What is Pretus?

Pretus is an AI-powered investment banking interview prep platform at heypretus.com. Its core product is the AI mock interview: you run a full simulated interview tailored to a specific firm, group, office, and stage of the recruiting process, and the platform gives instant feedback, tracks your progress over time, and surfaces the areas you need to work on. Pretus backs this with a question bank of over 2,000 real interview questions drawn from every top IB firm. According to its own marketing, you can sign up for a free account without entering payment details. The company was founded by Cosmo Guion and Lucas Vogel, is based in Redwood City, California, and is at the pre-seed stage, so it's an early but actively growing tool.

Where Pretus wins

Pretus is strong where it concentrates: firm-specific mock interviews and a free entry point. The mock interview is tailored to a specific firm, group, office, and recruiting stage, which is exactly the granularity you want in the two weeks before a superday. If you're interviewing with a particular bank's coverage group, a mock that's calibrated to that context is more useful than a generic one. For more on what that final stage looks like, see the investment banking superday guide.

The free account also lowers the barrier to trying it. You can sign up without a credit card, run a mock, and see the feedback loop before paying anything, which matters when you're a student weighing several tools. And with 2,000-plus real questions from top firms, the bank is deep enough that you won't run dry mid-recruiting. Pretus also leans into content and community through its newsletter and social channels, so it's visible where candidates already spend time.

Where IB Offer is stronger

IB Offer is built for repetition with feedback, which is where most candidates actually lose points. The mock interview tests whether you have internalized the technicals; the drills are how you internalize them in the first place. IB Offer ships AI-graded technical drills across accounting, valuation, DCF, LBO, and M&A: you answer, the AI scores it and tells you what was missing, and you rerun the concept until it is automatic. A mock-first tool tests the muscle; a drill-first tool builds it. If you want a sense of the raw material, the 400 questions investment banking guide shows how much surface area there is to cover.

IB Offer adds three things Pretus does not advertise: Ask IB follow-up explanations, unlimited free Mental Math, and per-topic weakness tracking. If your DCF answers are shaky but your accounting is solid, the platform points you back to the right drills. The question bank is also filterable by firm, group, and round, so you can narrow practice to your exact recruiting target. For the full scope of what gets tested, see the investment banking technical interview questions guide. IB Offer is priced at 19 dollars per month, 39 dollars per quarter, or 99 dollars per year.

Who should use which?

Choose Pretus if your main need is firm-specific mock interviews and you want a free way to start. If you have superdays lined up with particular banks and you want to rehearse the full interview in context, Pretus's tailored mocks and deep question bank are a good fit, and the free account means you can test it at zero cost.

Choose IB Offer if you want to drill technicals to automaticity, get follow-up explanations, and see exactly which topics are dragging you down. If you are earlier in prep or know your weak spots are in accounting, valuation, DCF, LBO, or M&A, graded drilling at a flat low price gets you more reps per dollar.

You can also use both: IB Offer for daily technical drilling and weakness tracking through the bulk of your prep, and Pretus's free mocks for firm-specific dress rehearsals right before each superday. They solve adjacent problems and stack cleanly.

Verdict

Pretus is a solid, focused AI mock-interview tool with a genuinely useful free tier and a deep, firm-tagged question bank. If a tailored mock interview is the one thing you want, it delivers that well. But mocks test what you already know, and most candidates fail on technicals they never drilled enough. IB Offer covers the learning loop with AI-graded drills, Ask IB explanations, unlimited Mental Math, and weakness tracking, all at a flat low monthly price. For most candidates, IB Offer is the stronger daily platform, with Pretus's free mocks as an optional final-week supplement.

Frequently Asked Questions

Is Pretus worth it?

Pretus is worth trying because its free account does not ask for payment details, so the cost of evaluating it is zero. Its AI mock interviews are tailored to specific firms, groups, offices, and recruiting stages, and the 2,000-plus question bank is deep. It is most worth it if firm-specific mock practice is your main gap. If your weakness is the underlying technicals, a drill-first platform like IB Offer will move the needle more per hour.

What is the best Pretus alternative?

IB Offer is the closest AI-native alternative to Pretus for technical practice. IB Offer adds AI-graded drills across accounting, valuation, DCF, LBO, and M&A, Ask IB, unlimited Mental Math, and per-topic weakness tracking at 19 dollars per month (less on the quarterly or annual plan). The simplest test is to create both free accounts and see which practice loop fits how you prep.

Does Pretus have a free tier?

Yes. According to Pretus's marketing, you can sign up for a free account without entering payment details and run mock interviews to see the feedback loop before paying. Specific paid tiers and prices are not listed publicly on the site, so check heypretus.com for current details. IB Offer also has a no-card free tier with 5 graded reps a day during the first 3 days of graded practice, 5 Ask IB messages a day free forever, and unlimited Mental Math. Its paid plans cost 19 dollars per month, 39 dollars per quarter, or 99 dollars per year.

Can AI mock interviews replace a real coach?

AI mock interviews cover a lot of what a coach does: structured feedback on your answers, unlimited reps, and progress tracking, all on demand and at a fraction of the cost. What they can't fully replace is a human's read on soft skills, networking strategy, and bank-specific culture. The strongest approach is AI for daily reps and the occasional human conversation for calibration.

Is Pretus or IB Offer better for last-minute prep?

For last-minute, firm-specific dress rehearsals, Pretus's tailored mocks and free account are convenient. For last-minute technical cramming, IB Offer's graded drills and weakness tracking let you hammer your weakest topics fast. Many candidates use IB Offer to drill the technicals and a free Pretus mock to rehearse the full interview the night before.
