BlitzAPI vs SoloTools

Smart ICP Targeting & People Search

This feature allows your team to instantly find and prioritize ideal customer profiles with surgical precision. Beyond simple search, BlitzAPI's algorithm ranks and surfaces decision-makers based on your specific targeting criteria, ensuring your outreach efforts focus on high-intent, high-potential contacts from the very first API call. This intelligent prioritization eliminates noise and directs resources toward the prospects that matter most for your campaign's success.

Verified Email & Phone Enrichment

BlitzAPI provides direct access to verified, accurate professional email addresses and direct-dial phone numbers. The system is built on a foundation of deliverability, meaning every data point is validated for accuracy to maximize the success of your outbound communications. This ensures your sales and marketing teams can connect with confidence, drastically improving connection rates and reducing time wasted on incorrect or outdated contact information.

Advanced Catch-All Email Validation

A standout capability, this feature validates catch-all email domains (like @company.com) with over 98% accuracy in real-time. This solves a major pain point for GTM teams, allowing you to confidently identify which contacts at a target company are reachable and which are not. By eliminating guesswork, you preserve credits, protect sender reputation, and ensure your messages land in legitimate inboxes.

Unlimited Data Enrichment API

Scale your data operations effortlessly with BlitzAPI's flexible enrichment endpoints. Through simple, well-documented API calls, you can enrich contact records with comprehensive professional details, append company data, match LinkedIn profiles, and update information at any volume. This API-first architecture is built for reliability, allowing you to seamlessly integrate clean B2B data into any stage of your workflow, from lead capture to campaign execution.

Intelligent AI Proposal Generation

This is the core engine of SoloTools. It goes far beyond filling in template blanks. The AI writes original, persuasive content tailored to your specific project details. It constructs a full narrative, including a strategic executive summary, a logically broken-down scope of work, professional pricing tables, and clear terms and conditions. This feature evolves the user's process from manual drafting to strategic reviewing and refining, saving hours per proposal and ensuring a consistently high standard of communication.

AI-Powered Section-Level Editing

SoloTools provides granular control over the AI-generated content. For any section of the proposal—like the executive summary or scope—users can command the AI to refine it on the fly. With simple prompts like "Make more persuasive," "Make shorter," or "Rewrite in a formal tone," the AI instantly rewrites that specific part. This feature allows for rapid iteration and customization, ensuring the final document perfectly matches the desired tone and emphasis without starting from scratch.

Client Engagement & E-Signature Suite

This feature manages the entire client-facing journey after the proposal is created. Users can send proposals directly via email from the platform with a personalized message. They can then track when a client opens the proposal for the first time with real-time notifications. Most importantly, clients can review and provide legally-binding e-signatures directly within the proposal interface by drawing their signature, moving the deal forward seamlessly without external tools.

Proposal Analytics & Automation

This feature provides the data and automation needed to optimize your business development funnel. It tracks each proposal's status (Sent, Viewed, Accepted, Declined), giving you a clear view of your conversion rates and where deals may be stalling. Automation features include setting proposal expiry dates to create urgency and configuring automatic follow-up email reminders, so you never have to manually chase a client for feedback, allowing for more strategic follow-up.

Automating Outbound Sales Prospecting

Sales development representatives (SDRs) and outbound teams use BlitzAPI to build targeted prospect lists automatically. By integrating the People Search and Enrichment APIs into their CRM or sales engagement platform, they can trigger workflows that find, verify, and enrich leads based on firmographics, instantly creating a stream of sales-ready contacts for personalized outreach campaigns without manual research.

Building Scalable Lead Enrichment Pipelines

Marketing and RevOps teams implement BlitzAPI as the core engine for their lead enrichment processes. When a new lead is captured via a form or event, an API call automatically enriches that record with verified company data, direct contact info, and LinkedIn profiles. This transforms raw leads into fully qualified, actionable accounts, enabling faster lead routing, more personalized nurturing, and accurate segmentation for ABM strategies.

Executing Waterfall ICP Targeting Playbooks

Sophisticated GTM teams employ a "waterfall" approach to targeting. They use BlitzAPI to first target their primary ideal customer persona. Once that quota is met, the system seamlessly moves to the next priority persona, and so on. This ensures maximum efficiency in credit usage and campaign focus, allowing teams to systematically expand their reach while always prioritizing the highest-value targets first.

Maintaining CRM Data Hygiene at Scale

As contact and company data decays over time, BlitzAPI provides a systematic solution for data cleansing. Scheduled API jobs can run through existing CRM records to validate email addresses, update job titles and company information, and append missing phone numbers. This ongoing enrichment ensures sales and marketing teams are always working with accurate, up-to-date information, improving campaign performance and operational efficiency.

