Frequently Asked Questions

Yes. You can browse the entire platform without an account: every feature, list, and library is visible. Creating a free account takes a minute and lets you actually train: play the Trading Game, the Mental Math and Sequences trainers, and Order Recall on easy difficulty, and answer the curated free questions across the question banks.

On the Quant track: the Trading Game, Mental Math, Sequences, and Order Recall on easy difficulty, 20 curated Trader Questions with full worked solutions, and the first two lessons of every Quant Education course.

On the Fundamental track: the three-statement modelling lab through the whole Revenue Modelling section, the first module of Tiers 1 and 2, and 10 curated Finance Technical Questions with model answers. The research library is browsable end to end; reading reports is a member feature.

No. Saved progress, session stats, question mastery, and model autosave are Membership features. Free accounts can play and answer, but nothing persists between sessions: members have continuity, free users have moments.

Deltashark is one product: Deltashark Membership. Three billing options: $39 every 4 weeks, $96 every 3 months, or $240 annually. Membership unlocks the full platform across both tracks and saves your progress everywhere.

Everything on the platform. The full Quant track: every game and trainer at every difficulty, the real assessment formats, the complete Trader Questions bank, and all eight Quant Education courses, with sessions, stats, and progress saved throughout.

The full Fundamental track: every education module across all four tiers, the four interactive modelling labs (three-statement modelling, DCF, comparable company analysis, and the equity pitch masterclass), the complete technicals bank with active-recall scheduling, and the career track. The full research library across equity, macro, and sector is included, with new reports on a regular cadence.

Plus the Community: a members-only feed for posting questions, sharing wins and interview experiences, and learning from peers on the same path. Bi-weekly one-hour support calls hosted by founder Burak M. Gunduz are included, with live questions, CV reviews, interview prep, networking, and whatever else comes with working to break into the industry.

Interview preparation for quant trading, market making, and prop firms. Mental Math and Sequences trainers built to the real assessment formats, Market Making Games played from both sides of the market, Cognitive Games covering the four paradigms of trading-firm cognitive batteries, a bank of Trader Questions across probability, expected value, statistics, option theory, reasoning, and brainteasers, and eight Quant Education courses covering the maths underneath it all.

Yes, deliberately. The Mental Math trainer includes the 80-questions-in-8-minutes format with negative marking, the Sequences trainer includes the 25-in-25 dedicated-section format, the Cognitive Games mirror the paradigms behind trading-firm cognitive batteries, and the Market Making Games are modelled on the games trading firms actually play in interviews.

Every question has one numerical answer, instant checking, a hint, and a full worked solution. Members can run timed practice sessions filtered by category and difficulty, bookmark questions, and track solved progress across the bank.

The Modelling Lab takes you through four core hedge fund models step by step inside the browser, on real company data. The three-statement model covers forecasting, linking, and circular references. The DCF lab walks through forecast period, terminal value, WACC build, and sensitivity tables. The comps lab covers peer selection, multiples, and clean-up adjustments. The equity pitch masterclass covers the hook, three thesis pillars, bear/base/bull valuation, and risks.

Yes. Every lab ships with a finished Excel file you can download and keep, so you have a working reference model alongside everything you build inside the browser.

The curriculum is written by professionals with direct hedge fund experience. It covers accounting fundamentals, valuation, modelling strategies, portfolio construction, risk management, sector deep-dives, and interview preparation. Every module is grounded in what is actually used on a professional desk, not in textbook abstractions.

We publish three categories of research. Equity reports cover single-name companies in depth, with thesis, supporting data, risk factors, and a clear conclusion. Macro reports cover rates, inflation, growth, and policy across the major economies. Sector reports cover competitive dynamics and unit economics across the industries that matter.

No. Reports are written by former hedge fund analysts and represent the views of their authors at the time of publication. They are intended for educational and informational purposes and should not be interpreted as personalised investment recommendations.

Every report is signed by a real author. Each author has a public Deltashark ID showing their bio, education, work history, and the rest of their published research. You can click through from any report to see the author profile.

No. Deltashark is an educational platform. We are not a broker, investment adviser, or financial institution, and we are not regulated by the FCA, the SEC, or any other financial regulatory body. We do not execute trades, manage client assets, or provide personalised investment advice.

Your Deltashark ID is a public profile at deltashark.io/p/yourname. It shows your bio, schools, target firms, work history, and every piece of equity research and financial model you have published. Add the link to your CV when applying to hedge funds, equity research, investment banking, or asset management roles. Hiring managers see exactly what you can do, not just what you studied.

Your Deltashark ID is private by default. You decide whether it is public, and you control what appears on it. You can switch visibility on or off at any time from your account settings.

Deltashark is an all-in-one platform for preparing for quant trading and equity hedge fund interviews. Two tracks under one roof: the Quant track trains the speed, probability, and market instincts that quant trading, market making, and prop firms test, and the Fundamental track builds the accounting, valuation, and modelling craft that equity hedge funds and asset managers hire for, alongside original research written by former hedge fund analysts.

Anyone working to break into quant trading or hedge funds: students preparing for assessments and interviews, career changers building the skills from scratch, and early-career analysts sharpening their craft. The free tier is built so you can try the real thing before paying anything.

Deltashark is based in London, United Kingdom. The platform is available globally.
