Feature Comparison

BlitzAPI

This isn't your grandma's search engine. BlitzAPI's algorithm doesn't just find people; it ranks and prioritizes them based on your ideal customer profile. You get the decision-makers you actually want, instantly, without sifting through a mountain of irrelevant noise. It's like having a targeting system for your prospecting.

Verified Email & Phone Enrichment

Stop sending emails into the void. BlitzAPI hooks you up with verified, accurate work emails and direct phone numbers. The magic is in the verification—it's built with a deliverability-first mindset, meaning the data actually works when you use it. No more bounces, just connects.

Catch-All Email Validation (The Game Changer)

Catch-all domains (like @company.com) are the final boss of email validation, and BlitzAPI beats it with >98% accuracy. It validates these in real-time, so you never have to guess if an email is real or just a black hole for your credits. This feature alone saves budgets and sanity.

Unlimited Data Enrichment API

Enrich everything, at scale, with simple API calls. Feed it a name and company, and get back a full profile: enriched emails, phone numbers, LinkedIn URLs, and company data. It's the single, powerful endpoint to make your existing lead lists instantly more valuable and actionable.

SoloTools

AI-Powered Proposal Generation

This isn't just a dumb template filler. You give it the basic project ingredients, and the AI writes the whole meal - a compelling executive summary, detailed scope breakdowns, professional pricing tables, and persuasive terms, all tailored to your specific gig. It does the heavy lifting so you don't have to sound like a robot copying from your last proposal. It generates the full, polished doc in about 12 seconds, turning your few words into client-ready gold.

Smart AI Editing & Refinement

Stuck on a section? No sweat. SoloTools lets you tweak the AI's writing on the fly with simple commands. Just tell it to "Make this more persuasive," "Make it shorter," "Add more detail," or "Rewrite in a formal tone" for any specific part of the proposal. It's like having an editor in your pocket that instantly refines your text to hit the right note, saving you from the frustration of rewording things yourself.

Built-in E-Signatures & Tracking

Go from "sent" to "signed" without the annoying chase. Send proposals directly via email from the platform and then track when the client opens it (you get a notification!). They can sign it right there with a canvas e-signature, accepting or even declining with a reason. You can also set expiry dates to create urgency and automatic follow-up reminders, so you never have to send that awkward "just checking in" email again.

Proposal Analytics & Insights

Wanna know what's working? The analytics dashboard shows you your entire conversion funnel - how many proposals you sent, were viewed, and were accepted or declined. See your win rate and average close time. It helps you spot where you're losing deals so you can tweak your approach. Plus, with real-time view notifications, you know the exact moment a client opens your doc, so you can follow up at the perfect time.

Frequently Asked Questions

BlitzAPI FAQ

What makes BlitzAPI different from other data providers?

Most data vendors sell you bulk, unverified lists full of outdated info. BlitzAPI flips the script. We're API-first, built to integrate into your workflow. We prioritize quality and deliverability, so you only pay for verified, accurate results (not noise). Plus, our catch-all validation is next-level.

How does the "pay for verified results" model work?

Simple. You get credits. You only use a credit when we successfully return a verified piece of data you request (like a validated email or phone). If we can't find it or verify it, you don't get charged. No more wasting money on empty searches or bad data. It's fair and scalable.

Is it easy to integrate BlitzAPI into our existing tech stack?

Absolutely. We're built by devs for modern GTM stacks. Our APIs are clean, well-documented, and designed for easy integration into CRMs (like Salesforce), marketing automation tools, data warehouses, and custom apps. You shouldn't need an engineering PhD to get it running.

What kind of data coverage and accuracy do you have?

We're packing serious heat: over 360 million verified B2B contacts and 60 million enriched company profiles. Our email deliverability rate is over 98%, thanks to real-time validation tech that even tackles catch-all domains. We focus on major markets to keep our data fresh and reliable.

SoloTools FAQ

Is there really a free plan?

Absolutely, and it's legit. The free plan lets you create and send 3 full proposals every single month, no credit card required to start. You get access to the core AI generator, editable proposals, and shareable links. It's the perfect way to test if SoloTools vibes with your workflow before deciding to upgrade for more power.

How does the AI know what to write?

The AI is trained on tons of successful business proposals. You give it the key details: client name, project type, budget, and your notes. It uses that context to structure a professional proposal tailored to your industry (it has starter templates for web design, SEO, marketing, etc.) and writes compelling, relevant content for each section, pulling from proven formats.

Can I edit the proposals the AI creates?

100% yes! You have full control. Think of the AI as your first draft superstar. Every section is fully editable. You can type directly, or use the AI editing commands to refine text on the spot ("make more persuasive," etc.). You can also customize pricing, timelines, and terms before sending or downloading the final version as a PDF or Word doc.

Are the e-signatures legally binding?

Yes, the e-signatures collected through SoloTools are legally binding. The platform provides a clear audit trail showing the client's drawn signature, the date, time, and IP address associated with the acceptance. This is standard for modern digital signature processes and holds up in business agreements, just like other dedicated e-signature tools.
