Starnus is an AI-powered outbound sales automation platform built for founders, startups, and B2B sales teams who want to automate prospecting and outreach without juggling multiple expensive tools. With Starnus, you can define your ideal customer profile (ICP) using simple natural language prompts, discover lookalike prospects from millions of verified business records, enrich leads with business and contact data including emails, phone numbers, company size, industry, and revenue, generate personalized multi-channel outreach across email and LinkedIn, automate follow-up sequences based on engagement signals, and track opens, replies, and conversions from a single dashboard. Starnus replaces the need for separate tools for prospecting, data enrichment, email sequencing, and campaign analytics. Instead of paying for Apollo + Clay + Instantly + a data provider, Starnus combines everything into one AI-driven workflow. Built for solo founders doing outbound for the first time, small B2B teams scaling pipeline without adding headcount, and agencies managing outreach for multiple clients. Starnus integrates with HubSpot, Gmail, Google Sheets, and Slack. Start with a free 14-day trial โ€” no credit card required.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.
