Zintlr features and specs

  • Lookup
    Find Global Decision-Makers- Lookup is your go-to tool for extracting accurate contact details and professional backgrounds from LinkedIn’s vast network and global company databases. It provides verified phone numbers, professional email addresses, career histories, educational backgrounds, and detailed company insights such as industry, size, and headquarters. Sales teams rely on Lookup to rapidly build lead lists, pinpoint decision-makers, and enrich CRM data with up-to-date contact information. Using Lookup is simple: enter a company name or keywords, refine results with filters for people or companies, and layer multiple filters to define your Ideal Customer Profile. You can save filters, revisit past searches, unlock contact details individually or in bulk, add prospects to lists, and export them to CSV. Profiles can be explored in depth, and results can be streamlined using skip, clear filters, or bulk action features. Even in cases of zero results, Zintlr records the query to continuously imp rove search accuracy.
  • Indian Data Suite (IDS)
    Premium B2B Contacts in India- The Indian Data Suite provides exclusive access to Indian companies and executives with unparalleled detail. It includes verified mobile numbers and emails of C-suite leaders, company financials, CIN and GSTIN numbers, and registration data. Sales teams use IDS to precisely target Indian enterprises, access executives directly, and validate companies with financial and legal credibility. The workflow mirrors Lookup but is tailored to India. Users can apply filters such as state, city, company type, paid-up capital, or director identification numbers to refine searches. Results can be saved, revisited, and exported, with full support for unlocking, bulk unlocking, list creation, and profile exploration. IDS also tracks zero-result pages, helping refine strategies.
  • Personality Intel
    Sell the Way Your Prospects Think- Personality Intel analyzes publicly available LinkedIn activity and communication patterns to reveal behavioral traits and communication styles. It highlights whether a prospect is analytical, assertive, collaborative, or empathetic, and recommends outreach styles that resonate—formal or casual, data-driven or emotional. The tool also suggests ideal follow-up strategies to help build rapport faster. Sales teams use Personality Intel to adjust pitch tonality, avoid ineffective messaging, and strengthen connections from the very first conversation. To use it, simply enter a LinkedIn profile URL, generate the personality report, and apply the insights in your email, InMail, or call strategies. The Chrome Extension further enhances this by delivering instant personality analysis directly on LinkedIn profiles.
  • Domain Search
    Extract Website-Based Contacts- Domain Search allows you to extract publicly available contacts, technologies, and executive data directly from a company’s website. It scrapes pages such as “About Us,” or “Contact” to uncover email addresses and phone numbers while identifying the company’s tech stack and executive listings. This is especially powerful for targeting companies without a strong LinkedIn presence. Sales teams use Domain Search to discover hidden contacts, personalize pitches with tech insights, and generate new leads directly from websites. To use it, simply enter the domain, review extracted results, and add them to lists or export unlocked contacts
  • Local Business Search
    Hyper-Targeted Lead Generation- Local Business Search is designed for discovering businesses by location and category, making it ideal for field sales and localized outreach. It provides full listings with business names, addresses, phone numbers, websites, reviews, and descriptions. Sales teams depends on it to generate location-specific leads, expand territory coverage, and cross-reference data for higher accuracy. Using the tool is straightforward: enter the type of business and location, initiate the search, review the results, and export them into Excel or CRM systems for immediate use in campaigns.
  • AI Search Bar
    One of the most anticipated enhancements is the Intelligent Single Search Bar with AI Filters, which unifies Lookup and IDS into a single, smart command center. Instead of toggling between tools or manually configuring filters, you’ll simply type in a natural language query, such as “Find SaaS sales directors in Bangalore who use Salesforce,” and our AI will instantly translate it into precise filters. This eliminates guesswork, speeds up searches, and unleashes the full potential of Zintlr’s database in seconds
  • Zintlr Chrome Extension
    Instant Data on LinkedIn & Websites- The Zintlr Chrome Extension brings prospecting power directly into your browser. Once installed from the Chrome Web Store, you can log in and start uncovering verified contacts instantly. On LinkedIn profiles and company pages, it provides one-click access to verified emails, phone numbers, and insights. On Indian financial and legal portals like Zaubacorp or Tofler, it shows C-suite contacts, revenue, and registration data. While browsing LinkedIn, it also delivers Personality Intel—instant reports and icebreakers to help you personalize outreach. When visiting company websites, the extension extracts publicly available contacts and highlights key executives with a single click.
  • Bulk Unlock Notifications
    We’re also optimizing workflows with Smarter Bulk Unlock Notifications, so you’ll no longer wait in the dark to know when contacts are verified. Instead, you’ll receive instant alerts the moment your requested list is ready, empowering you to launch outreach campaigns without delay. Alongside this, our Faster Refund Pipeline ensures that any credits used for bounced or inaccurate contacts are returned swiftly, reinforcing confidence in both our platform and the quality of your investment.
  • Lists
    Organize, Manage, and Collaborate on Your Leads- Lists are central to managing contacts discovered through Zintlr. They allow you to group, categorize, and collaborate on prospects efficiently. Zintlr maintains Lookup lists, IDS lists, and a default domain search list, along with auto-generated lists of all unlocked contacts. Lists can be private, for personal prospecting, or public, for team-wide collaboration. Sales teams benefit from structured data organization, alignment with campaigns, and the ability to share leads seamlessly. Within lists, you can edit, delete, or adjust privacy settings, as well as unlock contacts individually or in bulk. Exporting unlocked contacts to CRM, importing contacts from Excel, or moving them across lists ensures smooth workflows. Zintlr also tracks how users unlock contacts whether individually or in bulk—to optimize productivity.
  • CRM Enrichment
    Push to CRM with Salesforce, HubSpot, and Zoho allows users to seamlessly send or sync enriched lead and contact data directly into their CRM systems. With Manual Enrichment, users can review and update records before pushing them, ensuring data accuracy and relevance. This process helps maintain clean, complete, and up-to-date CRM databases for better sales and marketing performance.
  • API Integration
    Unleash unprecedented automation and data synchronization. Empower your developers to build custom solutions, enhance your internal tools, or even embed Zintlr's data into your own B2B offerings. The power of Zintlr, tailored to your exact specifications.
  • AI Insights
    AI Insights offers real-time trends and insights about a person or company, helping sales reps understand interests, activities, and market movements. This enables more personalized outreach and smarter prospecting decisions.
  • Advance Search Filters
    30+ Filter- We provide Advanced Search Filters with over 30+ filtering options to help you find the right prospects quickly and accurately. These filters allow you to narrow down searches based on criteria like industry, location, company size, job title, revenue, and more — ensuring highly targeted and relevant results for your sales and marketing efforts.

