Questions & Answers

As answered by people managing Calendly and Superthread.

What's the story behind your product?

Superthread's answer:

  • The Problem: David Hasovic, an experienced engineer with a background in creating high-performance software and game engines, grew frustrated with the inefficiency of tools like Jira and Confluence. He found that most project management platforms were technically complex, had poor performance, and forced teams to switch between multiple applications to manage tasks, documents, and discussions.

  • The Vision: He set out to build a new platform with the same standards of speed, resilience, and design polish found in high-performance games. The core idea was to create a "blazing-fast" tool that would bring tasks, documentation, and meetings together in a single, well-designed application.

  • The Journey: The journey was not simple. David described it as a "David vs. Goliath" story, going up against giants in the industry. The technical challenge of building a collaborative tool with both a task tracker and a rich text editor was immense, and the initial prototype code had to be completely scrapped to achieve the desired performance goals.

  • The Philosophy: Superthread's philosophy is rooted in "relentless attention to detail, engineering quality, and speed of execution." The team's goal is to ship fast and obsess over the user experience, ensuring the product is reliable whether a team has 10 tasks or 10 million. They focus on delivering a high-quality product without relying on marketing hype or "vapourware."

Which are the primary technologies used for building your product?

Superthread's answer:

  • Backend: The backend is built primarily with Go (Golang). This choice emphasizes the company's focus on high performance, concurrency, and reliability, which are key strengths of the Go language.

  • Frontend: The frontend is built using Vue.js, a popular JavaScript framework known for its simplicity and performance. The team has also been working on migrating from Vue 2 to Vue 3, indicating a commitment to modernizing their codebase.

  • Database: Superthread utilizes DynamoDB, a NoSQL database service from AWS. This choice is often made for its scalability and performance at a large scale, which aligns with Superthread's goal of handling millions of records without a loss of speed.

  • Other Technologies: The platform also incorporates TypeScript for adding static typing to the frontend, AWS for its cloud infrastructure, and WebSockets for real-time data communication, which is crucial for collaborative features.

Who are some of the biggest customers of your product?

Superthread's answer:

  • Acceler8 Talent: A technical recruitment company that used Superthread to unify global collaboration and reduce candidate review time by 30%.

  • Videra Health: An AI-powered health tech company that consolidated its scattered work from multiple tools (Monday, Shortcut, Notion) into Superthread to streamline operations.

  • Inblick: An AI data analytics platform that uses Superthread to consolidate both its engineering and non-engineering workflows to avoid losing context between different tools.

  • Medialab: A UK-based independent media agency that needed a solution to spread knowledge across its rapidly expanding business, switching from tools like Jira and Confluence.

  • AMD: Advanced Micro Devices (AMD) is a global semiconductor company known for designing and manufacturing microprocessors, graphics processing units (GPUs), and other related technologies.

  • lastminute.com: lastminute.com is the European Travel Tech leader in Dynamic Holiday Packages, giving holidaymakers access to millions of combinations of travel solutions in real-time.

  • IKEA: IKEA is a global home furnishing brand known for its modern, functional, and affordable furniture and home accessories, often sold in flat-pack form for customer assembly.

  • Grabyo: Grabyo is a cloud-based video platform focused on live production, clipping, and editing for broadcasters, publishers, and media organizations.

  • mercado libre: Mercado Libre is a leading e-commerce and online payments platform in Latin America.

  • AIRBUS: Airbus is a leading European aerospace corporation specializing in the design, manufacturing, and maintenance of commercial aircraft, as well as defense and space systems and helicopters.

Why should a person choose your product over its competitors?

Superthread's answer:

  • All-in-One Solution: Superthread is designed to replace multiple applications by integrating project management, documentation, and meetings into a single, cohesive platform. This eliminates the need for constant context switching between tools like Jira, Notion, and Slack.

  • AI-Powered Meeting Notes: A key differentiator is the built-in AI functionality that automatically transcribes meetings from platforms like Zoom and Google Meet. It then uses this information to suggest tasks, highlight key decisions, and update project-related documents, streamlining the workflow from discussion to action.

  • Speed and User Experience: The platform is engineered for high performance, with a clean, intuitive, and "blazing-fast" interface. Users frequently praise its ease of use and responsive design, which reduces friction and makes project management more enjoyable, even for non-technical team members.

  • Focused on "Builders": Superthread is specifically targeted at "builder" teams, such as software and product developers. It offers features and a workflow that cater to the needs of these teams, providing a more streamlined and relevant experience than more general-purpose or enterprise-focused tools.

  • Flexible and Customizable: While designed for speed, Superthread still offers a good degree of flexibility. Users can create custom views, define their own task statuses, and use tags to organize work in a way that fits their specific team's workflow.

What makes your product unique?

Superthread's answer:

  • Integrated Tasks, Docs, and Meetings: Unlike many competitors that require separate tools for project management (Jira), documentation (Confluence/Notion), and meeting notes, Superthread combines all three. This prevents "tool sprawl" and the need for constant context switching.

  • AI-Powered Meeting Notes: A standout feature is its AI Notes capability. The platform can transcribe meetings, automatically compare the discussion to existing work, and then suggest new tasks and action items, which can be reviewed and assigned with minimal effort.

  • Focus on Speed and Performance: The company emphasizes that its platform is "blazing-fast," a deliberate design choice intended to differentiate it from larger, more complex tools that can sometimes be slow or cumbersome. This focus on performance is a key part of its value proposition.

  • Built for "Builders": Superthread positions itself as a tool designed by and for builders, such as software and product teams. It aims to provide a fast, efficient, and well-designed experience that caters specifically to the needs of technical users.

How would you describe the primary audience of your product?

Superthread's answer:

  • Engineering and Product Teams: Superthread is designed to meet the specific needs of these teams by combining task management with documentation in a single platform, streamlining their workflows.

  • Teams Consolidating Tools: Companies that are tired of using separate applications for project management (e.g., Jira), documentation (e.g., Notion), and team communication (e.g., Slack) represent a core target market.

  • Remote and Hybrid Teams: The centralized nature of the platform makes it well-suited for distributed teams that need a single source of truth for all their work and discussions.

  • Startups: With a pricing model that includes a free tier for unlimited users and a startup program offering significant discounts, Superthread is an attractive option for new, growing companies seeking an efficient, scalable solution.

Acuity Scheduling alternatives for businesses outgrowing it
Calendly is the meeting-scheduling default โ€” connect calendars, share a link, and let people book time, with round-robin and team routing on paid tiers. If your "Acuity problem" is really just meetings and your business doesn't hinge on deposits, packages, or a service storefront, Calendly is cleaner and more focused than Acuity for that job.

The Best 24 Appointment Scheduling Apps and Booking Software
I have frequently used Calendly in the past, primarily for scheduling job interviews. What I appreciate about Calendly is that the free version still allows you to connect one calendar, book unlimited meetings, create a custom Calendly link, and send out automatic email notifications and reminders to invitees who book with you.
neetoCal, a calendly alternative, is a commodity and is priced accordingly
neetoCal is not the first company to compete with Calendly. We are not even the second company to compete with Calendly. We are probably the 30th player in this crowded space. With so many players in the market, scheduling software seems like a commodity.

Calendly is only $12/month for their professional plan which saves you money if you even schedule only one meeting a month with it.
The Best Alternatives to Doodle That You Should Check Out
Some may remember the Zoom.ai application. This app has been rebranded as CalendarHero, which resembles Calendly. You can suggest different meetings at different times and then share a link with invitees. Invitees can then indicate their preferred meeting time.
