The Next Breakout Might Be in Your Pocket
Everyone’s hunting for the next Unicorn.
The type of “category disruptor” that grows fast and turns early believers into big winners.
59,000+ investors think that Mode Mobile could be one of those rare finds.
Americans spend 4 ½ hours on their phones daily, and Mode Mobile is monetizing that screentime. With $1B+ earned by over 490M customers and 32,481% revenue growth, Mode’s EarnPhone is turning smartphones into income generating assets.
Their previous raises sold out, and the company is now offering pre-IPO shares at $0.52/share with up to 20% bonus, exclusive to early investors.
Being early is everything, and this window is still open.
*Please read the offering circular and related risks at invest.modemobile.com.
Mode Mobile recently received their ticker reservation with Nasdaq ($MODE), indicating an intent to IPO in the next 24 months. An intent to IPO is no guarantee that an actual IPO will occur.
The Deloitte rankings are based on submitted applications and public company database research, with winners selected based on their fiscal-year revenue growth percentage over a three-year period.

Final Table
Company | 2019 | 2020 | 2021 | 2022 | 2023 |
|---|---|---|---|---|---|
A | 1210 | 8178 | 4523 | (1000 to 5000) / 6723 | 8972 / (1000 to 5000) |
B | 2435 | 5000 | 5245 | 3425 | 9020 |
C | 3452 | 5000 | 5688 | 3908 | 5129 |

Set 1
The data in one of the two entries for A (years 2022 and 2023) is incorrect. The data in one of the two entries for B (years 2019 and 2020) is incorrect. The data in one of the two entries for C (years 2019 and 2020) is incorrect.
Based on conditions (b) and (c), the sales of each of B and C in the year 2020 was ₹5000 crores.
For company A, if the entry 6723 is correct, then the entry 8972 has to be rectified (to less than or equal to ₹5000 crores). However, if the entry 8972 is correct, then the entry 6723 has to be rectified to S, such that S is less than or equal to ₹5000 crores. This implies sales for A in either 2022 or 2023 (but not both) is at most ₹5000 crores.
Question 1
Total sales of B = 25125
Total minimum sales of A = 1210 + 8178 + 4523 + 6723 + 1000 = 21634
Total maximum sales of A = 1210 + 8178 + 4523 + 5000 + 8972 = 27883
Maximum possible difference = 25125 − 21634 = 3491
Choice (A)
Question 2
D in 2020 = 3452 / 28153 = 12.26%
D in 2021 = 7654 / 24524 = 31.21%
Difference ≈ 19 percentage points
Choice (D)
Question 3
The total sales of C across the five years are 23177.
Answer: 23177
Question 4
Except A, for all other companies, the total sales can be determined uniquely.
Answer: 4
