Application modernisation and legacy migration companies · Social media

Use LinkedIn to show how your engineers think about an old system.

Social media for a modernisation firm means LinkedIn above all, used to show the engineers' judgement on real migration problems. GullySales works on what the firm posts, who posts it and how replies from buyers are handled.

Developers reviewing application code and a migration plan

What social media means

Social media is the ongoing posting your business does on platforms such as Instagram, Facebook and LinkedIn to stay visible to customers and prospects between purchases. GullySales plans a posting calendar, writes captions and designs the images so the page looks active and answers what a visitor would ask.

For application modernisation and legacy migration companies

Where it usually goes wrong, and what we would do.

  • “LinkedIn is where the buyer's team already is”

    CIOs, architects and engineering managers read LinkedIn for peers' views. A firm page announcing partnerships is skimmed. A lead architect writing about a data migration mistake is read to the end.

  • “Company pages reach fewer people than the engineers do”

    The people who did the migration carry the credibility. When they post under their own names, with the firm's consent, the posts reach buyers who would never follow a company page.

  • “Confidentiality limits what can be shown”

    Client names, system diagrams and screens are off limits. The firm can still write about patterns, decisions and checks without revealing a client or weakening its security.

  • “Replies and messages are the real conversion”

    A comment from a CIO's architect or a message from a partner manager is the start of a sale. If nobody replies within the day, the conversation is lost to the next firm they follow.

What we do

What we deliver for application modernisation and legacy migration companies.

Every deliverable, what it covers for you, and the result it is there to produce. Nothing here is an extra.

  1. A posting plan built on engineers' experience

    A plan that names who posts, on what subjects, from which projects, with a review step so nothing confidential is shared.

    Result: A list of topics assigned to named engineers.

  2. A set of post formats for technical topics

    Formats such as a lesson from a cutover, a checklist for data verification or a question to ask before choosing a hosting move.

    Result: A bank of formats the team can reuse.

  3. A confidentiality review routine

    A short check that each post is read against client agreements before it goes out.

    Result: Every post carries a recorded approval.

  4. A reply and message routine

    Rules for who answers comments, how a message from a buyer is passed to sales and how a partner's message is routed.

    Result: A named person answers each message or comment.

  5. Engineer profile clean-up

    Profiles for the architects and delivery leads rewritten around the systems they have moved, with a link to the assessment page.

    Result: Each senior engineer's profile points to a page on their work.

How the result is measured

  • Posts published
  • Engagement rate
  • Enquiries from social profiles

Recorded as a baseline before work starts, so every later report has an honest comparison.

Posts and pieces to plan

Plan posts that let an engineer think aloud in public.

What broke first in a database move
A short post from the engineer who handled it, with a diagram redrawn without client names, since the lesson matters more than the account.
Strangler pattern in plain terms
A carousel explaining how the old system is replaced piece by piece, with one anonymised example and a note on what stays unchanged.
Questions to ask before a cutover
A checklist post from the delivery lead, which a CIO can forward to the team and which shows how the firm plans.
Reading a decades-old batch job
A story post about what the team found in undocumented code, shared only after the client has approved the wording.
Hiring note for a migration engineer
A job post that describes the real stack, drawing in the engineers who know it and signalling depth to buyers who read it.

Who it is for

This is written for these application modernisation and legacy migration companies.

  • Banks and NBFCs running core and loan systems built decades ago
  • Insurers with policy administration and claims platforms on old stacks
  • Hospital groups with a hospital information system nobody wants to touch
  • Manufacturers on ageing ERP customisations and plant-floor software
  • Logistics and supply chain firms with in-house dispatch and tracking applications
  • Public sector bodies and PSUs with tender-led replacement projects
  • Software product companies with a monolith that slows every release
  • Mid-sized companies moving data centres to AWS or Azure

Not for

It is not the right fit if.

  • No engineer is willing to appear or be quoted, and a page written only by marketing would read like every other vendor.
  • Clients have not agreed what may be mentioned, so every post would need to be pulled after review.
  • You expect posts to bring contracts by themselves, when the sale still depends on named accounts.

How it works

How the social media work runs

The work itself, in order. How an engagement starts, from your brief to a written scope, is set out on our method page.

  1. 1

    Confirm audience, platforms and access

    We note which platforms your buyers use and check that the pages sit under your own business accounts, with you as owner and us as added roles.

  2. 2

    Review the current presence

    We read the existing pages, the posts that drew replies and the gaps in posting.

  3. 3

    Build the calendar

    Themes, formats and dates are set out for your approval, with space for offers and news.

  4. 4

    Create, approve and publish

    Posts are made, approved by you and scheduled. Replies to the public are handled in your voice.

  5. 5

    Record enquiries and adjust

    Enquiries are logged against the post or platform where they began, and the mix changes to follow what brings them.

Where this fits

Three pieces of sales work, in this order.

This work sits inside sales process design, at stage 0, foundation. The audit comes before it, and sales management keeps it running.

  1. Step 1

    Sales audit

    Find where deals are being lost and what to fix first.

    Start here if you cannot say where orders are lost.

  2. Step 2 · you are here

    Sales process design

    One written way to sell, from first enquiry to repeat order.

    Start here if every salesperson sells differently.

  3. Step 3

    Sales management

    A target, a review routine and someone who owns the number.

    Start here if the team has targets and no routine.

FAQ

Questions owners ask before they call.

Not here? More answers, or ask on WhatsApp.

Tell us what you need
Should the founder post or the engineers?
Both, with different jobs. The founder speaks about the firm's view and the kinds of systems it takes on. The engineers speak about how the work is done. Buyers want to hear from the person who will run their migration.
Is paid LinkedIn advertising worth it for this trade?
It suits a narrow audience, such as engineering heads at named companies, and a specific offer like an assessment. Broad awareness spend reaches people who have no system to move. Start small and record which accounts engaged.
What do we do when a client does not want to be mentioned?
Respect it. Write about the method without the name, or leave the story out. A breach of trust with one client costs more than any post earns.
How do we post about a project under confidentiality?
Describe the problem and the method, remove names, systems and figures, and get written sign-off before posting. Banks and insurers treat their stack as sensitive, so a post that identifies them by detail can end the relationship.
How much does it cost?
There is no price list, because the work differs by business. The fee is scoped after we have read your brief and spoken to you, and put in writing before anything starts, split into our time, your media spend and production.
How long is the contract?
The term is agreed in writing after we have spoken, along with the fee and the reporting. It is never a default twelve months, and renewal is decided on the numbers against the baseline recorded at the start.
How soon will we see results?
It depends on the trade, the channel and what is already in place. After we have read your brief and spoken to you, we say what we would expect to move first and how it will be measured against the baseline. Nothing here is guaranteed.
Who will actually do the work?
The person you speak to before anything starts. We work from one office in Nagarbhavi, Bengaluru, with no account managers in between.
What do you need from us?
Your brief, and a conversation. After that, access to whatever this work touches, such as your website, your accounts or your enquiry record, and time with the people who handle your enquiries.
What if we are not happy with the work?
Tell us and the plan changes. Everything is reported against the baseline, so a number that is not moving is visible to both sides. The term is in your written scope, and the refund and cancellation policy sets out the rest.
