Kestral logo

Kestral

We automate your entire product development lifecycle.

Kestral makes it clear what your customers want most, prioritizes those tasks for highest leverage, and closes the loop with those customers. We (Brian and Bernard) have been close friends since university, and most recently worked together at Asana, leading AI and Authorization efforts. There we realized AI can completely disrupt the $50B Work Management Market, but it required a fresh start. What work we even choose to manage in the first place is critical, and the most important insights from customers are silo-ed in sales/CS while R&D gives their best shot at roadmaps meant to deliver impact. Significant requests sit in a backlog, duplicate asks flood the system, months wasted on "strategic investments". We want to bridge this gap. This message is resonating with heads of sales, heads of product, CEOs, as well as individuals, all trying to make sure the most important things get done, with less wasted effort and more revenue/retention. Kestral works by automatically take in customer data like sales call transcripts & feature request messages and a team of agents: 1. analyze them for actionable takeaways, deal blockers, and nice to haves 2. consolidate them and manage all the asks with citations 3. prioritize them by impact and frequency to cut through the noise so you can see the biggest opportunities clearly 4. connect them to your existing strategic roadmap so when the work gets done, we can automatically follow back up with your customers and win them over This is just step one of our mission to revolutionize how work gets done -- starting with what we choose to work on, and hope you follow us along for the ride!

When approved, Keylika’s proprietary transdermal iron will be the world's first prescription iron patch. Iron deficiency is a hugely understated problem affecting about 1.6 billion people worldwide and more than 30 million in the US alone, translating to a $17B US market.
