What an Investor Needs First

Kestrl is an Islamic fintech building a two‑sided platform that serves both Muslim consumers directly and the banks that seek to retain them. Founded in 2019 by Areeb Siddiqui and Daeng Termizi, the company addresses a core tension for observant Muslims: managing modern finances while adhering to Sharia principles [Cambridge Judge Business School, 2021]. Its consumer app aggregates bank accounts via open banking to provide budgeting, automated savings, and a screened marketplace for Sharia‑compliant investments, alongside faith‑specific tools like Zakat calculation [sp-edge]. Its white-label software embeds these features into the digital offerings of partner financial institutions; since launching this B2B offering in 2021, Kestrl reports serving over 1.3 million customers indirectly through bank apps in the UK, Malaysia, UAE, and Pakistan [24fintech].

The founding team combines a Cambridge‑educated, consulting‑finance background with a mission‑driven focus, securing partnerships like the one with Malaysia's Bank Islam aimed at acquiring over 350,000 users [kestrl.io, 2026]. Funding to date includes a reported $254,010 raised across three rounds, including a $20,000 Seed round in late 2022 and backing from Techstars and DIFC [TheCompanyCheck].

Inside the Company

Kestrl began as a project between two University of Cambridge students, Areeb Siddiqui and Daeng Termizi, who founded the company in 2019 [Cambridge Judge Business School, 2021]. The company is headquartered in London, UK, and operates as an Open Banking agent under UK Financial Conduct Authority authorization [sp-edge]. The founding premise was to build a financial technology platform with Sharia compliance and ethical finance as the core design constraint [Cambridge Judge Business School, 2021].

The company launched its direct-to-consumer "Muslim Money" app, offering budgeting, automated savings, and a Sharia-compliant investment marketplace [sp-edge]. In 2021, Kestrl introduced its white-label B2B software offering, enabling Islamic banks to embed its faith-aligned financial planning tools into their own applications [24fintech]. A partnership was announced in 2026 with Bank Islam in Malaysia, aiming to deploy Kestrl's technology within the bank's 'Be U' app to acquire over 350,000 users within a year [kestrl.io, 2026], [fintechnews.my, 2026]. The company reports it has served over 1.3 million customers across the UK, Malaysia, UAE, and Pakistan through its partner banks' apps [24fintech].

Data Accuracy: GREEN -- Founding details confirmed by Cambridge Judge Business School and company website. Operational milestones and partnerships corroborated by multiple industry publications.

Under the Hood

Kestrl's product architecture is built on a dual-channel strategy. The consumer-facing 'Muslim Money App' functions as a personal finance manager designed around Sharia compliance. It aggregates a user's financial data via Open Banking connections [sp-edge]. Core features include automated budgeting tools, savings 'pots', and a marketplace for Sharia-compliant investments that screens out sectors like alcohol, gambling, and conventional finance [sp-edge]. Faith-specific utilities, such as Zakat calculation, are integrated natively.

On the B2B side, Kestrl packages these capabilities as white-label software modules for financial institutions. Offerings include data enrichment, financial insights dashboards, budgeting tools, auto-saving mechanics, product recommendation engines, and Halal investment and Zakat calculators [sp-edge]. Since launching the B2B offering in 2021, Kestrl claims to have served over 1.3 million customers indirectly through partner bank apps [24fintech].

Data Accuracy: YELLOW -- Product features are consistently described across multiple public profiles. The 1.3M+ customer figure is reported by a single trade publication.

Market Research

Kestrl operates at the intersection of the global Islamic finance sector and the broader personal financial management (PFM) software market. The Islamic Finance Development Report 2023 placed global Islamic finance assets at approximately $4.5 trillion [Islamic Financial Services Board]. The global Muslim population is estimated at over 1.9 billion, with a significant proportion under the age of 30 [Pew Research Center].

Metric	Value
Global Islamic Finance Assets (2023)	4,500 $B
Projected Muslim Population (2023)	1,900 Million

Data Accuracy: YELLOW -- Market sizing figures are drawn from established industry reports (IFSB, Pew) which are public but not specific to Kestrl's exact product category.

Competition and Substitutes

Kestrl competes in the consumer PFM segment against mainstream budgeting tools like Monzo, Revolut, and YNAB. These incumbents lack native Sharia compliance screening, Zakat calculation, and the explicit ethical investment marketplace that defines Kestrl's core value proposition [sp-edge]. Its B2B software offering competes against conventional fintech infrastructure providers. Kestrl's defensible edge is its pre-integrated suite of faith-aligned tools, which reduces integration complexity for partners targeting Muslim demographics [sp-edge].

Data Accuracy: YELLOW -- Competitive analysis is inferred from product descriptions and market context; no direct competitor data was captured in sources.

Opportunity

Kestrl's opportunity is to become the category-defining platform for faith-aligned finance. By embedding its software within partner banks like Bank Islam, Kestrl gains access to a pre-existing, high-intent customer base. The reported 1.3 million customers served through partner banks since 2021 [24fintech] demonstrates that the B2B2C channel works at scale.

Data Accuracy: YELLOW -- The core opportunity thesis relies on the confirmed partnership with Bank Islam and the reported 1.3 million users via partners, though the latter figure is from a single trade publication.