The Web Designer Securing High-Value Projects

A freelance web designer can use SoloTools to quickly generate detailed proposals for website redesigns. By inputting the client's name, project type, and a $14,000 budget, the AI creates a proposal with phases for Discovery, UI/UX Design, and Development. The designer uses the AI editor to make the executive summary more persuasive, then sends it via the platform. They track the client's views and secure an e-signature, all within a professional, branded workflow that justifies their premium rates.

The Marketing Consultant Scaling Client Onboarding

A solo marketing consultant juggling multiple clients needs to streamline onboarding. For a new SEO campaign, they use SoloTools to generate a proposal in seconds. They leverage the smart pricing suggestions to validate their rates, set a 14-day expiry date to encourage a prompt decision, and enable a 5-day automatic follow-up reminder. This systematizes their sales process, reduces administrative time between initial call and project start, and allows them to focus on strategy over paperwork.

The Independent Writer Proposing Content Strategy

A content strategist pitching a long-term blog and newsletter package uses SoloTools to structure a complex, multi-phase engagement. The AI helps articulate the value proposition and break down the deliverables into clear monthly sprints. The writer uses the section-level editing to ensure the tone matches the client's corporate brand. They share the proposal via a link for easy client access and use the view notifications to time their follow-up call perfectly after seeing the client has engaged with the document.

The Busy Freelancer Improving Win Rates

A generalist freelancer who frequently loses deals in the proposal stage adopts SoloTools to gain insight. They use the platform for all their proposals over a quarter. The analytics dashboard then reveals a pattern: many proposals are viewed but not accepted. This insight prompts them to refine their scope descriptions and pricing transparency within the tool. By A/B testing different AI-generated executive summaries, they systematically improve their proposal's effectiveness and increase their close rate.

What makes BlitzAPI different from other B2B data providers?

BlitzAPI is built as an API-first infrastructure product, not just a data vendor. We prioritize quality over quantity, with a deliverability-first model that ensures you pay primarily for verified, accurate results. Our architecture is designed to integrate into your existing GTM workflows seamlessly, offering flexibility and scalability that legacy tools often lack, all while providing superior accuracy, especially on challenging data points like catch-all emails.

How does the credit system work?

BlitzAPI operates on a transparent credit-based pricing model. You purchase a bundle of credits, and different API calls consume a set number of credits based on the complexity and data value of the request (e.g., an enrichment may cost more than a validation). This allows you to pay directly for the value you receive. Notably, we offer 1,000 free credits to start, so you can test the quality and fit within your own systems without any initial investment.

Can BlitzAPI integrate with our current tech stack?

Absolutely. BlitzAPI is built for integration with modern GTM ecosystems. It offers clean, well-documented REST APIs that can be connected directly to your CRM (like Salesforce or HubSpot), sales engagement platforms (like Outreach or Salesloft), marketing automation tools, and internal databases. This API-first approach means you can embed powerful data capabilities anywhere in your workflow without disruptive platform changes.

What is your data coverage and accuracy?

Our database covers over 360 million verified B2B contacts and 60 million enriched company profiles across major global markets. We maintain a greater than 98% email deliverability rate, which is a testament to our rigorous validation processes and real-time verification capabilities. Our focus on continuous updates and accuracy ensures you are working with the most reliable B2B data available.

How does the AI proposal generator work?

You provide the essential project details: client name, project type, budget, and key scope notes. Our advanced AI then analyzes this input and generates a complete, structured proposal document. It doesn't just fill a template; it writes original content including a tailored executive summary, a detailed breakdown of the scope of work, a professional pricing table, a proposed timeline, and standard terms and conditions, all in about 12 seconds.

Is there a free plan to try SoloTools?

Yes, SoloTools offers a fully-featured free plan designed to let you experience the core workflow. You can create and send up to three proposals per month at no cost, with no credit card required to start. This includes access to the AI generator, basic editing, and sharing via link. It's the perfect way to integrate the tool into your process and see the time savings firsthand before upgrading to unlock unlimited proposals and advanced features.

Can I edit the proposals that the AI creates?

Absolutely. You have full control over every part of the AI-generated proposal. You can manually edit any text field as you would in a standard document editor. More powerfully, you can use our AI section-level editing commands to instantly rewrite any section—like the executive summary or scope—by prompting it to be more persuasive, shorter, more detailed, or in a different tone, allowing for rapid customization.

How do clients sign the proposals?

SoloTools includes a built-in, legally-binding e-signature system. When you send a proposal to a client, they can review it in their browser. To accept, they click a button to draw their signature directly on the document using their mouse, finger, or stylus. Once signed, the proposal is marked as accepted, and both you and the client receive a finalized copy for your records, streamlining the approval process entirely within the platform.
