We build for large creators — the app or product your audience actually uses, and the DM & comment agent that converts the followers you already have. Two things: the scalable asset you own, and the machine that sells it in your voice. Engineered from scratch, source-owned by you on day one.
// The part nobody runs the numbers on
A large following is the most expensive thing to build and the most wasted once you have it. The audience is already there. The asset isn’t. Here’s the gap, in numbers.
1,000s
buyer-intent comments and DMs under a single viral post — almost none answered, because no human can.
<1%
of the average creator’s audience is ever offered something the creator actually owns.
$0
of brand-deal and ad income survives the month you stop posting. An owned product doesn’t care.
Run it yourself. 200,000 followers · 1.5% ever see an offer · 2% convert a $40 product = ~$2,400 a month — from an audience you already paid to build. An app compounds it. The agent captures it. Illustrative; your numbers will differ — we’ll model them on the call.
// Offering 01 — Custom software
Brand deals end the day you stop posting. An app doesn’t. We build the product your audience actually uses — mobile apps, web apps, members’ areas, tools, the lot — hand-coded and owned by you on day one. Your following is the launch your competitors would kill for; most creators waste it. These are the shapes that turn it into a company.
01 · Facet
SaaS products, member areas, booking flows — hand-coded, fast, owned outright.
02 · Facet
iOS and Android, native-feeling, on the same source you own day one.
03 · Facet
The screens your team works inside every day — real data, signed receipts, not a Retool wrapper.
04 · Facet
Client logins, account areas, self-serve dashboards — multi-tenant from the first commit.
05 · Facet
The DM & comment agent and bespoke agents — the AI that converts your audience and runs your brand, on a signed audit chain.
06 · Facet
Marketing sites and landing pages — hand-coded, conversion-tuned, no CMS lock-in.
07 · Facet
The systems you already run, wired together properly — retries, idempotency, observability. Code, not nocode.

What actually separates us
Most agencies assemble apps from rented SaaS. We engineer software you actually own. Here’s what that means in practice.
You own every line of code. You can fire us, change anything, host it anywhere. No per-seat fees, no per-task billing, no vendor lock. Most agency deals trap you in rented stacks. We never do that.
We don’t sell demos. We deploy software that thousands of paying companies already run — Cal.com, Twenty, ERPNext, Documenso, OpenBB. The foundations are enterprise-grade. We add the integration + brand layer your business needs.
Every action your AI takes is recorded, signed, and provable to your auditor. If a regulator or customer asks how a decision was made, you can show them. Most agencies don’t even keep a log.
Your receptionist remembers what your sales agent did last week. Your CRM knows what the chatbot told a customer two weeks ago. One memory layer underneath everything. Nobody at this price bundles this.
Everything runs under your account, on your hosting. Your data never sits next to another customer’s. Compliance-friendly for legal, healthcare, and finance work. The opposite of how most AI tools work.
We don’t bill you per AI call. Use as much as your business needs. We absorb the running cost because we’ve engineered the system to keep it close to zero.
Roman replies personally within one business day. No account-manager layer. No rotating juniors. The engineer who scopes your project is the engineer who builds it.
“If you can describe the software you need, we can build it. Owned by you, tested before delivery, with a written record of every action it takes after launch. That’s the whole bar.”
— Roman Puglielli, founder
Offering 02 — the agent that sells for you. Under every viral post are thousands of people ready to buy — and no human fast enough to answer them. The DM setter & replier does, in your voice, at your scale.
// Offering 02 — The DM setter & replier
It reads every comment and DM, catches buyer-intent even off-keyword, replies in your voice, and drops the link at the right moment — two layers: comments for reach, DMs for the close. It runs on the official Instagram and TikTok APIs (never a bot login), every reply is logged, and you set the line between what it sends on its own and what waits for your tap.
For creators, coaches & influencers — replies in your voice and converts the curious into customers
Under a viral post, thousands of curious people comment and DM — and almost none become customers, because no human can answer them all. This agent reads every comment and DM, catches buyer-intent even when they don't use a keyword, replies in your voice, and subtly converts — answering the objection and dropping the link at the right moment. Two layers: comments for reach, DMs for the close. It runs on Instagram and TikTok through the official APIs — never a bot login that risks the account. You set what it sends on its own versus what waits for your tap.
// The evidence
Reply in minutes, not hours
Speed-to-lead is the single biggest lever on converting an inbound — and no human hits it at viral scale. The agent answers the instant intent appears.
Every DM, answered
The comments and DMs you never had time for are where the buyers were hiding. Captured, qualified, and converted instead of ignored.
In your voice
Trained on how you actually talk, so it converts without sounding like a bot — the trust that makes a follower buy from you instead of scrolling past.
How we work
Four steps from first call to live deployment. Direct engineer contact throughout. No account-manager layer, no agency hand-offs, no rotating juniors.
Thirty-minute call. Operation mapped. Constraints understood. Fit assessed honestly — if we’re not the right shop, we say so on the call.
Written quote in one business day. Deliverables, timeline, price, ownership terms. No hidden fees. No vendor-lock clauses.
Async + weekly synchronous reviews. Build happens in your repo, your accounts, your environment. Source-owned the day code lands.
Production deployment. Signed receipt on every consequential action. Documentation. Optional retainer for ongoing changes.
// Questions creators ask
Yes — it’s the entire point of XXI. We build the mobile or web app your audience actually opens: your content, community, tools, and products in one surface you own outright. Most creators already have the hardest part (the audience) and are missing the asset. We build the asset.
Three ways, usually: a paid app or membership your audience subscribes to, a product or tool built for your niche that they buy, and the DM & comment agent that converts the followers you already have into customers. Unlike brand deals, all of it is owned by you and keeps earning after you stop posting.
It reads every comment and DM, catches buyer-intent even off-keyword, replies in your voice, and drops your link at the right moment. It runs on the official Instagram and TikTok APIs — never a bot login — so it stays within platform terms and never risks your account. You decide what it sends on its own versus what waits for your tap.
There’s no hard number, but the math works best once you have an engaged audience in the tens of thousands or more — enough that a small percentage converting is real money. On the discovery call we model your specific numbers so you can see the return before you commit.
Completely. Every line of code is yours, deployed to your own accounts, on day one. No vendor lock, no per-seat fees. You can take it in-house or keep us on a retainer — your choice, because it’s your asset.
Both depend on what you’re building. The DM & comment agent is the fastest to stand up; a full custom app is a larger build. Every engagement is fixed-scope with a written quote inside one business day of the discovery call — no open-ended hourly billing.
Thirty-minute discovery call. We figure out what to build for your audience, scope it, and write a quote within one business day.
