Quick answers

Did Ildar Shar co-found StackAdapt?

Yes. BetaKit (2014-01-07), writing when the company still traded as CollectiveRoll and StackAdapt was its product in private beta, reported that "Cofounders Vitaly Pecherskiy, Ildar Shar and Yang Han expect a full release in March." StackAdapt's own about page, read 2026-10-17, says the three founders "launched" the platform "in 2014 in Toronto." ExchangeWire (2024-01-11) calls him "StackAdapt co-founder and outgoing CEO Ildar Shar."

What did Ildar Shar do before StackAdapt?

He worked at WPP. The Globe and Mail (2025-02-04) reports that Pecherskiy "and original CEO Ildar Shar, both Russian immigrants, came up with the idea while working for advertising multinational WPP PLC in Toronto." StackAdapt's author page, read 2026-10-17, says he "served as CEO from 2013 to 2023." No fetched page states what he did before WPP or where he studied.

Has Ildar Shar spoken at TechTO?

No. StackAdapt's one TechTO stage appearance is a Demo of the Month at MarketingTO in October 2018, given by an employee the archive identifies only as Eli. Tishan Mills, now SVP, Platform at StackAdapt, spoke at TechTO on 2017-09-25, but for his earlier company QuickTapSurvey.

Where is Ildar Shar based, and what is his role today?

StackAdapt's author page for him, read 2026-10-17 and last modified 2026-03-17, lists him as "Co-founder, Board Member" and says "He continues to provide strategic support on StackAdapt's Board of Directors." ExchangeWire (2024-01-11) reported the same board role when Vitaly Pecherskiy became CEO. No fetched page states where Shar lives; the Globe and Mail places him at WPP in Toronto before the company started, so no city is recorded.
