How Legacy works in Build a Phone Empire: selling your company, permanent bonuses and the best timing to rebirth.
Build a Phone Empire Legacy: Rebirth Guide
Legacy is Build a Phone Empire's rebirth system: you sell the company you spent years building and walk away with permanent account bonuses that make the next company stronger. The community documentation describes it as "a permanent account perk obtained by selling your established company" — the tycoon endgame that turns one good run into a compounding series of them.
This page covers the mechanic as it is documented, the timing logic the community has converged on, and the honest gaps — because Legacy is the least officially documented system in a game that documents very little.

What Legacy Actually Does
The verified shape, per the fan-maintained trackers that follow the game:
- Selling the company is the trigger — a mature company is exchanged, and the run ends.
- Permanent bonuses persist on your account afterward. The exact bonus stack (multipliers, starting capital, unlocked conveniences) is community-documented rather than officially published; the wikis agree on the permanence, less so on the specifics.
- A new run begins with those bonuses active — the same 2007 garage, a stronger operator.
What Legacy does not touch, per the community documentation: research unlocks persist (the tech tree is the long-game asset), and gamepass perks attach to the player rather than the company. The rebirth resets the company, not the player.
Official source: Build a Phone Empire on Roblox — the developer's page hosts the live game where the Legacy flow runs; the system's details above are community-documented because the developer publishes no economy documentation at all.
Legacy's persistence rules here follow the community trackers — GameStratWiki and BloxRant — whose rebirth notes align with the research-persistence claims.
Why Sell a Thriving Company
The rebirth logic confuses players until the compounding is visible. A mature company earns well but linearly; a Legacy bonus applies to every future company from minute one. The community's framing is the honest one: Legacy trades a strong present for a permanently stronger future, and the exchange is worth it once the present is genuinely strong.
The visible math, in broad strokes:
- Run one: build the company, learn the systems, ship the tech tree's foundations, sell.
- Run two: the same loop plays faster — bonuses compress early grind, and the research you kept unlocked means better devices from earlier years.
- Run three onward: the garage era shortens toward a formality, and the game's real endgame becomes optimization across runs.
This is why the community treats Legacy as the answer to "what is there to do after the goals are done" — the goals board completes, the headquarters is built, and the rebirth converts that plateau into the next ramp.
The bonus you carry out scales with the company you built. A hasty sale from a mediocre company buys a weak multiplier and forfeits the mature-company income you were days from anyway. The community's consistent advice: complete the late goals, finish the tech branches you funded, and sell at a genuine plateau.
Timing: The Question Every Player Asks
Exact Legacy bonus values are not published, so timing advice has to be structural rather than numerical. Three signals say the company is ready:
- The goal board is complete or nearly so. The milestone rewards are free Cash that strengthens the sale — bank them first.
- Research spending has nowhere to go. If your RP income exceeds the branches you can fund, the company's growth engine is idling; that is rebirth pressure.
- Launches feel routine. When every year is a variation on a solved formula, the marginal value of another in-game year is lower than the permanent bonus from selling.
The counter-signals matter just as much: an incomplete tech branch you have already funded (the unlock outlives the company — finish it before selling), an upcoming developer update the community expects to add systems (three-to-four-day cadence means the wait is short), or a first run where you are still learning the systems. First-run players almost always sell early; the second run teaches you what the first one should have built.
The Pre-Sale Checklist
Because the sale is irreversible, the community's habit is a short checklist, and it is worth adopting:
- Finish funded research branches. Unlocks persist; half-funded ones do not carry the same value.
- Cash out the goal board. Milestone rewards are run-specific income.
- Ship the flagship you have been saving. One strong final launch with full marketing backs up the sale and the habit stack you take forward.
- Redeem live codes. RP and Cash from codes flow into the final company's value and the bonuses.
- Screenshot the office. The headquarters you built is about to become someone else's memory — the social layer of the game deserves the farewell shot.
What Carries Over (And What Does Not)
The persistence table, as the community documents it:
| Carries over | Resets with the company |
|---|---|
| Legacy bonuses | Cash and company assets |
| Research unlocks | The office you built |
| Gamepass perks | Hired staff (including friend avatars) |
| Codes redeemed (their rewards feed the run) | The goal board's completion state |
The table explains the game's whole endgame economy: everything you genuinely own — knowledge, unlocks, perks — survives the sale, and everything the company was is what you exchange for the bonuses. It is a clean design, and it is the reason experienced players talk about Legacy runs as the game's real structure rather than a postscript.
Legacy and the Update Cadence
The developer's three-to-four-day update rhythm interacts with rebirth timing in a way worth planning around. New systems added mid-run — a new device category, a fresh goal cluster, a rebirth-rule tweak — land their fullest value on a fresh company rather than a mature one, since a new run gets to build around them from the garage instead of retrofitting. Community history so far supports the pattern: each October update wave brought content that early-run players adopted faster than established ones.
The practical version: if the community is expecting a content wave and your company is near a plateau, the plateau is your sell window. Cash in the bonuses, let the update land, and open the next run with the new systems already part of the plan. It is the one timing call where waiting a few days measurably changes the next hundred in-game years.
FAQ
What is Legacy in Build a Phone Empire?
The rebirth system: you sell your established company and receive permanent account bonuses that strengthen every future run. The community documentation describes the perk as permanent and account-bound.
How do I trigger a Legacy reset?
By selling your company through the Legacy flow once the game considers it established. The in-game flow walks the sale; the community's advice is to complete goals and funded research first so the sale happens from strength.
Do I keep my research after a Legacy reset?
Yes — research unlocks persist across the sale, per the community documentation. The tech tree is the long-game asset, which is why RP spending is never wasted even right before a rebirth.
What is the best time to sell my company?
At a genuine plateau: goal board complete, funded tech branches finished, launches routine. Selling early from a weak company buys a weak multiplier — the bonuses scale with what you built.
Do gamepasses survive a Legacy reset?
The community documentation treats pass perks as player-attached rather than company-attached, so they persist. That is why the pre-sale window is the best time to buy one — the Robux does work across every future run.