    Zintlr offers various account types, each tailored to different prospecting needs. Understanding your account's feature and usage limits is key to maximizing your Zintlr experience. Your limits are automatically managed and tracked within the platform.

startbase.dev features and specs

  • Faster project setup
    Startbase.dev appears designed to help developers and founders quickly scaffold new projects with pre-built templates and boilerplate code, saving significant time compared to starting from scratch.
  • Focus on startups/MVPs
    The platform seems tailored toward entrepreneurs and indie developers who want to launch minimum viable products quickly, which can be valuable for validating ideas without heavy upfront investment.
  • Modern tech stack
    Such starter kits typically integrate current, popular frameworks and tools (e.g., Next.js, Tailwind, authentication, payments), reducing the need to research and configure these integrations manually.
  • Reduced boilerplate maintenance
    By using a pre-built base, developers can avoid reinventing common features like user authentication, billing, and dashboards, letting them focus on unique business logic instead.
  • Potential cost savings
    Compared to hiring a development team to build core infrastructure from scratch, using a starter template service can be more affordable for solo founders or small teams with limited budgets.

Possible disadvantages of startbase.dev

  • Limited customization flexibility
    Pre-built starter kits and boilerplates often come with opinionated architecture and design choices that can be difficult or time-consuming to modify for highly specific or unconventional use cases.
  • Vendor/template lock-in risk
    Relying on a specific boilerplate structure may create dependencies on certain libraries, patterns, or update cycles that could complicate long-term maintenance if the base template becomes outdated.
  • Learning curve for the specific stack
    If the chosen tech stack differs from what a developer is familiar with, there may still be a learning curve to understand and effectively customize the starter codebase.
  • Uncertain long-term support
    As a smaller or newer platform, there may be concerns about the longevity of updates, community support, and documentation compared to more established open-source alternatives.
  • Pricing transparency concerns
    Depending on the pricing model, users may find costs less transparent or harder to justify compared to free, open-source boilerplates available elsewhere in the developer community.
