Automated lead generation saves you an enormous amount of money compared to traditional methods of finding prospects; it is also much faster since it eliminates all the time-consuming manual processes involved in finding prospects. Rather than having to manually enter all of your contacts into a spreadsheet, write generic emails, or contact every possible prospect, automated lead generation uses artificial intelligence to search, evaluate and communicate with potential customers automatically with very little human intervention.

This is much more than simple email automation. An AI-powered lead generation system will autonomously determine which prospects are worthy of being contacted, how to contact them and pass only the warm leads to the sales team. In essence, artificial intelligence works 24/7 and has the potential to reach 5 to 10 times more prospects than a single human can.

There is no longer any question that the use of technology in this fashion will dramatically improve conversion rates because the bots involved can "talk to" prospects and "send emails" faster and with much greater accuracy than any person could.

Elements of the Solution

Apollo: A Complete Lead Generation Solution

Apollo is the largest and most comprehensive contact database available. It includes many different filters for searching for leads, such as industry, geographic region, company size, and technology used. All of the data matches the individual prospects, making it much more reliable than other contact databases.

In addition to being an enormous contact database, you can also access Apollo through its API, which makes it easy to integrate with your existing CRM or spreadsheets. Every single contact has information attached to it, e.g., Job Title, email address, telephone number, and Social Media Profile(s). This enables GPT-4 to personalize the contact using something more than a standard salutation; for example, the greeting might say, "Sergei, congratulations on your successful investment round!"

For example, regarding Cryptocurrency Investors, in only 15 minutes, we identified a list of 3,000 Investors with DeFi and Web3 tags. The first outreach campaign had a 12% response rate. This is four times the Industry Average.

GPT-4 is the AI Behind the Entire System.

GPT-4 is the brain behind this entire system. It creates unique custom text for each potential client based on the Company Information and Specific pain points for each client. For example, if your list consists of Fintech Startups, the bot will write about the speed of your Solution rather than the scale of your Solution.

This method is called Contextual Personalization, and it will increase your Response Rates by four times compared to a traditional template letter.

You can also give the bot specific roles; it might be "Write like a Sales Expert", "The goal is to identify a problem for the client" or "Use the Tone of a Friendly Consultant". The bot also conducts a conversation, i.e. it modifies its responses and behaves like a live human.

Telegram: a Platform for Conversations with Prospective Clients.

Compared to Email campaigns, Telegram is much quicker and easier to use for communicating with potential clients. Messages are sent and received in a matter of seconds, with an Open Rate of about 80%, which is three to five times more than Email. The interaction with the bots is also more dynamic here. The bot captures new users by asking a few general questions and directing their inquiries to the most qualified managers. This new type of engagement allows businesses to convert website clicks into live contacts at an increased percentage of 8%-23% compared to conventional email. The business owner will receive hot leads almost immediately after the user clicks start.

The bot also syncs with your database in co-real time and uses webhooks to capture all of your sent messages, lead responses and deal status changes within your database. If you are using Google Sheets to manage a smaller project, you can create a row for each lead, including the lead's name, company, email address, current status and the most recent contact date. However, when your database is larger, it is best to use SQL tools such as PostgreSQL or Supabase for analytics and triggers for real-time updates and alerts. The Apollo system has direct integrations with the most popular CRMs (HubSpot, Salesforce and Pipedrive) using APIs so that managers are always working with the most up-to-date information. As a result, there is less dead time: no more manual updates and faster deal cycles.

Apollo uses an advanced algorithm to collect and filter leads based on specific user-defined search parameters (i.e. job title, location, revenue, technology used). First, you create your parameters; then, Apollo will generate an initial list of leads. Apollo will filter the list again based on user activity and recent large-scale news events such as investments and management changes, yielding a shortlist of highly qualified prospects.

Apollo will automatically generate hundreds of unique emails and interaction scenarios by utilizing each lead's contact profile and a variety of customizable fill-ins (Lead Name, Company Name, Pain Point). Through the use of a model that can create a multi-stage conversation, from initial contact through demo scheduling or qualifying to handling unexpected occurrences, the company can create personalized email campaigns for their clients. Communication and interaction are made through the Telegram Bot API. The messages are tracked so that both delivery and response can be monitored through the Bot API, which generates additional response scenarios for each response on the fly using GPT-4. Campaigns using the Bot API can be created to scale as volume limitations allow, sending several hundred messages per hour.

Records of all interactions with clients are stored in the database and synchronized with CRM systems. Automatic alerts to managers of new leads, as well as automatic scheduling for potential meetings using Google Calendar or Calendly, significantly reduce the need for manual work and improve the efficiency of the sales process.

These use cases and testimonials illustrate the impact that AI has on B2B sales. In B2B sales, there is always a great deal of manual work that must be done to find, contact, and qualify prospects. AI can handle the initial phases of these tasks. For example, a SaaS company used AI to generate 840 leads in two months. Of those leads, 63 signed up for a demo, and of those demos, 18 signed contracts for an annual revenue of $470K, without the company adding any new employees. The conversion rate of these leads was 7.5%, compared to the average of 4% to 6%.

The second example provided in this article involves a digital marketing agency. Apollo, the AI technology used, segmented potential clients based on their traffic and created highly tailored offers for both SEO and social media. The results were a 34% response rate for the segmented list, which is five times better than traditional campaigns.

