As answered by people managing CheckIO and Tability.
Tability's answer:
Tability was founded by ex-Atlassians who saw firsthand how difficult it was to keep teams aligned on strategy. Too often, OKRs got lost in slides, docs, and spreadsheets—making them ineffective. The idea behind Tability was simple: create a modern platform that hleps you focus and work on the right things. Tability keeps strategy visible, keeps teams aligned, and helps teams focus on impact rather than busywork.
Tability is trusted platform used by hundreds of startups and enterprises worldwide.
Tability's answer:
Tability is designed to take the pain out of OKRs and goal tracking. Unlike heavy strategy tools, it’s lightweight, AI-native, and simple enough for teams to actually adopt. It combines the clarity of OKR platforms with the usability of a task app—helping teams stay aligned on priorities without adding another layer of admin work. Features like Tabby AI (your built-in OKR agent) make progress updates, reporting, and insights automatic, so teams can focus on outcomes instead of status reporting.
Tability's answer:
Most OKR and strategy tools feel complex, enterprise-only, and slow to roll out.
Tability stands out because it’s: • Fast to adopt: Teams can set up and start tracking OKRs in minutes. • Intuitive and good for the team: Designed with the end-user in mind so it's useful for your team as much as it is for your leadership team. • AI-native: Tabby AI automates check-ins, reporting, and insights—something most competitors don’t offer. • Affordable & flexible: Built for startups and growing companies as well as larger organisations. • Modern & clean UI: Designed with simplicity in mind, so teams actually use it.
Tability's answer:
Tability primarily serves CEOs, founders, and Chiefs of Staff who need to align their teams around strategic goals without micromanaging. It’s also popular with product, operations, and strategy leaders at startups and mid-sized companies who want a lightweight way to keep OKRs on track. The common theme is leaders who want better alignment, less status chasing, and more focus on outcomes.
