

Piper and Regie.ai both use AI to help build pipeline, but neither runs cold outbound by itself. Piper converts buyers who already reached your site, and Salesforce now owns it. RegieGO preps the work, and a rep still sends every message.

For new B2B pipeline, Agent Frank is the stronger choice. For $499/mo billed annually ($599/mo billed quarterly), he prospects, sends email and LinkedIn messages, handles replies, and books meetings, with Warmforge warm-up included free. Salesforge pitches Frank as a way to augment your sales team, so your reps take the meetings he books.

Here are two claims you can check. A year of Frank on annual billing ($5,988) costs less than the low end of the third-party estimate for Qualified's Premier plan. And VAI Consulting booked 3 calls within the first week after it moved Frank to a more focused ICP and aligned messaging.

Salesforge itself calls Frank a poor fit for Fortune 500 targets and six- to seven-figure deals. For $5K-$100K ACV outbound, he's where I'd start.