The third example is of an HR-tech startup that used a Telegram bot to search for HR directors, was able to account for the pain points of the clients, and quickly identified potential clients from their inquiries. In the first quarter after launching the Telegram bot, 22 companies became clients, with a total LTV of $18K.

Flexibility in Marketing Campaigns

Through the use of AI, companies can create Flexible Scenarios for Marketing Campaigns by targeting customer segments based on their activities, using A/B testing to determine which messaging performs best, and using Algorithms to dynamically optimize Campaign Offers. With multi-stage Campaigns having tailored offers, businesses can improve their Conversion Rates by 40-60% over single Event Emails.

Support and Nurturing Leads

As opposed to allowing Leads to fall through the cracks after transferring them to a Sales department and virtually ignoring them, AI Bots provide continual reminders regarding upcoming meetings while also sending out marketing material and providing fast answers to Frequently Asked Questions (FAQs). Managers of Long sales cycles will find AI Bots significantly reduce their workload by automating Follow-Ups and providing Personal Reminders. As a result, Clients will feel as though they are always being cared for 24/7, even though a Bot is actually providing the Service.

Combining Technical Aspects with Integration

The Apollo REST API and the GPT-4 OpenAI API REST API are two popular APIs commonly combined as part of Digital Engagement Strategies by Marketing Companies. The Apollo API provides an organized Lead List in JSON Format and can handle 200 requests per Minute (RPM) on paid plans, generating approximately 12,000 Contacts per Hour. The GPT-4 API functions via POST Requests and has a roughly 10,000 RPM Limit, allowing it to scale quickly when generating Messages. Therefore, Data collected from the Apollo API, such as Lead Information, will be sent to a Server, processed by GPT-4, and automatically uploaded back to the Database. The Lead Creation process for a single Lead takes an average of 2-4 seconds and, during this timeframe, hundreds of different Messages are being created at the same time.

Integrating Telegram Bots into CRMs and Databases

The Telegram Bot API is available for all Telegram Bots and allows Communication with Users via Messages, Buttons, and Inline Elements. The bot and the webhook create a lead in a CRM (HubSpot, Salesforce, Pipedrive) when a user interacts with it. The lead is transmitted to the bot through the webhook and created in real-time by the CRM. Notifications are sent to managers immediately. Through SQL/ORM, managers have access to the corresponding databases (PostgreSQL, MySQL or Supabase). The messages that are sent to the client are always associated with the client in the system, and the use of triggers automates managers' notifications and the updating of leads when a client responds.

Data Security/Privacy

All of the data transmitted between the bot and the webhook is securely encrypted using HTTPS. Keys and tokens used for authentication and encryption are securely stored in environment variables. To further limit access to this data, the databases are only accessible through a VPN connection or from certain specified IP addresses. Data stored in the databases is also encrypted with the AES-256 encryption method, and every time that data is modified, a record of the modification will be kept in the database (logging). The GDPR compliance policy allows users to request the deletion of their personal information stored in the database, which will typically take 12 months but may take longer depending on the volume of requests from users. Telegram bots are also protected by using a secret token mechanism for validation, which helps prevent spoofing by outside parties. Managers can further limit access to managers who have approved user IDs via a list.

Benefits/Differences vs. Traditional Lead Generation

Better Quality and Conversion Rates on Leads

Due to AI's ability to quickly eliminate from consideration any unqualified clients by asking the appropriate questions, the likelihood of converting a lead increases dramatically because the message(s) used to create a lead are personalized. The rapid response time to clients, increased levels of personalization and data enrichment of leads from various external data sources improve the likelihood of a response to a lead by 3 to 4 times compared to traditional lead generation methods, where hours or days can go by before interacting with a lead.

Cost and Time Reduction through Communication

One bot can replace 5-10 sales reps ($50K-$70K/yr) at a significant cost savings. The monthly subscription prices for Apollo ($99-$149) and Open AI API ($200-$500) become ROI on your first couple of closed deals. The time spent on client searches gets cut from a week to 30 minutes and generating 1000 messages now takes only 20 minutes. The qualification process occurs almost instantaneously through Telegram.

Frequently Asked Questions

Can I adapt this to other industries?

Yes! GPT-4 will learn the specific vernacular of any B2B niche within which you have defined your client persona and Apollo provides a simple way to filter the contacts you want to use in your outreach.

What is the technical set up to implement this?

  1. You will need accounts set up on Apollo, OpenAI, and a server starting @ $5/month. Ideally, you should use a relational database (example: Google Sheets, PostgreSQL) to store your client's data. You can set up everything in a couple of hours using ASCN.AI with no coding required.

How will GPT-4 train me with my company's tasks?

GPT-4 will use context training with a system prompt with roles and styles. To ensure accuracy, you can augment requests using data from your vector databases (RAG).

Conclusion and Next Steps

Cold calling, sending bulk emails, and manually processing leads is a dead end business model. The Apollo + GPT-4 + Telegram combo gives you the advantage of up to 10 reps working 24 hours a day, for 5% of what you would pay them combined!

Don't attempt to reach out to hundreds of thousands of contacts in one go; rather, start with a small sample (100-200 leads), run your workflow through ASCN.AI for 1 week, and see how your return compares and what size you can grow the process to.

If you require assistance in set-up, consult, and train, contact us. Your first immediate lead generation typically occurs in about a week or so and this is not simply a fad or trend; it will enhance your existing team's performance.
